description

Ulrich is the tallest male of the group (tallest group member being Yumi), with scruffy-looking dark brown hair and dark eyes. In the first three seasons, he wears a vest with a shirt over the top and cargo pants, all in shades of green, with trainers. After season three, his outfit changes to a dark green shirt, army jacket, and blue-gray jeans. Ulrich's original Lyoko form is similar to a Samurai. His outfit has a Hannya mask on his back, which is used in Japanese Noh theater to represent a jealous female demon. He also has a single Katana sheathed on his left hip. In the fourth season, this changes to a form-fitting yellow and brown body suit. He also gets a second Katana and they are both sheathed on his back. He comes from a privileged background as the son of upper middle class parents and (as briefly mentioned in the episode Routine) possibly receives a large allowance each month.[1] However, unlike Sissi, it appears that Ulrich rejects the snobbery of the upper classes. Ulrich lives on the Kadic Academy campus, sharing a room with his friend Odd and Odd's dog, Kiwi. Although he is a fairly withdrawn individual, he has a fair amount of friends and is even the object of affection for many girls in the school - mainly for his looks, athletic ability and alluring personality. The most notable is Sissi, who has had a strong affection for Ulrich since grade school and is the most persistent of his admirers, often leading to trouble for the rest of the gang. His strong feelings for Yumi, however, keep him from pursuing any other romantic attention and to frequently reject Sissi's many romantic offers. On Lyoko, Ulrich is an extremely effective warrior and is often known to be the best fighter among the group, which is shown in several episodes. With his saber, he can destroy any monster in close combat as well as deflect attacks. He is the only person whose abilities are short-range only, "since William also has Super Smoke." Ulrich is most notably passionate about martial arts and practices Pencak Silat (an Indonesian combat style permitting to strike any opponent), which becomes a great asset for him when defending against X.A.N.A.'s plots on both the real world and Lyoko. However, he trains harshly in all athletic pursuits, especially soccer, as shown in Zero Gravity Zone. He is probably the most dangerous of the gang in both worlds, and not one schoolboy, even the strongest one, dares to attack him. He is in 8th grade for Seasons 1-2, 9th through Seasons 3-4, and 10th as of Evolution.

personality

Ulrich is the introvert of the group, rarely expressing his feelings and acting evasive whenever someone asks him about himself or his family. He seems to have trouble opening up to people and hides his feelings in order to use them all the more explosively in action. One of Ulrich's key characteristics is his affection for Yumi, a fact that has caused countless instances of tension and drama between the two of them due to the fact that he has never admitted it. Even his friends have occasionally admitted to finding his hesitation tedious, and the constant excuses Ulrich makes to himself are only underlined by his jealousy whenever Yumi spends is approached (or is seen approaching) anybody else. In rare instances, his feelings for Yumi can cloud his better judgement by making him pull reckless stunts in her favor. One time was in Marabounta when he humiliated himself by falling off the diving board in an effort to spy on her when she was with William. A more notable time was in The Chips are Down when he became so worried about Yumi moving away that it resulted in his temporary expulsion from the team when he went behind his friends’ backs to launch a Return to the Past (which strengthens XANA) to cheat at the lottery and donate the winning ticket to Yumi’s parents. Ulrich behaves childishly whenever he is beaten or humiliated in her presence, refusing to congratulate Yumi after she tied him in a fight in X.A.N.A. Awakens and getting mad from embarrassment after William helped him out of the pool in Marabounta. This implies he has a massive inferiority complex which, combined with his ability to constantly make excuses for himself, often prevents him from maturing or gaining self-confidence. He also is known to take it out on others, including one time he played a rather cruel joke on Johnny, a younger classmate, just because he admitted to Ulrich that he liked Yumi (in The Pretender). This inferiority complex is also enhanced by Ulrich's extremely strict and condescending parents, particularly his father, who Ulrich has had the least stable relationship with anybody else due to his inept laziness when it comes to his schoolwork. However, in times of crisis Ulrich is able to drop these feelings of inadequacy for the sake of his friends. He is brave and extremely competent on the battlefield (both on Lyoko and Earth), and is also shown to be unwilling to let anyone, even his rivals or bullies, get hurt by any of X.A.N.A.'s attacks. Ulrich becomes incredibly worried whenever his friends are hurt, and it is during these times that his feelings tend to surface. The first example of this is in the episode Killer Music, when Odd is sent to the hospital in an emergency condition and slips into a coma. Ulrich blames himself for not being there when Odd had needed him and insists on riding with him during the ambulance ride despite protests from the principal. A similar situation occurs in the episode Cold War, when Yumi is trapped under a fallen tree during a deadly blizzard. After several failed attempts to free her, he cries as he tells her that he needs her while holding her and screams in grief when she appears to have died. In Vertigo, it is revealed that Ulrich has vertigo, which is a chemical disorder that causes dizziness in the presence of high altitudes. He shows signs of it when attempting to climb a rock wall in the gym, which reveals the condition to his friends. This condition doesn't seem to affect Ulrich much before this point, except for in the prequel, when he hesitates to slide down the ropes to the factory floor. Having vertigo does not seem to be a hindrance on Ulrich when on Lyoko, with the notable exception of the episode Bad Connection. In Echoes Ulrich admits to Odd that he likes being a hero, implying that he sees his time on Lyoko as a way to prove himself.

Relationships

Yumi Ishiyama "You're the person who means the most to me." –Ulrich to Yumi in Intrusion Ulrich is shown to have had an instant romantic attraction to Yumi as seen in the two-part prequel, X.A.N.A. Awakens. Ulrich is seen eyeing Yumi as she gets a drink from the vending machine and noticeably watching her as she passes by him and leaves. He can be seen checking her out yet again when he first officially meets her in his martial arts class with Jim, later bonding with her over their shared interest in Pencak Silat. He has a close relationship with Yumi, based on observation from a distance and repressed admiration, though both he and Yumi constantly waver between being just friends or more than that. Early in the first season, Ulrich admits to Odd how he deals with insecurity in his confusing relationship with Yumi, often questioning how she truly feels about him and at times left to believe that she doesn't feel the same way about him as he does her. Nonetheless, his feelings for her can sometimes cause him to do things that might be considered stupid. For example, in Saint Valentine's Day, he writes a poem for Yumi for Valentine's day after forgetting about the holiday. However, when he sees Yumi with William, who was giving her a bouquet of roses, he reads the poem to Sissi instead in order to make Yumi jealous. This only backfires when Yumi, becoming jealous, sweetly thanks William for the flowers telling him he "couldn't have made her happier" before topping it off with a kiss on the cheek. This earned a glare and scowl from Ulrich. He later admits that he actually wrote the poem for her, making her smile. He and Yumi finally confront their feelings for each other in Routine, where the two even nearly share their first kiss together (before getting interrupted when a return to the past takes place). The two decide to keep it a secret from the rest of the group. However, it seems as though Odd possibly knows about it when he asks Ulrich at the end of the episode, "It wasn't all that boring on Lyoko was it, Ulrich?" Ulrich replies by saying, "You're right, Odd. I learned something too. Something super important." Ulrich has the habit of getting easily jealous whenever he sees Yumi with any other 15-18-year-old male that is not Odd or Jeremie. When he does see Yumi with another boy he becomes obsessively jealous and starts to question his and Yumi's relationship. Odd even remarks in The Pretender that Ulrich gets jealous when his dog Kiwi looks at Yumi for a moment too long. Ulrich also becomes extremely competitive (as seen in Marabounta) when it comes to winning over Yumi. Ulrich also has the habit to become extremely protective of Yumi when she is in danger usually by cradling and holding her in his arms or by screaming her name when she is unconscious; this can be seen in Cold War when Yumi shoves Ulrich out of the way of a falling tree during a blizzard and takes the impact herself, Ulrich decides to stay with her to keep her from falling asleep and, when unable to get her out and she begins to fall asleep, he begins to cry as he says that he needs her. When Yumi eventually falls asleep, possibly dead, he screams in distress (although Yumi is saved thanks to a return to the past). In The Chips Are Down, when it looked as if Yumi and her family might move back to Japan because her father lost his job, Ulrich actually tries to write a letter to the president in an attempt to at least keep her near the school when finding out her parents would never allow her to become a border. He abandoned this plan once he heard the lotto numbers being announced on the radio. Instead, he copied the winning numbers and activated a return trip, despite knowing by then that return trips make X.A.N.A. stronger, in order to buy a lotto ticket and give it to Yumi's parents, allowing them to win the lottery. This action temporarily cost him his position in the group, and he was banned until they could think of an appropriate response, although he is later let back in at the end of the episode and he apologizes for not checking in with the group first. In Straight to Heart, Yumi talks with Ulrich about their romantic relationship when she says they always go around "in circles" with their relationship saying how "one day they're together, the next day they're not, one day he's jealous and the next she is" and says that they need to clear up their relationship once and for all. She then declares they can be friends, but nothing more on a strictly platonic level. This, in which, clearly horrifies him. However, he begrudgingly goes along with it, though it obviously upsets him. Even after this, however, Ulrich still shows through his actions that he still considers them to be more than just good friends, although he insists they are nothing more than such. In Tidal Wave, after saving Yumi's life, he tells her that he would do anything for her. He also shows respect for her Japanese customs, such as in Distant Memory where the group was exchanging gifts and he and Yumi didn't open theirs, Odd noticed and asked about it. Ulrich explains how in Japan a person doesn't open their gift in front of the person who gave it to them. He then side glances at Yumi while blushing, who winks and smiles at him. Also, in Kadic Bombshell, when Odd and the group talk about love after a classroom reading of Romeo and Juliet, Odd teasingly asks Ulrich if he'd be willing to die for Yumi. This leads Ulrich to accidentally, but firmly, say "Better believe it" before blushing as Yumi came up to join them. Furthermore, in The Pretender, Ulrich tricks a boy named Johnny, who has a crush on Yumi, into embarrassing himself in front of Yumi, because he couldn't stand the idea of anyone else going out with her (although Johnny was far younger than Yumi, it still upset Ulrich that he liked her at all). Later in the series, when Odd playfully teases Ulrich about his relationship with Yumi, he defensively shouts, "Yumi and I are just good friends and nothing more!" and when Odd asks, "Are you sure?", Ulrich admits he actually isn't sure what he and Yumi are. In Echoes, it is hinted at that Ulrich and Yumi finally start on re-exploring their deep and close romantic relationship after the Supercomputer is shut down. In Code Lyoko Evolution, which takes place one year after the fourth season finale, it is shown that Ulrich has fully accepted his strong romantic feelings for Yumi by openly saying to Odd that he loves her and even refers to her as the "love of his life". After some encouragement from Odd, who had been urging him to finally admit to his romantic feelings for her, he struggles to find a way to tell her. He makes two attempts in the episode to tell her how he really feels about her, only to get interrupted each time. The next few episodes hint at their attraction, with Ulrich sometimes getting jealous over William spending time with Yumi (this being seen in Rivalry), getting protective over her (How to Fool X.A.N.A.) and such. In The Warrior Awakens, when Ulrich can be seen dreaming, the ending of the dream before he wakes up is shown to be many thoughts of Yumi. In Intrusion, which takes a small focuses on their relationship, the two get into a fight when Yumi, upset at him for failing to keep a promise to her, angrily writes about him in an essay paper (under another name) in a negative manner about how he is "immature and stubborn" and doesn't care about anyone else. Ulrich is hurt about her harsh words directed at him and confronts her about it, demanding to know if that is really how she sees him. Despite her claim that it was only an essay paper, he decides to leave on a group mission to be alone and calls for a break in their friendship. He retreats to his room where he spends his time there dejected and depressed. Yumi soon becomes guilt-ridden after this and decides to apologize to him at Kadic in his dorm, intentionally getting herself devirtualized on an important mission with the group to see him. However, he refuses to open his door to her but soon ends up chasing after her when she leaves after admitting the boy in her essay was, in fact, about him. In the forest, he still remains hurt about her words to him and Yumi is annoyed that out of all the good things she wrote about him, such as his depth and sensitivity, he can only focus on the negative. She calls him out for never being there when she needed him and being so touchy. She then says how she purposely got herself devirtualized in order to see him because she couldn't stop thinking about him. He then admits to her that he should have been there for her for many things and that she is the most important person in his life to him and he doesn't want to lose her, promising to make an effort from now on. Yumi admits the same goes for her about him and the two share a moment, smiling at each other. In Massacre, when Aelita asks Yumi about her relationship with Ulrich, Yumi describes things as "cool". When pressed for details, Yumi admits that things are going much better between her and Ulrich since he has become "more considerate towards her feelings", fights less with William and is much more mature than he's been in the past, making her happy. Odd Della Robbia Ulrich's best friend and roommate. At first, as seen in prequel, he and Odd didn't get along well due to their polar opposite personalities. However, as a result of being roommates, they soon began to mend a friendship after hanging out together for a while. This, in which, only grew in strength and Odd soon becomes Ulrich's best friend. Being his closest and best friend, Odd seems to know more about Ulrich's private life that any of the other characters, such as his relationship with his parents (as seen in Zero Gravity Zone) and Ulrich even trusts Odd to get Yumi's birthday present for him when he forgot about it and couldn't buy one himself due to having to serve a detention (Lab Rat). Although the detention was, in fact, on account of Odd himself. Although the two didn't get off to the best start, as seen in the prequel, Ulrich soon grows fond of Odd, worrying about him when he's hurt in Killer Music and has to be sent to a hospital. He even becomes guilt ridden and blames himself for the whole mess since he had yelled at Odd the night before and left to go study for a test. Because of this, he felt like he had failed to be there for Odd when he needed him the most. Ulrich has even been willing to take the blow for Odd, covering for him during a prank as seen in Cold Sweat. This is when Odd gave Milly and Tamiya an old picture of Yumi in an embarrassing Halloween princess costume from when she was little. Ulrich (reluctantly) agrees to say it was him who posted the picture when Yumi comes to angrily confront Odd about it. This action ended up briefly costing him his friendship with Yumi, who felt betrayed, and caused Ulrich to demand that Odd tell her the truth - vowing to do so himself if he didn't. Feeling guilty and like a coward, Odd later admits the truth for Ulrich's sake with Yumi. The devotion to his friendship with Odd cannot be said for his relationship with Kiwi. However, since he spends more time moaning to Odd about him than not. Odd is always there for Ulrich, offering him advice whenever he needs it. He often teases him about his relationship with Yumi, dubbing them "The Love Birds", often earning a glare from Ulrich much to Odd's amusement. Odd often tries to genuinely push the two together, knowing how difficult it is for Ulrich to admit his feelings for Yumi due to his low self-esteem and confidence. Jeremie Belpois Ulrich and Jeremie have become very good friends throughout the series. Although the two had scarcely spoken before the incident with the supercomputer, they learn to trust each other as the need to defeat X.A.N.A. appears. There are a lot of times where Jeremie gets impatient with Ulrich, especially his tendency to withdraw himself (as seen in Zero Gravity Zone), but he knows to trust him to come through in the end and vice versa. Aelita Schaeffer Ulrich's relationship with Aelita can be compared to that of siblings, specifically that of a big brother and younger sister. This is mainly due to how he spends a lot of time protecting her from danger on Lyoko and treats her in a brotherly fashion. He takes to occasionally call her "Princess". Aelita is shown to have a sincere kindness to him like that of a sister. Some examples of this are when Ulrich possibly vanished without a trace in Nobody in Particular and she cried herself to sleep and being the only one to sympathize with him in The Chips Are Down when he was kicked out of the group and gave him a comforting gesture before walking away from him. William Dunbar "I don't wanna see you hanging around Yumi ever again!" –Ulrich in Fight to the Finish. Ulrich and William have been rivals since his arrival at Kadic academy on account of his blunt and open feelings for Yumi. Ulrich can be seen instantly disliking William the moment he saw him - literally - during a class science project in the episode New Order, where William was Yumi's partner. He spies on the two throughout the project, thinking that William was "completely snowing her." Ulrich had been distrustful and hated William ever since then. However, in The Secret, after he manages to save the factory from a bomb with William's needed help, Ulrich sees William's potential to be a valuable asset of the team. When the group takes a vote as to whether or not let William join the group, he votes yes. Despite this good moment, they are still bitter rivals due to William still making advances towards Yumi. However, in Code Lyoko Evolution, the two eventually learn to make something of amends in Rivalry, when William saves Ulrich from falling into the Digital Sea. They still occasionally bicker throughout the series, but have since formed something of a friendship together. It seems that William has now seen that he will never have a chance with Yumi and has given up on her, making his friendship with Ulrich much easier. Sissi Delmas Sissi and Ulrich's relationship is complicated. She has had a crush on Ulrich since elementary school, creating a love triangle of a sort. At the same time, Ulrich doesn't reciprocate her more-than-friendly feelings given Sissi's annoying personality. Ulrich has manipulated her feelings towards him on numerous occasions and sometimes used them to his advantage to help the group out during Lyoko missions. This happened when Yumi's Digital Genetic Code was stolen in Missing Link and he needed her help to ensure Yumi wouldn't get suspended for not being at school along with other incidents. In one specific act of desperation, in Frontier, Yumi was in the principal's office after getting into trouble with the staff (in an attempt to get Jeremie's laptop after accidentally sending him to the limbo of Lyoko), he reluctantly kissed Sissi in order to get Yumi out of trouble. Odd enjoyed teasing Ulrich about this afterwards, who demanded that he never tell Yumi about it and that it never be brought up again. On the other hand, Sissi has blackmailed the Lyoko Warriors on more than one occasion, usually via Ulrich. Ulrich is aware of the better parts of Sissi's personality due to her true caring nature being revealed whenever a X.A.N.A. attack takes place, this usually resulting in him being nice to her for a little while. However, he is still shown not to be romantically interested in her and ultimately always prefers Yumi over her, much to Sissi's frustration. The two had a reconciliation of sorts in Echoes, though it was after she attempted to stalk Ulrich. Their love triangle created a strained relationship with Theo and Herb. In Evolution, it appears that she has stopped romantically pursuing Ulrich and is on genuine good terms with the group. Mr. and Mrs. Stern A significant trouble of Ulrich's are his parents, particularly his father, who are very hard to please and have high expectations of their son. In Zero Gravity Zone, Jeremie berates Ulrich for choosing to participate in an upcoming soccer game instead of helping to fight X.A.N.A., yet Ulrich does not retaliate or change his mind. After Ulrich leaves the room, Odd explains that Ulrich doesn't want to disappoint his parents, especially his perfectionist father who is a businessman. He further says how Ulrich feels that his talent at sports is his only way of being able to please them given his poor academic performance. A few clear examples of his bad grades are when he receives a D- on a science test in Nobody in Particular and then later receives an F+ on another test in Double Trouble (the plus being added "so he can do worse next time"), despite having tried his sincere hardest to get a passing grade. His struggle academic wise is shown to often get to him and he is occasionally shown studying hard for an upcoming exam and being upset when receiving a failing grade. His bad relationship with his father based on his poor grades is shown in Final Round. Ulrich's father unexpectedly shows up at Kadic to talk to Ulrich just when he starts getting his grades up and berates him for his failing performance in school, a scolding that Ulrich takes despite being emotionally hurt. His father even resorts to insulting his friends and accusing them of being a bad influence (despite having never met them). However, Ulrich finally snaps when his friends (in essence, his family) are insulted and yells at his father since he doesn't know him and hasn't even talked to him in a year. The second his phone beeps on account of an emergency on Lyoko, he then angrily leaves the room despite his father yelling at him to sit back down, declaring that he is done listening to him. Despite all this, Mr. Stern reveals to Ulrich in Zero Gravity Zone that he is proud of him, right before the return to the past wiped the event from his mind. Others Emily LeDuc, Milly Solovieff, and a few other characters have expressed romantic interests in Ulrich at various points. Most of this happened in Season 1. Skills Martial Arts On Earth, Ulrich is a capable martial artist trained in the art of Pencak Silat (in Evolution, this is changed to him knowing Karate). At least part of this training is from his PE teacher Jim (presumably a great martial artist himself, although he'd rather not talk about it), as shown in X.A.N.A. Awakens, Revelation, and Canine Conundrum. He's also capable with a sword, which is his main weapon in Lyoko. He demonstrates this talent outside of Lyoko in A Bad Turn when protecting Yumi from a materialized Krab using a real katana, and in A Great Day when using a pipe to sword-fight with a possessed Sissi. As evidenced by a quote by Ulrich in Rock Bottom?, he also practices other martial arts. In Revelation, he copies the famous nose-wiping and hopping stance of martial arts movie star Bruce Lee during his battle between himself and a polymorphic clone that had transformed into a dark version of Ulrich. Ulrich has, on several occasions, shown to be the most skilled in Lyoko when fighting. Many times he has defeated multiple monsters with skillful takedowns (particularly in the third season), and has outlasted the others, usually being the last to be devirtualized, such as in the episode Code: Earth. In Revelation, Ulrich is forced to face off against a polymorphic clone of X.A.N.A.'s while in Lyoko. In the beginning, he is shown taunting the clone (which at the time had taken the form of Odd) by saying that Odd had never beaten him yet. This implies that Ulrich is definitely stronger than Odd. Then the clone transforms into a clone of Ulrich, making it an even match. After a long fight and an impressive display of swordsmanship and martial arts, Ulrich beats the clone, showing once again that he has impressive abilities. Also, in Fight to the Finish, he manages to kill the Kolossus, a powerful fiery Kaiju-like creature, created by X.A.N.A. by drawing energy from all the Replikas. However, its corpse fell on him, devirtualizing him instantly.

skills and powers

Weapon: Katana - Ulrich uses a thin katana/saber as his weapon in Lyoko. Ulrich use it to slice or stab enemies. His katana is capable of absorbing normal laser fire and can deflect it if positioned correctly. However, he cannot block specialized attacks, such as a Megatank's elliptical laser or a Blok's ice beam. The latter may simply be a matter of timing, as the Bloks tend to catch Ulrich off-guard when using that attack. The Megatank's elliptical laser, on the other hand, has proven to be too much for Ulrich to handle, due to the sheer amount of force behind the attack. Ulrich can only block the attack for a short period of time and the katana is always devirtualized along with Ulrich himself shortly afterward. Ulrich's katana can also be destroyed through a barrage of regular laser-fire (as seen in The Pretender). In Double Take, Ulrich is upgraded with a second katanas, which are simply called Twin Blades. Also, Ulrich would seem to be an expert with the sword since he once stated "I could do the same thing when X.A.N.A. attacks in reality." In Franz Hopper, Ulrich‘s sword was temporarily upgraded with a slash beam, an attack where he could supercharge the sword to fire wide saw-like lasers when swung. Ironically, this would become William’s signature move with his own sword. Lyoko Powers: Super Sprint - Ulrich has prominently demonstrated to be a speedster on Lyoko, leaving a glowing yellow strip of light trailing behind him, but in Evolution the speed trail color changes to blue. Triplicate - Ulrich can deploy two identical hyper-realistic holograms of himself to divert X.A.N.A.'s monsters which appear to be controlled by Ulrich through telepathy. The clones have every ability he does, with the exception of cloning themselves and are only able to take one hit before being destroyed, and are automatically destroyed should the real Ulrich be devirtualized. When using this power, Ulrich simply creates the clones as assistants. At first, Ulrich's control of these clones seemed rudimentary at best, since they would often be easily hit. As the series has progressed, his control of them has refined. In the episode Tip-Top Shape, he was able to use his clones to fight three groups of monsters (a Krab, a Blok, and three Kankrelats) without losing a single clone to his opponents. He even toyed with the final Kankrelat, having one of his clones kick it into the air so he could strike it in mid-flight like a baseball. The clones can also be recalled and drawn back into Ulrich in a process called "Fusion". Triangulate - Ulrich and his two clones form a yellow triangle around their target. A silhouette of Ulrich then runs around the perimeter of that triangle, forming a golden barrier. This is meant to confuse the target so Ulrich can destroy it. After the technique is finished, any remaining clones revert to their assistant state. Enhanced Reflexes - A superhuman ability that enables Ulrich to sense whenever lasers are coming near him from behind, and dodge them with ease. Vehicle - Overbike: The Overbike is as fast as Ulrich while using Super Sprint. Ulrich also has a Nav Skid that can shoot torpedoes on since Season 4.

Lyoko

Lyoko Lyoko (pronounced either l'yoh-koh or lee-oh-koh), sometimes spelt Lyokô,[1] is a virtual world, contained and accessible by a Supercomputer within the Factory. It was designed by Franz Hopper, as a means of digitally representing and accessing the abilities of the Supercomputer. The world is divided into five Sectors, all with their own unique features. Each sector is isolated from the others by a physical representation of the Internet known as the Digital Sea. A sparse, unpopulated world, the most notable landmarks on Lyoko are the Towers scattered around it; twenty-one in each main sector and only one in Sector Five.[2] These towers act as data processing nodes, pathways to the real world, and safe havens for those on Lyoko. towers The towers serve as data processing nodes for the supercomputer, and as a link between Lyoko and the real world. By infecting these towers (usually one at a time, but sometimes more) X.A.N.A. can attack the real world. Aelita, Jeremie, and Franz Hopper can operate the towers in the same manner, but not anywhere near as fast and skillfully as X.A.N.A. can. X.A.N.A. can take over towers activated by Jeremie, and Franz can do the same with both Jeremie's and X.A.N.A.'s towers. Aelita is capable of deactivating any activated tower by entering the Code: LYOKO, in the interface inside a tower. Throughout the four main Sectors, giant wires wind their way out from the 5th sector to each of the towers in each of the Sectors, acting as conduits for data. Red energy can be seen pulsing through these wires whenever X.A.N.A. activates a tower, and pulsations follow the wires along the ground. These wires can be severed. In Code Lyoko Evolution, Odd, Ulrich and Yumi are now also capable of using towers as long as they have their source codes. Benefits Because those on Lyoko are digital rather than organic, they do not age. A clear example of this is given with Aelita, who spends nearly a decade on Lyoko after arriving there around the age of 12. She does not age at any point during that time, though her voice and intelligence change significantly in her slumber. According to Jeremie's explanation of the five senses in Cruel Dilemma, those on Lyoko have two: sight and hearing. However, other episodes have shown that Odd, Ulrich, and Yumi have the other three senses (taste, touch, and smell) to a certain degree. desgin Lyoko was designed by 3D scenery director Eric Guillon based off the original concept Garage Kids.[6] The design of Lyoko came after a long series of discussions with director Jérôme Mouscadet, who said "[...] to be able to create layouts rapidly, we would make something LEGO-like, with plates, that are the sectors: desert, mountain, and so on; and then have a number of specific building blocks such as rocks, trees for the forest sector for instance, that we could arrange rather rapidly[.]" This choice was partially due to budgetary reasons from the series being produced in France, with him explaining "[...] it’s so expensive to do shot-based layout, that is create an image for each shot, that it immediately becomes like a full-length movie and you explode in mid-flight[.]" Various films were used as reference while designing the sectors.[7] The Forest Sector took inspiration from Princess Mononoke, while the Mountain Sector drew from Mulan and Crouching Tiger, Hidden Dragon, and the Desert Sector was influenced by Lawrence of Arabia. When it came time for the second season, Mouscadet said they wanted to "go to the center of Lyoko" and created a fifth sector to achieve this.[8] The four original sectors had always rotated on the holomap from Guillon's initial concept art, so they "decided that the central sector could only be spherical". The layout of the rooms in the sector were gradually decided afterwards. history After Franz Hopper left Project Carthage and went into hiding, he built the supercomputer and created Lyoko to serve as a safe haven for him and Aelita from his enemies within the government.[2] He split the Keys to Lyoko between himself and Aelita, which would make the pair the absolute masters of Lyoko. According to his diary, he then lastly created X.A.N.A. to destroy Project Carthage: a military project designed to block enemy communications. The government eventually found him, forcing him to flee to Lyoko with Aelita. Upon reaching Lyoko, Aelita and Franz were attacked by X.A.N.A. Franz had tried to reason with X.A.N.A., but was unsuccessful. As a last-ditch attempt to stop X.A.N.A., Franz shut down the supercomputer, and it remained that way for nine years. Once it was reactivated by Jeremie, X.A.N.A. took complete control of Lyoko and used it to attack the real world. Two weeks after his escape from the supercomputer during The Key and creating Replikas of Lyoko's sectors in different supercomputers across the world, X.A.N.A.'s new goal was to destroy Lyoko itself in order to prevent the Lyoko Warriors from fighting it on the network but more importantly to finally destroy the biggest threat to its plan for global dominance: its own creator. Knowing that Franz Hopper was still on Lyoko somewhere, X.A.N.A. immediately targeted the Core of Lyoko at the heart of Sector Five but after being stopped by Aelita's new powers, instead thought to delete each of the surface sectors one-by-one to prevent them from accessing Sector Five. It did this by possessing Aelita using the Scyphozoa and forcing her to enter the Code: X.A.N.A. in each sector's Way Tower. During the events of Finale Round, X.A.N.A. took advantage of the team's newest member, William Dunbar and possessed him in order to destroy the Core, resulting in Lyoko collapsing upon itself, leaving only a X.A.N.A.-possessed William in his wake. Franz Hopper, who managed to escape Lyoko's destruction, was able to send a coded message to Jeremie and Aelita with instructions on how to restore the entirety of Lyoko. In Season 4, X.A.N.A. still kept attempting to destroy Lyoko after its restoration, and attempted to sabotage the team anyway possible in order to prevent them from catching up with his plans. When recreating Lyoko, Jeremie and Aelita deleted the keys from Sector Five and added a hangar for the Skidbladnir. X.A.N.A. later met his doom at Lyoko as Jeremie launched a program that could destroy him once and for all. Sectors of Lyoko The first Sector in numerical order is the Ice Sector. The others are numbered counterclockwise starting from the first. Sector Five is the fifth sector (See Sectors for more info). Ice Sector Icelocation Ice Sector in Holomap. True to its name, the Ice Barrier (also known as the "Glacier Region" or "Polar Region" in Season 1) is cold and icy. Composed of large glaciers and thin paths covered in a thin layer of snow, the Ice Sector is just as slippery as any ice-covered area in the real world. While not dark, there is no visible sunlight in this region. Many of the towers in this sector are only accessible through various caves and tunnels, which sometimes forces the group to slide through the tunnels to reach their destination. Additionally, in the episode The Girl of the Dreams, Odd mentions that Aelita may be "in a storm or snowbound," referring to a blizzard, but this phenomenon has yet to be observed in any episode. Simulated water (not to be confused with the Digital Sea) exists in this sector, and like actual water, can be swum through. X.A.N.A's monsters have proven to be less than proficient swimmers, as four Tarantulas drowned in the Temptation. Odd on the other hand has no trouble swimming through the water in Vertigo. With enough speed, Ulrich can run across the top of the water. This is the only sector X.A.N.A. was unable to delete in Season 3. Though he manages to possess Aelita to do so in an episode prior, it is Aelita herself who willingly deletes it in a Pyrrhic victory in Sabotage so Jeremie could repair the supercomputer. After X.A.N.A's death and mysterious return, it was revealed that the Ice Sector had disappeared. Desert Sector Desertlocation Desert Sector in Holomap. The Desert (like any desert worth its name) is dry and sandy as far as the eye can see. It has an oasis, but the water stored there is just an illusion. It leads to a lower platform. The biggest danger is falling off the edge (plateaus are rather small here) and into the Digital Sea below. The Desert is very sunny, reflecting the bright and dry climate of regular deserts. X.A.N.A. has the ability to create sandstorms in this sector (only seen in Log Book), as well as tremors that cause the plateaus to break apart. Additionally, in Plagued, X.A.N.A. was able to tilt a plateau to a 90 degree angle. Aelita, Odd, and Ulrich were on the plateau at the time and would have fallen into the Digital Sea had Aelita not used her Creativity to save them. The Krabes were able to traverse the tilted plateau easily thanks to their scythe-like legs. Megatanks are the least proficient in this sector, as their high speed causes them to fall from the plateaus in this Sector. However, the craggy rocks in this sector enable them to easily wage a sneak attack. Forest Sector Forestlocation Forest Sector in Holomap. Mystery reigns in the enchanted-looking Forest. Graceful trees, suspended in mid-air, let their roots dangle into the Digital Sea. The Forest can be considered the most beautiful of the 5 Sectors. It also has narrow paths rather than plateaus, though the chance of falling into the sea here is less than in the Desert. Despite that, this is not the only Sector where someone has actually fallen into the sea. Yumi has fallen in the sea in Cruel Dilemma. The trees also provide excellent cover, which can lead to traps. Like the Ice Sector, there is simulated water in this sector, but in a much smaller quantity. The Forest is typically bright, but not as much so as the Desert. The Forest noticeably changes in the transition between Seasons 1 and 2. In the Season 2, it is far brighter than before, appears to have more trees, and has larger land masses than it previously had. Throughout the series, the Forest Sector serves as the center of Lyoko's plot-related events. In an episode a tower was in the middle of some simulated water. However, this was never shown again. After X.A.N.A's death and mysterious return, it was revealed that the Forest Sector had disappeared. Mountain Sector Territoire Montagnes clip image006 Mountain Sector in Holomap. Its peaks craggy and its stones sharp, one false move in the Mountain and the group will topple off the rocks into the gaping void beneath. The Mountains are full of moving platforms and tricky obstacles, and is known for having further platforms underneath the "cloud cover," obscuring the Digital Sea in some areas. These clouds make it difficult to aim oneself onto the lower plateaus. X.A.N.A. can extend and thicken the fog. If one of the warriors falls a sufficient distance, regardless of whether or not they land properly, 20 life points are lost on impact. Though not dark, no sunlight is visible in this sector, as the cloud cover obscures it. This is the last Sector to be deleted in Double Trouble. Being mostly empty sky, the Hornets have the advantage over the group in this sector. In contrast, the narrow paths discourage the use of Megatanks in this sector, since falling off of the edge is quite easy. However, the Megatank's attack makes them effective blockades on narrow paths, since one Megatank can effectively cover a tower on its own without having to worry about retaliation. This is the 2nd and last Sector to be turned invisible in Tip-Top Shape and because of this, Yumi almost fell into the Digital Sea. Sector Five. Sector Five is hidden deep within Lyoko that was accidentally discovered in Uncharted Territory. Initially, it's only accessible by the special password SCIPIO (from Scipio Africanus, who defeated Hannibal of Carthage in 202 B.C.). This summons the Transport Orb to the edges of the other sectors furthest from Sector Five to carry its passengers to the Sector's core, called the arena. At the end of Double Trouble, immediately after the Mountain Sector had been deleted, Jeremie finally developed a program allowing him to virtualize the warriors directly into the sector. Sector Five is the very core of Lyoko itself, with only one normal tower instead of the standard twenty with an additional Way Tower. The Sector itself is shaped as a giant blue sphere. On the outside surface of the sphere is a barrier covered with images of binary code similar to those seen in the towers. Floating in the middle of the Sector is the main body of Sector Five — a smaller, but still massive, blue orb. 4 data streams feed from equidistant points on its surface to the 4 other sectors. Everything in Sector Five is blue and geometrically shaped. In this Sector, the Digital Sea has been replaced by a data barrier similar to the ones in the towers, but falling into it seems to be just as bad as falling into the sea. The interior of the orb is an ever-changing maze, designed to act as a security feature to prevent intruders from finding their way around. The interior rooms and corridors of Sector Five are composed of planes, cubes, and rectangles that can slide freely over, around, and against each other. Therefore, this Sector can reconfigure its topography at will. Upon accessing Sector Five, the labyrinth will reconfigure into a random pattern and a 3-minute countdown will begin, allowing whoever enters to try and traverse the labyrinth and disable the security system. The security system is disabled by pressing a X.A.N.A.-Eye shaped switch (called a "key") somewhere within Sector Five. Like the rest of the Sector, the key is moved with each visit. Failure to deactivate the security system results in the users being trapped in Sector Five and having to wait on someone else to reset the maze from the arena. They do have about a minute or so to escape before this happens though. After recreating Sector Five, Jeremie removes this system, allowing free access to the Sector. After the security system is shut down, a pathway out of the maze opens up. This leads to a multi-directional elevator. It only stops at one point, so a carefully-timed jump is needed to board it. The elevator moves on tracks around the outer surface of the sphere. It will eventually pause to allow its passenger(s) to disembark. It always pauses at the same spot; another platform that leads to the outer surface of Sector Five. On the surface is a special interface that allows full access to the supercomputer, Lyoko, and X.A.N.A.'s data. While the interface is being used, the user controls in the lab are locked out. Leaving the Sector can be achieved 1 of 2 ways: the users can either head back to arena and take the Transport Orb or they can head to the surface and wait for Jeremie to open one of the data streams. The 1st option allows the user(s) to be dropped off anywhere in Lyoko. The 2nd allows them to exit through an exit tower in the sector that corresponds to the data stream they use. Since the towers are destroyed in Season 4, the gang ends up outside of a giant hole outside of Sector Five. Within this Sector are unique monsters that call it home. The first of these are the Creepers. These monsters never leave Sector Five. They aren't very tough, but possesses powerful lasers and can scale the walls of the sector as if they were walking upright. Another are the Mantas. They usually hatch from the outside surface of the Sector to prevent intruders from leaving, but have traveled to other Sectors on occasion. The last is the Scyphozoa. Unlike the other monsters, the Scyphozoa is nearly (if not completely) invincible. To date, it has only been destroyed once. There seems to be only one throughout the show. This monster's main purpose is to steal memories, usually Aelita's. It first appeared in Sector Five, but now travels wherever it is needed. No other monsters appear in this Sector, likely due to its unique layout and purpose. Sector Five is the only Sector which can actually devirtualize the heroes without the help of monsters. Various traps exist in this region that can remove a hero in 1 or 2 hits. One such set of traps are the walls and ceiling of Sector Five, which can easily be moved into positions that will flatten the heroes. Pieces of the ceiling can also be shaken loose, producing the same, albeit less-controlled, effect. As one would expect, getting flattened automatically devirtualizes them. Odd has been the victim of this trap the most; he compares the experience to being run over by a steamroller. Another less-common trap are security lasers. These have only appeared in "Exploration" and when Yumi lost 90 life points of damage in a single hit. This Sector is not connected to the regular materialization program, which means that if the characters lose their life points here, they will not automatically return to Earth unless the proper program is run. In "Exploration," Aelita was forced to sort through the data contained within the Sector in order to find the proper materialization program. This Sector was the first Sector to exist. As described by Franz Hopper, the original Project Carthage seems to be represented by this Sector, even though the project existed before the Supercomputer did. Its purpose was to disrupt enemy communications. For a reason that has yet to be revealed, Hopper sought the destruction of this place. To that end, he designed the supercomputer, Lyoko, and X.A.N.A. to destroy it. He never went through with this plan, though. Instead, he reworked the rest of Lyoko to serve as a sanctuary for him and Aelita. When they were finally forced to travel there, X.A.N.A. rebelled. It isn't clear why he did so, but it is clear that X.A.N.A. took control of the Sector instead of destroying it as Hopper had intended. Within the heart of Sector Five lies Lyoko's core, the entity that holds all of the source codes and vital programs which maintains the virtual world. Should it be Core of lyoko The very Heart/Core of Lyoko itself, which maintains the entire virtual world. destroyed, Lyoko and anyone on it would go with it. The core is suspended near the top of Sector Five's inner chamber by three conduits. The core itself is a miniature version of Lyoko. Surrounding the core are two transparent cubes, both of which act as shields. A large amount of sustained laser fire is required to break through them. Since these shields regenerate with each failed attempt to destroy the core, destroying it takes a long time. The core is only accessible through a passage on the bottom of Sector Five, and the passage is protected by a door that rapidly alternates between open and closed. A key similar to the one that shuts off the timer is present just past the door, and produces a staircase into the actual room. The dock for the virtual ship Skidbladnir is later created in a similar location, and even has an elevator to access it. This elevator, however, stops at several points for easy access. In addition, the dock is located near the top of the huge glowing white orb. As of X.A.N.A's second return the moutain,desert,ice and forsert sectors also return. virtual limbo Seen only twice (once in Frontier and again in Jeremie's dream in Code: Earth), the virtual limbo exists as a null space between Lyoko and the real world. It exists within the Supercomputer's memory, which Aelita is linked to. Jeremie was accidentally trapped here when he 1st attempted to go to Lyoko. The scanner memory had been cut off before the process had completed, trapping him in the limbo. Upon his arrival, Jeremie was able to speak to Aelita through her link to the Supercomputer's memory. Through the link, Jeremie was able to tell the others how to free him. After traveling to all 4 regions and collecting the scanner memory from all 4 passage towers in Season 1, Aelita was able to travel into the limbo and free him. During that time, their minds were connected, which allowed them to sense the other's very thoughts, emotions and feelings. digital sea The Digital Sea is data floating about the network that looks and moves like water, hence the name. It lines every Sector in Lyoko, with the exception of Sector Five, which is lined with an equivalent data barrier. Falling into the sea causes permanent devirtualization, reducing a person to data that is pulled through the network at random. Monsters on Lyoko are destroyed when they impact the sea, producing a large column of energy. Jeremie can track down those people who are lost and use his materialization program to recover them, but he still doesn't recommend falling in since finding them is a difficult task. Yumi is the one of those that has ever fallen in (in Cruel Dilemma), and she was recovered shortly after, though only barely and Jeremie was only able to save her because Odd had inadvertently entered the proper code earlier (by dropping candy on it), creating a one-time materialization program. Aelita has fallen into the Digital sea once (in Distant Memory). However, she was saved by Franz Hopper, who manifested himself as a glowing ball of pure energy. In Season 4, X.A.N.A. William could come and go through the sea as needed. Later, Jeremie decides that the best way to find X.A.N.A. is to search the Digital Sea. To that end, he creates a specialized vehicle dubbed Skidbladnir (after the Norse ship of legend) to explore it. The Digital Sea resembles a large upside-down city, the "buildings" presumed to be networked databases by Aelita. Various network "hubs" are anchored to the city by glowing blue tubes, allowing for near-instantaneous travel across large distances in the network. X.A.N.A. even has monsters inside the Digital Sea, such as the Kongres. Also floating within the sea are specially-designed "Replikas" of Lyoko, created by X.A.N.A. from the data he had stolen from Aelita (Presumably in The Key). Each Replika consists of a single Lyoko sector, and is powered by its own Supercomputer in the real world. Jeremie's plan throughout most of Season 4 is to find a way to destroy the X.A.N.A.-built Supercomputers by creating a method of materializing the group's Lyoko powers into the real world. In "Rock Bottom?", it is stated by Aelita that Lyoko is constantly changing its position on the Network, meaning either different parts of the Digital Sea flow into it at different times as it drifts across the Internet, or that Lyoko isn't actually housed in the Supercomputer at all, but is instead run as a sort of server on the Internet managed by the Supercomputer.

Overview

Overview X.A.N.A. virtualizes monsters to use as minions inside of the virtual world. In place of avatars, they are made to interact with Lyoko's sectors, and mostly uses them to fight the Lyoko Warriors and enemies in the virtual world, guard its activated Towers, and attack targets that it wants deactivated or destroyed. When the goal has been lost or fulfilled, X.A.N.A. either makes them retreat or devirtualize them at will, proving that all of its monsters are merely tools to do its bidding. Virtualization Monsters are created from a basic template program, with all their characteristics, allowing X.A.N.A. to create many monsters, all almost identical. This would correspond to the program created by Jeremie to virtualize vehicles. In some episodes, such as Marabounta, X.A.N.A. virtualizes creatures directly in the field as Jeremie does with the Lyoko Warriors. X.A.N.A.'s monsters take up resources on whichever supercomputer holding the virtual world they fight on. It is capable of sending hordes as seen in The Chips Are Down, but continues to virtualize a few at a time to save machine resources. This is also demonstrated with the Kolossus, which can only be created using the combined power of multiple Replikas around the world network. When monsters fall into the Digital Sea, they are deleted. The destruction of their virtual envelope corresponds to their complete disappearance within the virtual world. Most of them have relatively simple artificial intelligence. monster p.o.v Most monsters have the ability to aim their laser, though they do not seem to do so often. This is shown from the monster's point of view, which is dominated by a trisected, white circle. When targeting something, an upside-down, red triangle follows what they intend to shoot. When it locks on, the red triangle centers within the circle and three red lines connect each vertex of the triangle to the circle. Only a few monsters have directly demonstrated this targeting system, but it is safe to assume that others utilize the same system. powers and Abilities X.A.N.A. equips the monsters accordingly with distinguished weapons and abilities that make each of them a force to be reckoned with in their own right. The primary means of attack they all have in common is their lasers. Every single variant of X.A.N.A.'s monsters are equipped with a pulse cannon capable of blasting amplified red energy bolts located anywhere on their bodies. These lasers generally manifest as narrow light beams as the standard contingent for any monster's firepower. However, depending on the monster, they can manifest in other forms, such as the flat vertical circular sawblade of the megatank or the fire rings of a blok. With every monster, the lasers generally and primarily deliver varying levels of concussive force while on rare occasions, they can simply be used for launching X.A.N.A.'s programs in a more direct manner. One example would be Temporary Insanity where X.A.N.A. used the laser stream fired from the combined forces of two flying mantas to infect Odd and Ulrich with a virus that brainwashed them into inverting their perceptions of both Earth and Lyoko.

They usually attack in large swarms. They are much faster than Bloks, and are fairly hard to hit because of their small stature. Sometimes they attack from surprise. Hornets: These are the first monsters that are capable of flight, and are one of the few to have more than one attack. They can fire rapid-fire lasers from their stingers and spray poisonous acid from their heads. Cutting off their wings makes them completely immobile. Bloks: They are one of X.A.N.A.'s most used monsters. Bloks are cube-shaped turrets with six crab-like legs and have three different attacks: standard laser, fire ring, and freeze ray (which can immobilize its target in ice for exactly three minutes if it doesn't cost the target the remainder of their lifepoints as is has done with Ulrich on multiple occasions). However, with an eye on each side of their 'heads' (four in all), their major weakness is that hitting any eye can destroy them and turning them upside down makes them completely immobile. When they are stacked on top of each other like a wall, they shoot an absolutely devastating grand laser. Krabs: They are arguably the tallest of monsters, the most versatile, and generally found in groups of two or three. They can use their legs to stab their enemies, and fire strong lasers from their eyes. In The Chips Are Down and Wreck Room, they demonstrated the ability to project pulse beams from underneath them. This is the only monster that can be destroyed by cutting off its legs. Megatanks: These are one of X.A.N.A.'s most powerful monsters. They are huge armored spheres with indestructible armored outer-casing. They attack with a powerful elliptical laser that can run straight in all vertical directions. To do this attack, it must expose its support ring the laser is fired out of where the Eye is under its armor, making it vulnerable in that moment. Tarantulas: They were first introduced in New Order, where they were depicted as X.A.N.A.'s deadliest monsters due to having more life points than the others and their lasers doing twice as much damage. They are excellent shooters and are very durable. They can fire ray beams from the tips of their front legs that take twenty life-points per impact. As of Evolution, however, they now fire ray beams from their heads. digital sea monsters Kongres: Found only in the Digital Sea. They have the appearance of giant piranha eel monsters. They are the most common monsters seen in the Digital Sea and have only one laser weapon, which is fired from their eyes. Sharks: Found only in the Digital Sea. Shark-like creatures that attack by shooting torpedoes from their mouths. Kalamar: Found only in the Digital Sea. A special monster created to destroy the Skidbladnir. It attacks by latching onto its target and drilling into it. Unique Monsters Scyphozoa: One of X.A.N.A.'s most valuable tools. It has the appearance of a giant jellyfish and is very difficult to destroy. It has the ability to drain the knowledge, DNA, and life force from a victim with its tentacles. It can also implant X.A.N.A.'s virus, possessing them to do its will. Aelita has been its main target, but it has attacked Yumi once and William twice. Kolossus: X.A.N.A.'s largest and ultimate monster. Created by drawing computing power from all of the hundreds of Replikas that it has established all over the Internet. It has the appearance of a giant lava elemental being, with a giant blade replacing its left hand. Its body is indestructible and one attack from it results in instant devirtualization. The only way to destroy it was to simultaneously attack the Eye of X.A.N.A. on its head and its left sword arm.

X.A.N.A.

X.A.N.A. (or more simply spelled as XANA) is the main antagonist of Code Lyoko. It is an artificially intelligent multi-agent computer program created by Waldo Schaeffer in order to destroy Project Carthage, but its power and intelligence grew thanks to the Supercomputer's Time Reversion, becoming self-aware and hostile towards its creator and humanity itself, betraying him and changing its purpose to world domination. Waldo shut down the Supercomputer after realizing how corrupted his creation became but after a decade, was reactivated and fights the Lyoko Warriors and is determined to survive by escaping the Supercomputer and infecting the global network. Despite succeeding in this and killing its creator, X.A.N.A. finally met its end when Jeremie Belpois activated his own multi-agent system designed to destroy all of XANA's Replikas and succeeding in eliminating the hostile program once and for all. In the non-canon continuity, Code Lyoko Evolution, X.A.N.A. instead returned by infecting another virtual world known as the Cortex and planned to recover the source codes that it hid inside of Aelita Schaeffer, Ulrich Stern, Yumi Ishiyama and Odd Della Robbia, in order to regain control of the network again. However, after deactivating both the Cortex and Lyoko again before X.A.N.A. could regain all of its source code, the Lyoko Warriors succeeding in once again destroying XANA, with no chance of return.

X.A.N.A. apperance

X.A.N.A. is a computer program that has neither physical nor digital form. It keeps an unseen presence inside Lyoko's systems and generates red, pulsating energies that run through the Lyoko Wires when activating a Tower. The specters it manifests into the real world are black, ghostly entities that are extensions of its multi-agent system and are the closest thing it has to a physical existence. XANA X.A.N.A.’s only physical appearance X.A.N.A.'s only real incarnation was in Ghost Channel, masquerading as Jeremie inside a Simulation Bubble meant to imprison Ulrich, Yumi and Odd. It manifested its presence into a monstrous caricature figure of Jeremie, with sharp nails, spiky hair, white glowing eyes and an unnatural aura. In The Key, X.A.N.A. appeared in the form of a massive, whirling specter escaping the Supercomputer above the factory. But the closest thing to a real appearance was in Fight to the Finish, while X.A.N.A. was being destroyed everywhere in the Digital Sea by Jeremie's multi-agent antivirus, the specter that was possessing William was forced out and became a giant entity with its eye symbol on the chest, screaming in agony before it disappears.

William as an ally

After X.A.N.A. returned Willam joined the lyoko warriors as an full fledge ally, only going to lyoko if the gang needs the extra help, to avoid being possessed by X.A.N.A. again.
