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, 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 descriptions for each experiment series (named after their first numbers) are as described by executive producer Jess Winfield unless noted.

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).
  • 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).

Description Appearances
001 Shrink Pink Jumba's first experiment is a small purple experiment with a lilac lower jaw and chest, three wobbly legs, two stubby little arms and two floppy antennae with two rings on each antenna. He is designed to zap a ray from his antennae to change the size of objects. He also has the ability to levitate. His picture appears on a newspaper clipping on the wall of Jumba's lab in Leroy & Stitch, along with several other pictures of Jumba and Dr. Hämsterviel's early accomplishments. His name appears under said picture, suggesting that he was named well before the events of the first film. Leroy & Stitch, Stitch!
002 Doubledip Purple A purple opossum-like experiment with two light purple stripes on the back of his ears, beady eyes and an orangenote  nose. He is designed to double-dip food. His one true place is with Mrs. Hasagawa as one of her "cats". He somehow changed in size in Leroy & Stitch. "Mrs. Hasagawa's Cats", Leroy & Stitch
003 Howcome   Experiment unseen  
004 Squawk   Experiment unseen  
005 Truxx   Experiment unseen  
006 Percy   Experiment unseen  
007 Gigi (a.k.a. "Yapper") White See folder below "Yapper", "Amnesio", "PJ", Leroy & Stitch
008 Carmine Red Experiment unseen  
009 Pop Red A small orange and caramel-colored monkey/Cannonball (520)-like experiment with two pink orbs on the top of his head with three stubby multi-colored antennae. He has a white face and stomach and a small red nose, as well as green markings on his rear and back. His tail is a pump which he uses to blow up pink balloons which reform on his tail after they pop. He is designed to use his tail to blow up a balloon to the size of the room he is in, then popping the balloon, discombobulating those involved near the explosion of the balloon and causing frizzy hair. Stitch!
010 Felix Green See folder below "Felix", "Remmy", "Woops", "Snafu", Leroy & Stitch, Stitch!, Disney Stitch Jam
011 Inkstain Green Experiment unseen  
012 Antitherm   Experiment unseen  
013 Furry   Experiment unseen  
014 Kernel White A tan gourd-shaped experiment with a large opening at the top of his head who is designed to pop popcorn for Jumba's movie night. His one true place is in a movie theater. He was mentioned in "Angel" when a re-eviled Jumba lied to Lilo by saying that Angel (624) was this experiment. Leroy & Stitch
015 Ruggles   Experiment unseen  
016 Matt   Experiment unseen  
017 Lidds   Experiment unseen  
018 Puck   Experiment unseen  
019 Clumsy White This experiment's pod was seen in Stitch! The Movie. The pod read 19 instead of 019. Its function is unknown.  
020 Slick Red A fast-talking, pink experiment with a Southern accent and a resemblance to Jumba and Cannonball (520), but with a smaller face and two ebony-black eyes. He is designed to be able to sell anything to anyone. He wears a straw boater hat and bowtie, carries a cane, and acts as a salesperson who never turns down a customer. Lilo and Mertle fought over him to get ahead in a chocolate bar-selling contest/fundraiser. Eventually, Mertle sold him to Reuben (625). Slick was rescued, but Lilo had to give up the contest by giving her last chocolate bar to an ill Gantu as a swap for Slick. His one true place is at a fundraiser, following which he began working for charity, not profit. Slick was one of the experiments Lilo turned to for the capture of Ploot (505), but he didn't provide help besides selling her an umbrella that she later used against Ploot. He is voiced by Jeff Bennett. "Slick", "Ploot", Leroy & Stitch
021 Twang  An orange and yellow long-eared cat/rabbit-like experiment with a white stomach and orange heart-shaped markings on his forehead and all down his back. He has blue tufts of fur coming out of his ears and violet-colored eyes and a red nose. He is designed to play music from Jumba's home planet, increasing his power and growth through the sympathy he receives from his beautiful music. However, he also grows meaner and uglier the more powerful he gets. A talented player of the harmonica and flute, he's also super-smart and athletic, making him very popular. In the English dub of the anime Stitch!, he is named "Flute" and is numbered 145, although canonically 145 is actually the number of the unseen Bragg. Stitch!
022 Hertz Donut Purple A green seahorse-like experiment with purple eyes, a doughnut-like mouth, six ears, and a long curling antenna winding behind his head. He can confine, and prevent movement by firing toruses at a target. He has the ability to speak English, and hops instead of walks. Stitch!
023 Cyclo   Experiment unseen  
024 Hamlette  An experiment designed to turn objects into ham. She was activated when Mrs. Hasagawa's cats were activated, as indicated by Gantu's experiment computer, but did not physically appear in the episode. She was referred to in "Remmy" when Pleakley said, "Is that the one that turns everything into ham?" This experiment is believed to look like a yellow Topper (025)-like experiment with a long snout. An experiment matching that description can be seen in Leroy & Stitch. "Mrs. Hasagawa's Cats" (pod), Leroy & Stitch (supposedly)
025 Topper White A small yellow star-shaped creature with a little antenna on his head. He is designed to be a beacon to signal the alien attack fleet, although the official Disney website stated his purpose is to keep people awake with his bright light. Topper is given to a little girl as a Christmas present, then placed atop the local Christmas tree and emits a light so bright that aliens from other galaxies can see him from Earth. His number refers to Christmas Day (December 25). He is voiced by Tress MacNeille. "Elastico", "Topper", Leroy & Stitch, Stitch!, Disney Stitch Jam 2note 
026 Pawn   Experiment unseen  
027 Plushy   Experiment unseen  
028 Lori White Experiment unseen  
029 Checkers Yellow A yellow and purple centipede-like experiment that sits curled up like a crown on people's heads. He is designed to make his wearer a king or queen by hypnotizing those around them, with the exception of higher experiments. The victims retain their normal personality while under its control, and the effect immediately wears off once Checkers is removed. Lilo first donned him, but her good intentions got many people arrested by Mertle for being "troublemakers" when they accidentally disobeyed Lilo's rules. When Lilo decided to step down, Gantu took Checkers and was in power until Stitch gathered several experiments to help overthrow him. His one true place is as a decorative crown for festivals. He will also jump off his wearer if he eats really spicy foods. He is voiced by Billy West. "Checkers", Leroy & Stitch, Stitch!
030 Vialet  Believed to be a small purple experiment who is similar to Gotchu (031) and has a dragon-like tail and only two arms. An experiment matching that description can be seen in Leroy & Stitch. Leroy & Stitch (supposedly)
031 Gotchu  An orange lobster-like experiment who is designed to run around and pinch things with his four pincers, saying "Got you!" every time he does so. His one true place is with Mrs. Hasagawa as one of her "cats". "Mrs. Hasagawa's Cats", Leroy & Stitch
032 Fibber  A small orange experiment with a small body, small arms and legs, a large head with a dark orange mark on the forehead, little antennae, a little mouth, a round nose, black eyes and four ears. He is a Living Lie Detector who, when someone tells a lie, beeps loudly and the pattern on his forehead lights up. The bigger the lie, the louder he beeps, and the brighter the pattern lights up. Fibber was captured by Gantu, but rescued by Lilo and Stitch in "Snafu". He was also part of Pleakley's E.A.R.W.A.X. group in "Spike", which was a mistake in the episode's production since he was captured by Gantu at the time. He is voiced by Jeff Bennett. "Fibber", "Spike", "Remmy", "Woops", "Snafu", Leroy & Stitch
033 Hammerface (a.k.a. "Hammerhead") White A blue-gray dinosaur-like experiment with short forearms and a thick tail and legs. He is designed to drive in nails around Jumba's house with his hammer-shaped head/face, but at times he will pound living things. 033 was found (in pod form), activated, named, and trained by Gantu. He was turned into an army of 100 weaklings by Dupe (344), and rescued by Lilo's rescue team in "Snafu". 033 was called "Hammerhead" by Pleakley in "The Asteroid". In Stitch! The Movie, his number is 124. "The Asteroid", "Dupe", "Remmy", "Woops", "Snafu", Leroy & Stitch
034 Splort   Experiment unseen  
035 Philip   Experiment unseen  
036 Poki  A small yellow and brown opossum-like experiment with a spiked tail who is designed to poke holes in liquid containers. He was seen in "Shoe" helping to convert Jumba's ship into a hotel. "Shoe", "Remmy", Leroy & Stitch
037 Snipper   Experiment unseen  
038 Plats   Experiment unseen  
039 Atlas   Experiment unseen  
040 Backhoe  A gray mole-like experiment with large black claws. He is an efficient digger designed to scrape up vegetation. He was part of the "rebellion" in "Checkers", and he dug the pool for Jumba and Pleakley's "Bed and Not Breakfast". "Shoe", "Checkers", "Remmy", Leroy & Stitch, Disney Stitch Jam 2note 
041 Kitsch   Experiment unseen  
042 Itch   Experiment unseen  
043 Cubesteak   Experiment unseen  
044 Forehead Green A pink, four-headed, mustached experiment with four arms and four red bowties on his necks that speaks English. He is designed to sing barbershop music off-key, annoying anyone who hears it (specifically, the first three heads sing well, but then the fourth sings off-key). His one true place is with Mrs. Hasagawa as one of her "cats". "Mrs. Hasagawa's Cats", Leroy & Stitch
045 Melvin   Experiment unseen  
046 Wedgie   Experiment unseen  
047 Lorider  A blue platypus-like experiment with an accordion-like body who is designed to pull people's pants down. He delights in humiliating people, and he won't stop embarrassing them until he gets the full effect. Stitch!
048 Echo   Experiment unseen  
049 Picker White This experiment's pod was seen in Stitch! The Movie. The pod read 49 instead of 049, possibly due to the viewing angle. Its function is unknown.  
050 Dunk   Experiment unseen  
051 Hocker Green A green experiment with a huge blue nose and a yellow spot around his eyes and a yellow stripe on his ears and tail.note  He is designed to spit acidic saliva that can burn through wood in about three seconds. His one true place is with Mrs. Hasagawa as one of her "cats." "Mrs. Hasagawa's Cats", Leroy & Stitch
052 Coco  A chocolate-colored pink-haired lizard/Stitch-like experiment who is designed to turn things into chocolate. He appeared in a Lilo & Stitch comic in Disney Adventures magazine where he was given to Lilo by Stitch for her birthday. Disney Adventures
053 Whine   Experiment unseen  
054 Fudgy Blue An experiment made of chocolate that looks like a blob who is designed to drown people in his sticky sweetness. When he was activated, he was called 119, and he was mistaken for Experiment 611. The mistake with his number was due to Jumba's untidy database, although Jumba later corrected this mistake. He was rescued in "Snafu". In the Stitch! anime, Hämsterviel used him to invade a chocolate factory. In this appearance, Fudgy was modified to grow larger in size by eating chocolate, similar to Tank (586)'s ability of growing larger by eating metal. "Houdini", "Snafu", Stitch!
055 Snarfhonk   Experiment unseen  
056 Nibbiolo   Experiment unseen  
057 Tenderizer   Experiment unseen  
058 Shortsheet   Experiment unseen

062 Frenchfry White A small, gray and white, mustached experiment with four arms with three fingers on each hand, black eyes, a round nose, a little mouth, short ears, a chef's hat, and a spatula for a tail. He is designed to use his Super Speed to instantly prepare food or whip up a mini-tornado in battle. He is also the only experiment in the series that speaks French. He was designed to be Jumba's personal chef, but instead he made unhealthy food that quickly made people fat, then he ate the fattened victims. However, he stopped when he learned that healthy food could be just as delicious. His one true place is running a healthy French fry hut. He is voiced by Rob Paulsen. "Frenchfry", Leroy & Stitch

072 Stickystuck   Experiment unseen  
073 Cornerpiece   Experiment unseen  
074 Welco White A pink balloon dog-like experiment with dark blue humanoid eyes, big lips and a heart-like tail. She can blow indestructible bubbles that last only temporarily. Her bubbles can somewhat stick together, and therefore can be formed into a cloud. Her body contains a form of helium or another light air, and this causes her to float. This experiment's pod was seen in Stitch! The Movie, where the pod read 74 instead of 074. Stitch!
075 WooWoo   Experiment unseen  
076 Bath Matt   Experiment unseen  
077 Zawp  A fat, purple, Nosy (199)-like experiment with black nails, a dark blue stripe around his torso between his chest and stomach, a dark blue circle on the top of his head, dark blue-striped ears, a larger belly and a slightly smaller, gold nose. He is designed to irritate people with his constant snoring. His one true place is with Mrs. Hasagawa as one of her "cats". "Mrs. Hasagawa's Cats", Leroy & Stitch
078 Snozzle White This experiment's pod was seen in Stitch! The Movie. The pod read 78 instead of 078. Its function is unknown.  
079 Fogger   Experiment unseen  
080 Dan   Experiment unseen  
081 Backscratcher   Experiment unseen  
082 Plunge White This experiment's pod was seen in Stitch! The Movie. The pod read 82 instead of 082. Its function is unknown.  
083 Grimple   Experiment unseen  
084 Subwoof   Experiment unseen  
085 Screwup   Experiment unseen  
086 Clink  A big, green, mouthless crab-like experiment with four legs, two large claws and a window on its chest. Able to capture and confine any other experiment inside the holding tank in his stomach by splitting in half, surrounding whatever he wants to catch, and joining together again. When Clink splits in two, he works with himself, yet he seems to have a separate mind for each half. Twenty years in a future when Hämsterviel ruled Earth, Lilo, Stitch, and Skip encountered Clink in the possession of Hämsterviel. "Skip"
087 Puddles   Experiment unseen  
088 Decrisper   Experiment unseen  
089 Skip  A small, pudgy, purple hourglass-shaped experiment with small ears, a big round nose, and a stubby tail. He was designed to skip time by ten minutes, because Jumba was too impatient to wait for his microwave to reheat his leftovers, but there was an error in his programming that causes him to skip time by ten years instead of ten minutes. Fortunately, he has a reset button on top of his head (seen as a light green patch); when activated, Skip turns upside-down and reverses the time back to when his ability was first activated. Lilo used him to jump ahead ten years and become a teenager, then another ten years later to become a full-fledged adult. However, since Lilo and Stitch were gone for twenty years, no one was there to catch experiments except for Gantu and Reuben, resulting in Dr. Hämsterviel conquering and ruling the Earth. "Skip", Leroy & Stitch
090 Fetchit  This experiment was activated alongside Mrs. Hasagawa's "cats" in the episode of the same name. Its function is unknown.  
091 Nutsy   Experiment unseen  
092 Gutman   Experiment unseen  
093 Unkind   Experiment unseen  
094 Louis B. White This experiment's pod was seen in Stitch! The Movie. The pod read 94 instead of 094. Its function is unknown.  
095 Coaster   Experiment unseen  
096 Cable Dude   Experiment unseen  
097 Dogalarm   Experiment unseen  
098 Cooper   Experiment unseen  
099 Spot  A spotlight experiment that was supposed to be in "Spike" but was removed, and was supposed to appear later. He shines a spotlight on people. Supposedly looks like Heat and may have been seen in Leroy & Stitch, but nothing has been confirmed. Leroy & Stitch (supposedly)

    Gigi a.k.a. Yapper (Experiment 007) 
https://static.tvtropes.org/pmwiki/pub/images/gigi_experiment_007.png
Voiced by: Tress MacNeille
Debuted in: "Yapper" (Lilo & Stitch: The Series Season 1, Episode 8)

A white Shih-Tzu-like experiment who is designed to annoy people with her constant barking, but otherwise behaves like a typical "good dog". She was adopted by Mertle Edmonds (who didn't even know she adopted an alien) as "Gigi". Lilo nicknamed the experiment "Yapper", hence the title of the experiment's debut episode, but Leroy & Stitch listed the experiment by the name Mertle gave her. Obviously, her "one true place" is being Mertle's pet "dog".


  • Alien Animals: The one known experiment that Jumba made who looks like a normal Earth mammal, which makes her adoption by the weirdness-hating Mertle all the more fitting.
  • Aliens Speaking English: Was revealed to be capable of speaking English in Leroy & Stitch, which surprised Mertle (and the movie's audience). After the Leroy incident, Gigi convinced her owner off-screen to finally stop hating on Lilo and join her ʻohana.
  • 11th-Hour Superpower/Suddenly Voiced: Not that the above revelation matters in battle, but still.
  • Non-Malicious Monster: Her ability is more aggravating than evil, and she behaves like a regular Earth dog anyway.
  • Poke the Poodle: While most experiments are designed to wreak havoc and bring about chaos, Gigi was designed to annoy people with her barking.
  • Sequel Non-Entity: Does not appear in the anime, although it could be justified that she's still living with Mertle.
  • Shout-Out: She has the number of a famous secret agent, despite having no secret agent traits herself.
  • What Happened to the Mouse?: Despite being adopted by one of The Series' most frequently recurring characters, she only made minor appearances in two more episodes ("Amnesio" and "PJ") before reappearing in Leroy & Stitch. She was even absent when Mertle adopted Hämsterviel in one episode.

    Felix (Experiment 010) 
https://static.tvtropes.org/pmwiki/pub/images/felix_experiment_010.png
Voiced by: Tress MacNeille, Steve Blum (Stitch!)
Debuted in: 'Felix' (Lilo & Stitch: The Series Season 1, Episode 31)

A green anteater/elephant-like experiment who is designed to be an effective cleaner, although he is a bit too obsessed with cleanliness. He was reprogrammed to take care of this issue, but it made him obsessed with dirtiness, with Lilo calling him an "Oscar" in this dirt-loving programming. He was given to Gantu at the end of his episode, but was later rescued in "Snafu".

104 Laspe   Experiment unseen  
105 Fold   Experiment unseen  
106 Spindle   Experiment unseen  
107 Mutilate Yellow or Purple This experiment's pod was seen in Stitch! The Movie. Its function is unknown. The 1-series' corresponding color was originally going to be yellow, but was changed to purple for reasons unknown.  
108 Nudge   Experiment unseen  
109 Sounder   Experiment unseen  
110 Squeak  A small red mouse-like experiment that vaguely resembles Sniffles from Warner Bros.' Merrie Melodies series. He is designed to annoy entire planets with his never-ending talking. He first appeared in "Spike", when Jumba was testing his "Evilliminator", a new idea for turning experiments from bad to good, on him and it did not work. He later appeared in Leroy & Stitch when he recalled to Mertle about a nightmare he once had, but was immediately stopped when Leroy fired a blaster close to him. He is voiced by Rob Paulsen. "Spike", Leroy & Stitch, Stitch!
111 Mulch Blue A red experiment that resembles a push mower who is designed to tear up the ground beneath his feet. His one true place is with Mrs. Hasagawa as one of her "cats". "Mrs. Hasagawa's Cats", Leroy & Stitch
112 Toons Green A yellow platypus-like experiment with an orange mane and a rectangular vacuum-like mouth who can bring 2D images to life by consuming a 2D subject and spitting it back out, making it 3D. Stitch!
113 Shoe Purple A green and white sloth-like experiment with a wiry body and a round face with black eyes, a small dark purple round nose, a wide mouth and two long, curved horns. He is able to control luck with his horseshoe-like horns, causing good luck when they are up and bad luck they are down. His mode can be switched by flipping the horns. His one true place is at a miniature golf course, where he makes people score holes-in-one. "Shoe", Leroy & Stitch
114 Skyooz   Experiment unseen  
115 Sellby   Experiment unseen  
116 Switch   Experiment unseen  
117 Tock   Experiment unseen  
118 Fink   Experiment unseen  
119 Inverto Blue This experiment was misunderstood as Experiment 611, as Gantu read its pod upside-down in "Houdini". He was reported by Dr. Hämsterviel as a chocolate experiment who drives people into his sweetness, which is actually Experiment 054 (Fudgy).  
120 Snafu Purple A small, dark green and teal, octopus-like experiment with a roughly reptilian face, a wide mouth, small white eyes with black pupils, a small round body, little arms and legs with small hands and feet, a little tail, black markings on his back, and six tentacles on his large dome head; three on each end of his head. He is designed to foil enemy plans by any possible means. He will ruin any plans to catch him; the only way to do so is by accident. Named for the military acronym SNAFU (Situation Normal: All Fouled Up). "Snafu", Leroy & Stitch
121 Sappy   Experiment unseen  
122 Dorkifier Blue A pink and white calf-like experiment with two horns, a red nose and purple hooves. He is designed to zap a pink ray from his horns that changes anyone's appearance into something ridiculous. The new dorky clothes can only be taken off when his horns are turned down. Stitch!
123 Carmen Pink A pink, blue-eyed, antenna-less, Angel (624)-like experiment, wearing a headdress of fruits and holding a maraca in each of her four hands. She is designed to make people dance until they drop by firing pink balls of energy out of her maracas at victims. The effect can be canceled when she claps her maracas together. She is modeled after her namesake Carmen Miranda. She is voiced by Tress MacNeille in the anime's English dub. "Remmy", Leroy & Stitch, Stitch!
124 Rhymer  Hammerface was mistakenly labeled 124 in Stitch! The Movie due to Jumba's untidy database. This experiment's appearance, as well as its function, remain unknown.  
125 Gibberish   Experiment unseen  
126 Stank  A black and white skunk-like experiment with a beak, three antennae on her head and two on her tail. She is able to shoot explosive pellets that release an unbearable stench upon impact. She falls in love with Mr. Stenchy, who has a similar stench-releasing ability, in the Stitch! anime. When the stenches of Stank and Mr. Stenchy combine, they form a perfect aroma. In the English dub of the anime, Stank is referred to as "Skunkuna" on multiple occasions and is the creation of Dr. Hämsterviel, which contradicts Jumba's genius as he was the creator of the 629 genetic experiments. Stitch!
127 Dembums   Experiment unseen  
128 Bugby Purple A small green mosquito-like experiment with four eyes who was designed to turn whole civilizations into harmless little insects. Anyone turned into an insect can understand all other insects and arachnids. The only way to reverse the effect is with a machine built by Jumba. He was later reprogrammed to only turn inanimate objects into insects. His one true place is helping farmers by turning rocks into swarms of aphid-eating ladybugs. He is voiced by Grey DeLisle. "Bugby", Leroy & Stitch
129 Crutch   Experiment unseen  
130 Bonez   Experiment unseen  
131 Poik   Experiment unseen  
132 Spoony   Experiment unseen  
133 PJ White An orange and tan koala-like experiment with a white face, a wide mouth, red nose, black eyes, yellow-tipped antennae that mix with thin rabbit-like ears, and a functioning blow-horn for a tail (reminiscent of Harpo Marx's trademark horn) which he squeaks instead of speaking. He wears joke eyeglasses with a fake nose and mustache resembling those of Groucho Marx. He is designed to play practical jokes on people, hence his name P(ractical) J(oker). His one true place is as an opening act for Moses's hula gig. In the impromptu "Aloha ʻOe" concert and group photo taken at the end of Leroy & Stitch, and on Disney.com's now-removed experiment gallery, PJ is seen without his glasses. "PJ", Leroy & Stitch, Stitch!
134 Shredder  A green experiment with sharp steel teeth, large ears and a blue nose. He is designed to shred important documents. His one true place is with Mrs. Hasagawa as one of her "cats". "Mrs. Hasagawa's Cats", Leroy & Stitch

147 Newton   Experiment unseen  
148 Weasel  Believed to be a brown weasel-like experiment who is designed to climb up planetary leaders' pant legs during public appearances. An experiment matching that visual description can be seen in Leroy & Stitch. Leroy & Stitch (supposedly)
149 Bonnie Purple See folder below "Bonnie & Clyde", "Spike", "Snafu", Leroy & Stitch, Stitch!
150 Clyde Purple See folder below "Bonnie & Clyde", "Spike", "Snafu", Leroy & Stitch, Stitch!
151 Babyfier White A small, pink, koala/fairy-like experiment with a big head with a baby-like face, tiny purple insect-like wings, stubby legs, short stubby ears, plump cheeks, blue nose, a yellow pacifier in his mouth and a long, dark pink-striped, rattle-shaped tail. He is designed to disable planets by turning adults into babies with a pink powder shaken from his rattle-like tail. The antidote is a mix of two teaspoons of applesauce, one cup of milk, three bananas, and 100% Kona coffee. His one true place is at the animal shelter making older dogs young again, thus making them more appealing to potential adopters. In the Stitch! anime's third season, he was reprogrammed by Hämsterviel to turn people into toddlers instead of babies, and was renamed "Toddler-fier" in this appearance. "Babyfier", "Ploot", Leroy & Stitch, Stitch!
152 Mama Frita   Experiment unseen  
153 XYZ  Pleakley described this experiment in the Stitch! anime as "the pants zipper opener".  
154 Frapp   Experiment unseen  
155 Burger   Experiment unseen  
156 Shopahol   Experiment unseen  
157 Hotl Red This experiment's pod was seen in the experiment profiler special feature on the Lilo & Stitch 2: Stitch Has a Glitch DVD. Its function is unknown.  
158 Finder Purple A red aardvark/shrew-like experiment with little arms and legs, a short, stumpy tail, a long snout, black eyes, and large rabbit-like ears. He is designed to find anything and honk when he finds it, even spin his ears like helicopter blades to be able to fly if necessary, in order to find what he has been asked to locate. His one true place is operating a "Lost and Found" service on Lahui Beach, with "Lost and" struck-out. He was in the rescue party for "Snafu". He is called 458 in his episode, but in Skip's episode and the credits for Leroy & Stitch, he is called 158. "Finder", "Drowsy", "Skip", "Ploot", "Snafu", Leroy & Stitch, Disney Stitch Jamnote

176 Allsox Yellow This experiment's pod was seen in Stitch! The Movie. Its function is unknown.  
177 Clip White A small, yellow hairball-like experiment with a pink bow, dark blue eyes, and long scissor-like claws. She was designed to eat uburnium (an efficient, cheap, and abundant fuel used in outer space) in order to create a fuel crisis. However, in Jumba's native language, the word "uburnium" closely resembles the word for "hair", so she eats hair instead of uburnium. As she eats more hair, she grows larger and larger, to the point where she can only be tamed by shampoo and hair conditioning products. Her one true place is cutting hair at Kokaua Town's beauty salon. Stitch tried to suggest the name "Hairy" to Lilo. In the anime, she appears to also have the ability to fly. She is voiced by Tress MacNeille. "Clip", "Elastico", "Checkers", Leroy & Stitch, Stitch!

Bonnie (149) on the left and Clyde (150) on the right. Heights are approximated from screenshots of The Series.
Bonnie voiced by: Tress MacNeille, Mary Elizabeth McGlynn (Stitch!)
Clyde voiced by: Rocky McMurray (Lilo & Stitch: The Series), Jeff Bennett (Leroy & Stitch)
Debuted in: 'Bonnie & Clyde' (Lilo & Stitch: The Series Season 1, Episode 36)

An experiment duo who are designed to steal things. Bonnie is a small, female, green koala-like experiment with a (supposedly) cunning mind, while Clyde is a large, male, yellow-brown bear-like experiment with a cybernetic left arm. They are the only rehabilitated experiments who were convicted criminals; their "one true place" was in the Kokaua Town Prison, though they were paroled in "Snafu".


    Nosy (Experiment 199) 
https://static.tvtropes.org/pmwiki/pub/images/nosy_experiment_199.png
Voiced by: Bobcat Goldthwait, Roger Craig Smith (Stitch!)
Debuted in: 'Nosy' (Lilo & Stitch: The Series Season 1, Episode 25)

A reddish wombat/pig-like experiment who is designed to snoop out and reveal people's most embarrassing secrets, though it's usually useless gossip. He was given to Gantu at the end of his episode, but escapes in "Woops".


  • Aliens Speaking English: His function wouldn't have as much of an effect towards humans if he didn't speak English.
  • Cannot Keep a Secret: 'Cause he's designed to expose them.
  • Dirty Coward: To an extent, as he'll run off screaming if someone decides to attack him. Granted, he has no actual fighting ability whatsoever, so he would be useless in an actual fight.
  • Escape Artist: Another one of his abilities, although he does gets captured more than once in his debut.
  • Expy: Of Pain from Disney's Hercules, who has a similar personality, a similar appearance, and the same original voice actor.
  • Gag Nose: Fittingly has a very large nose for his face.
  • Multiple Reference Pun: His name refers to both his big nose and his primary function of prying into the affairs of others.
  • Nothing Personal: He can be obnoxious at times, but he's never malicious about revealing other people's secrets; he's just doing what he was programmed to do. In Pleakley's therapy session, he even admits it's a compulsion that he somewhat regrets.
  • Secret Chaser: He's designed to find out secrets from anyone.
  • The Sneaky Guy: Does a bit of stealth and spying to fulfill his function.

200 Adam   Experiment unseen  
201 Geigenstein White This experiment's pod was in Mrs. Hasagawa's dish in "Mrs. Hasagawa's Cats", but it was not activated. Its function is unknown.  
202 Jam Red A purple bat/lizard-like experiment with four arms, a lion-like tail, large wings on his shoulders and a Stitch-like face. He is designed to jam radars with his high-pitched screech. He was activated at the end of Stitch! The Movie, although his pod was mislabeled as 455. He is voiced by Frank Welker. Stitch! The Movie, Leroy & Stitch
203 Snipe Green This experiment's pod was seen in Stitch! The Movie. Its function is unknown.  
204 Nosox Blue A gray experiment shaped like a four-legged washing machine. He is designed to make socks disappear. He was among the twelve new pods Lilo and Stitch brought home in "Drowsy". Nosox was one of the experiments rescued in "Snafu", because Gantu caught him around "Amnesio". "Snafu", Leroy & Stitch, Stitch!
205 Cheney  This experiment's pod was seen in "Skip". Its function is unknown.  
206 Maggie   Experiment unseen  
207 Barcode   Experiment unseen  
208 Hoax   Experiment unseen  
209 Smoot   Experiment unseen  
210 Retro Blue A small orange mammalian/reptilian dinosaur-like experiment with a purple nose, tiny gold-tipped ears, gold markings on his back and spots around his eyes and a thick, short tail and legs. He is designed to turn enemy weapons and technology into their most primitive state by wrapping his tongue around the object, rendering the object useless as he lets go. This process also works on people and other items, and it can be reversed by spanking his bottom three times while his tongue is wrapped around the de-evolved person or thing. His one true place is making a prehistoric zoo. He is voiced by Frank Welker. His appearance under Hämsterviel's possession in "Woops" was an error. In the Stitch! anime, it is also shown that Retro's ability can also work on experiments, as when Stitch was hit by Retro's powers in one episode, he reverted to his original destructive programming. "Retro", "Woops", Leroy & Stitch, Stitch!
211 Jangle   Experiment unseen  
212 2-Late   Experiment unseen  
213 UHF   Experiment unseen  
214 Pix  A blue camera-like experiment with small arms and three legs that are similar to a tripod. He is designed to take only bad pictures of people. He takes the pictures with his "nose" and develops the pictures like an instant camera with the pictures coming out of his mouth. His one true place is with Mrs. Hasagawa as one of her "cats".

222 Poxy Green A tiny pale green-grey germ-like experiment with pink-purple spots and four white grey-tipped antennae. He is designed to transmit disease to popular planetary leaders and disable them. The symptoms are purple pimples, smelly feet, a swollen eye, and uncontrollable burping. When he turns to good, he could cure health problems. Ends up with (actually in) Gantu. He was rescued in "Snafu" and later uses his powers to cure people according to a game on the Lilo & Stitch 2: Stitch Has a Glitch DVD. He is voiced by Tress MacNeille. This experiment's design was first shown on the Lilo & Stitch DVD's "Create Your Own Alien Experiment" bonus feature game, alongside two experiments who were never seen in The Series. "Poxy", "Snafu"
223 Glitch Green A bright green experiment that resembles a cross between Morpholomew (316) and Poxy (222) with a round torso, pudgy arms and legs, a large round head with a little mouth, a round nose, dark green eyes, a small arrow-shaped mark above his facenote  and two thin antennae. He is designed to turn technology against its user by entering machines and electronics, using technopathy, and making them malfunction, operating like a computer virus. Lilo tricked him into being downloaded into her video game. He was released as of Leroy & Stitch to help fight the Leroy clones. His one true place is Lilo's video game, rendering the games harder. "Glitch", Leroy & Stitch
224 Tweak   Experiment unseen  
225 Mashy  Believed to be a light blue dinosaur-like experiment, with a huge mouth, with tiny horns above each nostril, two large ears, and a large body. An experiment matching that description can be seen in Leroy & Stitch. He was presumably designed to crush orbs of precious uburnium in his mouth, which Clip (177) was originally made to do, due to an error on Jumba's part, uburnium being close to the word for hair on his planet. Leroy & Stitch (supposedly)
226 Combo   Experiment unseen  
227 Butter  A large tan mammoth-like creature with two tiny little antennae, a big round green nose instead of a trunk, green markings on his back, legs at the middle of his torso with external toes, a big hump near his face, and tusks as large as the entire front of his body. Able to batter through even the thickest doors. Leroy & Stitch
228 Melty Green A small, red, dragon-like experiment with small bat-like wings, a reptilian head with thin pointed ears, black eyes, and a thin body. He is designed to melt enemy fortresses, weapons, and transportation, among other things, with the bright blue blasts from his mouth. His one true place is burning metal at a recycling plant. He is voiced by Tress MacNeille. "Melty", "Remmy", Leroy & Stitch
229 Kingpin  Believed to be an unlucky experiment that looks like a yellow ten-pin bowling pin with rabbit ears, black eyes, white stomach, and a large light blue nose. An experiment matching that description can be seen in Leroy & Stitch. He is presumably designed as a target for military war games. Leroy & Stitch (supposedly)
230 Checkup   Experiment unseen  
231 Sprok Blue This experiment's pod was seen in the experiment profiler special feature on the Lilo & Stitch 2: Stitch Has a Glitch DVD. Its function is unknown.  
232 Poser Green This experiment's pod was seen in Stitch! The Movie. Its function is unknown.  
233 Pitch   Experiment unseen  
234 Shush Green A reddish-pink opossum/mouse-like experiment with black eyes, large ears and a speaker at the end of its long and fluffy raccoon-like ringed tail. It is designed to eavesdrop on private enemy conversations. To stop this experiment from eavesdropping, someone must pat it on the head, so it curls up its speaker-like tail and folds its large ears downward. Shush's one true place is with Cobra Bubbles as a CIA operative. This experiment's gender is disputed; the experiment was referred to as male by Lilo and Pleakley in its episode, but fan wikis label the experiment as female. "Shush", Leroy & Stitch
235 Docker White This experiment's pod was in Mrs. Hasagawa's dish in "Mrs. Hasagawa's Cats", but it was not activated. Its function is unknown.  
236 Charger Green This experiment's pod was seen in the Flash game Stitch Speed Chase on Disney Channel's website. Its function is unknown.  
237 Blip   Experiment unseen  
238 Bworp  This experiment's pod was seen in the Flash game Stitch Speed Chase on Disney Channel's website. Its function is unknown.  
239 Clickster  This experiment is mentioned in "Drowsy" when Pleakley said, "Experiment 239 designed to cause traffic jams." However, it does not cause traffic jams; it was mistaken for Stopgo (102). Its actual function is unknown.

She is designed to scare people with a loud high-pitched shriek. Her one true place is Nani's alarm clock. She is voiced by Tara Strong. "Belle", Leroy & Stitch
249 Sproing  A dark blue and white roughly koala-like experiment with a spring-like body, a wide mouth, round nose, dark eyes, two little ears and little antennae who is designed to launch boulders. Sproing's one true place is helping people reach high places. Leroy & Stitch
250 Lacrosse   Experiment unseen  
251 Link Green A small bright yellow, pudgy, vaguely rabbit-like experiment with red eyes, a small round nose, and long striped antennae that shoot a slimy bluish glue-like substance that will only dissolve in mud. He is designed to bind together incompatible individuals, usually by the hand or wrist. His one true place is helping arguing couples bungee jump. "Link", Leroy & Stitch, Stitch!
252 Crete   Experiment unseen  
253 Uncrete   Experiment unseen  
254 Mr. Stenchy  An irresistibly cute pink experiment with a round head, big blue eyes, two puffy antennae and a small tuft of hair atop his head, a small pudgy body, and a fluffy stomach. He is designed to trick his enemies into taking him into their homes. Once there, Mr. Stenchy lets out a noxious odor, released 42 hours after activation. Mr. Stenchy's one true place is on Pleakley's home planet of Plorgonar, where his stench is considered a rare and valuable perfume. He somehow ended up back on Earth for Leroy & Stitch, stench-free, suggesting he can either control the smell or it wears off after a while. He is voiced by Frank Welker in The Series. "Mr. Stenchy", Leroy & Stitch, Stitch!, Disney Stitch Jam 2note 
255 Mrs. Sickly  An experiment that bears a striking resemblance to Mr. Stenchy, except for her pale green coloration. Like Mr. Stenchy, she is designed to be an irresistibly cute stink-bomb. She appeared in the Stitch! anime and lived with Mr. Stenchy. Apparently, if the two of them are put together, they can devastate entire planets. She is voiced by Tara Strong. Stitch!
256 Addy   Experiment unseen  
257 Rattat   Experiment unseen  
258 Sample White A small, bright orange,note  koala/cat-like experiment with a wide mouth, a big round nose which functions as a microphone, stubby and soft paws, a fluffy stomach, black pupil-less eyes, and big round ears resembling speakers. He is designed to annoy enemies by looping random sounds with his mouth or his ears. He can also roll into a ball and climb walls, much like Stitch. His one true place is providing backbeats for an originally rhythm-less band named Fox Roswell. He has no voice actor due to his unique ability. He was in the rescue mission for "Snafu". In the Stitch! anime, he was modified by Hämsterviel to fire yellow rings of dust from his ears. Those who touch this dust will dance uncontrollably, similar to Carmen (123)'s ability. "Sample", "Snafu", Leroy & Stitch, Stitch!
259 Rash   Experiment unseen  
260 GPS   Experiment unseen  
261 B. V. Beaverton   Experiment unseen  
262 Ace Yellow A bright red, roughly koala/dragon/superhero-like experiment with a muscular body, yellow chest and stomach, a manly face, White Gloves-style front paws (hands), a wide mouth, a blue nose, dark eyes, pointed ears and small antennae as well as four arms, Super Strength, warm ice-melting breath, and dazzling teeth. He has one fatal error: he has no evil function; a failed experiment that is pure good, and to top it off, he is the only experiment programmed not to cause trouble. When Jumba had his membership revoked from E.G.O. (Evil Genius Organization), Lilo and Stitch tried to trick the head of E.G.O. into thinking that Jumba was still evil. The plan worked until the head of E.G.O. saw a screen of Ace rescuing a cat from a house on fire. His one true place is balancing out Jumba's evil and acting as a local do-gooder. His experiment number-–262-–is the inverse of 626-–Stitch's number; Ace is a purely heroic experiment, and Stitch had been designed to be purely destructive, thus, the opposite of 262. Ace is voiced by Jeff Bennett. He also appeared in a special episode of the Stitch! animenote  where he's also shown to speak English and has the ability to fly. "Ace", Leroy & Stitch, Stitch!
263 SFS   Experiment unseen  
264 Poach   Experiment unseen  
265 Wip   Experiment unseen  
266 10x   Experiment unseen  
267 Wishy-Washy Green A pudgy lavender-bluish teddy bear-like experiment with fairy-like wings that enable him to fly. He also has a "wand" on his head that lights up every time a wish is granted, and is also good for throwing an unsuspecting opponent, like Stitch. He is designed to be a wish giver that grants any wish he hears, but the wishes are granted literally and may not turn out quite as expected. In addition to rejecting wishes for more wishes, he also has a wish limit, indicated by a small meter on his stomach which starts out completely red. As wishes are granted, the meter slowly goes down. When white, all the wishes are gone, and he is deemed useless. "Wishy-Washy", Leroy & Stitch, Stitch!
268 Celsenheit   Experiment unseen  
269 Gyrotta   Experiment unseen  
270 Gillmore   Experiment unseen  
271 Noso   Experiment unseen  
272 Wormhole  A purple and cyan caterpillar-like experiment with black eyes, two dark purple-tipped antennae, four dark purple-tipped legs and blue mouth inside. He first appeared in the Stitch! anime, where he is shown to be nice instead of evil and can speak fluent English. His antennae also flicker and light up. He can fold himself into a ball while in a levitating-like position, and this opens up a wormhole directly behind him, specially designed to connect to the exact moment that one enters, but in a parallel universe. These wormholes last for a few days period, and Wormhole can locate any one of them which is open. While he can create one at any time, he has absolutely no power over which universe they may lead to. Leroy & Stitch erroneously gave him the number 275, which is Tickle-Tummy's number. Stitch!
273 Boxboom   Experiment unseen  
274 Alexander Green This experiment's pod was seen in "Drowsy" under Lilo and Stitch's possession. Its function is to make lots of long distance calls on your telephone to run up the cost of your phone bill.  
275 Tickle-Tummy White A round, pink experiment with rabbit-like ears, no legs, a clownish face, two hands with long fingers and a large patterned torso, which she uses to jump really high. Her primary function is to tickle people, since she tickled Reuben into hysterics after he denied being ticklish. She was caught by Gantu and rescued in "Snafu". Fans speculated that she may be Experiment 628 since she was not listed in the end credits of Leroy & Stitch (where 275 was Wormhole, thus 272 being listed as "Mamf"), but the creators confirmed that she was simply forgotten in the credits. It is revealed in Stitch! that she is indeed Experiment 275 and Wormhole has taken Experiment 272. "Snafu", Stitch!
276 Remmy Green A blue experiment with a huge head that resembles Inky from Pac-Man. He is designed to enter a sleeping person's head and turn dreams into nightmares. If the person wakes up while he is still inside, he will remain there permanently to turn all future dreams into nightmares. Also, 276 was designed to attack at peak of the subconscious enjoyment. His one true place is making Virtual Reality games. His name is in reference to the REMnote  stage of sleep, in which dreams occur. He is voiced by Jeff Bennett. "Remmy", Leroy & Stitch, Stitch!
277 Snooty Red or White A light purple bat-like experiment with a furless, triangle-like body, little legs, two fingers and a thumb on each of his wings, hardly any neck, fanged wide mouth, two little nostrils, pointed ears and black eyes. He is designed to find and enrich "Snootonium," a rare element that becomes extremely dangerous once enriched, which has a similar chemical makeup as that of mucus on Earth. To help clear her sinuses, Lilo's friend Victoria decides to keep Snooty as a pet, as his one true place. Snooty's pod was seen in "Mrs. Hasagawa's Cats", where it was colored white instead of red. "Snooty", Leroy & Stitch
278 Pasthole   Experiment unseen  
279 Futurehole Yellow This experiment's pod was seen in the experiment profiler special feature on the Lilo & Stitch 2: Stitch Has a Glitch DVD. Its function is unknown.

282 Click   Experiment unseen  
283 Quarklifter   Experiment unseen  
284 Pixel   Experiment unseen  
285 Lax Green A purple parrot-like experiment with a small antenna, a beak and tail feathers. He is designed to fire a green ray from his antenna that will cause anything it hits to stop working, and can also climb walls. A person hit by his ray will relax, and a machine hit with the ray will shut down. The ray can be blocked or bounced off reflective surfaces. However, the ray wears off in time. The Recess gang helped Lilo capture 285. His one true place is at the airport, making grouchy business people enjoy their vacation. "Lax", Leroy & Stitch
286 Gellasifier Red This experiment's pod was seen in the experiment profiler special feature on the Lilo & Stitch 2: Stitch Has a Glitch DVD. Its function is unknown.  
287 Burl   Experiment unseen  
288 Boomer Yellow A small white and brown experiment with a curved head and lightweight body. He is designed to be a living boomerang. His one true place is with Mrs. Hasagawa as one of her "cats". "Mrs. Hasagawa's Cats", Leroy & Stitch, Stitch!

297 Shortstuff Green A red-orange crab-like experiment with four claws, four legs, dark blue eyes and two antennae on his head, able to swivel at the waist more than 360°. He is designed to destroy machinery by entering the mechanism and cutting the internal electrical wiring with his claws. His size was greatly increased by accident when he was zapped by Jumba's growth ray. As a result of his growth, his one true place is as an amusement park ride. He is voiced by Nancy Cartwright. He was seen in the Stitch! anime back at his original size. "Shortstuff", Leroy & Stitch, Stitch!

    Sparky (Experiment 221) 
https://static.tvtropes.org/pmwiki/pub/images/sparky_experiment_221.png
Voiced by: Frank Welker, Steve Blum (Stitch!)
Debuted in: Stitch! The Movie

A yellow Chinese-style dragon/monkey/gecko-like experiment with electrical powers, and the first experiment to be reactivated following the creation of Stitch. He can cause electrical outages when using his powers. The first experiment that Lilo and Stitch turned from bad to good, his "one true place" is powering the old Kīlauea Lighthouse as it was deactivated for a number of years due to it having become too expensive to keep it running.


  • Adaptational Villainy: In the video game, Kingdom Hearts: Birth by Sleep, where he is a mandatory boss battle. Justified though as the game takes place at a time before the events of Lilo & Stitch, so he was still evil by then.
  • Ascended Extra: One of the more prominent experiments, eventually becoming the first of Stitch's cousins to appear in a Disney work outside of the Lilo & Stitch franchise. By extension, he is also the only Disney television character to appear in a Kingdom Hearts game so far. He has also made several appearances in the anime due to his popularity.
  • Big Damn Heroes: Gets several in Stitch! The Movie (see The Movie's page for more details on this trope).
  • Psycho Electro: An electric being that has a good bit of the mischievous personality that Stitch has, down to having his own Evil Laugh. It must run in their family.
  • Retractable Appendages: Has an extra pair of arms like Stitch, though he doesn't use them much. However, his first showing of his extra arms plays a role to Stitch accepting him as a cousin.
  • Ride the Lightning: He can travel through electrical currents and can fly through the air. This also changes his appearance, with the lower half of his body expanding to appear as a long electric streak.
  • Shock and Awe: His main ability and the basis for his name.
  • Small Role, Big Impact: While not exactly a minor character, Sparky's appearances in Lilo & Stitch: The Series are only occasional. However, his actions during Stitch! The Movie are the reason for why Gantu and Reuben (625) spend the series stranded on Earth in a spaceship too damaged to fly, preventing them from leaving even if they wanted to.
  • Weaksauce Weakness: A simple glass vase can trap him since glass is not conducive to electricity.

Description Appearances
300 Spooky Green A ghostly green blob-like experiment with olive green eyes, a wide mouth and three round, short, stubby spikes on his back, greatly resembling another Disney (and Halloween-based) character, Oogie Boogie. He is designed to scare people by morphing/shapeshifting into their worst horrifying fears. He appears during Halloween. His one true place is as a greeter for Trick-or-Treaters during Halloween, and at an old house believed to be haunted during the rest of the year. "Spooky", "The Asteroid", "Checkers", Leroy & Stitch, Stitch!, Lilo & Stitch 2: Hämsterviel Havoc
301 Progno   Experiment unseen  
302 Noidster   Experiment unseen  
303 Amnesio Yellow A small blue beetle-like experiment with a round body, two thick arms, two thick legs, a purple mark on his stomach, two large wings on his back, a round face with large black eyes, a little mouth, and two antennae. He is designed to erase people's memory by zapping a red laser beam into their eyes. The password "ʻohana" must be spoken to reverse its effects.note  He was given to Dr. Hämsterviel, who promptly lost his memory. He was rescued in "Snafu" and his one true place is helping restore people's memories. He appeared in the Stitch! anime, where it is discovered that when he erases memories, he stores them in pouches under his wings. If the person ingests the right pouch, his/her memory will return. However, only Amnesio knows whose memory belongs to whom. He is voiced by Tress MacNeille. "Amnesio", "Woops", "Snafu", Leroy & Stitch, Stitch!
304 Drag   Experiment unseen  
305 Spunky Purple This experiment's pod was seen in the experiment profiler special feature on the Lilo & Stitch 2: Stitch Has a Glitch DVD. Its function is unknown.

314 Jones   Experiment unseen  
315 Chum   Experiment unseen  
316 Morpholomew Yellow A small red blob-like experiment with two arms, two legs, a thin mouth and dark eyes. He is designed to morph organisms into any other organism, after seeing the target organism or a photo of the target organism at least once before. However, someone who has been morphed keeps the same voice and needs this experiment to change back. He is known to love chicken legs. His one true place is at a costume store, temporarily transforming people into the person or character of their choice. Jake Long (when in his dragon form) was mistaken for this experiment by Gantu. One of Jake Long's friends, Spud, gave Morpholomew his name when it was agreed that Lilo's name for this experiment ("Changer") was not interesting enough. He later appeared in the Stitch! anime episode "Lilo" where he was modified by Hämsterviel to morph his own body instead of others and gained the ability to speak English. "Morpholomew", Leroy & Stitch, Stitch!
317 Hyuckster   Experiment unseen  
318 Chortle   Experiment unseen  
319 Spike Yellow A large dark blue porcupine-like experiment, with large white-tipped spines on his tail, back, front legs and head, a red nose, large black eyes, and black claws. He can throw the spines on his long tail like darts. He is designed to make 99% of the population silly and useless by pricking them with his spines, leaving only 1% of the population clever (which Jumba used to explain why he never got hurt by one of Spike's quills). When Lilo discovers Mertle cheating in a contest by getting the answers from Teresa, she uses Spike on Teresa to have her give Mertle completely silly answers. Despite his initially grouchy demeanor, Spike is actually very affectionate, and his one true place is hugging—and thus taming—truant experiments at Pleakley's E.A.R.W.A.X. group, after he is given protective armor to cover his silliness-inducing spines. "Spike", Leroy & Stitch, Stitch!
320 Cloudy White A grey cloud-like experiment who is designed to depress others with constant rain. His one true place is raining on Mrs. Hasagawa's fruit, thus keeping them fresh longer. Leroy & Stitch
321 Lightfoot   Experiment unseen  
322 Heckler Red An orange experiment with short pointed ears, small beady eyes, large fangs, and a shirt and bowtie imprint on his body. He is designed to verbally insult people by appearance and personality. His insults can be defused by accepting that they are true. His one true place is sitting over a dunk tank where he provokes people to try and dunk him. He is voiced by Will Sasso. "Heckler", Leroy & Stitch
323 Hunkahunka White A small pink/purple hummingbird-like experiment who is designed to peck people, making them artificially fall in love with the first person they see. The effect is reversed by being sprayed with water. Named after a lyric in the Elvis Presley song "Burning Love", Lilo refers to him as a "Hunkahunka bird of love." He was given to Dr. Hämsterviel, who "fell in love with" Gantu after being pecked (although Hämsterviel still insulted Gantu like he would on a regular basis). He was rescued in "Snafu", and his one true place is in a heart-shaped birdhouse working on an online dating service. "Hunkahunka", "Snafu", Leroy & Stitch, Stitch!

340 Nodessertro (a.k.a. Whatsisname) White An experiment designed to cause mass depression by stealing puddings, cakes, pies, and other sweets. His name is often forgotten, and so he is called "Whatsisname". He was technically kidnapped by Gantu shortly before the events of "Amnesio", but was not seen when the other kidnapped experiments were rescued in "Snafu". A small, green mole-like experiment with a long rat-like tail that was seen in Leroy & Stitch is believed to be this experiment. Leroy & Stitch (supposedly)
341 Wafty   Experiment unseen  
342 Greensleeves   Experiment unseen  
343 Chaching   Experiment unseen  
344 Dupe Yellow A small, gold, monkey/lemur-like experiment with relatively flat ears, a brown-striped tail, and brown-striped prehensile appendage protruding from his head. He able to generate clones with the appendage on his head. However, the traits and abilities of the cloned object become divided amongst the original and the clones; in other words, each duplicate is not as powerful as the original. He also has a reverse function that can revert all duplicates back into the original. His one true place is copying shave ice cones, making them low-calorie. He is voiced by Tara Strong. In the Stitch! anime, he was modified by Hämsterviel so that every duplicate the experiment makes is actually stronger than the original. "Dupe", "Remmy", "Snafu", Leroy & Stitch, Stitch!
345 Elastico Green A green, furless, earless, clownish, roughly monkey-like creature with no tail, a large red round clown nose, white face and stomach, wide mouth, black eyes, neck frill, three huge tendrils on his head that resemble a jester's cap, and a purple spot on his stomach. He is designed to distract enemies by performing tricks with his highly elastic body. He is found already activated and in his one true place: the circus. "Elastico", "Checkers", "Remmy", Leroy & Stitch, Stitch!
346 Stuckup   Experiment unseen  
347 Slobber Blue A green lizard/snake-like experiment with an antenna on the back of his head who stands on two legs. He appeared in some Disney Adventures comics set before the original film. The events of these comics appear to have been retconned, although he could still have the same physical appearance. He dribbles drool downward from his mouth. Disney Adventures
348 Snappish   Experiment unseen

354 Jesstifer Red This experiment is named after The Series' executive producer and writer Jess Winfield's username on TVTome/TV.com. Its function is unknown.  
355 Swapper Blue A two-headed, four-armed green lizard-like experiment who is designed to switch people's minds. Only he can undo the switch. Lilo and Stitch tame Swapper, but his one true place is not revealed. In Leroy & Stitch, he is shown playing keyboard during the impromptu "Aloha 'Oe" concert. "Swapper", Leroy & Stitch, Stitch!
356 Rippington   Experiment unseen  
357 Downes   Experiment unseen  
358 Manners  A black and white penguin/orca-like experiment that acts like a doorman or butler. He is designed to make people too polite to fight back against bullies by sprinkling a special dust from his finger onto them. His one true place is with Mrs. Hasagawa as one of her "cats". He is one of the few experiments that can speak English. "Mrs. Hasagawa's Cats", Leroy & Stitch
359 Phoebe   Experiment unseen  
360 Drowsy Yellow A gray sheep-like experiment with striped ears and that can walk on its hind legs. He is designed to put people to sleep by bleating, although the effect is near-permanent. The surest way to reverse this experiment's effect is with a splash of water. Lilo put Stitch to sleep with Drowsy in order to release PJ (133), but Stitch managed to wake up on his own. Drowsy's one true place is putting insomniacs to sleep. "Drowsy", "PJ", "Ploot", "Remmy", Leroy & Stitch

375 Phantasmo Yellow A green phantom-like experiment with short arms, a large conehead with two stripes, a squeaky voice, a koala-like face, long rabbit-like ears, and dark pupil-less eyes. He is able to possess inanimate objects and bring them to life. Being a ghostlike experiment, he can also travel through weapons and materials typically used to capture experiments, such as nets and bottles which can keep experiments under containment. His one true place is at the Macky Macaw's restaurant, possessing the robotic body of the animatronic Macky Macaw that was previously out of order. He is voiced by Nancy Cartwright. "Phantasmo", Leroy & Stitch

He is able to hypnotize anyone into obeying the next command that person hears. The effect can be undone by snapping one's fingers. His one true place is hypnotizing people at children's parties, causing the hypnotized person to act silly to provide harmless entertainment. "Swirly", "The Asteroid", Leroy & Stitch, Stitch!

397 Spats Yellow A small yellow squirrel/cat-like experiment with orange markings on his back, small pointed antennae, a catlike face, pointed fangs, a green tongue, orange spots on his forehead and two prongs on the end of his long bushy tail, seen when it is unfurled. He is designed to make individuals fight with each other by zapping them with a beam fired from the ends of his tail. The cure for this is to stop and count to ten. His one true place is in Wizard Kelly's professional wrestling show, where Spats can make pro wrestlers fight more convincingly. He is voiced by Frank Welker. "Spats", Leroy & Stitch
398 Gus the Second   Experiment unseen  
399 Super-X   Experiment unseen  

4-Series

By far the series with the least amount of experiments that were seen in the franchise, The Other Wiki (before they deleted their experiment list article) described it as "a mystery series filled by a few annoyances", while TV.com (supposedly quoting from Winfield) says that this experiment series is a "[m]ysterious series of mostly failed experiments, that's why not many are seen."

503 Comet Green This experiment's pod was seen in Stitch! The Movie. Its function is unknown.  
504 Bling Bling   Experiment unseen  
505 Ploot  A small, blue-green, gastropod-like experiment with a small pouch, black beady eyes, green crab-like claws, and two spinning sweeper brushes for feet. He makes dolphin-like sounds at normal size, and monstrous roaring sounds when he has grown to a massive size. He is designed to flood entire cities with thick black sludge made from ordinary trash and pollution that he collects. His two antennae become like giant smoke stacks, emitting clouds of pollution into the air like smog. Air freshener can dissolve his sludge and make him clean instead of pollute. His one true place is cleaning Lahui Beach. In his episode, he is referred to as 515, which is Deforestator's number and who also appears in that episode. The episode this experiment was featured in was first aired on Earth Day. "Ploot", Leroy & Stitch, Stitch!
506 Ug   Experiment unseen  
507 Woody Blue A brown beaver-like experiment with insect-like pincers who is able to eat wood at a rapid pace. His one true place is with Mrs. Hasagawa as one of her "cats". "Mrs. Hasagawa's Cats", Leroy & Stitch, Stitch!
508 Phil   Experiment unseen  
509 Sprout Blue A plant-like experiment with a green stem, leaf-like body, tentacle-like vines, and a purple head with lizard-like face, little sharp teeth, dark blue pupil-less eyes, and a single antenna. He is designed to sprout into an uncontrollable forest of destruction. Lilo entered Sprout in an orchid competition, but the experiment began to grow out of control. Lilo and Stitch ended up catching Sprout after he had grown enormous, and Stitch planted him in an old water tower that was slated for demolition. However, in the battle between the Leroy army and the experiments at the end of Leroy & Stitch, Sprout did not sprout into an uncontrollable forest of destruction as he did on his episode. He is a parody of Audrey II from The Little Shop of Horrors, and is voiced by Frank Welker. In the Stitch! anime, it's revealed that he can also produce seed pods and launch them into space. One of these pods landed on Izayoi Island and was activated as Sproutling (509-A), who had his father's original programming. The original Sprout did reappear in the anime under Hämsterviel's control. "Sprout", Leroy & Stitch, Stitch!

530 Crybaby   Experiment unseen  
531 Hisee  A green mole/chimp-like experiment with six hairs on his head, a very small body and a stubby tail. He appeared in some Disney Adventures comics set before the original film. The events of these comics appear to have been retconned. However, he could still have the same physical appearance. His function is unknown. Disney Adventures
532 Strata  This experiment was mentioned in "Skip" when Gantu said, "The one with that thing that goes bzzz." Its function is unknown.  
533 Blowhard Blue A purple anteater-like experiment with an elephant-like head with a long trunk and a bellows on the back of his head.

    Yin & Yang (Experiments 501 & 502) 
https://static.tvtropes.org/pmwiki/pub/images/yin_and_yang_experiment_501_and_502.png
Yin (501) on the left and Yang (502) on the right.
Both voiced by: Frank Welker
Debuted in: "Yin-Yang" (Lilo & Stitch: The Series Season 1, Episode 5)

An experiment duo who were designed for different purposes. Yin is a (supposedly) female teal octopus/squid-like experiment who sprays water at high pressures. Yang is a male orange-red weasel/lizard-like experiment who shoots lava. Their "one true place" are using their abilities together to create a whole new island.


  • Fire/Water Juxtaposition: Well, more like "Lava/Water Juxtaposition" in their case. The majority of their debut episode sets them up that they must never meet or the elemental clash would cause a deadly reaction, but it turns out Opposites Attract and their powers combined can create new landforms. Given that the franchise takes place in Hawaii, this could very well be a reference to the legend of Pele and Na'maka in Hawaiian mythology.
  • Lady Looks Like a Dude: Yin gets referred to as a male by Lilo throughout the experiment's debut, even though Yin is (probably) female.
  • Pink Girl, Blue Boy: Inverted if they are truly of opposite genders; Yin is bluish while Yang is reddish. Justified considering their names.
  • Magma Man: Yang shoots lava through the four volcano-like spouts on his back.
  • Making a Splash: Yin sprays water through her(?) eight hose-like tentacles.
  • Meaningful Name: Named after the famous concept in Taoism, in which water and femininity are represented by yin and fire and masculinity are represented by yang.
  • Meet Cute: Jumba warns that the Earth could be destroyed if Yin and Yang ever meet. They do, and this happens.
  • No Mouth: Yin is often drawn like this, but a few brief scenes in a couple episodes ("Angel" and "Slugger") show that the experiment does indeed have one.
  • Opposites Attract: A (possibly) platonic example. They're fire and water, yet they're pretty much perfect for each other.
  • Platonic Life-Partners: After their debut, they're rarely seen apart.
  • Ship Tease: The Meet Cute mentioned above is a particularly noteworthy case.
  • Sequel Non-Entity: They were among the most recurring experiments in The Series, yet they never appear in an episode of the anime, although Yin is featured in one of the "Kung Fu Dragon Pleakley" segments and can also be seen in one of the theme song animations, while an image of Yang briefly appears on Jumba's computer at one point.

    Richter (Experiment 513) 
https://static.tvtropes.org/pmwiki/pub/images/richter_experiment_513.png
Voiced by: Tress MacNeille
Debuted in: "Richter" (Lilo & Stitch: The Series debut episode)

A purple Ankylosaurus-like experiment designed to cause earthquakes with a slap of his tail. His "one true place" is making milkshakes in the Rental Hut on Lahui Beach.


    Cannonball (Experiment 520) 
https://static.tvtropes.org/pmwiki/pub/images/cannonball_experiment_520.png
Voiced by: Tress MacNeille
Debuted in: "Cannonball" (Lilo & Stitch: The Series Season 1, Episode 7)

A pink experiment with a large posterior who has the ability to create massive tidal waves. His "one true place" is at Lahui Beach generating choice surfing waves.


  • Be the Ball: Like Stitch, he can contort himself into a ball and roll into enemies to attack.
  • 11th-Hour Superpower: He was not shown to have above-mentioned ability until Leroy & Stitch.
  • Giant Wall of Watery Doom: He was designed to cause these, and he makes a few in his episode, including one just for Gantu.
  • Making a Splash: His main ability. He actually has control over his waves, so much that he was able to make a massive wave that sent Gantu (and only Gantu) all the way to San Francisco.note 
  • Ocean Awe: He is naturally attracted to large bodies of water, and will try to dive into them. This played a role along with the above two tropes as to why Lilo and Stitch had to stop him before he reaches the Pacific in his episode.
  • Sequel Non-Entity: He does not show up at all in any episode of the anime despite his several appearances in The Series, although he does appear in a theme song animation.

    Slushy (Experiment 523) 
https://static.tvtropes.org/pmwiki/pub/images/slushy_experiment_523.png
Voiced by: Frank Welker
Debuted in: 'Elastico' (Lilo & Stitch: The Series Season 1, Episode 17)

An icy blue-colored roughly koala-like experiment who has the ability to generate snow and ice. His "one true place" is making Hawaiian shave ice (a frozen dessert similar to a snow cone), with Dupe (Experiment 344) later joining him in making half-calorie shave ice.


  • Adaptational Villainy: He's on Hämsterviel's side in the anime.
  • Elemental Eye Colors: An ice-generating experiment with blue eyes (and body).
  • Healing Factor: He can regenerate himself after being broken into several ice blocks.
  • An Ice Person: His abilities are strong enough to create powerful blizzards, and he can also make weapons out of ice.
  • Mundane Utility: His "one true place" involves using his powers to make a dessert. He also sometimes uses his powers to make snowballs to throw at others.
  • The Rival: To Splodyhead (619), Slushy's opposite in elemental power, where they had an epic fight against one another in Slushy's episode. They resolved their issues with one another in "Spike" during Pleakley's E.A.R.W.A.X. sessions.
  • Series Continuity Error: Even though he had an episode of his own, he appeared a month earlier in "Elastico" where he was shown already rehabilitated.

6-Series

"Battlefield or doomsday experiments with galactic implications." In other words, these are Jumba's most powerful experiments.

Tropes for any of these experiments can be found in either the "General" folder or any of the folders above.

Name Pod
color
Description Appearances
600 Woops Blue A purple, skinny, Stitch-like experiment with huge yellow buckteeth, a football-shaped head with three short white-tipped antennae and a short white-tipped tail. He is designed to be indestructible and able to do anything. He has all the powers of Stitch, but is a total klutz who accidentally bumps into everything. The only thing he can say is "Woops!" His one true place is being a valued member of Pleakley's bowling team, since the one thing he can actually do is knock things over, including bowling pins. He is the first prototype of Stitch and is considered a failure due to his extreme clumsiness. He is voiced by Rob Paulsen. "Woops", Leroy & Stitch
601 Kixx Blue See folder below "Kixx", "The Asteroid", "Houdini", "Angel", "Slugger", "Shoe", "Checkers", "Ploot", "Ace",note  Leroy & Stitch, Stitch!
602 Sinker Blue A small, purple shark-like experiment designed to destroy and sink enemy ships with his large razor-sharp dorsal fin. His one true place is at a Japanese restaurant where he uses his large fin to cut up vegetables and fillet fish for the chefs to make sushi. "Sinker", "Drowsy", "Ploot", Leroy & Stitch, Stitch!, Disney Stitch Jam 2note 
603 Zap Yellow A bright yellow living laser beam-like experiment with lightning-shaped antennae, dark blue eyes, and a small limbless vaguely dog-like body. He was caught by Gantu with the help of Experiment 627 in "627", but was later rescued in "Snafu". "627", "Snafu", Leroy & Stitch, Stitch!
604 Houdini Yellow A whitish-tan rabbit-like experiment with four brown spots on each elbow and knee, pink mark on his chest and stomach, purple markings on his back and ear tips and a little face with a small mouth, dark pink nose, and large round black eyes. He is designed to make anything and himself disappear (become invisible) with a blink of his huge eyes; though he can reverse the invisibility and make the invisible object reappear. His eyes are sensitive to intense light (i.e. camera flashes), which cause him to blink reflexively and randomly make the surrounding objects or creatures he sees invisible. He is easily spooked and skittish and does not like to fight. He is named after Harry Houdini. His one true place is as a Hollywood magician. He is voiced by Rob Paulsen. "Houdini", "Remmy", "Snafu", Leroy & Stitch, Stitch!
605 Warpstron   Experiment unseen  
606 Holio Blue A small, red chipmunk-like experiment with a wide, large mouth, two thin antennae, and three thin back spines. He is designed to create a matter-sucking black hole when he opens his mouth. He is able to retrieve the items he sucked in, returning Mertle's dolls he sucked up to her. His one true place is working in construction sites, clearing up waste by sucking in the unneeded matter. He is voiced by Frank Welker. "Holio", "Checkers", "Ace",note  "Snafu", Leroy & Stitch, Lilo & Stitch 2: Hämsterviel Havoc
607 Launch Blue A tan naked mole-rat-like experiment with four spines on its back. It is designed to warp the fabric of time and space, causing the entire universe to collapse upon itself. This experiment itself never actually appeared in The Series, but it was the pod on the sandcastle in "627". Rufus the naked mole-rat was mistaken for this experiment in the Kim Possible crossover episode named after him until Stitch identified him as not being one of the "cousins".  
608 Slugger Blue A small, yellow pterosaur-like experiment who is designed to deflect projectiles with his tail shaped like a baseball bat. His one true place is as a Little League Baseball coaching assistant. "Slugger", "Glitch", Leroy & Stitch, Stitch!, Lilo & Stitch 2: Hämsterviel Havoc, Disney Stitch Jamnote 
609 Heat Green A small, red-orange vaguely dog-like experiment with small eyes, a big mouth, small drooping ears and a large shiny black oval embedded in his forehead. He is designed to fire rays of flaming heat from the blowtorch-like feature on his forehead. He was found (in pod form), activated, named, and trained by Gantu. This experiment was sent to Dr. Hämsterviel, but was rescued by Lilo and Stitch in "Snafu". "Dupe", "Remmy", "Snafu", Leroy & Stitch, Stitch!
610 Witch  A small, purple bat/ghost-like experiment. The back of her head is shaped like a cone and curved at the bottom to resemble a witch hat, and her ears resemble small bat wings. Her eyes are blue and she has eyelashes. Her stomach is light purple and her chest has a yellow heart. Her witch-like hat head has a pattern of purple and then light purple stripes. She was designed to have many supernatural abilities. These include the abilities of a ghost and being able to possess others in order to turn them into evil witches too. Once possessed, the victim is under Witch's complete control and also has her variety of abilities such as animation, spontaneous generation, levitation, demonic transformation, and other forms of reality-bending abilities. She is voiced by Susanne Blakeslee. Stitch!
611 El Fin (a.k.a. Doomsday) Blue An experiment designed to make the universe implode when Jumba speaks the password. Fortunately, Jumba forgot the password. Called the "ultimate super weapon", Gantu thought that he had this experiment's pod in "Houdini" but he was actually reading 119's pod upside down. His original name was Doomsday, but this was changed due to a copyright issue.  
612 Blandzilla  A large, red dinosaur-like experiment with round spikes down its back and two spines on the back of its head. Its function is unknown. Lilo & Stitch DVD bonus featurenote 
613 Yaarp Yellow A small, cyan lemur-like experiment with short, floppy Drowsy (360)-like ears (but with darker tips instead of stripes), four arms, a long tail with dark blue rings which he uses as a spring to quickly hop from place to place, and a single megaphone-like antenna on his head. He is designed to make a literally deafening sonic blast, unfurling his normally curled-up antenna to emit the blasts. Pleakley was sent out to capture 613 because he lacks ears, which made him immune to the experiment's sonic blasts; Pleakley also befriended and named 613 after saving him from a collapsing cave. Yaarp's one true place is as an "alien invasion alarm" and a buzzer for the hula school. He also operated the scoreboard for the trivia contest in "Spike". He is voiced by Grey DeLisle. "Elastico", "Yaarp", "Spike", "Remmy", Leroy & Stitch, Lilo & Stitch 2: Hämsterviel Havoc
614 Gunner Blue This experiment's pod was seen in the experiment profiler special feature on the Lilo & Stitch 2: Stitch Has a Glitch DVD. Its function is unknown.  
615 Yogee   Experiment unseen  
616 Joey   Experiment unseen  
617 Plasmoid Blue A large green scorpion-like experiment with a pincer-less tail. He is designed to shoot explosive balls of plasma from his tail. Plasmoid was found (in pod form), activated, named, and trained by Gantu. This experiment was sent to Dr. Hämsterviel, but was rescued in "Snafu". "Dupe", "Snafu", Leroy & Stitch, Stitch!
618 Crystallene  Believed to be a tall, bright purple wiener dog-like experiment with long, crossed ears and a large orange nose. An experiment matching this description can be seen in Leroy & Stitch. Leroy & Stitch (supposedly)

628   Blue Created around the same time as 627, it was seen only in pod form at the end of "627" as Jumba locked it away in a vault, saying, "So much for Experiment 627. Perhaps I will have better luck next time." This experiment never physically appeared in the franchise, nor was it mentioned ever again after "627".  
  Leroy   See folder below Leroy & Stitch
  Cyber  Cyber is a villain of the Stitch! anime who was never part of Lilo & Stitch: The Series. In the anime, Experiment Zero, nicknamed "Cyber", was the first experiment created before Jumba started assigning numbers to the other experiments, indicating that he is not part of any series, though he was initially a purple version of Stitch (now black), sharing similarities with experiments of the 6-Series. Jumba created this ultimate killer monster, but the result was overly succeeded. Unable to control the experiment, Jumba eventually suspended him and locked him away on an icy planet. Experiment Zero later escaped and acquired mechanical body parts, which not even Stitch could rival. His one true place is in Galactic Prison. He is voiced in the anime's English dub by Paul St. Peter. Stitch!

    Kixx (Experiment 601)

Voiced by: Frank Welker
Debuted in: "Kixx" (Lilo & Stitch: The Series Season 1, Episode 10)

A purple, muscular Tasmanian Devil-like experiment with four arms who is designed to beat up individuals. His "one true place" is teaching people how to kickbox, and also hosts a series of workout videos called Kickboxing with Kixx.

Debuted in: 'Splodyhead' (Lilo & Stitch: The Series Season 1, Episode 11)

Also known as "Splody" for short, he is a small, red reptilian dragon-like experiment with six legs who fires hot plasma blasts from his lone nostril. His "one true place" is lighting tiki torches at the local luau.


    Chopsuey (Experiment 621) 
https://static.tvtropes.org/pmwiki/pub/images/experiment_621_chopsuey.jpg
Voiced by: Frank Welker
Debuted in: Disney's Stitch: Experiment 626 video game

A skinny, green koala-like experiment who is presumably an earlier prototype of either Stitch or Reuben. He has all of Stitch's abilities but is not as capable as his younger cousin.

Originally, 621 was sent on missions to collect DNA for experiment creation, but Jumba was disappointed with his results. During the events of the PlayStation 2 prequel video game Disney's Stitch: Experiment 626, 626 was given 621's mission and proved himself to Jumba to be better at DNA-collecting than 621. Criticized and neglected by Jumba, 621 then secretly collected DNA for himself and used it to mutate to a larger, stronger form. Unfortunately for him, he was defeated in battle by 626, who tricked 621 into being electrocuted. Gantu promptly arrested Jumba and the two experiments shortly thereafter.

621 never appeared in any part of the franchise outside of the Stitch: Experiment 626 video game, which was retconned by the events of Lilo & Stitch 2: Stitch Has a Glitch. However, in The Series episode "Kixx",note  Jumba mentioned that 621 trained Stitch in the time before his and Stitch's arrest by the Galactic Federation, thus complicating this experiment's canonicity in the franchise. Nevertheless, based on the events of Leroy & Stitch, he was eventually found and captured by Lilo and Stitch at some point before the film and given the name "Chopsuey", though it is not known what his "one true place" is or if he even maintained his original design, function, and abilities.


The Mid Six-Twos

This particular trio of experiments are among the franchise's major characters, and thus receive the most appearances throughout its works and merchandise. They're the closest thing to a Power Trio among the experiments.

    Angel (Experiment 624) 
https://static.tvtropes.org/pmwiki/pub/images/angel_experiment_624_6.png
"Da boojiboo!"

Voiced by: Tara Strong, Kate Higgins (Stitch!)
Debuted in: "Angel" (Lilo & Stitch: The Series Season 1, Episode 30)

A pink, female koala-like experiment and Stitch's Love Interest. She has the ability to convert rehabilitated experiments made before her back to evil by singing a siren song, though it has the reverse effect when said song is sung backwards. She originally worked for Gantu and Hämsterviel, but turned on them after meeting and falling in love with Stitch, so Gantu captured her and took her away in retaliation. She was rescued in "Snafu". In the anime, she became a superstar pop singer.


  • Action Girl: She isn't as limited in capabilities as most of her predecessors. She knows how to fight, as seen when she busted herself, Stitch, and others out in "Snafu", and when she quickly took down four Leroy clones to protect Stitch in Leroy & Stitch.
  • Affectionate Nickname: She and Stitch refer to each other as their "boojiboo", which is a term of endearment meaning "beloved" or "loved one" in their native Tantalog language. Reuben, who was more attracted by her looks, called her "Hotcakes".
  • Alien Hair: Her antennae vaguely resemble long human hair. She can use them like tendrils in lieu of a second pair of arms, but the only time they do something was in her debut episode where she uses one to push an out-of-reach button.
  • Aliens Speaking English: Not in The Series, as she spoke just two non-Tantalog words in "Snafu", but by the time of the anime she's become a fluent English speaker. Justified considering that she probably needed to learn English in order to have her singing appeal to humans.
  • Ascended Extra: As explained below, she went from intended One-Shot Monster of the Week to becoming one of the most prominent characters of the franchise.
  • Becoming the Mask: First pretended to love Stitch and be his new girlfriend, but his sheer kindness and siren song immunity caused her to actually fall in love with him and become his girlfriend.
  • Breakout Character: She was in only two episodesnote  of The Series, one of them being the show's last regular episode, and in Leroy & Stitch she was only in the final battle against the Leroys and in the big family photo at the end. She was also not meant to appear ever again after her debut episode. Despite this, she is one of the most popular experiments that the franchise has introduced, if not the most popular experiment besides Stitch himself, to the point where the anime has featured her much more often. She even has more merchandise than Lilo.
  • Brother–Sister Incest: Although the experiments are referred to as Stitch's "cousins", if one were to actually think about it in technical terms, since Jumba is their creator, it makes him their father.
  • Cute Monster Girl: Not that the other experiments aren't cute themselves, but her Stitch-like body is somewhat more humanlike and we see very few females.
  • Character Development: She originally acted sweet to Stitch simply to sell him out to Hämsterviel, but later does have true affections for him.
  • Damsel in Distress: She's held captive by Gantu for much of The Series after her introduction.
  • Damsel out of Distress: She breaks out of her own containment capsule after Stitch gets himself captured and he confesses his love to her.
  • Defecting for Love: Thanks to Stitch being the first experiment to treat her kindly (helped by the fact that he's immune to her siren song), she ended up feeling guilty for her manipulation of him. As a result, she turned on Gantu and Hämsterviel by reverting the experiments back to good just before the cousins could beat up a weakened and reluctant-to-fight-back Stitch. Unfortunately, this decision did lead to her capture by Gantu at the end of her episode.
  • Distaff Counterpart: To Stitch. The only real differences between them are her color, her antennae and her, um, "V-crest" (that white V-shaped patch of fur on her chest).
  • Dude Magnet: She utilizes this to attract reformed experiments so she can revert them with her singing.
  • Ear Notch: She does not have any. However, some merchandise (even a Funko Pop! vinyl figure of her) do give her Stitch's two asymetrical notches, as if they're too lazy or too cheap to make new molds for her ears. With all that said, there is one pin that does intentionally give her one.
  • Enthralling Siren: Her main ability; she seduces experiments, sings her siren song (lyrics shown below), and they turn to evil.
    Acoota chi-meeto igatta no mootah, nagga to nala itume tidookaTranslation 
  • Evil Diva: Her song itself has evil repercussions. Also, yes, she is a diva.
  • Face of an Angel, Mind of a Demon: At first. This is also the basis for her name, since Lilo named her in sarcasm (see Shout-Out below).
  • Flanderization: Angel actually did have a bit of a diva personality in The Series, but the anime made it a defining aspect of her character and went overboard with it.
  • Heel–Face Revolving Door: While not exhibited by her herself, this is the basis of her primary function, able to invoke a Face–Heel Turn in any experiment made before her (and Jumba) with a song, and can invoke a Heel–Face Turn in the same by singing it backwards.
  • Heel–Face Turn: Used to work for Hämsterviel, but changed sides after realizing her feelings for Stitch.
  • Heroic Sacrifice: In her debut. She was later rescued.
  • Iconic Sequel Character: The most famous of Stitch's predecessors, but it took a long while to achieve this status. She didn't appear at all in the 2002 original film, was only hinted at through a mini-poster and a bonus feature included with 2003's Stitch! The Movie, officially debuted in the thirtieth aired episode of Lilo & Stitch: The Series in January 2004, did not make her only other major appearance in the show until the penultimate aired episode in June 2006, finally became a recurring regular in the Stitch! anime that debuted in 2008 (whose English dub first aired in 2009), and eventually gained a steady stream of merchandise sold worldwide (including the United States, where the anime that she appears most frequently in was rejected) during The New '10s.
  • Ironic Nickname: Initially, although Stitch believed her name to be completely unironic before she actually reformed.
  • Jerk with a Heart of Gold: She may be a bit selfish and snobbish, but she cares for Stitch greatly.
  • Love at First Sight: Subverted at first; she caused this to Stitch, but didn't truly have feelings for him until a day later.
  • Love Redeems: How she was reformed instead of Defeat Means Friendship.
  • Manipulative Editing: Due to her being reformed, Reuben had to trick her into singing to him (he and Stitch are the only experiments unaffected by her singing) so that he could record her voice and play it backwards, turning the experiments tamed by Lilo evil again. Experiment 120 (Snafu) would ruin these plans sometime later.
  • Messy Male, Fancy Female: The Fancy Female to Stitch's Messy Male. Stitch has spiked tufts of fur on his head and chest, while Angel's fur is smooth, with a white V-shaped marking on her chest. In addition, Stitch has notches in his slightly pointed ears and his retractable antennae are short and budded at the tips, while Angel's slightly rounder ears lack notches and her non-retractable antennae are long, curved and smooth with rounded tips.
  • Morality Pet: She quickly establishes herself as Stitch's second one of these (Lilo's the first, obviously) in her debut. He behaves a lot more politely whenever she's around him.
  • My God, What Have I Done?: In her debut episode when Stitch is captured by the experiments that she turned to evil.
  • Off-Model: Besides what's written under Series Continuity Error below, some promotional artwork change her bluish-purple mouth to pink just like Stitch's.
  • Pink Girl, Blue Boy: With Stitch given their fur colors.
  • Pint-Sized Powerhouse: Well, not to the extent of her boyfriend as far as we know, but she is strong enough to break open containment capsules with only a headbutt.
  • Retractable Appendages: Does not seem to have these (her antennae are always exposed and she is too thin at the waist to have the extra arms), but she does have retractable claws. (Pay close attention to her first scene in her debut when she threatens Lilo.)
  • Satellite Love Interest: To an extent, the main reason she was introduced was to give Stitch a love interest.
  • Series Continuity Error:
  • Sequel Non-Entity: Despite that her popularity allowed her to gain more appearances in the anime, this has not followed through with Stitch & Ai.
  • Shout-Out: Her name is most likely a reference to the subject of Elvis Presley's "(You're the) Devil in Disguise", especially since Lilo named her "Angel" as sarcasm.
  • Single Woman Seeks Good Man: Although she did not intend to fall in love with him, Stitch's kindness is what won her over, although he is immune to her siren song. Compare to how she primarily acts around Reuben who behaves more like a sleazeball around her.
  • Story-Breaker Power: Not surprisingly she was Put on a Bus for most of The Series when she can do in one ten-second song what takes Lilo a whole episode. Not so much in the anime, allowing more frequent appearances.
  • Tertiary Sexual Characteristics: She looks like a version of Stitch with a very high-pitched voice, pink fur, long eyelashes, an hourglass figure, a heart-shaped marking on her back, and long antennae that look like hair.
  • Took a Level in Jerkass: In the anime where she gains the personality of a vain, spoiled celebrity (due to becoming a popular singer in the years since Leroy & Stitch) and leaves Stitch for someone else at least three times.

    Reuben (Experiment 625) 
https://static.tvtropes.org/pmwiki/pub/images/reuben_experiment_625.png
Voiced by: Rob Paulsen, Dave Wittenberg (Stitch!)
Debuted in: Stitch! The Movienote 

A chubby, golden-yellow marmot/koala-like experiment who is Jumba's last experiment before Stitch and Gantu's sidekick. He has all the powers of Stitch (plus a much greater English fluency) but is a lazy coward. He makes great sandwiches, though.


  • Adaptation Dye-Job: He's teal-colored in Comic Zone but was changed to golden-colored for the films and TV series.
  • Affably Evil: For an experiment designed to cause massive destruction (not to mention one of Hämsterviel's employees), he's surprisingly laid-back and easygoing.
  • Aliens Speaking English: Unlike his cousin Stitch, he's perfectly fluent in English, speaking it with a Brooklyn accent. This is one of the very few advantages he has over his younger cousin.
  • Appropriated Appellation: After a few attempts he wasn't proud of, he takes to Lilo's last name suggestion, Reuben.
  • Because You Were Nice to Me: Lilo wins him over by naming him and actually befriending him.
  • Big Eater: Mostly of sandwiches.
  • Bookends: He is one of the first experiments to be reactivated since Stitch's creation (which happens in Stitch! The Movie), but the very last one to be rehabilitated and named (which happens in Leroy & Stitch).
  • Brilliant, but Lazy: He has all of Stitch's abilities, including super-intelligence, but not the motivation. Some episodes do show how clever he really is, such as figuring out Experiment 627's Achilles' Heel just by noticing his heavy laughter.
  • Bullying a Dragon: Often insults and otherwise antagonizes Gantu, who dwarfs him in size and is armed. Since 625 lacks the motivation to use his Stitch-like strength, he is thus often fried by a blaster or stomped on.
  • Canon Immigrant: He originally appeared (with teal fur, pupils, and a collar) in a series of Disney Adventures Comic Zone Prequels to the first movie.
  • Deadpan Snarker: One of his main functions.
  • Deuteragonist: In Leroy & Stitch, where he gets his Heel–Face Turn thanks to Gantu abandoning him and Lilo giving him a name. He helps her out in rescuing Stitch, Jumba, and Pleakley after they find out that the experiment they were talking to was not Stitch at all.
  • Flawed Prototype: To Stitch. He has all the same powers and abilities as Stitch, but he's also extremely lazy and an incredible coward.
  • Freudian Excuse: He claims in the Grand Finale the only reason he worked against Lilo and Stitch is because Lilo never bothered to try to help or even name him.
  • Friendly Enemy: Arguably towards Lilo and Stitch when he was one of their enemies in The Series, and had helped them out on occasions, although it's likely due to not caring to actually fight them.
  • Heel–Face Turn: In Leroy & Stitch after Gantu sets out on a small, two-man ship to break Hämsterviel out of prison (the second spot being for Hämsterviel), and leaves Reuben stranded on Earth.
  • Heterosexual Life-Partners: With Gantu; even at the end of Leroy & Stitch, he reconciles with Gantu and finds his one true place as Gantu's first mate and galley cook.
  • Iconic Sequel Character: Although dwarfed in popularity by his immediate successor and predecessor, he is one of the major characters of the franchise and the most often seen experiment in the canon besides Stitch himself.
  • The Imp: He is just as powerful as Stitch, but he is never a real threat. He just spends most of his time making wisecracks (and sandwiches) and eating.
  • Informed Ability: A justified version: it has been stated that he has all the same powers as Stitch, but he is never seen using them because, from the start, Jumba explains that he's also a lazy coward. Finally ended in Leroy & Stitch, when Lilo finally convinces him to get off his lazy patookie and do something for himself.
  • Irony: He was in his one true place all along: by Gantu's side.
  • Lazy Bum: He'll get around to helping Gantu in the field once he's done eating sandwiches and watching TV.
  • The Load: Only useful when it comes to sandwiches. Everything else? Ha ha, no.
  • Lovable Coward: He's absolutely useless as a sidekick.
  • No Name Given: He had this status (regarding names other than his experiment number) until he was named "Reuben" in Leroy & Stitch, although he was called "Sandwich Boy" by Lilo once in the episode "627".
  • Redemption Promotion: Once he decides to stop being lazy and help Lilo, he actually proves himself to be quite useful much like his successor. He even manages to repair Gantu's ship, which Gantu himself was incapable of doing.
  • Retractable Appendages: Revealed in Leroy & Stitch that he does have a lower pair of arms much like Stitch. Before that, an episode of The Series also reveals that he does have retractable claws.
  • Satiating Sandwich: Loves making these and is incredibly good at doing so, to the point that he was named after one.
  • Sequel Non-Entity: Despite his regular appearances throughout the first two TV shows, he does not show up in Stitch & Ai whatsoever. Not even for a cameo.
  • Shout-Out: To J. Wellington Wimpy from Popeye or Jughead Jones from Archie Comics; they're all big eaters, cowardly, lazy, and they often exhibit great technical prowess and a high level of competence. Even Jumba mentions, "Funny thing, 625 has all powers of 626, even has advanced language programming; unfortunately, he is also lazy coward, heh heh heh, but makes great sandwiches."
  • Supreme Chef: Reuben loves making sandwiches and they prove to be very delicious. The problem is that he is obsessed with making them due to his programming from Jumba.
  • Took a Level in Badass: In Leroy & Stitch.
  • Trademark Favorite Food: Sandwiches; he loves anything that can be placed between two slices of bread.
  • Tuft of Head Fur: Subverted; those three things on his head that look like fluffy fur are actually really short antennae. Still, that didn't stop the Japanese from making them into an actual tuft of fur in an episode of the anime.
  • Vitriolic Best Buds: With Gantu.
  • You Are Number 6: He remained number 625 through The Series up until Leroy & Stitch, when he was given the name "Reuben" by Lilo.

    Stitch (Experiment 626) 
Voiced by: Chris Sanders, Ben Diskin (Stitch!, Stitch & Ai)
Debuted in: Lilo & Stitch

A blue koala-like experiment who was designed to "destroy everything he touches", but ended up defying his programmed function after being adopted by Lilo Pelekai as her pet "dog". He is The Protagonist of the franchise.

See the characters sheet for the title characters for tropes and more information.

After Stitch (626)

Stitch's younger, tougher, eviler "cousins" who were not listed in the list of experiments seen in the credits of Leroy & Stitch.

    Experiment 627 
https://static.tvtropes.org/pmwiki/pub/images/experiment_627.png
Voiced by: Chris Sanders, Ben Diskin (Stitch!)
Debuted in: '627' (Lilo & Stitch: The Series Season 1, Episode 19)

Jumba's first experiment made using the limited technology he has on Earth. He activated this experiment after Stitch became egotistical from beating his experiment catching record. 627 is more powerful than Stitch without any of the same weaknesses, and is so evil that he cannot be rehabilitated. Thus, he has no "one true place", and was dehydrated back into a pod at the end of his episode.


  • Achilles' Heel: His laughter.
  • Always Someone Better: He is the evolution of Stitch; greater strength, higher intelligence, fewer weaknesses, and more powers than ever before.
  • Big Little Brother: Well, "cousin", but still 627 is taller and younger than Stitch.
  • Black Eyes of Evil: Oh, yes.
  • The Bully: Really what his personality is in general. He could kill anything he pleases but doesn't because he finds torturing others more fun.
  • Combo Platter Powers: He has the abilities of many other experiments, not just having improved versions of Stitch's powers.
  • Ear Notch: One on each ear like Stitch, but they are symmetrical to one another near the tip.
  • Evil Counterpart/The Rival: To Stitch.
  • Evil Laugh: Has a lower-pitched one in comparison to Stitch's.
  • For the Evulz: He loves demoralizing others, to the point that he will even ruin bad moments just because he can.
  • Giggling Villain/The Hyena: Laughs a lot, and has a twisted sense of humor. However, his laughter is also his Achilles' Heel; he goes into cataplexy and will collapse if he laughs uncontrollably.
  • Good Colors, Evil Colors: He is red and evil, although Jumba actually chose the color to match with the tones found on Earth's creatures.
  • The Juggernaut: Good grief, when he gave Stitch a No-Holds-Barred Beatdown...
  • Heel–Face Turn: Jumba designed 627 to defy this trope, making it impossible to rehabilitate him. Doesn't stop him from sort of doing so in the anime.
  • Multiple Head Case: He has a retractable second head.
  • My Brain Is Big: He has a large, cone-shaped head (two, in fact) to match with his higher intelligence.
  • Nested Mouths: He can extend his jaws (with the tongue inside) out from his mouth.
  • Nigh Invulnerable: Most likely more so than Stitch.
  • No Name Given: Since he could not be rehabilitated, Lilo never named him.
  • Olympus Mons: The most powerful experiment that Jumba ever created.
  • One-Shot Character: The only other appearances this experiment made in The Series was a cameo in Lilo's dream in "Remmy" (which is also the only time he is seen as "good") and the reusage of footage from his original appearance in "Ace". He would appear again in the anime, but it too became a one-time appearance within that show, although he does appear in this High School Musical parody video based on the anime as well (again, seen as "good").
  • One-Word Vocabulary: The only word he could say was "evil", leading to a Fan Nickname for him. He would gain a greatly expanded vocabulary in the anime.
  • The Only One Allowed to Defeat You: In the anime, he tells Stitch this after saving his and Angel's lives.
  • Retractable Appendages: Has more of these than Stitch; he can gain four extra arms instead of just two, four spines (compared to Stitch's three) and another head, with each head having their own retractable antennae.
  • Smug Super: In his original appearance, he tortured Stitch with a No-Holds-Barred Beatdown rather than just killing him, just to prove that he is better in every way.
  • Superpower Lottery: Not only does he have improved versions of Stitch's powers, but he has a lot of powers that some other experiments have as well. And then some.
  • Villain Respect: To Gantu in The Series, judging by how easily he tends to obey him. It could be that 627 was intrigued by Gantu's ambitions.
  • Wicked Cultured: In his anime appearance, where he even gains a greater vocabulary.
  • You Are Number 6: He is the only activated experiment who retains his experiment number as a name. (Note that Experiment 628 was never activated, although Leroy below is sometimes promoted as being 628.)

    Leroy 
https://static.tvtropes.org/pmwiki/pub/images/629___leroy.gif
Voiced by: Chris Sanders
Debuted in: Leroy & Stitch

An evil version of Stitch created by Jumba, under orders of Hämsterviel. He's currently Jumba's latest experiment, though he is not officially numbered.


  • Conservation of Ninjutsu: Subverted; although this trope seemed like it would come into play during the climatic fight against the experiments, the Leroy army actually gained the upper hand until Lilo, Stitch and Reuben started performing "Aloha ʻOe".
  • Evil Counterpart: To Stitch.
  • Evil Doppelgänger: Not only does he looks like a red Stitch, he can shapeshift somewhat to perfectly resemble him.
  • Evil Twin: The Other Wiki and some official promotional descriptions for his film describes him as this towards Stitch, since they have identical powers and Leroy was made so that Hämsterviel would have his own version of Stitch. Thus, it could be that Leroy is Stitch's only actual brother.
  • Flat Character: Being Stitch's Evil Counterpart is all there is to Leroy, as despite the fact that he is one of the main antagonists of Leroy & Stitch, he does not get any character development. You could almost take him out of the movie and replace him with Stitch clones, since he doesn't contribute much despite sharing the title with Stitch.
  • Flight, Strength, Heart: All of Stitch's powers, plus he can instantly regrow his fur and change colors.
  • Good Colors, Evil Colors: He's a red, unreformed Stitch. Hämsterviel deliberately wanted Leroy colored red, because one, he hates the color blue, and two, he wanted an experiment that matches his red cape.
  • Ironic Name: Leroy's name means "King" or "The King" in French. His one weakness is "Aloha ʻOe", a song covered by Elvis Presley and programmed into him specifically through one of his records.
  • Me's a Crowd: Mass-produced by Hämsterviel soon after his creation.
  • Mooks: Leroy is a mass-produced version of Stitch.
  • No Name Given: Inverted; he was named by Hämsterviel, but not numbered. Jumba tried to number him 627, but Gantu reminded him that he already made Experiment 627. Most fans give Leroy the number 629, while some Japanese and Disneyland Paris merchandise give him the number 628. (Except that there was already an Experiment 628 made, too, but no one in the franchise knows that besides Jumba, who's likely also forgotten about 628.)
  • One-Shot Character: Appeared only in Leroy & Stitch.
  • Paper-Thin Disguise: Played with. He looks exactly like Stitch when he turns blue, but can't really pull off the act.
  • Technically a Smile: When he was disguised as Stitch during Lilo's video call, he fakes a smile. Considering that Stitch's teeth are not the best to look at, Leroy's "smile" comes across as really disturbing.
  • Theme Music Power-Up: Inverted; as a fail-safe added by Jumba, if Leroy hears "Aloha ʻOe", he will shut down. This also applies to his clones.
