Characters / Lilo & Stitch - Experiments: 0-Series

Go To

The first ninety-nine experiments are Jumba's test batch, which includes many household helpers.

Although Cyber (X-000) is technically not part of this series—since he predates Jumba's numbering scheme and isn't seen in Leroy & Stitch's experiments list—he is placed on this page for the sake of convenience.

    List of 0-Series experiments 
Tropes for any of these experiments can be found in either the "General" folder back on the main Experiments page or in the folders below this list.

  • X-000: 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. 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. (Appearance: Stitch!)
  • X-001: Shrink — 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 pod is red. 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. (Appearances: Leroy & Stitch, Stitch!)
  • X-002: Doubledip — 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. (Appearances: "Mrs. Hasagawa's Cats", Leroy & Stitch)
  • X-003: Howcome
  • X-004: Squawk
  • X-005: Truxx
  • X-006: Percy
  • X-007: Gigi (a.k.a. "Yapper") — See folder below (Appearances: "Yapper", "Amnesio", "PJ", Leroy & Stitch, Disney Tsum Tsumnote )
  • X-008: Carmine
  • X-009: Pop — 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. (Appearance: Stitch!)
  • X-010: Felix/Oscar — See folder below (Appearances: "Felix", "Remmy", "Woops", "Snafu", Leroy & Stitch, Stitch!, Disney Stitch Jam)
  • X-011: Inkstain
  • X-012: Antitherm
  • X-013: Furry
  • X-014: Kernel — 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. (Appearance: Leroy & Stitch)
  • X-015: Ruggles
  • X-016: Matt
  • X-017: Lidds
  • X-018: Puck
  • X-019: Clumsy — This experiment's white pod was seen in Stitch! The Movie. The pod read 19 instead of 019. Its function is unknown.
  • X-020: Slick — 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. (Appearances: "Slick", "Ploot", Leroy & Stitch)
  • X-021: Twang — Experiment 145, a.k.a. Bragg or Flute, was misnumbered as 021 in the Japanese original, where he was named "Bragg". This led to some official material referring to him as "Twang". The English dub corrected his number to 145, but changed his name entirely to "Flute". That said, supposedly, Jess Winfield has stated that some of Twang's DNA was reused when Bragg was created, which is probably why the experiment plays the flute.
  • X-022: Hertz Donut — 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. His pod is red. (Appearance: Stitch!)
  • X-023: Cyclo
  • X-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?"
  • X-025: Topper — 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 pod is white and his number refers to Christmas Day (December 25). He is voiced by Tress MacNeille. (Appearances: "Elastico", "Topper", Leroy & Stitch, Stitch!, Disney Stitch Jam 2note )
  • X-026: Pawn
  • X-027: Plushy
  • X-028: Lori
  • X-029: Checkers — 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. His pod is yellow. He is voiced by Frank Welker. (Appearances: "Checkers", Leroy & Stitch, Stitch!)
  • X-030: Vialet
  • X-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". (Appearances: "Mrs. Hasagawa's Cats", Leroy & Stitch)
  • X-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; Jess Winfield would later claim that "Spike" takes place after "Snafu" to cover up the production error. He is voiced by Jeff Bennett. (Appearances: "Fibber", "Spike", "Remmy", "Woops", "Snafu", Leroy & Stitch)
  • X-033: Hammerface (a.k.a. "Hammerhead") — 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"; his appearance in that episode is a production error since he was newly found by Gantu in "Dupe" and was rescued in "Snafu". (Appearances: "The Asteroid", "Dupe", "Remmy", "Woops", "Snafu", Leroy & Stitch)
  • X-034: Splort
  • X-035: Philip
  • X-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. (Appearances: "Shoe", "Remmy", Leroy & Stitch)
  • X-037: Snipper
  • X-038: Plats
  • X-039: Atlas
  • X-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 & Not Breakfast". (Appearances: "Shoe", "Checkers", "Remmy", Leroy & Stitch, Disney Stitch Jam 2note )
  • X-041: Kitsch
  • X-042: Itch
  • X-043: Cubesteak
  • X-044: Forehead — 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). He refers to himself with the pronoun "we" instead of "I" or "me", suggesting that each head has its own consciousness. His one true place is with Mrs. Hasagawa as one of her "cats". His pod is green. He is voiced by Rob Paulsen. (Appearances: "Mrs. Hasagawa's Cats", Leroy & Stitch)
  • X-045: Melvin
  • X-046: Wedgie
  • X-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. His pod is green. (Appearance: Stitch!)
  • X-048: Echo
  • X-049: Picker — This experiment's white pod was seen in Stitch! The Movie. The pod read 49 instead of 049, possibly due to the viewing angle. Its function is unknown.
  • X-050: Dunk
  • X-051: Hocker — 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." His pod is green. (Appearances: "Mrs. Hasagawa's Cats", Leroy & Stitch)
  • X-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. (Appearance: Comic Zone: Lilo & Stitch)
  • X-053: Whine
  • X-054: Fudgy — 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. The misnumbered pod in The Series was blue, while the corrected pod in the anime was red. (Appearances: "Houdini", "Snafu", Stitch!)
  • X-055: Snarfhonk
  • X-056: Nibbiolo
  • X-057: Tenderizer
  • X-058: Shortsheet
  • X-059: Tornette
  • X-060: Plink
  • X-061: Anachronator
  • X-062: Frenchfry — 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. His pod is white. He is voiced by Rob Paulsen. (Appearances: "Frenchfry", "Remmy", Leroy & Stitch, Stitch!)
  • X-063: Pufferizer
  • X-064: Nappifier
  • X-065: Britfood
  • X-066: Glam
  • X-067: Shady
  • X-068: Tom
  • X-069: H. T.
  • X-070: Flopjack — This experiment's white pod was seen in Stitch! The Movie. The pod read 70 instead of 070. Its function is unknown.
  • X-071: Penny — This experiment's yellow pod was seen in Stitch! The Movie. The pod read 71 instead of 071. Its function is unknown.
  • X-072: Stickystuck
  • X-073: Cornerpiece
  • X-074: Welco — 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 white pod was seen in Stitch! The Movie, where the pod read 74 instead of 074. (Appearance: Stitch!)
  • X-075: WooWoo
  • X-076: Bath Matt
  • X-077: Zawp — A fat, purple, Nosy (X-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". (Appearances: "Mrs. Hasagawa's Cats", Leroy & Stitch)
  • X-078: Snozzle — This experiment's white pod was seen in Stitch! The Movie. The pod read 78 instead of 078. Its function is unknown.
  • X-079: Fogger
  • X-080: Dan
  • X-081: Backscratcher
  • X-082: Plunge — This experiment's white pod was seen in Stitch! The Movie. The pod read 82 instead of 082. Its function is unknown.
  • X-083: Grimple
  • X-084: Subwoof
  • X-085: Screwup
  • X-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 where Hämsterviel ruled Earth, Lilo, Stitch, and Skip encountered Clink in the possession of Hämsterviel. (Appearance: "Skip")
  • X-087: Puddles
  • X-088: Decrisper
  • X-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, allowing Dr. Hämsterviel to conquer and rule Earth. (Appearances: "Skip", Leroy & Stitch)
  • X-090: Fetchit — This experiment was activated alongside Mrs. Hasagawa's "cats" in the episode of the same name. Its function is unknown.

  • X-097: Dogalarm
  • X-098: Cooper
  • X-099: Spot — A spotlight experiment that was supposed to be in "Spike" but was removed, and was supposed to appear later.

Notable 0-Series experiments

    Gigi a.k.a. Yapper (Experiment 007)
Voiced by: Frank Welker (vocals), Tress MacNeille (speaking)
Pod color: Unknown
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 and Hämsterviel would definitely not have any use for her lackluster abilities.
  • Shout-Out: She has the number of a famous secret agent, although it's most likely coincidental. That being said, she is an alien who is secretly disguised as a dog.
  • 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") and is mentioned in "Tank" before reappearing in Leroy & Stitch. She was even absent when Mertle adopted Hämsterviel in one episode.

    Felix (Experiment 010)
Voiced by: Tress MacNeille, Steve Blum (Stitch!)
Pod color: Unknown
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".
