X.A.N.A. Aelita is Aelita when she's under the control of X.A.N.A..


Due to Aelita oftentimes being critical to the success of X.A.N.A.'s plans, oftentimes, the multi-agent program will attempt to control her. While X.A.N.A. is not normally capable of possessing the Lyoko Warriors sans Jeremie due to becoming immune via their constant virtualizations, the program has access to loopholes. As such, X.A.N.A. usually possesses her by using the Scyphozoa when on Lyoko. As revealed in Wrong Exposure, in addition to brainwashing her, X.A.N.A. also has the Scyphozoa plant an inhibitor inside of Aelita to prevent manual devirtualization from the terminal, in order to make her accomplish the program's goals without interference. Due to not knowing what would happen if the return to the past was used while Aelita was under X.A.N.A.'s influence (though it was likely that it carried the risk of her being under X.A.N.A.'s control for good), it was not used as a counter-measure.


In Saint Valentine's Day, Aelita was first possessed by a corrupted program chip made by X.A.N.A. and hidden inside a pearl-like necklace she received on Valentine Day's morning, in the real world. The necklace enabled X.A.N.A. to bypass the restriction of possessing the Lyoko Warriors, as it was not done via a spectre. While under X.A.N.A.'s control, Aelita mainly behaved the same, albeit she was a tad more flirtatious. Once on Lyoko, the Eye of X.A.N.A. was not seen in her eyes but instead on her forehead (similar to William in season 4). After it was made clear that X.A.N.A. was influencing her, Aelita's only impulse was to deliver herself to the Scyphozoa, so that X.A.N.A. could free itself from Lyoko. X.A.N.A. was forced to relinquish its grip once Odd started shooting at Aelita, and back in the real world, the necklace was destroyed.

While under X.A.N.A.'s control during this and other missions in Season 3, Aelita behaved much like X.A.N.A. itself, never talking or showing much emotion besides anger, and, on one occasion, smugness. In addition, any possessions via the Scyphozoa result in the Eye of X.A.N.A. appearing in Aelita's eyes.

In Lyoko Minus One, X.A.N.A. sent the Scyphozoa after Aelita once again, whereupon the monster implanted a mind control program into Aelita, allowing X.A.N.A. to force her to delete the Forest Sector after a Tarantula took her to a way tower. It was revealed that X.A.N.A., knowing that the surface sectors allowed the Lyoko Warriors to counter attacks on the Core of Lyoko, was planning to destroy all of the surface sectors so as to prevent the usage of SCIPIO, as the code was required in order to gain access to Sector Five.

X.A.N.A. was able to possess Aelita again in The Pretender, sending her off with a Manta to a way tower and a squadron of Hornets, who were able to destroy Ulrich's katana. Despite Ulrich's best efforts, he was not able to stop X.A.N.A. Aelita from deleting the Desert Sector.

X.A.N.A. Aelita appeared again during The Secret, safeguarded by a Megatank, so that she would delete the Ice Sector. However, Yumi was able to stop her, though both girls were devirtualized. It was revealed that doing so would break X.A.N.A.'s control, as Aelita did not show any signs of being under X.A.N.A.'s control afterwards. Unfortunately, this proved to be a temporary measure, as Aelita was forced to delete the Ice Sector anyways in Sabotage so that the Supercomputer would not lose all of its data due to X.A.N.A.'s earlier attack.

X.A.N.A. Aelita was utilized again in Double Trouble, where X.A.N.A sent a Polymorphic Specter which took form of Jeremie Clone to bug the Supercomputer to prevent interference from Lyoko as well as Yumi and Odd's avatars so they couldn't stop Scyphozoa from possessing Aelita. The tactic proved successful, as X.A.N.A. Aelita was able to delete the Mountain Sector without much trouble, despite Yumi's efforts when her avatar was debuged by real Jeremie.

X.A.N.A. Aelita appeared one final time in Wrong Exposure, where the Scyphozoa brainwashed Aelita so she would jump into the Digital Sea to fulfill X.A.N.A.'s objective to lure out Franz Hopper. Ulrich attempted to devirtualize her, but X.A.N.A. Aelita proved to be extremely difficult to handle, stealing one of Ulrich's katanas and engaging him in a sword battle. During this time, X.A.N.A. Aelita acted in a fairly deranged manner, walking towards the Digital Sea in a slow stupor one moment, before lashing at her opponents in swift motion, all while sneering, screaming, and smirking when attacking Ulrich, not unlike X.A.N.A. William. Jeremie was able to use a new program to reboot the Supercomputer, breaking Aelita out of X.A.N.A.'s control before she could devirtualize Ulrich, though it exhausted her greatly and she lost almost all of her life points.

X.A.N.A. Aelita has not been seen since.

  • Aelita is one of two people who were possessed by the Scyphozoa.
  • Despite being possessed the most by the Scyphozoa, it has occurred for the shortest of all Scyphozoa possessions; the only other one being William, who had the longest X.A.N.A.-fication in history.
  • In Wrong Exposure, X.A.N.A. Aelita steals one of Ulrich's katanas using the same move the latter did in Revelation to steal back his katana from his polymorphic clone, which demostrates that X.A.N.A learns from his defeats.
