History Characters / CodeLyoko

* ZettaiRyouiki: Only in the first episode; knee-high stripped socks and a miniskirt are part of the clothes she wears for the school dance.

* IHaveManyNames: She only has one real name, but has to rely on various fake names in the series. Her current alias is Aelita Stones.

* AwesomeButImpractical: His Laser Arrow is the team's primary ranged attack, but unlike his companions he has a limited ammo supply and is pretty much helpless when he's out of ammo. Jeremie can refill him, but it takes time.

* BattleCouple: With Ulrich. Even though they aren't actually dating, it is commented, primarily in season 4, that she and Ulrich fight very well together. During a mission and Jeremie asks who's to be sent in, Aelita suggests them specifically because of how well they fight side by side.

* SpeedEchoes: Possessed humans occassionally display this when moving.

* BossBanter: Usually avoided by the spectres as they fight the heroes, with the notable exception of the spectre that impersonated Jérémie in [[Recap/CodeLyokoS3E12 Double Trouble]], which mocks Jérémie (and Odd) as it attacks, giving the impression that it words are coming straight from XANA himself, a manifestation of his hatred of the heroes and Jérémie in particular.

* MachineMonotone: The spectres sometimes speak like this, but usually manage to emote just enough to fool the heroes.
* MarkOfTheBeast: The Eye of XANA acts as this, usually appearing in the spectre's eyes, but also occasionally on the forehead.

* SpotTheImposter: This comes up occasionally when the spectres impersonate the Lyoko Warriors or someone they know. The heroes learn to do this as time goes on, mainly by looking into their eyes to see if they have XANA's HellishPupils or not.

* TraitorShot: If a spectre is pretending to be a Lyoko Warrior or somebody else they know, this is bound to occur.

* OnlyKnownByTheirNickname: She's always refered to by her nickname, Milly.

* IntrepidReporter: She and Milly attempt to be this, always looking for their "scoop", however, no one really seems to take their journalism very seriously.

* GratuitousDiscoSequence: His secret videoclip Paco Disco.

* MeaningfulName: He's a gym teacher named Jim

* WhatMeasureIsANonHuman: The Lyoko Warriors, with the exception of Aelita, are pretty dismissive of him; they don't really care if he gets punished and call him not a real human... ven though Episode 81 shows he's starting to ''gain'' humanity. Aelita calls them on this, since they treated ''her'' like a human when they thought she wasn't.

* SoProudOfYou: Mr. Stern's last words to Ulrich when it seems that he's going to die in "Zero Gravity Zone". Made HarsherInHindsight when we consider the fact that this was the only nice thing he ever did or said in the entire series.

* TheGhost: Jérémie's mother never makes a physical appearence in the show, but dialogue implies that she's still alive and still married to Michel.

* OpenMindedParent: In "Distant Memory", Jérémie's father is receptive to the idea of his 14-year-old son having a girlfriend, even saying how the boy's romance reminds him of his own relationship with Jeremie's mother. Later in the same episode, Jérémie tells Aelita that his parents have no issue with her staying over at his house.

[[folder:Hiroki Ishiyama]]
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/hiroki_9472.png]]
[[caption-width-right:200:The only AnnoyingYoungerSibling so far.]]
'''Hiroki Ishiyama'''

->''"YUUUUMIII, your boyfriend is here!"''

->Voiced by: Guylaine Gibert (French), Barbara Weber-Scaff (English), Gergei Mayén (Latin American Spanish)

[[AnnoyingYoungerSibling Yumi's younger brother]], appearing in Season 2 and joining the 6th grade at Kadic at the start of Season 3. He shows some [[HeroWorshipper hero-worship]] toward Ulrich, and constantly hounds his sister to date the Stern boy and admit her feelings for him. A bit of a crook, he often blackmails Yumi into doing his homework in exchange for not tattling to their parents when she's out saving the world. [[TagalongKid Unwittingly tagging along]] in some of XANA's attacks, he tends to be a dangerous distraction (in "A Bad Turn"), but also shows some useful skills (like picking locks in "Hot Shower"). He never keeps memories of this thanks to the Returns to the Past.
----
* AnnoyingYoungerSibling: His sole role seems to be teasing Yumi about her relationship with Ulrich. To say she finds this annoying would be an understatement.
%%* BrattyHalfPint
* EveryoneKnowsMorse: He does have an excuse for this, though; he and Yumi learned it to talk in secret at the table.
* RememberTheNewGuy: Hiroki is nowhere to be seen in season 1, even though we see the Ishiyama household a few times. Even in "Holiday in the Fog", when the family are going on vacation, Hiroki isn't seen in the car. Yet when he shows up in season 2, no-one draws attention to his sudden appearance.
* ShipperOnDeck: Of his sister and Ulrich, though it's mostly about teasing her.
* TagalongKid: He's completely in the dark regarding Lyoko, but occasionally participates in helping to curb the damage XANA causes in the real world.
* YoungEntrepreneur: In Season 4, he's shown selling Subdigitals tickets. He refuses to give any discounts.
[[/folder]]

----

* BookDumb

* {{Adorkable}}: He is pretty much the archetypal geek, so this is a given. Though this is mostly visible in his relationship with Aelita; he is fairly comfortable with his little group of friends, and [[NoSocialSkills doesn't seem to care about what people think of him outside of them]].

* {{Adorkable}}: Watch any romantic scene between her and Jérémie and try not thinking she is absolutely precious. That being said, come Season 3 and she's ''much'' more confident in herself.

* TheBigGuy: He is physically the strongest Lyoko Warrior [[spoiler: barring William (which is debatable as X.A.N.A. gave him most of his known powers and William's original powers were unseen)]]. When XANA attacks using a Specter-possessed person or similar vessel, he is usually the one who fights it.

* LoveAtFirstSight: Towards Aelita. Ulrich even comments that he thinks the reason he desired to materialize her in "X.A.N.A Awakens" was because of this.

** William defeated his entire xanafied class with ease in "Lyoko Minus One", notably knocking out three of them in one kick. In "A Lack of Goodwill", X.A.N.A.-William manhandled Jérémie and took down Tamiya with no issue whatsoever. This case is {{Justified}}, since as a xanafied person, he's superhuman.

* BoobsOfSteel: A RareMaleExample. William's bust is bigger than even Aelita's or Yumi's, and for a beginner, he's very good. Under X.A.N.A.'s control, he has no problem wiping out the entire team by himself. {{Averted}} with his Season 4 Avatar, however, as his bust is smaller.

** Both times where [[HydePlaysJekyll he pretended to be freed from X.A.N.A.'s control]] nearly ended badly for the Lyoko-warriors, with Odd only managing to save the day at the last moment.
** In "The Lake", he waits for Aelita ''inside the activated tower''. When Yumi ends up inside instead, X.A.N.A.-William kicks her out of it and proceeds to [[CurbStompBattle curb-stomps her]]. Only [[FightingFromTheInside the good William]] and [[BigDamnHeroes Aelita]]'s respectives interventions prevent X.A.N.A. from completely winning.

** AttackOfTheFiftyFootWhatever: The Kolossus is a giant RockMonster bigger than anything else on Lyoko and capable of destroying anything in a single hit. [[spoiler:As shown when it one-shots the Skidbladnir at the end of the series.]]

** DefeatEqualsExplosion: They explode upon dying, although the conflagration is unharming to others.

** TheJuggernaut: The Kolossus is huge, powerful and pretty much unstoppable by conventional means. While most monsters are weak enough that other parts of their bodies can be damaged to either immobilize them or be sufficient in destroying them, the Kolossus' body is impervious to damage. Even a program that froze its bottom half while it was half-submerged in a lake barely fazed it. The only way to kill it, which Ulrich figured out in the next to last episode, is to strike the Eyes of XANA on its face and arm simultaneously.

* OneHitKill: Technically everyone can one-shot monsters, but only if they AttackItsWeakPoint. Aelita's energy fields surround a monster and hit it from every angle simultaneously, allowing her to destroy the monsters (or paralyze some of the stronger ones) even on a glancing blow, making her the most powerful member of the team in terms of pure power. Then XANA-William came in the picture and was able to tank several of these. Only a fully-charged energy field can instantly get rid of him.

* AbusiveParents: Ulrich has an emotionally abusive dad who only seems to care about his son for his grades, and, if Ulrich's talk is anything to go by, hasn't talked to him for a year. Not to mention his mother who acts as an enabler by simply sitting by and watching her husband harshly berate their son (even scolding Ulrich when he dares to talk back to him).

* TookALevelInBadass: In season 1, Aelita [[DistressedDamsel required Odd, Ulrich and Yumi as bodyguards]], and her only use is deactivating towers. Out of all 26 episodes of season 1, she only destroys ''one'' monster. By season 4, she's the most capable Lyoko Warrior of all -- not only does she have Energy Fields, which are more powerful than any other Lyoko weapon, she also has wings for flight and an ability that allows her to reshape the very world of Lyoko. It's also worth noting that XANA-possessed Aelita has only ever been defeated once, and even then Aelita had already disposed of Yumi and was only devirtualized when a wayward fan hit her by sheer luck.

* OneHitKill: Her energy fields can either instantly destroy monsters or paralyze them, making her the most powerful member of the team in terms of pure power. Then XANA-William came in the picture and was able to tank several of these. Only a fully-charged energy field can instantly get rid of him.

* OverrideCommand: '''Code: LYOKO'''

* MasterOfAll: By this point, Aelita has an long-ranged one-hit-kill attack, a defense that can block both physical hits and the most powerful XANA monster's attack save for the [[GiantMook Kolossus]], the ability of flying without a vehicle, and the ability to reshape the very environment. If she were more aggressively or tactically minded, she would probably outwork all the other Lyoko warriors in the battlefield with the sole exception of William. It shows when XANA manages to possess her one last time in "Wrong Exposure", where she manhandles Ulrich, coming very close to devirtualizing him.

* TheComicallySerious: While he's not completely devoid of a sense of humour he takes himself very seriously. Too much, in fact, for the kind of eccentric he is.

* DepartmentOfRedundancyDepartment

* TookALevelInKindness: In Season 1, Jim would often angrily give the Lyoko warriors punishments for various reasons. It came to head during the last two episodes of that season; where he spent a considerable amount of time trying to find out what they're up to, which made him antagonistic to them in general, to the point of inadvertently causing Jérémie to fall down a flight of stairs. [[MyGodWhatHaveIDone This subsequently gets a horrified Jim fired]], but Jérémie decides to reveal the truth to Jim, as he was injured and needed Moralès to help. From this point forward, Jim seems to become a lot more lighthearted as a character, even after the ResetButton in the Season 1 finale. It's notable that Season 2 is what picks up on the "I'd rather not talk about it..." RunningGag.

* SanitySlippage: Suffered a heavy case of it during the creation of Lyoko. His abuse of the Return to the Past (He repeated the same day over ''2,500 times'' without rest) made him extremely paranoid, as seen in his diary, as well as having a delusion of grandeur, as he called the Supercomputer his 'Great Project'.

* WhatMeasureIsANonHuman: The Lyoko Warriors, with the exception of Aelita, are pretty dismissive of him; they don't really care if he gets punished and call him not a real human...even though Episode 81 shows he's starting to ''gain'' humanity. Aelita calls them on this, since they treated ''her'' like a human when they thought she wasn't.

* TookALevelInKindness: In Season 1, Jim spent a lot more time trying to find out what the Lyoko warriors were hiding, which made him antagonistic to them in general, to the point of inadvertently causing Jérémie to fall down a flight of stairs. [[MyGodWhatHaveIDone This subsequently gets a horrified Jim fired]], but Jérémie decides to reveal the truth to Jim, as he was injured and needed Moralès to help. From this point forward, Jim seems to become a lot more lighthearted as a character, even after the ResetButton in the Season 1 finale. It's notable that Season 2 is what picks up on the "I'd rather not talk about it..." RunningGag.

* CoolAndUnusualPunishment: When he thinks Odd went back on his word and leaked his [[OldShame old dance movie]] to the other students, he punishes him with compulsary disco lessons!

* OldShame: The Disco Paco dance movie he starred in. Until it starts to become a big hit with the students, at least. As for his other past careers, [[CatchPhrase he'd rather not talk about them]].

* TheComicallySerious: He takes himself very seriously. Too much, in fact, for the kind of eccentric he is.

* LoveAtFirstSight/[[LoveAtFirstPunch Punch]]: He's first checking her out as she passes by him to get a vending drink at school, showing [[LoveAtFirstSight an interest in her at first sight]]. But, he properly meets her as his sparring partner during a martial arts class. He makes a slight jab at her martial arts skills before she gives him a roundhouse kick to the face and pins him down, making him set up a re-match with her later on.

* LoveAtFirstPunch: He first casually checks her out as she passes by him to get a vending drink at school, showing [[LoveAtFirstSight an interest in her at first sight]]. But, he properly meets her as his sparring partner during a martial arts class. He makes a slight jab at her martial arts skills before she gives him a roundhouse kick to the face and pins him down, making him set up a re-match with her later on.

** In regards to Yumi.

* StalkerWithACrush: Tends to lapse into this when Yumi spends time with William, such as when he follows her to the pool in "Marabounta".

* WillTheyOrWontThey: With Yumi. According to the SeriesFinale "Echoes", they will... but it was ''highly'' tentative.

** In one episode, he refuses to take the blame for getting himself and Aelita in detention (For context, Odd wanted Aelita to cover for him in gym class... since he spent the whole night up playing a video game).

** In yet another, he gives an embarrassing photo of Yumi to the school newspaper, and then convinces Ulrich to take the blame, which leads her to be furious with the latter for most of the episode. Later attempts to explain "Ulrich's" decision to give the photo away leave him to accuse Ulrich of trying to get Yumi's attention because he likes her. Remember: Ulrich is taking the blame to protect Odd's reputation for reasons of ''friendship''.

* AnchoredShip: In Season 3, she tells Ulrich that she's not going to be anything more than JustFriends with him while they're fighting on Lyoko, because the mission is too important to complicate with romance.

* CelibateHero: Well, Heroine: Takes this position in Season 3, after deciding that she doesn't want to complicate her working relationship with Ulrich by allowing romance into the equation, and instead resolves to be JustFriends with him until the Lyoko problem is resolved. [[UnresolvedSexualTension It doesn't actually]] [[WillTheyOrWontThey change their situation]] any.

* OneOfTheBoys: She's the only girl in her group of friends (except Aelita, who's a computer program for most of the show). She also avoids traditionally "girly" pasttimes, preferring soccer, track and field, and martial arts.

--->'''Yumi:''' Because I find your second-rate Casanova act sickening! In the beginning it was pretty nice but now I'm ''really'' fed up! So why don't you buzz off and ''leave me alone''?

* MindOverMatter: Her main power is [[PsychicPowers Telekinesis]], moving the landscape of Lyoko or her friends with her mind. She once sends a large rock tumbling toward a herd of Kankrelats, crushing a dozen of them in the process.

* SheFu: She takes a far more graceful and gymnastic approach to fighting enemies than Ulrich, Odd, Aelita and William even although she is not as fast as Odd, as agile as the latter or as powerful as Aelita and William.

%%* BattleCouple: With Yumi.

* CrazyJealousGuy: He doesn't take kindly to the idea of other guys being interested in Yumi. It gets especially bad when William enters the picture. A good chunk of the B-plots in Seasons 2 and 3 are caused by him being this. When Johnny comes to him for advice in season 3 over his PrecociousCrush on Yumi, what does Ulrich do? [[KickTheDog Give him advice that'll embarrass him and irritate Yumi]], even though Johnny's [[HopelessSuitor hardly any competition]] at all. Thankfully, by season 4, he largely [[CharacterDevelopment grows out of this.]] But still carries a scowl when he sees her with other guys.

* IJustWantToBeSpecial: His rationale for not wanting to shut down the supercomputer, as he enjoyed being a hero on Lyoko. Given how his [[AbusiveParents father]] has such a powerful, and detrimental influence on his life, it's hard not to argue that his time in Lyoko was a ''major'' distraction from it and made him feel good about being a genuine hero literally saving the world.
* InterchangeableAsianCultures: It's stated he likes Japanese culture, which is presumably the reason his Lyoko avatar is a samurai. However, the martial art he practices is pencak silat, which is Indonesian. Might be justified in real life, as pencak silat was somewhat of a fad in France and Netherlands around TheNineties and the TurnOfTheMillennium.

* LoveAtFirstPunch: He was first seen checking her out as she passed by him to get a vending drink at school, showing an interest in her already. But, he formerly meets her as his sparring partner during a martial arts class. He makes a slight jab at her martial arts skills before she gives him a roundhouse kick to the face before pinning him down, making him want a re-match later on.

* GreenEyedMonster: Ulrich can be ''especially'' jealous when it comes to Yumi.
* IJustWantToBeSpecial: His rationale for not wanting to shut down the supercomputer, as he enjoyed being a hero on Lyoko. Given how his [[AbusiveParents father]] has such a powerful, and detrimental influence on his life, it's hard not to argue that his time in Lyoko was a ''major'' distraction from it.

* JustFriends: With Yumi. At first, the idea of this leaves him frustrated, but by season 4, he seems to have made peace with it.[[spoiler:But by the end of the show, it's left unclear if their relationship is solved or not as they hint at wanting to re-explore their romance again.]]

** Zigzagged in Season 4. He starts to get overshadowed by Aelita and is usually [[TheWorfEffect worfed]] by William, but even then ''everyone'' stares in awe as he singlehandedly curb-stomps XANA's forces in "Hard Luck". Also, there is the fact that he is the one who [[spoiler:kills the Kolossus]] in the penultimate episode.

* ActionGirl: Is proficient in martial arts in real life, and a very capable fighter on Lyoko.

* DyingCurse: In "Final Round", she is the last Lyoko warrior to be defeated by a brainwashed William. As her virtual body disintegrates, she tells him how much she regrets agreeing with the idea to make him a member of the team.

* FriendlessBackground: In "XANA Awakens," she is friendless until meeting Ulrich.

** She also says this about William, but in this case it is genuine.
* IJustWantToBeNormal: Out of all the team, she is the one to be the least comfortable with the struggle against XANA, as it forces her to routinely lie to her family (something she hates to do), [[DesignatedVictim frequently exposes her to XANA's attacks]] and generally makes her life more complicated. By the end of the series, she is, excluding William, the only one eager to shut down the Supercomputer and move on. This is averted in her diary: back in the end of Season 1, she clearly states that she will miss Lyoko... but given that she didn't know how ''long'' the conflict with XANA would last...
* IKnowKarate: Inverted, as although she never mentions it (nor is seen training like Ulrich), she knows karate and uses it in the prequel to beat Ulrich in a pencak silat spar.
* JustFriends: With Ulrich. [[spoiler:Though the finale hints that the two wil start dating]].

-->'''Yumi:''' I. ''Am. JAPANESE!!''

* WhyDidItHaveToBeSnakes: Comments that the Kankrelats are her most hated enemies, calling them disgusting. Apparently bugs in general creep Yumi out, as she is visibly horrified by XANA's cybernetic spiders in "Bragging Rights".
* WillTheyOrWontThey: She had this with Ulrich for most of the series. They decide to be just friends late into season 1, but William's introduction unearths their old dynamic. In "Echoes", [[spoiler:it's hinted that they might start dating]], but it's still very ambiguous.

** During the episode "Saint Valentine's Day", he gets jealous over Odd (supposedly) giving Aelita a present and acts like it's not allowed, but later tells Ulrich and Yumi that they shouldn't be upset over the other receiving presents from Sissi/William.
** He's angry at Ulrich for utilizing a Return to the Past to help Yumi's family (specifically, to get them the winning lotto ticket when her father loses his job), because it made XANA stronger for selfish reasons. Yet in Episode 38, Jérémie performs ''multiple'' Return to the Pasts to increase his intelligence, making XANA ''much'' stronger for even ''more'' selfish reasons.

* TheInsomniac: Frequently spends entire night working on programs to materialize Aelita or improve the Lyoko Warriors' equipment. In one episode, Aelita finds out he didn't even ''realize'' the night was over. In another, he actually falls asleep on the keyboard and it is noted by Odd from the key marks on his face.
* JerkWithAHeartOfGold: He cares deeply about his friends and saving the world from XANA, but he can also be smug, snappish, and hypocritical. In an inversion of how this trope usually goes, the "jerk" parts [[TookALevelInJerkass becomes more noticeable]] in later seasons, as he grows more obsessive about fighting XANA and less tolerant of "wasting time" with his friends.

* LoveAtFirstSight: Towards Aelita.

* TookALevelInJerkass: He already tends to be overworking and a bit snappish (especially when he thinks people are wasting time or not focused on the fight), but becomes even moreso in Season 4. One example? In "Opening Act", he gets angry when he finds out Aelita wants to audition for the Subdigitals, telling her not to "waste her time" (and in the original French, even says it's stupid to her face), much to her crestfallen hurt.

* AbusiveParents: Ulrich's emotionally abusive dad; he seems to only care about his son for his grades, and, if Ulrich's talk is anything to go by, hasn't talked to him for a year. Not to mention his mother who acts as an enabler by sitting by and watching her husband berate their son.
* AchillesHeel: He has vertigo, which flares up at rather inconvenient times. This is presumably the reason his vehicle is the only one with a wheel, whereas the other two can fly. His fighting style isn't much useful against flying enemies, to boot. He can throw his swords, but it doesn't guarantees that it will always hit, and he's left disarmed to boot.

* BadassNormal: Even in the real world, Ulrich is no slouch with a sword. In the episode "A Bad Turn", he uses a katana dropped by Yumi's father to fight a materialized Krabe, and manages to cut one of its legs off and block several laser bolts, one of which was about to kill Yumi. He also defeated a ''xanafied'' Tamiya in "Music to Soothe the Savage Beast" by using a mirror to send Tamiya’s electric charge back at her.

* TheBigGuy: He is physically the strongest Lyoko Warrior [[spoiler: barring William (which is debatable, knowing that X.A.N.A. gave him most of his known powers and that William's original powers were unseen)]]. When XANA attacks using a Specter-possessed person or similar vessel, he is usually the one who fights it.

* BookDumb: He is far from being actually dumb, but his grades are mentioned to be bad in later episodes, especially season 3 (though it's left ambiguous whether he really is bad at school of if he merely lacks time to review due to the time spent fighting XANA; in at least one episode, he manages to focus on his work for a while and actually gets decent grades). This is the major source of his tense relationship with his father.

* CannotSpitItOut: [[EverybodyCanSeeIt He likes Yumi. A lot.]] But he never manages to articulate that -- even in the face of competition.

* CrazyJealousGuy: He doesn't take kindly to the idea of other guys being interested in Yumi. It gets especially bad when William enters the picture. A good chunk of the B-plots in Seasons 2 and 3 are caused by him being this. When Johnny comes to him for advice in season 3 over his PrecociousCrush on Yumi, what does Ulrich do? [[KickTheDog Give him advice that'll embarrass him and irritate Yumi]], even though Johnny's [[HopelessSuitor hardly any competition]] at all. Thankfully, by season 4, he largely [[CharacterDevelopment grows out of this.]]

* GreenEyedMonster: Ulrich can be especially jealous when it comes to Yumi.

* JustFriends: With Yumi. At first, the idea of this leaves him frustrated, but by season 4, he seems to have made peace with it.[[spoiler:But by the end of the show, it's left unclear if their relationship is solved or not.]]

* LoveAtFirstPunch: He first met Yumi as a sparring partner in a martial arts class.

** Even more so to Sissi, but in this case he doesn't really like her that way to begin with.

* BadassCrew: Even when not on Lyoko, Ulrich and Yumi possess advanced martial art skills, Odd is athletic and relatively good at adapting to situations, William has shown both abilities, Jérémie is able to help as much as the others without even fighting, and Aelita has similar smarts to Jérémie and fights at the same time. It's saying something that they fought against XANA's attacks several times and still survived long enough for Aelita to deactivate the towers.

* DangerousForbiddenTechnique: The [[ResetButton Return to the Past]] becomes more or less this for them once they realize its side effects. Using it allows them to instantly reverse any damage XANA might have done with his attacks (save for actual death, but it ''does'' save people who are about to die) and cancel any breach to their secret without having to kill or blackmail witnesses. However, each time they use it gives XANA a permanent boost in power and intelligence. Once they learn about this early in Season 2, they make a strict rule of using it only as a last resort, to the point Ulrich nearly gets fired from the group when he tries to use it for a personal reason. [[spoiler:That being said, this only applied when XANA was still confined to Lyoko. Once he's in the network during the second half of the series and thus, no longer connected to the supercomputer, the Return to the Past becomes safe to use.]]

* EnsembleCast: The five main characters [[spoiler:(and later on, six)]] all get their share of focus and not one of them can be said to be ''the'' main character, though Aelita is the most central to the MythArc.

* LimitedSocialCircle: The heroes are rarely shown socializing with people outside their group, although this is [[JustifiedTrope Justified]] as most of the group, sans Odd, are more introverted in personality, as well as the stress and time commitment of fighting XANA bringing them closer together while isolating them from their peers.

* RecruitTeenagersWithAttitude: Justified; they weren't "recruited" by adults in the first place, Jérémie (who is himself a teenager) just happened to find the Supercomputer and assembles a bunch of comrades of his age for help because he is afraid adults would want to destroy the Supercomputer or shut it down without leaving him the time to find a way to materialize Aelita. Plus, [[AdultsAreUseless the one time they try to break the secret and ask adults for help,]] [[YouHaveToBelieveMe no-one believes them.]] [[spoiler:However, William was indeed recruited.]]

* TeethClenchedTeamwork: At their beginning, they had limited loyalty to each others besides keeping the secret and would often argue or be missing (in "Gravity", Ulrich flat-out refuses to help deal with the current attack so he can take part in a soccer match; and in "Marabounta", he ditches a mission out of embarrassment after receiving mouth-to-mouth from Jim in front of all his classmates), and once XANA started developing into a ManipulativeBastard, proved rather easy to turn on one another. They get better over the course of the series. Except with William, who is flat out rejected when he tries to atone for what he did to them under XANA's control.

* CallingTheOldManOut: In the season 3 finale, his father comes to Kadic to talk to him about his bad grades. At first Ulrich silently submits himself to his criticisms; then his father suggests his friends are the cause of his grades, and Ulrich replies with this trope:

* CannotSpitItOut: He likes Yumi. A lot. But he never manages to articulate that -- even in the face of competition.

* CharacterDevelopment: Starts from being a big JerkWithAHeartOfGold to becoming more grounded and mature than Yumi in Season 4, coming to accept their JustFriends relationship. He's also the one to [[spoiler:mend fences with Sissi in the finale.]] He doesn't ''quite'' get past his rivalry with William however, [[spoiler:criticizing him for his LeeroyJenkins attitude that got him caught by the Scyphozoa despite Odd being ''much'' worse in that department.]]

%%* BattleCouple: With Ulrich.

* CoolBigSis: She's closer in age to the rest of the group than most examples, but she's mature enough to fit the mold pretty well.

* {{BFS}}: As a good guy, this trope is {{Deconstructed}}. His sword has exaggerated proportions, even by Zweihänder standards. [[RealityEnsues However, he has trouble carrying it as a consequence]]. The trope is {{Reconstruction}} upon his xanafication, as XANA gave him improved strength to be able to easily wield it even with one hand.
