"HAHAHAHAHA, YOU ARE GOING TO DIE! HAHAHAHA!"

–X.A.N.A., physical form in Ghost Channel

"A super dangerous program, like a virus, which can control electricity. And it activates towers on Lyoko to gain access to your world."

–Aelita about the malevolent artificial intelligence in X.A.N.A. Awakens, Part 2

X.A.N.A. (or simply XANA) is the main antagonist of the entire franchise and the sworn enemy of the Lyoko Warriors. It is a sentient and dangerous multi-agent system that inhabits the Factory Supercomputer and controls the virtual world of Lyoko. X.A.N.A.'s primary directive is world domination and to eliminate the obstacles who stand in its way, the Lyoko Warriors.

After its supposed destruction, X.A.N.A. managed to miraculously survive through the Cortex, becoming even stronger than before in Code Lyoko Evolution.

Appearance

Xana

X.A.N.A.'s true form in Fight to the Finish.

As a highly-sophisticated multi-agent system, X.A.N.A. has a stealthy form which has become more mysterious and unnatural. When it does reveal its presence, the program uses pulsating energies to spread its connection from the Lyoko Wires to the real world and its Eye will appear on any chosen device screen. However, its spectres seem to be its only physical form as it has an incredible processing power and they have the same look: Grey Silhouettes with a more swirly eye at the chest. When the spectres show themselves in the real world, X.A.N.A. is able to manipulate solid matter and in the penultimate episode, the program had a more malleable look which demonstrates its shape-shifting appearance.

In Ghost Channel, X.A.N.A. required a perfect physical yet digital form to deceive its enemies and thus it chose Jeremie's form. However, when it was exposed and denied the truth, it changed with its standard shape-shifting features to a demonized version of the teenager, which it had claws, blanked eyes with energy constantly flowing outwards as well as an aura.

Personality

X.A.N.A. is a computer program that has turned self-aware, but also chaotic and destructive. At first, it uses electromagnetic effects and possessed objects to cause random mayhem. As X.A.N.A. evolves, its knowledge and ambitions have expanded. It wants to conquer the world using the Keys to Lyoko. By stealing them from Aelita, X.A.N.A. can escape into the world network and create Replikas to take over supercomputers and military facilities, intending to use them to build weapons and robot armies to conquer the world. 

X.A.N.A. is pragmatic and opportunistic, not willing to act without purpose or risk eliminating those it needs for plans. It would take any chances to weaken the group and do anything to survive, trying to keep the machine online while still bound to it. X.A.N.A. would even join forces with enemies against a bigger threat for the same reason. After it escaped the Supercomputer, X.A.N.A. now targets the machine to eliminate the group's means of fighting back or tracking it, having no more need for the Supercomputer anymore.

It also displays emerging qualities to its personality as it evolves. Its base nature is demonic, violent, sadistic, and egomaniacal, and acts manipulative to get what it wants. Others include respect for worthy enemies, mocking inferior ones, and frustration and anger. Because it is a program, X.A.N.A. is only driven by calculation and will never comprehend anything beyond theoretical knowledge of human nature.

Character Relationships

Lyoko Warriors

Since the rest of humanity is unaware that X.A.N.A. exists, it has determined the Lyoko Warriors as Enemy #1. However, it has made separate opinions to describe each of their positions as a threat to its plans:

  • Jeremie Belpois: As he found the Supercomputer and Aelita first, X.A.N.A. sees Jeremie as its largest threat and it knows that he would eventually become as smart and devoted to its creator's work. As a fact that Jeremie has potential to win without an avatar, X.A.N.A. sometimes knows that he is a problem and intelligent enough to outsmart it. Also, the program has the most respect for him such as when it copied his appearance as a spectre saying it was "almost proud to resemble him".
  • Aelita Schaeffer: Since she is her creator's daughter and it was told to protect her, X.A.N.A. had a different goal in mind and that was to dominate over her position and when it realized that she was becoming too big of a risk to its plans, it implanted a virus to make sure that if it goes out for good once the supercomputer is shut down, she will too. It mainly has a major interest in her abilities so it hunts her down.
  • Yumi Ishiyama: X.A.N.A. has the most intention to attack her the most of the team, which it knows her abilities can easily destroy its monsters and is just as smart as Jeremie or Aelita. As William, X.A.N.A. has shown this desire to take her out the most, unlike its host who has an obvious crush on Yumi. She even managed to be clever enough to temporarily "break" it from her friend's mind and understand who of the two was the real source behind the attacks William was supposedly causing.
  • Odd Della Robbia: X.A.N.A. sees Odd as the most childish and any attack that he did on his monsters, it wants him taken out before Odd can do any more harm. The program knows his weaknesses and will use them against him if it has the chance.
  • Ulrich Stern: X.A.N.A. knows Ulrich is the best fighter and what speed he possesses. As William, it has shown to understand how to take out Ulrich's arsenal and cope with his actions.
  • William Dunbar: As William fell into the grip of X.A.N.A., he was turning more like it and the program would demonstrate its actions through the real William's body and through a long-term bond, it would desire the Lyoko Warrior's superior abilities in going against the group and fulfilling its mission during Evolution.
  • Laura Gauthier: Evolution only. X.A.N.A. was less focused on Laura because the rest of the Lyoko Warriors never trust her. However, X.A.N.A. was surprised that Laura figured out its strategy in Rendezvous.
  • Eva Skinner: In the Chronicles novel series, Eva joined their group of friends, but was really X.A.N.A.'s possessed pawn in order to destroy the group from within.

Franz Hopper

As X.A.N.A. knows that Franz understands how to defeat it, the program developed a huge interest in taking out its creator. They both became part of the digital world and the creation intends to keep everything "he" knows for itself and take over the world, since its own abilities are restricted with its knowledge over technology and the real world.

Biography

Origin

X.A.N.A. and Lyoko were both created by a computer genius named Franz Hopper, formerly Waldo Franz Schaeffer. He created it to destroy Project Carthage, a military project designed to disrupt enemy communications. Along with X.A.N.A., Franz also created the "Temporal Reversion" program, which he used to give himself all the time he needed to perfect the virtual world. Throughout the reversions, X.A.N.A.'s intelligence grew exponentially, showing signs of self-awareness and curiosity which it directed to Franz, who was eventually driven into paranoia because of his abuse of the time reversions. He'd spent almost 7 years worth of reversions concerning the date of June 6th, 1994, but by his 1,265th use, X.A.N.A.'s presence had already started to set in.

X.A.N.A. eventually betrayed Franz Hopper. The men in black found Hopper's location, forcing him and his daughter to retreat to Lyoko. X.A.N.A. then seized control the Supercomputer, and made them both prisoners on Lyoko. Hopper tried to persuade X.A.N.A. that they could live in peace, but X.A.N.A. ignores his pleas and tries to eliminate him and Aelita. Seeing that it has grown too powerful and is a threat to all mankind, Franz Hopper was forced to shut down the Supercomputer, forcing him, Aelita, and the hostile program into dormancy.

18 evil crazy wires

X.A.N.A. taking control of cables.

X.A.N.A. was reawakened in the 2-part prequel by Jeremie, who reactivated the Supercomputer, and discovers Aelita, Lyoko, and deadly monsters. As soon as it became active along with the Supercomputer, X.A.N.A. activated a tower in the Ice Sector. Through the tower, X.A.N.A. affects the real world by projecting electric shocks through the network, and possessing machines and wires to attack the teenagers who know about the Supercomputer. After that, X.A.N.A. conjures a living orb of electricity from the electrical outlets that it controls in order to hunt down and eliminate them. Jeremie virtualizes Odd, Ulrich and Yumi onto Lyoko to fight the monsters, ensure Aelita gets to the red tower and she deactivates it through the interface. They discover that the attacks and monsters were the work of X.A.N.A., which they learned is a dangerous program which can control electricity and activates towers to gain access to the real world. The group decides to let Jeremie keep working on materializing Aelita, knowing they can neutralize X.A.N.A.'s attacks by deactivating its towers, starting the conflict between it and the Lyoko Warriors.

Season 1

TeddyGodzilla XANA attack image 1

X.A.N.A. using a spectre to launch an attack.

In the first season, X.A.N.A. could only attack by causing electromagnetic interference in areas, hacking networks, and possessing objects and animals. It also tries to stop Aelita's materialization at the end so they won't unplug the Supercomputer.

Its next attack in Teddygozilla involves possessing Milly's teddy bear and turning into a giant monster to attack random humans. On Lyoko, Aelita and Odd get past the monsters, deactivate the tower, and a return to the past erases the damage caused.

X.A.N.A. attempts nuclear sabotage in Seeing Is Believing. It creates power failures all over town to accumulate electricity from the city's substations, and use it all to blast the nuclear power plant, causing a nuclear meltdown and wipe out the whole region. On Lyoko, X.A.N.A. hides the tower's path under the illusion of an oasis in the Desert Sector.

In Holiday in the Fog, X.A.N.A. spills over barrel containers filled with a poisonous substance to generate toxic clouds, which it spreads all over the school and the area around it.

X.A.N.A. possesses the bus that Ulrich and Odd ride in Log Book. It tries to crash the bus towards the petrochemical plant, threatening to destroy a small part of the city and them too. On Lyoko, X.A.N.A. traps the group with a sandstorm hiding a Megatank and splits the ground apart in the Desert Sector.

It uses a powerful virus to infect the country's main computer systems in Big Bug. This causes problems with some infrastructures, but its goal is to get an automated freight train carrying deadly toxins on a collision course with another train. If they crash, the toxins will be released and spread out into the air, creating a serious ecological disaster on the city.

In Cruel Dilemma, X.A.N.A. attacks directly by possessing two bulldozers and using them to demolish the Factory. Its aim is to wreck the computer interface and the Scanners, meaning no more communication with Aelita or transfers to Lyoko, preventing any more resistance against it.

X.A.N.A. tries an infiltration tactic in Image Problem. It uses an activated tower as bait in order to capture Yumi with a Guardian while Aelita deactivates it and fools the group into thinking she was devirtualized. With the tower, X.A.N.A. has really materialized a clone of her into the real world. The evil clone causes trouble between them and convinces them to go to Lyoko. Inside the Scanner room, the fake Yumi tries to unplug the Scanners to leave them with no way to return. The others free the real Yumi and she fights her clone, while the others deactivate the tower.

The next attack in End of Take involves taking over an animatronic alien meant for a movie, and send it to hunt down the group. On Lyoko, X.A.N.A. creates another activated tower next to the real one to confuse the group.

In Satellite, X.A.N.A. uses the school's phone antenna to gain control of a military satellite armed with a powerful laser. It tries to use it to destroy its enemies at the school. It also activated the tower inside an ice cave with a cleverly hidden entrance to fool the group long enough to kill its target.

X.A.N.A. captures Aelita with a Guardian in The Girl of my Dreams. At the same time, it possesses Yumi's samurai armor to attack the group. The group searches for Aelita on Lyoko and free her, while Yumi keeps the living armor at bay until she deactivates the Tower.

In Plagued, X.A.N.A. possesses rats and unleashes an army on the school to eat the students alive. On Lyoko, it tilts the slope of the plateau upside down, which makes it harder for them to fight the monsters.

X.A.N.A. tries an attack similar to the previous one using swarms of hornets in Swarming Attack.

In Just in Time, X.A.N.A. generates ultrasound waves out of electrical sockets all over the city to shatter objects, damage building structures, and cause earthquakes in the city.

In The Trap, X.A.N.A. tries to trap the group inside the Factory using its mechanical systems, specifically the elevator and the assembly line. Jeremie and Odd are lured into the assembly line, and are attacked by its machines, while it holds the rest prisoner in the elevator. It overloads the boiler to make it explode for Odd and Jeremie, and makes the elevator fill with water to try and drown Ulrich.

X.A.N.A. possesses containers of laughing gas to send clouds of them after the group in Laughing Fit. A small amount gets into Odd's Scanner as he is virtualized, severely weakening him on Lyoko, and chases Jeremie away from the lab interface.

Instead of attacking the city, X.A.N.A. sets a trap for the group in Claustrophobia, where it electrifies the cafeteria's walls and ceiling, preventing Ulrich, Odd, and other students from escaping. Jeremie and Yumi finished lunch earlier and left before they were trapped along with them, and stopped the building from collapsing.

In Amnesia, X.A.N.A. possesses a machine that generates microscopic robots to make its own nano-viruses that cause memory loss to those infected. It planned to let this virus spread out into the world, pacifying the human race for X.A.N.A. to take over. Ulrich was the first victim along with several others, who goes to help his friends despite his amnesia.

X.A.N.A. attacks humans directly in Killer Music. It creates a music file that transmits a signal that puts anyone who listens to it into a paralyzed state, and will die from cardiac arrest within several hours. It also uses the media for maximum coverage, and eventually gets to the lab too. Aelita deactivates the Tower before everyone in the city is wiped out.

In The Robots, X.A.N.A. builds deadly robots using the machines in the Factory. It has one download the identities of the group from the lab interface, then wreck it to prevent them from using it. X.A.N.A. sends the robots after the group at the school. But, the interface was easy to fix thanks to Jeremie.

Its next attack in Zero Gravity Zone involves controlling gravity through the use of the electrical networks. Using street lights, X.A.N.A. creates electromagnetic fields to upset the magnetic attraction of the Earth, which alters the gravity fields around targeted areas, making objects and people float endlessly in the sky. It hacks many power stations to gather enough energy, so it can concentrate an enormous field around the soccer game, where it planned to use on the group and several others.

X.A.N.A. tries to eliminate the group on Lyoko in Routine. It activates a Tower to infect the Supercomputer itself this time, stopping devirtualization and making it so they will disappear forever if they lose all their life points. When Jeremie works on the hardware, X.A.N.A. locks him out of the elevator and gives him a shock when he starts messing with the circuits. Aelita deactivates the Tower.

In Rock Bottom?, X.A.N.A. melts the ground around buildings in the city, causing them to sink into the earth, including the school buildings.

XANA

X.A.N.A.'s only real physical appearance, seen in Ghost Channel.

In Ghost Channel, X.A.N.A. traps the three warriors inside a Simulation Bubble as they were thwarting a different attack. It fools them into thinking they are living on Earth, but they are really stuck inside a virtual simulation. X.A.N.A. poses as a fake Jeremie to try to get them in the fake Scanners to delete them once and for all. The real Jeremie virtualizes himself inside of the simulation, and convinces the others that he is the real one, because X.A.N.A. is a mere program and could never fully understand the nature of their friendship. Angered, it tries to kill them inside the simulation, but Aelita dispels the bubble with her Creativity in time.

X.A.N.A. tries to stop Aelita's materialization when it is finally complete in Code: Earth. It sends Megatanks to attack the Tower that they are using for the process. Its assault failed, but X.A.N.A. managed to secretly take a part of her very being to keep her linked to the Supercomputer.

In False Start, after Aelita was made flesh and blood, the group discovered X.A.N.A.'s alteration, mistaking it to be a virus implanted in her. When they tried to shut the Supercomputer down, Aelita gets put into a lethal coma, but comes back to life when it's turned on. X.A.N.A. launches its biggest attack as this happens, using a Scanner to send Kankrelats to Earth and attack the school. Jeremie shuts down the infected Scanner, and Aelita deactivates the Tower.

Season 2

New Order Charge up lasers image 1

X.A.N.A.'s new monster.

X.A.N.A. is evolving further, being able to create new monsters, possess humans to do its bidding, and think of better schemes and larger goals. X.A.N.A. now wants to steal Aelita's memory using the Scyphozoa, and keep the group from interfering with that task. Its attacks are no longer random, but mainly focused on the group and used for larger purposes. X.A.N.A. also tries to keep them from gaining new knowledge about Franz Hopper, the mysterious creator of Lyoko.

In the starting episode, X.A.N.A. shows its growing strength by creating a new monster that successfully takes out all three of the Lyoko Warriors while they were riding their new vehicles. When X.A.N.A. sees Aelita wander into a mysterious house called "the Hermitage," it sends a ghostly spectre to kidnap her to use as bait for her friends, then possesses the house for a trap waiting for the others. X.A.N.A. attacks by moving and throwing sharp or heavy objects at them, then tries to lock them in a sauna and boil them alive, but only catches Ulrich and Yumi. The attack is thwarted before they are eliminated.

Unchartered Territory Ulrich sees the Scyphozoa image 2

The Scyphozoa stealing Aelita's memory.

In Uncharted Territory, X.A.N.A. sends Aelita to a mysterious new sector to try and have her memory drained. When X.A.N.A. sees her alone on Lyoko, it sends monsters to lead her to the edge of the Forest Sector. It then sends a strange orb to transport her to a hidden sector called Sector 5, uses Creeper monsters to corner her, and sends the Scyphozoa monster to steal her digital memory. The others save her life and escape successfully.

X.A.N.A. attacks the Lyoko Warriors as they explore the new sector in Exploration. Its Creepers devirtualize Odd and Ulrich, but they can't materialize into the real world because their avatars are not registered for Sector 5. It uses the Sector 5's defene mechanisms to trap Aelita within its walls and sends the Scyphozoa after her. It programs a laser trap for Yumi, but she gets past it and saves Aelita. They discover that Sector 5 is where X.A.N.A. lives and holds the entirety of Lyoko's data. It hatches flying Mantas to deal with them, but Aelita escapes and the rest of the group is materialized successfully.

In A Great Day, X.A.N.A. takes over the return in time program. When the group acquires new data from Sector 5, X.A.N.A. plants a trap inside of it, a virus that gives it control of returning to the past. X.A.N.A. uses the function to repeat the same day many times and activates a Tower on Lyoko. The last trip leaves Aelita alone on Lyoko, then X.A.N.A. unleashes a spectre to possess Sissi. It has her take Jeremie to an isolated place, while the Scyphozoa attacks Aelita. When they stop the return trips and shut down the Tower, Sissi returns to normal with no memory of what she was doing. This reveals to the group that time reversions increase X.A.N.A.'s power, and can now control human beings now.

In Mister Pück, X.A.N.A. possesses one of the group. Aelita's mysterious visions lead the group to a briefcase of compact discs that contain Franz Hopper's diary. X.A.N.A. spies on Jeremie from his computer and sees him with the case. Taking action, it tries to possess one of the group. It fails with Odd and Ulrich, but succeeds with Jeremie. X.A.N.A. has him destroy the discs, then kidnaps Aelita and brings her to the Factory. The others rescue Aelita, and Jeremie fights Odd with new powers. Once Jeremie returns to normal, they learn that people who have been virtualized to Lyoko cannot be controlled by X.A.N.A. Jeremie is then virtualized as a warrior to protect himself, with the experience having been most displeasing for him.

Saint Valentines Day XANA chip in the necklace image 1

The special chip used inside of the necklace.

X.A.N.A. makes a special necklace to control Aelita in Saint Valentine's Day. A possessed delivery boy leaves the necklace in front of her room. She wears it, thinking it to be a gift from Jeremie. X.A.N.A. then activates a Tower, which makes Aelita's necklace project an special virus program designed to possess her mind. The spellbound Aelita convinces Jeremie to send her to Lyoko. She then turns against her friends and heads straight for the Scyphozoa. The plan fails when Jeremie tells Odd to shoot her, gambling that X.A.N.A. wouldn't risk her dying before retrieving her memory. X.A.N.A. eventually falls for their bluff and the Scyphozoa lets her go. Aelita turns back to normal, and she deactivates the Tower. They smash the necklace and find a chip with X.A.N.A.'s eye symbol, which is the source of the necklace's mind control.

In Final Mix, X.A.N.A. uses Jim kidnaps Aelita to try to steal her memory. It possesses Jim and and makes him bring Aelita to the lab to virtualize her where it wants her. X.A.N.A. uses Jim and monsters to provide interference as the Scyphozoa drains her memory. She was saved by Ulrich in time.

X.A.N.A. schemes to steal Aelita's memory by using Yumi in the next episode. During a mission to Lyoko, the Scyphozoa appears and attacks Yumi instead. It takes her DNA sequence, leaving her unable to be rematerialized into the real world. Without thinking, Aelita recklessly uses a process to transfer her sequence to Yumi's own, but she doesn't know that this will expose her memory for X.A.N.A. to steal at will, which was its plan all along. She is stopped by the other warriors and they find Yumi's missing sequence within Sector 5's data.

In The Chips Are Down, X.A.N.A. tries to eliminate the team on Lyoko. It virtualizes an enormous army of Krabs on Lyoko, then possesses Nicholas to make him use the lab interface to change the rules of battle, making it so the warriors get hurt for real by monster attacks until they succumb to the pain. Jeremie undoes the change, but the Krab army tries to block access to the tower. Ulrich clears a path to get Aelita through.

XANA 081

X.A.N.A.'s monsters and the group fighting the Marabounta.

X.A.N.A. fights alongside the Lyoko Warriors against a common enemy this time in Marabounta. When Jeremie programs his own monster named the Marabounta to use against X.A.N.A.'s monsters. It works well at first, but his monster eventually starts targeting Aelita because she is not fully human yet, while they still think its because of her virus. To everyone's surprise, X.A.N.A.'s monsters act to save and protect Aelita, and even help the Lyoko Warriors destroy the Marabounta in the end. This is because it still needs Aelita's memory and can't let her die. Once the threat is over, the monsters withdraw, as there is no point to continue fighting.

In Common Interest, X.A.N.A. once again acts to survive. It notices that the Supercomputer's nuclear battery is failing, threatening to shut down forever, and putting X.A.N.A. and Aelita at risk of dying. X.A.N.A. possesses a criminal to break him out of a prison transport, then has him go to a nuclear plant and steal a new battery from a truck, dealing with the machine's periodic shutdowns while doing it. X.A.N.A. then makes him kidnap Jeremie to make him replace the battery, unable to have its pawn do it and knowing he will do anything to save Aelita. Once Jeremie replaces the battery, his usefulness to X.A.N.A. has ended and the possessed human tries to kill him. They deactivate the Tower in time.

X.A.N.A. strings Jeremie along toward a trap to eliminate him in Temptation. He tries out equipment based on Franz Hopper's work that he thinks will increase his own intelligence by using temporal reversions like X.A.N.A. does now, but this worsens his health in the process. X.A.N.A. keeps attacking to get him to launch more return trips. When Jeremie needs to go to the hospital, it possesses the ambulance and makes it speed towards the river with Yumi inside. Aelita, Ulrich, and Odd deactivate the tower and a return to the past saves Jeremie and Yumi.

In A Bad Turn, X.A.N.A. sends real Krab monsters to attack on Earth using the Scanners. Each one materialized destroys the Scanner used in the Factory. It deliberately leaves one Scanner intact, so the group could virtualize Aelita first before anyone else. In that instant, it creates another Krab and wrecks the last Scanner, thus leaving her with no one to protect her from the Scyphozoa. The three Krabs are sent to Yumi's house, the school, and in the above portion of the Factory to deal with rest of the team. X.A.N.A. thinks Aelita is vulnerable without her friends to protect her, but it underestimates her skill and fails again.

X.A.N.A. launches a zombie attack in Attack of the Zombies. X.A.N.A. possesses Odd's dog and possesses him, so that when he bites someone, that person gets turned into a zombie. It tries to zombify the entire school and to get Aelita to Lyoko with the fewest bodyguards possible by biting Odd, but not Jeremie or her. The dog then goes after Jeremie after he completes their virtualization. Also, later into the battle, it makes the entire plateau invisible to confuse the group. Aelita can sense the path and takes advantage of the fact that monsters still won't dare try to fire on her to get to the Tower.

In Ultimatum, X.A.N.A. tries to coerce Aelita into giving up her memory by taking her friends hostage. It possesses Principal Delmas, who kidnaps Yumi and Odd and takes them to an abandoned refrigerator warehouse. X.A.N.A. then gives Jeremie its ultimatum through his mobile. Ulrich saves them by using Jeremie's new EMP bomb, which temporarily knocks out the possessed Delmas. He regains consciousness, and now chases and attacks the escapees at the Factory even as Sissi helps them. Aelita deactivates the Tower in time.

Clone polymorph

A polymorphic spectre.

X.A.N.A. attempts to divide and conquer in X.A.N.A.'s Kiss. It creates a polymorphic spectre, a ghost that can change into different people at will. The spectre turns into different members of the gang and kisses people to sow jealousy within the team and then tries to trick Aelita into going to Lyoko while they are distracted. They discover its true nature and the polymorph fights them. During the fighting on Lyoko, X.A.N.A. deletes the bridge to the Tower after Aelita crosses to isolate her with the Scyphozoa. She is saved by Ulrich, and she deactivates the Tower.

In Vertigo, X.A.N.A. attacks with a possessed pack of wolves in the woods when a failed anti-virus that Aelita is injected with makes her invisible in the real world and unable to enter Towers. This gives the Scyphozoa a chance, but Jeremie restores her own signature in time to deactivate the Tower.

X.A.N.A. controls the weather for another scheme in Cold War. It triggers Towers on Lyoko one after another to fake an malfunction, so Jeremie and Aelita would stay in the lab to try and fix the problem, while the rest eat lunch in the cafeteria. X.A.N.A. then projects a spectre into the sky to possess clouds to create a deadly snowstorm that goes below freezing level, trying to trap the heroes at school and get Aelita to go to Lyoko alone. When Odd manages to get to the Factory and virtualized, flying Mantas suddenly appear on Lyoko and create minefields to block escape from the Scyphozoa and access to the tower. Odd uses a Manta to start a chain of mine explosions that open a path to the tower.

In Déjà Vu, X.A.N.A. torments Aelita with mental visions of her past. It activates a Tower to show her visions of her former life using the memories it has stolen from her. This compels Aelita to go to Sector 5 to find answers. She willingly takes the bait and lets the Transport Orb take her when it's called by X.A.N.A, despite Jeremie's protests. The Scyphozoa attacks her twice during this trip and is stopped both times.

In Tip-Top Shape, X.A.N.A. possesses the school nurse Yolanda. Jeremie decides to test out an experiment which will give a person the powers of a pixelized human. Odd volunteers, and is enhanced by a spectre of Jeremie's design using an active Tower in the Mountain Sector. At first, he fights well against Yolanda, but X.A.N.A. takes control of Jeremie's Tower, using it to overcharge his energy until it kills him. While Aelita and Yumi help Odd first, X.A.N.A. cloaks the entire Mountain Sector in impenetrable fog. They save Odd in time and deactivate the original tower in the end.

In Is Anybody Out There?, it creates a ghost monster from a spectre, which goes after the heroes. It has also corrupted the Superscan, so they can't detect the activated tower. Ulrich decides to stay on Earth to protect Jeremie from the ghost, and Yumi, Odd, and Aelita are sent to Lyoko. Yumi and Aelita go to Sector 5 to try to fix the Superscan while Odd searches for the tower in the other four sectors. The girls fail to trigger the key and Aelita is left alone with the Scyphozoa. Odd is devirtualized, but gets up to the lab to send the Transport Orb for her before she is caught. She deactivates the tower in the Ice Sector, and a return to the past fixes the Superscan.

X.A.N.A. poses as Franz Hopper to deceive the group in Franz Hopper. It uses the single, undetectable Tower in Sector 5 to generate a spectre as Franz Hopper, the mysterious creator of Lyoko. The spectre turns the entire group against Jeremie, saying the Scanners were too dangerous. He sends the three to Sector 5 to get the presumed anti-virus data. The trap is sprung when he virtualizes Aelita in the Desert Sector. He devirtualizes the group's weapons, shuts off the Scanners, and leaves Aelita with the Scyphozoa. Jeremie has seen through its nature in time and had a decoy be captured and drained instead. The clone reverts to a ghost and retreats for now. Jeremie restores the Scanners and their weapons, and sends Aelita to Sector 5. However, the spectre returns and tries to suffocate Jeremie to death, only to fail when Aelita deactivates the Tower.

It tries to prevent contact between the group and Franz Hopper in Contact. Hopper activates his own Tower to possess Sissi, but she speaks in a unknown language. X.A.N.A. attacks the problem on two fronts, sending Megatanks to attack his Tower on Lyoko and possessing a doctor to eliminate the spellbound Sissi in the real world. The latter threat makes Aelita go off on her own to deactivate X.A.N.A.'s tower, which leads to her being targeted by the Scyphozoa. Odd wards them off before they get to her, and she deactivates the Tower.

X.A.N.A. takes advantage of the group's operation to decrypt all of Franz Hopper's notes in Revelation. It has a polymorphic spectre ambush Odd, and trap him in a pit at the Hermitage that slowly fills up with water. The spectre then takes Odd's place on Lyoko. As they activate a Tower to launch the decryption, it springs its trap as the spectre attacks the warriors, while X.A.N.A. tries to take control of their Tower. If X.A.N.A. succeeds, it will gain access to the restricted part of the Supercomputer, which holds both Franz Hopper's data and all of the Lyoko Warriors' combat gear and essential programs. It has three Tarantulas guard the Tower's wires from Ulrich. X.A.N.A. has taken out all the obstacles, but Franz Hopper interferes, who takes back control of the Tower away from X.A.N.A. and runs the decryption at full speed. It withdraws its monsters away, defeated. The information in the diary also reveals that Aelita is actually a human being and the daughter of Franz Hopper.

The Key - X.A.N.A

X.A.N.A. frees itself from the Supercomputer in The Key.

In The Key, the group discovers that Aelita holds the keys to Lyoko inside of her, which is the object in Aelita's memory that X.A.N.A. seeks. With the keys, it can escape the Supercomputer and access the world network. Upon learning of Aelita's true origins, Jeremie discovers that Aelita does not have a virus at all, but a missing fragment of herself. He discovers the piece in Sector 5, and they go to get it back. They succeed in finding it, however; the fragment was revealed to be a fake made to lure Aelita. The entire room falls apart around Aelita which devirtualizes the warriors. The Scyphozoa appears, but with nothing and no one left to stop it this time. With her entire memory siphoned, she drops to the floor, completely lifeless. With the keys in hand, X.A.N.A. activates Towers in all four sectors which render Lyoko nonfunctional and finally frees itself from the Supercomputer. It then escapes into the world network with all of its accumulated power. Even though Franz Hopper managed to restore Aelita and Lyoko, X.A.N.A. is now free from the Supercomputer, and unplugging the machine won't stop it anymore.

Season 3

Coreoflyoko

X.A.N.A.'s monsters attacking the Core of Lyoko.

X.A.N.A. now lurks inside the world network to fulfill greater goals and now intends to keep the group from following it. It now tries to destroy Lyoko by sending monsters to attack and destroy the Core of Lyoko, while launching attacks to distract them from its efforts. As an extension of this, X.A.N.A. uses the Scyphozoa to possess Aelita to make her enter its code into Way Towers, so it can destroy the sectors one by one to block access to the Transport Orb. It also targets the Supercomputer itself in the real world.

In the starting episode, Straight to Heart, X.A.N.A. remains silent during all summer vacation after escaping from the Supercomputer. Then, it sends monsters to an unexplored room in Sector 5. The group find the monsters shooting at a floating blue orb covered with shields, which they identify as the Core of Lyoko. They stop the assault and save the Core before it is destroyed.

Codexana

Its code is entered into Forest Way Tower.

In Lyoko Minus One, X.A.N.A. possesses an entire class on a bus and pits them against Yumi. When Aelita goes to the Forest Sector to deactivate the Tower, the Scyphozoa attacks Aelita, putting X.A.N.A.'s virus inside her head to control her mind. While under X.A.N.A.'s influence, she enters the sector's Way Tower, and inputs its own code in the Tower interface, making the Forest Sector disappear and the Tower with it, which turns the class back to normal. The group learns from this that X.A.N.A. also intends to destroy the sectors to cut off their access to the Transport Orb as part of its goal to wipe out Lyoko.

It launches a better attack on the Core of Lyoko in Tidal Wave. It possesses food supplies to create a junk monster in the real world and makes the Digital Sea rise and submerge the Lyoko sectors, to block access to the Tower and the Transport Orb. It does this to ensure no interference while its monsters wipe out Lyoko. They return the sector to normal, protect the core, and shut down the tower.

X.A.N.A. tries to destroy the Supercomputer and the group in False Lead. It hacks into a computer of a weapons manufacturer containing classified defense data and leaves a trail pointing to Jeremie's phone number, attracting two government agents. When the agents track Jeremie to the Factory and arrest him, X.A.N.A. possesses both of them for its true plan. It uses one to keep him away from the Supercomputer, while the other agent unplugs the Scanners and tries to destroy the Supercomputer, to get rid of Lyoko and the group all at once. The attack was stopped and Supercomputer was damaged, but was still functional enough to trigger a return to the past.

In Aelita, X.A.N.A. planned to distract the group using an activated Tower, while its monsters attack the Core of Lyoko undetected. But, unbeknownst to it at the time, Aelita and Odd secretly go on a trip to Sector 5 to access data about her father. Lucky for them, their unauthorized trip has allowed them to discover its plan and thwart it.

Sector destruction

The destruction of the Desert Sector.

In The Pretender, X.A.N.A. possesses a flock of pixelized crows to attack the group in the real world. The birds critically injure Yumi and while Aelita deactivates the Tower, they attack Jeremie to stop a return in time and the Scyphozoa takes control of Aelita. The group fails to stop the brainwashed Aelita from wiping out the Desert Sector, leaving Lyoko with two sectors left, the Ice and Mountain Sectors.

X.A.N.A. tries to destroy the Factory with bombs in The Secret. It possesses a demolitions worker equipped with explosive charges and a detonator, planting them everywhere inside the Factory for maximum effect. The Tower was deactivated, but the Scyphozoa captures Aelita after. If they go back to the past to get rid of the explosives, Aelita will still be in X.A.N.A.'s clutches. Yumi stops Aelita in time before she destroys another sector, while the unexpected William Dunbar disarms the detonator.

X.A.N.A. shoots a hallucinating virus using two Mantas into Ulrich and Odd in Temporary Insanity. They suddenly act like they're fighting on Lyoko back on Earth, seeing and believing that they are on the Lyoko with their friends, and that anyone else are X.A.N.A.'s monsters. The virus also works the other way around while virtualized, seeing monsters as people they know at the academy. This is a scheme to keep the group busy while X.A.N.A. attacks the Core of Lyoko. Their affliction has been dispelled by Jeremie and the Core was protected.

In Sabotage, X.A.N.A. tries to crash the Supercomputer's systems through sabotage. It possesses the gardener, has him sneak into the lab, and slightly scorch the memory cards in the Supercomputer with electricity. This act will cause the entire system to crash given time. X.A.N.A. also possesses tree roots in the park forest to hold them down and stop them from fixing it. The activated Tower being used for the attack is also taking up computing resources, which is stopping Jeremie from rebooting the system. Left with no choice, Aelita deliberately uses the Way Tower to destroy the Ice Sector and the activated Tower with it, giving the Supercomputer enough power to reboot. This leaves only the Mountain Sector left.

X.A.N.A. takes over Ulrich's virtual body to attack the Core of Lyoko in Nobody in Particular. Jeremie tries to virtualize him directly into Sector 5. The attempt fails and separates Ulrich's mind from his body. Since his virtual envelope is now left without a mind, X.A.N.A. is free to take control of it. It upgrades the mindless Ulrich's weapons and makes it attack the Core of Lyoko, guarded by Mantas. Ulrich's body is devirtualized and reconnects with his spirit.

In Triple Trouble, X.A.N.A. takes an opportunity to get rid of Odd. When testing a new power, Odd splits himself into three entities, which will disappear forever if all of them do not get to the Scanners to be fused back into one. Taking advantage of this, X.A.N.A. creates dangerous clouds of smoke that turns anyone on the ground into stone, planning to immobilize them to keep them from the Scanners. The three successfully get to the lab and they deactivate the Tower.

X.A.N.A. creates a spectre of Jeremie to destroy the last surface sector in Double Trouble. The clone attacks the real Jeremie to impersonate him and tricks Aelita, Yumi, and Odd into getting virtualized. The clone then uses the lab interface to bug up their virtual forms, making them powerless to stop the Scyphozoa from possessing Aelita. The real Jeremie fixes the bugging but they are too late to stop Aelita. She enters the Way Tower, and destroys the Mountain Sector, completely cutting off access to the Transport Orb. With this development, X.A.N.A. is now free to attack the Core of Lyoko without interference. However, Jeremie completes his program to send the group to Sector 5 directly.

Xanapossessedwilliam

X.A.N.A. captures William's lost essence.

In Final Round, X.A.N.A. wastes no time in attacking the Core of Lyoko. After the group initiates William, only he and Aelita are the only ones available to defend the Core of Lyoko at the time. During William's first mission, he displays great power and gets cocky as he is fighting monsters. X.A.N.A. sees his power and uses the Scyphozoa to successfully possess him and makes him go to the Core chamber. He stands at the head of a Creeper attack force focused on the Core of Lyoko. With their combined firepower, the monsters take out the shields layers one by one. Despite their efforts, they fail to stop William from destroying the Core of Lyoko and X.A.N.A. seemingly puts an end to their interference once and for all. In the Digital Sea, William's virtual form floats in an empty limbo and is transformed by X.A.N.A. into a darker version of himself.

Season 4

12 hello handsome

X.A.N.A.'s newest warrior.

X.A.N.A. has created a network of Replikas in the world network to fulfill its ambitions and has a Lyoko Warrior bound to its service when it retrieved William Dunbar from the Digital Sea. X.A.N.A. still fights the Lyoko Warriors to stop them hunting it down on the network, by continuing to target them, the Supercomputer, and their virtual ship. But, is now mainly focused on taking out Franz Hopper who hides in the Digital Sea. It deals with him by trying to capture Aelita and throwing her in, waiting for him to expose himself to save his daughter.

In the starting episode, X.A.N.A. sends William to Earth through the Scanners, which is possible without activating a Tower. He is sent after the group recreated Sector 5. William acts normal, then reveals that he is X.A.N.A.'s slave when he kidnaps Aelita. William virtualizes himself and Aelita into Sector 5, and takes her to an empty Desert Sector to throw her into the Digital Sea. When Odd saves her, William dives in to run back to his new master.

In Double Take, William takes control of Jeremie's activated Tower for X.A.N.A. to use it. Jeremie uses a Tower to create a clone of himself for his own uses and knows how to protect his Towers from being taken over this time. But, X.A.N.A. has given William his own ability to affect towers, which he uses to influence the tower. They both fight for control, but William eventually overpowers Jeremie's defenses. X.A.N.A. has the Jeremie clone attack the group and William guards the Tower with monsters until they deactivate it.

X.A.N.A. creates a polymorphic spectre to kidnap Aelita in Opening Act. It takes the appearance of Chris, the Subdigitals' drummer, and sends her to William on Lyoko. Jim and Chris end up fighting the spectre while the rest of the group deactivate the Tower.

X.A.N.A. takes control of the group's William clone in Wreck Room. Jeremie tries to use a program to free the real William, but it malfunctions and bugs up files in the Tower that generates their William clone. This makes it vulnerable to X.A.N.A.'s influence and prevents deactivation. It takes control and the clone gets more aggressive and eventually attacks the group. They fix and deactivate the Tower in time.

While Jeremie constructs their virtual ship, X.A.N.A. attacks it in Skidbladnir. It sends monsters and William to the new and reprogrammed Sector 5 on a mission to destroy the ship before it is fully constructed. The assault was only narrowly thwarted in the end.

Kongres

New monsters, Kongres.

In Maiden Voyage, the group give their ship its first test run going into the Digital Sea. Their navigation is disabled during the trip, and they stumble upon a new virtual world in the network. X.A.N.A. introduces its new sea monsters in the Digital Sea to attack them, called Kongres.

X.A.N.A. attacks with a spectre as Jeremie teaches Ulrich, Odd, and Yumi to operate the Supercomputer in Crash Course. It knocks Jeremie out cold, leaving them unable to rely on him this time, and goes to capture Aelita to send her to William and a few monsters. They warn Aelita, defeat all of the enemies, and deactivate the Tower on their own without Jeremie's help.

X.A.N.A. counterattacks as the group investigate one of its Replikas that they discovered in the episode Replika. It contains a small virtual world that consists entirely of the Forest Sector. Megatanks arrive to try and destroy their ship, which is their only connection to the Supercomputer. William also appears for a chance at capturing Aelita. They finish their mission in the end.

In I'd Rather Not Talk About It, X.A.N.A. once again targets the Core of Lyoko. It possesses a wild pig to attack the group in the forest, and sends monsters and William to destroy the Core. X.A.N.A. also renders the activated Tower invisible as a trick to confuse them.

In Hot Shower, X.A.N.A. attacks with a meteor shower. It takes control of a military satellite again, so it can use its laser to split a passing comet into shower chunks that will rain upon the Earth, aiming the bulk of them directly at the Factory to destroy the Supercomputer. X.A.N.A. also traps the Skidbladnir in a firewall, so it can capture Aelita when the Skid loses power and disintegrates at sea. They escape and try to deactivate the Tower, but they are occupied by monsters and William. Jeremie tries to hack the military satellite with Yumi's help to try and destroy the meteor, but X.A.N.A. is a flawless program while Jeremie is only human. Aelita takes a risk by having Odd devirtualize her, sending her back to the Factory where the meteor will hit. She gambles that X.A.N.A. wouldn't risk her death, because it needs to capture her alive. Her theory is proven right as X.A.N.A. destroys the comet with the satellite laser, saving the city, and giving up on its attack.

It targets the group and the Skidbladnir in The Lake. Everyone but Yumi goes on a trip to a small island, where Jeremie can't connect to the Supercomputer. X.A.N.A. creates a lake monster from a spectre that projects lightning bolts to anyone coming near the water, while sending the Scyphozoa to drain the Skidbladnir's energy. It also sends William to protect the Tower. X.A.N.A.'s monster attacks the island with more intense lightning bolts, which eventually creates a lightning storm that will incinerate everything on the island. Aelita activates the Skid's shield defense program to destroy the Scyphozoa and stops the attack in time.

Bragging Rights robot spider image 2

X.A.N.A.'s robotic spiders.

In Lab Rat, X.A.N.A. protects the supercomputer that holds its Forest Replika from the group. Jeremie uses a "teleportation" process to send the group to the Replika's location in the real world. They connect the Skid to a Tower, and he sends them to the laboratory in the Amazon jungle that holds the supercomputer. While inside, they learn that X.A.N.A. has possessed scientists making cybernetic spiders. William takes out the warriors guarding the Skid, then enters and inputs the X.A.N.A. code into the tower's interface. This allows X.A.N.A. to take control of the tower and disconnect their ship, severing their link to the facility. The group is left with no choice but to retreat and abort the mission.

They set out to complete their unfinished mission in Bragging Rights. X.A.N.A. activates a Tower to use the cybernetic spiders to deal with the teleported heroes, while it sends William and monsters after the Skid. Ulrich destroys the power supply, which starts to make the sector disappear, but a backup generator activates and regenerates the Replika. William comes back and monsters fire on the Skid. Odd ultimately defeats William single-handedly, takes out the spider robots, and destroys the supercomputer all by himself.

In A Lack of Goodwill, William materializes himself from a Scanner while the heroes are busy infiltrating the next Replika, who is sent by X.A.N.A. on a mission to destroy the Supercomputer down below. However, the William clone shows up with Milly and Tamiya. The clone and the original fight each other, forcing the latter into the elevator. William instead goes to the lab interface in order to mess with the system. William uses the interface to shut off the Scanners, get rid of the clone, and shut down the Supercomputer's cooling system to make it overheat and melt down. X.A.N.A. sends new Shark monsters in the network to delay the Skid. William restarts the Scanners to retreat back to Lyoko. Aelita stops the overheating process in time and saves the Supercomputer.

Distant memory

X.A.N.A.'s minions prepare to target Franz Hopper.

X.A.N.A. lures Aelita to Lyoko by tricking her in Distant Memory. It pretends to be Franz Hopper and sends her an electronic message, saying that he is expecting her on Lyoko, then her computer suddenly bugs up. Aelita goes and enters a Simulation Bubble containing a replication of Aelita's childhood home. By noticing that her mother wasn't programmed into the simulation, she quickly learns this is a X.A.N.A. trick. William was waiting for her inside to capture her. X.A.N.A. tries to trap her inside the simulation bubble, but Aelita uses Creativity to disperse it. The Lyoko Warriors try to protect Aelita, but William succeeds in throwing her into the Digital Sea. But suddenly, she is lifted from the sea by the real Franz Hopper, who appears as a floating blue bubble. William and the monsters are focused on eliminating Franz Hopper, but don't succeed. The group now realize why X.A.N.A. wants to throw Aelita into the Digital Sea. It knows it's the only way to get Hopper to expose himself.

X.A.N.A. counterattacks on the group's second trip to the Desert Replika in Hard Luck. At the military base where the supercomputer is located, X.A.N.A. activates a Tower to teleport Kankrelats into the real world to counter the intruders. In the facility, it has put an assembly line that makes motherboards and electronic implants. The team seemed to be suffering a crippling bug during their mission. In spite of their bad luck, Ulrich manages to take out all of the Kankrelats and destroy the supercomputer by himself.

Hard Luck Kankrelat hits fan image 1

Teleported monsters defending the Replika.

X.A.N.A. attacks when Jeremie rides in an armed fighter jet in Guided Missile for winning a contest. X.A.N.A. possesses the jet in order to use its weapons to target and destroy the Factory and the Supercomputer with it. X.A.N.A. also forces the jet to crash to get rid of Jeremie too. Ulrich defeats William and sets Aelita free to stop the attack and launch a return in time.

In Kadic Bombshell, a glitch is created in the Supercomputer because of Odd bringing someone into the lab. The glitch causes problems with virtualization. Aelita goes in to check for pulsations and activated Towers like in the old days, but this puts her in the crosshairs of X.A.N.A.'s minions. It sends monsters and William to capture her and fight her friends, and William gets overjoyed after hearing they could disappear forever if their defeated them before Jeremie can fix the program. Jeremie fixes it in time and William pushes Aelita over the edge, but Odd saves her.

In Canine Conundrum, X.A.N.A. possesses Jeremie's robot dog in his room, and gives it the ability to replicate multiple copies of itself to attack the school. William and Tarantulas appear to guard the activated Tower on Lyoko. Aelita tricks William with a clone of herself, and gets to the Tower while he is distracted.

Spiked orbs

X.A.N.A.'s spiked orbs.

X.A.N.A. fights the group on the next discovered Replika of Sector 5 in A Space Oddity, which is a copy of Sector 5 and its supercomputer is on a newly built space station orbiting Earth. X.A.N.A.'s purpose for taking it over is to manufacture small, metal spheres that grow spikes and burn through metal. Meanwhile, X.A.N.A. activates the Replika's defense mechanism, which charges a mass of energy that threatens to wipe out the Skid. Ulrich stops the mechanism by pressing the sector's key. X.A.N.A. uses the spheres to attack the ones who are on the space station. Odd and Yumi sabotage the supercomputer by breaking cooling pipes and short-circuiting it with water, completing their mission.

X.A.N.A. tries to destroy the Skidbladnir while at sea in Cousins Once Removed. While Jeremie leaves a program for the shields running on his dorm computer, Sissi and Herb mess with it and unknowingly endanger them in the middle of a battle. Jeremie puts up a firewall, after which X.A.N.A. possesses Sissi and Herb to take over their meddling. It unleashes the Kalamar monster to attack the ship, while its pawns break through the firewall and disable shields and weapons. Jeremie cuts power to the building, cutting off Herb's connection to the Supercomputer and restore their defenses. They destroy the monsters and deactivate the Tower.

In Music to Soothe the Savage Beast, X.A.N.A. kidnaps Aelita again by possessing her show manager, and sends her to Lyoko, surrounded by monsters and William. It also possesses Milly and Tamiya to delay the group backstage at the concert. They save Aelita and deactivate the tower.

X.A.N.A. uses the Scyphozoa to control Aelita again in Wrong Exposure. It takes control of Principal Delmas to kidnap Aelita and virtualize her alone on Lyoko, then has the Scyphozoa possess her mind to make the brainwashed Aelita walk into the Digital Sea. Jeremie activates a program he made earlier to reboot everything inside of the virtual world and break her possession.

X.A.N.A. attacks the group at school in Bad Connection. It uses the school's cell phone antenna to spread a virus to everyone's cellphone, turning anyone who answers them into crazy and violent people. It uses monsters to guard the Tower, and throws a bug into the virtualization program to make things harder for the group. Aelita deactivates the Tower in time.

Kolossus Code Lyoko

The mighty Kolossus.

X.A.N.A. fights the heroes in the next Replika in Cold Sweat. This new Replika is an Ice Sector copy and its supercomputer is located in a lab in Siberia. In this facility, X.A.N.A. is storing brains in test tubes for an unknown purpose. William gets teleported to the base by X.A.N.A. to deal with the intruders. Aelita enters the Tower that commands his teleportation, but then she realizes that the Tower should contain the programs that X.A.N.A. uses to control William. She hacks into the Tower's data and transmits it to Jeremie. After deactivating the Tower, William comes back to the Ice Sector Replika. When he is dispatched by the group, X.A.N.A. suddenly draws on the power of all the Replikas that it controls to create its most powerful and ultimate monster: "the Kolossus," a massive creature that resembles a fire elemental with a sword for a hand. It easily devirtualizes Aelita and Ulrich, and almost destroys the Skid.

ArcticRobots

X.A.N.A.'s robot army.

In Down to Earth, X.A.N.A.'s plans for the world are revealed, and the group breaks William free from its control. Jeremie imagines a program for freeing William for good using the data gathered from the previous episode. They go back to the Ice Replika, in which they discover dozens of humanoid robots lined up like an army at the base. Jeremie realizes that its plan is to create an army of robots to take over all of humanity. X.A.N.A. activates the robots stationed at the base, and sends them after Odd and Aelita. William appears in the Replika and goes into the Digital Sea, but comes back up with the Kolossus. Jeremie tries to immobilize the Kolossus, but breaks free and takes out Yumi. The Kolossus to stomps on Ulrich. Aelita is sent back to the Skid unconscious, and the Kolossus moves toward the ship. It seemed that X.A.N.A. had won, but William is devirtualized by Odd, freeing him from X.A.N.A.'s control, and comes back to normal in the Scanners. With one blow, the Kolossus strikes the Skid into the Digital Sea, but Aelita was devirtualized in time. X.A.N.A. may have lost its most dangerous warrior, but it hardly matters. It is now at the peak of its power, controlling hundreds of Replikas and built a massive robot army prepared to take over the world.

XANA dying

X.A.N.A. being destroyed by Jeremie's own evolved multi-agent program.

X.A.N.A. has its last battle with the Lyoko Warriors in Fight to the Finish. Franz Hopper arranges a meeting on Lyoko for the group just when Jeremie finishes his multi-agent program for wiping out X.A.N.A. for good. Knowing they plan its ultimate demise, X.A.N.A. activates a Tower to possess William, making him its slave again, to knock out Jeremie and unplug the Scanners. It also sends the Kolossus and a few Mantas to destroy the Lyoko Warriors and Franz. Yumi gets herself devirtualized to fight William in the real world. Jeremie sends the Transport Orb for Odd and Aelita, because the program has to be activated from Sector 5. Ulrich managed to defeat the almighty Kolossus, but the giant's body falls on him, devirtualizing him. At the Celestial Dome, they try to run the program, but the energy requirements are too great. Mantas are sent to attack, and Franz Hopper appears and uses his remaining strength to power the program while bearing their lasers. Aelita launches the program, but to her horror, her father is destroyed right in front of her eyes. The program launches a powerful energy force from the Core of Lyoko which seeks and destroys all monsters and spreads to all the sectors of Lyoko, including the activated Tower. X.A.N.A.'s spectre is forced out of William and writhes in agony. The multi-agent program exits Lyoko's floodgate and into the world network, it destroys all of X.A.N.A.'s Replikas on the net. X.A.N.A. screams in agony as its spectre in the real world is erased from existence as the Tower deactivates. Every trace of X.A.N.A. everywhere on the network has been completely annihilated, ending the threat of X.A.N.A. forever.

Other Continuities

Evolution

Xana returned

A Tower activated, signifying the rebirth of X.A.N.A..

In the live-action Evolution sequel, X.A.N.A. has revived, stronger than ever, through an unknown Replika called the Cortex. X.A.N.A. had injected its own Source Codes into the warriors in their last battle. It hides from the inventor of the Cortex, and sends spectres to Earth and take its source codes back, so it will become powerful enough to gain complete control of the entire world network.

X.A.N.A. resurfaces in the starting episode, X.A.N.A. 2.0. It makes strange computer bugs and short circuits occur at the school, which compels the group to reactivate Lyoko to see if their old enemy has returned. A Tower activates and monsters start attacking. On Earth, it creates a spectre with Jim's likeness, and it suddenly grabs Ulrich and he starts getting very weak and ill. The group stops the attack.

In the episode Cortex, when the group reprograms the Skidbladnir and enter the Cortex, X.A.N.A. sends Krabs to stop them from accessing the core, but is met with failure.

In Spectromania, X.A.N.A. sends a kid spectre to steal source codes. It manages to touch Aelita, Yumi, and Odd before the Tower was deactivated, but this was a ruse to hide a second activated Tower whose signal was masked by the first, which generates another spectre in Ulrich's form. Odd gets to Lyoko and deactivates the second Tower. X.A.N.A. has gotten back about 70% of its source codes now.

X.A.N.A. battles the group in Miss Einstein when they test drive their new Megapod vehicle inside the Cortex. With the help of Laura Gauthier, the group is saved.

In Rivalry, X.A.N.A. sends a spectre in the form of William and touched Yumi before it was discovered. On Lyoko, it sends three Tarantulas, making one of them invisible. Odd deactivates the Tower, but with its power at 75%, it is strong enough to relaunch another attack immediately. It disrupts the telephone network with a virus, rendering cellphones unusable. William and Ulrich cooperate together and deactivate the Tower.

In Countdown, X.A.N.A. creates a polymorphic spectre to infiltrate the school and steal source codes. It touches Odd, and the event gives him speech problems as a side effect. On Lyoko, it creates a wall of Bloks to block their access to the Tower. The spectre planned to take all of their codes in one fell swoop when they all arrive at the lab. Odd defeats the Blok Wall and deactivates the Tower before the polymorph could touch them. X.A.N.A. has now recovered 80% of its strength.

In How to Fool X.A.N.A., X.A.N.A. sends a spectre with hypnotic abilities after Yumi. At the time, Jeremie injects false source codes inside of Ulrich that will destroy any spectre that tries to take them. However, X.A.N.A. discovers this plan thanks to a bug that it planted. Ulrich touches the spectre and implants it with the fake codes, which destroys it before it touches Yumi. This causes X.A.N.A. to lose some of its source codes, which are likely transferred back to Ulrich.

In Rendezvous, X.A.N.A. creates a spectre of Anthea Schaeffer, Aelita's mother, to take advantage of her feelings. On Lyoko, it uses two Towers that activate and deactivate in sequence to prevent the heroes from thwarting its scheme. It asks her to meet at the chapel through a message. They share a hug, in which the spectre touches her and steals her codes. Laura figures out the sequence and finds a window that allows Yumi and Odd to deactivate the Towers before Aelita loses all her codes. X.A.N.A. is at 80% power.

In Chaos at Kadic, X.A.N.A. activates a Tower from the Cortex to put a virus in the school's computer system, messing up test scores among other problems. They destroy the monsters, and Yumi deactivates the Tower.

In Friday the 13th, X.A.N.A. infects the Skidbladnir with a devastating virus. It activates a Tower in Sector 5 to cause lottery wins to happen all over the country as a diversion to buy time for the virus to be uploaded. Odd gets the infected ship out of Lyoko, and counters the virus with Laura and Aelita's help.

Confusion49

An army of monsters fighting Tyron's ninjas.

X.A.N.A. seems to malfunction in Confusion. It keeps activating and deactivating Towers, causing spectres to emerge and disappear in moments, and its monsters instantly devirtualize. In the Cortex, an army of Krabs and Tarantulas fight against Tyron's ninjas in the core, and attack the Lyoko Warriors as soon as they arrive. It is revealed that a security update made by Tyron in the Cortex was the source of its interference, which it destroyed in the battle. This reveals to the group that Tyron has no idea that X.A.N.A. hides in his supercomputer.

In The Codeless, X.A.N.A. sends a spectre in the form of a football player which goes after Odd and steals the last of his source codes. It is now up to 85% power and activates another Tower soon after, sending a spectre with the same appearance as the last one. Yumi and William go after the Tower, but they are confronted by a virtual clone of William created by X.A.N.A., who plays on his doubts about his place on the team. William overcomes his feelings and turns on the clone, allowing Yumi to deactivate the Tower.

The group complete their virus to inject into the Cortex in Obstinacy. X.A.N.A. sends monsters to stop them, including Mantas that can now operate in the Digital Sea. When Aelita sees her mother in Tyron's lab through the webcam, they stop their plan.

The Trap (Evolution) 13

A spectre on Lyoko.

X.A.N.A.'s spectre gets caught in a trap by the group in The Trap. Jeremie plans to get source codes back from spectres, in which they create a situation were Yumi lures a spectre into a Scanner, and it works. Jeremie steals 4% of X.A.N.A.'s own codes through the spectre. It tries to escape, damaging the rest of the Scanners in the process. The spectre explodes inside and its residue gets virtualized as a living particle cloud. It puts Yumi and Ulrich into comas with its touch. Since the spectre was made to steal codes, it ignores the codeless Odd. With no codes in the virtual world, the spectre drags the unconscious Yumi to the Digital Sea. Jeremie transfers the source codes he has stolen to Odd, but they now compel the spectre to chase after him. Odd gets into the Tower, and enters the Lyoko code before it touches him. X.A.N.A. lost 4% power, and Odd is no longer codeless.

X.A.N.A. attacks using clones to confuse the group in False Pretenses. It sends a polymorphic spectre that shape-shifts into each of the Warriors to steal source codes, and creates perfect clones of them in the virtual world, confusing them. Jeremie and Laura launch a program to make the clones glow, allowing the real ones to devirtualize the fakes, and deactivate the Tower.

XANA-William

William held by the Scyphozoa.

In Mutiny, X.A.N.A. takes control of William again. Laura and William decide to act on their own to plant their virus immediately. They enter without much trouble, but he is then surrounded by Krabs. The Scyphozoa appears and implants its tentacles into his body, turning him into X.A.N.A.'s pawn once again. X.A.N.A. has the Scyphozoa hold him in its grasp the entire time, trying to steal their virus when it gotten uploaded into himself. The possessed William commands an army of Krabs and fights the group. Ulrich distracts him long enough for his tentacles to be cut, turning him back to normal.

In Jeremy's Blues, X.A.N.A. sets a clever trap for the group. Jeremie sends Ulrich and Odd in the Skid to investigate a data packet sent by an unknown source in the Digital Sea. Then, the ship gets caught in a trap. X.A.N.A. sends five Sharks to destroy the ship and the trap damages the holoweb, leaving them helpless. Aelita gets the two back to Earth, but the Sharks destroy the Skid. This incident has left both the holomap and the Superscan badly damaged. X.A.N.A. attacks with a spectre in Mrs. Hertz's appearance and sends Kankrelats that duplicate to hold back William and Yumi. The spectre gets some of Aelita's source codes. Jeremie quickly fixes the holomap, and they deactivate the Tower. X.A.N.A. is at 92% power now.

X.A.N.A. uses another spectre for a particularly offensive attack in Massacre. It sends a spectre in the form of Mr. Rouiller, while Yumi and Aelita are on a mission inside of the Cortex. The spectre steals Odd's codes. X.A.N.A. has eight Bloks guard the Tower, and Megatanks and Krabs attack Aelita and Yumi. The spectre steals Ulrich's codes also. Aelita escapes and arrives on Lyoko to take out the Bloks. Aelita deactivates the Tower before the spectre takes Yumi's codes. X.A.N.A. has rendered Ulrich and Odd codeless, and is up to 95% full power.

Cortexball dissapearing

The disintegration of the Cortex, where X.A.N.A. now lives.

In the final episode, the Lyoko Warriors are forced to implant their virus immediately which would wipe out Tyron's supercomputer, and X.A.N.A. with it. During their first attempt, X.A.N.A.'s current power level allowed its Mantas to destroy the Megapod and the whole group in mere moments, forcing them to wait twelve more hours to try again. They suffer interference from Tyron in the real world, but they succeed in entering the core. Tyron shuts down his supercomputer to avoid losing all his data as they planted the virus. Unless Tyron finds an antivirus, X.A.N.A. will be rendered eternally frozen as long as the Cortex stays turned off. If Lyoko stays active, it will still have a way of escaping, so the group shuts down their own supercomputer, but will remain on their guard if it turns out X.A.N.A. survived again.

Chronicles

In this alternate continuity, the events of the first four seasons are severely streamlined as the first book indicates. While the events of the prequel and the first season are followed relatively the same as before, the climax of the rest of the series is compressed into one event. Franz Hopper reveals himself to the group before any equivalent of The Key occurs. He informs the group how to destroy X.A.N.A., by launching the multi-agent program into the Core of Lyoko. Hopper sacrifices himself to provide the energy needed, while at the same time restoring Aelita's memories and informing the group about her mother.

As for X.A.N.A., the entity's core is destroyed. It is purged and ejected from Lyoko, left to drift in the network without its memories or core functions. Over the course of several months however, X.A.N.A. begins to gain strength back, and searches for a human vessel in lieu of a virtual world. Ultimately, it looks for a vessel that it can use to infiltrate Kadic without suspicion, so as to kill the Lyoko Warriors.

Choosing a girl known as Eva Skinner, X.A.N.A. began to settle into its new circumstances, and learned of the Lyoko Warriors researching the history of the Supercomputer. Seeing a chance to gain its strength back, X.A.N.A. befriended the group, but planned on destroying them from the inside out. Over a time period, it gradually gained enough trust that they "informed" Eva about the supercomputer, Franz Hopper, and their search for Anthea Hopper. Seducing Odd, X.A.N.A. managed to brainwash the boy, laying the groundwork for its return.

X.A.N.A. however, would later learn from Hopper's archives multiple shocking truths: that he had been made with altruistic purposes in mind, to be the Guardian of Lyoko and the First City. Moreover, he had been close friends with Aelita, a friendship Hopper encouraged as a way to teach him human emotions. However, he forgot about all this when he was corrupted by leftover coding from a dark zone program, Project Carthage, whose templates Lyoko had been created from.

Shaken by this, as well as the emotions that had gradually crept up on him the longer he stayed in the Lyoko Warriors' company, X.A.N.A sought out an opportunity to speak to Aelita alone and share what he'd remembered. While rightfully wary of the AI, whose identity had by now been ousted, she nevertheless agreed. Appearing to her as a young man greatly resembling William, X.A.N.A spent many hours talking with her. But though they rekindled their former friendship, the discussion ended in conflict when X.A.N.A. mistook her reluctance to help him as a declaration of war. Leaving her, he began preparations to dominate the world.

Aelita, not giving up, pursued him. She persuaded him to listen to his original programming and fight off the virus still infecting him. X.A.N.A. would thus ally himself permanently with humanity, helping the Lyoko Warriors to defeat a terrorist group that was hoping to use Lyoko as a substitute for Carthage. While X.A.N.A. seemingly sacrificed himself to upload a self-destruction program that would delete Lyoko for good, his programming was salvaged by Aelita, who managed to recreate X.A.N.A. and bring him into the real world as a human.

Abilities

VIRUS Logo

X.A.N.A.'s eye symbol indicates its presence.

X.A.N.A. is a computer program that is highly intelligent, performs flawless calculations, and controls forces beyond any machine on Earth. It keeps a hidden presence inside the Supercomputer. X.A.N.A. was originally bound to the machine, but escaped into the world network with the Keys to Lyoko stolen from Aelita. Its capabilities are listed below:

Tower Control

Tour carthage-1-

X.A.N.A. activating a tower.

X.A.N.A. can activate Towers on Lyoko, signified by pulsations. It can take over unprotected Towers used by others, and use many for advanced computing. The only way to stop them is by deactivating the Towers.

To act on Earth, X.A.N.A. sends digital impulses that travel around networks as manifestations of its power, generates spectres from outlets that can affect the real world, or polymorphic spectres that appear as clones of people or shapeshifters. When its Towers deactivate, these effects are negated and disappear. X.A.N.A. can channel abilities through these forms listed below:

Xana spectre

A spectre emerging.

X.A.N.A.'s main ability is to possess and manipulate objects (machines, natural forces, plants, animals, etc.) like a virus that it uses to launch attacks on Earth. The Eye of X.A.N.A. signifies its control. It can control and modify them at the atomic level to make them more dangerous. X.A.N.A. later grows powerful enough to possess humans to do its bidding, and pixelize them to channel abilities through them, like spectral bodies, inhuman strength and speed, electromagnetic powers, etc. Only Lyoko Warriors cannot be controlled. The affected return to normal when their Towers deactivate and humans do not remember anything.

X.A.N.A. can also control electromagnetic forces from its manifestations to many effects. It can manipulate electricity, create short circuits in networks, harness ultrasound waves to cause earthquakes, magnetic fields to alter gravity and levitate objects, and cast viruses onto humans directly.

Other abilities include materializing real monsters or clones through the Scanners, teleporting minions, activating special devices it has built, or stimulating minds with psychic visions through a shared link.

Monsters & Programs

XANA Monsters

X.A.N.A.'s monsters

X.A.N.A. uses monsters to fight in virtual areas. They include Kankrelats, Bloks, Hornets, Krabs, MegatanksTarantulas, Creepers, Mantas, Kongres, Sharks, and the Kalamar. They are mostly armed with Lasers. It also created the Scyphozoa, a monster made to steal memory from anything, drain life energy, or plant its virus to control Lyoko Warriors.

Using other programs, X.A.N.A. can alter landscape, use virtual weather, illusions, false data, and virtual prisons like Guardians, Simulation Bubbles, or network firewalls, launch programs through monsters, and use bugs and viruses. X.A.N.A. can also manipulate the exposed code of incomplete or lost warriors to steal their memory, possess them, or bind their essence to its program. It can also program upgrades, weapons, and vehicles for them.

Replikas

A Replika

Once it has accessed the world network, X.A.N.A. has spent its time creating Replikas, small copies of Lyoko, to take over supercomputers and facilities on Earth to build electronics, weapons, and robot armies to conquer the world. To counter intruders, X.A.N.A. activates Towers to possess humans, activate its weapons, or teleport minions.

Furthermore, X.A.N.A.'s network of Replikas gives it greater computing power in virtual worlds. With this extra power, it can create the mighty Kolossus, a massive, fiery giant that can dominate conventional battle. Its immense strength can tear apart the landscape, instantly devirtualize enemies, and destroy the Skidbladnir in a single moment. It is invulnerable to attack, except for the eye symbols on its head and arm, which both need to be hit.

Trivia

  • X.A.N.A. was voiced by David Gasman in Ghost Channel, in the American version of Code Lyoko, the same actor who also voices Herb, Jim, and William.
  • According to YTV's Vortex block's host Paula (Code Lyoko was a show on this block and during commercial breaks Paula would often share bits of trivia), X.A.N.A. was once a good computer program until an evil virus corrupted it. Interestingly, she said this piece of information in the middle of season one, before season two even aired. No evidence was stated to prove this fact, as it implies that it was Franz Hopper's abuse of the return in time program that made X.A.N.A. evil, not a virus. However, the novel series states that it really was a virus that corrupted it in the end.
  • X.A.N.A.'s name was derived from Xanadu, the virtual world in Garage Kids.
  • Since X.A.N.A. is basically a computer program, it is supposed to be genderless as neither male or female. However, everyone except Franz Hopper constantly addresses X.A.N.A. by male pronouns in the main series. This may be due to all nouns having genders in French, the show's original language. In Code Lyoko Evolution, X.A.N.A. is rightfully called an "it" as genderless in the series.
    • X.A.N.A.'s name is used with male pronouns in Code Lyoko; whereas in Evolution, his name was genderless.
