–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 Code Lyoko. It is an evil computer virus that is a threat to mankind. Its only obstacles are the Lyoko Warriors. It has taken over the Supercomputer that holds Lyoko. By activating Towers, it attacks on Earth and creates monsters, alterations, and traps on Lyoko to fight its enemies.

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


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

X.A.N.A. is a digital entity that is completely without a physical form. It lives as a sentient, electronic force in the machine that merely exists as red, pulsating energies that run through the Lyoko Wires, revealing its presence in the virtual world and the Supercomputer.

The ghostly spectres it generates may as well be its true form in the real world. Even then, they are just extensions that are its means of acting on Earth, while its true self remains safe in the virtual world.

XANA's only physical appearance

X.A.N.A.'s only real incarnation was in Ghost Channel, as a fake Jeremie inside a Simulation Bubble. It manifested its presence into a demonic caricature figure of the false Jeremie, with sharp nails, spiky hair, and an unnatural aura. But, the closest thing to a real appearance was in Fight to the Finish. When X.A.N.A. was being wiped out across the world network by Jeremie's multi-agent antivirus, the spectre that was using to control William was forced out and became a giant, formless being with its eye symbol on the chest, screaming and writhing in agony before it disappears.


X.A.N.A. is a sentient computer virus, becoming a chaotic and destructive enemy force. Its computing intellect can build technology, calculate attacks, and even predict human behavior. However, it is bound by logical patterns that make it very predictable. Among its vessels, X.A.N.A. has the simple mindset of an inhuman, hostile force with some intelligence. It is violent, ruthless, sadistic, manipulative, and egomaniacal when having the advantage. Its knowledge of humans is purely theoretical and never repeats the exact same plan twice.

Its goals and desires evolve as the series progresses. At first, X.A.N.A. simply attacks humanity and its mortal enemies at random to eliminate its obstacles and survive. As its intelligence grows, it wants to increase its power and steal the Keys to Lyoko from Aelita. With the keys, X.A.N.A. escapes the Supercomputer and takes over the network, by infecting supercomputers with Replikas to build weapons and robot armies to conquer the world.

Being logical, X.A.N.A. would put its goals and survival above destroying its enemies. It would quickly spare them from certain death for its larger plans or team up with them against a bigger threat to survive.

Character Relationships

Lyoko Warriors

The Lyoko Warriors are X.A.N.A.'s mortal enemies throughout the series. While usually targeting them physically, X.A.N.A. has occasionally infiltrated the group through either clones or possession in an attempt to sabotage their social dynamic from within, utilizing and manipulating emotions of jealousy, betrayal and flattery to varying degrees of success.

It also has separate opinions to describe each and every one of them:

  • Jeremie Belpois: X.A.N.A. sees Jeremie as the biggest threat, thinking he would eventually become as smart as its creator and would figure out his work. Also, X.A.N.A. has the most respect for him such as when it made a spectre in his exact likeness, it said that it was "almost proud to resemble him."
  • Aelita Schaeffer: Through the series, X.A.N.A. has treated Aelita as a target, a hostage, a tool, and a lifeline. It wishes to control Aelita, given how it constantly needs her to further its plans, but frequently underestimates her drive and willpower.
  • Yumi Ishiyama: X.A.N.A. seems to target Yumi more than the rest of the group, as her typical loner status makes her the most vulnerable. She is usually only able to survive by endurance alone.
  • Odd Della Robbia: X.A.N.A. sees Odd as the most childish of the team. It even subtly mocked him, when its polymorph took his appearance after he suggested that it "turns into a wimp."
  • Ulrich Stern: X.A.N.A. knows Ulrich is the best fighter of the group, and as such targets him frequently. It usually fights by outnumbering him on Lyoko.
  • William Dunbar: It witnessed William's superior abilities during his first time on Lyoko, and used the Scyphozoa to put him into its grip, making him into a powerful weapon to use against its enemies and advance its plans.
  • 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. X.A.N.A. barely learned anything about Eva's social life during its time possessing her, as it was instead far more interested in the social structure of humanity itself.

Franz Hopper

As X.A.N.A. knows that Franz can bring about its destruction, it is bent on taking out its creator. X.A.N.A. fears him the most, and he is the reason the Lyoko Warriors keep coming back from their defeats. Its need to destroy Hopper takes priority over killing the Lyoko Warriors. In Hot Shower, it was willing to spare them from certain death, because it needs Aelita as bait to draw out Hopper.

Powers and Abilities

X.A.N.A.'s presence on a screen

X.A.N.A. is a powerful computer virus that can inhabit and take over systems, like the Supercomputer to exploit its capabilities. It is also an entire multi-agent system that sends virus extensions to attack on Earth and inhabit many systems at once.

It was initially bound to the Supercomputer, but after getting the Keys to Lyoko, X.A.N.A. can escape into the network and create Replikas in other machines to survive and conquer the world. Its capabilities are listed below:

Tower Control

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

X.A.N.A. activates Towers, known by pulsations, to act on Earth. The only way to stop them is to deactivate the Towers. With Towers, X.A.N.A. manifests extensions of its virus system that infiltrate or take over networks, or emerge from outlets as spectres, ghostly forms that can interact with the real world.

It has many dangerous abilities, mainly possessing material on Earth (machines, objects, natural elements, plants, animals, etc.) like a virus to manipulate and bend to its will, and causing electromagnetic phenomena to control electricity, affect the environment, and use hypnotic sounds. X.A.N.A. can later possess humans and manifest polymorphic spectres that impersonate people, to serve as inhumanly powered vessels that do its bidding on Earth. Only Lyoko Warriors cannot be controlled. They return to normal or disappear when their Towers deactivate and people have no memory of the events.

With Towers, X.A.N.A. can also materialize or teleport virtual minions to Earth through the Scanners or Replikas, control special devices it has built, or show psychic visions through a unique link.

Monsters & Programs

X.A.N.A.'s monsters

On virtual worlds, X.A.N.A. creates and virtualizes monsters of many types to fight its enemies and attack targets. It also made the Scyphozoa to steal digital memory and energy, or possess warriors on Lyoko. With its Replikas, X.A.N.A. can send the titanic Kolossus, its biggest and most powerful monster.

It is also capable of altering virtual environments, casting illusions, and opening portals, creating virtual prisons, planting bugs or viruses, manipulating incomplete warriors, and creating equipment and vehicles on Lyoko.



X.A.N.A. and Lyoko were created by a scientist named Franz Hopper, formerly Waldo Franz Schaeffer, to destroy Project Carthage. Franz also discovered the time reversion function to have all the time he needs to build Lyoko. With each one, X.A.N.A. grows stronger, showing signs of self-awareness. With the Scanners and virtualization programs ready, Franz Hopper and his daughter fled to Lyoko to escape the men in black. X.A.N.A. then betrays its creator, trapping him and Aelita on Lyoko, so they cannot materialize and tries to kill them both. Franz tries to reason with the sentient virus, but it has become too powerful and a threat to mankind, leaving him no choice but to shut down the Supercomputer.


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

X.A.N.A. was reawakened in the X.A.N.A. Awakens prequel by Jeremie, when he turns on the Supercomputer and discovers Aelita and Lyoko. X.A.N.A. sends monsters after Aelita and activates a Tower, controlling devices and generating electricity to attack all those involved with Lyoko. Jeremie sends Odd, Ulrich and Yumi to Lyoko to fight the monsters and ensure Aelita deactivates the Tower. The group decide to let Jeremie keep working on materializing Aelita, knowing they can neutralize X.A.N.A. by deactivating the Towers, becoming the Lyoko Warriors.

First Encounters

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

While Jeremie works on materializing Aelita, X.A.N.A. randomly attacks on Earth to eliminate the Lyoko Warriors. Through activated Towers, the deadly virus takes over networks, causes electromagnetic phenomena, or possesses material or animals to bend to its will. X.A.N.A. also sets traps, imprisons warriors, and materializes creatures from the Scanners.

When Aelita's materialization program is complete, X.A.N.A. tries to stop them from using it, knowing they will shut down the Supercomputer afterward. It has monsters attack the Tower they need to run the program. It doesn't succeed, but X.A.N.A. takes a fragment from Aelita to bind her to Lyoko. After Aelita was materialized, Jeremie discovers the alteration, but mistakes it for a virus inside her. When they shut the machine down, she goes into a lethal coma, but wakes up when turned back on. This alteration has ensured X.A.N.A.'s survival for now.

Growing Power

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

X.A.N.A. is growing smarter and more powerful, learning to create new monsters on Lyoko, displayed by its new Tarantulas. Aelita discovers the Hermitage in the forest and is haunted by mysterious visions. X.A.N.A. sends a spectre to kidnap Aelita and possess the house to lure its enemies into a steam room to be boiled alive. Even with two Tarantulas on guard, the group save their friends.

No longer attacking at random, X.A.N.A. learns to anticipate its enemies and think of bigger plans. While still it tries to kill its mortal enemies, X.A.N.A. now wants to escape the Supercomputer and access the world network. To gain its freedom, X.A.N.A. must steal the Keys to Lyoko inside Aelita's memory. It creates the Scyphozoa which can steal memory and life energy to take the information from her mind. X.A.N.A. launches attacks and schemes to lure her to Lyoko (kidnapping, misdirection, brainwashing, deception, etc.) and make sure no one interferes during the process. Until it gets her memory, it has to be careful to keep her alive no matter what.

The Scyphozoa stealing Aelita's memory.

The group discovers a fifth sector in Lyoko where X.A.N.A. and all of its data lives, but has Creeper and Manta monsters, mechanical traps, and a countdown procedure to keep out intruders. The team regularly goes there to gather data on the assumed virus that ties Aelita to X.A.N.A.

It is soon revealed that returns to the past make X.A.N.A. stronger. It sets a trap inside recovered data to take over the time returns, repeating the same day until it gains the ability to possess humans with spectres. The team stopped its plan, but X.A.N.A. can now bend people to its will to be pixelized vessels that attack and do its bidding on Earth, mostly to kidnap Aelita to bring to Lyoko or even mess with the lab interface to interfere with the team's missions.

When the group finds Franz Hopper's encrypted diary, X.A.N.A. tries to possess one of the team, but only gets Jeremie. It has him destroy the discs and their secrets, but he copied the diary into the Supercomputer beforehand. This reveals that those who have been virtualized to Lyoko cannot be controlled, so Jeremie gets virtualized to protect himself.

X.A.N.A. helps the group on two occasions. When Jeremie creates the Marabounta to target monsters and went out of control on Lyoko, it sends monsters to protect Aelita and helps the group destroy it to preserve Lyoko and Aelita's memory. The second time was when the Supercomputer's nuclear battery was failing, putting it and Aelita at risk of dying. X.A.N.A. acts by possessing a criminal to steal another and kidnaps Jeremie to make him change the battery, knowing they both have a common interest to keep the machine online. It tries to kill him after the Supercomputer is reactivated and fails.

A polymorphic spectre.

As more proof of its growing power. X.A.N.A. becomes capable of sending Mantas to surface sectors and manifesting polymorphic spectres, pixelated ghosts that take the forms of people. Since it cannot possess any of the group, this allows X.A.N.A. to deceive them by using their identities to sow dissent, trap or ambush the team on Lyoko, or impersonate Franz Hopper to gain their trust.

Later, the real Franz Hopper makes contact by possessing Sissi Delmas to write a message. X.A.N.A. acts by having monsters attack his Tower and possessing a doctor to kill the vessel, but the latter fails. He also helps decrypt his diary and saves them from X.A.N.A.'s plan to steal their data. Following the decryption, the diary reveals that Franz Hopper created X.A.N.A. and Lyoko, but also that Aelita is his daughter and he virtualized her to Lyoko along with himself.

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

The diary has also revealed that Aelita has the Keys to Lyoko inside her, the codes that X.A.N.A. needs to escape the Supercomputer. Jeremie also finds out that she doesn't have a virus, but a missing fragment. X.A.N.A. sets up a fake fragment for them to lure Aelita to Sector 5. Its trap is sprung when falling objects drop from the ceiling that devirtualize her friends, allowing the Scyphozoa to steal her memory with no one left to stop it and causes her to drop lifeless. X.A.N.A. then darkens the virtual world and activates Towers in all four sectors. It manifests its whole being as a massive spectre from the Factory, that escapes into the network.

Suddenly, Franz Hopper takes action to fully restore Aelita and Lyoko, deactivating the Towers, and sending her back to Earth. Aelita is whole again, but X.A.N.A. is also free from the Supercomputer. Shutting the machine down will not stop it anymore and has sinister plans to take over the world.

Targeting Lyoko

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

X.A.N.A. has left the Supercomputer and lies within the network. It hasn't attacked since then, thinking it's out of the group's reach. When Jeremie upgrades the Superscan to track X.A.N.A. in the network, it responds by sending monsters to an unknown room in Sector 5 that contains the Core of Lyoko. They attack its shield layers and try to destroy it, which will wipe out Lyoko as a result. They stop the assault in the end.

Now that X.A.N.A. has left the Supercomputer, it is more dangerous than ever and is capable of more ruthless attacks against its enemies. It now seeks to destroy Lyoko to permanently stop its enemies. X.A.N.A. sends monsters to attack the Core of Lyoko while causing events to keep them away or distracted, even possesses a virtual body to use as a weapon, but they save the core every time. X.A.N.A. also launches attacks aimed directly at the Supercomputer, by having possessed humans sabotage or destroy the machine, or blow up the whole Factory. It continues to fail every one of these schemes.

X.A.N.A.'s code being entered

To lower their chances of stopping its attacks, X.A.N.A. also seeks to destroy surface sectors to block access to the Transport Orb, by possessing Aelita with the Scyphozoa to input its virus code in Way Towers, allowing X.A.N.A. to erase whole sectors one at a time. It succeeds in the order of Forest, Desert, Ice, and Mountain, but Jeremie found a way to virtualize the team directly into Sector 5.

X.A.N.A. transforming William

After the last sector is destroyed, the team decides to recruit William Dunbar. On his first mission, X.A.N.A. sees his power and uses the Scyphozoa to possess him. It has him lead a Creeper army centered around the Core of Lyoko, quickly destroying its shields with their combined firepower. The team finally arrives, but William defeats them all with ease. The possessed William then uses his sword to destroy the core and wipe Lyoko off the network. William was left in the void, but X.A.N.A. retrieves and captures him, binding his digital essence to its program.

Ultimate Plans

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

With data sent by Franz Hopper, Jeremie and Aelita recreated Lyoko, starting with Sector 5 and getting rid of its countdown procedure. Soon after they do, X.A.N.A. sends William to the real world from the Scanners. He acts normal around the team, then kidnaps Aelita to virtualize her and himself to Lyoko, so he can throw her into the Digital Sea for an unknown reason. He doesn't succeed, but shows the group that he is an agent of X.A.N.A. now.

X.A.N.A. has made William its loyal servant and commander. Its possession of him gives him strength beyond any warrior, new abilities and weaponry, command over monsters in battle, a Black Manta to ride, and a copy of its Lyoko keys to affect Towers its master cannot and use their interfaces. X.A.N.A. can also materialize William as a possessed human from the Scanners without needing to activate a Tower.

The evil virus remains determined to kill the group and destroy Lyoko to get rid of obstacles, but has also concluded that Franz Hopper is the greatest threat, as he is the reason they keep surviving their defeats. To draw him out, X.A.N.A. once again targets Aelita, luring her to Lyoko and having William throw her into the Digital Sea, which will compel Franz to save her and put her back on land, exposing himself while protecting her. X.A.N.A. seeks to destroy its creator and the group, knowing if they joined forces, they can surely bring about its destruction.

Inside the Digital Sea, X.A.N.A. has built a network of Replikas, smaller Lyoko copies, in other supercomputers infected with its multi-agent system. They become new territories to survive outside Lyoko and give it control of military facilities on Earth, like a Forest Replika in a jungle laboratory, a Desert Replika in a New Mexico base, and a Carthage Replika in a space station. These places become X.A.N.A.'s own laboratories and factories to build technology and dangerous weapons using possessed scientists or automated machinery, like cybernetic spiders and metallic orb drones, which X.A.N.A. controls through electronic implants. It also built an energy shield generator at the jungle lab and was researching brains in test tubes.

The Lyoko Warriors build the Skidbladnir, a virtual submarine docked in Sector 5. They use it to travel in the network beyond the Digital Sea to discover X.A.N.A's evil schemes and destroy its supercomputers, by teleporting themselves to its real world facilities as Lyoko Warrior spectres to infiltrate them.

Kongre monsters

To stop their interference, X.A.N.A. targets their ship while they explore in the network using new Kongre and Shark monsters, and William using a personal Nav Skid. Inside Replikas, X.A.N.A. attacks the ship while docked using minions or traps, activates Towers to counter the teleported heroes inside its bases, and also has William enter and deactivate their Towers. It also attacks the Skidbladnir with the Scyphozoa or the Kalamar monsters, but continues to fail.

The mighty Kolossus.

When the team infiltrates the Ice Replika, linked to a lab in Siberia, X.A.N.A. teleports William to counter the heroes, but this lets Aelita acquire data on how X.A.N.A. controls William. But afterward, it draws power from all its Replikas simultaneously to reveal its most powerful monster: "the Kolossus." Its overwhelming presence forced them to retreat, and this event reveals X.A.N.A. controls hundreds of Replikas inside of the network.

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

Jeremie creates an incomplete multi-agent program to destroy X.A.N.A. and one to free William, but the latter will only work on the Ice Replika. To deal with the Kolossus, Jeremie uses his incomplete program to immobilize it, but only holds for a moment. Inside the base, the group discover large robots lined up, revealing X.A.N.A.'s secret plan to build an army of robots to take over the world. The group manage to free William from X.A.N.A. using their program, but the Kolossus destroys the Skidbladnir at the end of the battle.

X.A.N.A.'s vast network of Replikas makes the deadly virus unstoppable. It has the Kolossus to take out its enemies on the virtual worlds and built an army prepared to destroy and enslave the entire world. Without the Skidbladnir, the Lyoko Warriors have no means of taking out Replikas. Jeremie's multi-agent program is their only hope of saving the world from destruction.

Final Battle

X.A.N.A. being destroyed.

X.A.N.A. has its last battle when the group and Franz Hopper meet to launch their program. It possesses William to deal with Jeremie and unplug the Scanners, and sends the Kolossus and Mantas to destroy everyone on Lyoko. Yumi fights William, while Odd, Aelita, and Franz launch the program. Ulrich defeats the Kolossus and is de-virtualized. They don't have enough power to run the program, but Franz Hopper provides it at the cost of his life. The antivirus is launched from the Core of Lyoko, which destroys all monsters, then spreads to the activated Tower, the sectors, then all of its Replikas. Its spectre is forced out of William, displaying X.A.N.A. screaming in agony as every part of itself in the network dies. The deadly virus has finally been destroyed and will never threaten the world again.

Other Continuities

X.A.N.A. reappears in the live-action Evolution sequel and the alternate continuity of the Chronicles novel series. It should be noted that neither of the two continuities are completely canon, as Evolution was disowned by the original show-runners, who confirmed that only a few of their ideas made it into the show and that the events within were not canon. Similarly, while the novels were written with the original documents in hand, not all of their events are noted to be canon either.

Code Lyoko: Evolution

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

In the live-action Evolution sequel, X.A.N.A. has survived its demise in the previous series by hiding in the supercomputer that generates an unknown Replika, called the Cortex. X.A.N.A. causes strange bugs in the Kadic school's computers and short circuits, which compels the group to reactivate the Supercomputer and restore Lyoko, renewing their struggle with their old enemy.

Furthermore, X.A.N.A. had injected its own Source Codes into the warriors in their last battle, which contain fragments of its power. It now acts to generate spectres on Earth to focus on stealing back its source codes from the teenagers, and gradually recover its full strength. At the same time, X.A.N.A. also keeps itself hidden from the owner of the Cortex, Professor Tyron, so he does not do anything rash to purge it from his systems.

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

Throughout this series near the end, X.A.N.A. has gradually recovered 95% of its full power from the Lyoko Warriors, but the group have also diligently worked on a virus that would wipe out the Cortex and X.A.N.A. too. They were forced to implant the virus immediately, but Tyron shuts down his supercomputer to avoid losing all his work while the virus was uploaded.

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 escape destruction again, so the group shuts down the Supercomputer, but will remain on guard if X.A.N.A. survives.

Code Lyoko: 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, all this had been clouded 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 by 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 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.


  • 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.
