Mr. Jameson (voiced by Bryan Cranston): The father of Keoni and, on several occasions, Nani's employer. He owns several businesses around Kauai, including the Birds of Paradise Hotel. X-626/Stitch – A blue koala-like experiment who was designed to cause chaos and destruction, but defied his destructive programming after being adopted by Lilo. Being the titular lead of the franchise, he is the only experiment to appear in all the franchise's films, television series, video games, and theme park attractions, among other works.

X-199/Nosy – A red, large-nosed, wombat/pig-like experiment who is designed to seek out and reveal people's most embarrassing secrets, though it's usually useless gossip. Lilo and Stitch gave him to Gantu at the end of Nosy's debut episode, but he escapes in "Woops". He, along with Fibber above, 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 they were captured by Gantu at the time. He was voiced in The Series by Bobcat Goldthwait and in the anime by Roger Craig Smith. The development of Lilo's ʻohana (extended family) begins with the adoption of Stitch in Lilo & Stitch. Though Lilo technically owns Stitch by Hawaiian state law, the relationship between the two is more like siblings and best friends. By the end of the series, Lilo's extended ʻohana includes Nani, "Uncle" Jumba and "Aunt" Pleakley, David, Cobra Bubbles, the Grand Councilwoman, Victoria, all 627 (627 and 628 were shown dehydrated in the episode of 627, although it could be argued that they still count) of Stitch's "cousins", Gantu and finally Mertle. X-251/Link – A small, bright yellow, pudgy, vaguely rabbit-like experiment with red eyes 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. He first appeared in Leroy & Stitch before his episode aired as the last episode of Lilo & Stitch: The Series. He was voiced in the anime by Keith Silverstein. X-133/PJ – An orange and tan koala-like experiment with a red nose and a functioning blowhorn for a tail (reminiscent of Harpo Marx's trademark horn) which he squeaks instead of speaking. He normally wears Groucho Marx glasses. 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. PJ is seen without his glasses in Leroy & Stitch during the " Aloha ʻOe" concert and in the group photo taken at the end of the film. He was voiced by Jeff Bennett in The Series and Roger Craig Smith in the anime.

X-120/Snafu – A small, teal, large-headed, octopus-like experiment who 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. He is named after the military acronym SNAFU.

Lilo & Stitch (2002) takes place in Hawaii and follows the story of Lilo, a young and parentless girl who adopts Stitch from the local pound, absolutely oblivious to the fact Stitch is an alien experiment that landed on Earth and is now hiding from its creators and those who see it as a menace. The Grand Councilwoman is the leader of the United Galactic Federation. Others occasionally refer to her as 'Your Majesty' and 'Your Highness', and on the whole, she seems both reasonable and well-intentioned, although, like many members of the United Galactic Federation, she knows almost nothing about Earth or its inhabitants. She is of an unknown species by name, but she seems to be reminiscent of a grey alien, with hoof-shaped feet, big eyes, and a big head. She was voiced by Australian actress Zoe Caldwell. It seems, that the Grand Councilwoman has a status as the supreme ruler of the galactic federation (similar to an empress in an empire). X-001/Shrink – A small, purple, three-legged, levitating experiment who can fire a ray to change the sizes of objects and creatures. He cameos in Leroy & Stitch and later appears in two episodes of Stitch!. He was voiced in the anime episode "Experiment-a-palooza" by Keith Silverstein.

X-122/Dorkifier – A pink and white calf-like experiment who is designed to fire a ray from his horns that changes his victims' appearance into something ridiculous. The new dorky clothes can only be taken off when his horns are turned down. He was introduced in the Stitch! anime, which did not credit his voice actor. Lilo's parents died in a car accident some time before Lilo & Stitch (it is suggested that rain made road conditions treacherous), and they have not appeared in the series apart from three photographs: one of Lilo, Nani, and their parents having a picnic on the beach, a photograph of Lilo's mother winning the Hula contest at her school's May Day celebration, and a photo of Nani with her parents when she graduated to intermediate Hula. About 100 experiments were designed for Lilo & Stitch: The Series, which initially wasn't going to feature the other 625 experiments made before Stitch. [14] [15] On a TV Tome thread held by Lilo & Stitch: The Series executive producer Jess Winfield (under his TV Tome username "jesstifer"), he stated that during the show's development, Walt Disney Television Animation artist and director Steve Lyons suggested that Lilo and Stitch would hunt down various creatures that a villain would make from cloning Stitch. [14] Over time, the idea of the Stitch clones would change to the 625 experiments before Stitch after someone else suggested them instead. [14] Winfield didn't remember who first thought up of the idea of using the other 625 experiments, although he believed it was either himself, fellow executive producer Bobs Gannaway, or then-president of Walt Disney Television Animation Barry Blumberg.

X-110/Squeak – A small red mouse-like experiment who is designed to annoy entire planets by talking ceaselessly. His appearance and ability is a reference to the Looney Tunes character Sniffles.

X-234/Shush – A reddish-pink opossum/mouse-like experiment with large ears and a speaker at the end of its long and fluffy ringed tail who 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. Hypnotism through a siren song that affects the morality of listeners (primarily experiments made before her)

Experiment 627 – A red koala-like experiment who is Jumba's first experiment made using the limited technology he has on Earth. He is more powerful than Stitch, with higher strength, greater durability, and more abilities without any of the same weaknesses as his predecessor. X-010/Felix – A green anteater/elephant-like experiment who is designed to be Jumba's cleaner, but was too obsessed with cleanliness. A re-programming to fix this flaw made him obsessed with dirtiness instead, with Lilo calling him an " Oscar". Lilo and Stitch initially gave up on Felix and gave him to Gantu, but they later rescued him in "Snafu". Both this experiment's names are references to the lead characters of The Odd Couple. He later appeared in the anime, being one of only three experiments other than Stitch and Reuben to appear in the first season (before more appeared in the later seasons), and has also appeared as a playable character in Disney Stitch Jam and a costumed character in Tokyo Disneyland and Disneyland Paris, usually with other experiments. X-228/Melty – A small, red, dragon-like experiment who 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 was voiced by Tress MacNeille. a b "Captain Gantu Voice - Stitch & Ai (TV Show)". Behind the Voice Actors . Retrieved February 27, 2021.
