Specter

Xana — Specter in *Fight to the Finish*.

A Specter^[1] (Spectre in the French version), also referred to as a Ghost, is a digital entity that has been given physical form. They are used as extensions of X.A.N.A. that serve as its means of launching its attacks on Earth, by possessing objects and creating pixelized humans to do its bidding.

Overview

Creating a specter is done by activating a tower, which will send a digital impulse that will travel at hyper-speed through all the networks and gather huge amounts of energy, then guiding it by remote control toward an exit of the programmer's choosing (like anything electronic), and the impulse will come out as a specter. These ghosts usually emerge from anything electrical, such as power outlets, lamps, electrified fences, or computers.

A specter in the real world is a floating, polymorphic energy field that is controlled by specified programs. They have control over their form and density, allowing the specter to be immune to harmful forces and physically interact with solid objects. In the episode Franz Hopper, it was shown that the specter itself can be used as a weapon, by entering and blocking a person's respiratory airways through the ears, nose, and mouth, efficiently suffocating them.

Possession

Possession of an object or a living being is the specter's main power. It melds with the vessel and can modify them on a molecular level. This allows the programmer of the specter to control electronics, networks, physical objects, and living beings.

Regardless of what or whomever is possessed, the specter controlling the vessel will disappear when the Tower is neutralized, and the victim will lose consciousness with no memory of events during his time being possessed. With pixelized humans, the specter also causes the person to have the eye of X.A.N.A.. in his or her eye, but the specter can change it back to normal to hide its true self as shown in "Double Trouble".

Jeremie created a specter similar to X.A.N.A.'s to pixelize Odd in "Tip-Top Shape", but gave him the ability to be mostly stand-alone.

People who regularly fight X.A.N.A. on Lyoko can become resistant to possession, as demonstrated in "Mister Pück".

In Code Lyoko Evolution, X.A.N.A. uses specters to absorb Aelita, Odd, Ulrich, and Yumi's source codes.

Polymorphic Clone

Polymorphic clones are really specters that have the ability to impersonate humans. They also have powers similar to a pixelized human, like inhuman strength and speed, and can manipulate electromagnetic energy. Their resolution can degrade when they're struck. Noteworthy human-form specters include X.A.N.A. Yumi, the William Clone, and the Jeremie Clone.

Monster specters

X.A.N.A. can also send monsters into the real world through teleportation as specters in the image of their Lyoko manifestations. This was shown in Hard Luck when X.A.N.A. materialized Kankrelats as specters into its military base holding Desert Replika.

Xanadu specters

Specters also appeared in Code Lyoko's first formal pilot, Garage Kids. In this, they appeared as black ghost-like creatures that emerged from electronics. First, they emerged from somebody's desktop computer, and again from Jeremie's laptop. Later on Xanadu, they attack both Ulrich and a tower.
