List of Code Lyoko characters

This is a list of characters in the French animated television series Code Lyoko. It covers the protagonists, the antagonist, and supporting characters.

Main Characters

The main characters are Aelita Stones, Jeremie Belpois, Odd Della Robbia, Ulrich Stern, Yumi Ishiyama, William Dunbar (later on), and XANA. The first five are the protagonists, commonly referred to as "the group" or "Lyoko warriors" in the series. They are the ones who attempt to foil XANA's plans. The sixth name mention can be considered either a protagonist or an antagonist. The primary antagonist is XANA, who seeks to take over the world.

Aelita

Aelita Stones (eye-lee-tə) (voiced by Sharon Mann) is the nearly youngest girl in the group and the most naive of the five, having had comparatively less experience with the real world than her friends. She is thought to be an A.I. within Lyoko for the first two seasons. She is the daughter of Franz and Anthea Hopper, who designed both the supercomputer and XANA. She manages to settle into her new life by the start of the third season, making more jokes and generally displaying less naivety, and more reflected in her combat skills. Aelita is also capable of running the supercomputer in the event that Jeremie cannot. In the show it displays that she has feelings for Jeremie. On Earth, her full name is Aelita Stones. In "Wrong Exposure" it is revealed that Aelita's true last name is Schaeffer, but that her father had changed it to Hopper, her mother's maiden name, to make a fresh start. Aelita's mother, Anthea, disappeared when she was young. In "Distant Memory," it was mentioned that Anthea was kidnapped by the Men in Black when Aelita was a little girl and was never seen again. For the first and second seasons, Aelita is 12 years old and in 8th grade, having been skipped ahead; for the third season she is 13 and in 9th grade, and in the fourth season, she is 14 (and still in 9th grade).

Aelita's hair is pink and often thought to be dyed, but is in fact natural. She wears three main outfits throughout the series. Her daytime outfit in the first season is a maroon skirt, yellow shirt and pink jacket. She wears a dark pink jumper dress over a light pink hooded long sleeved shirt and dark pink knee boots as a trademark outfit for the both seasons. But the non-trademark outfit, her outfit consists of a dark purple dress that comes to her knees and light pink Quarter length leggings underneath. Her boots are a deep red. Her night clothes consist of white socks (sometimes barefoot) and an over sized pink t-shirt with a red letter "A" on the front.

For the first three seasons, Aelita's Lyoko attire consists of a pink mini skirt and a matching top that go over trousers and a long shirt that are both off-white, and matching shoes. She also has elf-like ears, with a small dangle earring in the left one. Her eyes are green. In the fourth season, Aelita receives a new pink form-fitting suit on Lyoko, which has a pair of retractable energy wings that enable Aelita to fly. Also in the fourth season, Jeremie creates a program to send the Warriors to earth to destroy the Replika's as Spectre forms. Aelita's Spectre Form is a match to her original, except that it seems she either can't use her wings or doesn't need to.

Her main interest is music, specifically audio mixing. Her childhood memories show that Franz Hopper taught her to play the piano at an early age. In the fourth season, she wins a contest to star in one of the Subdigitals' concerts. She, like Jeremie, is also a capable programmer and an excellent student. Aelita has four appearances on Lyoko. In season 1, she was a Lyoko being and wasn't allowed to be devirtualized and doesn't have any powers except for her "creativity." In season 2, Aelita is a human being, but doesn't have any weapons. In seasons 3 and 4, Aelita can conjure pink orbs from her hands called "Energy Fields."

Aelita's main power on Lyoko is her "creativity," which allows her to alter small portions of Lyoko's terrain at will. She can use the same power to create clones of herself, though they have limited functionality, acting in a pre-determined manner. As mentioned earlier, Aelita also possesses the power to deactivate the towers on Lyoko, the main component in stopping XANA's attacks in the real world. In the third season, Aelita is able to defend herself by generating pink orbs called "Energy Fields," which can destroy any monster on contact, regardless of where they hit, excluding Megatanks. Two energy fields can also be touched together to form a makeshift shield. Additionally, Aelita can charge her "Energy Fields" into a much larger ball of energy, which can do more damage than a normal Energy Field attack. Over time she also developes pink wings, which she uses for transportation; she can use them at her own will. For the first two seasons, she could not be devirtualized normally as the others could, requiring a special program to bring her to Earth, but after that is able to leave in the same manner as the others.

Jeremy Belpois

Jeremy Belpois (voiced by Sharon Mann, also called Jérémie in France) is the brains of the group and the youngest, directing their missions from the supercomputer and designing various programs to improve their chances of victory (though, as a recurring plot device, these programs almost always malfunction). Jeremie does not participate in the battles on Lyoko because he is needed back in the real world for technical support and to run the virtualization, devirtualization, and other computer programs in case of an emergency. He has attempted to visit Lyoko two times, the first time in the episode "Frontier" in order to make amends with Aelita, and again in the episode "Mr. Pück" to increase his resistance to XANA. He vowed never to return after the third time, due in part to his reportedly ridiculous-looking outfit and a poor experience with XANA's minions. For the 1st and 2nd season he is 13-years-old and in 8th grade. In the 3rd season he is 14, and in the 4th he is 15 (and still in 9th grade.)

Jeremie has blonde hair. On Earth in the first three seasons, he wears a blue turtleneck, brown pants and blue-gray shoes. He also has glasses, because he is nearsighted. In Season 4, his outfit is a dark red long-sleeve shirt, brown pants with light blue stripes going down the side of the legs, and dark blue shoes. His pajamas are dark blue.

Something of a workaholic, Jeremie invests the majority of his time into finding ways of stopping XANA, having spent the entirety of season one trying to materialize Aelita onto the real world, and spent all of season two trying to make an anti-virus after XANA infected her. In season three, he spends most of his time trying to find a way to virtualize the group into the Internet directly, until XANA possessed the newly inducted William and destroyed Lyoko. At the end of the season, Jeremie receives a message from Franz Hopper, and manages to recreate Lyoko using the code sent to him. In season 4, he spends the majority of his time locating Replikas, deciphering data from the Internet, and trying to free William from XANA. From Season 2 onwards, one of his major overall goals is to free Aelita's father, Franz.

He has a multiterminal computer of his own in his room, by which he develops programs, tests them prior to use within the factory's supercomputer, and, during the first season, communicates with Aelita within the supercomputer. He uses a screen saver that closely resembles the "falling green letters" theme used in The Matrix series of movies, supposedly a homage. He has a black and white poster of Einstein.

Often, his determination to fight against XANA will take priority and he will leave his friends in the interests of working more. They rarely respond positively to this; however, he usually finds a way to make things up by the end of the episode.

Jeremie was the one who discovered Lyoko, as well as Aelita, and over the first season he became very attracted to her. He is very attracted to Aelita's intellect, curiosity, and bravery, and although Jeremie can be shy at times, he has sought a romantic relationship with her, and it has been seen that Aelita feels the same way in many episodes.

Jeremie has visited Lyoko a total of three times. In the episode "Frontier", Jeremie gets in an argument with Aelita, and later tries to go to Lyoko to apologize. He was, however, trapped in between Lyoko and the real world due to an error in the scanning process. In the episode "Ghost Channel," XANA had created a sort of fake earth within Lyoko, trapping Odd, Ulrich, and Yumi. Jeremie went to this fake projection of earth and stopped XANA with Aelita's help, but he was devirtualized immediately afterwards and never actually went to Lyoko itself. At the end of another episode, "Mister Puck", Jeremie, Ulrich, and Odd came from Lyoko, where Ulrich jokes about how fast he was defeated by a Megatank. After that he said he would never go into Lyoko again. Jeremie's Lyoko form is never seen in the series, and Odd describes it, tactfully, as "ridiculous."

Odd Della Robbia

Odd Della Robbia (voiced by Matthew Géczy) is the prankster of the group, acting less serious and more carefree than the others in any given situation. His attitude extends to most forms of danger, which Odd only seems to take seriously when responsible for the welfare of others. While Odd doesn't appear to be a serious student, he maintains a 75% average at one point, apparently aided by high art scores as well as his propensity to copy the papers of others during those tests he actually attempts to pass. During his free time, he prefers to work on guitar, film, drawing, other forms of art, as well as skateboarding, and trying to find his one true love. For the 1st and 2nd season he is 13-years-old and in 8th grade. In the 3rd and 4th he is in 9th grade and is 14 in season 3 and 15 in season 4.

Odd has long hair spiked to a peak, with a splotch of purple in the center (except for in the prequel episode, XANA Awakens, in which he wore his hair down until after the first time he had been to Lyoko, calling it 'Lyoko style.'). The first of Odd's two outfits in the series consists of a long-sleeve shirt and bellbottom pants, and platform shoes. His hair is styled into a large point in the same fashion as his hair on Lyoko. He also has a purple diamond on the front of his hair (which is naturally that color, as seen in both "Unchartered Territory" and "Revelation"). In the fourth season, his outfit consists of a purple hooded sweatshirt with a pink shirt underneath, purple bellbottoms, and dark red-orange shoes. His night clothes are red and yellow, not purple, and probably due to the fact he did not buy them (orange boxers/boxer briefs and a red shirt). In the fourth season, Odd is able to be sent by Jeremie to a Replika computer to destroy it as a Spectre. While in this Spectre form, Odd closely resembles his fourth season Lyoko suit, except that he has three toe claws and his gloves end at elbow length instead of mid upper arm.

Odd considers himself to be something of a ladies' man, having managed to date almost every (similarly aged) girl at the school in the two years he's been attending it, sometimes two at a time. A recurring theme in the series is Odd attempting to impress one girl or another, if he is not already dating them. He has shown a close attachment to a girl named Sam that doesn't attend his school, but these feelings might have changed as she withheld information from Ulrich about a XANA attack.

Another recurring theme, though less prevalent, are jokes about Odd's size in comparison to his eating habits. Despite eating two or three portions at every meal, Odd never gains weight or height, being the shortest member of the group, which is somewhat disguised by his platform shoes and hairstyle. The school nurse attributes this to Odd's high metabolism. His feet also smell.

Odd has a pet dog named Kiwi, which he keeps in his room regardless of the school's policy. Despite the rule against dogs, most of the students know about it. Odd also shares a room with Ulrich. The others have their own rooms or live at home. This occasionally results in arguments between the two on roommate-related issues. In "Distant Memory", it is revealed that Odd has five sisters.

On Lyoko, he is dressed as a self-described "giant purple cat." The outfit is almost identical to the one he wears in the real world color-wise, but has no sleeves and is generally closer-fitting. To complete the "giant cat" motif, Odd only has four fingers (three digits and a thumb), complete with claws, and a tail. His forehead and cheeks also have purple markings on them. In the fourth season, he receives a new outfit almost identical to the previous one, except being a slimmer full-body suit, with slightly altered highlights, and with cat ears in addition to his human ones. His vehicle is the Overboard, a similarly themed, two-tone, purple and pink hoverboard. His cat themed suit creates a bit of irony, seeing as he is presumed to be more of a dog person. On the front of his Lyoko suits (both of them) there is a picture of Kiwi peeing.

Odd's gloves are equipped with laser arrow launchers, which are his main weapon. Odd prefers to attack from long-range, using his accuracy to destroy monsters out of harm's way, but will often fight close-quarters in order to get a shot in. In the first season, he can only fire 10 arrows in one setting, but eventually gains the ability to fire as many as 10,000 with a reloading program created by Jeremie. Odd's powers vary between seasons. In the first season, Odd has future flash, the ability to see into the future though not at will and only for short periods. The ability (as explained in the third season episode "Triple Trouble") was lost in the second season when Jeremie improved their abilities and described it "useless" despite the fact that it had saved them many times. In exchange, Odd gets an arm-mounted energy shield which appears when he summons it. His claws also allow him to climb up objects with ease. In the third season episode "Triple Trouble", Odd temporarily gained the power to teleport, but the program bugged up, causing him to duplicate himself both where he was when he teleported and where he teleported to. This led to particle disintegration after an extended period of time, thus forcing Jeremie to remove the power. Odd also gives a name to almost every new Monster XANA creates.

Yumi Ishiyama

Yumi Ishiyama (voiced by Mirabelle Kirkland) is the oldest member of the group and Hiroki's older sister, being one year older than the others and is of Japanese descent. Branching from this, she owns a suit of samurai armor handed down the generations she treasures very much, as well as being seen with a Totoro plushie in her room. Although sometimes a bit short-tempered, Yumi is very clever and cares greatly about her friends. Yumi varies between reasonable and stubborn at various points; though willing to reveal the supercomputer to the police in order to prevent a nuclear explosion, it takes the destruction of most of Lyoko to convince her to let William Dunbar join the group. For the 1st and 2nd season she is 14-years-old and in 9th grade. In the third season she is 15 years old and is in 10th grade. In the 4th season she is still 15 but turns 16.

Yumi's hair is half-long black, headed back and sides. In the first three seasons, she wears a black turtleneck, darker black jeans, and gray-black sneaker boots. Her hair is usually left hanging down. In the fourth season, her outfit is slightly lighter but still mainly black, consisting of a long-sleeved shirt with an extra large neck hole. Her pants cut off halfway between her ankles and knees. Her shoes are pinkish reddish sneakers.

In terms of character development, the two major themes revolving around Yumi are her relationship with Ulrich Stern and her parents' unstable marriage, the former of which is the central focus. Yumi's relationship with Ulrich remains platonic, though they almost kiss in "Routine" and decide to keep it a secret from everyone else. After discovering her real romantic feelings for Ulrich,Yumi decides to outwardly declare their relationship to be just friendship. At the start of the third season to hide her real feelings for him, though the episode "Cold Sweat" and the series finale "Echoes" implies the two eventually explore their romantic relationship again.

The second season introduces Yumi's younger brother, Hiroki. He constantly teases Yumi about being in love with Ulrich. Most of the time, Yumi acts as if she can't stand Hiroki, but episodes such as "Lost at Sea" show that Yumi does care for him.

Yumi's outfit is modeled after those worn by geisha. Her outfit consists of a short-sleeved/hemmed kimono over red tights, black thigh-length boots, red eye liner, red blush on her cheeks, a white-painted face and neck, and some red on her lips to complete the look. She also has a yellow sash tied to her back. Her hair is bunched up into a small bun with three bangs left hanging. In the fourth season, Yumi gets a new, ninja-like outfit. It consists of form-fitting, pink and purple body suit with flowered shoulder pads, but retains the yellow sash from the previous one. Her hair is worn down instead of in a bun. The geisha makeup is less prevalent with the new outfit, though it's more apparent with her 2D model. However, she has two strange pill-shaped objects above her eyebrows. These are used to focus her telekinesis better. Yumi uses the Overwing, a hovering scooter, for travel on Lyoko. She usually shares this vehicle with Aelita.

Yumi's main weapons on Lyoko are her dual metal fans or Tessen (Samurai metal fan) that function like razor-sharp boomerangs when thrown. In flight, they turn into fast-moving, saw-like discuses, and also serve as shields to block enemy laser fire. In the fourth season, her fans now appear and disappear at her will (as long as they are in her hands). In the first season she only has one large fan, but in the second season she has two slightly smaller ones. She also has telekinetic powers, though they are difficult to use and exhaust her quickly. However, in the fourth season, her telekinetic abilities are strengthened greatly. She is much more relaxed while using it and can use it in conjunction with her dual fans to telekinetically control the movement of her fans in mid-flight.

Ulrich Stern

Ulrich Stern (voiced by Barbara Weber-Scaff) is the silently-strong introvert of the group, unwilling to talk about himself unless prodded considerably. Ulrich has brown hair. In the first three seasons, he wears a light green shirt with a vest over it and cargo pants, all varying shades of green, and white shoes. In the fourth season, his vest is replaced by a black shirt and army jacket, his white shoes are replaced with black shoes, and his cargo pants are replaced with blue jeans. His night clothes are green boxers/boxer-briefs with a white sleeveless shirt. During the fourth season, the Warriors can be sent to Earth as spectres to destroy XANA's Replika computers. His Spectre form is much like his Lyoko form, except the sleeves end at mid upper arm and the headband is yellow with a white circle on his forehead.

For the 1st and 2nd season he is 13-years-old and in 8th grade. In the 3rd and 4th he is in 9th grade and is 14 in season 3 and 15 in season 4.

Ulrich doesn't say much about his personal life and is evasive when someone asks him about himself or his family. His parents, his father in particular, are very hard to please and have high expectations for their son. He also has trouble expressing his feelings, mainly where Yumi Ishiyama is concerned. He really loves Yumi and tries to express his feelings but Sissi always gets in the way of the both of them. A common theme in the series is Ulrich only admitting to something after a brush with death or an otherwise die scenario. In addition to his troubles with Yumi, Ulrich has to deal with Sissi's affections. Due to her being the daughter of the principal, he is often forced into humoring her in order to get something from her father.

Ulrich sees William Dunbar as his rival in their race for the affection of Yumi and can get often very jealous at him. Although, he doesn't he know that Yumi Ishiyama really loves him but keeps her feelings locked in.

Ulrich's Lyoko attire is modeled after a samurai, minus armor, and he carries a sword. An Oni is drawn on his back and the clothing is largely colored yellow and black. He gets a new outfit in the fourth season, which trades his more loose-fitting clothes for a tighter yellow and brown body suit (similar to William's). A device on his back is traded for his sword sheath, which, in addition to carrying two swords, hides the blades when they're not in use. For travel, he uses a one-wheeled motorcycle called the Overbike, which is also capable of flight.

Ulrich's sword allow him to cut through monsters with ease or deflect enemy laser fire. His speed on Lyoko is enhanced, such that he can deflect even rapid laser fire with relative ease and run faster than most monsters. An additional boost to his speed can be gained through a super-speed running ability (called Supersprint), which can be use to easily traverse long distances, and even cross the surface of water. He can create two clones of himself to aid in battle (called Triplicate), each of which can take one hit before being destroyed. He can bring these clones back together into him (called Fusion). He can also summon his clones to make a triangle around his enemy, (called Triangulate) then attack it when least expected. Both he and Yumi are practitioners of Pencak Silat.

William Dunbar

William Dunbar (voiced by David Gasman) is first introduced in the second season as a new student at Kadic, having been kicked out from his previous school for plastering love letters everywhere,and glueing stickers on the principal's winshield. William has very short, dark and unnatural dark blue hair. William's first outfit consists of a short-sleeved black shirt with a long-sleeved red undershirt, blue jeans and boots. His outfit in the fourth season consists of dark-blue pants, a black shirt with a red logo, and a tan jacket to replace the red undershirt. For the 1st and 2nd seasons he is 14-years-old and in 9th grade. In the 3rd and 4th he is 15 and in 10th grade, just like Yumi.

William serves as a foil for Ulrich, both in his attraction to Yumi and outspoken personality. While Ulrich has trouble sharing his feelings with Yumi, William isn't afraid to assert himself. He spends most of Season 2 and 3 trying to get closer to Yumi, which puts him at odds with Ulrich. He is the secondary antagonist in season 2 and 3 and primary antagonist under XANA in Season 4.

Eventually William learns of Lyoko and XANA, and tries to join the group several times, only to be rejected. William joins the Lyoko warriors near the end of the third season, but is quickly possessed by XANA after he is attacked by the Scyphozoa. XANA then uses William to destroy Lyoko. With Lyoko destroyed and Jeremie cut off from him, William's mind and body is left at the mercy of XANA, who forcibly possesses him to be his servant, giving him a new black XANA-themed suit and powers. From this point until his final freedom, William is helplessly kept under XANA's control, battling the Lyoko warriors. XANA uses William to command his monsters in battles to even the odds. He even uses a unique Manta, which is colored black instead of the standard blue, as a vehicle for William on Lyoko. He is freed from XANA in "Down to Earth", but the group is wary to trust him again. He has no memory of anything that happened during his possession. XANA again possesses him in "Fight to the Finish", and he is once again freed once XANA is destroyed.

In his short appearance in "Final Round", William's Lyoko attire consists of a white and blue form-fitting bodysuit with a red belt. After he is taken over by XANA, his outfit changes to a similar, all-black outfit with red outlines and the eye of XANA on his forehead and chest, as opposed to his eyes. He also gains a spiked gauntlet on his left arm capable of blocking attacks.

As XANA's servant, William's primary ability is smoke manipulation, reflecting XANA's use of smoke-like ghosts in the real world. His weapon forms from smoke and is reduced to such when not in use, which allows him to call the weapon back if they are separated. William can also reduce himself to smoke, allowing him to move at high speeds, and can quickly transform back upon reaching his destination. Finally, he can create smoke in his hands and fire it at his opponents to restrain them, after which he can use the smoke to achieve a limited form of telekinesis on his target. Other powers include hovering and long-range vision.

While possessed, William doesn't devirtualize when dealt enough damage. Instead, he is reduced to glowing red smoke which dissipates into the ground. Additionally, while William usually needs only one successful hit to devirtualize the Lyoko warriors, it takes either several hits or one fairly powerful attack (being cut in half or stabbed in the chest) to do the same to him. It takes one charged energy field to devirtualize William.

XANA

Created by Franz Hopper, XANA (voiced by David Gasman) is a multi-agent computer program and the antagonist of the show. It's a computer program, that has somehow become sentient, and uses its powers of control over anything electronic to cause enough chaos so that it is allowed time to escape the supercomputer. It seeks to take over the world, but often focuses its efforts on the group, seeing as how they foil most of its plans. Most of its attacks tend to be fairly straightforward with little or no warning beforehand. In the first season XANA's attacks are directed mostly at humans in general. From the second season on, the attacks are centered around the group. XANA's favorite targets are Aelita and Jeremie, since they are the two most capable of operating the supercomputer. It is able to cause extreme chaos when it activates a tower, tall cylindrical buildings in Lyoko that, when activated, can give XANA a special ability, until the tower is shut off. Eventually, XANA escapes the supercomputer, and destroys Lyoko. In the penultimate episode of the series, XANA is destroyed once and for all, though Franz Hopper dies in the process.

In all seasons, XANA is represented by an eye made up of a roundabout in the center besieged by two circles. Four tabs occupy the contour of the outermost circle: a longer than others at the top and three other shorter bottom equidistant from each other. The center is a bit wider.

XANA's main power is possession through an energy-based, ethereal "ghost," known as a "spectre", capable of possessing virtually any object and likewise modifying it to almost any necessary end. When a human is "Xanafied" ("Xanatifié" in French) or possessed by XANA, their eyes often have the Eye of XANA symbol (found on all of XANA's monsters) instead of pupils. His own ghosts can also manifest themselves as people without the need for a host as a "polymorphic spectre." Among the common abilities imparted by the ghosts are electricity manipulation, enhanced physical abilities, and apparent invincibility. Additional abilities include phasing through solid objects, self-replication, and technopathy.

XANA rarely speaks or communicates in any way, usually only doing so after he assumes a disguise (like the time he took the form of Jeremie and the two occasions where he took the form of Franz Hopper). He can also speak through the mouths of his "Xanafied" slaves, but he rarely does.

Like the Lyoko Warriors, XANA is opposed to anything it sees as a threat, and on at least one occasion, this has led it to team up with the Lyoko Warriors: in "Marabounta"; it was seen helping the group to protect Aelita from Jeremie's latest blunder, as it needs Aelita for her memory.

Supporting Characters

Waldo "Franz Hopper" Schaeffer

Waldo "Franz Hopper" Schaeffer (voiced by Alan Wenger) is the creator of the supercomputer, Lyoko, and XANA, as well as Aelita's father and Anthea Hopper's husband. He was once a science teacher at Kadic, having been replaced by Suzanne Hertz after his disappearance 9 years ago. He lived at a house near Kadic called the Hermitage with Aelita, and before that had a home in a mountainous region. Franz Hopper built Lyoko and XANA to destroy a military project called Project Carthage, which was designed to disrupt enemy communications. Lyoko was later adapted to serve as a sanctuary for him and Aelita, an apparent result of his suspicions that someone was watching him. Upon fleeing Lyoko, however, Aelita and Franz were attacked by XANA. Franz unsuccessfully tried to reason with XANA, and when that failed he shut down the supercomputer, leaving it inactive until it was found nearly a decade later by Jeremy. He is a minor character.

Franz has gray hair, beard and moustache. He wears glasses and a white lab coat over a long-sleeved sweater in all seasons.

In "Contact", Franz possesses Sissi to try to contact Jeremy. When she is possessed, at first, she seems to be speaking gibberish, but upon further investigation, it is revealed that she is saying backwards, "I can help you. I want to enter into contact with you now, I'm Franz Hopper. I can help you."^[1]

Franz is variously depicted in Lyoko with sphere-shaped constructs. In "Aelita", he is depicted as numerous white spheres, while his appearance in "Distant Memory" is that of a larger purple sphere. Franz Hopper, like XANA, can reach out to the real world through the use of the towers, but not nearly as effectively as XANA can. He helps the warriors at various points in the series, even helping them to recreate Lyoko after its destruction in "Final Round". In "Wrong Exposure", his true name is revealed to be Waldo Schaeffer (the name printed on the folder in the closing credits), while "Franz" is actually his middle name and "Hopper" is his wife Anthea's maiden name. In "Fight to the Finish", he sacrifices himself to give Jeremie's multi-agent system enough power to completely wipe out XANA. The act creates a sense of irony, considering that the majority of the series was spent trying to rematerialize him.

Sissi Delmas

Elisabeth "Sissi" Delmas (voiced by Jody Forrest) is the spoiled, arrogant, and in some ways selfish daughter of the school's principal, Jean-Pierre Delmas, and considers herself to be the most attractive girl in school. She is a former cheerleader, has shown to be a skilled baton twirler, and once used a baton as a striking weapon and a club. She prefers to be called Sissi, and usually becomes angered whenever someone uses her full name - on fellow students, however, she uses physical violence. She is attracted to Ulrich (who has no feelings for her in return) and is jealous of Yumi (whom Ulrich is attracted to). Multiple times, she is seen stalking Ulrich, much to the annoyance of Team Lyoko. Undoubtedly snobbish and a spoiled child, during the first season she only rarely showed a more empathic side. She has lightened up in the second season, and sometimes helps the group achieve victory, though she's not quite aware of the extent to which she helps. She admits in the first season episode "Holiday in the Fog" that all she wants is to be accepted by Jeremy and the others, which she gets in "Echoes" after discovering the factory and making a scene about it. The group uses a return trip to wipe her memory then accepts her to keep her from following them anymore and as a means of thanks for the various occasions she's been of help in the past, with Odd stating that school would be boring without her. It is eventually revealed in the second season episode "Ultimatum" that Sissi took Pencak Silat classes to impress Ulrich, but it didn't work. However, in "Canine Conundrm," her skills in martial arts had been dumbed down significantly. She was originally a member of the gang when they first discovered Lyoko and was intended to join them, but they decided to kick her out after she ratted them out during XANA's first attack. They used the return to the past and wiped her memory of the event and never again informed her of it, certain she would again reveal their secret.

In the first three seasons, Sissi wears a yellow hairband on her head which pulls her long raven hair back. She is dressed in a pink t-sleeved shirt with a yellow heart on it and usually the shirt's hem stops right about an inch above her belly button, which is very ticklish, and a dark pink mini skirt over red/purple trousers with pink shoes. In the fourth season, she does not have the hairband (replaced by two hair clips) and has a pink t-shirt with light blue jeans and red shoes.

William Clone

William Clone (voiced by David Gasman) was created by Jeremy to fill in at school so no one would know that the real William was gone. The clone wasn't very smart though. It had enough common sense not to do dangerous things, and it would answer insults in a very plain fashion, not getting mad as it didn't know what the person meant. It had no emotions aside from confusion and happiness. So it would say the logical answer to jokes. This would often confuse people, occasionally with humorous results, as those around him believed William was playing dumb. He was created By Jeremie Belpois. He is in 9th Grade and is a minor character.

In one episode it was shown to demonstrate rage. The real William, possessed by XANA, returned to the real world and attacked Milly and Tamiya (who had found the factory and were inside the control room at the time) because they got in the way of XANA's plan. During this time the clone protected them using abilities equal to possessed William (super speed and strength etc.), performing well against the original until XANA-William hacked into Jeremy's console and deactivated his program, causing it to disappear.

The first time Jeremy made a clone was in the episode "Double Take" and the clone was of himself to fill in at school so he could work longer. He succeeded activating a tower for the first time. It worked for a while, but XANA-William attacked the tower in attempt to take control of the clone, and the Lyoko warriors, in new suits and weapons that Jeremy had been working on, were sent to stop him. They managed to defend the tower and stop William. Aside from that and having to explain everything to it, the clone of William after that worked just fine. Jeremy later put up a defense program to prevent XANA from further attempts at taking control of the clone.

The only other recorded time XANA took control of the clone of William was in the episode "Wreck Room." Jeremy had written a program to free the real William, but it malfunctioned and bugged up the defense program on the tower maintaining the William clone in the real world. At this point XANA had XANA-William go and corrupt the tower so it (XANA) could take control of the clone. The possessed William did succeed, with a resultant attack on the team in the real world. In the end the team managed to fix the tower and thus the clone. They returned to the past to keep Lyoko and the clone of William a secret.

In the episode "Down to Earth" the team had finally saved real William from XANA returning him to the real world, where William’s parents had shown up for a visit, which wasn't going well. William's parents had become suspicious of the clone due to its strange behavior and abnormally happy disposition, which were opposite of their experience with him. When the team and William got to the clone and William's parents, his dad had just declared that he (the clone) wasn't his real son, as he was too happy and totally obedient. The real William was kicked out of one school because he put stickers all over the Principal's car. The team distracted William's parents and Principal Delmas, and while they weren't looking Jeremy deactivated the clone causing it to disappear. At which point the real William quickly took its place, and acted like himself, getting his parents to calm down and clearing everything up (without anyone knowing about the clone). Jim was the only person who saw the clone disappear, and of course didn't understand what had happened.

William Clone is listed as a supporting character because he is only a copy of a main character, and he is only in the show until the team rescue the real William.

Jim Morales

Jim Morales (voiced by David Gasman in American English and Frederic Meaux in French, also note Jim Moralès in France) is the Kadic physical education teacher, handyman, chief disciplinarian, Pencak Silat instructor and campus/dorm monitor. He has worked at the school for twenty years, as Jim states in Holiday in the Fog. As campus supervisor and PE teacher, his job is to make sure that the children follow the school's myriad of strict rules, but he ends up acting ridiculous and clumsy at every turn; when the students do break the rules or incur his ire, he usually (in a very angry tone) threatens them with some form of disciplinary action, such as grounding Milly and Tamiya to their room in the first episode for wandering into the tool shed when they were only trying to reclaim Milly's teddy bear - however, Milly herself says in the same scene that he believes everything is off-limits to the kids. He is also the prime target for school pranks. When XANA launches attacks against the schoolchildren, his attitude shifts to that of a kind and loving protector. His nickname, as revealed in "False Start", is Jimbo, which is something he claims that his friends used to call him when he was the students' ages.

In addition to his jobs at Kadic, Jim has apparently served under a wide variety of occupations, such as an army soldier and an actor. However, any attempt to get him to elaborate on his past occupations is usually met with his trademark catchphrase answer of "I'd rather not talk about it." He has a nephew named Chris, who is the drummer for the Subdigitals. He also has an interest in Suzanne Hertz, with a few episodes hinting at possible feelings between the two teachers.

Jim is also the only person, aside from William Dunbar and Sissi Delmas, to have known the secret of Lyoko and the gang (for more than a very brief period of time). In one episode, He accidentally gets Jeremy injured during a chase scene. The principal found them and fired Jim. Jeremy and the crew took pity on Jim and told him everything, even allowing him to live in the factory for a short time. He proved to be very valuable when XANA materializes his monsters into the real world, where Jim met them with a nail gun and managed to protect the Kadic students in the real world while the rest of the gang went to Lyoko to deactivate the tower. Afterwards Jeremy did a return to the past which took everyone back to before Jim was fired and erasing his knowledge of Lyoko.

Jim's hair is quite short, Brown, and pulled back somewhat by a sweatband around his forehead. He also wears a bandage on his cheek, which he has never explained. In the first three seasons, Jim wears a white short-sleeved t-shirt, concealed under a dark red tracksuit jacket which covers all his upper body and his belly, along with dark gray jogging pants and brown sneaker. Other than his overweight stomach, Jim's arms are muscular.

Jean-Pierre Delmas

Jean-Pierre Delmas (voiced by Alan Wenger): the headmaster and Sissi's father. He once fired Jim for injuring Jeremie in "Code: Earth", believing that Jim did it intentionally. Odd names his Tamagotchi after him. In the fourth season, he often spends all of his time playing on his computer.

Nicholas Poilakoff and Herb Pichon

Nicholas Poliakoff and Herb Pichon (voiced by Matthew Géczy and David Gasman respectively) are two teenage boys who also attend Kadic Academy. They both follow Sissi Delmas around acting like her "pets". Although it is clear that Herb Pinchon has deep feelings for Sissi, it is clear that she does not feel as strongly. Rather, she tends to keep them around when she needs company, but as soon as Ulrich and his gang show up, they are thrown away.

Herb Pinchon is rather smart and it is revealed that he has Claustrophobia in the episode "Claustrophobia". He is voiced by David Gasman.

Nicholas is also a very talented drummer as seen in Episode 2 of Season 1 when he wants to join the Lyoko Warrior's band. He is voiced by Matthew Géczy.

Kiwi

Kiwi (voiced by Barbara Weber-Scaff) is Odd's dog, who boards with him at Kadic academy, even though dogs are not allowed. Kiwi once was possessed by XANA in the episode Attack of the Zombies; he traveled around the school and infects various students and teachers by biting them and turning them into zombies. Ulrich also went into Kiwi's body in "Nobody in Particular".
