'''''Code Lyoko Evolution''''' is the sequel series to ''WesternAnimation/CodeLyoko''. While it could be seen as a continuation of its predecessor, it sports a major difference: instead of the mix of 2D and 3D animation styles that ''Code Lyoko'' was famous for, the 3D has been revamped, and the 2D has been replaced with live-action. It will have at least one season, with 26 episodes. A preview screening took place in Paris on December 5th, 2012, the first episode was streamed on France 4's website on December 19th, 2012, and the first three episodes of the series premiered on France 4 on January 5th, 2013. A US premiere is set for February 2013 on [=MoonScoop=]'s Kabillion channel.

The series starts around six months after the end of ''WesternAnimation/CodeLyoko''. As the former Lyoko Warriors are starting a new year, two successive phenomenons resembling XANA's attacks happen. Though [[ItsProbablyNothing they initially dismiss it as coincidence]], Aelita convinces them to go back to the Factory and reactivates the Supercomputer just to make sure. It quickly turns out that XANA somehow survived by infecting the Lyoko Warriors with his source code right before the destruction of his Replikas, effectively turning them into his {{Soul Jar}}s. To restore himself, he must drain these codes from them. Unable to stop him by shutting down the Supercomputer, the Lyoko Warriors decide to fight him again.

The live-action components were filmed in the Angoulême region of France in July-August 2012, with Kadic scenes filmed at the [[http://fr.structurae.de/files/photos/64/charente/p1220637.jpg Lycée Guez de Balzac]].

An article about all of the information released about ''Code Lyoko Evolution'' thus far can be found on [[http://www.codelyoko.fr/dossiers/dossiercle.cl Codelyoko.fr]] (in French).

'''Note:''' Because this is a sequel to an existing series, only tropes specific to the new series should go here.

----
!!''Code Lyoko Evolution'' provides examples of the following tropes:

* AdaptationalAttractiveness: Miss Hertz and Principal Delmas are both significantly younger than they were in the original show, and Jim is significantly thinner. Franz Hopper's actor, on the other hand, manages to line up with his animated counterpart surprisingly well.
* AdaptationDyeJob: Anthea Hopper, Sissi and Sam are all three portrayed as blonde, despite their original series selves being respectively rose-haired, brunette and black-haired. Averted with Aelita, who has actually rose hair, and zig-zagged with Odd, who has a lighter purple spot in his hair which tends to disappear in some episodes.
* AnimeHair: Odd's conical hairstyle is kept in the 3D animation. In the live action, Odd's hair is gelled, but it is nowhere near its previous height.
* ArtEvolution: For the 3D parts as compared to ''WesternAnimation/CodeLyoko'', though it applies mostly to the Lyoko Warriors and the towers; the Monsters and Lyoko itself remain mostly similar.
%% ArtShift: The shift between 3D CGI and live-action is Medium Blending and not this trope, please don't confuse the two.
* AstonishinglyAppropriateInterruption: In "Friday the 13th", when the group discusses what they'd do with their winnings if they won the lottery.
-->'''Jérémie:''' If I won the jackpot, I'd buy...\\
'''Ulrich:''' Mantas!\\
'''Jérémie:''' [[ComicallyMissingThePoint Certainly not.]]
* TheAtoner: William, who was XANA's [[TheDragon Dragon]] in season 4 of the original series, is now part of the Lyoko Warriors, though not without some initial friction.
* AudienceSurrogate: According to WordOfGod, this was the whole point of adding Laura to the cast. Though this makes her delayed inclusion somewhat odd, considering William ended up returning before her.
* BackFromTheDead: XANA, assuming he didn't just fake his death at the end of the original show.
* BatmanGambit: Episode 12 retroactively makes XANA's first attacks in the pilot into this. There's a tower in the Cortex, but prior to regaining his strength by draining source code from the heroes, XANA couldn't use it for anything more than harmless vandalism. But, by conducting a few harmless attacks to get the Lyoko Warriors to investigate, he gets them to turn the supercomputer back on, allowing him to mount more effective attacks using its towers.
* BigBadDuumvirate: XANA will apparently team up with a new human antagonist named Alan Meyer who will use the Ninjas as minions. [[spoiler:Currently, however, Professor Tyron doesn't even believe XANA is real, allowing XANA to act in his system with impunity.]]
* BigDamnHeroes: William in episode 2.
* BlatantLies: Subverted with Odd:
-->'''Odd:''' I'm not stressed, it's just not working! (''{{beat}}'') Okay, I ''am'' a bit stressed.
* BreakThemByTalking: In episode 17, once Laura slips up and reveals her knowledge of quantum physics, Mr. Graven gets under her skin by deducing the trust issues the others have with her, in addition to offering rewards for betraying them before he inevitably catches them. Aelita comes in before she agrees to anything, but the end of the episode shows she hasn't forgotten the offer.
* BrokenPedestal: Aelita reconsiders the vision she had of her father after learning [[spoiler:he might have created the Supercomputer that generates Cortex, thus allowing XANA to come back]]. She gets better quite quickly, deciding that [[spoiler:Cortex is too different from Lyoko to be from him, too]]. Then comes episode 18, where [[spoiler:her mother is revealed to be working with Tyron]].
* CarFu:
** Odd engages in this with the Megapod in episode 10, after the shifting landscape of the Cortex strands them on top of a building with a small army of Tarantulas bearing down on them.
** In episode 12, XANA returns the favor, using two Megatanks to try to force the Megapod to crash. The Megapod is a lot more maneuverable, though, and Odd tricks the Megatanks into TooFastToStop deaths.
** Yumi does it to a trio of Krabe in episode 18, but it doesn't work out quite as well since they were guarding the bridge to the Cortex core. Yumi knocks them down, but in the process flips the Megapod and nearly falls into the Digital Sea.
* CasualDangerDialog: Like in the previous series, and mostly centered around the boys. William and Odd even discuss their love lives while under fire from XANA's monsters.
* ChuckCunninghamSyndrome:
** Many of ''WesternAnimation/CodeLyoko''[='s=] recurring secondary characters, particularly Hervé, Nicolas, Milly, Tamiya, and Yumi's family, have up and vanished. It's possible that the production staff may have considered casting/re-establishing them to be too much trouble.
** Kiwi is also gone, but his disappearance has a canon explanation. See PutOnABus below.
** Upon being asked whether [[AnnoyingYoungerSibling Hiroki]] would be in ''Evolution'', Mélanie Tran responded, "That's a spoiler!", so his status is unclear.
* CollapsingLair: The Cortex in the final episode, [[spoiler:from Tyron shutting down his own supercomputer to protect it from Jérémie's virus]].
* CombinationAttack: In "Compte à rebours", 121 Bloks stack themselves in a square, combining their attack power and defense. The result is an energy blast that hits like a missile while only one Blok in the group is vulnerable to harm.
* ContinuityNod:
** Jérémie mentions they destroyed all Replikas when Aelita suggests XANA might be on a different virtual world.
** Ulrich performing a self-virtualization.
** Jérémie creating [[spoiler:a virtual clone to replace a missing team member in the real world. Though it was a real rushed job, not even as good as William's Clone]].
* CoolBoat: The ''Skidbladnir'', which returns in the second episode.
* CoolCar: The Megapod
* CreepyChild: The child Spectre in episode 3.
* {{Cyberspace}}: Lyoko, naturally, and the Cortex.
* DangerouslyGenreSavvy: Tyron passed the test that the aliens in ''Film/IndependenceDay'' failed: the Cortex is equipped with a firewall to prevent virus attacks.
* DiggingYourselfDeeper: In episode 7, Odd tries to meet with Samantha in the cafeteria, but is attacked by a Spectre when he gets there. Samantha gets the Spectre to back off, but it held on to Odd long enough that he can no longer talk coherently. The next few lines out of his mouth thus unintentionally come out as insults to Samantha, who storms off.
* DecoyGetaway: Aelita pulls this out... but for once, not on Lyoko! [[spoiler:In episode 21, she disguises Sissi as herself to lure away a polymorphic clone.]]
* DopeSlap: In episode 16, Odd gets slapped twice while driving the Megapod, after Jérémie asked the team to be "his eyes and ears".
-->'''Odd:''' Okay, next to me is William, and behind... I don't know what those two are doing, probably holding hands.\\
(''Yumi stands up and dope-slaps him'')\\
'''Odd:''' Ouch!\\
'''Yumi:''' Jérémie doesn't need anything but the basic essentials!\\
'''Ulrich:''' And nothing else! (''he rises and slaps Odd too'')\\
'''Odd:''' Ah-ouch! You're worse than Krabes...
* DullSurprise: The characters, in both mediums, do not emote as much as one might expect in their situations. Most notably, seeing a tower reactivating itself and Megatanks showing up, Aelita's only reaction is to prepare to fight, without even expressing any surprise. They're better about it in subsequent episodes.
* EliteMooks: The Ninjas. Just one effortlessly beats Ulrich, and they prove an equal match for most of the team in episode 10, which also reveals that [[spoiler:they're real people]].
* EnemyCivilWar: [[spoiler:XANA's monsters fight the Ninjas in episode 16. They're about even, since XANA has more monsters. It turns out that Tyron ignorantly updating his system without knowing about XANA put them at cross-purposes.]]
* EvilCounterpart: [[spoiler:The Ninjas are actually real people sent into the Cortex to defend it.]]
* EyeBeams: The Tarantulas shoot beams from their eye now, instead of using their rapid-fire leg guns. It allows them to sustain fire while moving, something they couldn't do in the original series.
* FacePalm: Odd is still fond of it. Notably [[spoiler:in episode 20, when watching Aelita's clone not even acting close to human]].
* FeetFirstIntroduction: Graven. [[spoiler:Twice, thanks to a Return to the Past.]]
* FlyingSeafoodSpecial: Inverted. The Mantas were always flight-capable. The fact that they've suddenly gained the ability to enter the Digital Sea in episode 18 is treated as quite unusual. They're impressively dangerous there, too, their mines doubling as torpedoes with homing ability.
* GenreSavvy: When XANA starts attacking, Aelita is the first to suspect he is back, while the others dismiss it. To be fair, they had good reason to believe he was dead, and they weren't exactly enthusiastic at the idea of going back.
* GettingCrapPastTheRadar:
** In "Spectromania", when the Spectre child hugs Aelita, Odd snarkily asks her if she is into younger kids now and advises her to get a lawyer. (It's worth noting that Aelita is chronologically in her 20s.)
** Even better is this in Laura's first episode[[note]]To clarify, the word she uses, "bonne", is usually used to denote someone that is good in ''bed'' -- thus her embarrassment.[[/note]]:
--->'''Laura:''' (''to Jérémie'') Well, if you need any help, you can ask me, I'm really ''good''! (''{{beat}}'')... Er... with computers!
** Then there is this about William and Ulrich in "Rivalités":
--->'''Yumi:''' [[WhatTheHellHero What the hell are they playing to]]?\\
'''Odd:''' In my opinion, it's to "Who has the biggest sword"...
** Then this in "Compte à rebours":
--->'''Aelita:''' I hate those code-eater [Spectres]. And let's not talk about their pervert side-effects...\\
'''Ulrich:''' (''chuckling'') If Odd has any pervert side-effect to fear, that would rather be Samantha's, don't you think?
* GroundhogDayLoop: An odd one in "Temporal Paradox". Aelita, Odd, and Ulrich are trapped in a sphere created by Tyron. While they're inside, they're looped through the same few minutes of gym class earlier that day. The rest of time continue to carry on, and each iteration allows Tyron to narrow down where they're operating from. Jérémie eventually realizes what's happening and has Yumi drain the Cortex's power to break the loop.
* HeadbuttingHeroes:
** [[TheAtoner William]] and ''[[PluckyComicRelief Odd]]'', of all people, after [[spoiler:William left Odd trapped in the school's cafeteria as a small revenge for not trusting him. Odd ''doesn't'' take it well when he gets out.]]
** William and Ulrich, unsurprisingly. "Rivalités" is all about them headbutting when they are supposed to team up.
* HesBack:
** A few minutes after the Lyoko Warriors reactivate the Supercomputer, XANA activates a tower and sends Megatanks after Odd and Aelita.
** Also, this is Jérémie's final line in the pilot:
--->'''Jérémie:''' The Lyoko Warriors are back.
* HeroStoleMyBike: Invoked by William in "Rivalité". Just to get on Ulrich's nerves, he has Jérémie give him the Overbike, despite his SuperSmoke power being sufficient to get him there on time.
* HowDoIShotWeb: Yumi and Odd aren't very comfortable with deactivating towers at first. ''Especially'' Odd. He smacks into the wall twice just trying to enter the tower.
* HydraProblem: A trio of Kankrelats show up with this ability in "Jérémie's Blues". Destroying one produces two identical copies.
* HypnoticEyes: The Spectre in "Comment tromper XANA" uses them to transfix the Lyoko Warriors (and mess up Sissi).
* IdiosyncraticWipes: Standard {{Wipe}}s are used, but most display the Lyoko logo twirling around or crossing the screen.
* IdiotBall:
** Odd is holding it when he tries barricading Aelita and Ulrich in episode 15, since the spectres have already demonstrated the ability to go intangible, and they have used this ability in many of their appearances in ''WesternAnimation/CodeLyoko'' (though only late in the series did they start actually using it to phase through walls). So, there is no reason for Odd to believe that his plan would have worked.
** In episode 17, they decide it's a good idea to let Odd drive the ''Skid'' when Ulrich is holding a tracking beacon that lets out an electromagnetic pulse if shaken too much. He proceeds to bang the ''Skid'' against one of the docking clamps on the way out. At no point does it occur to let Yumi drive, when she has done so several times before with greater competence than Odd has thus far demonstrated.
* IKnowMortalKombat: Odd learnt how to drive the Megapod through video games. [[DrivesLikeCrazy And it shows.]]
* IndyEscape: Yumi and William fleeing from Tyron's sphere in "Temporal Paradox". [[spoiler:William doesn't escape, and get caught in the time loop too.]]
* {{Intangibility}}: The Spectre in episode 15 can pass through walls, rendering Odd's attempt to barricade Aelita and Ulrich inside the gym as protection absurdly ineffective. It also used the same trick earlier to hide inside a tree and ambush Odd, [[spoiler:successfully draining his remaining code]].
* InvisibleMonsters: Aelita and Odd get pinned down by an invisible Tarantula in episode 5. Aelita eventually works out where it is and renders it visible so Odd can destroy it.
* ItsProbablyNothing: The Lyoko Warriors' initial reactions to XANA's new attacks. Aelita is GenreSavvy enough to force the others to make sure.
* KeystoneArmy:
** The Blok wall in episode 7. There are 121 Bloks combining their power, but destroying the right one takes out the entire wall.
** The Scyphozoa appears in "Mutiny" with a group of Krabes as backup. All of them die immediately when the Scyphozoa does.
* KillUsBoth: Said by Odd during a classic EvilTwin situation on Lyoko in episode 21. In an inversion of the norm, this is probably the fake one, as XANA was trying to get the heroes off Lyoko to keep the tower running.
* KubrickStare: The default mode for most of the Spectres.
* LargeHam: Let's just say Jim's actor does his best to stay in-character.
* LiveActionAdaptation: The 2D animation of ''Code Lyoko'' has been replaced with live-action sequences.
* LoveMakesYouDumb: Odd is able to trick William into going into a forbidden part of the school (and thus getting 10 hours of detention) just by telling him Yumi is waiting for him there.
* MalevolentArchitecture: The Cortex. Similar to Sector 5, the layout is constantly shifting, such that Jérémie had to design a new vehicle just so they'd make it to the core intact. And if that weren't bad enough, the walls inside the core jut out like spikes to kill the heroes.
* MediumBlending: The alternance from live-action to 3D animation within the show itself, paralleling ''WesternAnimation/CodeLyoko''[='s=] 2D/3D shift. There's also live-action scenes shown within the virtual world, namely when looking up stuff in the Cortex.
* MeleeATrois: Episode 16, "Confusion", features [[spoiler:a battle between XANA's monsters and Tyron's Ninjas, which the Lyoko Warriors are forced to join, striking Krabes, Tarantulas and Ninjas indiscriminately.]]
* MindControlEyes: The spectre in episode 19, once virtualized into Lyoko, paralyzes whoever it touches and causes their eyes to turn black and green like the spectre itself.
* MirrorMatch:
** William fights an evil copy of himself on Lyoko in episode 15, helpfully distinguished by a slight PaletteSwap (and XANA's symbol on the copy's forehead).
** "False Pretenses" has this with both Odd and William against their doubles at the same time, with the added problem of the doubles being identical and neither party being sure which is the real one. Jérémie eventually makes the fakes obvious.
* MomentKiller: A running gag in the pilot, where XANA repeatedly attacks when Ulrich is about to confess his feelings to Yumi. (Or Jim arrives.)
* MonochromePast: The flashback to Aelita with her mother in episode 19 (though not quite enough to disguise the fact that they didn't bother with pink hair for the child actor).
* MutualKill: Odd and a Ninja in episode 16, and again in episode 20.
* MythologyGag:
** In episode 1, when Yumi is in her martial arts outfit, her hair is done up in the same way as it was in her first Lyoko form.
** In episode 5, William steals Yumi's usual saying, "''Sympa l'accueil...''" ([[SarcasmMode "Nice greeting..."]]).
** This exchange from Episode 9:
--->'''Ulrich:''' Did you see Mrs. Hertz? Hasn't she got a new haircut?\\
'''Yumi:''' [[BlatantLies No.]]
* NeedleInAStackOfNeedles: The Blok wall in episode 7 is invulnerable except for an identical-looking master Blok. Jérémie provides Odd with a scanner that is able to spot the right one.
* NiceJobBreakingItHero: As a result of [[spoiler:erasing Laura's memories]] in "Mutiny", Tyron ends up [[spoiler:discovering the gang's identities because Laura kept a card for Tyron's company, then innocently identified Jeremie's friends when Tyron showed their avatars to her]].
* NoEnding: Season 1 fails to resolve much of anything. [[spoiler:Aelita only briefly gets to speak with her mother, the gang's attempt to destroy the Cortex is stifled by Tyron simply shutting it off (with the possibility that he can turn it back on once he figures out how to beat their virus), and the gang meanwhile has shut off their own supercomputer to deny XANA its use.]]
* NotAGame: Aelita has to remind Laura of this in episode 12, after she lightly brags about deducing the nature of XANA's latest attack when Jérémie could not.
* ObfuscatingStupidity: In episode 17, Jérémie manages to downplay his genius convincingly enough that Mr. Graven has no suspicions at all he's one of the kids he's searching for. Unfortunately, Laura isn't so shrewd.
* OffhandBackhand: Yumi to a Blok in the third episode.
* OOCIsSeriousBusiness:
** The Lyoko Warriors are stupefied that Yumi actually feels sorry for William and considers reintegrating him, despite the fact she was the most violent to oppose his return before.
--->'''Odd:''' Who are you and what are you doing in Yumi's body?
** Also, Ulrich is surprised when William [[spoiler:actually tries to get him to reconcile with Yumi in "Soupçons".]]
** Sissi didn't insult Odd after he bumped against her? She must be a Spectre! [[spoiler:Except, no.]]
* OutOfFocus: Despite Sissi being one of the major secondary characters in the previous series, and their offer of friendship to her at the end of the original series, WordOfGod says her role will be downplayed (but not erased) in this series.
* OutsideRide: A Ninja take a ride outside the ''Skidbladnir'' in episode 14, "Intrusion".
* PlayingSick: Another fine tradition of ''Code Lyoko'' that is perpetuated. Notably Odd in episode 20, [[spoiler:before Ms. Hertz find out there's something wrong with Aelita's clone]].
* PutOnABus: Kiwi is no longer present (likely because having him might've been an added difficulty in the live action); it's explained in episode 18 that Odd left him with his sisters.
* ReedRichardsIsUseless: Invoked; after they reactivate Lyoko, Odd points out how it's a waste to not use this virtual world now that XANA is (supposedly) gone and suggests they use it to make a virtual attraction park. The idea is rejected by Jérémie.
* ReformedButRejected: Even after several months, the Lyoko Warriors are still reluctant to allow William to come back; it takes an emergency to have him come back to Lyoko, and even then they decide to think about reintegrating him. Aelita even almost attacks him when first seeing him on Lyoko again, admitting his SuperSmoke still makes her nervous. They finally get over it in the fifth episode.
* RockPaperScissors: Ulrich and Odd in episode 23, to decide who will pilot the ''Skid''.
* SarcasticClapping: Odd does this in "Les Sans-Codes" just after [[CaughtInASnare catching the rest of the team in a net]], to show them that they are vulnerable.
* SeriesContinuityError:
** While all the Lyoko warriors being able to shut off towers is new, their ability to enter them is not, despite them acting like they've never done it before. This might be handwaved as them never entering an ''active'' tower before, but it's still a stretch. In the original series, when Aelita was briefly prevented from entering activated towers, it was implied that it required some additional amount of conscious effort to do so.
** The point of the ''Skidbladnir'' is to protect the Lyoko Warriors from the Digital Sea, as contact would otherwise be fatal. Apparently no-one told the Ninjas that, as one is able to hitch a ride to Lyoko simply by clinging to the outside of the ''Skid''. On the other hand, XANA did manage to protect William from the Digital Sea during his time as a minion, so Tyron and his Ninjas could potentially duplicate that trick.
* ShoutOut:
** As Kadic Academy is an homage to Creator/PhilipKDick, Deckard Enterprises is an homage to the character of Deckard from ''Film/BladeRunner'', based on a story by Dick.
** In episode 1, the controller Odd offers Ulrich is clearly a Gamecube controller.
** At the beginning of episode 13, Jérémie is reading ''ComicBook/TheWalkingDead''.
* SixthRanger: William is now a full on member of the team, for real this time, and Laura will be one eventually.
* SomethingOnlyTheyWouldSay: Constantly in episode 21 to identify each other, as XANA's polymorphic spectres take the appearances of the heroes, both on Lyoko and the real world. When William asks one out of Ulrich, [[VitriolicBestBuds the latter just insult him]], proving his identity.
* SoulJar: XANA has turned ''the Lyoko Warriors'' into his Soul Jars by injecting them with his source code, which he needs to extract from them to restore himself completely. The extraction is done through physical contact with Spectres, which also weakens them. On the plus side, all four can now deactivate towers. [[spoiler:Odd becomes the first victim of a total drain in episode 15, but gets a bit back in 19.]]
* SplitScreen: Used generously, notably during virtualization and for some simultaneous actions on Lyoko and the real world.
* SplitScreenPhoneCall: Common too.
* SpotTheImposter: "False Pretenses" is roughly half this trope, both in the real world and on Lyoko. The ones on Lyoko get their cover blown by Jérémie when he makes them glow, while the one in the real world blows his cover as Ulrich with SomethingTheyWouldNeverSay.
* StatOVision: In episode 7, Odd gains this thanks to Jérémie programming a "cinetic ocular" in order to analyze the Blok wall.
* SuperSmoke:
** Still one of William's abilities on Lyoko, inherited from his BrainwashedAndCrazy period in the parent series, despite him joining back the heroes.
** A spectre virtualized into Lyoko in episode 19 flies around as a dark cloud of binary code.
* TakeMyHand: William does this for Ulrich in the fifth episode when he's about to fall into the Digital Sea.
* TalkingToTheDead: Aelita gets into the habit of talking to her father while on Lyoko, usually by adressing the Lyoko Core.
* ThereAreTwoKindsOfPeopleInTheWorld: William in episode 11. "In life, there are those who talk and those who act." Later played with:
-->'''William:''' When I spoke about action, I didn't expect you to do crazy things!\\
'''Odd:''' You're never happy.
* TimeSkip: Though a very small one, ''Code Lyoko Evolution'' still takes place roughly 5-6 months after the end of ''WesternAnimation/CodeLyoko''.
* TookALevelInJerkass:
** Granted, Aelita never really got a chance to be jealous in the previous series, but ''man'', she is '''cold''' when she gets that way.
** Jérémie had some personality defects in the original, but they're taken UpToEleven here.
** Also, William, due to his spite of not being accepted back in the Lyoko Warriors. He seems to be getting better, though.
* TookALevelInKindness: While he retains all his hamminess, Jim is portrayed in this series as much nicer and less aggressive than his animated version was. He's still generous with detention, however.
* TronLines: A few over the Cortex, and inside the Megapod.
* WeNeedADistraction: Attempted by William to get Yumi to the tower in "False Pretenses". The three Krabes he tried it on saw right through the ruse, and a fourth was waiting to hold William up while the first three chased Yumi down.
* WhamEpisode:
** Episode 18, "Obstination": [[spoiler:Anthea Hopper is working with Professor Tyron.]]
** And then Episode 24, "Paradoxe temporel": Due to [[spoiler: Jérémie erasing Laura's memories via an upgraded [[ResetButton Return to the Past]] in episode 22, "Mutinerie"]], Laura [[spoiler:calls up Tyron to figure out how she got his business cards and ends up giving him Jérémie's identity by telling him the Lyoko Warriors' avatars look like Jérémie's friends]].
* WhatTheHellHero:
** Aelita sort of delivers one to the Lyoko Warriors when they don't take her warning that XANA might be back seriously:
--->'''Aelita:''' XANA might be back and that makes you laugh? A few years ago, you would have rushed without any hesitation!
** Aelita gets this in return when she arbitrarily decides to set off the return to the past and wipe Laura's memories of the factory, ''after'' the group had decided to vote on it. She's totally unapologetic about it, too. To be fair, their rule for adding people to the group is "by unanimous decision". Aelita's actions there were basically her negative vote, but she didn't even give the others a chance one way or another.
** Ulrich and William both get one from the others in "Rivalités" for letting their rivalry get the better of them when they are supposed to team up on Lyoko.
** In "Virus", Laura defends her underhanded method of keeping her memories after a Return to the Past by pointing out they were perfectly willing to use her then get rid of her without giving her a say in it.
** Laura gets this in turn in episode 12, when she brings her father into the lab without discussion or warning. She was trying to convince him not to move her to another school.
** Yumi gets some flak in episode 14 for letting her relationship with Ulrich interfere with the mission, to the point of deliberately getting herself devirtualized mid-battle in an attempt to patch things up.
* WritersCannotDoMath: In the third episode, Jérémie measures the total percentage of XANA's code left in each of the heroes (92, 77, 93, and 90), then comes up with XANA's current total, which is given as 70 (instead of the mathematically-correct 48). In the fifth, the new totals are 88, 68, 79, and 75 (42 less than before), yet XANA has gained a grand total of 5. Even if one were to accept there isn't a direct increase, the two totals aren't even consistent as a ratio. [[spoiler:Then came episode 15, where completely draining Odd of code corresponded to a mere 10 point increase.]]
* YourPrincessIsInAnotherCastle: A minor example used by XANA as a strategy in "Spectromania"; when the Lyoko Warriors successfully deactivate the tower, it turns out he was using the first tower to hide another one that had its own Spectre.
* YouGottaHaveBlueHair:
** Aelita aside, some extras have been spotted with bright orange or blue hair. WordOfGod says this was deliberate in order to make Aelita's pink hair seem less strange in-universe.
** Inverted with Anthea Hopper, who was made blonde despite having pink hair like her daughter in the original series.
