Characters / Lilo & Stitch: Experiments

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 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!. 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 that are scattered across the island as a result of The Series' pilot movie. Lilo and Stitch make it their mission to seek out all of them and reform them for good.

  • 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), Twang (021),note  Hertz Donut (022),note  Forehead (044), Squeak (110), Bonnie (149), Clyde (150), Nosy (199), Ace (262),note  Wormhole (272),note  Remmy (276),note  Spooky (300),note  Heckler (322), Manners (358), Phantasmo (375),note  Chopsuey (621),note  Angel (624),note  Reuben (625), Stitch (626), 627,note  and Leroy. In addition, Frenchfry (062) can speak fluent French.
  • 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.
  • Animate Inanimate Object: Caused by Phantasmo (375) when he possess any non-living thing.
    • 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 finds his one true place entertaining customers.
  • Attack Reflector: Slugger (608).
  • 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.
  • Balloon Belly: Frenchfry (062) can make delectable meals from almost any foodstuffs, but the resulting meals have absolutely zero nutrition, making the consumer feel like they are never full. They eat and eat until they have swelled up to massive size, then Frenchfry cooks and eats the enlarged individual.
  • Batman Can Breathe in Space: The Series episode "The Asteroid" shows that the experiments can survive the vacuum of space.
  • Big Damn Heroes: Several of the experiments get these after they are turned good. Sparky gets several in Stitch! The Movie.
  • Black Hole Belly: Holio (606) is able to retrieve items that he sucks up in his black hole. Mertle found out the hard way when she demanded her dolls back.
  • Canon Foreigner: The experiments from Comic Zone. The only ones with known names and/or numbers are Slobber (347), Hisee (531) and Tippy.
  • Chained Heat: Link (251).
  • 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.
  • Cuteness Proximity: Mr. Stenchy (254) was specifically designed to invoke this as a way to infiltrate populated areas and then clear them out with an unholy stench.
  • Cyborg: Cyber (000), who actually debuted in the Stitch! anime, thus leaving his status in the canon dubious.
  • Death Ray: Heat (609).
  • Digitized Hacker: Glitch (223).
  • Drill Mole: Digger (529), who looks more like a meerkat than a mole.
  • Drop the Hammer: Hammerface (033).
  • 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.
  • Epic Fail: Two of Jumba's experiments were completely against what he was trying to make.
    • Ace (262). Since Jumba was creating evil experiments, Ace was a failure in that he was the only experiment created that was purely good.
    • Clip (177) was designed to eat an alien fuel source, Uburnium, to create an energy crisis. When programming the experiment, Jumba's computer translated the word "Uburnium" into Jumba's native language; "Hair". So the experiment instead shaved people bald and ate their hair.
  • Epic Flail: Thresher (544).
  • Everything's Better with Dinosaurs: Some of the experiments have traits of dinosaurs; Richter (513) resembles an Ankylosaurus and Slugger (608) resembles a Pteranodon, for example.
  • Expy:
    • Babyfier is a fairy version of Mew with a baby theme and the cuteness turned Up to Eleven, 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 a cross between native Hawaiian, Chinese and Chezcreekian, the last being an obscure language spoken by a minority of people in the rural parts of Chesterfield in North Derbyshire, England.
  • 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 eternal sleep by just bleating at them.
  • Foreshadowing: Their entire existence were first implied by Jumba lying to the United Galactic Federation all the way back in the prologue of the original film itself.
  • Fountain of Youth: Babyfier (151) turns people into babies.
  • Frickin' Laser Beams: Zap (603), who is a living laser beam.
  • "Freaky Friday" Flip: Swapper (355).
  • The Ghost: Even though Jumba made over 600 experiments, we only see about a hundred of them throughout all the films, the first two shows,note  and a few spin-off media. In fact, most of Stitch's predecessors (plus Experiment 628) remain unseen to this day. (The questionably-reliable Lilo & Stitch Wiki on Fandom/Wikia counts 495 unseen experiments.)
  • Giant Enemy Crab: Shortstuff (297), although it's due to a growth ray.
  • 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.
  • Gravity Sucks: Holio (606) can turn into a black hole.
  • 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 'Oe" concert in Leroy & Stitch:
    • Twang (021) is a very talented flutist and harmonica player.
    • 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.
    • 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!
  • 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.
  • Hypnotic Eyes: Swirly (383)
  • I'm a Humanitarian: Surprisingly, Frenchfry has no problem with eating fellow experiments.
  • Instant Mass/People, Just Add Water: Experiments deactivated into pod form are reactivated by coming in contact with water.
  • Involuntary Dance: Carmen (123) and the anime version of Sample (258).
  • Laser-Guided Amnesia: Amnesio (303).
  • 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.
  • Living Lie Detector: Fibber (032).
  • Living MacGuffins: They are the primary focus of Lilo & Stitch: The Series, where the duo have 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.
  • Love Potion: Hunkahunka (323), though his ability's more akin to Cupid's Arrow.
  • MacGuffins: Especially as pods.
  • Make Me Wanna Shout: Yaarp (613).
  • Make a Wish: Wishy-Washy (267), although he grants wishes very literally.
  • Meaningful Name: Every single experiment.
  • Me's a Crowd: Dupe (344).
  • Mons: They could be seen as this.
  • Monster of the Week: All served this purpose within The Series.
  • 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.
  • 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.
  • No Name Given: 627 and 628.
  • 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.
  • Phlebotinum-Induced Stupidity: Spike (319).
  • Plant Aliens: Sprout (509).
  • Pokémon Speak: Gotchu (031) and Woops (600); 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 
  • Ptero Soarer: Slugger (608) looks like a tiny, adorable Pteranodon... but with a baseball bat for a tail!
  • Reality Warper: Shoe (113) controls luck, and Launch (607) is said to be able to erase the universe if he wants.
  • Ridiculously Cute Critter: Mr. Stenchy (254) was specifically designed to be this. Some others qualify as well.
  • Rubber Man: Elastico (345).
  • 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).
  • 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).
  • Shout-Out: Some of the experiments' names and numbers:
    • Topper's number (025) is a reference to the date of Christmas Day (December 25).
    • Squeak (110) is based off of Sniffles.
    • 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 The Series otherwise) is named Bob.
    • Houdini (604) is obviously named after the famous escape artist.
  • Single Specimen Species: Every single experiment.
  • Toilet Humor: The name of the unseen Experiment 444, Pooperson.
  • Tuckerization: Jesstifer (354), named after series writer Jess Winfield.
  • Voice Changeling: Spooky (300)
  • What Happened to the Mouse?: 628's Experiment Pod.
  • You Are Number 6: Technically all of them to Jumba, which plays a role to 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 or Stitch having ever dealt with it.
  • Your Worst Nightmare: Remmy (276) and Spooky (300).

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 Jess Winfield unless noted.
