Code Lyoko: Evolution

Jeremy Belpois (French: Jérémy Belpois)

Portrayed by: Marin Lafitte

A computer genius and top student in class, Jeremy was the one who originally found the Supercomputer in the nearby abandoned factory and turned it on, beginning the group's struggle against X.A.N.A.. He believed he'd defeated X.A.N.A. using a multi-agent system of his own creation in the finale of Code Lyoko and was dubious that X.A.N.A. had returned at the start of Code Lyoko: Evolution. Once the Lyoko Warriors start fighting X.A.N.A. again, Jeremy returns to his workaholic nature, often staying up late to work on programs such as the virus he intends to use to destroy the Cortex. He spends a lot of time working alongside Laura, causing Aelita to become jealous. He is able to outsmart both X.A.N.A. and Professor Tyron most of the time.

Aelita Schaeffer

Portrayed by: Léonie Berthonnaud

Primarily known by her alias, Aelita Stones, she's the smartest of the group alongside Jeremy. Her father, Franz Hopper, created the Supercomputer, Lyoko and X.A.N.A., and ultimately sacrificed himself to try and stop X.A.N.A. once and for all. Aelita sometimes struggles with the reality of his death and the return of the enemy he died trying to defeat. She has a strong bond with Jeremy but his relationship with Laura causes her to be jealous. After she finds out that her mother, Anthea, is alive and working with Professor Tyron, Aelita is determined to contact her so that they can reunite. Aelita has been implanted with some of X.A.N.A.'s source codes, making her a primary target for its polymorphic specters.

On Lyoko, Aelita has pointed elf ears and the ability to summon a pair of pink angel wings in order to fly. Her weapon is her "energy fields," pink orbs of pure plasma that can be thrown to destroy an enemy from a distance. She can also generate a large energy shield made of the same sort of pink plasma. She is able to still deactivate towers on Lyoko, due to the annex program she has had for several years. Due to the similarities between Tyron's supercomputer and her father's, Aelita is able to open the door of the Core Room in the Cortex with her creativity, a blue aura around her body as opposed to her melodic, siren-like vocals. Her additional ability of second sight is not used.

Odd Della Robia

Portrayed by: Gulliver Bevernaege

The comic relief of the group and a bad student who isn't interested in studying. He shares a dorm with Ulrich, where he used to keep his dog Kiwi. Between the events of Code Lyoko and Code Lyoko: Evolution, Odd sent Kiwi home to stay with his sisters, but he misses his dog dearly. He's considered a ladies man and spends most of the series pursuing his love interest Samantha Suarez. His hair is now brown instead of blond, but retains the purple spot at the front. Odd has been implanted with some of X.A.N.A.'s source codes and is a target for X.A.N.A.'s specters.

On the virtual worlds of Lyoko and the Cortex, Odd is like a cat, having a tail and clawed gloves which he can use to climb walls. He can summon an additional set of gauntlets over his gloves that shoot many blue "laser arrows" all at once, wiping out several monsters or ninjas from a distance. While he still retains some of X.A.N.A.'s source codes, he is fully capable of deactivating towers on Lyoko, an ability he loses in "Massacre." As with the original show, his only ability "future flash" is never given back to him nor his one-time ability of teleportation, even though he tries to get Jeremie to give them more and stronger superpowers, such as laser eyes.

Ulrich Stern

Portrayed by: Quentin Merabet

A more reserved member of the group, Ulrich has a hard time sharing his feelings. His parents pressure him to achieve well in school, but he has difficulty learning and living up to their expectations. In his off-time he practices karate and judo with Yumi, whom he has a crush on. He often butts heads with William, who he sees as a rival. Ulrich has been implanted with some of X.A.N.A.'s source codes and is a target for its spectres.

On Lyoko, Ulrich wields dual katanas. His "super sprint" ability allows him to dash at high speeds and to run on walls, and his "Triplicate" power lets him create two temporary clones of himself. While he still retains some of X.A.N.A.'s source codes, he's capable of deactivating towers on Lyoko until "Massacre."

Yumi Ishiyama

Portrayed by: Mélanie Tran

A fairly reserved student who lives near and attends Kadic. She is the oldest of the group. She is of Japanese descent. She was initially very resistant to the idea of turning the Supercomputer back on again after signs of X.A.N.A.'s return. She practices judo with Ulrich, whom she has a crush on, though it's not as obvious as Ulrich's crush on her. She's good friends with William, who's in her class, and doesn't like the idea of excluding him from the group now that X.A.N.A. has returned. Along with the rest of the Lyoko Warriors, she was implanted with some of X.A.N.A.'s source codes.

On Lyoko, Yumi's main weapons are a pair of Tessen fans which appear in her hands at will. Later on, Jeremy programs her a bō staff as well which she uses occasionally. Her superhuman balancing skills enable her to scale platforms quite easily without falling. She can deactivate towers on Lyoko as long as she still retains a few of X.A.N.A.'s source codes by the cliffhanger "finale". Her only power of her enhanced telekinesis is never used even once.

William Dunbar

Portrayed by: Diego Mestanza

An overconfident student in Yumi's class. William is initially kept uninformed about X.A.N.A.'s return because the group are distrustful of him. However, he eventually regains their trust and is allowed to fight alongside them. He still has feelings for Yumi but is more respectful of her boundaries. He has a rivalry with Ulrich. As he wasn't present on Lyoko during the final battle of the original series, he wasn't implanted with any of X.A.N.A.'s source codes.

On Lyoko, he retains his black outfit and some of his powers from his time under X.A.N.A.'s control: enhanced strength and "Supersmoke," which allows him to transform into a cloud of black smoke, move at great speed and even fly. His weapon is a giant sword which can release disc-shaped shock waves that can wipe out two monsters and Ninjas from a distance. He has not used his levitation ability.

Laura Gauthier

Portrayed by: Pauline Serieys

The temporary seventh member of the Lyoko Warriors. She's a highly intelligent student, rivaling Jeremy in class, and has a keen interest in computing. She discovers Lyoko, the factory, and the Supercomputer after following William to the factory without his noticing. Her main role is to assist Jeremy in matters that even Aelita could not help in, such as advanced coding and constructing viruses. She is generally viewed with suspicion by the others due to her uninitiated status. She lacks sympathy towards Aelita's situation and enjoys spending time with Jeremy, so Aelita displays some animosity towards her. When Laura rebels against Jeremy, goes to the factory with William and sends him to the Cortex, William nearly gets captured by X.A.N.A. as he did in the original series. After the Lyoko Warriors stop the Scyphozoa from fully possessing William, Jeremy kicks Laura out of the group and erases her memories of the factory, the supercomputer and Lyoko. However, due to having a certain card in her bag, she inadvertently and unknowingly gives Tyron direct information on the whereabouts of his adversaries.

X.A.N.A.

Sometimes spelled XANA. A very powerful and dangerous multi-agent system or artificial intelligence that returns from Code Lyoko to serve as the main antagonist of the new series. After its supposed destruction in the original series, it was revealed in Code Lyoko: Evolution that X.A.N.A. survived by taking refuge in the Cortex, a sector generated by Professor Tyron's supercomputer. X.A.N.A. activates towers on Lyoko and sends specters in the form of human beings to get close to the heroes and drain them of its source codes, which are a share of its power implanted in them before its previous downfall. X.A.N.A. is determined to become complete again so it can take full control of the world network.

X.A.N.A.'s Monsters

The virtual creatures X.A.N.A. uses to protect the towers it has activated and try to stop the heroes from accessing them, or to stop them from reaching the center of the Cortex. There are several different types of monsters, some inspired by real-life animals. X.A.N.A. also sometimes sends monsters to keep Tyron's Ninja avatars from finding out about X.A.N.A.'s presence in his supercomputer.

Professor Lowell Tyron

Portrayed by: Franck Beckmann

The secondary antagonist, responsible for the creation of the Cortex within his own quantum supercomputer in Switzerland. His character is unintentionally responsible for X.A.N.A.'s rebirth as well as antagonizing Jeremy and his friends. 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; this also makes him Aelita's stepfather.

Ninjas

Human avatars, similar to the five Lyoko Warriors, that are sent to the Cortex by Professor Tyron when necessary from his laboratory somewhere in Switzerland. Tyron lacks the technology to virtualize human beings directly into a virtual world, so he equips his staff with special suits that allow them to control Ninja avatars on the Cortex. Each Ninja is identical: faceless and green with white stripes, and armed with dual swords. They're masters of martial arts and stealth, with the ability to melt into the floor and resurface behind an enemy to take them by surprise. They're also able to travel across the Digital Sea without any protection. Their mission is to stop the Lyoko Warriors from interfering with the Cortex, and they make formidable opponents. Their identities are never revealed.

Jim Morales (French: Jim Moralès)

Portrayed by: Bastien Thelliez

The physical education teacher at Kadic Academy and the chief disciplinarian. He often makes long speeches about the sports he teaches, or begins to reminisce about stories of his past before being interrupted by someone or cutting himself off. He can be quite serious when rules are broken, but he's also kind towards students in need. The heroes often cross him but his memory is usually erased by a Return to the Past.

Samantha Suarez

Portrayed by: Louise Vallat

Odd's love interest. She seems to have known Odd for a long time, but Samantha only started boarding at Kadic Academy 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, most likely due to the fact that Odd can't tell her the truth about why he keeps running off.

Anthea Schaeffer

Portrayed by: Sandrine Rigaux

The long-lost mother of Aelita and widow of the late Waldo Franz Shaffer. In the original series, Anthea was kidnapped by men in black suits when Aelita was very young and her fate was never known. In Code Lyoko: Evolution, however, she is revealed be very much alive and working alongside Professor Tyron, and under the impression that her daughter was dead. She and Tyron married five years prior to the events of the sequel. After Aelita manages to contact her mother and tell her that she's alive, Anthea sends her back a message expressing her happiness and her wish that Aelita come to Switzerland to live with her and her husband. Unfortunately, the sequel concluded before more episodes of the group's mission to find her and reunite her with Aelita were made.

Elisabeth "Sissi" Delmas

Portrayed by: Clémency Haynes

The principal's daughter and a student at Kadic Academy. Unlike in the original series, she no longer seems interested in Ulrich, and she tries to make friends with Aelita and Yumi.

Jean-Pierre Delmas

Portrayed by: Eric Soubelet.

The principal of Kadic Academy and Sissi's father. His is very gullible which makes it better for the quintet to keep their secret as heroes from everyone.

Suzanne Hertz

Portrayed by: Sophie Fougère

A science teacher at Kadic who replaced Franz Hopper, as she was once his assistant.

Waldo Franz Schaeffer

Portrayed by: Hugues Massinat.

Primarily known by his alias, Franz Hopper, he is the late father of Aelita and first husband of Anthea Hopper-Tyron. He had died sacrificing himself to assist Jeremy in wiping out X.A.N.A. once and for all, at least for a time, in the penultimate episode of the original series and only appears in old videos or photographs. His very essence seems to be linked with the Heart of Lyoko itself, as Aelita is known to be speaking to something or someone when wanting to consult him about whether he had anything to do with X.A.N.A.'s sudden return, and later assures him that she will find his wife.
