Stitch (voiced by
Chris Sanders), also known as Experiment 626, is one of the two lead characters. After finding out about his 625 other experiment "
cousins", he and Lilo set out to find them, reform them to good, and have them join their ever-expanding
ohana. He also learns more about life on
Earth along the way. •
Lilo Pelekai (voiced by
Daveigh Chase) is the other lead character. She is Stitch's owner and best friend. She assists Stitch in finding his "cousins", naming them, and finding them a "one true place" where they can use their abilities for good. •
Dr. Jumba Jookiba (voiced by
David Ogden Stiers) is the creator of the many genetic experiments, which include Stitch and Reuben. He lives with the Pelekai
ohana after being exiled to Earth in the original film alongside Pleakley. He plays the role of Lilo and Nani's "
uncle" in the
ohana and wears a human disguise in public. He frequently assists Lilo and Stitch in capturing the experiments, usually by providing them with
expositions on his experiments and various tools he creates. •
Pleakley (voiced by
Kevin McDonald) is a former agent for the United Galactic Federation. He lives with the Pelekai
ohana after being exiled to Earth in the original film alongside Jumba. He plays the role of Lilo and Nani's "
aunt" in the
ohana and frequently
cross-dresses in the role. He also assists Lilo and Stitch in capturing the experiments but to a lesser extent. He normally helps Nani out in maintaining the household. Being a self-proclaimed "Earth expert", he always tries to experience what Earth has to offer based on his obscure,
mass media-based research. In the episode "Fibber", it was revealed that his first name is Wendy. •
Gantu (voiced by
Kevin Michael Richardson) is Hämsterviel's henchman who was forcibly retired from his position by the Grand Councilwoman as captain of the Galactic Armada at the end of the original film. He fights against Lilo and Stitch in capturing the experiments but is frequently defeated due to his arrogance, clumsiness, and Stitch's superior abilities. •
Nani Pelekai (voiced by
Tia Carrere) is Lilo's older sister and
legal guardian, and caretaker of the household that they live in. She is always busy and
burned out, and constantly has to deal with Lilo and Stitch's shenanigans. She works in a surfboard and beach equipment rental hut on Lahui Beach in early season one but switches her employment to the rental wing of the Birds of Paradise Hotel midway through the season. •
X-625 (voiced by
Rob Paulsen) is Gantu's sidekick in capturing experiments. He is a genetic experiment who has all the abilities of Stitch but is a fluent speaker of the
English language. However, he is a lazy coward who prefers to make sandwiches rather than fight. He is referred to by his experiment number throughout
The Series; he was not given a name until
Leroy & Stitch, where Lilo baptizes him as "Reuben", although Lilo calls him "Sandwich Boy" once in the episode "627". •
Dr. Jacques von Hämsterviel (voiced by
Jeff Bennett) is Jumba's former lab partner who seeks to capture the genetic experiments he helped to create through financing, hiring Gantu for help. He works from his "prison cell" which he set up as a laboratory. His name is usually mispronounced much to his chagrin, usually as "Hamsterwheel" or "Hamsterveal".

running gag throughout the
Lilo & Stitch franchise. Whenever he appears, he drops his
ice cream (usually a
mint-flavored ice cream, presumably from its color) from its cone before he can finish it. This character has no speaking parts in
