22This is the character sheet for the many genetic experiments made by [[Characters/LiloAndStitchMajorCharacters Dr. Jumba Jookiba]] (in other words, Stitch and his "cousins") in Disney's ''Franchise/LiloAndStitch'' franchise, most of whom debuted in ''WesternAnimation/LiloAndStitchTheSeries'', with some having debuted in the anime series, ''Anime/{{Stitch}}''.[[note]]''Animation/StitchAndAi'' introduces new experiments made within the events of that series but doesn't feature any of the classic experiments besides Stitch himself.[[/note]] The numbers of the experiments are almost exclusively pronounced as individual digits (e.g. Stitch is "Experiment Six-Two-Six", not "Experiment Six Hundred Twenty-Six").

42%%NOTES REGARDING THE ABOVE: Jam and Spats were originally listed as being voiced by Grey [=DeLisle=], but an IP user changed their voice actor to Welker. Welker was listed on the Wikipedia article for Leroy & Stitch as the voice of Slugger, but there is a citation needed. The same article lists Strong as the voice of Babyfier, but this was not reflected on the deleted experiment list over there. Bugby was listed on Wikipedia as being voiced by [=DeLisle=].

64The assorted experiments created by Jumba Jookiba were scattered across the island as a result of ''[[WesternAnimation/LiloAndStitchTheSeries The Series]]''[='=] [[WesternAnimation/StitchTheMovie pilot movie]]. Lilo and Stitch made it their mission to seek out all of them and reform them for good.\
65
66As of 2019, 125 of Jumba's experiments (not including the Chinese ones he made in ''Animation/StitchAndAi'', nor the 700 series that exclusively appeared in ''VideoGame/StitchExperiment626'' for [=PlayStation=] 2) have appeared in official media with their names, numbers, and abilities confirmed. Along with Stitch (X-626), this includes Chopsuey (X-621) from ''Stitch: Experiment 626'', seven experiments introduced in ''WesternAnimation/StitchTheMovie'', 91 experiments introduced in ''WesternAnimation/LiloAndStitchTheSeries'',[[note]]44 in season one (including the unnamed Experiment 627) and 47 in season two[[/note]] Coco (X-052) from ''ComicStrip/ComicZoneLiloAndStitch'',[[note]]The comics also had Slobber (X-347) and Hisee (X-531), but they appeared only in the [[CanonMarchesOn decan]][[CanonDiscontinuity onized]] prequel comics well before they would be given names, and their functions were never revealed. Thus, they don't count toward this number. There's also Tippy, who does not have an official number and is really more of a very high-tech doll whose canonicity is disputable (Jumba might have called her an "Experiment" out of force of habit, but then again, he is known to be a BadLiar), so she doesn't count either. Not only that, only Coco was [[WordOfGod confirmed by]] Creator/JessWinfield.[[/note]] thirteen experiments introduced in ''WesternAnimation/LeroyAndStitch'',[[note]]including Leroy, who was officially designated X-629 in a ''VideoGame/DisneyTsumTsum'' side story of the spin-off manga ''Manga/StitchAndTheSamurai''[[/note]] and eleven experiments introduced in the ''Anime/{{Stitch}}'' anime.[[note]]This includes Cyber (X-000), who does not appear in the experiments list in ''Leroy & Stitch'' and is a completely unique addition added in by the anime's production staff, but does not include Skunkuna (who was made by Dr. Hämsterviel instead of Jumba, at least according to the English dub [[WordOfGod and]] Creator/JessWinfield), the Sproutlings (X-509-A, who are the offspring of X-509/Sprout), and Dark End (who was created by the antagonist of the anime's third season, Delia).[[/note]]
67----
68* TheAce: [[ExactlyWhatItSaysOnTheTin Ace]] (262); 627 is an evil version.
69* AcrophobicBird: Well, "Acrophobic Alien ''Pteranodon''". Slugger (608) is only ever seen flying once or twice in ''The Series'', though the anime ''Stitch!'' shows him flying a little more often.
70* AHeadAtEachEnd: Swapper (355).
71* AliensSpeakingEnglish: The experiments known to speak English fluently or proficiently (that have officially appeared in any ''Lilo & Stitch'' media) are Gigi (007),[[note]]As she spoke in ''Leroy & Stitch''[[/note]] Slick (020), Hertz Donut (022),[[note]]Only appeared in the ''Anime/{{Stitch}}'' anime[[/note]] Forehead (044), Squeak (110), Bragg/Flute (145),[[note]]Only appeared in the ''Stitch!'' anime as well[[/note]] Bonnie (149), Clyde (150), Nosy (199), Ace (262),[[note]]Only in the anime's English dub[[/note]] Wormhole (272),[[note]]Also only appeared in the anime[[/note]] Remmy (276),[[note]]Also only in the anime's English dub[[/note]] Spooky (300),[[note]]Mainly provided he replicates someone else as part of a fear, such as appearing as Cobra Bubbles to Nani[[/note]] Heckler (322), Elastico (345),[[note]]Implied in his debut in ''The Series'' as he responds to and says "cousin"; confirmed in the anime[[/note]] Manners (358), Phantasmo (375),[[note]]Based on his possession of the [[SuckECheeses Macki Macaw]] animatronic[[/note]] Chopsuey (621),[[note]]Only appeared in the ''VideoGame/StitchExperiment626'' video game[[/note]] Angel (624),[[note]]However, she does not speak English in ''The Series'' or ''VideoGame/DisneyMagicKingdoms''[[/note]] Reuben (625), [[Characters/LiloAndStitchTheTitularDuo Stitch (626)]], 627,[[note]]Only in the anime, since in his original appearance, all he could say was "evil"[[/note]] and Leroy (629). In addition, Frenchfry (062) can speak fluent [[GratuitousFrench French]] while Carmen (123)--in the anime, at least--can speak fluent [[GratuitousSpanish Spanish]] (even though [[Creator/CarmenMiranda her namesake]] spoke Portuguese).
72* AllThereInTheManual: Averted; the credits for ''WesternAnimation/LeroyAndStitch'' lists the names of '''all of them''', [[SeriesContinuityError although they made some mistakes in that list]]. Granted, a good deal of them don’t appear and all we have to go by is their name.
73* AmbiguousRobots: Tippy, an experiment from ''ComicStrip/ComicZoneLiloAndStitch'' without any official number, seems to be this.
74* AnimateInanimateObject: Caused by Phantasmo (375) when he possesses any non-living thing. Nosox (204) also bears a strong resemblance to a washing machine, but is clearly a living creature, as is Stopgo (102), who resembles a stoplight.
75** LivingToys: At one point, he possesses Lilo's doll, Scrump.
76** HauntedTechnology: As a benevolent example of this trope, his episode ends with him possessing a restaurant's broken animatronic and finding his one true place entertaining customers.
77* AttackReflector: Slugger (608), who's designed to deflect projectiles with his tail.
78* ArtificialFamilyMember: OK, ''[[FamilyOfChoice extended]]'' family members, but all of them count towards this.[[note]]Although Stitch, being a title protagonist, gets this trope applied to him more than all the others.[[/note]] Jumba initially just created them to do various, usually "evil" tasks, but over the course of the franchise (mainly the films and first TV series), they all become "cousins" to one another as they join the Pelekai ''ʻohana''.
79* BadassFamily: Considering that they are a family of "cousins" who all happen to be illegal genetic creations with unique powers. ''Leroy & Stitch'', as well as a few episodes of ''The Series'' and the anime, show how badass they are when they work together towards a common goal.
80* BatmanCanBreatheInSpace: ''The Series'' episode "The Asteroid" shows that the experiments can survive the vacuum of space.
81* BarbershopQuartetsAreFunny: Experiment 044 (Forehead) is designed to annoy people with his off-key barbershop quartet singing.
82* BigDamnHeroes: Several of the experiments get these after they are turned good. Sparky gets several in ''Stitch! The Movie''.
83* BioweaponBeast: Many experiments were bio-engineered for the purpose of combat, most notably the 6-Series.
84* CanonForeigner: The experiments from ''ComicStrip/ComicZoneLiloAndStitch''. The only officially canonized one is Coco (052), and the other ones with known names and/or numbers are Slobber (347), Hisee (531), and [[AmbiguousRobots Tippy]].
85* ChainedHeat: Link (251), who binds two or more incompatible people together with his goop, which dissolves in Earth mud.
86* CountingSheep: Drowsy (360) is a reference to this trope, being a sheep-like experiment who is designed to put people into a deep sleep by bleating.
87* CloneDegeneration: Dupe (344), whose ability divides the target's power between them and their clones.
88* CripplingOverspecialization: A common weakness for Stitch's cousins; they're usually made for one purpose and one purpose only, making it impossible for them to put their talents to use for anything else. For example, Slugger (608) can play baseball because of his power to deflect incoming projectiles. However, he cannot play basketball for the exact same reason.
89* {{Cyborg}}: Cyber (000), who actually debuted in the ''Stitch!'' anime, thus leaving his status in the canon dubious. He didn't start out like this, but after Jumba ditched him due to his violent psychological instability, he somehow acquired a cybernetic eye with a drill for an ear, replaced his arms for cybernetic ones with different weapons for each, and replaced his two legs with three-bladed spider-like legs.
90* DeathRay: Heat (609), who can shoot a heat ray from his forehead.
91* DigitizedHacker: Glitch (223), who is designed to possess electrical equipment and turn them against their owners.
92* DrillMole: Digger (529), who looks more like a meerkat than a mole.
93* EarlyInstallmentWeirdness: InUniverse example: Shrink (001) was apparently named by either Jumba or Hämsterviel well before the events of the franchise, as shown by a newspaper with the headline, "Idiot Scientist Actually Creates Something!"
94* ElementalPowers: Most of the 5-Series and a couple from the other series as well.
95** AnIcePerson: Slushy (523), who can cause snowstorms in places by blowing ice at the highest peak.
96** BlowYouAway: Blowhard (533) and Phoon (540). The former's designed to immobilize people by blowing them like kites while the latter's designed to cause windstorms.
97** DishingOutDirt: Richter (513), who causes earthquakes by slapping his tail on the ground.
98** GreenThumb: Sprout (509), which is a plantlike experiment.
99** MagmaMan: Yang (502), who can shoot lava from his humps.
100** MakingASplash: Yin (501) and Cannonball (520). The former is designed to spray water, though she needs to get it from outside sources, while the latter causes tsunamis when he splashes into any body of water.
101** MetalMuncher: Tank (586), who grows bigger with every piece of metal he eats.
102** PlayingWithFire: Splodyhead (619) and Melty (228). While both of them shoot/breathe fire, the latter is designed to melt non-organic material with it.
103** ShockAndAwe: Sparky (221), who can cause blackouts by overloading power sources with his electricity.
104* EnergyWeapon: Zap (603), who is a ''living laser beam''.
105* EpicFlail: Thresher (544), who can flail his tentacles around to destroy things.
106* {{Expy}}:
107** Babyfier is a fairy version of [[Franchise/{{Pokemon}} Mew]] with a baby theme and the cuteness turned up a notch, down to sharing the index number 151. Even its whole concept draws a parallel with Mew's representation of an animal fetus.
108** Also Spike (319), who looks almost exactly like [[Franchise/{{Digimon}} Togemogumon]].
109* {{Fictionary}}: The experiments' native language is called Tantalog, which is supposedly a cross between native Hawaiian, Chinese, and "Chezcreekian", the last one supposedly being an obscure language spoken by a minority of people in the rural parts of Chesterfield in North Derbyshire, England. That said, some of the phrases in Tantalog (at least based on fan-made dictionaries) seem to take inspiration from other languages including French, Arabic, and Hebrew, and are incongruent with some of the Tantalog spoken in the official media (which make liberal use of "ah" and "ee" sounds). (In actuality, Tantalog was ''The Series''[='=]s creators' attempt to turn Stitch's gibberish into a somewhat consistent language.)
110* {{Flat Character}}s: An overwhelming majority of the experiments, sadly. Some of them do get some semblances of a personality, but they're not fleshed out enough.
111* ForcedSleep: Experiment 360 (Drowsy) is designed to make people fall into eternal sleep by just bleating at them.
112* {{Foreshadowing}}: Their existence was first implied by [[BadLiar Jumba lying]] to the United Galactic Federation all the way back in the prologue of the original film itself.
113* FreakyFridayFlip: Swapper (355), who can do this to two or more people by staring at them, and only he can switch them back.
114* TheGhost: Even though Jumba made over 600 experiments, we only see 125 of them[[note]]with confirmed names, numbers, and functions; this number does not include the Chinese experiments in ''Stitch & Ai''[[/note]] throughout all the films, the first two shows, and a few spin-off media; the rest of Stitch's "cousins" remain unseen to this day.
115* GiantEnemyCrab: Shortstuff (297), although it's due to a growth ray.
116* GoneHorriblyRight: In the ''Stitch!'' anime, Jumba designed Experiment Zero, also known as Cyber, to be the ultimate killer monster, and he succeeded--a little too well, in fact, because the experiment proved impossible to control. Thus, Jumba was forced to imprison him on an icy planet far away.
117* GoneHorriblyWrong: A few of the experiments' destructive qualities weren't intentional, but instead a result of something going wrong with their powers--Skip for example was meant to be a MundaneUtility to help Jumba reheat his leftovers by making time skip ahead ten minutes. Somehow, Skip ended up making ten ''years'' go by instead.
118* GottaCatchEmAll: Their role in ''The Series'' is for Lilo and Stitch to find them, rehabilitate them, name them, and give them a purpose beyond evil or mischievous intents.
119* HiddenDepths: Even though this is not a musical franchise, a lot of experiments seem to have some form of musical talent, most of which were seen during the impromptu "Aloha ʻOe" concert in ''Leroy & Stitch'':
120** Three of Forehead (044)'s heads can sing well. If his fourth head could also sing, then he would be a one-experiment barbershop quartet.
121** Carmen (123) is a natural player of the maracas.
122** PJ (133) can play the trumpet. The end of ''Stitch and the Planet of Sand'' shows that Squeak (110), Ace (262), and Nosy (199) can also play the trumpet.
123** Bragg/Flute (145) is a very talented flutist and harmonica player.
124** Sample (258) is excellent at maintaining rhythm by providing backbeats from the [[MeaningfulName samples of sound]] he records, which makes him perfect for the band he's in.
125** Elastico (345) can play the trombone.
126** Swapper (355) can play the keyboard.
127** Sprout (509) can play the drums.
128** Richter (513), Kixx (601), and a green experiment believed to be Choppers (441) can play the bongos, with the first and third of them being able to play the instrument with their tails.
129** Thresher (544) can play the marimba.
130** Although Yaarp (613) does not play an instrument, he is able to perform with the horn on his head.
131** Finally, all three of the main trio of experiments are highly capable musicians: Angel (624) has her natural singing ability, Reuben (625) can play the saxophone, and Stitch (626) is known for his guitar and ukulele talents.
132* HonestJohnsDealership: Slick (020), whose main function is to talk people into buying things.
133* HollywoodToneDeaf: Forehead (044). Just read this quote below.
134-->'''Forehead's first three heads:''' We're evil 'cause we sing...!\
135'''Forehead's fourth head:''' ANNOYINGLY OFF-''KEEEY''!\
136'''Stitch:''' ''(pulling down his ears)'' ''Sheesh!''
137* HoistByHisOwnPetard: Snafu (120) whose main function is to sabotage enemy plans. This makes him frustratingly difficult to capture, with Jumba stating that the only way to do so is by ''accident''.
138* InconsistentSpelling: More like Inconsistent ''Numbering'' here:
139** Bonnie and Clyde are arguably the worst off in this; in [[Recap/LiloAndStitchTheSeriesS1E36BonnieAndClyde their debut episode]] (first aired in 2004), their one episode in the anime (first aired in 2010), and even [[https://archive.org/details/japanese-stitch-characters-encyclopedia a Japanese characters encyclopedia,]] they were numbered 349 and 350, respectively. But ''WesternAnimation/LeroyAndStitch'' (2006)[='=]s experiments list in its end credits respectively numbered them as 149 and 150, which--in the absence of definitive English-language confirmation by Disney--have become the accepted numbers for them by the franchise's fanbase.
140** Finder has it nearly as bad; he was numbered 458 in [[Recap/LiloAndStitchTheSeriesS1E26Finder his debut episode]], which would have made him the only 4-Series experiment to be the experiment of focus for an episode. The Japanese encyclopedia also uses 458 for him. However, "Skip" and ''Leroy & Stitch'' both number him as 158, negating the 4-Series from having a major representative experiment.
141* InstantMassJustAddWater: Experiments deactivated into pod form are reactivated by coming in contact with water.
142* InstantPeopleJustAddWater: Likewise, especially since they are sapient beings.
143* InvoluntaryDance: Carmen (123) and the anime version of Sample (258).
144* LazyBum: Lax (285)'s main function is to turn people (and machines) into this. His powers don't work on [[WesternAnimation/{{Recess}} Gretchen]], however, as she considers work to be relaxing.
145* LegoGenetics: All of the experiments were genetically engineered by Jumba, who took the DNA of several alien creatures and put them together to create super-powerful creatures of chaos, destruction, and mischief. Some of the creatures used to make Stitch in particular were shown in ''WesternAnimation/TheOriginOfStitch'' short film.
146* LiteralGenie: Wishy-Washy (267) grants wishes literally, but only as long as he still has power left as indicated on his belly marking.
147* {{Living MacGuffin}}s: They are the primary focus of ''Lilo & Stitch: The Series'', where the titular duo has to hunt them down and make them good.
148* {{Living Prop}}s: Reformed experiments seen in ''The Series'' are usually just there to support the main ''ʻohana'' for various means. This goes double for some like Backhoe (040), whom we only ever see in this context, with no information on how they were previously caught and tamed.
149* LovePotion: Hunkahunka (323), though his ability's more akin to [[LoveAtFirstSight Cupid's Arrow]].
150* {{MacGuffin}}s: Especially as pods.
151* MakeAWish: Wishy-Washy (267), although he grants wishes ''very'' literally.
152* MeaningfulName: Every single experiment is named after their primary function.
153* MesACrowd: Dupe (344), though [[ConservationOfNinjutsu the strength among the clones he makes is divided among them.]]
154* MonsterOfTheWeek: In ''The Series'', each episode focuses on tracking down and dealing with a new and unique member of this lot. The anime also has this trope but to a lesser degree and mainly during its second and third seasons.
155* MonstrousGerms: Poxy (222) is an amoeba with limbs and a face that infects people’s bodies to give them humiliating illnesses, such as smelly feet, purple pimples, and uncontrollable burping.
156* MuckMonster: Ploot (505) is a variation, he's not an actual blob of pollution, but he instead absorbs trash to grow larger and can flood cities by transforming his collected garbage into black sludge. There’s also Fudgy (054), who's made of chocolate.
157* MundaneUtility: Lilo tries to find a place where an experiment can use its ability for good. In fact, the 0-Series was created for testing and/or household purposes, though some of them [[GoneHorriblyRight went horribly right]]; Frenchfry (062) for example, was meant to be Jumba's personal chef. The thing ended up [[spoiler:trying to eat ''him'']].
158* NightmareWeaver: Remmy (276) is designed to give people nightmares and trap them inside them if they wake up while he's still in their minds.
159* NoNameGiven:
160** 627 and 628; the former was because he could not be rehabilitated and the latter was because it was never activated, so Lilo and Stitch never dealt with it.
161** Leroy was an [[InvertedTrope inversion]] in his debut appearance by having a name but not a number. This ended in June 2020 when a ''Manga/StitchAndTheSamurai'' side story established him as being Experiment 629.
162* NonMaliciousMonster: Some experiments seem to be less "evil" and more acting on their primary functions. Indeed, some of them are friendly from the get-go, with the only obstacle to their reformation being that their functions are meant for evil purposes. Others are so non-malicious that they find their "one true place" all on their own (Elastico and Gigi being good examples).
163* OlympusMons: The NighInvulnerable 627, the apocalypse-inducing 611, and Stitch himself. The 6-series is generally created with this trope in mind.
164* OurDragonsAreDifferent: Melty (228).
165* PersonOfMassDestruction: El Fin (611). His primary function is to be the ultimate super weapon.
166* {{Planimal}}: Stamen (103), whose ears are shaped like flowers that distract bees from pollinating real ones.
167* PlantAliens: Sprout (509).
168* PokemonSpeak: Gotchu (031), Woops (600), and--in the anime--Checkers (029); Felix (010) and 627 are actually just OneWordVocabulary, since the only words they could say ("Dirty!" and "Evil!", respectively) are not their names.[[note]]However, Felix did say a couple other words in the anime episode "Stitch vs. Hämsterviel, Pt. I", and 627's vocabulary was expanded in his anime episode.[[/note]]
169* PrehistoricAnimalAnalogue: Some of the experiments have traits of dinosaurs; Richter (513) resembles an ''Ankylosaurus'' and Slugger (608) resembles a ''Pteranodon'', for example.
170* PsychoPrototype: Cyber (000) from the ''Stitch!'' anime is this to, well, Stitch, as the first experiment Jumba created and designed to essentially be a living weapon, not dissimilar to Stitch's original purpose of destroying everything he touches. He even had all of Stitch's powers in his original form. However, Jumba was unable to control Cyber and had to imprison him.
171* RealityWarper: Shoe (113) controls luck, and Launch (607) is said to be able to warp the fabric of time and space, eventually causing the entire universe to collapse upon itself.
172* RidiculouslyCuteCritter: Several experiments qualify as this; Mr. Stenchy (254), in particular, was specifically ''[[InvokedTrope designed]]'' to be this so he can draw people in with his cuteness before releasing his stench.
173* RubberMan: Elastico (345) can stretch his limbs and contort himself as if he doesn't have bones.
174* SailorEarth:
175** Because of the massive number of experiments that have not appeared, there are lots of fanfics about Lilo and Stitch capturing fan-made experiments. Even then, some fans like to make new experiments that are numbered after Stitch, 627, and Leroy.
176** Interestingly, they were invoking this trope long before the series was even around. Even in the immediate aftermath of the first movie, the implication of 625 then-off-screen experiments meant 625 blank character slates and 625 stories to be told. Fanfic writers eagerly took up the challenge.
177* ScaryScorpions: Plasmoid (617) resembles one, and he can shoot plasma balls from his tail.
178* SecretProjectRefugeeFamily: All of them were created in a lab by a mad scientist for destructive purposes, and are now (mostly) stranded on Earth. They don't all live under the same roof, but Stitch considers them all to be his ''ʻohana''.
179* SequelNonEntity: Not a single experiment from the first two shows' continuities appear in ''Animation/StitchAndAi''.
180* ShrinkRay: Shrink (001) is designed to, well, shrink things, although he can also enlarge things.
181* ShoutOut: Some of the experiments' names, numbers, designs, and/or functions:
182** Topper's number (025) is a reference to the date of Christmas Day (December 25).
183** Carmen (123) is based on and named after Creator/CarmenMiranda.
184** Hunkahunka (323) is named after a line in "Burning Love" by Lilo's idol Music/ElvisPresley.
185** Experiment 452 (who never appeared in any work) is named [[WesternAnimation/ReBoot Bob]].
186** Houdini (604) is obviously named after [[Creator/HarryHoudini the famous escape artist]].
187* SingleSpecimenSpecies: Every single experiment (sans Leroy and his clones if cloning counts) is each the only member of their species (the numbers being their "species names"), which is also partially why they're "cousins" and ''not'' siblings.
188** There are a few "exceptions" (loosely speaking) to this rule, specifically the Stitch-type experiments:
189*** Stitch/626 (the original, ultimate, and successful culmination of Jumba's research and experimentation).
190*** The FlawedPrototype versions of Stitch: Cyber/000 (Jumba's original BioweaponBeast LivingWeapon that [[GoneHorriblyRight Went Horribly Right]]), Woops/600 (all of Stitch's genetics and powers, but is afflicted with abhorrent klutziness), Chopsuey/621 (all of Stitch's genetics and powers, but not as skilled or competent), and Reuben/625 (all of Stitch's genetics and powers, plus better language capability, but also lazy, cowardly, and gluttonous).
191*** The EvilCounterpart versions of Stitch: 627 (SuperiorSuccessor to Stitch with many more powers and completely evil) and Leroy/629 (a straight-up EvilTwin clone of Stitch)
192*** Others who are similar to Stitch physically, mentally, and powerwise, particularly among the 6-series: Sparky/221 (similar body type with an extra set of retractable arms), Kixx/601 (similar four-armed body), Yaarp/613 (similar four-armed body), Splodyhead/619 (similar body type, four legs instead of arms), and Angel/624 (a DistaffCounterpart of Stitch's line).
193* ToiletHumor: The name of the unseen Experiment 444, Pooperson.
194* TheTransmogrifier: Morpholomew (316) can transform targets into other living organisms as long as he has photographic memory of the form he's transforming them into.
195* {{Tuckerization}}: Jesstifer (354), named after ''The Series'' writer and executive producer Creator/JessWinfield, who previously used the name as his online identity, particularly on TV Tome.
196* TurnedAgainstTheirMasters: Implied with Felix and Frenchfry, who were originally supposed to be Jumba's personal cleaner and chef respectively, but due to errors in their programming, ended up trying to kill him.
197* VoiceChangeling: Spooky (300) changes his voice whenever he transforms.
198* WhatHappenedToTheMouse: [[spoiler:628's Experiment Pod]], though WordOfGod admitted that [[spoiler:that wasn't meant to be a SequelHook; it was just meant as a joke]].
199* YouAreNumberSix: Technically all of them to Jumba, which plays a role in why Lilo went on to name them all. 627 and 628 were never named, however; the former due to being made to be impossible to rehabilitate, and the latter due to neither Lilo nor Stitch having ever dealt with it.
