Tropes for any of these experiments can be found in the "General" folder back on the main Experiments page.

• X-300: Spooky — 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. His pod is green in The Series and red in the Stitch! anime. (Appearances: "Spooky", "The Asteroid", "Checkers", Leroy & Stitch, Stitch!, Lilo & Stitch 2: Hämsterviel Havoc^note American and European cover only)

• X-314: Jones
• X-315: Chum
• X-316: Morpholomew — 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. His pod is yellow. 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. (Appearances: "Morpholomew", Leroy & Stitch, Stitch!)
• X-317: Hyuckster
• X-318: Chortle
• X-319: Spike — See folder below
• X-320: Cloudy — 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. His pod is white. (Appearance: Leroy & Stitch)
• X-321: Lightfoot
• X-322: Heckler — 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. (Appearances: "Heckler", Leroy & Stitch)
• X-323: Hunkahunka — 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.

• X-340: Nodessertro (a.k.a. Whatsisname) — 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. His pod is white. (Supposed appearance: Leroy & Stitch)
• X-341: Wafty
• X-342: Greensleeves
• X-343: Chaching
• X-344: Dupe — 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. (Appearances: "Dupe", "Remmy", "Snafu", Leroy & Stitch, Stitch!, Disney Tsum Tsum^note Was originally a non-playable event character and later cameos in Gantu's ability)
• X-345: Elastico — See folder below
• X-346: Stuckup
• X-347: Slobber — 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.

(Appearance: Comic Zone: Lilo & Stitch)
• X-348: Snappish
• X-349: Lotuseater — This experiment's pod was seen in the experiment profiler special feature on the Lilo & Stitch 2: Stitch Has a Glitch DVD.

• X-351: Whoover
• X-352: Yvonne
• X-353: Blackoutro
• X-354: Jesstifer — This experiment is named after The Series' executive producer and writer Jess Winfield's username on TVTome/TV.com. Its function is unknown and its pod is red.
• X-355: Swapper — A two-headed, four-armed green lizard-like experiment who is designed to switch people's minds. Only he can undo the switch.

(Appearances: "Swapper", Leroy & Stitch, Stitch!)
• X-356: Rippington
• X-357: Downes
• X-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. (Appearances: "Mrs. Hasagawa's Cats", Leroy & Stitch)
• X-359: Phoebe
• X-360: Drowsy — 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. His pod is yellow. (Appearances: "Drowsy", "PJ", "Ploot", "Remmy", Leroy & Stitch)

Notable 3-series experiments

Amnesio (Experiment 303)

Voiced by: Tress MacNeille
Pod color: Yellow
Appearances: Lilo & Stitch: The Series — "Amnesio", "Woops", "Snafu" | Leroy & Stitch | Stitch! — "The Return of Amnesio"
Appearance in other media: Disney Tsum Tsum^note non-playable event character only

A small, blue beetle-like experiment who 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 How Jumba knew the word, which is Hawaiian, and why he chose that particular word are unknown, though it is possible that it's actually the word, "family", but it works if said in any language. 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 also 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, their memory will return. However, only Amnesio knows whose memory belongs to whom.

---

• "Freaky Friday" Flip: His anime portrayal can indirectly cause this. If someone ingests the wrong memory pouch, then they essentially become the person to whom that memory pouch belonged. This was shown at the end of Amnesio's only anime episode when Gantu ingested BooGoo's pouch and vice versa.
• Flight: He has the ability to fly with his wings.
• Insectoid Aliens: He resembles a beetle with bug-like antennae and wings and is an alien experiment.
• Laser-Guided Amnesia: His entire purpose. He uses his laser vision to remove others' memories.
• Weaksauce Weakness: As shown in his anime episode, putting on a pair of sunglasses prevents him from using his abilities, although he doesn't really mind all that much.

Spike (Experiment 319)

Voiced by: Frank Welker, Keith Silverstein (Stitch!)
Pod color: Yellow (in The Series), White (in Stitch!)
Appearances: Lilo & Stitch: The Series — "Spike" | Leroy & Stitch | Stitch! — "Link-age", "Spike 2.0", "Shogun",^note in pod form "Dark-End", Stitch and the Planet of Sand

A large dark blue porcupine-like experiment who 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.

---

• Adaptational Villainy: He's one of the experiments Hämsterviel has control over in the anime, although he reforms at the end of the second season episode "Link-age". However, his third season episode "Spike 2.0" has him inexplicably under Hämsterviel's control again, this time transmutated.
• Beautiful Tears: After Pleakley hugs him he lets out a cute cry that causes the other E.A.R.W.A.X. experiments to tear up.
• Cuddle Bug: After Pleakley hugs him while wearing a suit of armor, Spike wants to give others hugs to comfort them in spite of giving them stupidity.
• Defrosting Ice King: He is very cranky until Pleakley hugs him for the first time. Then he turns into a Cuddle Bug.
• Desperately Craves Affection: Implied to be the reason he's so aggressive and grouchy all the time, as his spikes prevent anyone from making close contact with him. Shown that when Pleakley hugs him he starts to try and escape, only to burst into tears in seconds and embrace him.
• Heel–Face Revolving Door: Thanks to the anime; he started out bad in Lilo & Stitch: The Series but was reformed midway through his episode and stayed that way in Leroy & Stitch. Then in Stitch!, which takes place years after Leroy & Stitch, he's bad again and under Hämsterviel's control in "Link-age", but reforms again at the end of the episode. But thanks to Series Continuity Error caused by the third season's switch in animation studios from Madhouse to Shin-Ei Animation, Hämsterviel's controlling him again in "Spike 2.0" via transmutation. He gets re-captured at the end of that episode, is shown dehydrated into pod form in "Shogun", and finally re-appears in "Dark-End" having been cleansed of his transmutation by Jumba, and he stays reformed as shown by his cameo in Stitch and the Planet of Sand.
• One-Shot Character: In The Series, sadly. He would've made a second appearance in "Ace", but his scenes were cut when the episode was reworked into a Clip Show after the 2004 Boxing Day tsunami. Averted in the anime, however, where he got a few more appearances than before.
• Phlebotinum-Induced Stupidity: His spikes reduce a person's intelligence by 99% for 48 hours. Jumba was also affected, but he didn't feel it because for someone with Super-Intelligence, "1% is still plenty of genius".
• Spike Shooter: He looks like a porcupine and was formerly aggressive with shooting spikes at others, until attending Pleakley's therapy session.

Elastico (Experiment 345)

Voiced by: Jeff Bennett (Lilo & Stitch: The Series), Wally Wingert (Stitch!)
Pod color: Unknown
Appearances: Lilo & Stitch: The Series — "Elastico", "Checkers", "Remmy" | Leroy & Stitch | Stitch! — "Elastico 2.0", "Dark-End", Stitch and the Planet of Sand

A green, furless, earless, clownish, roughly monkey-like experiment with three huge tendrils on his head that resemble a jester's cap who wears a pink neck frill. 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. In the anime, he was transmutated by Hämsterviel so that he could transform creatures and objects respectively into circus-related animals or animal-themed objects.

---

• Aliens Speaking English: Implied by speaking one word as a response to Stitch in his debut, but confirmed by his later appearance in the anime.
• Face–Heel Turn: In his first episode of the anime, in which Hämsterviel had somehow managed to capture him sometime before the events of the show and transmutated him to go after Stitch.
• Hates Being Touched: Downplayed; he hates being grabbed or restrained, but he will gladly hug others.
• Heel–Face Turn: After he was defeated and captured in the anime, Jumba removed his transmutation off-screen between "Elastico 2.0" and the experiment's second anime appearance in "Dark-End", when he joins Stitch in the fight against Dark End.
• Nice Guy: He was good before Stitch even met him and he only joined the circus to entertain others.
• Non-Ironic Clown: He genuinely wants to entertain others with his stretching ability, though the non-ironic part was temporarily reduced in his first anime appearance.
• Rubber Man: He can stretch his body and make it take on any shape.
• Suddenly Voiced: Played with; he spoke just one word ("Cousin?") and made various noises in his debut, but speaks fluently in Stitch!.
• The Transmogrifier: In the anime, where Hämsterviel transmutated him so he now had the ability to transform anyone and anything (including himself) into circus-based animals. The only way that the effect can be undone is if he's defeated. (If he transforms himself, though, then he can revert back to his normal form on his own, implying that he could also choose to undo the effect on his victims.)

Swirly (Experiment 383)

Pod color: Yellow
Appearances: Lilo & Stitch: The Series — "Swirly", "The Asteroid" | Leroy & Stitch | Stitch! — "Stitch Power"^note Japanese-exclusive episode

A small, big-headed, turquoise koala-like experiment with big black eyes and a large furry slug-like tail who 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.

---

• Ascended Extra: Heavily downplayed. Swirly appears on one clip art with Stitch where the former hypnotizes the latter; this clip art was used by Spencer's Gifts for some merchandise released late in The New '10s, including a bifold wallet and a snapback hat, making him one of the only known experiments besides the much more popular Stitch and Angel to have merchandise sold in the United States in the years after Lilo & Stitch: The Series. Even then, he only ever got on such merch to begin with because he appeared with Stitch.
• Early Installment Character-Design Difference: Also crossing over with a minor case of Inconsistent Coloring, Swirly is colored green with black and pink swirling eyes in his debut episode, while he's turquoise with black and white swirling eyes in all his other appearances (and in promotional artwork).
• Hypnotic Eyes: How he performs his hypnosis. Lilo decides to give Swirly his name because of that fact.
• Mind-Control Eyes: He gives anyone who's caught by his hypnotic gaze these while they're paralyzed, but it fades once the hypnotized victim has received a suggestion on which to act.
• The Stoic: Hardly makes any expression in his appearances, although his eyes are lidded in "The Asteroid", giving him a tired appearance in that episode.
