17''Code Lyoko'' is an {{Animesque}} show that was written and produced in France in English and French for simultaneous release in its home nation as well as the US -- and about 160 other countries.
18
19It follows the adventures of a group of teenage students at a BoardingSchool who discover a supercomputer in the basement of a nearby abandoned factory. The computer has modules that allow people from the real world to "virtualize" into the Cyberspace of Lyoko, where an evil A.I. named XANA is apparently hunting down a pink-haired girl named Aelita. The computer also has the ability to effect a temporal recursion (in LaymansTerms, rewind time) up to 24 hours in the real world. The show's primary aesthetic hook was that scenes in the real world are depicted in 2D animation, while scenes on Lyoko are animated in CGI.
20
21XANA manifests in Lyoko indirectly through a variety of monsters with various attacks and tactics, trying to capture Aelita and repulse her protectors from the real world. XANA also attacks the real world, which at first resembles the results of TheCracker, doing damage through various interfaces, but these attacks slowly gain a supernatural edge, including summoning monsters in the real world, and [[BodySnatcher possession of students and teachers]].
22
23The students often use the [[ResetButton Return to the Past]] function to repair damage and effect a kind of {{Masquerade}} to protect Aelita, however with the knowledge that [[AllDeathsFinal death is permanent -- not even time travel will bring them back]].
24
25The [[FiveManBand five main characters]] (Aelita and her protectors) are occasionally referred to as "The Lyoko Warriors" or [[FanNickname Team Lyoko]]. See the [[Characters/CodeLyoko character sheet]] for individual descriptions.
26
27The episode recaps of all the episodes can be found [[Recap/CodeLyoko here.]]
28
29The entire show is officially available on Website/YouTube in both [[https://www.youtube.com/playlist?list=PLDdlwI0EwS7TpHbfjMCjvm62n9WA-3Z-l English]] and [[https://www.youtube.com/playlist?list=PLG5nW1nH7k18DwYx69mkDOYJ-G1CU7dnk French,]] as well as being added to most regional versions of Creator/{{Netflix}} on 1st October, 2020 (in widescreen, and in better quality).
30
31There is a short (5 minutes long) film made in 2001 by the creators of the show, ''[[https://www.youtube.com/watch?v=bgiNbuFwORw Garage Kids,]]'' that is considered a test {{pilot}} for the series. It introduces the main characters and some future elements of ''Code Lyoko'', though there are differences both visually and plot-wise. ''Code Lyoko'' began broadcast in France in 2003 on France 3 and Canal J, and in the United States in 2004 on Cartoon Network. The TV series ended in 2007 after four seasons and 97 episodes (including a two-parter prequel).
32
33In the summer of 2011, [[UnCancelled a new twenty-six episode series was confirmed to be in production]], titled ''Series/CodeLyokoEvolution'', and it was released in fall the following year. ''Evolution'' is a [[PostscriptSeason continuation of the original show]], with [[LiveActionAdaptation live-action]] replacing the 2D segments. All tropes relating to this series should go on its page.
34
35Between the two TV series, a novel series was produced by Atlantyca Entertainment. The series, originally written in Italian, takes place in a heavily expanded AlternateContinuity which promises to tie up some of the plot threads left hanging by the show. The series is [[KeepCirculatingTheTapes officially]] available in 11 languages, not including English. However, an English fan-translation of the series is available for download [[https://archive.org/details/codelyokochroniclesbook4thearmyofnothing/Code_Lyoko_Chronicles-Book_1-The_Underground_Castle here.]] The series includes the following books:
36* ''The Underground Castle'': March 2009 (Italy), September 2010 (France)
37* ''The City with No Name'': November 2009 (I), March 2011 (F)
38* ''The Return of the Phoenix'': April 2010 (I)
39* ''The Army of Nothing'': November 2010 (I)
40
41A ''Code Lyoko'' stage show was also produced and performed in Spain in March of 2011.

48[[folder:Tropes # to E]]
49* TwoDVisualsThreeDEffects: Some CG are mixed with the real-world animation, notably computer displays or water effects. In a strange inversion of the trope, the real-world CG effects become ''more'' obvious with each passing season (a couple CG door swings in Season 3, for example).
50* AbsurdlySpaciousSewer: Though it should be noted that this particular series ''is'' set in France, so it's not quite as unusual. Also, the tunnel regularly used by the heroes is more of a storm drain than a sewer, since the water flows directly into the river.
51* AchillesHeel: Megatanks are potentially the most powerful of all of XANA's monsters. However, because they're so big and bulky, they have trouble controlling their momentum, and this sometimes leads to them plunging straight into the Digital Sea. In fact, if you get enough running momentum going, you can literally ''push'' them to their doom. Consequently, they're the one kind of monster most frequently taking a dive in the show. Yet they are also seen repeatedly stopping instantly to aim at one of the heroes.
52* ActionGirl: Yumi kicks just as much ass as Odd or Ulrich. Aelita starts out fairly weak, but she later gains an energy field ability that can be used both offensively and defensively, as well as the ability to fly.
53* AdultsAreUseless:
54** On most of the occasions that adults become aware of XANA's actions, they attempt to barricade the heroes for their own safety, often at times in a single room at the school. On the odd occasion they actually do help the kids, the ResetButton abuse result in them forgetting everything after they find out just what the kids were really doing. In fact, adults are often XANA's targets when he decides to possess someone, and one of the side effects of Specter possession is total memory loss for its duration. He generally does this for pragmatic reasons as adults tend to be stronger than your average 12 year old.
55** In the 9th episode, "Satellite", one teacher's class is interrupted by ''every single student's phone ringing at the exact same instant,'' and it's implied that this has happened to the entire boarding school campus. Her reaction (and the reaction of every seen faculty member) is not to investigate what on earth caused such a thing, but to confiscate the cell phones of every single student in school (because they had them on in class), and then ''try to deactivate the signal tower so that nobody can use their phones even if they steal them back.'' Even in a universe where XANA ''isn't'' trying constantly to get people killed, this is an astronomically unsafe thing to do, and could quite plausibly result in one or more students ''dying'' because of an emergency in which they find themselves unable to get help.
56** In the episode "Attack of the Zombies", the entire episode is spent mostly with the students in the cafeteria. When the aptly titled zombies attack the campus, the only adult with the kids (Rosa the lunchlady) spends the entire episode completely unconscious out of pure shock, and contributes nothing to helping save the kids who aren't affected. The Groundskeeper is actually visited by a police officer after they investigate a call saying there are "zombies". The police don't believe it, but have come to make sure regardless nothing is wrong. When the groundskeeper says everything is fine and he hasn't seen anything, they leave. Moments later, he's attacked by a zombie.
57* AerithAndBob: While names like Jérémie, Elisabeth and William are all rather common, other characters have names that look incredibly out of place:
58** Justified in Yumi Ishiyama's case, as her name appropriately references her Japanese heritage.
59** Odd is a Norwegian name, but Della Robia implies he is of Italian descent.
60** Franz and Ulrich's names are of German origin.
61** Aelita's is the most egregious, as her name is a direct reference to a fictional ''Soviet'' character.
62* AffectionateNickname: Odd, Ulrich, and Yumi often call Aelita "Princess", and Jérémie "Einstein".
63* AliceAllusion: A rather [[{{Pun}} odd]] example, but do you think Odd's Lyoko form is a "giant purple cat" just because? Do note the one episode where teleportation in-Lyoko causes cloning... Maybe Mr. Cheshire can do that.
64* AliensInCardiff: AIIsACrapshoot and going all SKYNET... and it's based out of an abandoned factory in the Parisian suburb of Boulogne-Billancourt (or at least a NoCommunitiesWereHarmed version of it).
65* AllDeathsFinal: [[TimeTravel The return to the past]] cannot bring people back from the dead. It's not explained why, but it does help maintain drama.
66* AllThereInTheManual: A lot of the "game" mechanics in Lyoko are rarely if ever explained in the show itself (and are often contradictory there); we only know about them because of supplementary material. And even then, despite figures given about every combatant's weapons and Life Points, everything defaults to the RuleOfDrama. Any shot fired will either [[ATeamFiring miss]] [[ImperialStormtrooperMarksmanshipAcademy wildly]], bring its target to a ridiculously low amount of Life Points, or inflict a one-hit kill. The monsters' laser beam can be stopped by the Lyoko Warriors' defenses, though. In addition, it's stated elsewhere that Aelita loses half her life points every time she uses her Creativity, [[InformedFlaw despite the fact that in-universe there's no evidence to suggest this is true]].
67* AllYourPowersCombined: William's SuperSmoke is Ulrich's Super Sprint combined with Aelita's flight with the added bonus of making him invulnerable. He can also deflect attacks (like Odd), use telekinesis (like Yumi), fire energy (like Aelita), and use at least one form of Aelita's Creativity (i.e. manipulating electronic locks). Finally, he can enter the '''Code: XANA''' in the towers. On top of that, he can NoSell the Digital Sea thanks to that ability.
68* AlmostKiss: Between Ulrich and Yumi in "Routine". Real badly-timed Return to the Past, there.
69* AlphaBitch:
70** Sissi has shades of this. She's the daughter of the school principal with a posse of friends who do whatever she says, and she's not afraid to abuse her connections and popularity to get what she wants. She's ultimately a downplayed example, though. Far from being the queen of the school, most of the other students and faculty don't really take her seriously at all. She's also shown in a more sympathetic light, with multiple episodes showing that she can in fact be a genuinely kind person if she's treated respectfully.
71** A more straight example is [[ParodySue Brynja Heringsdötir]] from "Kadic Bombshell", who is so bad even Sissi can't stand her, primarily because of how she worms her way into Sissi's circle of friends and takes over, pushing Sissi (who is supposedly also her friend) to the side and treating her like nothing. She also starts dating Odd in the episode only to immediately start trying to push him away from his friends. She strongarms him into taking her to the factory where she screws with the supercomputer and ruins Jérémie's latest program. This gets Odd temporarily banished from the Lyoko Warriors, and Brynja refuses to take responsibility for any of it. She then breaks up with Odd anyway when he decides to prioritize saving his friends' lives over [[ItsAllAboutMe hanging out with her]].
72* AlwaysSaveTheGirl: Particularly in Season 1, when Jérémie would rather risk XANA destroying the world than turning off the supercomputer and losing Aelita. The Lyoko-Warriors' strategy to deal with every attack also is a rare ''justified'' example of this trope: protecting Aelita first is the wisest decision because as long as they can get her to the Tower before anyone gets killed, the attack will be stopped and any damage fixed by the [[ResetButton Return to the past]].
73* AmbiguousGender: XANA. Though it makes sense that XANA is an A.I. and thus neither male nor female. Still, characters tend to refer to XANA as "he" or "it".
74* AnimalsLackAttributes: Averted. Odd's dog Kiwi is most definitely not neutered, as evidenced by the two lumps between his hind legs.
75* {{Animesque}}: Not especially in style, though some of the episodes' plots could have come from a Shounen manga.
76%%* AppliedPhlebotinum: In spades.
77* ArbitrarySkepticism: William, in episode 40 "Attack of the Zombies", having just accepted that the cafeteria is being attacked by zombies, refuses to believe Jérémie's explanation that it's being caused by an evil supercomputer and that they have to get to the factory right away.
78* ArtEvolution:
79** Lyoko looks a lot different in Season 1 than from Season 2 onwards. In Season 2 they removed the lighting effects, made the colors a lot brighter and removed various background details.
80** The 2D animation changed too, in the earlier episodes the colors were darker and the movement and the design of the characters was different. In Season 2, the colors became lighter and the designs straightened, and in Season 3 the movement of the characters became sharper.
81* ArtificialHuman: Played straight with Polymorphic Clones, who are extensions of XANA's consciousness that take on a human shape. Subverted with Aelita, who turns out to have been a HumanAllAlong.
82* ArtisticLicenseChemistry: One episode has XANA weaponize laughing gas, which is portrayed much like [[ComicBook/TheJoker the Joker's venom]], making the victim laugh uncontrollably to the point they cannot breathe. In reality, Nitrous Oxide is merely an analgesic that can also induce euphoria. Characters that were overdosed wouldn't start laughing, but experience symptoms like nausea and fatigue instead. And no, drinking water wouldn't make the analgesia go away either.
83* ArtisticLicenseNuclearPhysics: Most of episode "Seeing Is Believing", and any episode thereafter that mentions the nearby nuclear power plant.
84* ArtisticLicensePhysics:
85** In "Zero Gravity Zone", Jérémie proposes that XANA's anti-gravity power-of-the-week works by offsetting "the magnetic attraction of the Earth".
86** In "The Trap", Odd grabs a metal bar to defend Jérémie and himself against a possessed robotic arm in the factory. The arm then grabs the bar and twists it all to heck, while Odd is still holding it.
87** Any time someone throws a skateboard ahead of them so that it starts rolling, while in the same motion jumping onto it (legs offscreen).
88** If Aelita disables a tower the instant before something hits something else in the real world, both somethings will come to an instant stop and the collision will be avoided by about half a centimeter.
89* ArtShift: Some flashbacks (mostly of Aelita's previous life) are rendered with still frames in a graphic style more pronouncedly {{Animesque}} than the rest of the show.
90%% The switch between CGI and standard animation is not Art Shift, it's Medium Blending. Please don't confuse the two.
91* AsYouKnow: Rather frequent, especially in Season 1, since the series starts InMediasRes. Jérémie is usually the one stuck with frequently reminding his friends about information that they would already know -- like the basic properties of the world of Lyoko, the monsters' stats, the fact that they couldn't let anyone die before a Return to the Past or that their main goal is to materialize Aelita.
92* AttackItsWeakPoint: XANA's logo on all his monsters is the best place to hit if one wishes to kill them.
93* AttackOfTheFiftyFootWhatever: XANA gets an A for creativity with this one, turning a teddy bear into a giant, murderous monster.
94* AttackReflector:
95** The {{Slow Laser}}s of the monsters can sometimes be reflected by Ulrich's swords, Yumi's fans or Odd's shield (and even by the landscape in the Ice Sector). Though not the most common tactic, it is occasionally used by the heroes (most often Ulrich) to destroy monsters, especially when they're out of immediate striking range.
96** In episode "Music Soothes the Savage Beast", a mirror is used to send back the lightning attacks of XANA's specters.
97* AuthorAvatar: As noted on the fan forum Lyoko Freak, the [=SubDigital=]'s members bear a striking resemblance to the executive producers of the show.
98* BadassFamily: The Hopper/Schaeffer family is full of people brilliant in brains and brawn:
99** The mother is barely seen in the original show, implied to simply live an ordinary life as the mother of Aelita, but in its sequel Evolution she is retconned into being a scientist good enough to work on Project Carthage. If looking at the ''Code Lyoko Chronicles'' novels instead, she also helped the Lyoko Warriors and XANA defeat [[BigBad Hannibal Mago]].
100** The father, Franz Hopper[[spoiler:/Waldo Schaeffer]], not only worked on Project Carthage, but also successfully evaded the Men in Black with his daughter Aelita, created an entire virtual world known as Lyoko, created XANA, provided vital information and help to his daughter and her friends to ensure the rebellious XANA's defeat, and did it while stuck in the Digital Sea for most of the time.
101** The first child, Aelita [[spoiler:Schaeffer]], is, even prior to her graduation to ActionGirl status in Season 3, a TeenGenius and ActionSurvivor ,as well as the 2nd most powerful Lyoko-warrior and 2nd smartest Lyoko-warrior, with only William and Jérémie surpassing her power and brains respectively.
102** The second "child", XANA, an AI who gained sentience, is an insanely brilliant mastermind who pulled a two-season long XanatosGambit on the Lyoko-warriors, stalemated or defeated them at the end of every season barring the 4th one, nearly killed them a lot of times and even at the cost of its life, succeeded in killing Franz Hopper.
103* TheBadGuyWins: This show is an extreme example. [[spoiler:Every season except the last ended with either a stalemate either a victory for XANA, and the heroes spent most of the next season trying to undo their loss, only to be handed another crushing defeat at the end of ''that'' season. In fact, in the end, it is Franz Hopper, not the protagonists, who took most of the credit for truly defeating XANA. And even with that in mind, XANA still achieves some form of victory by killing Franz Hopper as it planned to during the season.]]
104* BatmanGambit: A few of XANA's plans fit in later seasons.
105** The first example is in "Missing Link", where the Scyphozoa attacks Yumi and steals her DNA code, making her unable to rematerialize. Aelita volunteers to give Yumi ''her'' DNA code, unwilling to let Yumi become the same prisoner of Lyoko that she was... But this was [[spoiler:exactly what XANA wanted her to do, because if she had done so, Aelita's memories would have become exposed and easier to take. Fortunately, the team stops her in time, and gains Yumi's code back another way.]] This may have elements of a XanatosGambit too. Taking Yumi's DNA gave her the same vulnerability as Aelita (meaning she would vanish forever if her life points ran out) so XANA likely targeted her specifically as part of a back-up plan to eliminate Yumi if the first plan didn't work. After all, he had given a lot of attention to her before. (See DesignatedVictim below.)
106** In "Franz Hopper", a polymorphic spectre convinces Yumi that she is suffering from cell degeneration due to repeated exposure to the scanners. This immediately causes everyone in the group except Aelita to resent Jérémie, who feels isolated and is eventually dispelled from the group. Without the boy's interference, XANA traps the three warriors on Lyoko and prepares to do the same to Aelita. The program would have won, except for an even bigger gambit on Jérémie's part: Upon realizing "Franz's" treachery, he has Aelita send a copy of herself into Lyoko, whose memories debilitate the Scyphozoa upon being drained. This leads to the spectre breaking down in a rage that disarranges its physical body, letting Jérémie access the Supercomputer and launch a counterattack.
107** A large part of his plan in Season 4 is a BatmanGambit. William seems determined to subdue Aelita and throw her into the Virtual Sea; the other heroes assume that this is simply XANA's way of eliminating her for good until he actually succeeds in "Distant Memory". [[spoiler:Franz Hopper appears to rescue her, at which point a mob of XANA's monsters springs out and attacks him. It is all part of a plot to lure him into an ambush, as XANA knows he would rescue his daughter. Fortunately, the heroes learns from this, and Aelita is even able to use her DecoyGetaway trick when William tries it a second time.]]
108* BeatTheCurseOutOfHim: In the episode "Valentine's Day", XANA slips Aelita a HypnoTrinket. To force him to relinquish his grip on her, Odd shoots her repeatedly, until she is within an inch of her life. XANA surrenders, as he needs her alive as much as the children do.
109* BerserkButton:
110** Never question Milly when having an interview.
111** Don't insult Odd with food.
112** Yumi has two, both related to her Japanese roots: do not mistake her nationality (especially mistaking her as Chinese, as Sissi got a nasty earful from it), and do not trash-talk Japan or its culture (Jim got a DeathGlare from her when he called manga "Japanese mahn-goes").
113** Don't tell Aelita to forget her past (Jérémie got an earful by advising her to "think like [he does].")
114** Do not mess with Jérémie's programs on his computer when he isn't around. (Odd accidentally pressed this by doing ''nothing with it'' and still got yelled at.)
115** Insulting Ulrich's friends appears to be his, as he takes his father's insults passively until his friends are accused of being a bad influence.
116** Do ''not'' refer to Lyoko as a [[NotAGame video game]]. Every time a character learns about Lyoko and refers to it as a video game, expect ''one'' of the warriors to snap at them.
117* BetaCouple: Jérémie×Aelita as a more stable parallel of the Sissi/Ulrich/Yumi/William Love Tetrahedron.
118* BetweenMyLegs: Happens twice with Aelita, first with Sissi in "Unchartered Territory" and then with William in "Wreck Room".
119* BickeringCouplePeacefulCouple: Yumi and Ulrich as the bickering couple, and Jérémie and Aelita as the peaceful one. Once [[LampshadeHanging lampshaded]] by Aelita, who wonder why Yumi and Ulrich are at odds while liking each other. Jérémie answers her that [[BelligerentSexualTension people who love each other sometimes fight.]] But Aelita then point out that Jérémie and herself never argue.
120* BigEater: Odd. And he seems to have a metabolism like a blast furnace, because he never gains any weight.
121* BilingualBonus:
122** Yumi's teacher speaks Italian in "Tidal Wave".
123** Odd sometimes uses Chinese when greeting Yumi (which ticks her off because she's Japanese, to make matters worse, he even does this in "A Fine Mess" while in ''Yumi's'' body to her own family).
124** Odd appears to be quite proficient in Italian as evidenced in "Attack of the Zombies".
125** Odd also uses Russian in one episode.
126** Yumi likewise is capable of speaking French, in addition to her native Japanese.
127** The names of the days in the time-skip episode appear in French on screen (Lundi, Mardi, Mercredi...).
128* BittersweetEnding: [[spoiler:Although XANA is eventually destroyed, Franz Hopper goes down with him. William also gets his own, as he never got a chance to take his revenge on XANA.]]
129* BladeBrake:
130** Ulrich does this in "Bad Connection" to prevent both himself and Yumi from falling in the Mountain sector.
131** Odd in "[=TeddyGozilla=]" with Aelita, only with his claws in the Desert sector.
132* BlindIdiotTranslation: The fourth season got hit with this when it was dubbed in Brazilian Portuguese. Sometimes the errors are rather tame, like Ulrich saying "Super Hop" or "Super Propulsion" instead of Super Sprint, but then there are the episodes where characters talk as if XANA was a female human, or even worse, call Aelita a "he".
133* BloodlessCarnage: Seeing as most of the fighting takes place in a virtual world, this can be expected. When characters are injured in the real world, we typically see nothing more than minor ClothingDamage where a wound should be.
134* BoardingSchool: Interestingly, the school the children go to is heavily visually based on real locations in Boulogne-Billancourt, France. It isn't a boarding school in real life though; the writers consciously changed that to keep the characters together (even though one does live off-campus).
135* BodyCountCompetition: Ulrich and Odd have the friendly competition kind ongoing about who kill the most of XANA's monsters. In episode "The Pretender", backed up by statistics, Jérémie declares the winner of the month to be... Aelita, to Odd and Ulrich's dismay.
136* BodyHorror: Don't put two living beings inside one scanner at the same time. Their DNA will merge, ''Film/{{The Fly|1986}}''-style.
137* BodyUploading:
138** The "Virtualization" process lets the characters go into a supercomputer, and grants superpowers while in that world.
139** In the AlternateContinuity of the novelizations, it only works on children, as adults, other than Franz Hopper, the creator of the system, using it GoMadFromTheRevelation, due to the Lyoko form reflecting their inner, true self, with a [[ChildrenAreInnocent child's innocence]], a.k.a, a lesser amount of regrets, mistakes, and horrors, keeping them from turning into a monster and undergoing a HeroicBSOD.
140* BondVillainStupidity:
141** In "Revelation", a polymorphic spectre ambushes Odd in the hermitage. Rather than off him then and there, the spectre abandons the boy in a well that slowly fills with water, intending to have him drown. When its cover is exposed, Yumi has more than enough time to find and save her friend.
142** An even worse one is in the episode "Franz Hopper". XANA's spectre has disabled the materialization program, destroyed the Lyoko warriors' weapons and apparently left Aelita stranded on the Desert Sector to have her memories drained. Jérémie confronts it and exposes its true identity, causing the creature to push him aside. Rather than finish the boy off, XANA calmly sits down and starts taunting him about how he has lost... cue Aelita revealing her BatmanGambit and sending the Scyphozoa into a seizure. This in turn causes the spectre to suffer a VillainousBreakdown, the anger and disbelief at being tricked causing its body to destabilize just long enough for Jérémie to take control of the Supercomputer and assist his friends in stopping XANA's attack.
143* BootCampEpisode: In the episode "I'd Rather Not Talk About It", the Lyoko Warriors go to boot camp under Jim to get in shape.
144* BottomlessMagazines:
145** Subverted with Odd. He clearly does not have an unlimited supply of Laser Arrows, and ends up running out after only firing ten arrows. In the second season, however, Jérémie upgrades his Lyoko form so that he has a far greater supply of about ten thousand at once.
146** The trope is played straight in "False Start" where Jim uses a nail gun to fight Xana's monsters, and never has to reload it.
147* BoxingLessonsForSuperman: The Lyoko Warriors go to boot camp under Jim in one episode to get in shape. It isn't much help on Lyoko, but learning to run faster and farther in the real world is quite helpful when faced with physical threats from XANA.
148* BrickJoke:
149** In "Image Problem", Jérémie makes a passing, non-serious remark about the scanners becoming a health problem (in reference to [[spoiler:Yumi/XANA]] being unable to tell the rest of the group what happened before getting devirtualized unconscious). In "Franz Hopper", [[spoiler:XANA masquerading as Franz "confirms" that the scanners are having a negative effect... on [[DesignatedVictim Yumi]].]]
150** In "A Fine Mess" (which, as mentioned below, is ''Code Lyoko'''s FreakyFridayFlip), Jérémie points out that if Odd and Yumi go back into Lyoko and are devirtualized, the program might mess up again and they'd end up with no bodies at all. In season 3, "Nobody in Particular" sees exactly this happen to Ulrich (complete with XANA taking over his Lyoko-bound body...).
151** In "Frontier," Yumi spies a plane up in the sky, worried about XANA attacking while Jérémie is on Lyoko apologizing to Aelita. Cue "Guided Missile" in where XANA possesses control of a fighter jet with the boy in it.
152* BrownNote: The song XANA made in "Killer Music" causes slowed heart rate, coma (though eyes remain wide open), and a Joker Gas-like creepy smile.
153* ButtMonkey:
154** Sissi. She's supposed to be the AlphaBitch, but you would be hard pressed to find a character outside her cronies and father that doesn't enjoy constantly insulting her to her face. This gets awkward when the prequel comes around and it's revealed that she's basically involved in a kind of ViciousCycle, acting like the AlphaBitch in response to the bad treatment she gets from everyone else, which is essentially a response to her AlphaBitch behavior. [[spoiler:The Lyoko kids do manage to break this cycle in the finale, and Sissi does prove that she's been a JerkWithAHeartOfGold all along.]]
155** Odd gets little respect and is constantly failing at various goals he pursues, such as holding on to a girlfriend (though, to be fair, it doesn't help that he dates multiple girls at the same time). He also is notoriously bad at school that even the teachers mock him for it publicly. Let's not forget the constant dissing he gets from his friends, most infamously them stealing his own virtual pet toy and giving it to Yumi's little brother, who soon afterwards breaks it. And also, as he himself lampshades, he's the sole character whose Lyoko form "looks like a nitwit".
156%% Needs context** Of course, neither of the two above examples combined could make the Butt Monkey magnitude of the show's resident gym teacher, Jim Moralés (but he'd rather not talk about it).
157* CallBack: Jérémie builds a Kiwi-shaped robot in the season one episode "The Robots", which shows back up again [[spoiler:in a Xanafied version]] in season four's "Canine Conundrum".
158* CallingYourAttacks:
159** Odd: "Laser Arrow!"
160** Ulrich: "Impact!"
161** Aelita: "Energy Field!"
162** William: "Super Smoke!"
163* CantCountBullets: A RunningGag is Odd running out of ammo at the worst possible time. In season 4, he is left defenseless against William ''twice'' because his arrow count suddenly dropped to zero. In both cases, it ends badly for him.
164* CantKillYouStillNeedYou: In Season 2, while XANA wants to wipe out the rest of the Lyoko Warriors, he needs Aelita alive until her memory can be taken. This condition has actually caused XANA and the Lyoko Warriors to work ''together'' to protect Aelita on a few occasions. It also happens in Season 4, as he needed her alive to [[spoiler:lure Franz Hopper]], to the point of stopping a perfect attack because it was going to off Aelita as well.
165* CantLiveWithoutYou: Aelita with the Supercomputer in Season 2. XANA ensures the kids can't CutTheJuice on him by linking Aelita to it. She lapses into unconsciousness whenever the machine is turned off -- and a too long interruption can make her heart stop.
166* CardCarryingVillain: XANA, over the course of the series is revealed to be one of these. Given he has no true physical form, we only learn this via his actions the rare times he speaks through a polymorphic specter or XANA-William. He is well aware he is by human definition: evil; and he savors every sadistic second of his attacks.
167* CasanovaWannabe: Odd. He claims to be a ladies man, but every girl that he's dated (which includes most girls in his age group at the school) say otherwise.
168* CastFromHitPoints: The bulk of Aelita's powers cost half her life points per use until she gains the Energy Field attack and wings (both free).
169* CatchPhrase:
170** Aelita: "Tower deactivated."
171** Jim: "I'd rather not talk about it." This is even [[LampshadeHanging lampshaded]] at the beginning of the third season.
172** Odd: "[[InsistentTerminology I'm not scrawny, I'm svelte.]]"
173** Jérémie: "Virtualization!"
174** They have further catch phrases in French that didn't necessarily cross over the English version:
175*** Yumi: "Banane !" and "[[SarcasmMode Sympa, l'accueil. Très sympa.]]"
176*** Odd: "T'y crois pas !"
177*** Sissi: "Crétins !"
178%% The spaces before the exclamation points are the correct French punctuation.
179* CatGirl: Both Odd Della Robbia's virtual Cat Boy avatar, and Odd-as-Yumi CatGirl cosplay (see FreakyFridayFlip).
180* CharacterDevelopment: Many characters on the show.
181** Aelita goes through the most out of all of the characters, becoming increasingly less naïve, less [[MartyrWithoutACause impulsively selfless]], more worldly wise and much more of an ActionGirl as time goes on.
182** The [[HeWhoMustNotBeSeen never-seen]] XANA. Initially, all he tries to do is wreak havoc with little to no forethought. From season two onwards, he has clear objectives which he puts a lot of thought into fulfilling. In addition, he becomes more powerful with each season.
183** Sissi gets a lot as well. In "Frontier", she can't stand the thought of helping Yumi, and insists that Ulrich date her for several weeks. Later, in "Missing Link", [[LovableAlphaBitch she's prepared to help Yumi for no reward whatsoever]]. Her role in the two-part prequel further helps develop her character, her relationship with the heroes improves throughout the series, and by the end, [[spoiler:her becoming an "official" friend just feels RIGHT.]]
184** William, even though it's more subtle. He starts out as Ulrich's rival for Yumi's heart, almost turns into a StalkerWithACrush to Yumi in Season 3 (even though he doesn't actually stalks her) who has trouble taking no for an answer, and matures in his few appearances in Season 4 as himself, actually able to take a no for an answer, and ready to seriously helps the Lyoko-warriors despite them rejecting him.
185** More subtly, the group as a whole becomes a lot closer throughout the four seasons. In earlier episodes (especially before Aelita was materialized), the group are often very disjointed to the point where it's questionable if they even ''like'' each other. By season four, they've managed to evolve into TrueCompanions (partly out of necessity), and while there are still frequent TeethClenchedTeamwork scenarios (RuleOfDrama at play), they always forgive each other in the end.
186* CharacterizationMarchesOn:
187** In the first episode, Milly was insecure to the point of coming across as psychotic, getting emotional at the drop of a hat, and talking to her teddy bear when she's alone. For most of the series afterward, she's a perfectly normal girl.
188** Jim was portrayed as ''slightly'' rougher around the edges in Season One compared to the rest of the series plus his "I'd rather not talk about it" catchphrase didn't exist.
189** Sissi was never especially book smart early on, but most of her manipulation tactics the first season highly implied she, at least, had a fair amount of street smarts and was admittedly pretty crafty albeit underhanded. Most of this vanished when Season Two came along, which turned her into more of a bumbling ditz whose strategies barely got off the ground before Ulrich or somebody else shot them down. Her vindictiveness was also toned down as she became a kinder person.
190** Odd, while always portrayed as a jokester and bad at school, was, similar to Sissi, shown to have some basic street smarts and had a future-flash ability that implied he was a bit more complex than what the audience was meant to believe. Come Season Two, he was dumbed down considerably and the future-flash was never seen again until a throwaway exchange in Season Three explained it away as Jérémie accidentally deleted the ability and never restored it due to its inherent uselessness.[[note]]Any time Odd would have a vision, it always came to pass with no chance of it ever being defied. The first instance of it even had him be responsible for the event to occur i.e. Aelita almost plunging to her death.[[/note]]
191** Yumi and Ulrich's [[WillTheyOrWontThey feelings for each other]] was presented somewhat healthier in Season One on the count of Sissi being more unlikable and the absence of [[RomanticFalseLead William]] [[LoveTriangle Dunbar]]. They had their tense moments such as the tail-end of "Frontier" and most of "Routine", but more-often-than-not they seemed more understanding of each other and not so quick to assume the worst whenever Sissi was blackmailing Ulrich.
192** Aelita was initially characterized as a borderline saint and barely emoted beyond what was expected of an (at the time) A.I. unfamiliar with complex emotions, occasionally functioning as something of a WarriorTherapist to Jérémie. Season Two onward, while not sacrificing these traits entirely, gives her more nuances such as playfully snarking/taunting others such as Sissi or the enemies on Lyoko and not above getting frustrated/annoyed with her teammates on occasion, including Jérémie. These subtle shifts become understandable when you learn that Aelita wasn't originally planned to be human during Season One's production.
193** William, in Season Two, is shown to be an adequate swimmer during trips to the pool, but come Season Three when he's hanging off a bridge with Yumi over a canal, he confesses that he can't swim period despite the prior outings.
194* CliffStack: Happens once with a trio of Kankrelats, cementing their status of comic relief among the monsters. Pursuing Aelita in the ice sector, they slide along a frozen tunnel. At the exit, the first two manages to stop before falling down a cliff, but the third one comes too fast and sends them all tumbling.
195* ColorCodedCharacters:
196** Ulrich -- Green (Orange/Yellow in Lyoko)
197** Odd -- Purple
198** Aelita -- Pink
199** Jérémie -- Blue
200** Yumi -- Black (Red in Lyoko)
201** William -- Red (Black/Grey in Lyoko)
202* ContinuityCreep: Starting with the Season 1 finale, the series slowly begins to develop a more serialized story and long-running MythArc, as well as having the characters begin relying less on Return to the Past due to them learning [[spoiler:that each use doubles XANA's power.]]
203* ContinuityNod: Odd's [[BlandNameProduct Tamaguchi]] Jean-Pierre has a brief life in an episode before being unceremoniously thrown away by [[AnnoyingYoungerSibling Hiroki Ishiyama]]. This event is referenced by Odd in the season four episode "A Space Oddity" when he questions Hiroki's fitness to dogsit Kiwi.
204* ContrivedCoincidence: In "The Girl of the Dreams" a girl named Taelia, who looks identical to Aelita, enrolls in Kadic shortly after Jérémie tries out a method to materialize Aelita. They try to contact Aelita in Lyoko just to make sure it's really her, but Aelita happens to have been captured by XANA.
205* ConvenientColorChange: Ulrich's katana usually glows blue when striking or parrying but in the hand of a XANA-controlled warrior (like a Polymorphic Clone, XANA-Aelita, or [[TheDragon XANA-William]]), it glows red instead.
206%%* CoolBike: Ulrich's Overbike.
207* CoolBoat: The ''Skidbladnir'' in Season 4 is a Cool ''Submarine'', that can travel through the Digital Sea.
208* CoolCodeOfSource: The supercomputer screens apparently display a PHP image gallery script.
209%%* CosmicKeystone: The Lyoko Core in Sector 5.
210* CrouchingMoronHiddenBadass: Jim Morales, big time. He might seem like a bumbling gym teacher, but anyone who threatens his students is going to have a bad day.
211* CulturalTranslation:
212** Despite Euro coins floating about, hacked military databases emblazoned with derivatives of the French flag, and even a frigging zoom in from a satellite showing exactly which country they are in, the English dub is adamant about the show taking place somewhere other than a French suburb. The euros are called ''dollars''. Hilariously, in "Attack of the Zombies", Milly mentions a foreign exchange program with France.
213** The Cantonese dub for "A Fine Mess" specifies the type of Chinese into Mandarin that Odd speaks to Yumi's parents and Yumi's reaction to Odd's CatGirl outfit.
214* CurbStompBattle:
215** The first Tarantula to show up beat the whole team at once.
216** When the group fights [[spoiler:Xanafied William]] the first time, he devirtualizes them easily. In the start of Season 4, he still curb-stomp them, and even after his first defeats, he can still put up a fight and even win.
217** The first time Ulrich and Aelita encounters the Kolossus, they are devirtualized within seconds. And all it does to take them out is ''swing its arm''.
218* CutTheJuice: During Seasons 1-2, XANA's schemes aim at preventing the heroes from doing this.
219%%* {{Cyberspace}}: The virtual world of Lyoko, and the Digital Sea in Season 4.
220* DarkerAndEdgier: If compared to the more idealistic song, "Un Monde Sans Danger", [[https://www.youtube.com/watch?v=Wv8S8fU7alc the closing credits for the later seasons]] come off as this.
221* ADayInTheLimelight: Jim gets this in two episodes, "False Start", and even more so later in "I'd Rather Not Talk About It", two rare times when the AdultsAreUseless Trope does ''not'' apply.
222* DeadlyDodging:
223** Before Season 3 Aelita has no proper attack power, and the only real way she can damage the monsters (when not counting on the Lyoko Warriors) is by Deadly Dodging. In Episode 39, "A Bad Turn", alone on Lyoko, Aelita manages to get rid of a whole swarm of Frelions by flying on the [[HoverBoard Overboard]] and having them ram the mountain or each other.
224** This is the main tactic used against the Megatanks. They're invulnerable to the Lyoko Warriors' attacks as long as their two half-shells are closed, but a fall in the Digital Sea will readily dispatch one. Thus, pushing them past a cliff or letting them fall victim to their own momentum whenever possible is the favored option.
225* DecoyGetaway: Aelita has used this trick more than once, creating an illusory clone of herself (or Yumi, in one case) to fool an enemy. It has proven effective on Mooks, the Scyphozoa, and even XANA-William.
226* DecoyProtagonist: Sissi in the two-part prequel. While not as extreme as most examples (she is still a major supporting character), it should be noted that she is introduced before Yumi and has more plot importance and scenes than her in the first episode.
227* DeflectorShields:
228** Odd gains a personal shield in Season 2.
229** In Season 4, the ''Skidbladnir'' and ''Navskids'' are protected by deflector shields.
230** Aelita also creates a BeehiveBarrier in "Replika".
231* DemonicPossession: XANA does this frequently to people, animals, and even teddy bears, through the Specters.
232* DemonicSpiders: [[invoked]]
233** From the group's perspective, Megatanks.
234** Tarantulas started this way, but as the Lyoko Warriors gained experience with them, they stopped being so threatening.
235* DependingOnTheWriter:
236** The level of sympathy Sissi is treated with changes from episode to episode. She was mostly sympathetic throughout Seasons 2 and 4, while mostly unsympathetic in Seasons 1 and 3 (though she still had noteworthy moments in Season 1).
237** Whether or not the gang find Odd's jokes funny.
238** When the scanners are offline, losing all your life points either: a) does nothing, and you remain virtual OR b) leads to your death.
239* DescendingCeiling: This kind of DeathTrap is all-too common in Sector 5, with a few TheWallsAreClosingIn in for good measure. All of the heroes except Aelita falls victim to it at least once, and it happens to poor Odd ''twice''. (The first time, he compares it to being run over by a steamroller.)
240* DesignatedVictim:
241** Aelita is XANA's primary target, although for a different reason each season:
242*** Season 1: Stopping her from deactivating the towers.
243*** Season 2: Cracking her NeuroVault for the Lyoko keys.
244*** Season 3: Possessing her so that she'd [[spoiler:enter the '''Code: XANA''' and delete the Lyoko Sectors]].
245*** Season 4: Throwing her in the Digital Sea [[spoiler:to lure out Franz Hopper.]]
246** Yumi too, for no plot-related reason. It runs throughout the entire series, but it's most obvious in the first half of season 1 (a batch of five consecutive episodes of her being targeted was dubbed "Pick on Yumi Week") and season 3. Of course, maybe XANA ''does'' have a logical reason for wanting to "pick on Yumi": she is the CoolBigSis figure of the team, the most mature of the group, Ulrich's crush (and nearly as good at fighting as him), the least enthusiastic about fighting XANA (she was reluctant to do it in the pilot, and was the most willing to shut down the computer in season 4 finale) and an isolated target due to her living with her parents whereas the others are all boarders at Kadic. This not only makes her a ''much'' easier target than the others, but also means something happening to her will easily crush the morale of her teammates. Given the [[MagnificentBastard manipulator XANA is]], it makes sense.
247* DeusExMachina: In "Cruel Dilemma", Odd drops some candy on Jérémie's keyboard, which [[AssPull somehow types out the exact line of code]] he needed to finish his materialization program. This is, however, portrayed as not entirely positive: the code seems to work, but Jérémie can't check, edit, or duplicate it because the dropped candy also caused it to compile, and some angst is had in the course of the episode as a result.
248* DiegeticSoundtrackUsage: The end credits song beginning season 2 is an in-universe song by the Subdigitals.
249* DigitalAvatar: The characters become this when they enter Lyoko, complete with MediumBlending to 3D.
250* DisneyDeath:
251** Yumi -- once ("Cruel Dilemma");
252** Franz Hopper -- twice ("The Key", "Final Round");
253*** [[spoiler:Subverted in the penultimate episode, "Fight to the Finish", where Hopper sacrifices himself to help the Lyoko Warriors defeat XANA, with no way to undo his death this time.]]
254** Aelita -- thrice straight ("Just in Time", "The Key", "Distant Memory") and a few cases of CantLiveWithoutYou (in Season 2) or {{Decoy Getaway}}s with her clones.
255** Subverted with William in "Final Round". As far as the Lyoko-warriors know, he kicked the bucket in the Digital Sea. Fortunately (or unfortunately), XANA [[VillainousRescue saved him]] in order to turn him into his [[TheDragon Dragon]].
256* DoppelgangerAttack:
257** Ulrich's Triplicate power. Mainly used as a minor distraction in season 1, but a power-up from the second season makes the clones just as powerful as him.
258** In "Final Mix", XANA-Jim temporarily duplicated himself.
259** Aelita can also create clones of herself, but [[DecoyGetaway they're used as a diversion]].
260* DoppelgangerSpin: Ulrich's Triangulate power. He runs in a triangle super fast, creating afterimage clones.
261* DungeonmastersGirlfriend: Jérémie writes a program to calculate "points" scored by defeating monsters. Guess who wins...
262* TheDragon:
263** The Scyphozoa, being a unique monster central to XANA's schemes, fits the role in Seasons 2 and 3.
264** XANA-Aelita becomes a [[CoDragons Co-Dragon]] in Season 3, being a large reason for XANA's victory in that season.
265** Both (while still making minor appearances) are replaced by William in Season 4, though he's NotHimself.
266* DreamingOfThingsToCome: [[spoiler:Aelita in the penultimate episode. She has a vision of her father being killed by a group of Mantas.]]
267* DroolHello: Happens to Sissi in "End of Take", from the [[Franchise/{{Alien}} Xenomorph]]-lookalike animated by XANA.
268* DumbMuscle: Nicolas, albeit with more emphasis on the "dumb" part of the description.
269* EarlyInstallmentWeirdness:
270** Not only is Season 1 almost completely different to the rest of the series, complete with a StrictlyFormula format for all but the two-parter at the end of the season[[note]]On the DVD release, ''the episodes are out of order despite being '''numbered''' in the title cards''[[/note]], but the very earliest episodes also feature some strange nuances. The voice acting is very different, for a start (Odd and Sissi had different voice actors, and Jérémie's voice actor hadn't found the right pitch for the boy yet), and certain aspects of Lyoko act differently, such as Ulrich's clones being able to fight (rather than just being decoys), Megatank lasers not being one-hit kills, and Hornets having an acid attack for a couple episodes.
271** The Italian Dub of Season 1 exclusively referred to the Supercomputer as "Supercalcolatore" (supercalculator), later seasons dropped this entirely and simply referred to it as Supercomputer.
272** They also seem to have had some early trouble figuring out Odd's moveset. The first episode has him use the move Impact to damage an enemy at point-blank range without expending ammo, but this move was later given to Ulrich. In addition, his laser arrow attack looked like actual arrows in the first episode rather than just being the arrowheads from then on. Another early episode has Odd repeatedly [[CallingYourAttacks call out the phrase]] "Laser Flash" when using his Laser Arrow move. And then there's his "[[{{Seers}} Future Flash]]" ability which gave him glimpses of future events, which sounds useful until you realize he couldn't control it, and it immobilized him for several seconds while he had his vision making it useless in combat. It wasn't even particularly interesting from a narrative standpoint, which is why it was worked out in later seasons, with the season three episode "Triple trouble" mentioning that Jérémie deleted it by accident when upgrading their Lyoko avatars and then never bothered reprogramming it because he thought it was useless.
273** Season 1 overall is extremely inconsistent with where the [[ResetButton Return to the Past]] bubble even comes from, as if the animators are just thinking, "It comes outta nowhere; don't think too much about it." It's not until Season 2 and onward that the bubble has an established starting point.
274%%* ElevatorActionSequence: Several times.
275* EliteMooks:
276** The Tarantulas are considered to be XANA's most versatile minions, and they have a 1 to 1 track record when fighting the Lyoko Warriors.
277** Megatanks: after season one, all of them get upgraded to having one-shot-kill lasers. Though they're tougher, they're still easy to fool, especially because they're half-blind while moving.
278* EmbarrassingOldPhoto: Yumi's (dressed as a pink fairy for Halloween) in "Cold Sweat".
279* EnemyDetectingRadar: Jérémie can track both enemies and allies in Lyoko from his screen.
280* EnemyMine:
281** The gang cooperating with XANA's monsters to destroy the runaway "Marabounta". XANA even manages to end the encounter without starting another fight.
282** The situation is ''much'' different when XANA must recruit Jérémie's help in "Common Interest"; with the supercomputer's batteries dying from extended use, XANA possesses a hardened fugitive to kidnap Jérémie and direct him to replace it. [[spoiler:(''This'' time, however, XANA regards it as temporary, and fully intends to order the fugitive to kill Jérémie afterwards.)]]
283* EnemyScan: Jérémie, with the press of a button, can pull up the info of a monster that is on screen.
284* EnforcedColdWar: In Season 1 and Season 2, destroying the Supercomputer would both destroy XANA and kill Aelita, so actually destroying the Supercomputer or Lyoko is out for both sides. Afterward, XANA can attack it.
285* EnsembleCast: The series doesn't have a single main protagonist, all members of Team Lyoko share the spotlight.
286* EpicFail: Without exception, Jérémie causes a disaster whenever he tries to do something outlined in Franz Hopper's journal -- like when he tried to do so in "Marabounta" and a few other episodes. He eventually attributes this to Hopper being such a genius that his notes are just too complicated for him to comprehend properly.
287* EpicTrackingShot: Used numerous times in Lyoko where the animators make liberal use of the 3D free-cam to have it quickly rush across a sector, occasionally even through a tower and into another.
288%%* EpilepticFlashingLights: Any wound on XANA's monsters.
289%%* EverybodyDoTheEndlessLoop:
290%%** The girls in Odd's music video.
291%%** Yumi at the dance during Aelita's first stint as a DJ in "Final Mix".
292* EverybodyKnewAlready: Pretty much every student knows that Odd is hiding Kiwi in his room in defiance of school rules, even though the faculty are clueless. Sissi threatens to tell on him in one episode, but she apparently decides against it.
293%%* EverybodyLaughsEnding: A few times.
294* EveryoneCallsHimBarkeep: The principal's last name ("Delmas") was not revealed until the second season; his ''first'' name (Jean-Pierre) was a mystery until the third.
295%%* EveryoneLooksSexierIfFrench
296%%* EveryoneMeetsEveryone: The prequel episode "XANA Awakens".
297%%* EverythingIsOnline
298* EverythingsDeaderWithZombies: XANA's attack in "[[ExactlyWhatItSaysOnTheTin Attack of the Zombies]]". Thanks to LoopholeAbuse, this is one of the few ways for a Lyoko warrior to be xanafied in the real world.
299* EvilCannotComprehendGood: XANA shows this in "Ghost Channel" when he tries to trick Odd, Urlich, and Yumi by posing as Jérémie. When Jérémie shows up and it turns into a case of SpotTheImposter, XANA insists that Jérémie wouldn't come to Lyoko because he'd be too afraid to; however, this is actually what gives him away, because the rest of the team is certain that Jérémie ''would'' do so, despite being afraid, if their lives were in danger. Note that XANA does eventually prove ''capable'' of Comprehending Good in later episodes, and even trying to take advantage of it. However, it's mostly averted in Season 4, where he often succeeds in luring both Aelita and Franz Hopper.
300* EvilEvolves: XANA gets progressively more powerful throughout the series. He also gets smarter, and more importantly, he also starts learning from his mistakes.
301* EvilOnlyHasToWinOnce: Played straight in Season 1, subverted in Season 2. Afterwards, there are multiple victory conditions for XANA, and not all of them lead to a final Game Over.
302* ExecutiveMeddling:[[invoked]]
303** In-universe example: In "Opening Act", Chris of the Subdigitals points out that this is why they're looking for an opening DJ and why they changed their name from the Subsonics.
304** In "[=TeddyGozilla=]", the school newspaper wanted to take a picture of the area for the school dance, but they weren't allowed to.
305* ExplainExplainOhCrap: In "The Girl of the Dreams", Jérémie rambles to himself about how he gave the Lyoko secret to Taelia, who turned out to be a complete stranger, and in the process realized that the possessed samurai armor was after them and not her; namely Yumi who was still in the school.
306%%* EyeCatch: One for each member of Team Lyoko in each episode.
307[[/folder]]
308
309[[folder:Tropes F to J]]
310* FakeOutMakeOut: In "Replika", Odd and Aelita do this to protect the secret of the Factory from Herb and Nicolas. [[FridgeBrilliance Since the two are pretending to be cousins]], this would give them an [[KissingCousins excuse for doing so off campus]]. (It works too. When Herb and Nicolas tell Sissi later, she thinks that they're crazy, more so when Aelita and Odd continue the charade by pretending to be angry with each other.)
311* FanDisservice:
312** Any "fanservice" provided by Jim Moralès.
313** The infamous scene in "Sabotage" where Yumi is restrained by mutated plant roots. One of them even briefly goes under her shirt and strokes her face.
314* {{Fanservice}}: Oh God, the fanservice. Nearly every main character has had a shirtless/underwear scene of some sort. And yes, it's all in the dub. Which was run on Cartoon Network. In the afterschool slot. With a [=TV-Y7FV=] rating. Remember, though, this is a French television series. The United States (viewing area of Cartoon Network) views nudity and partial nudity as much more risqué as opposed to the French culture.
315** Despite this, Aelita's first two civilian outfits include {{Magic Skirt}}s; for reasons known only to [=MoonScoop=], she has never had an underwear scene (except that time her heart was restarted and she appeared to be wearing a slip). ''Instead'', she is seen stepping into a shower and standing under the water in Season 4.
316** There is even Sissi in her cheerleader outfit, with several frames of animation in which you can ''clearly'' see up her skirt (she's sitting down and crossing her legs). She is also seen walking around her room in her underwear in early episodes
317** In the first episode, she is walking around her room in her pink underwear at about 6 minutes in, for nearly a full minute and a half. A few other things happen during that scene, but it keeps cutting back to shots of Sissi's bra and panties. Quite a way to hook a young male audience in the first episode. Even more interesting, not a single detail was ever edited for the American broadcast ''and'' this episode aired during after-school hours.
318** To recap, we have: CensorSteam, FuroScene, LingerieScene, ModestyTowel, {{Panty Shot}}s, PoolScene, SensualSpandex, ShirtlessScene, ShowerScene, ZettaiRyouiki [-(Yumi in "[=TeddyGozilla=]")-]...
319* FateWorseThanDeath: Falling into the Digital Sea. Yumi and Aelita have fallen in but subsequently been saved, but if there's nothing to save you, [[AndIMustScream you remain virtualized forever, lost in the vast realms of the Internet]]. However, XANA-William [[NoSell no-sells]] it, is stated to live in it and actually uses it as an escape route if he has to.
320* FeatheredFiend: XANA possesses a group of CreepyRavens in "The Pretender".
321* FemaleGaze: PlayedForLaughs. Tamiya zooms in on Ulrich's butt while filming his soccer game. Milly is not too pleased about the quality of her coverage.
322* FetalPositionRebirth:
323** Aelita on her first materialization in "Code: Earth".
324** William after his EvilCostumeSwitch in "Final Round".
325* FeudEpisode: Happens several times to several characters.
326** Yumi's parents in the episode "Laughing Fit", which fuels the conflict for Yumi who dislikes hearing her parents argue.
327** In "Routine", Ulrich begins hanging out with Emily which results in a huge argument between him and Yumi when Yumi believes a lie by Sissi that "Emily and Ulrich have been going out for two months."
328** "Saint Valentines Day" has a similar conflict where Ulrich sees William give Yumi flowers and gets jealous, and spurns Yumi for a fling-date with Sissi, putting the two at odds.
329** The plan XANA employs in "XANA's Kiss" is having a spectre go about taking the form of the various Lyoko Warriors while they kiss random people with the intention of upsetting everyone. Ultimately Jérémie catches onto the ruse when he begins seriously thinking about the situation without being emotionally reactive.
330** In "Aelita", both Odd and Aelita go to Lyoko against Jérémie's wishes due to an argument between Jérémie and Aelita. This ends up being a good thing.
331** In "Replika", Aelita is told by Odd to give a lie about him not being in class. When her lie (Odd being in the infirmary) is proven false, Odd is in trouble for playing hooky, and Aelita is in trouble for lying. Both blame the other for their situation, with Odd mad at Aelita for lying poorly and Aelita mad at Odd for having her lie in the first place because he's lazy.
332** Yumi becomes enraged with her brother Hiroki in "Lost at Sea" when he takes her diary. He tries to make things right, but loses the contents of the diary. Much of the rest of the episode is spent with Yumi trapped on Lyoko thinking about the good times with her brother, and is much softer towards him when she returns. It also helps that Ulrich drops her diary off in her room, leaving her to believe Hiroki returned it.
333%%* FictionalVideoGame: Various video games played by Odd or Hiroki.
334* FindTheCure: Season 2's main plot is curing Aelita of the virus XANA infected her with. [[spoiler:Subverted when the last episode of the season reveals she didn't have a virus at all, she was missing a piece of her memories that was hidden deep into Sector 5]].
335* FireForgedFriends: The team didn't exactly got along and only worked together for a common goal, it's only until later in the series where they looked out for each other.
336* FiveManBandConcert: Several members of the cast form a band in an early Season 1 episode -- Odd on the guitar, Ulrich on the keyboard, Jim on the slide trombone, Nicolas on the drums, and Yumi the singing. Only Odd and Nicolas had any real skill at their instruments, and after that episode, the band was never mentioned again.
337%%* FlyingSeafoodSpecial: The Mantas and Scyphozoa.
338* ForeheadOfDoom: Nearly every character is drawn with a massive forehead. Two of the most notable offenders, Sissi and Yumi, have foreheads that take up more than half of the room on their face.
339* {{Foreshadowing}}: The show is very clever about its foreshadowing, repeatedly putting in hints that will only be glimpsed in hindsight. For an example, one episode has Yumi's parents fighting... the next, [[spoiler:Yumi's dad lost his job and they might be going back to Japan.]] The prequel has a couple references to the first episode as well, which would be counted as foreshadowing if the prequels had aired before season 1.
340** The end credits from Season 2 and on show a folder titled "Waldo Schaeffer", yet the images the folder contains are all about [[BigGood Franz Hopper]], it's not untill way later that it's revealed [[spoiler: that's his real name.]]
341* ForgotAboutHisPowers:
342** Many, many episodes would be over much sooner if Aelita just used her Creativity power to drop XANA's monsters into the Digital Sea while they are distracted. However, considering that this power required half her health to utilize, and especially in the earlier seasons where Aelita would have died if all her health points were depleted, this would have made such a move risky.
343** Yumi could probably do the same with her Telekinesis, though she was never shown using it directly on an enemy.
344* FreakyFridayFlip: Odd and Yumi swap bodies in "A Fine Mess".
345* FreudianExcuseIsNoExcuse: In "Fight to the Finish", the Lyoko-warriors (and more accurately, Yumi, Odd and Ulrich) treats William coldly and kicked him out of the team because he underestimated XANA, and ended up xanafied for a long time as a result, fighting the ones he was supposed to help out. Odd goes as far as to call him an enemy. The implications that they were traumatized and grew used to fight William doesn't help. However, Aelita calls them out on their thinking, pointing out that she was xanafied as well, but they never treated her like they treated William. Sadly, she's mostly ignored, [[NiceJobBreakingItHero and the results are catastrophic]].
346* FriendOrIdolDecision:
347** Conducted in Season 1's "Cruel Dilemma" when Jérémie (with assistance from Odd's candy) creates a [[NoPlansNoPrototypeNoBackup one-shot program]] to materialize Aelita, but must use it to extract Yumi from the Digital Sea.
348** And then the tables turn in Season 4's "Hot Shower", in which Aelita gets herself devirtualized to make XANA choose between letting an incoming asteroid [[GoneHorriblyRight destroy the Supercomputer (and her with it)]] or destroy it with the good old KillSat to give both of them another day (as XANA needs Aelita [[spoiler:to lure out Franz Hopper]]).
349* FutureSpandex: In Season 4, the new {{Digital Avatar}}s of the heroes have a serious Future Spandex look. They were apparently designed by Jérémie, a 13-year-old TeenGenius (except for William, who got his custom-made by ''XANA''). You have to wonder what was going through their minds... though on the other hand, maybe that makes it a JustifiedTrope.
350* GiantEnemyCrab: [[ExactlyWhatItSaysOnTheTin Krabes]]. It should be noted that their [[AttackItsWeakPoint Weak Point]] is on the top of their shells, not under them. Under them is where their pile-driver laser is. Still, they have been stabbed there, even if it didn't do the job.
351%%* {{Giant Flyer}}s: Frelions; Mantas
352* GiantMook: The Kolossus, introduced during the climax of season 4, is taller than a tower.
353%%* GoddamnedBats:[[invoked]] From the group's perspective, the Frelions.
354%%* GoodColorsEvilColors: XANA has a thing for the color red.
355* GoryDiscretionShot: Kind of. If an avatar is stabbed, the show usually censors the blade piercing the body. As a result, all we see are the polygons that make up the Lyoko Warrior scattering around like blood drops, followed by a limb or two disintegrating as the character is devirtualized. While it was rare in previous seasons, it became quite frequent in seasons 3 and 4, due to William's extremely brutal devirtualizations.
356* GratuitousDiscoSequence: In episode "Straight to the Heart", it is revealed that Jim is a former Disco dancer. Though he considers this an OldShame[[invoked]] at first, in "William Returns" he gains some fans and makes a return as "Paco, King of Disco".
357* GratuitousJapanese: "Lyoko" is "travel" in Japanese. Due to the pronunciation of the word and the Japanese lack of usage from the letter "L" they would however pronounce it "ryoko".
358* GrayIsUseless: In "Sabotage", Ulrich's virtual avatar is affected by a glitch that turns him black and white. While in this state, he is unable to fight, as all his attacks pass through enemies harmlessly.
359* GreaterScopeVillain: Project Carthage and the Men in Black. Also overlaps with VillainOfAnotherStory, because (at least on the animated series -- ''Evolution'' is another story) Team Lyoko never encounters them.
360* TheGreatestStoryNeverTold: This was [[LampshadeHanging lampshaded]] a couple of times throughout the series. The group has been risking their lives fighting XANA and saving the world for years, and no one will remember it but themselves. A minor example occurs in "Maiden Voyage", where the incredibly nonathletic Jérémie scales the dorm roof of Kadic to get to his room due to a fire safety drill prohibiting access to the building. Odd (jokingly) correctly guesses that Jérémie did that, but nobody actually believes him.
361* GreyGoo: Jérémie inadvertently nearly creates this kind of disaster in "Marabounta", when he tries to use Franz Hopper's journal to use a weapon to destroy XANA's army. Naturally, the thing goes out of control (leading to a chilling scene where Yumi is EatenAlive by the thing and devirtualized trying to protect Aelita), forcing XANA to enter an EnemyMine situation with the heroes to save Lyoko and Aelita (as he still needs her alive at this point). This was one of several times that Jérémie made a mistake using Hopper's notes, which were clearly too complicated for him to understand. (It wouldn't be the last time.)
362* GroundhogDayLoop:
363** "A Great Day". XANA takes over the return to the past, forcing the Lyoko warriors to re-live the same day over and over.
364** And Franz Hopper, voluntarily, on June 6th 1994 in the backstory.
365%%* HackerCave: The Lyoko Supercomputer, and to a lesser extent Jérémie's room.
366%%* HalfArcSeason: Seasons 2 and 4 follow this route. Season 3 does as well to some extent, but it's more like "Three-Quarters Arc Season".
367%%* HardLight:
368%%** Polymorphic Clones.
369%%** The translated heroes in Season 4.
370* HellIsThatNoise: The Scyphozoa's creepy noise is something that Aelita quickly learns to dread.
371* HeroicSacrifice: [[spoiler:Franz Hopper sacrificed himself in the second-to-last episode in order to provide the necessary energy to run the XANA-destroying multi-agent program.]]
372* HeroicSuicide: Attempted but thankfully averted. [[spoiler: Fed up with XANA and the threat he poses to humanity, Aelita shuts down the supercomputer. Due to XANA's "virus," doing this causes Aelita to either die or become comatose. Fortunately, Jérémie revives her by reactivating the supercomputer before she's gone for good.]]
373%%* HeroSecretService: Yumi, Odd and Ulrich; especially in Season 1.
374* HeWhoMustNotBeSeen: XANA might qualify, being a bodiless computer program who never physically appears to the heroes except on two occasions (once taking the form of Jérémie, and the other time as Franz Hopper). He could also be considered TheSpeechless as he did not communicate with the heroes at all, except for those two times plus once leaving a text message on Jérémie's phone.
375* HoistByHisOwnPetard: XANA [[spoiler:creating the Kolossus and revealing that he had hundreds of Replikas around the world]] defeated Team Lyoko for one mission, but it also made it clear to Jérémie and the other Warriors that they couldn't stop XANA just by knocking out his Replikas, forcing Jérémie to [[spoiler:develop the Multi-Agent Program]]. In the same episode, XANA pretty much hands a backdoor recovery module to the Lyoko Warriors on a silver platter [[spoiler: when he teleported William as a specter, allowing them to save William once and for all.]]
376* HolographicTerminal: All over the place within towers and the Celestial Dome in Sector 5 (itself neither an actual dome or really all that celestial). The Supercomputer proper also has a Holosphere in the middle of the room, but it's just there for fluff.
377* {{Homage}}:
378** ''Film/{{Speed}}'' in episode "Log Book";
379** ''Franchise/{{Alien}}'' in episode "End of Take";
380** ''Film/TheTerminator'' in episode "The Robots";
381** ''Film/TheMatrix'' in episode "Ghost Channel";
382** ''Film/GroundhogDay'' in episode "A Great Day";
383** ''Film/DawnOfTheDead1978'' in episode "Attack of the Zombies";
384** ''Film/TheBirds'' in episode "The Pretender".
385* HopelessSuitor: And how!
386** Milly and Emily for Ulrich (in Season 1);
387** Sissi for Ulrich;
388** William for Yumi, but really starting with season 3;
389** Herb for Sissi;
390** Johnny for Yumi;
391** Jim in the early stages, for [=Dorothy/Yolande=] till he (and we) learns she is engaged. In later episodes, he seems to develop a thing for Ms. Hertz.
392%%* HorribleCampingTrip: "The Lake"
393* HostageForMacGuffin: Inverted twice, first in "Saint Valentine's Day" and again in "Hot Shower". Aelita tends to be ''both'' the Hostage ''and'' the MacGuffin.
394* HoverBoard: Introduced in the second season. They consist of Odd's Overboard, Yumi's Overwing and Ulrich's Overbike (can hover, but doesn't normally).
395* HulkSpeak: William and other XANA-possessed humans are quite monosyllabic (Polymorphic Clones even moreso). At least, [[{{Masquerade}} once the influence has become obvious]]. (And sometimes, even using words is beyond their means. "YAAAAAAAAAR!") As season 4 goes on, William gets more talkative in XANA mode, eventually being able to speak in complete sentences.
396* HumanPopsicle: Well, sort of... Aelita was trapped inside the Supercomputer for around ten years, during which time she didn't age at all.
397* HypnotizeTheCaptive: Aelita falls victim to this several times, especially in Season 3. Across the whole series, it's happened in exactly six episodes: "Saint Valentine's Day", "Lyoko Minus One", "The Pretender", "The Secret", "Double Trouble" and "Wrong Exposure".
398* {{Hypocrite}}: Both Ulrich and Jérémie, in season 2, went behind the group's back and abused the "Return to the past" function of the computer for the sake of the girl they loved (Ulrich used time travel to cheat at the lottery in the hope that it would keep Yumi in France, and three episodes later, Jérémie abused the time loop multiple times in an attempt to enhance his own intelligence to fix the virus that ties Aelita's life to XANA). In response to Ulrich's time travel, Jérémie (along with the rest of the group save for Aelita) angrily kicks Ulrich off the team (though they later change their mind when Ulrich saves them). Then Jérémie goes on to do pretty much the exact same thing (for more important reasons, but with far more uses of time travel) and not only thinks nothing of it, but never gets called out on it.
399* IAmWho: [[LateArrivalSpoiler Aelita is really]] [[spoiler:the daughter of Lyoko's creator, Franz Hopper.]]
400* IdenticalStranger: Taelia, a one-shot character from the first season, is identical to Aelita (her name is even an anagram). Her personality is a complete antithesis of the main character, though.
401* IKnowYoureInThereSomewhereFight: Yumi does this to William in "The Lake"; it only works for a few seconds.
402* ImperialStormtrooperMarksmanshipAcademy: XANA's monsters rarely hit the heroes... even sometimes at close range or when they are stationary targets. Odd and Yumi also appear to be graduates in the early seasons, though that may just be Frelions acting as GoddamnedBats. Although it depends on RuleOfDrama. When the Tarantula is first introduced, it is very accurate and brings down the whole team. Then in "Revelation", it can't land a single hit on Ulrich while he is busy deflecting a [=XANAfied=] Odd's arrows.
403* ImpostorExposingTest: By Season 4, the kids sometimes check out the eyes of those they suspect to be Polymorphic Clones to see if XANA's symbol doesn't briefly flash.
404* InaneBlabbering: Some victims of XANA's latest attack, occasionally, especially Sissi or Jim.
405* InconsistentSpelling: Xana, XANA or X.A.N.A.? Jeremy or Jeremie? Herb or Hervé? Anthea or Antea? And should you use the accented letters? This one'll put fans up in arms faster than tying Ulrich or Yumi down to a permanent love interest.
406* IndyEscape: The Megatanks sometimes force the heroes into running away from the rolling boulder of doom. Ulrich gets pancaked (and thus devirtualized) once.
407* InMediasRes:
408** The show starts without a {{Pilot}} or {{Premiere}} episode, almost a year after the fight against XANA began. There was no explanation of how Team Lyoko discovered the Supercomputer, programmed their virtual avatar appearances and abilities, or came to meet Aelita, until a two-parts prequel in Season 3.
409** Many episodes also begin in the middle of the action on Lyoko. This strongly implies that not all of XANA's attacks are shown, several happening off-screen. There is even a HowWeGotHere in "Bragging Rights".
410* InnocentInnuendo: In the prequel episode, when Ulrich tries remembering Yumi's name, he mistakes it for Yuri. This is more apparent to her due to her being Japanese.
411* InsultBackfire:
412** From the Season 4 episode "Double Take":
413--->'''Suzanne Hertz:''' Jim! You're worse than the barbarians who burned down the Alexandrian Library!\
414'''Jim Moralés:''' Why, thank you, Suzanne!
415** Also, in "XANA's Kiss". Odd is having his ass handed to him by a polymorphic clone that keeps changing shape, currently assuming Jim's appearance. Odd tells it, "Hey, XANA, if you're going to keep changing appearances like that, do me a favor and turn into a wimp next time." XANA's response? He has it turn into a duplicate of Odd. Of course, being the DeadpanSnarker he is, Odd quickly comes up with a witty comeback to that: "Oh, no. Not him. I know his kind. Small, but tough as nails." (Unfortunately, he's right. It starts to pummel him even worse.)
416* TheInternetIsAnOcean: The Digital Sea, which is how the Lyoko program portrays the Internet. The heroes use a submarine-like vehicle to travel through it. It cannot be swam in, though, since anything that falls into the water has its data scattered and it's nearly impossible to get it back.
417* IntrepidReporter: Attempted by Milly and Tamiya. They're always going after a "scoop," but nobody seems to take their journalism very seriously.
418* {{Invocation}}:
419** Jérémie: "Transfer... Scanner... Virtualization!" and "Return to the Past now!"
420** Odd: "Laser Arrow!" - "Shield!"
421** Ulrich: "Super Sprint!" - "Triplicate!" - "Triangulate!"
422** Aelita: "Tower deactivated." - "Energy Field!"
423** William: "SuperSmoke!"
424** Even Yumi said "Telekinesis" once to activate her power, but it was spoken rather than shouted.
425* IronicEcho: [[JustFriends "Friends, that's all."]]
426* ItsAlwaysSpring: And it never rains, nor is any other climatic phenomenon seen except when relevant to the plot (ex: "Cold War").
427* ItTastesLikeFeet: Said by Odd ''twice'':
428-->'''Odd:''' Hey, what's the matter with the hot chocolate today? It tastes like dirty sweat socks and an old pair of sneakers.\
429'''Odd:''' ... no, the soup tastes like dishwater.
430* TheJailer: When XANA has a reason to take an enemy alive, he uses a Guardian, a monster Aelita describes as a "digital jail". Exactly how it captures a victim isn't known, as both times, it happens offscreen (although Aelita's reaction suggests it isn't pleasant) and once that happens, the prisoner is kept in an unconscious state inside the Guardian, which seems almost indestructible from outside force. However, it seems even dumber than XANA's other mooks, and can be fooled easily if presented with a clone or illusion of the intended target.
431* JustFriends: Yumi [[GenreBlindness actually thought]] this would help ''end'' all the confusion in her relationship with Ulrich.
432* JustInTime:
433** Ridiculously overused in the first season, in which virtually every time XANA is defeated with approximately 0.001 seconds to spare; at one point, a ''laser beam'' is halted inches from Yumi's face when the "'''Code: LYOKO'''" activated. Later seasons toned this down a bit. Actually a Season 1 episode title, although not the TropeNamer.
434** A role reversal ends up occurring in "Lab Rat" when XANA uses William to enter and steal control of the tower the gang is using to translate to the site of the Replika supercomputer with the XANA code. Odd is shown to be a mere one syllable away from firing the shot that would destroy that supercomputer when he and Aelita vanish from the site.
435[[/folder]]
436
437[[folder:Tropes K to N]]
438%%* {{Keet}}: Odd; Johnny
439* KidHero: The heroes are in their early teens. The show can be considered a very dark deconstruction of this trope. The lives of these kids is very bleak due to XANA. They face very real dangers and start to become desensitized to the horrible things that XANA causes. This take on the trope also comes up as part of the plots later with the kids showing their frustration at balancing their teenage lives and stopping XANA. The consequences of having to fight while still being teens who have to attend school begins having adverse effects on their grades and stresses their families (especially Yumi who has a few episodes dedicated to her parents demanding explanations for various weird behaviors of hers which are linked to going to Lyoko). Despite this, It gets to a point that most of them are reluctant to actually shutdown the computer at the end of the series because they are just so used to having to fight and each has an attachment to this life for their own reasons. In the episode "Routine", Ulrich becomes fed up with the constant XANA attacks and decides to do something different to feel a bit better. The next day, he's seen talking to another student (Emily [=LeDuc=]), and Jérémie points out to Yumi that it isn't a big deal given his mood. You'd almost forget for a second they're teens and don't get much socializing outside their circle of friends.
440* KillerRobot:
441** Most notably a ''Terminator'' homage in Season 1 episode "The Robots".
442** An army of them shows up in Season 4, which XANA intends to use to enslave humanity.
443** XANA's materialized monsters in "False Start" and "A Bad Turn" count too.
444* KissMeImVirtual: Yumi acts very romantic towards the William clone, though it's an act to keep Sissi and the newshounds from picking up a trail that might lead to Lyoko.
445* LarynxDissonance: In-universe example in "A Fine Mess", when Odd and Yumi are each rematerialized in the other's body by mistake. Yumi barely even tries to sound like Odd from what we see, but Odd attempts a bad falsetto to sound like Yumi... and despite being the [[CrossDressingVoices only male lead voiced by a man,]] he already has [[VocalDissonance a higher voice than Yumi]] to start with.
446* LaughingGas: In "Laughing Fit", Mrs. Hertz introduces nitrous oxide to the class, also calling it by this trope's name, which forces anyone who inhales it to laugh uncontrollably unless they neutralize it with water quickly. XANA takes control of the gas in an attempt to kill the heroes by making them DieLaughing, which becomes problematic when Ulrich and Yumi are at school without water to help them. Jérémie is forced to run in the sewers on foot because he can't risk staying in the freezing sewer water for too long, and Odd gets a whiff of the gas just before he's virtualized into Lyoko, which severely weakens him and leaves him disoriented throughout the crisis.
447* LaymansTerms: A RunningGag involves Jérémie explaining what's happening using technical computer jargon, prompting his friends to annoyedly ask for "Translation, Einstein!" In "Hard Luck", he gives a ridiculously convoluted (yet perfectly accurate) description of what a mandelbug is, which Aelita simplifies to "unusual problem that we don't know how to fix".
448* LeaningOnTheFourthWall:
449** In episode 29, "Exploration", Ulrich voices his desire to just shut down the Supercomputer and be done with it. This leads to the following comment from Odd:[[note]]Note, though, that "you missed an episode" is a perfectly valid French expression in everyday conversation. Still this trope, here.[[/note]]
450--->'''Odd:''' Uh, you missed an episode, Ulrich. [[AsYouKnow Remember Aelita's carrying]]...
451** And again, in Season 4 episode "Kadic Bombshell":
452--->'''Odd:''' Did I miss an episode?
453* LimitedAnimation: In "Echoes", the scene where Sissi is dragged away by her father is represented by a static image of the girl sliding across the screen, making it appear as if she is floating through the air.
454%%* LimitedWardrobe: Lampshaded in "Ghost Channel".
455%%* LiteralCliffhanger: Very common in Lyoko, and a few times in the real world too.
456%%* LoveAtFirstPunch: Ulrich & Yumi
457* LoveDodecahedron: Ulrich and Yumi are mutually attracted, with Sissi fruitlessly pursuing Ulrich and William pursuing Yumi. Herb in turn wants Sissi. Additionally, in season 1, Emily and Milly both pursue Ulrich.
458%%* LukeIAmYourFather: Franz Hopper and Aelita, except it's done in flashbacks following the lockdown and recovery of Aelita's human memories.
459%%* MagicCountdown:
460%%** The "3 minutes" timer before hitting the key in Sector 5.
461%%** And the detonator in episode "The Secret".
462* {{Malaproper}}: PlayedForLaughs, since Aelita has trouble learning common idioms after losing her memory and spending so much time in Lyoko.
463--->'''Aelita:''' You're as stubborn as a fool!\
464'''Jérémie:''' [[GrammarCorrectionGag It's stubborn as a mule...]]
465%%** Jim is particularly fond of malapropisms in his psyche-up speeches.
466%%** Sissi is prone to this too.
467%%* MalevolentArchitecture: Sector 5 or "Carthage" embodies about every example of this trope.
468%%* MatrixRainingCode
469* MeaningfulName:
470** ''[[FunPersonified Odd]]'' Della Robbia's first name and Ulrich ''[[TheStoic Stern]]'''s surname certainly fit well with their characters.
471** The gym teacher is ''Jim'' Moralès and the science teacher is Suzanne ''Hertz''.
472** Yumi Ishiyama: "yumi" is the Japanese word for bow, as in a bow-and-arrow. As a name, however, Yumi's full name translates to "Beauty of the Stone Mountain."
473** "Sissi" is a nickname, but still very fitting for Élisabeth Delmas, the self-proclaimed "WesternAnimation/{{princess|Sissi}}" of the school.
474** Kadic Academy owes its name to science-fiction writer Creator/PhilipKDick.
475** Taelia's name is an anagram of the name Aelita. [[spoiler:Fitting, considering that Taelia being mistaken for Aelita is one of the central points of an episode.]]
476* MechaMooks:
477** XANA's various monsters on Lyoko resemble real life animals with robotic modifications.
478** Actual robots are deployed by XANA on Earth in Seasons 1 and 4.
479* MediumBlending: The two worlds of the show are depicted in completely different mediums, as to make very clear the transition from the "real" world to Lyoko. Ironically, the "virtual" world rendered in CG has naturally a more "realistic" look than the standard animation of the "real world". [[WillingSuspensionOfDisbelief But you get used to it.]]
480* MercyKilling: The Lyoko Warriors use a non-lethal variant of this many times when one or more of them needs to devirtualize themselves in a hurry and Jérémie can't do it for some reason. Basically, it involves a teammate turning his weapon on the other in order to reduce his or her life points to zero (or two doing it to each other simultaneously, in extreme cases). More than once, Odd and Aelita have saved someone from falling into the Digital Sea this way.
481* TheMenInBlack:
482** The Men in Black chasing Franz Hopper in the flashbacks.
483** And the two unrelated (?) secret agents in "False Lead".
484* MentalTimeTravel: While never explicitly confirmed, this appears to be how Return to the Past works, sending everyone's minds backwards in time and only keeping the memories of those scanned by the Supercomputer. This would also explain why it can't be used to bring the dead back to life, as they would have no consciousness to send back.
485* MindControlEyes: All of XANA's creatures have his eye-like symbol. Those he mind-controls have their irises and pupils replaced with this symbol. Doesn't happen all the time, but they've been caught by flashing the eyes unnecessarily.
486* MirrorMatch: In episode "Revelation", Ulrich has to fight a polymorphic clone on Lyoko, at first looking like Odd, but then taking his appearance, leading to a fierce katana duel.
487* MissedTheCall: In aforementioned prequel episode, it was Sissi, not Yumi, who found the factory with the others. She even planned on entering the "game" later, but before she did [[spoiler:XANA got loose for the first time, and Sissi tattled because this was getting too real. As a result, the whole group was nearly arrested, and the others unsurprisingly agreed to keep her in the dark after returning to the past. Sadly, Ulrich decides to [[NiceJobBreakingItHero be a jerk to Sissi about it even though she doesn't remember what her mistake was]], resulting in her becoming the group's AlphaBitch nemesis for a good long while]].
488* MissingMom: Anthéa Hopper, whose role in this mess has yet to be explained. (She may have been abducted by the TheMenInBlack, but no-one knows why.) The fact that Sissi doesn't have a mother is completely ignored.
489* MissionControl: Jérémie's main role is assisting the virtualized warriors at the Supercomputer console.
490* MistakenNationality: Yumi is repeatedly called Chinese in "XANA Awakens", much to her frustration.
491%%* MobileMaze: Sector 5
492* MonsterOfTheWeek: The first season is ''especially'' this, with most episodes being the kids fending off XANA attacks, without much plot development.
493* MultipleDemographicAppeal: For an action series aimed at 6 to 12-year-old boys, the show has a surprising amount of teenage and older fans of both genders. This can be explained due to amount of Fanservice from both gender, the dark theme, semi-complex plot and the well-rounded female characters balanced out with the male ones.
494* MundaneUtility:
495** Addressed in "The Chips Are Down", when Ulrich uses the ResetButton to rig a lottery ticket and win several million euros. It's completely possible to do this, but not a good idea since each Return to the Past makes XANA stronger. At the end of the episode, [[spoiler:Ulrich donates the proceeds to an African development project, [[StatusQuoIsGod preserving the series status quo]].]]
496** Played completely straight when Ulrich, being a VirtualGhost at the time because of Jérémie's latest bit of mad science, [[DemonicPossession possesses]] Jim to use him as a pawn to keep himself from being knocked down to a remedial class.
497* MutualKill: One of Yumi's victories over William is this, nailing him with her fans in a BoomerangComeback just as he's devirtualizing her.
498-->'''William:''' It's game over, Yumi.\
499'''Yumi:''' For you too, handsome.
500* MySkullRunnethOver: Jérémie tries to use the ResetButton's quantum components to enhance his own brainpower in Season 2. Bad idea to start with, worse because XANA slipped him bad code.
501* NearVillainVictory: This is ''seriously'' the case in "Hot Shower". XANA's plan is so perfect, Jérémie ''actually gives up''. Really! The heroes only triumph because Aelita hedges all her bets on a hunch that XANA will abort his plan if it will result in her death (meaning he'll lose access to Franz Hopper); fortunately, her hunch pays off.
502* NeckLift: Poor Yumi is the on receiving hand of this in "The Robots" by a robot, one of Xana's creations.
503* NervesOfSteel: The ''entire main cast'' has them, with a little HeroicWillpower built in. These kids are 13-14 years old (except Yumi, who's slightly older) and are constantly targeted by an insane computer trying to ''murder'' them. (See the NightmareFuel page for the most extreme examples of why this Trope applies.)
504* NeuroVault: Lyoko's keys were hidden inside Aelita's memory.
505* NeverBringAGunToAKnifeFight: At least not one with Ulrich. You'd think a Jedi Master taught him how to use a sword the way he can deflect laser beams with it. He even does so in the real world once!
506* NeverRecycleABuilding:
507** The kids go to an abandoned factory every episode. There's never any presence of demolition crews, and the plot only revolves around saving the factory from destruction when it's some attack from XANA -- at least in the animated series. The non-canon spin-off comics have one story with a demolition crew about to raze the Factory, before being thwarted by the kids. Ironically, the [[http://www.codelyoko.net/ENG/Pictures_factory.htm actual factory that the series' was based on]] was demolished in 2004.
508** There is also the Hermitage, a posh house in the woods that is left abandoned for 10 years. However, there are some hints of squatting (vandalism, tags on the walls...) and since the first time Team Lyoko visited it XANA was playing poltergeist, this might have chased any squatter earlier and gave it a HauntedHouse reputation.
509* NeverRecycleYourSchemes: XANA, with a few exceptions (like multiple uses of polymorphic clones), never tries the same attack twice. Sometimes, especially in the first season, the group takes action to prevent him from repeating a scheme, but other times you have to wonder why he doesn't just repeat an attack with a few modifications, considering the kids are so often only JustInTime to defeat him, sometimes within a few seconds.
510* NiceJobBreakingItHero:
511** Sissi's entire AlphaBitch personality is a result of [[spoiler:Ulrich, who was more of a {{Jerkass}} back then, mistreating her at the end of the pilot for something she had no memory of doing and shunning her away from him and his friends. To his credit, in the series finale he's the one to mend bridges and let Sissi join the group.]]
512** The entirety of the first season becomes this once it's revealed that, whenever the ResetButton is pressed, XANA gets stronger. While XANA originally was only able to interact with the real world via taking control of objects, electronics, and ''occasionally'' causing some kind of fantastical disease to breakout, a few episodes into the second season showed the program had developed the ability to possess ''people'' and grant them supernatural abilities.
513** Jérémie might be a TeenGenius, but that doesn't mean he's perfect. If he comes up with some brilliant new plan to fight XANA, there's a good chance that it won't work without him having to fix some potentially fatal problems first.
514** In "Ultimatum", XANA takes Odd and Yumi as hostages and decides to lock them in a freezer, prompting the boy to protest that human beings are vulnerable to cold temperatures. A few episodes later, in one of the most impressive displays of its powers, XANA uses this knowledge to summon a blizzard above Kadic, nearly killing everyone in the facility and ultimately forcing Jérémie to trigger a return to the past.
515** Jérémie almost causes them to lose Lyoko and get arrested during the events of "The Girl of the Dreams" when he mistakes a girl named "Taelia" for Aelita. In fairness, there are several clues that help Jérémie's case, but he does the bare minimum research to make sure Taelia is indeed Aelita before introducing her to the supercomputer. She promptly slips away when Jérémie isn't paying attention and informs the principal and the authorities, and had the return trip not fired off, Jérémie would have been busy explaining everything to the police. Taelia, as it turns out, isn't Aelita like Jérémie hoped. She just coincidentally looks similar, so Jérémie, in his eagerness, just reveals everything to a total stranger under the assumption she's Aelita with memory loss when she's actually an orphan unrelated to their situation.
516* NiceJobFixingItVillain:
517** XANA occasionally ends up helping the group by accident. For instance, in "Is Anybody Out There?", Odd gets devirtualized after he finds the activated tower. This proves to be extremely fortunate, because if it hasn't happened, no-one would have been around to type in the code "Scipio", and XANA would have stolen Aelita's memories!
518** A Krabe actually saves Odd's live in an early episode. He is about to fall into the digital sea (which entails permanent death); fortunately, the Krabe devirtualizes him before that can happen.
519** In "A Great Day", Sissi gets proof that Aelita isn't really Odd's cousin, and is going to expose them, with consequences that would certainly be terrible for the heroes and good for XANA. But then XANA possesses her, and in the process of trying to kill Ulrich, she accidentally destroys the evidence.
520* NomDeMom: [[spoiler: Aelita]] eventual reveals offhand that she previously used this. After her father left Project Carthage and wanted to start over, he started going by his middle name and the family started using his wife's maiden name. His first name wasn't revealed on the show itself, but the closing credits sequence suggests it was Waldo, and we know his ([[spoiler:and Aelita's]]) original last name was Schaeffer. Hopper came from her mother. This never becomes a plot point, and when she selects a new last name for herself, she picks Stones.
521* NonActionGuy: Downplayed. Jérémie is never shown fighting on Lyoko and is a pacifist most of the time, but he has pulled some pretty impressive feats in the real world, including knocking out a possessed criminal in "Common Interest". [[spoiler: Out of all heroes, he's with Franz Hopper the one taking most of the credit for having defeated XANA.]]
522* NoodleIncident:
523** Given the amount of times Jim would "rather not talk about it", the man seems to be made ''entirely'' of this trope. It is slightly subverted in the episode "I'd Rather Not Talk About It" (of course), in which Jim ''does'' talk about it, although it's only with Jérémie and we don't get to hear it. Nevertheless, it causes Jérémie to gain a healthy respect for Jim. Even better, at a skate demo, when Jim [[ShownTheirWork shows he is knowledgeable about skateboarding]], it is a time when he ''does'' want to talk about it; rather, he is a little busy and doesn't have time to talk about it right then.
524** Two minor ones are also referred to in the episode "Crash Course". (What exactly DID happen in the gym and at the swimming pool?) Three if you count whatever led to the protocol moniker "Big Fat Cheese-Head".
525* NoOntologicalInertia: ''Nothing'' that XANA controls has any ontological inertia. Once the code "Lyoko" has been input into a tower, anything XANA is controlling (and only what XANA is controlling) will suddenly stop, and then time will reset. At one time, this even applied to a ''laser'' that was being fired at Yumi and suddenly halted ''inches from her face''.
526* NoPlansNoPrototypeNoBackup:
527** Jérémie's one-shot materialization program in the first season. Saving a copy to a disk is apparently out of the question.
528** Lyoko's temporary destruction is a subversion. While the Lyoko Warriors doesn't possess a backup, Franz Hopper does, which he happily provides (it isn't all of Lyoko, just the core, but it gives them a base to restore the rest on). In this instance, at least, one could reasonably assume that storing a backup copy of Lyoko would take an obscene amount of storage space, given the revolutionary hardware hosting it.
529* NothingIsScarier: XANA is a Third Variation Example; somewhat subverted because the heroes ''know'' that he's there and he's trying to kill them. Still, he's an enemy that they can't see or hear, but one that is still more terrifying than any that they can.
530[[/folder]]
531
532[[folder:Tropes O to S]]
533* OncePerEpisode: Season 1 is defined by this: Virtualization on Lyoko... Tower deactivation... Return to the Past, regular as clockwork. Later seasons toned the last part down.
534* OneWheeledWonder: Starting in Season 2, Ulrich has the Overbike, which also flies.
535* OnlySixFaces: Eyebrow shapes and hairstyles vary, but the all the faces are pretty much the same. Except for the adults like Jim and Delmas.
536* OnThree: In "Sabotage", Ulrich, Aelita and Odd are in Lyoko and need to get out. Ulrich comes up with a plan: they'll stand in a circle and each will simultaneously hit one of the others with an attack, so that they'll all devirtualize. But first, Odd asks if they're going on three or after three.
537* OOCIsSeriousBusiness:
538** This happens a couple times, and repeatedly to Aelita during Season 3, as XANA can have her enter a code to outright delete a sector.
539** Typically, once someone is possessed by a Spectre, they become completely unresponsive to questions and conversations. They will take the quickest route to the main group or the objective of the time, do whatever they have to to assure that no threats can interfere, and are not above attacking innocents in the way. They also become superhuman and incredibly aggressive.
540** The main point of the episode "Image Problem" revolves around Yumi behaving incredibly strangely. She becomes aggressive with teachers, only talks about being sent to Lyoko, doesn't seem to respond to normal conversation, and outright flirts with Jérémie in an attempt to convince him. The group is definitely suspicious, but most of them aren't positive of what's wrong, with Jérémie believing it is a PTSD response to their last mission. [[spoiler:Eventually they find out it isn't Yumi, but a Spectre, and Yumi is still on Lyoko and trapped in a Guardian. This eventually leads to a [[MirrorMatch showdown between the two]]]].
541** During the episode "Temptation", Jérémie is seen routinely acting like a jerk to the rest of the crew, refusing to answer questions and generally being defensive and rude. Unlike other instances where Jérémie usually became so out of response to something someone said or stress, here he just acts extremely dismissive and rude to everyone with no obvious provocation, taking even the most innocent question as a direct personal attack. [[spoiler:Eventually the group finds out he's boosting his intelligence with a machine from Franz Hopper's notes, and it's having a negative effect on his behavior, at one point knocking him unconscious. By the end of the episode, he returns back to normal, trashing the device as he realizes he never actually learned a single thing that could help him]].
542** During the episode "Wreck Room", the group realizes that the William Clone is acting a bit aggressive and competitive, something he was never programmed to do. They have the right suspicions, as he becomes violent and attacks the other students.
543** During the episode "Ultimatum", Jean-Pierre simply wanders up and kidnaps Odd and Yumi. Obviously, the school is absolutely horrified at his actions, however it doesn't take long for Jérémie and the group to realize that XANA is clearly behind this, and with a little help from the [[ChekhovsGun EMP]], the principal is stopped, the threat is defeated on Lyoko, and the group launches a return trip to fix this.
544** During "Contact", it takes the group a short bit to realize that Sissi's condition isn't normal, and she is under the influence of some kind of effect from Lyoko. [[spoiler:Once they do figure it out, it turns out Franz Hopper possessed her so he could leave them a message]].
545* OtherMeAnnoysMe:
546** In "Triple Trouble", when Odd is split into three, they fight over who gets to go to lunch, and who has to go to P.E. class. They also ruin a joke by inadvertently repeating it.
547** Another example in "XANA's Kiss". Odd complains to the clone he's fighting, telling it that if it's going to keep changing form, it should turn into a wimp next time. Its next form: Odd.
548** In "Revelation", another Polymorphic Clone pulls a similar move on Ulrich, this time for strategy rather than mockery.
549** In "A Lack of Goodwill", XANA-William is visibly annoyed with Jérémie after seeing his clone for the first time. The good William's reaction in "Fight to the Finish" isn't any better.
550* OverrideCommand:
551** '''Code: LYOKO''' allows Aelita to control the towers, mostly used to deactivate towers controlled by XANA.
552** '''Code: XANA''' is used by XANA-possessed Aelita in season 3 to destroy the sectors of Lyoko.
553** '''Code: EARTH''' is used at the end of season 1 to materialize Aelita in the real world.
554* PairTheSmartOnes: Jérémie and Aelita are the smartest characters on the show, being a TeenGenius and a BenevolentAI [[spoiler:who it turns out was actually also a TeenGenius human girl before she got permanently virtualized by her father]]. They're also shown to be a steady couple from the first episode all the way through to the last.
555* PajamaCladHero: Some of XANA's attack happens at night, and the heroes don't always have the time to get dressed before dealing with the emergency. Notably in the episode "Is Anybody Out There?", where they have to trek to the factory in their nighties. It doesn't matter so much once they reach the scanners, though, since their Lyoko avatars are always fully equipped.
556* ParodySue: Brynja Heringsdötir, Sissi's Icelandic penpal from the season 4 episode "Kadic Bombshell". She's beautiful, popular, and perfect in every way. All the boys want her, all the girls want to be her. She's also shallow and vapid, treats people like crap, and ruins everything she touches to the point that it comes as a bit of a surprise that she's ''not'' one of XANA's specters sent to disrupt the kids' activities. At the end, Sissi sends her off to stay with her cousin in the country in order to not have to deal with her anymore.
557* ParryingBullets:
558** Ulrich is practically the equal to any Jedi Master at doing this, able to use his katana to deflect the energy weapons of XANA's mooks with relative ease.
559** Yumi can also do it with her fans, but she's not as good at it as Ulrich is, and has a tendency to let shots slip through from time to time.
560* ThePasswordIsAlwaysSwordfish: The password to deactivate the towers is the name of the virtual world. However, only Aelita can enter it properly, because she holds the keys to Lyoko.
561* PhlebotinumBreakdown: Statistically rare considering how often the scanners are used; nonetheless, sometimes the problems faced by the heroes aren't due to XANA's sabotages but to some bug of the Supercomputer or wrong manipulation. Notably:
562** A botched virtualization that stuck Jérémie in the limbo between Earth and Lyoko in "Frontier".
563** Switching Odd and Yumi's minds in "A Fine Mess".
564** Toying with a teleportation power that results in [[MesACrowd three Odds]] in "Triple Trouble".
565** Melding Kiwi with Odd in "Dog Day Afternoon".
566** A random bug causing spontaneous devirtualizations in "Hard Luck".
567** Really, just about any time Jérémie tries out a new program he's hacked together, it ''will'' screw up somehow.
568%%* PictureDay: "Missing Link"
569* PillarOfLight:
570** One appears on Lyoko whenever a monster or hero falls in the Digital Sea (save for [[TheDragon William]]).
571** Also occurs at the beginning of a return to the past sequence, when an expending pillar of light bursts from the holographic display in the lab.
572* PlayingSick: A standard excuse to get out of class and go save the world. Oddly enough, the teachers almost ''always'' fall for this, except on one occasion. Of course, they don't remember most previous incidents thanks to the Return to the Past.
573* PlotArmor:
574** The Lyoko Warriors are sometimes shown surviving an otherwise deadly attack if the plot calls for it. One of the biggest examples is Odd not being devirtualized after being slashed in the face by William in the episodes "Replika" and "Bragging Rights".
575** XANA-William is often devirtualized or defeated due to this for example in episodes such as "Bad Luck", where he could've easily dodged the falling pillar with his SuperSmoke, "Replika" and "Bragging Rights", where he should've instantly devirtualized Odd the second the latter was hit by William's Zweïhander (it's not explained how Odd tanked the attack), "Distant Memory" where he could've killed Franz Hopper with one simple SwordBeam, and much, much more episodes. [[https://en.codelyoko.fr/dossiers/skills.cl As codelyoko.fr puts it]] :
576--->In the same way he was on Earth, William is tossed around by the writing... and the writers. He was changed into the most powerful Lyoko Warrior because a super-powerful humanoid enemy to oppose the Lyoko Warriors would be great for the final season of Code Lyoko... And he often lost to his adversaries in illogical ways because he "had to lose" at that given moment. Some defeats were humiliating and clearly justified by a need laid out by the episode's story.
577** In the episode "Franz Hopper", there is absolutely no way XANA should have lost. He's successfully manipulated the group to kick out Jérémie, has Ulrich, Yumi, and Odd trapped on Lyoko without weapons, has hacked the virtualization process so their devirtualization would have actually killed them, has Aelita isolated, and has complete control of the supercomputer. [[NonActionGuy Jérémie's]] chances of defeating XANA's spectre were pretty much nil, so the writers suddenly has him program [[ActuallyADoombot a clone Aelita]] on the fly to take Aelita's place and taunt the spectre, causing it to ''leave the computer unguarded''. This lets Jérémie sit down just long enough to help Ulrich, Yumi, and Odd before the spectre ''comes back'' and starts strangling Jérémie, raising the question of [[WhyDontYouJustShootHim why he just didn't do that the moment Jérémie showed up]].
578* PlotMandatedFriendshipFailure:
579** In "Laughing Fit" Yumi's parents have a falling out for reasons that are never explained.
580** Aelita and Odd have an argument in the episode "Replika", in which Odd is angry at Aelita for not finding an excuse for him to sleep out of a test, while Aelita is angry that Odd expected her to lie due to his laziness. While they do make up by the end of the episode, they keep up appearances of the argument at school to assuage any possible suspicions.
581* PornStash: Subverted. During a room inspection, Jim notices some magazines under Jérémie's mattress. Turns out they're just computer magazines.
582* PosterGalleryBedroom: Includes the obligatory Einstein pic in Jérémie's room.
583* PostKissCatatonia: At the end of "XANA's Kiss", Aelita kisses Jérémie, causing him to seize up and go motionless for a long while as the show goes to credits.
584* ThePowerOfFriendship: Despite frequent TeethClenchedTeamwork scenarios, the only reason the gang doesn't simply shut down the supercomputer in the first two seasons is because they don't want to lose Aelita.
585* PowersAsPrograms: The protagonists' powers really are programmed. Unfortunately for them, the show treats programming realistically, so any addition (even by the team's two {{Teen Genius}}es) is a difficult and time-consuming task -- and may as well induce "bugs" that need first to be worked out (as in episode "Triple Trouble"). On the other hand, XANA, being a superior Artificial Intelligence, can easily boost the heroes' powers -- but since he's the BigBad he reserves this for his mind-controlled puppets. Fortunately for them, what XANA can do from his end is limited by his own processing power. Things get kind of bad when he [[spoiler:escapes to the Internet, and they make him mad enough to create a nearly invincible monster that easily one-shots them.]]
586* PowersThatBe: Until the very end of the show, we do not see XANA, just his influence.
587* PowersViaPossession: People possessed by XANA's specters gain super strength, lightning, and toughness. Jérémie also manages to create his own artificial specter in one episode which gives a person similar abilities, albeit a bit weaker.
588* PrecisionGuidedBoomerang: Yumi's tessen fans work like this. Less commonly, [[ThrowingYourSwordAlwaysWorks Ulrich's sword when thrown]] behaves similarly.
589%%* PrimaDonnaDirector: James Finson in "End of Take".
590* PrincessesPreferPink:
591** Aelita is often said to be the "princess" of Lyoko (hence Ulrich and Odd's nickname for her), and she sure seems to like pink. Even her hair and {{Energy Ball}}s are pink.
592** [[WesternAnimation/PrincessSissi Sissi]] is a [[AlphaBitch self-proclaimed princess]] with pink clothes and underwear.
593* PromotionToOpeningTitles: William in Season 4.
594* ProtagonistCenteredMorality: During the first season, before the show completely found its groove, the heroes could suffer from this. Potentially justified as the characters ''are'' young teenagers.
595** In one episode, Sissi tricks Ulrich by writing a note pretending to be Yumi, [[AndThatsTerrible and that's considered terrible.]] In a different episode, Ulrich and the gang trick Herb by writing a note pretending to be Sissi, [[MoralMyopia and that's considered perfectly OK!]]
596** Another episode put it even further by centering morality around Yumi alone: in this episode, Odd inadvertently publish a embarrassing photo of Yumi in Kadic's newspaper, understandably making her pissed off. Scared of Yumi's wrath, Odd convinces Ulrich to take the blame for him without telling what the blame is. After Ulrich learned it and ended up with Yumi angry at him, he attempts to convince Odd to tell the truth to her, until Yumi assumes he did it because of their UnresolvedSexualTension and forgives him, causing him to [[SureLetsGoWithThat keep the silence after all]]. In the end, Odd finally tells the truth to Yumi, and how does she react? By being pissed off again for them "tricking her" and taking her revenge on ''both'' Ulrich and Odd by publishing a compromising photo of them in the newspaper. [[SarcasmMode Yeah, because Ulrich was so nasty by taking wrongly all the blame for the sole sake of helping his best friend...]].
597%%* PsychicDreamsForEveryone: Aelita [[spoiler:and possibly William.]]
598* PsychicPowers:
599** Aelita's second sight grants her omniscience on Lyoko.
600** Odd's future flash stuns him momentarily as he sees a vision. It's lost after the first season, as Jérémie accidentally erased it and didn't bother programming it, as he felt it was useless.
601** Yumi's telekinesis allows her to move objects and allies with her mind.
602* PubliclyDiscussingTheSecret: The heroes regularly discuss XANA's activities. This has gotten them into trouble a couple times, but because their super-computer has [[ResetButton Return to the Past]] functionality, they're able to undo anyone finding out too much. They also pretend to be discussing some video game or movie when someone happens to inquire about it.
603%%* PuppyLove: Hiroki×Milly
604* RapidFireTyping: Jérémie in every single episode.
605* RealPlaceBackground:
606** In the episode "Guided Missile", Jérémie gives his GPS co-ordinates as N47.4313 E01.3445, which is [[http://maps.google.com/maps?q=47.4313,01.3445&hl=en&ll=47.546872,1.274414&spn=7.119881,21.643066&sll=-25.274398,133.775136&sspn=72.060015,173.144531&t=m&z=6 just south of the city of Blois, in central France]].
607** The Factory is based on an old Renault plant and headquarters located in [[http://en.wikipedia.org/wiki/Boulogne-Billancourt Boulogne-Billancourt]] that was demolished in 2004.
608** Kadic Academy is remarkably similar to [[http://en.wikipedia.org/wiki/Lycée_Lakanal a school a few kilometers away]].
609* RedHerring: In Season 4, the fourth ''Navskid'' (obviously prepared for William) ends up never being used.
610* ResetButton: Nearly every episode, the effects of XANA's attack are undone via MentalTimeTravel. The main kids [[RippleEffectProofMemory aren't affected by it]], but students and faculty who discover them (and become allies or enemies) go back to being ignorant. It's used more sparingly in the second season, after they discover that using it empowers XANA. Even after the link to XANA is severed at the end of Season 2, the Return to the Past is still employed conservatively, if mostly to prevent mucking with the narrative.
611* RivalsTeamUp: In "The Robots", the team enlists Herb's help to create a device to fight XANA's androids, and he actually does a pretty good job. Unfortunately, the Return to the Past trip erases Herb's memory of the event, and ruins any chance of them becoming friends permanently.
612%%* RoboCam: XANA's monsters, robots, Polymorphic Clones, and Specter-possessed people.
613* RobotWar: [[spoiler:XANA has created an army of robots to enslave mankind late in season 4, but is killed just as they are activated.]]
614* RunningGag:
615** "Are you OK? Say something!" "[[ExactWords Something.]]" This gag was started by Odd early in season 2, but then everyone started copying it.
616** Someone from Kadic Academy (Jim, Sissi, Milly/Tamiya, etc.) discovering everything, only for Jérémie to nonchalantly wipe their memories with a Return to the Past.
617** The similarities between any given one of XANA's plans, and the episode plots of the [[ShowWithinAShow fictional TV program]] ''Hospital of Horrors''.
618* SarcasmBlind: In "Final Mix", Sissi is banned by her father from going to the dance party because she didn't study for her exam. Naturally, she ignores this and goes to the dance anyway. Cue the following exchange with [[TheDitz Nicolas]]:
619-->'''Nicolas:''' You snuck out?\
620'''Sissi:''' No, no. My father said, "You're gonna repeat the year, but it's no big deal sweetie. It doesn't mean you can't have a good time."\
621'''Nicolas:''' Is that what he said?\
622'''Sissi:''' ''[agitated]'' Oh you're such an idiot! Of course I snuck out, what do you think?!
623* SadisticChoice: In the very [[ExactlyWhatItSaysOnTheTin aptly named]] episode "Cruel Dilemma," the gang has to choose between materializing Aelita or Yumi who had fallen into the Digital Sea.
624%%* SaunaOfDeath: In "New Order", for a GettingHotInHere moment.
625%%* SaveBothWorlds
626* SayingTooMuch: [[spoiler:The fake Franz Hopper criticizes Jérémie about letting his diary be ruined, something the real Franz Hopper would have had no way of actually knowing, thus revealing himself to be XANA in disguise. This, however takes a bit to register in Jérémie's mind because his whole group effectively turned against him.]]
627* SceneryPorn: Frédéric Perrin's work on the backgrounds used almost endlessly in the animated sequences fits this to a capital "T".
628%%* SchoolNewspaperNewshound: Milly & Tamiya
629* SchoolPlay:
630** The classical ''Theatre/RomeoAndJuliet'' in "Laughing Fit".
631** ''Theatre/CyranoDeBergerac'' in "Temporary Insanity".
632* ScientistVideoJournal: In the episode 52, "The Key", Jeremie shows to his crew the video journal of Franz Hopper. He documents in his journal how he initially created the A.I. "XANA" to counter the military program Carthage. Later on, Franz Hopper hides himself in the world of Lyoko as they are after him, Hopper loses control of XANA, leading to it becoming a threat, as chronicled in Hopper's video log. [[spoiler:Hidden in Lyoko, Franz Hopper is not able to return to the real world]], thus making the journal a vestige of his existence, waiting for someone in the future to find it.
633%%* ScienceFiction
634* SdrawkcabSpeech: In "Contact", it's possible to notice that [[spoiler:the Franz-possessed Sissi]] is speaking backwards. Using software to play it backwards reveals the message [[spoiler:"I can help you! I want to enter into contact with you now. I'm Franz Hopper. I can help you!"]].
635* SecretDiary: Ulrich and Sissi have diaries which appear in "Log Book". Yumi's diary appears in "Lost at Sea". Jérémie's is occasionally shown making video logs of the group's adventures in Lyoko, featuring most prominently in the last episode, "Echoes".
636* SeriesContinuityError: The first part of the "XANA Awakens" two-parter has a moment where Odd deflects a Blok's laser with a DeflectorShield that he creates from his arms. "XANA Awakens" is a prequel that occurs before Season 1, so Odd shouldn't have the shield ability as he doesn't get it as a new skill until Season 2.
637* SetRightWhatOnceWentWrong: If an episode features a return to the past, the Lyoko Warriors will usually do this afterwards, taking steps to prevent a mistake or conflict that occurred the first time around, or making it more difficult for XANA to repeat an attack.
638* ShipperOnDeck:
639** The whole gang for Jérémie and Aelita. They spend season one risking not only their own lives but the entire world so that Jérémie can come face to face with his virtual girlfriend.
640** Yumi's little brother Hiroki for Yumi and Ulrich. Odd also shows hints (he buys Yumi a present in Ulrich's name to smooth out a misunderstanding and gives Yumi a very flattering and heartfelt explanation for why Ulrich might have embarrassed her[[note]]Ulrich ''is'' taking the blame for Odd in this case, so the defense is justified, but he could have gone about it differently[[/note]]).
641** The end credits for the first season include a shot of Jérémie and Odd pushing an embarrassed Yumi and Ulrich toward one another, implying that they're this. For the most part, though, in the actual show they're not.
642* ShockAndAwe: Lightning is a common weapon of Specter-possessed people and Polymorphic Clones.
643* ShootTheDog:
644** The first time that the party dematerialized one of their number [[CriticalExistenceFailure with their weapons]], it looked like this, with Yumi sounding grimly resolute when she suggested it. Later on, as the gang becomes more experienced, it becomes more of an accepted way of salvaging the mission when Jérémie is unable to act.
645** Aelita intentionally invoking '''Code: XANA''' and nuking the Ice Sector in "Sabotage", saving the rest of the Supercomputer.
646* ShoutOut:
647** [=MoonScoop=] has confirmed that Kadic Academy was named after Creator/PhilipKDick.
648** A [[Anime/MyNeighborTotoro Totoro]] plush toy can be seen in Yumi's bedroom.
649** The icons on Jérémie's computer are [[http://starwars.wikia.com/wiki/Aurebesh Aurebesh]], the writing system from ''Franchise/StarWars''.
650** In the episode "End of Take", a film is being shot with an alien that is a blatant rip-off of the [[Franchise/{{Alien}} Xenomorph]]. Ulrich lampshades the similarities and nearly name-drops the franchise's name before being interrupted.
651** In the episode "Attack of the Zombies", Creator/BruceWillis himself gets name-dropped. In an earlier episode "Holiday in the Fog," Sissi describes Jérémie as "[[ClosestThingWeGot The closest thing to]] Bruce Willis."
652** At the end of episode "Vertigo", Odd comments that he would love to turn invisible, like Susan of the ComicBook/FantasticFour. Note that [=MoonScoop=] also produced ''WesternAnimation/FantasticFourWorldsGreatestHeroes'', although this comment predates it.
653** In episode "The Secret", the demolition worker controlled by XANA distinctly looks like [[Franchise/SuperMarioBros Mario]]. William even calls him a "super-plumber".
654** Taking note of Jérémie's attempts to follow in Hopper's footsteps, [[spoiler:XANA]] accuses Jérémie of being "the sorcerer's apprentice", referencing the [[SorcerersApprenticePlot classic tale]] in which a novice sorcerer's lack of skills nearly destroys his master's work.
655** In one episode, Odd comments on being great with women; immediately, a girl walks up to Odd and smacks him; he has just finished commenting on "not knowing what this is about" when another girl, seeing the first, walks up and smacks him for being seen with the other girl. Odd then admits he [[Film/PiratesOfTheCaribbeanTheCurseOfTheBlackPearl might have deserved that one.]]
656** In "The Pretender", when the main characters notice the XANA-possessed crows staring ominously at them, Odd remarks that the scene is eerily similar to "a dumb [[Film/TheBirds flick where birds attack the heroes]]" and adds that it wasn't even scary.
657** Ulrich's katanas glow blue when he fights with them. In the season 4 episode where Aelita is controlled by XANA and she steals one of Ulrich's swords, the katana glows red in her hand. This gives the ensuing duel a very strong [[Franchise/StarWars "Jedi vs. Sith"]] look.
658* ShowWithinAShow: ''Hospital of Horrors''. Though never shown on-screen, from the comments made about it the show sounds like a mix of MedicalDrama and cheesy horror B-movies.
659* SickCaptiveScam: Performed by a specter in "Common Interest" after possessing the criminal Peter Duncan. He feigns passing out in order to get the police driving the armored transport to stop and open the door to check on him, before taking the police out with his superpowers.
660* SkirtsAndLadders: In "Is Anybody Out There?", Odd and Aelita have to rush to the Factory in their nightwear. And when they're climbing down the ladder to the sewer, Odd's gaze is firmly set toward Aelita's pantless nightgown.
661%%* SmartPeoplePlayChess: Aelita & Jérémie
662%%* SnapToTheSide
663* SorcerersApprenticePlot: {{Invoked|Trope}} at one point, when Franz Hopper accuses Jérémie of being "the sorcerer's apprentice" and screwing everything up by using the Supercomputer. [[spoiler:Actually, it's XANA trying to get Jérémie out of the way for his latest plot.]]
664* SoWhatDoWeDoNow: In the final episode, [[spoiler:Odd and Ulrich show reluctance when Yumi proposes shutting down the Supercomputer, as they will miss their adventures on Lyoko and are unsure whether they will be able to readjust to their normal lives]].
665* SpikeBallsOfDoom: Three of these defend the International Space Station taken over by XANA in Season 4.
666* SpinningOutOfHere: The teens rotate in the scanners before being transported to Lyoko.
667* SpoilerOpening: [[spoiler:Inverted. The end credits from season 2 onward involve images of a folder full of information on the character who everyone at the time is referring to as Franz Hopper, but the tag on the front of the folder clearly says "Waldo Schaeffer".]]
668* SpotTheImposter: Happens frequently with the Polymorphic Clones.
669** The first occurrence was with XANA himself impersonating Jérémie in "Ghost Channel".
670** Aelita could tell Jérémie apart from his double in "XANA's Kiss". It happens a second time in the same episode: Odd has to decide between the Polymorphic Clone and Yumi, and figures it out because the real Yumi called him "pea-brain".
671** Jim isn't so lucky with his nephew Chris in "Opening Act".
672* StealthPun: Source material dictates that Aelita was born in the United States. That both means that she was "[[Music/BruceSpringsteen Born in the USA]]" and "An American in Paris".
673* SteppingStoneSword:
674** Happens a few times with Ulrich's katanas; sometimes for himself, sometimes for other characters.
675** Everyone also seems to use William's {{BFS}} for this whenever he gets it stuck in a wall.
676* StockFootage:
677** The first episode reuses some scenes from ''Garage Kids''.
678** In Season 2, footage from Season 1 is used as Aelita deactivates Towers, despite the ArtEvolution making the difference between the old and new models very clear. It's not until Season 3 that new scenes of Aelita in the Towers are used, such as when she starts [[spoiler:deleting the sectors of Lyoko.]] Even then, some Season 3 episodes still use the Season 1 footage when she deactivates towers.
679** Battle sequences on Lyoko are very frequently recycled between episodes. One instance is Yumi's battle against William in "The Lake", which consists entirely of scenes from their previous scuffle in "Wreck Room", only played in a different order.
680* StopOrIShootMyself:
681** A variation is used where Aelita's friends threaten to kill her before the Scyphozoa can MindProbe her (which would kill her too), forcing XANA to order the monster to release her.
682** In "Hot Shower", Aelita sets up a situation where the Supercomputer can't be destroyed without killing her, and XANA aborts his ColonyDrop attempt (as he needs her alive, [[spoiler:so he can lure out Franz Hopper from the Digital Sea).]]
683* StoryBreakerPower: [[ZergRush Triplicate]]. It's the only Lyoko power to not leave the user vulnerable while being performed, provides a solid defense, and the clones are capable enough to curb-stomp XANA's forces on their own (watch "Tip-top Shape" for the best example of this). It got so bad that season 4 [[TheWorfEffect worfed]] it by having William effortlessly counter the ability when it's used against him, thus intimidating Ulrich from using it again [[PutOnABus for the rest of the series]].
684* StrictlyFormula: For the first season, the plot of just about every episode is: Something strange happens around the school. Jérémie correctly thinks it's XANA, Odd doesn't. Jérémie and one or two of the Lyoko Warriors go to the factory. The remaining one or two of the three must stay behind in danger to [[RuleofDrama heighten the drama]]. The virtualized Warriors fight 3-5 monsters while escorting Aelita to the tower. The in-danger team members are saved JustInTime by the tower de-activation plus a Return to the Past. The team returns to a scene from the beginning of the episode, usually PlayedForLaughs.
685* SuperDrowningSkills: Falling into the Digital Sea is immediately lethal for the Lyoko Warriors or the monsters. The backstroke in ordinary bodies of water, however, is perfectly fine for the heroes (but terrestrial monsters can't swim). Although it is confirmed in Season 4 that the Digital Sea is not a literal sea, but rather the edge of Lyoko. Also, it's implied in "Cruel Dilemma" that the person wouldn't actually die, but simply be [[AndIMustScream trapped, unable to return]].
686* SuperstitionEpisode: In the episode "Hard Luck", Odd accidentally breaks a mirror. Ulrich tells him he'll get seven years of bad luck. Odd doesn't believe it and rants about how various superstitions are ridiculous. However, a series of unfortunate events plague him and eventually the rest of the team starts to consider him bad luck. At the end of the episode Odd [[SkepticNoLonger finally admits he is jinxed]], only for Aelita to tell him jinxes don't exist and he has to wait for his luck to change. It does.
687[[/folder]]
688
689[[folder:Tropes T to Z]]
690%%* {{Tagalong Kid}}s: Hiroki; Johnny
691* {{Tagline}}: "Can you keep a secret?"
692* TakenForGranite: XANA tries a something like this in "Triple Trouble", unleashing a fog on the whole city that can turn people into stone. (Which is sort of strange, seeing as it more resembled his MO from the first season, rather than anything related to his goal in the third.)
693* TakingTheBullet: It's frequent in Season 1, especially for Odd, to protect Aelita. Considering who this series is aimed at, of course, the bullets in question this time around are laser beams, and they only cause devirtualization, not permanent death.
694%%* TeamPet: Kiwi
695* TechnoBabble: Second nature to Jérémie and Aelita.
696* TeenGenius: Two, Jérémie and Aelita. Two and three-quarters counting Herb.
697* TeethClenchedTeamwork: Every other episode due to some sort of betrayal, XANA-mitigated or otherwise.
698* TeleporterAccident: The scanners technically don't "teleport" the team, but similar accidents have happened:
699** In "Frontier", Jérémie tries to go to Lyoko to apologize to Aelita after an argument, but Yumi makes a mistake trying to send him there, resulting in him trapped in limbo between Lyoko and the real world, and in danger of disappearing completely. (Rescuing him ultimately requires Ulrich to ''kiss'' Sissi and go out with her for a month.)
700** In "Dog Day Afternoon", Odd tries to take Kiwi with him to Lyoko, only for the scanner to merge them into one body, giving him no end of trouble until Jérémie can reverse the problem.
701** In "Triple Trouble", Jérémie programs a new ability for Odd's Lyoko form to replace the precognitive visions he had lost; unfortunately, this causes the scanners to malfunction when he returns to Earth, causing three of him to emerge. [[OtherMeAnnoysMe (and they can't get along or cooperate with each other at all.)]]
702** In "A Fine Mess", a bug in the scanners causes Odd and Yumi to experience a FreakyFridayFlip; but then it [[FromBadToWorse gets much worse]]. Going to Lyoko like this make them unstable and at risk of [[RetGone being deleted permanently]]. Fixing it requires going to Sector V so Aelita can access XANA's private files in the Celestial Dome access computer, which she does at the last minute.
703%%* TemptingFate: Way too often. Those kids should learn to shut up....
704* TentacleRope:
705** In "XANA Awakens" and "Ghost Channel", XANA possesses electrical cables which then restrain Jérémie.
706** Also, with the Season 3 episode "Sabotage" and the creeping vines, particularly for Yumi.
707** The Scyphozoa's tentacles, however, don't quite touch Aelita when they wrap around her, which happens several times (plus once to Yumi and William each).
708* TerminatorImpersonator: In the episode creatively titled "[[ExactlyWhatItSaysOnTheTin The Robots]]", XANA creates a robot that superficially resembles the exoskeleton of the T-800 to hunt down the heroes.
709* ThanksForTheMammary: Jérémie accidentally "touches" Aelita while she's invisible in "Vertigo".
710* TheyWastedAPerfectlyGoodSandwich: The heroes have regularly to interrupt a meal because of a XANA emergency, despite Odd just hating this to happen.
711%%* ThoseTwoGuys:
712%%** Sissi's sidekicks and fanboys, Herb and Nicolas.
713%%** Also Milly and Tamiya.
714%%** As well as Hiroki and Johnny starting with Season 3.
715* ThrowingYourSwordAlwaysWorks: Ulrich and William are very guilty of this. Ulrich's katana even wanders into PrecisionGuidedBoomerang territory at times.
716* TitleThemeTune: Both in French and English.
717* TomboyAndGirlyGirl: Yumi & Aelita -- or Yumi & Sissi as rivals ([[UnknownRival sort of]]) go.
718* TookALevelInBadass:
719** William initially appeared to be a secondary character to build tension for Yumi and Ulrich's [[LoveTriangle relationship]], merely getting in the way and even [[StalkerWithACrush stalking]] Yumi. Then he enters Lyoko, where he gets a giant sword[[spoiler:, although he gets an [[EvilMakeover evil makeover]] as well after being possessed by XANA.]] He even has SugarWiki/{{Awesome|Music}} [[https://www.youtube.com/watch?v=l3JOuCkc0Gg music]] accompanying his fights throughout Season 4.
720** Also in season 4, after being corrupted by the Scyphozoa, Aelita takes a katana right out of Ulrich's hand mid-attack, and proceeds to [[https://www.youtube.com/watch?v=VYl_rnzP4KY wipe the floor with him]].
721* TooSpicyForYogSothoth: Aelita uses her DecoyGetaway trick to escape the Scyphozoa. The monster is fooled, and tries to use its memory-draining powers on the clone... which results in it becoming sick.
722* TravelingAtTheSpeedOfPlot: The amount of time until XANA's current plot completes is always just long enough that the Lyoko-Warriors will beat it with a couple of seconds to spare, if that. Same with the Sector 5 countdown or the second layer of the Core shield. They rarely run out of time, either; if XANA wins, it's nearly always by defeating the heroes, not just running out the clock. Most JustForFun/{{Egregious}}ly, whenever a countdown clock is seen on the supercomputer, it'll usually be only a few milliseconds away from reaching zero, despite the fact that the Lyoko-Warriors apparently have enough time to stop it.
723* TurnedAgainstTheirMasters:
724** XANA rebelled against his creator, Franz Hopper.
725** And Jérémie walked in Franz's footsteps with the "Marabounta".
726%%* TwiceShy:
727%%** Ulrich and Yumi.
728%%** Also Jérémie and Aelita, to a lesser extent.
729* UnfinishedUntestedUsedAnyway: A lot of Jérémie's gadgets and inventions are created on the fly and immediately put into play on the field. Sometimes this works out, and other times, it doesn't:
730** In "Swarming Attack", he uses a specialized robot to distract and repel the [[BeeAfraid hornet swarm]] XANA has possessed. The batteries give out at the worst possible moment, leading to Ulrich nearly getting stung to death.
731** In "Marabounta", he creates the eponymous program as a means of fighting XANA's monsters and achieving victory much faster. It works well at first... until it detects Aelita's link to XANA, mistaking her for a threat and trying to kill her before becoming autonomous and spreading out of control throughout Lyoko; only through an EnemyMine between the Lyoko Warriors and XANA himself is the creature stopped.
732** In "Nobody in Particular", he creates a program to virtualize the Lyoko Warriors directly into Sector Five rather than having to access it through one of the other four Sectors. The first test separates Ulrich's mind from his body, allowing XANA to possess him and attack Lyoko's core.
733* UnknownRival:
734** Sissi. She considers Yumi her rival, but Yumi for the most part barely acknowledges a rivalry, most likely knowing Sissi is a HopelessSuitor anyway.
735** Also, Herb seems to consider Jérémie a rival in school achievements. Jérémie doesn't notice.
736* UnresolvedSexualTension: Ulrich and Yumi, to the greatest excesses possible in [[AnimatedShows Western Animation]]. [[ShipTease Sissi and Odd]] to a far lesser extent.
737* TheUnreveal: Jérémie's appearance on Lyoko is never revealed to the viewer. The one time he actually virtualizes with no hiccups, he refuses to speak of it afterward, with Ulrich commenting that he looked ridiculous.
738* ViewerFriendlyInterface: In the very frequent event of something going wrong on Lyoko, Jérémie's computer typically displays a massive flashing "!" accompanied by frantic beeping. If something works, we see "+".
739* VillainOfAnotherStory: Project Carthage was essential for the back story on Franz Hopper, but the Lyoko Warriors don't seem to care about them.
740%%* VitriolicBestBuds: Odd and Ulrich. Emphasized most in "Killer Music".
741%%* VocalDissonance: One of the government agents in "False Lead".
742%%* VolcanicVeins: The Kolossus
743* WakeUpGoToSchoolSaveTheWorld: The premise of the series. This is one time where the heroes sometimes ''benefited'' from this trope -- TimeTravel is a good way to make up a missed class.
744%%* WhamEpisode: "Final Round" and, to a lesser extent, "The Key".
745* WhatHappenedToTheMouse: Mister Puck is demoted from the mysterious subject of Aelita's nightmares to a doll in her flashbacks. Perhaps the latter was his intended role all along, but the scenes in which Aelita sees related visions while awake in the episodes "New Order" and "Mister Puck" would suggest otherwise.
746* WhatIsThisThingYouCallLove: Subverted; when Aelita is first materialized she often gets confused by emotions such as embarrassment, and by physical feelings such as being cold. In "Cruel Dilemma", though, Aelita is confused when Jérémie starts blushing when she says, "We can finally be face to face in the same room, touch each-other, and even kiss."
747* WhatTheHellHero: In one episode, Ulrich uses the Return to the Past sequence to help Yumi's parents with finances, buying a lottery ticket after learning the results. When the other members of the team find out, they ''really'' let him have it. (This was ''after'' it has been established that XANA is gaining power as a result of the frequent time hops.) Jérémie suspends him from the team and to add insult to injury, Yumi's folks give the ticket back, claiming it's too expensive a gift for them to accept. (Ulrich manages to redeem himself, and then decides to give the ticket to a charity.)
748* WhatYouAreInTheDark: Yumi and Ulrich, the Queen and King of {{UST}}, each wind up with unrestricted access to the other's diary at one point. Neither one ever considers reading it in order to gain insight into building a desired relationship. Ulrich only opens Yumi's long enough to find out what it is when it got dropped next to him (and even when he sees a photo of himself taped inside, he doesn't in any way use that knowledge against her or so much as theorize as to the implications). Even when Odd suggests it as being a golden opportunity to see what Yumi truly thinks of him, Ulrich instantly shuts it down as morally wrong. Yumi doesn't so much as open Ulrich's since she already knew who it belongs to and simply gave it back to him.
749* WhereTheHellIsSpringfield: Done on a national level. Kadic is ostensibly located in France, given the show's national origin, satellite imagery and the presence of FA-MAS rifles. But we learn in season 2 that it is certainly NOT located in France from an offhand remark about Kadic Academy participating in a foreign exchange program with France.
750* WhyDidItHaveToBeSnakes:
751** Ulrich suffers from [[http://en.wikipedia.org/wiki/Vertigo_(medical) vertigo]] every now and then, and some spots involving him and high places are particularly rocky. It's not that he's afraid of heights, it's that high places are more likely to agitate his condition. He tries his best to suppress this, though.
752** Aelita has a bad thing for wolves. They frequently show up in her dreams or hallucinations.
753* WillTheyOrWontThey: Ulrich and Yumi, to such a ridiculous extent that it makes their own shippers cringe. Though [[spoiler:the last episode hints that they will]]. Eventually.
754%%* WinkDing: Aelita seems to be fond of these.
755* WontGetFooledAgain: In "Opening Act", Yumi briefly gets the upper hand against William by using her telekinesis to alter her fans' trajectory and strike him InTheBack. When she attempts the same strategy again in "Lab Rat", William takes notice and counters by destroying the fans as they approach him from behind.
756* TheWorfEffect: Once at the start of every season:
757** Season 2 begins with Yumi, Odd and Ulrich being soundly defeated by a Tarantula.
758** The first episode of season 3 hints Aelita is on the road to becoming the strongest Lyoko warrior, only for the following one to put her right back into the DamselInDistress role by having the Scyphozoa NoSell her newfound abilities.
759** Finally, season 4 shows Jérémie has upgraded the Lyoko Warriors' arsenal. Xanafied William still wipes the floor with everyone until the Replikas plotline actually begins.
760* WorldInTheSky: The four main sectors of Lyoko are composed of [[FloatingContinent floating islands]] above the Digital Sea. The Mountain Sector, in particular, evokes the most this trope.
761* WorthyOpponent: At the end of "Marabounta", XANA's monsters bow to the Lyoko Warriors after they have to work together to survive.
762* XenomorphXerox: The episode "End of Take" has as MonsterOfTheWeek an animatronic suit possessed by XANA that is a virtual rip-off of the Xenomorph with [[Franchise/{{Predator}} Yautja]]-like head "dreadlock" tentacles (which it uses as ''actual'' CombatTentacles). This look-alikeness is actually lampshaded (although Ulrich can't recall the original film's name) before being told by the director of the InUniverse film (that is using the factory as a film set) to shut up because it is a totally original alien design, honest!
763* XtremeKoolLetterz: The names used for XANA's monsters -- Kankrelat, Blok, Krabe, Kongre, Rekin, Kalamar, Kolossus... Justified in-show by [[{{Keet}} Odd]] coming up with most of these.
764* YourMindMakesItReal:
765** [[JustifiedTrope Justifies]] the phantom pains felt by Yumi, Ulrich, and Odd upon taking damage, since they're non-natives to Lyoko. In one episode, a virus uploaded into the computer by XANA makes it TOO real, with one shot hitting causing immense and dramatic pain.
766** Jérémie has theorized that a person's Lyoko form is reflective of his personality, subconscious desires, and dreams. For example, Yumi's pride in her heritage gave her the appearance of a Geisha, while Ulrich's lionhearted nature gave him the form of a {{Samurai}}.
767* YouWouldntHitAGuyWithGlasses: Played with in "Mister Puck"; Odd tells Herb to take off his glasses as he's about to punch him.
768* ZombieApocalypse: "[[ExactlyWhatItSaysOnTheTin Attack of the Zombies]]" has XANA unleash a zombie plague on the school. Those who are bitten by the possessed Kiwi are transformed into green creatures that wander around aimlessly and infect those they come into contact with.

772* {{Animesque}}: Arguably more so than the actual series; for one thing, a huge SweatDrop appears on Jérémie's head at one point.
773%%* AudienceSurrogate: Odd
774* ChildishPillowFight: Ulrich and Yumi are shown having one in the end credits. Reused throughout Season 1 of the main series.
775* {{Cyberspace}}: Called "Xanadu" here.
776* FacePalm: Ulrich's first reaction to Odd.
777* MindOverMatter: Unlike in the series, Yumi can use her telekinesis in the real world.
778* NewTransferStudent: Odd
779* PragmaticAdaptation: Many changes, like the roommate alignment in ''Garage Kids'' compared to ''Code Lyoko''.
780* StockFootage: The scanner sequences are reused many times in ''Code Lyoko'' Seasons 1-3.
781* {{Tagline}}: ''Ready to save the world! ... Which one?''

792[[/folder]]
793
794[[folder:Tropes in the novel series]]
795* ActuallyIAmHim: In the second book, the Lyoko Warriors explain to Eva Skinner how they defeated XANA for good, [[DramaticIrony unaware that she is possessed]] by a NotQuiteDead XANA. The reader, well aware of this from the start, can practically hear XANA silently laughing at them for their ignorance.
796* AdaptationExpansion: Yes, it can be this and CompressedAdaptation at the same time! The story focuses more on the backstory that was only touched on in the show.
797* AdultsAreUseless: Refreshingly averted. While the adults do nothing at first as in the show, as the story spirals outwards and involves larger organizations, the Lyoko Warriors find themselves turning to several adults for things they can't do themselves. By the end of it, they needed the adults' help to win just as much as the adults needed theirs.
798* AlternateContinuity: PlayedWith. The dates and places of the backstory line up very much with what's in the show; however, the events ''of'' the show, specifically the Warriors' fight against XANA, are very compressed, with William never even joining them.
799* AntiVillain: Dido, and by extension TheMenInBlack. While they oversaw the creation of Project Carthage, [[spoiler:it's created so many problems that now they just want it to go away. They're also trying to stop a group of terrorists from world domination, by whatever means necessary.]]
800* AxCrazy: Eva. Being a pawn of XANA will do that to a person.
801* BigBadDuumvirate: [[spoiler:XANA briefly teams up with the Green Phoenix at the end of the third book. It doesn't last long.]]
802* BigBadEnsemble: Not only is XANA back and plotting to regain the power he lost, the TheMenInBlack are snooping around. [[spoiler:[[BaitAndSwitch It turns out]] the men in black are trying to stop the Green Phoenix organization, a terrorist group trying to take Lyoko's power for themselves. With XANA having a HeelFaceTurn in the fourth book, the Green Phoenix are ultimately left as the true antagonists.]]
803* BreakTheCutie: [[spoiler:In the "Mysterious City" flashback, XANA was a token cutie. Then he got infected with a virus which made him so dangerous, Hopper kept his OnlyFriend Aelita away out of fear. This exacerbated the virus' effect on him, making him lose his memories and leaving him with a void he filled the only way he could--with hate.]]
804* CanonForeigner: About ten of them -- Eva Skinner/XANA, Richard Dupuis, and Grigory Nictapolus, most prominently. Most of them are featured for a chapter, then disappear.
805* ChekhovsGun: While catching a ride from some helpful strangers, Yumi overhears them discussing chemistry and some of the mischief they used it for when they were younger. One mentioned usage? Writing in and unveiling invisible ink, which is useful when they're searching for clues left by Hopper, who taught chemistry at Kadic...
806* {{Cloudcuckoolander}}: Eva comes off as ''strange'' to the cast, as she's perpetually smiling, chipper, and often seems unaware of basic things like food. It's a byproduct of being possessed by XANA, who doesn't have the best grasp of human intricacies and struggles to fake normal behavior.
807* CompressedAdaptation: Only bits of "XANA Awakens", "Code: Earth"[=/=]"False Start", and "Fight to the Finish" still exist in this continuity. Everything else in the show is erased and replaced with the plot that ties those three together, occurring in maybe half the time. The major plots of Seasons 2, 3, and 4 are solved in one battle.
808* DarkerAndEdgier: The books have a more adult tone to them than the show, prominently featuring [[spoiler:a terrorist organization out to dominate the world]], the conspiracies of TheMenInBlack, and children being forced to fight in war. Not against XANA in Lyoko, but actually fight for their lives in the real world. There are also some individual depictions of harsh violence, such as the scene where [[spoiler:Jérémie electrocutes Grigory]], or the flashback of Aelita getting ''shot in the head''.
809* DemonicPossession: Makes its appearance again, courtesy of XANA. Eva especially suffers this for almost all her screentime. [[spoiler:Odd]] too, though not as long as her.
810* DisneyDeath: [[spoiler:XANA pulls a HeroicSacrifice at the end of the fourth book, but the epilogue reveals Aelita was able to recreate and materialize him.]]
811* EvenEvilHasLovedOnes: Grigory Nictapolus may be a PsychoForHire, but he's genuinely fond of his dogs.
812* EvilDetectingDog: Downplayed. Kiwi growls at [[spoiler:XANA-Odd]] when he first sees him, but soon enough starts licking him joyously.
813* ForgottenChildhoodFriend: [[spoiler:XANA and Aelita. When Franz Hopper created XANA, he wanted him to develop emotions, so he encouraged Aelita to visit and play with him in the First City. They ended up becoming best friends. In a twist, they ''both'' got amnesia and forgot about it; remembering his time with her and rekindling their relationship is actually one of the catalysts for XANA's HeelFaceTurn.]]
814* GoMadFromTheRevelation: This is why only children can be virtualized on Lyoko/the First City. One's form there reflects their inner, true self. Because ChildrenAreInnocent, they don't have the same amount of regrets, mistakes, and horrors that adults do. Any adult who enters a virtual world (save Franz, the creator) turns into a monster and [[HeroicBSOD promptly breaks down]].
815* GoryDiscretionShot: Grigory's dogs are the cause of this several times. We don't see them attack Kiwi, but we do see his bloody wounds afterwards. Later, Odd's father sees them with blood on their teeth, and before Grigoy knocks him out, has just enough time to realize the neighbor's dog hasn't barked at all...
816* HeelFaceTurn: [[spoiler: XANA of all people has one.]]
817* HeroicSacrifice: [[spoiler:To prevent TheMenInBlack from taking Hopper's work after the Green Phoenix are defeated, XANA and Jérémie both tell Aelita she needs to enter Code DOWN. She tries to refuse because it'd mean XANA's death; he has to tell her he ''wants'' to for her to agree.]]
818* HoistByHisOwnPetard: Mago assembles a bunch of electronically-controlled flamethrowers on the roof of the factory, to defer any attempts at aerial infiltration. [[spoiler:This bites him in the ass when he forgets about his defenses and tries to make an aerial ''exit'' with his jetpack.]]
819* HumanityIsInfectious: [[spoiler:Turns out, XANA's DemonicPossession works both ways, if he spends enough time in the real world. His possession of Eva gradually introduces human emotions and quirks to him, to his confusion and outrage--and eventual acceptance.]]
820* IHaveYourWife: Anthea was kidnapped as retribution for her and Franz's decision to leave Project Carthage, and videos of her sent to motivate him to return.
821** Later, Mago uses this to force Jérémie to work for him, saying that if he refuses then he will kill Anthea, his girlfriend's mom. Knowing how badly Aelita wants to see her mother again, Jérémie accepts.
822* IShouldWriteABookAboutThis: Albeit at the start instead of the end. The novels are presented as being written and published by Jérémie, with each having a dedication from him.
823* ImaginaryLoveTriangle: Richard, one of Aelita's now-adult classmates, thought he was in one with her when they were kids. He recalls that one day, she made a new friend who she'd talk about non-stop, and the way her eyes sparkled led him to believe her friend was a handsome foreigner who'd swept her off her feet. [[spoiler:Hilariously enough, this friend was ''XANA''.]]
824* InNameOnly: A number of characters and concepts depicted in the novels are very different from their counterparts in the show. The Replikas, for example, are unique offshoot virtual worlds still tied to Lyoko but accessed from other interfaces, rather than copies of Lyoko created by XANA. The Subdigitals, or rather "[[AdaptationNameChange Ceb Digitals]]", have a completely different roster of band members, a logo and motto unique to the books, and a song titled "Luv Luv Punka" that's unlike any of the songs in the show version's soundtrack.
825* InsultBackfire: Sissi, spotting the NewTransferStudent Eva staring blankly at the cafeteria food, saunters up and condescendingly starts explaining what each one is. Eva smiles, says she must be the waitress, and tells her her order, much to Sissi's fury and the Lyoko Warriors' amusement.
826* ItsProbablyNothing: The Lyoko Warriors note a lot of strange incidents of electricity sparking or technology breaking, and sometimes wonder if it's XANA...before dismissing that because he must be dead.
827* LadykillerInLove: Odd genuinely likes Eva, and is quite heartbroken to find out she was possessed by XANA. [[spoiler:Fortunately for him, he and the real Eva still get along great.]]
828* LaserGuidedAmnesia:
829** The memory machine, originally created to assist in the creation of the virtual world, was altered by the men in black [[spoiler:and later stolen by the Green Phoenix]] to inflict this. Instead of copying information from a person's brain, it erases it, right down to the specifics.
830** Hannibal Mago's assistant/servant, Memory, has this, hence her MeaningfulName. [[spoiler:Her original identity is Anthea, Aelita's mother.]]
831* LeakingCanOfEvil: [[spoiler:Project Carthage was locked up, but that didn't stop its power from infecting XANA in the form of a virus.]]
832* LoveAtFirstSight: Odd, with Eva Skinner (who he doesn't know is XANA).
833* TheMenInBlack: Make their return, their attention having been caught by the Lyoko Warriors poking to find information about Franz Hopper.
834* TheMole: [[spoiler:Walter Stern, Ulrich's father]] was this when he worked for Franz Hopper, secretly sending the results of Hopper's research to [[spoiler:the Green Phoenix]]. Later, [[spoiler:he was blackmailed by Dido into doing the same for her, but he was discovered quickly enough that she didn't obtain the supercomputer's location.]]
835* NeuroVault: [[spoiler:Not only does Aelita have the Keys of Lyoko, she has ''Lyoko itself'' copied into her head. She willingly agreed to let her father download it so that if Code DOWN was entered, Lyoko could be restored; the only price was surges of amnesia.]]
836* NewTransferStudent: Eva Skinner is the newest Kadic student, hailing from America (specifically California).
837* NiceJobBreakingItHero:
838** Aelita just wanted to find out more about her dad. Her friends just wanted to help her. Their snooping for Franz Hopper's information just alerted TheMenInBlack to someone sticking their noses where they shouldn't, and brings them down on their heads.
839** Odd [[spoiler:decides not to tell Jérémie about the memory card he found, instead bringing it to Eva. Once XANA finds out what's on the card, he takes the opportunity to possess Odd too.]]
840** Franz Hopper [[spoiler:became afraid of XANA after he was infected by Carthage, and decided to keep Aelita away for her own safety. Without his [[MoralityChain sole friend and voice of reason]], XANA quickly succumbed to the virus and became a monster.]]
841* NoPlansNoPrototypeNoBackup: Averted in general.
842** Hopper was a leading scientist working for a powerful organization; of course he made a ton of detailed notes. He wasn't able to bring all of them with him when he fled, so TheMenInBlack were able to scrap together their own virtual reality equipment from what he left behind.
843** The memory gauntlet had its plans stolen by [[spoiler:Ulrich's father]]. It was presented to and recreated by Dido [[spoiler:and the Green Phoenix]]. The original creator was also able to rebuild it using spare notes.
844** [[spoiler:Not wanting his work to fall into enemy hands but also not wanting it completely destroyed, Hopper (with permission) downloaded ''all of it'' into Aelita's brain, should she ever need to enter Code DOWN. Thus she's able to rebuild everything in the epilogue.]]
845** PlayedWith for XANA. He notes that it's impossible to make a backup of himself [[spoiler:after his HeelFaceTurn; he's too human now. Aelita's still able to bring him back in the epilogue, but only because their childhood past gave her enough memories ''of'' his humanity to work with.]]
846* NonActionGuy: Richard and Jérémie both; Richard because he's a regular guy too old to go to Lyoko, and Jérémie because he's MissionControl. [[spoiler:That said, Jérémie gets a pretty awesome moment where he tries to tackle Grigory in the climax.]]
847* OffscreenBreakup: Implied. Jérémie's dedication is ultimately for Aelita, but he wonders if she's still listening, suggesting they're no longer together.
848-->"This story is for all of my friends, but it is above all else for you, Aelita. Goodness knows if you're still listening..."
849* OrphansPlotTrinket: Aelita's sailor's knot pendant definitely qualifies.
850* PowersAsPrograms: The Lyoko Warriors are only able to be so in Lyoko or the First City. The virtual worlds are literally programmed to reflect one's true self, so if one's self happens to be a LadyOfWar or [[{{Samurai}} noble swordsman]], [[TookALevelInBadass well...cut loose]]. [[spoiler:However, XANA helps them materialize as their avatars in the ''real'' world for the final battle--humorously enough, with an actual equipable item.]]
851* PretendToBeBrainwashed: [[spoiler:After Green Phoenix is defeated, Jérémie convinces Dido to let him and his allies keep their memories when the men in black have been using the [[LaserGuidedAmnesia memory machine]] on everyone else to keep the events under wraps, at least after the protagonists used Code DOWN to erase Lyoko. Giving in, Dido describes the side effects of the memory wipe to Jérémie in detail and advises him and his friends to act in this manner when the clean-up crew arrives.]]
852* RaceAgainstTheClock: Grigory shuts off the supercomputer in the climax of the fourth book. Because of its massive size, Jérémie notes it'll take a few minutes to finish shutting down, but once it does, the battle will be lost before it starts, his friends will be trapped inside, [[spoiler:and XANA will just die since he doesn't have a backup]]. Better cancel the shutdown quickly!
853* TheReveal:
854** XANA spends the first two and a half books being [[HeWhoMustNotBeSeen unseen]], as always, and acting through possession. But eventually, he makes an actual physical appearance. [[spoiler:He's a teenage boy [[IdenticalStranger strongly resembling]] William.]]
855** Particularly savvy readers might put [[{{Foreshadowing}} the clues together]], but [[spoiler:the boy in the prologue of the second novel and Aelita's mysterious childhood friend "Mr. X" are both XANA.]]
856* SealedEvilInACan: [[spoiler:The First City and Lyoko were created as a giant pile of cans inside cans, and at the very heart of the First City, in a castle, is Project Carthage. Unable to destroy it, Hopper instead locked it up so that its massive destructive potential would never see the light of day.]]
857* SelfDestructMechanism: This is Code DOWN's function, a last-resort option. It would completely destroy Lyoko, XANA, the First City, and even the supercomputer if they ran the risk of falling into enemy hands. To stop those enemies from disabling Code DOWN, Hopper had it divided into pieces that only Aelita would be able to find and reassemble.
858* {{Sleepwalking}}: Aelita does this several times without realizing it. Given her memory loss and how she always ends up at plot-important locations, it's likely her subconscious is trying to guide her to places she once knew.
859* SpellMyNameWithAnS: Suzanne Hertz's name is changed to Susan, and Antea's name is written as Anthea (or Anthéa?). Jeremy, Sissi, Herve, and XANA are written in those forms.
860* SuperSmoke: XANA's depicted as sending streams of smoke to or from the people he possesses. He can also do the traditional variant, turning into smoke to move swiftly or teleport.
861* SurprisinglyRealisticOutcome: In the first book, the Lyoko Warriors take a train to follow up on a lead about the Hermitage in another city. When they're done, it's become late, so when they try to take a train back to Kadic they're immediately detained for being minors traveling without an adult at night.
862* TisOnlyABulletInTheBrain: While fleeing TheMenInBlack, [[WouldHurtAChild one of them shot Aelita in the head]]. She survived long enough for her father to get her to the scanners, which healed the wound while virtualizing her.
863* WeaksauceWeakness: XANA materializes an army of robots at one point, which are durable, powerful, and heavily numbered. They're also completely powered by electricity, so Odd stops the entire army just by cutting [[spoiler:Kadic's]] power.
864* WhatTheHellHero:
865** Yumi is ''not'' happy when Ulrich tackles her to the ground to stop her from talking to William.
866** Aelita scolds Jérémie for stealing money from Principal Delmas to pay for their train tickets. Later, she gives him another when [[spoiler:she finds out he hid the truth about finding her mother from her]].
867* WouldHurtAChild: Pretty much all the antagonists, with varying levels of ruthlessness, are willing to hurt the Lyoko Warriors to stop them.
