History Characters / CodeLyokoKadicAcademy

* {{Jerkass}}: [[DependingOnTheWriter At her worst]], she's very mean, smug, and condescending to others, especially Milly and Tamiya (Whom she likes to [[TheBully belittle and humiliate]], [[ItAmusedMe often unprovoked]], and Herb and Nicholas (whom she [[WithFriendsLikeThese treats less like friends and more like servants]]). She was mostly this in season 1 and TookALevelInKindness later, becoming more of a...

* EarnYourHappyEnding: [[spoiler:After 3 seasons of snooping around and indirectly helping out the gang during XANA attacks, Sissi finally gets to befriend the Lyoko Warriors and is included in their group of friends, though she's not a full fledged member. Ironically enough it's ''Ulrich'', the boy she has a hard crush on (and the one who initially banned her from being a full fledged Lyoko Warrior) was the one to set things right.]]
* FriendlyEnemies: She and the gang are mostly very civil and casual with each other throughout Season 4. It only stops (temporarily) toward the end when her old suspicions consume her again, PlayedStraight by the sequel series where she's a genuine friend to the gang despite not being a full fledged member.

* HormoneAddledTeenager: She's a little ''too'' amorous for her age, even.
* IJustWantToHaveFriends: As early as Season 1, she admits that her primary reason for fixating so much on the main characters is that she wants to be included in their group of friends.
* InformedAttribute: Stated by Ulrich to be a DudeMagnet in the prequel; however, the number of boys seen actually hitting on her onscreen doesn't exceed three (two of them being [[KidAnova Odd]] and [[AbhorrentAdmirer Herb]], and the third being a one-shot character who forgot about her as soon as he saw Yumi), and minor characters have been shown to be pretty aware of her being a BrainlessBeauty. In fact, Yumi technically gets more attention from boys than she does. Both girls eventually get outdone by Sissi's Icelandic pen pal Brynja who gets the attention of every boy in the school.

* ThenLetMeBeEvil: As revealed in the prequel, [[spoiler: she became more of an AlphaBitch thanks to the gang automatically distrusting her for something that, for all intents and purposes, never actually happened.]]

* DoNotCallMePaul: "It's ''Sissi''! Not ''Elisabeth''!"

* FriendlyEnemies: She and the gang are mostly very civil and casual with each other throughout Season 4. It only stops (temporarily) toward the end when her old suspicions consume her again.

* HeelFaceRevolvingDoor: Owing to DependingOnTheWriter, but there are episodes where she can either be a selfless and very useful ally, and ones where she's either a nuisance, or a legitimately manipulative threat to the Lyoko Warriors.

* InformedAttribute: Stated by Ulrich to be a DudeMagnet in the prequel; however, the number of boys seen actually hitting on her onscreen doesn't exceed three (two of them being [[KidAnova Odd]] and [[AbhorrentAdmirer Herb]], and the third being a one-shot character who forgot about her as soon as he saw Yumi), and minor characters have been shown to be pretty aware of her being a BrainlessBeauty. In fact, Yumi technically gets more attention from boys than she does.

* JerkWithAHeartOfGold: She's a bratty, self-absorbed snob, but she's a decent person deep down who can be incredibly brave and selfless when push comes to shove in a XANA attack (if he hasn't possessed her, of course). And she does genuinely care for Ulrich, even if she has a funny way of showing it.

* LockedOutOfTheLoop: In the prequel two-parter episode where she is informed about Lyoko, she almost immediately tells the school staff about it and the Supercomputer's location, risking having them shut down (though she did only reveal it out of fear for their safety). After her memories of it are erased by Return to the Past, the group decides that she's too much of a blabbermouth to be trusted with knowledge of it.

* MsFanservice: When she's not in a LingerieScene, she's dressed to play this to the hilt.

* BlackDudeDiesFirst: In "Attack Of The Zombies", she's the first character to be zombified by Kiwi.

* TokenMinority: She is black.

* MultiethnicName: Has an Anglo-Saxon first name (if Jim is short for James) and a Spanish surname (though weirdly spelled, as the real life surname is Morales, not Moralés).

'''Elisabeth''' (Elizabeth) '''"Sissi" Delmas'''

* ShipTease: With Odd, particularly in Season 2's "Déjà Vu" and Season 4's "Kadic Bombshell" and "Bad Connection".

* SpellMyNameWithAnS: His surname is officially written as "Moralès", but some dubs spell it by the more regular form "Morales" (the difference being, respectively, "Mo-ra-LES" and "Mo-RA-les").

* CloningBlues: Averted. He's not self-aware enough to care that he's just a replacement doomed to disappear when the true William comes back.

Odd's dog, which he brought secretly in Kadic and now hides inside his room with the help of Ulrich, since pets are forbidden at school. Kiwi tends to not do much besides eating, sleeping and in some occasion wreaking havoc in the room. Odd, however, is devoted to it.

[[folder:Élisabeth "Sissi" Delmas]]

'''Élisabeth''' (Elizabeth) '''"Sissi" Delmas'''

* DemotedToExtra: In Season 3 and 4, especially 3 (she becomes relevant again late into Season 4).

* DoNotCallMePaul: "It's ''Sissi''! Not ''Élisabeth''!"

* InformedAttribute: Stated by Ulrich to be a DudeMagnet in the prequel; however, the number of boys seen actually hitting on her onscreen doesn't exceed three (two of them being [[KidAnova Odd]] and [[AbhorrentAdmirer Hervé]], and the third being a one-shot character who forgot about her as soon as he saw Yumi), and minor characters have been shown to be pretty aware of her being a BrainlessBeauty. In fact, Yumi technically gets more attention from boys than she does.

* OnlyKnownByTheirNickname: Only adults ever call her "Élisabeth", and she hates that. Everybody else calls her "Sissi".

[[folder:Hervé Pichon]]
'''Hervé Pichon'''

* AlwaysSomeoneBetter: Hervé is a good student in general, but [[TheHero Jérémie]] always has better grades than him.
* BrainsAndBrawn: He's the brain to Nicholas' brawn.
* CheatersNeverProsper: In "The Robots". Hervé cheats on the robot competition against Jérémie in order to win, however, proof that he cheated is found on the video record Milly and Tamiya have made, and it's implied that even if a return to the past hasn't been done, he would've been outed as a cheater anyway. Played straight in the same episode after the return to the past, as Jérémie knew what to do in order counter Hervé's attempt at destroying Kiwi II.
* TheDragon: The closest thing Sissi has to one. Nicholas is DumbMuscle, and thus for actual schemes, she kinda has to default to Herv&eacute.

* OddFriendship: With Nicholas, as they seem to have very little in common.

* ThoseTwoGuys: With Nicholas.

[[folder:Nicholas Poliakoff]]
'''Nicholas Poliakoff'''

* AnnoyingLaugh: Nicholas seems to be known by his, with Odd stating in "The Chips Are Down" that he would recognize his laugh anywhere.

* BrainsAndBrawn: The brawn to Hervé's brains, though he isn't seen strongarming too much.

* LiteralMinded: One example of this happens in the final episode where Sissi needs an excuse to be absent from class and tells Nicholas to tell Jim the first excuse that pops into his head. HilarityEnsues when he tells Jim that Sissi ran into some aliens and went crazy.
* OddFriendship: With Hervé, as they seem to have very little in common, yet are ThoseTwoGuys regardless.

* ThoseTwoGuys: With Hervé.

'''Amelia "Milly" Solovieff'''

* BareYourMidriff: She wears a belly-shirt everywhere.

* ThoseTwoGuy: He and Jim sometimes have this dynamic, being Kadic's primary adult authority figures; they can often be seen together discussing the events going on or working together.

* AdaptationalBadass: In the novel continuity, she's confirmed to have military history, once being known as Major Steinback, and was Franz Hopper's primary confidant and ally during his time on the run from the Men in Black, and is the most notable of the adults on the Lyoko Warrior's side during their conflict with the Green Phoenix. The show proper never confirms if any of this history is true; the only confirmed root is that after Franz's escape to Lyoko, she took his place as Kadic's science teacher, with more esoteric guessing being based in her seeming to have a wider intellectual range at times than one might expect from a regular science teacher.

* AdaptationalBadass: He's in on the conspiracy concerning Franz Hopper's disappearance in the novels. Unlike with Miss Hertz, who displays personality traits and knowledge in the show that tracks well with Hopper's own intellect at times which makes the detail potentially plausible for the animated series' backstory, this is more easily confirmed as an invention of that continuity; no indication is ever given in the show that he was aware of Hopper's activities, indeed, "Wrong Exposure" confirms that Delmas was clueless about Aelita's past.

* DependingOnTheWriter: The level of sympathy her character is treated with changes from episode to episode; shown moreso in Seasons 2 and 4 (where she was sympathetic in the majority of her appearances) than 1 and 3 (where she... wasn't, though she did have moments in 1 and Season 3 saw her DemotedToExtra). Her level of intelligence also varies. While in Seasons 1 and 4 she can be very smart, she's mostly shown as stupid in the prequel and seasons 2 and 3.

* JerkWithAHeartOfGold: She's a bratty, self-absorbed snob, but she's a decent person deep down who can be incredibly brave and selfless when push comes to shove in a XANA attack. And she does genuinely care for Ulrich, even if she has a funny way of showing it.
