List of ''Code Lyoko'' characters

Jeremie Belpois

Jeremie Belpois (French: Raphaëlle Bruneau, English: Sharon Mann), is an 11-year-old boy whose nicknamed Einstein and sometimes spelled Jeremy, is a top-of-the-class student who finds and starts the factory's supercomputer while looking for parts to build a robot. As part of the group, he specializes in programming new ways to defeat XANA and monitors the group while they are on Lyoko. Because he is not very athletic and is more computer savvy; Jeremie almost never goes to Lyoko, doing it a couple of times and vowing to never do it again after that. Jeremie also has a crush on Aelita since he first turned on the supercomputer, therefore revitalizing not only the virtual world Lyoko, but the malevolent multi-agent system X.A.N.A. as well. He seems to be the main archenemy of X.A.N.A. as it appears to want to get rid of him more than the others.

Aelita Schaeffer

Aelita Schaeffer (French: Sophie Landresse, English: Sharon Mann), better known as Aelita Stones, is the daughter of Franz (creator of Lyoko) and Anthea Hopper. Nicknamed "Miss Einstein" and "Princess," she is the smartest of the group, along with Jeremy. As a little girl, she lost her mother. When a group of suited men came to her home, the "Hermitage," she and her father fled and virtualized themselves on Lyoko. Between the virtualization and Jeremy's discovery of the supercomputer, XANA stole an important memory fragment that inhibited her from becoming fully human again. After this fragment is retrieved, she is no longer linked to the supercomputer. In Lyoko, she has an elf-like appearance, similar to that of "Mr. Puck," a toy elf from her childhood. After becoming human, she often has premonitions and nightmares of what is to come or what was. From Seasons 1 to 2, Aelita has no way of attacking. In Season 3, she gains the ability to use "energy fields”, pink spheres which seem to be made out of plasma. In Season 1 only, Aelita had a "sixth sense" (sometimes called "second sight") ability that allowed her to see when towers were activated. Throughout the series, Aelita uses her "creativity" power to do various things such as create platforms over the void and create holes in the ground. Starting from Season 4, Jeremie gave Aelita a flight ability, which appears as a pair of light pink angel wings. In the video games, Aelita can use levitation to fly over platforms for a brief period of time, and use petrification to encase enemies in ice blocks. She is enrolled as a border student at Kadic after full materialization. To eliminate problems, she is given the fake surname Stones and pretends to be Odd’s cousin.

Odd Della Robbia

Odd Della Robbia (French: Raphaëlle Bruneau, English: Matthew Géczy) is the comic relief of the group. Odd is credited as having great potential when it comes to school, but rarely uses it, and gets bad grades due to his lack of studying. He shares a dorm with Ulrich and has a dog named Kiwi, which he hides in a dresser because pets aren't allowed at Kadic. However, in the 5th season, Odd left him home with one of his sisters. He attempts to go out with girls, but his bad habits get in the way. Before he attend Kadic he lived with his parents and his five sisters. Odd's hair has a purple spot and is upright, except for the first episode. He generally wears a purple hoodie and he is clothed like a cat when in Lyoko. He shoots "laser arrows" to attack his enemies. In Season 1 only, he had a "Future Flash" ability, which allowed him to foresee certain future events, but was deleted when Jeremy rebooted the Supercomputer. Starting in Season 2, Odd sometimes uses a shield. Near the end of Season 3, Jeremie attempted to program Odd a teleportation ability, but failed. Another one of Odd’s abilities is being able to climb on walls. In the video games, Odd uses an ability labeled "Feline Jump" to replace his regular climbing. He also has the ability to use time control in Code Lyoko: Quest for Infinity.

Ulrich Stern

Ulrich Stern (French: Marie-Line Landerwijn, English: Barbara Weber-Scaff) is one of the more laid back students who is expected to show potential in front of his parents (but mostly towards his father). In his off-time he practices Pencak silat with Yumi, who "is a friend and that's all." Before Lyoko, he was annoyed with Sissi, so he often has to deal with or use her as the warriors deal with XANA and their own personal issues within the group, sometimes he suffers with Vertigo which makes it hard to participate in rock climbing. While in Lyoko, he is clothed in a yellow and black suit. Ulrich's main weapon is a katana, which becomes two katanas in Season 4. He uses abilities such as Triplicate to create 2 clones of himself, and a related technique labeled "Triangulate," which is a type of Triplicate that allows Ulrich to ambush enemies with his clones. Starting Season 2, Ulrich uses "super sprint" to dash at high speed. In the video games, Ulrich uses his "super reflexes" to break through walls. He is the second-least knowledgeable about using the supercomputer.

Yumi Ishiyama

Yumi Ishiyama (French: Géraldine Frippiat, English: Mirabelle Kirkland) is a fairly reserved student who lives near and attends Kadic. She is the oldest of the group. She is of Japanese descent, and has one younger brother, Hiroki. Because of her parents and culture, she must maintain good grades and observe family values. At home, she generally has to deal with marital issues between her parents. She is an old friend of William Dunbar, who transferred to Kadic during Season 2. She practices pencak silat with Ulrich, but because of all the tensions created by Lyoko, she and Ulrich "are just friends and that's it." She always wears black, and on Lyoko she is clothed with a geisha-inspired outfit with a big bowtie. Yumi's main weapon is a tessen fan, which increases to two in Season 2. In Code Lyoko: Evolution, Jeremie occasionally programs Yumi a bo. Yumi's only power in the show is telekinesis, but in the video games, she has enhanced balancing skills (plainly called Balance). She has also the most knowledgeable about using the quantum supercomputer besides Jeremy, until Aelita becomes completely human.

William Dunbar

William Dunbar (French: Mathieu Moreau, English: David Gasman) is an overconfident student at Kadic Academy who often fights Ulrich for Yumi's attention. When he was first introduced in the series he was shown to be a loner (due to him kept getting expelled from other schools), however Yumi soon sees him as a friend and he soon develops feelings for her. Despite his rifts with the other Lyoko Warriors, he becomes the closest thing to a trusted ally they have. Although Jeremy, Ulrich, Odd, and Aelita initially voted in favor of his joining them, they are unable to reach consensus due to Yumi's disapproval. Eventually, however, the vote becomes unanimous when William's membership is necessary. On his first mission in Lyoko, he is captured and possessed by XANA, who ensnares William as its puppet. From that point on, a clone of William, created by Jeremy, is used to pose as the real William until Jeremy is able to free him. Unfortunately, Jeremy's program is extremely malfunction-prone, causing the William clone to act either abysmally unintelligent or unpredictable and dangerous. Near the end of the series the clone starts developing several human-like traits, which he eventually uses to help the warriors. In Lyoko, William carries a giant Zweihänder sword, which can release shock waves, and has a white outfit, which becomes black when he is under XANA's control with a spike gauntlet wrist. In Code Lyoko: Evolution, it is revealed that he has somehow kept his "supersmoke" ability from his time with XANA, which allows him to travel at high speed in the form of a black smoke. He travels to the factory on foot and is unknowledgeable on how to use the supercomputer.

X.A.N.A.

X.A.N.A. (also called XANA) is a supernaturally powerful computer program that serves as the main antagonist of the series. It was originally created and programmed by Franz Hopper in the 1990s, designed to destroy Project Carthage - a military software system that Franz Hopper had previously been closely involved with. He mentions that his motives were to prevent the French government from obtaining access to Project Carthage. Unfortunately, due to his repeated returns to the past, XANA grew stronger and smarter until it eventually became sentient; choosing to rebel against Franz. It then trapped Franz and his daughter Aelita inside Lyoko. Luckily, Franz was able to shut down the supercomputer to trap XANA and prevent it from wreaking havoc on the real world.

XANA displays no mercy towards those who stand in its way, waging attacks through Lyoko structures known as "towers" into the real world, often attempting mortal harm against the main characters. Being a computer program, XANA has no actual physical form. Instead, XANA acts through virtual monsters and programs it creates in Lyoko and while possessing networks, objects, and eventually humans in the physical world. Objects controlled by XANA are marked with a symbol called the Eye of XANA constantly symbolizing its presence among them. It usually programs monsters inside Lyoko in order to prevent the heroes from deactivating the Towers and ruining his plans. It uses the towers to access the electrical networks on Earth. It has the ability to conjure energy apparitions from outlets called spectres, which allow it to take possession of any computer system, physical objects, and/or living things. Whenever a human is possessed by XANA, that person does its bidding and becomes pixelized, given powers that appear supernatural, such as increased strength, speed, and endurance, manipulation of electricity, influence over objects and devices, and other powers. Possessed humans pupils turn into the Eye of XANA symbol.

After its supposed destruction in the penultimate episode of the original series, it was revealed in Code Lyoko: Evolution that XANA survived by taking refuge in the Cortex, a sector generated by Professor Tyron's supercomputer. With the assistance of Spectres, they will drain the four heroes for source codes which is half of its power inplated before the previous downfall, urging to reach a Hundred which it will use to take full control of the world network.

The only known physical incarnation of XANA appeared in the Season 1, episode titled "Ghost Channel;" where after having its disguise as Jeremy being exposed, he transformed into a demonic caricature figure of Jeremy and it and tried to kill all of the Warriors. XANA's voice was provided by David Gasman in this episode.

Franz Hopper

Waldo Franz Schaeffer (French: Mathieu Moreau, English: Paul Bandey), better known as Franz Hopper (after he legally changed their family's last name to his wife's maiden name), is the creator of both Lyoko and XANA, and was involved in the creation of Project Carthage. Formerly a science teacher at Kadic Academy, he vanished suddenly while living in a house in the school park called the Hermitage. In a nearby abandoned factory, he constructed the supercomputer on which he created Lyoko, only to be intercepted by XANA during his and Aelita's virtualization. Franz was forced to shut the supercomputer down, until it was discovered by the boy genius, Jeremy Belpois, nearly ten years later. In the penultimate episode of the cartoon, he dies in Lyoko, allowing Jeremie to bring XANA down once and for all.

Anthea Hopper

Anthea Hopper was the wife of the computer scientist Waldo Franz Schaeffer, and Aelita's long-lost mother. In the original series, she is depicted as a young woman with fair skin, black eyes, and bright pink waist-length hair (yellow in the 5th season), which Aelita had inherited. Prior to the series, she had been captured by men in black suits and had not been seen or heard from for several years. In Code Lyoko: Evolution, she is revealed be very much alive and working alongside Professor Tyron, who had convinced her that her daughter was dead. Aelita, however, succeeded in contacting her at last and informing Anthea that she was her daughter; alive and well. With the mention of Lyoko, Anthea realized that it was indeed Aelita, but the connection was severed by Tyron before she could react further. In the cliffhanger episode, Ultimate Mission, she had sent a video message, saying how happy she was to know that Aelita was alive.

Laura Gauthier

Laura Gauthier is a supporting character who appears in Code Lyoko: Evolution as the temporary seventh member of the Lyoko Warriors. She discovered Lyoko, the factory, and the supercomputer after following William to the factory, in which he didn't know he was being followed. Her main role was to assist Jeremie in matters that even Aelita could not help in, such as advanced coding and constructing viruses. When she rebels against Jeremie and goes to the factory with William and sends him to the Cortex, William nearly gets captured by XANA as he did in the original series. After the Lyoko Warriors stop the Scyphozoa from fully possessing William, Jeremie kicks Laura out of the group. It has revealed that she has a brother named Theo who attended Kadic before her.

Professor Tyron

Professor Tyron is the secondary antagonist in Code Lyoko: Evolution. He is responsible for the creation of the Cortex via his own quantum supercomputer in Switzerland. He used to work with Franz Hopper, but was fired after not listening to his instructions and being too conceited. He later betrayed him by stealing blueprints to create his own supercomputer. After an unknown sequence of events, he married Anthea to get his hands on Franz Hopper's personal files (possibly to recreate project carthage); this also makes him Aelita's stepfather.

Samantha Suarez

Samantha Suarez is the Code Lyoko: Evolution adaptation of Samantha Knight from the original series. She seems to have known Odd for a long time, but Samantha only started boarding at Kadic Academy very recently after a dispute with her father. Odd begins to pursue her as a love interest, even buying her a thousand red roses when he believes he's won the lottery. Samantha is hesitant about starting a relationship with him again, most likely due to the fact that Odd can't tell her the truth about why he keeps running off. Unlike the Sam from the first series this one has a sun hat and has light skin.
