"Battlefield or doomsday experiments with galactic implications." In other words, these are Dr. Jumba Jookiba's most powerful experiments. Experiments that don't have an official number are also listed here for convenience.
List of 6-Series and unnumbered experiments
|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||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!, Disney Sorcerer's Arena|
|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!|
|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||Green||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.|
|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.|
|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!, Disney Tsum Tsumnote|

|628||N/A||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".|
|629||Leroy||N/Anote||See folder below||Leroy & Stitch, Disney Tsum Tsum,note Tono & Stitchnote|
|Skunkuna||A black and white skunk-like experiment with a beak, three antennae on his head and two antennae on his tail. According to the English dub of the Stitch! anime, he was made by Dr. Hämsterviel instead of Jumba, and thus is not part of Jumba's numbering system. He is able to shoot explosive pellets that release an unbearable stench upon impact. He falls in love with Mr. Stenchy, who has a similar stench-releasing ability. When the stenches of Skunkuna and Mr. Stenchy combine, they form a perfect aroma. Many fans assumed that the experiment is actually Experiment 126/Stank and the English dub completely changed his identity, but Jess Winfield has stated that the Japanese original did name the experiment "Skunkuna" as it was written on the translated scripts the English dubbing team received for the episode's "reversioning".||Stitch!|
|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 (hence why he's here instead of on the 0-Series page), 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!|
Notable 6-Series experiments
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.
- Adaptational Villainy: He's one of the experiments that Hämsterviel has control over in the anime.
- The Bully: He loves to pick fights. This trope is what he was designed to do, really.
- Everything's Better with Spinning: Like his inspiration, he can spin like a tornado.
- Expy: See the above description.
- Multi-Armed and Dangerous: He has four muscular arms, perfect for beating up others. However, unlike his cousins, they are not retractable as far as we know.
- Shout-Out: He is likely named after the now-defunct indoor soccer team, the Philadelphia KiXX.
- Purple Is Powerful: He is a strong purple experiment who is powerful enough to challenge Stitch in a fight.
- Wrestler in All of Us: Some of his fighting styles employs professional wrestling moves.
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.
- Bioweapon Beast: Like most of the 6-series, but particularly noticeable in his case due to being based off a specific weapon (a Plasma Cannon).
- The Cameo: In Big Hero 6, his image appears on a pillow in Fred's bedroom, making him the first of Stitch's cousins to appear in the Disney Animated Canon in some form.
- Evil Smells Bad: In the anime, his ability was modified by Hämsterviel to fire purple balls of a terrible odor. Said modified ability would be reversed so he would expel a more pleasant smell.
- Plasma Cannon: He is a living one, although the plasma he fires look like fireballs, not the green blobs we see throughout the franchise.
- Playing with Fire: His main ability, although it's actually hot plasma that he fires.
- The Rival: To Slushy (523), Splody'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:
- Jumba mistakenly referred to Splodyhead as Experiment 515 in "Slushy". 515 is the number of Deforestator.
- Splody's pod is blue in his debut episode, but red in the anime.
- Wall Crawl: He was shown to have this ability◊ much like Stitch.
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.note 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 still has his original design, function, and abilities.
- Aliens Speaking English: He speaks fluent English with a vaguely Russian accent much like Jumba.
- Evil Laugh: He randomly bursts into maniacal laughter.
- Green-Eyed Monster: He was very jealous of 626 and tried to prove himself to be the superior experiment over the younger experiment. It didn't work.
- Flawed Prototype: Has Stitch's powers and abilities, but he's not as capable as him.
- Multi-Armed and Dangerous: Has four arms, but they don't seem to be retractable.
- No Name Given: In his only appearance as it was a prequel to the events of the original film. He was named by the time of Leroy & Stitch, however.
- One-Shot Character: Only appeared in a Spin-Off prequel video game that got decanonized after a sequel film came out.
- One-Winged Angel: After his mutation.
The Mid Six-TwosThis 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.
Voiced in Japanese by: Madoka Takeda (Stitch!, Disney Stitch Jam games)
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 later falling in love with Stitch, so Gantu captured her and took her away in retaliation. She was rescued — partially by Lilo and Stitch and partially by herself — 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.
- Beauty, Brains, and Brawn: The Beauty of the Mid Six-Two experiments, being the most attractive, the best singer,note and the only female of the three. That said, she has shown some of the other two parts of this trope in The Series and Leroy & Stitch.
- 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 arguably the most popular experiment besides Stitch himself that the franchise ever introduced, to the point where the anime has featured her much more often. She arguablly even has more merchandise than Lilo.
- BrotherSister 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. Shes also played this role in some of the licensed games, such as Stitch Jam.
- 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 white V-shaped chest marking that (fittingly) resembles angel wings.
- 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 asymmetrical 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.
- HeelFace Revolving Door: While not exhibited by her herself, this is the basis of her primary function, able to invoke a FaceHeel Turn in any experiment made before her (and Jumba) with a song, and can invoke a HeelFace Turn in the same by singing it backwards.
- HeelFace 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. She realizes that she does have feelings for the dedicated, sweet-hearted Stitch, and decides to defy Gantu and Hämsterviel to save him.
- 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.
- Mascot: The de facto one of the experiments other than Stitch, considering she's the only one of the first 625 that Disney is willing to promote nowadays.
- 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 in that the main reason she was introduced was to give Stitch a love interest.
- Series Continuity Error:
- In The Series, the marking on her back changed from looking like an upside-down heart in her first episode to looking similar to Stitch's in "Snafu" (also gaining a marking on the back of her head, but it only appears in that episode) to outright disappearing in Leroy & Stitch and in some moments in "Snafu" as well. The anime was also inconsistent, with some episodes using the two markings from "Snafu" and others having only the upside-down heart marking. On the other hand, merchandise of Angel seem to firmly establish that the upside-down heart pattern is the one true marking on her back.
- In addition, her fur was a deeper shade of pink in her debut episode compared to all her later appearances.
- 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. (Although that's not the real reason why she was taken out for so long.) 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 (even though she always came back to him).

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: Lilo & Stitch but was changed to golden-colored for the films and TV series to better differentiate him from Stitch.
- 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. He is also implied to know several other Earth-based languages.
- Appropriated Appellation: After a few attempts he wasn't proud of, he takes to Lilo's last name suggestion, Reuben.
- Beauty, Brains, and Brawn: The Brains of the Mid Six-Two experiments. Although he has the exact same strength as Stitch, his laziness negates the Brawn aspect, and he isn't as "cute" or attractive as the more popular Stitch or Angel. But he's easily the Brains considering he's more fluent in English than Stitch and Angel (both of whom do not speak English as fluently), makes tons of snarky quips, knows a lot about the experiments before his time, and is able to use Awesomeness by Analysis the most effectively.note
- Because You Were Nice to Me: Lilo wins him over by naming him and actually befriending him.
- Big Eater: Mostly of sandwiches.
- Bioweapon Beast: Like Stitch, he's a genetic experiment meant to be an ultimate superweapon. Unlike Stitch, he's too lazy to use his powers properly.
- 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 in a series of Disney Adventures Comic Zone Prequels to the first movie.
- Deadpan Snarker: One of his main functions.Gantu (injured from his fight with X-601/Kixx): I will not be made a fool of!
X-625/Reuben (immediately without even facing Gantu): Too late.
- Deuteragonist: In Leroy & Stitch, where he gets his HeelFace 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.
- Early Installment Weirdness: The prequel comics gave him teal fur, smaller eyes, a collar, less prominent buckteeth (they don't even stick out when his mouth is closed) and an even chunkier body. The later Lilo & Stitch: The Series-based comics that featured him changed him to better resemble his canonical animated counterpart, but kept the teal fur.
- 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. There is some justification here if you've read the prequel comics; Jumba considered 625 a failure and frequently disparaged him... except for his sandwiches.
- 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.
- HeelFace 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! No.
- Lovable Coward: He's absolutely useless as a sidekick, but he's still an adorable looking experiment.
- Meaningful Name: He's named after a type of sandwich, the very food he loves. Also, since Reuben is behaviorally the most human-like experiment, his name is a more natural-sounding human given name, which he prefers over the siller names Lilo gives the other experiments (625 even rejected a few Punny Name suggestions from her before settling on "Reuben").
- Mundane Utility: He has extendable claws, but the first time we see them, he's using them like butter knives to spread some grape jelly on a sandwich.
- 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.
- Series Continuity Error: Reuben's pod is blue in Stitch! The Movie, although it appeared as purple in some frames of that film. In the anime episode "Stitch's Birthday: Part 1", when Reuben was dehyrated, his pod appears as white.
- 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.

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.
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.
- Gone Horribly Right: Meant to have extra everything Stitch had. This includes an extra sense of humor, causing his laughter to inconvenience him.
- The Juggernaut: Good grief, when he gave Stitch a No-Holds-Barred Beatdown...
- HeelFace 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 also appears in "Stitch Meets High School Musical" 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.
- Superior Successor: Designed to be a better (albeit worse) Stitch, having improved versions of his powers, none of his weaknesses and some of the other experiments' abilities.
- 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.)
- Ascended Fanon: Fans and fansites (including wikis) were calling Leroy "Experiment 629" for years before Tono & Stitch officially christened him with the number.
- 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, Disney Tsum Tsum, and some official promotional descriptions for his film describes him as this towards Stitch, since they have identical powers and Leroy was made (from the same 626 template, no less) 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: This was Inverted until June 2020; 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 gave 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. In 2018/2019, Disney Tsum Tsum reaffirmed the lack of a number in both the Japanese and Global versions for a Lilo & Stitch: The Series-based event. This flip-flopping of Leroy's experiment number in official Disney media finally ended in June 2020 when a volume of the Feudal Japan-set web manga Tono & Stitch that was released exclusively through the Japanese version of the mobile game gave Leroy the title of Experiment 629.
- One-Shot Character: In the main canon, he appeared only in Leroy & Stitch. His only other official appearance in any Disney media since (outside of merchandise) was in Disney Tsum Tsum for a September 2018 event in the Japanese version and a January 2019 event in the Global version. He eventually made his second ever in-franchise appearance on June 4, 2020, almost fourteen years since his debut, in the web manga Tono & 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.
