    Jumba's Experiments

    Concept »

    Genetically engineered aliens who were created by Dr. Jumba Jookiba in Disney's "Lilo & Stitch" franchise. There are over 629 of them, including the famous Experiment 626, also known as Stitch, who thanks to Lilo Pelekai's influence calls his fellow experiments "cousins" after Hawaiian terminology.

    Short summary describing this concept.

    Jumba's Experiments last edited by videogamerkc on 08/03/23 03:05AM View full history


    The genetic experiments created by Dr. Jumba Jookiba are a large group of genetically engineered alien lifeforms in Disney's Lilo & Stitch franchise. Dr. Jumba created them in his laboratory at "Galaxy Defense Industries", most of them with the shady financing of his former lab partner Dr. Jacques von Hämsterviel. Many of the creatures were designed for evil, mischievous, and destructive purposes, though how "evil" they act tends to vary. There are at least 629 experiments, the most famous of which is Experiment 626, better known as Stitch, who is the franchise's primary protagonist.

    The experiments other than Stitch first appeared in prequel spin-off material that was released before the 2002 original film, including the PlayStation 2 game Disney's Stitch: Experiment 626. Although technically every Lilo & Stitch work features at least one experiment—mainly Stitch—they were not a major focus of the franchise until Stitch! The Movie, the 2003 direct-to-video pilot to Lilo & Stitch: The Series. Additionally, the 2017 Chinese animated television spin-off Stitch & Ai excludes all of the original experiments apart from Stitch and instead introduces brand new ones based on Chinese mythological creatures.

    In the first television series, Stitch and his best friend Lilo Pelekai hunt down the experiments, who were scattered around Kauai as dehydrated pods thanks to the events of the pilot. The pods activate when they come into contact with water. When the duo captures and tames an experiment, Lilo gives them a name, and they find a "one true place" (i.e. occupation) where the experiment can use its abilities for productive purposes.

    Stitch, inspired by Hawaiian terminology, refers to nearly all his fellow experiments as his "cousins" and sees them all as part of his 'ohana, or extended family.

    List of experiments seen in games

    Each experiment's number is usually pronounced as individual digits (e.g. "Six-Two-Six" instead of "Six Hundred [and] Twenty Six"), with the only known exceptions being those whose numbers are divisible by 100 (such as X-300/Spooky and X-600/Woops), whose numbers are pronounced as whole numbers, and X-619/Splodyhead, whose number was pronounced as "Six Nineteen" by Jumba. The official shorthand prefix for "Experiment" is "X-" (X with a hyphen), according to several episodes of The Series and the 2004–2018 Walt Disney World attraction Stitch's Great Escape!. All the first 626 experiments' names were fully revealed in The Series's finale film, Leroy & Stitch.

    Since it would take a long while to list all of the experiments here, especially since the large majority of them remain unseen in the franchise to this day, only the experiments who appear in video games are listed here. Fandom's Lilo & Stitch Wiki features a full list of experiments on their site. Experiments listed here are organized based on their experiment numbers; they are alphabetized in the characters tab on the sidebar to the right.

    • X-007/Gigi: Designed to annoy others by constantly barking. Looks like a Shih Tsu, she was adopted by Mertle Edmonds as the girl's pet "dog".
    • X-010/Felix: Designed for cleaning purposes. Also known as "Oscar" when he's re-programmed to spread dirt.

    • X-254/Mr. Stenchy: Designed to allure enemies with his cute charm in order to get them to take him to their headquarters, then in 42 hours he emits an odor so noxious that it would render a whole region inhospitable. He was sent to Pleakley's home planet as his species actually appreciates the smell.
    • X-258/Sample: Designed to annoy others with sounds that the records and plays back repeatedly. He provides backbeats for a previously rhythmless band.

    • X-602/Sinker: Designed to cut vessels with his large, sharp dorsal fin. He works at a Japanese restaurant making sushi.
    • X-603/Zap: Designed to be a living laser bolt.
    • X-606/Holio: Designed to turn into a black hole. He works in construction sucking up debris.
    • X-608/Slugger: Designed to deflect enemy projectiles with his baseball bat-shaped tail. He works as a Little League Baseball coach.
    • X-613/Yaarp: Designed to emit deafening sonic blasts. He works as an alien invasion alarm at Lilo's halau hula (hula school).
    • X-617/Plasmoid: Designed to fire hot plasma from his tail.
    • X-619/Splodyhead: Designed to fire hot plasma from his lone nostril. He works at David's luau lighting tiki torches.
    • X-621/Chopsuey: An early prototype of 626 who only appears in Disney's Stitch: Experiment 626, which was retconned by the film Lilo & Stitch 2: Stitch Has a Glitch.
    • X-624/Angel: Designed to sing a siren song that reverses the morality of reformed creatures, primarily the experiments made before her. Stitch's girlfriend and the only predecessor he does not call a "cousin"; they call each other their "boojiboo", a word in their Tantalog language that essentially means "sweetheart" or simply "my love".
    • X-625/Reuben: Designed for the same purposes as his immediate successor, but is too much a lazy coward to do so. He can speak English fluently and loves to make delicious sandwiches. He was first activated in Stitch! The Movie, but he was the last experiment to receive his name (in Leroy & Stitch). After that film, he works with Gantu in the Galactic Armada as a galley officer.
    • X-626/Stitch: Designed to destroy large cities and "everything he touches". The franchise's "cute and fluffy" titular lead, he defied his destructive programming after meeting Lilo.
    • X-627: Designed to be a much more powerful version of Stitch without any capability of reforming. He loves to laugh, but doing so hurts him. Since he cannot be reformed, he was dehydrated back into a pod and stored away by Jumba.
    • X-629/Leroy: Stitch's evil twin was made under the demands of Dr. Hämsterviel who was cloned shortly after creation. Until June 2020, he had no official experiment number; he was deemed to be Experiment 629 in a Disney Tsum Tsum-exclusive side story of the web manga Tono & Stitch, known in English as Stitch & the Samurai. Thanks to a fail-safe Jumba programmed in him (the song "Aloha 'Oe"), he and his clones were shut down and sent to galactic prison with Hämsterviel.
