Go To
You thought your pets were hard to take care of? Look what Lilo has to deal with!

This is the character sheet for the many genetic experiments made by Dr. Jumba Jookiba (in other words, Stitch and his "cousins") in Disney's Lilo & Stitch franchise, most of whom debuted in Lilo & Stitch: The Series, with some having debuted in the anime series, Stitch!.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").

The assorted experiments created by Jumba Jookiba were scattered across the island as a result of The Series' pilot movie. Lilo and Stitch made it their mission to seek out all of them and reform them for good.

As of 2019, 125 of Jumba's experiments (not including the Chinese ones he made in Stitch & Ai, nor the 700 series that exclusively appeared in Stitch: Experiment 626 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 Stitch! The Movie, 91 experiments introduced in Lilo & Stitch: The Series,note  Coco (X-052) from Comic Zone: Lilo & Stitch,note  thirteen experiments introduced in Leroy & Stitch,note  and eleven experiments introduced in the Stitch! anime.note 

  • The Ace: Ace (262), 627 is an evil version.
  • Acrophobic Bird: 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.
  • A Head at Each End: Swapper (355).
  • Aliens Speaking English: The experiments known to speak English fluently or proficiently (that have officially appeared in any Lilo & Stitch media) are Gigi (007),note  Slick (020), Hertz Donut (022),note  Forehead (044), Squeak (110), Bragg/Flute (145),note  Bonnie (149), Clyde (150), Nosy (199), Ace (262),note  Wormhole (272),note  Remmy (276),note  Spooky (300),note  Heckler (322), Elastico (345),note  Manners (358), Phantasmo (375),note  Chopsuey (621),note  Angel (624),note  Reuben (625), Stitch (626), 627,note  and Leroy (629). In addition, Frenchfry (062) can speak fluent French while Carmen (123)—in the anime, at least—can speak fluent Spanish (even though her namesake spoke Portuguese).
  • All There in the Manual: Averted; the credits for Leroy & Stitch lists the names of all of them, 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.
  • Ambiguous Robots: Tippy, an experiment from Comic Zone: Lilo & Stitch without any official number, seems to be this.
  • Animate Inanimate Object: 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.
    • Living Toys: At one point, he possesses Lilo's doll, Scrump.
    • Haunted Technology: 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.
  • Attack Reflector: Slugger (608), who's designed to deflect projectiles with his tail.
  • Badass Family: 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.
  • Batman Can Breathe in Space: The Series episode "The Asteroid" shows that the experiments can survive the vacuum of space.
  • Barbershop Quartets Are Funny: Experiment 044 (Forehead) is designed to annoy people with his off-key barbershop quartet singing.
  • Big Damn Heroes: Several of the experiments get these after they are turned good. Sparky gets several in Stitch! The Movie.
  • Bioweapon Beast: Many experiments were bio-engineered for the purpose of combat, most notably the 6-Series.
  • Canon Foreigner: The experiments from Comic Zone: Lilo & Stitch. The only officially canonized one is Coco (052), and the other ones with known names and/or numbers are Slobber (347), Hisee (531), and Tippy.
  • Chained Heat: Link (251), who binds two or more incompatible people together with his goop, which dissolves in Earth mud.
  • Counting Sheep: 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.
  • Clone Degeneration: Dupe (344).
  • Crippling Overspecialization: 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.
  • Cyborg: Cyber (000), who actually debuted in the Stitch! anime, thus leaving his status in the canon dubious.
  • Death Ray: Heat (609), who can shoot a heat ray from his forehead.
  • Digitized Hacker: Glitch (223), who's designed to possess electrical equipment and turn them against their owners.
  • Drill Mole: Digger (529), who looks more like a meerkat than a mole.
  • Early-Installment Weirdness: In-Universe 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!"
  • Elemental Powers: Most of the 5-Series and a couple from the other series as well.
    • An Ice Person: Slushy (523), who can cause snowstorms in places by blowing ice at the highest peak.
    • Blow You Away: 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.
    • Dishing Out Dirt: Richter (513), who causes earthquakes by slapping his tail on the ground.
    • Green Thumb: Sprout (509), which is a plantlike experiment.
    • Magma Man: Yang (502), who can shoot lava from his humps.
    • Making a Splash: Yin (501) and Cannonball (520). The former's 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.
    • Metal Muncher: Tank (586), who grows bigger with every piece of metal he eats.
    • Playing with Fire: Splodyhead (619) and Melty (228). While both of them shoot/breathe fire, the latter's designed to melt metal with it.
    • Shock and Awe: Sparky (221), who can cause blackouts by overloading power sources with his electricity.
  • Energy Weapon: Zap (603), who is a living laser beam.
  • Epic Flail: Thresher (544), who can flail his tentacles around to destroy things.
  • Expy:
    • Babyfier is a fairy version of 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.
    • Also Spike (319), who looks almost exactly like Togemogumon.
  • 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.)
  • Flat Characters: An overwhelming majority of the experiments, sadly. Some of them do get some semblances of a personality, but they're not fleshed out enough.
  • Forced Sleep: Experiment 360 (Drowsy) is designed to make people fall into an eternal sleep by just bleating at them.
  • Foreshadowing: Their existence was first implied by Jumba lying to the United Galactic Federation all the way back in the prologue of the original film itself.
  • "Freaky Friday" Flip: Swapper (355), who can do this to two or more people by staring at them, and only he can switch them back.
  • The Ghost: Even though Jumba made over 600 experiments, we only see 125 of themnote  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.
  • Giant Enemy Crab: Shortstuff (297), although it's due to a growth ray.
  • Gone Horribly Right: In the Stitch! anime, Jumba designed Experiment Zero, AKA 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.
  • Gone Horribly Wrong: 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 Mundane Utility to help Jumba reheat his leftovers by making time skip ahead ten minutes. Somehow, Skip ended up making ten years go by instead.
  • Gotta Catch 'Em All: 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.
  • Hidden Depths: 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:
    • 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.
    • Carmen (123) is a natural player of the maracas.
    • 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.
    • Bragg/Flute (145) is a very talented flutist and harmonica player.
    • Sample (258) is excellent at maintaining rhythm by providing backbeats from the samples of sound he records, which makes him perfect for the band he's in.
    • Elastico (345) can play the trombone.
    • Swapper (355) can play the keyboard.
    • Sprout (509) can play the drums.
    • 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.
    • Thresher (544) can play the marimba.
    • Although Yaarp (613) does not play an instrument, he is able to perform with the horn on his head.
    • Finally and most obviously, all three of the mid six-twos 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.
  • Honest John's Dealership: Slick (020), whose main function is to talk people into buying things.
  • Hollywood Tone-Deaf: Forehead (044). Just read this quote below.
    Forehead's first three heads: We're evil 'cause we sing...!
    Forehead's fourth head: ANNOYINGLY OFF-KEEEY!
    Stitch: (pulling down his ears) Sheesh!
  • Hoist by His Own Petard: 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.
  • Inconsistent Spelling: More like Inconsistent Numbering here:
    • Bonnie and Clyde are arguably the worst off in this; in their debut episode (first aired in 2004), their one episode in the anime (first aired in 2010), and even a Japanese characters encyclopedia, they were numbered 349 and 350, respectively. But Leroy & Stitch (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.
    • Finder has it nearly as bad; he was numbered 458 in 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.
  • Instant Mass: Just Add Water!: Experiments deactivated into pod form are reactivated by coming in contact with water.
  • Instant People: Just Add Water!: Likewise, especially since they are sapient beings.
  • Involuntary Dance: Carmen (123) and the anime version of Sample (258).
  • Lazy Bum: Lax (285)'s main function is to turn people (and machines) into this. His powers don't work on Gretchen, however, as she considers work to be relaxing.
  • LEGO Genetics: 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 The Origin of Stitch short film.
  • Literal Genie: Wishy-Washy (267) grants wishes literally, but only as long as he still has power left as indicated on his belly marking.
  • Living MacGuffins: They are the primary focus of Lilo & Stitch: The Series, where the titular duo has to hunt them down and make them good.
  • Living Props: 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.
  • Love Potion: Hunkahunka (323), though his ability's more akin to Cupid's Arrow.
  • MacGuffins: Especially as pods.
  • Make a Wish: Wishy-Washy (267), although he grants wishes very literally.
  • Meaningful Name: Every single experiment is named after their primary function.
  • Me's a Crowd: Dupe (344), though the strength among the clones he makes is divided among them.
  • Monster of the Week: In The Series, each episode focuses on tracking down and dealing with a new and unique member of this lot.
  • Monstrous Germs: 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.
  • Muck Monster: 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.
  • Mundane Utility: 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 went horribly right; Frenchfry (062) for example, was meant to be Jumba's personal chef. The thing ended up trying to eat him.
  • Nightmare Weaver: Remmy (276) is designed to give people nightmares and trap them inside them if they wake up while he's still in their minds.
  • No Name Given:
    • 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.
    • Leroy was an inversion in his debut appearance by having a name but not a number. This ended in June 2020 when a Stitch & the Samurai side story established him as being Experiment 629.
  • Non-Malicious Monster: Some of the 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).
  • Olympus Mons: The Nigh-Invulnerable 627, the apocalypse-inducing 611, and Stitch himself. The 6-series is generally created with this trope in mind.
  • Our Dragons Are Different: Melty (228).
  • Person of Mass Destruction: El Fin (611). His primary function is to be the ultimate super weapon.
  • Planimal: Stamen (103), whose ears are shaped like flowers that distract bees from pollinating real ones.
  • Plant Aliens: Sprout (509).
  • Pokémon Speak: Gotchu (031), Woops (600), and—in the anime—Checkers (029); Felix (010) and 627 are actually just One-Word Vocabulary, since the only words they could say ("Dirty!" and "Evil!", respectively) are not their names.note 
  • Prehistoric Animal Analogue: Some of the experiments have traits of dinosaurs; Richter (513) resembles an Ankylosaurus and Slugger (608) resembles a Pteranodon, for example.
  • Psycho Prototype: 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.
  • Reality Warper: 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.
  • Ridiculously Cute Critter: Several experiments qualify as this; Mr. Stenchy (254), in particular, was specifically designed to be this so he can draw people in with his cuteness before releasing his stench.
  • Rubber Man: Elastico (345) can stretch his limbs and contort himself as if he doesn't have bones.
  • Sailor Earth:
    • Because of the massive numbers of experiments that have not appeared, there are lots of fanfics about Lilo and Stitch capturing fan-made experiments. Even then, some fans also like to make new experiments that are numbered after Stitch, 627, and Leroy.
    • 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.
  • Scary Scorpions: Plasmoid (617) resembles one, and he can shoot plasma balls from his tail.
  • Secret Project Refugee Family: 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.
  • Sequel Non-Entity: Not a single experiment from the first two shows' continuities appear in Stitch & Ai. That's right. None.
  • Shrink Ray: Shrink (001) is designed to, well, shrink things, although he can also enlarge things.
  • Shout-Out: Some of the experiments' names, numbers, designs, and/or functions:
    • Topper's number (025) is a reference to the date of Christmas Day (December 25).
    • Carmen (123) is based off of and named after Carmen Miranda.
    • Hunkahunka (323) is named after a line in "Burning Love" by Lilo's idol Elvis Presley.
    • Experiment 452 (who never appeared in any work) is named Bob.
    • Houdini (604) is obviously named after the famous escape artist.
  • Single Specimen Species: Every single experiment (sans Leroy and his clones if cloning counts) are the only members of their own unique species, which is also partially why they're "cousins" and not siblings.
    • There are a few "exceptions" (loosely speaking) to this rule, specifically the Stitch-type experiments:
      • Stitch/626 (the original, ultimate, and successful culmination of Jumba's research and experimentation).
      • The Flawed Prototype versions of Stitch: Cyber/000 (Jumba's original Bioweapon Beast Living Weapon that 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).
      • The Evil Counterpart versions of Stitch: 627 (Superior Successor to Stitch with many more powers and completely evil) and Leroy/629 (a straight-up Evil Twin clone of Stitch)
      • 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 Distaff Counterpart of Stitch's line).
  • Toilet Humor: The name of the unseen Experiment 444, Pooperson.
  • The Transmogrifier: Morpholomew (316) can transform targets into other living organisms as long as he has photographic memory of the form he's transforming them into.
  • Tuckerization: Jesstifer (354), named after The Series writer and executive producer Jess Winfield.
  • Turned Against Their Masters: 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.
  • Voice Changeling: Spooky (300) changes his voice whenever he transforms.
  • What Happened to the Mouse?: 628's Experiment Pod, though Word of God admitted that that wasn't meant to be a Sequel Hook; it was just meant as a joke.
  • You Are Number 6: 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.

Experiment series

All the subpages below focusing on individual series of experiments (named after their first digits) feature lists containing each experiment's name, number, pod color (if seen), a description about them (if seen or mentioned), and any appearances they've made between the films, the TV shows (including specific episodes of Lilo & Stitch: The Series), and other media. Some of the more notable experiments even have their own folders.

The general descriptions for each experiment series are as described by The Series executive producer (and the voice of Dr. Jumba Jookiba in Stitch! and Stitch & Ai) Jess Winfield unless noted.
