History Characters / CodeLyokoLyokoWarriorsFamilies

* 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. [[note]]Though seeing as Yumi's family are likely immigrants at the start of Season 1 that fully settled in France, and the way the judicial system works in France meant that Hiroki was forcibly held back a year and was likely in a type of Summer Camp that explains his absence.[[/note]]

* StatusQuoIsGod: Yumi's parents sometimes get into disagreements, but in the end, everything turns out fine; and when Takeho loses his job in "The Chips are Down", he finds a new one by the end of the episode.

[[caption-width-right:200:[[BigGood The man by whom everything started.]]]]
'''Franz Hopper''' / '''Waldo Schaeffer'''

->''"Project Carthage was military program used to block enemy communication. [...] So I built the Supercomputer, created Lyoko, and last of all XANA, to destroy Carthage."''

->Voiced by: Arnaud Léonard (French), Paul Bandey (English, second season), Alan Wenger (English, third and fourth seasons), Víctor Delgado (Latin American Spanish), Pablo Sevilla (European Spanish)

Aelita's father, the creator of the Supercomputer, Lyoko and XANA. Also a former Science teacher at Kadic Academy.

* AmbiguouslyEvil: Throughout Season 2, when the Lyoko Warriors were researching his life, it became increasingly unclear as to whether or not he is a good guy or an insane madman, with Ulrich at one point suggesting that Hopper is, in a way, a second enemy to deal with. His design for a neuronal headset nearly kills Jérémie (which is why Ulrich brought him as an enemy), Aelita's flashbacks of him are extremely ominous in presentation (even his most heartwarming moments picture him as a rather distant father), and the Polymorphic Specter of him has his personality so down pat that it can deceive a viewer (nobody honestly doubted that the clone was the real deal). Not to mention how his sanity did in fact, [[SanitySlippage plummet]] during his research concerning Lyoko. It isn't until Aelita's memories are restored in the Season 2 finale that Hopper is confirmed to be on the side of the Lyoko Warriors, and he is firmly seen as the BigGood from that point onward.
* AmbiguousSituation: Basically everything about him. We get almost no info about his backstory, alignement, goals, other than various implications in several directions; the only more or less unambiguous thing by the end of the series is that he helped Aelita and the Lyoko Warriors and eventually did a [[spoiler:HeroicSacrifice]] for their sake.
* BadassBookworm: He rarely manifest in person, but when he does, it almost always result in him doing something awesome to help the Lyoko Warriors. ''[[BigBad XANA]]'' considered him enough of a threat to ''miss a chance to destroy the Supercomputer and Lyoko Warriors for good'' if that meant not being able to deal with him.
* BallOfLightTransformation: Unlike other, rather than taking the form of a humanoid DigitalAvatar, Franz Hopper is permanently virtualized on Lyoko under the shape of a large, brilliant ball of light. In a flashback during Episode 57, his form consisted of a cluster of smaller balls of light.
* BigGood: Everything the heroes have to fight against XANA is thanks to Dr. Hopper. He occasionally helps more directly if the situation calls for it.
* ColorCodedCharacters: The towers and monsters under his control are marked by a white aura. His avatar is also marked with white on the Supercomputer when it appears.
* ComicBookFantasyCasting: Appearance-wise, he's Creator/PhilipKDick with added opaque glasses for extra mystery. The creators of the show are fans of him, and also used his surname for "Kadic".
* CrazyPrepared: He locked his journals behind such high-encrypted coding Jérémie predicts it'd take a year to break it, then hid them in a random locker with the key being in a toy doll, which itself was hidden behind a compartment in a wall in a house in the woods. Exaggerated in the novels, wherein among other things, he: manually broke apart and hid [[SelfDestructButton Code DOWN]], bricked up an entire part of the Hermitage to hide ''another'' diary, wrote notes in invisible ink, and [[spoiler:downloaded all his work into Aelita's brain just so she could recreate it if she had to enter Code DOWN]]. The man's ''modus operandi'' was basically predicting and preparing for anything that could possibly go wrong; even XANA turning on him was something he figured might happen, he just had no choice but to flee to Lyoko.
* DemonicPossession: {{Downplayed}}, as while he is certainly no villain, he still does possesses Sissi in order to send a message to the Lyoko-warriors.
* TheGhost: A subversion. While he does technically have an onscreen appearance as his light ball avatar, there are no scenes of him as a human (or just lines of dialogue) that aren't part of a flashback or an imitation by XANA. Given that the mentioned avatar is silent and without any traits, it can be truthfully said that the viewer never gets to see Hopper actually interact with the main cast.
* HeroicSacrifice: [[spoiler:Allows himself to be killed by Mantas while he diverts enough power to the Supercomputer to launch the Anti-XANA Program.]]
* KnightOfCerebus: Make no mistake, he's most certainly the BigGood, but episodes that directly involve him (in particular, his past concerning Project Carthage and TheMenInBlack) tend to delve into darker plot lines than normal. It's worth noting that when dealing with him, XANA becomes ''far'' more driven and dangerous than he usually is.
* TheMentor: He serves this function to Jérémie, helping him to refine his programming and giving him data and better weapons with which to fight XANA.
* MysteriousPast: The specific details of his work concerning Project Carthage is never revealed, even when the show ends.
* NonActionGuy: {{Downplayed|Trope}}. His virtual form is not capable of direct combat, much like Aelita in the first two seasons and he's absent for most of the series. However, the data he gives to the Lyoko Warriors is critical in enabling them to continue fighting XANA, [[spoiler:and in the end, his HeroicSacrifice and compiling of the anti-XANA program effectively gives him more credit in defeating XANA]].
* OpaqueNerdGlasses: In life, he sported a pair of these.
* PapaWolf: Many of his actions are motivated to protect his daughter. Unfortunately for him, XANA knows it, and [[BatmanGambit exploits it throughout Season 4]], using Aelita as bait to draw Hopper out of the Digital Sea in order to kill him. He's willing to take blow after blow as long as he can then get Aelita to a safe location.
* PhlebotinumRebel: Franz Hopper created XANA to destroy "Project Carthage", which he was previously working on. Whether or not he succeeded in doing so is unknown.
* TheProfessor: In a roundabout way, thanks to his diaries.
* ProperlyParanoid: He suspected agents were following him while he was working on the Supercomputer. He was right.
* RealNameAsAnAlias: [[spoiler:Waldo Schaefer]], a.k.a. Franz Hopper, changed his moniker for his middle name and the maiden name of his wife.
* 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".
* StayingAlive: In the season two and four finales, [[spoiler:he sacrifices himself for Aelita. [[KilledOffForReal The Season 4 sacrifice seems definitive.]]]]
* SuperpowerLottery: Like Aelita and XANA-William, he has the Annex Program. He helped and saved the Lyoko Warriors more often than not when using it, possessing Sissi to communicate with them or possessing Mantas to save the Lyoko Warriors. See Aelita's SuperpowerLottery for more information on the Annex Program.
* TheStoic: He has exactly two facial expressions: open-mouthed and closed-mouthed. It helps to present him as a deeply reserved man.
* TranshumanAliens: Hopper is permanently virtualized into Lyoko, and his avatar is a brilliant ball of light, rather than a humanoid like the other Lyoko Warriors.
* MadScientist: He built the Supercomputer, Lyoko and XANA on his own, and lost his marbles due to the strain of his experiments.
* VirtualGhost: Franz was never able to take on a corporeal form on Lyoko, only able to manifest in the form of a cluster of light orbs (Season 3) and a bright ball of energy (Season 4).
* TheVoiceless: While his voice ''is'' heard on screen, it's always either in a flashback, a recording, or a XANA trick. Hopper himself is never heard to speak, as his present-day light ball form lacks the ability to do so.

[[folder:Mr. and Mrs. Ishiyama]]
'''Takeho and Akiko Ishiyama'''

->Takeho voiced by: Mathieu Moreau (French), David Gasman (English), Masaru Uekura (Japanese)\\
Akiko voiced by: Nathalie Stas (French), Jodi Forrest (English)

Yumi's parents.

* BigEater: Takeho is seen twice in Season One wolfing down bowls of noodles in one go.
* GoodParents: They worry about their children, but at some points, this becomes a hindrance to the group due to said concern.
* ObliquelyObfuscatedOccupation: It's never made clear what exactly Takeho's job is.
* OneHeadTaller: Akiko is noticeably taller than her husband, and it seems that Yumi took after her in that regard.
* ParentsAsPeople: Embody this the most out of the parents of the Lyoko Warriors. Being foreigners from another country seems to have put legitimate stress on them at times, with them needing to spend time apart during a Season 1 episode, and Takeo's job-status being critical during a later Season 2 episode. They're also the most observant of Yumi's suspicious behavior owing to her not being a boarder, but considering that their daughter is fighting, as Odd puts it, a demonic ArtificialIntelligence, they're quite right to be worried. Regardless of their issues at times, they love their children no matter what.
* PinkGirlBlueBoy: Inverted in season 4, where Takeho wears a pink shirt and Akiko a light blue one.
* PlotMandatedFriendshipFailure: A marriage version of the trope is at play in "Laughing Fit": Yumi's parents are angry at each other for reasons not completely explained, but they make up by the end of the episode.
* StatusQuoIsGod: Yumi's parents sometimes get into disagreements, but in the end, everything turns out fine; and when Takeho loses his job in "The Chips are Down", he finds a new one by the end of the episode.

[[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, but also shows some useful skills. 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: Yumi seems to think so, and indeed, Hiroki pretty much exists to be annoying for most of the series. There are some signs of him growing out of it during season 4 in regards to his crush on Milly causing him to stammer and become more nervous, but his overall attitude remains the same.
* EveryoneKnowsMorse: He does have an excuse for this, though; he and Yumi learned it to talk in secret at the table.
* HiddenDepths: He demonstrates a surprising ability with picking locks in "Hot Shower".
* HopelessSuitor: To Milly.
* OOCIsSeriousBusiness: There are two times when he won't behave like an obnoxious brat: When XANA's attack at the time seems on the verge of success, and when his crush on Milly pops up.
* 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:Mr. and Mrs. Stern]]
'''Walter and Mrs. Stern'''

Ulrich's parents.
----

* KnightOfCerebus: Make no mistake, he's most certainly the BigGood, but episodes that directly involve him (In particular, his past concerning Project Carthage and TheMenInBlack) tend to delve into darker plot lines than normal. It's worth noting that when dealing with him, XANA becomes ''far'' more driven and dangerous than he usually is.

* NonActionGuy: [[DownplayedTrope Downplayed]]. His virtual form is not capable of direct combat, much like Aelita in the first two seasons and he's absent for most of the series. However, the data he gives to the Lyoko Warriors is critical in enabling them to continue fighting XANA, [[spoiler:and in the end, his HeroicSacrifice and compiling of the anti-XANA program effectively gives him more credit in defeating XANA]].

* AbusiveParents: As mentioned above in Ulrich's profile, Walter is constantly berating his son, only seeming to care about his grades, and not caring about the reason why they are so low by the time of seasons 3 and 4. He also immediately dislikes his son's friends despite not knowing them (As an example, he considers ''Jérémie'', known as Kadic's resident genius by staff and students alike, a good-for-nothing), and rarely contacts Ulrich. Mrs. Stern isn't much better, being an enabler that just sits by and watches her husband berate Ulrich.

* NamedByTheAdaptation: Mr. Stern is named Walter in Code Lyoko Chronicles. Still nothing regarding his wife’s name.

* GoodParents: They're very accomodating to Jérémie, and very understanding of him.

* EducationMama: [[InvokedTrope/Invoked]]; Ulrich's terrible grades is a major contributing factor to his strained relationship with his father.

* CrazyPrepared: He locked his journals behind such high-encrypted coding Jérémie predicts it'd take a year to break it, then hid them in a random locker with the key being in a toy doll, which itself was hidden behind a compartment in a wall in a house in the woods. Taken UpToEleven in the novels, wherein among other things, he: manually broke apart and hid [[SelfDestructButton Code DOWN]], bricked up an entire part of the Hermitage to hide ''another'' diary, wrote notes in invisible ink, and [[spoiler:downloaded all his work into Aelita's brain just so she could recreate it if she had to enter Code DOWN]]. The man's ''modus operandi'' was basically predicting and preparing for anything that could possibly go wrong; even XANA turning on him was something he figured might happen, he just had no choice but to flee to Lyoko.

* BigGood: Everything the heroes have to fight against XANA is thanks to Dr. Hopper. And he occasionally helps more directly if the situation calls for it.

* TheVoiceless: While his voice ''is'' heard on screen, it's always either in a flashback, a recording, or a XANA trick. Hopper himself (in his present-day light ball form) is never heard to speak.

* YouGottaHaveBlueHair: Green in Mrs. Dunbar's case.

* OOCIsSeriousBusiness: There are two times when he won't behave like an obnoxious brat: When XANA's attack at the time seems on the verge of success, and when his crush on Milly pops up.

[[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.
