Lilo Pelekai (voiced by Daveigh Chase) - One of the two lead characters, 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.
Stitch (voiced by Chris Sanders) - One of the two lead characters, also known as Experiment 626. 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 ʻohana. He also learns more about life on Earth along the way.
Jumba Jookiba (voiced by David Ogden Stiers) - The creator of the many genetic experiments, which includes Stitch and Reuben, he lives with the Pelekai ʻohana after being exiled to Earth in the original film alongside Pleakley. He plays the role of Lilo and Nani's "uncle" in the ʻohana and wears a human disguise in public. He frequently assists Lilo and Stitch in capturing the experiments, usually by providing them with various tools he creates.
Wendy Pleakley (voiced by Kevin McDonald) - A former agent for the United Galactic Federation, he lives with the Pelekai ʻohana after being exiled to Earth in the original film alongside Jumba. He plays the role of Lilo and Nani's "aunt" in the ʻohana 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. His first name is not revealed until the episode "Fibber".
Nani Pelekai (voiced by Tia Carrere) - Lilo's older sister and legal guardian, and caretaker of the household that they live in. She is usually busy and stressed out, and frequently has to deal with Lilo and Stitch's antics.
Jacques von Hämsterviel (voiced by Jeff Bennett) - He 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".
Gantu (voiced by Kevin Michael Richardson) - Forcibly retired from his position as captain of the Galactic Armada at the end of the original film, he serves as Hämsterviel's henchman. He fights against Lilo and Stitch in capturing the experiments, but is usually defeated due to his arrogance, bad luck, and the abilities of Stitch.
625 (voiced by Rob Paulsen) - Gantu's sidekick in capturing experiments, he is a genetic experiment who has all the abilities of Stitch (plus a greater fluency in English). However, he is a lazy coward who prefers to make sandwiches rather than fight. Although he is now known as "Reuben", he was not given this name until Leroy & Stitch, and was referred to by his experiment number throughout the series, although Lilo called him "Sandwich Boy" once in the episode "627".
Mertle Edmonds (voiced by Liliana Mumy) - Lilo's classmate and rival. She appeared in many episodes of the series, usually causing conflicts for the title duo in the episodes she appeared in.
Gigi (voiced by Tress MacNeille) - Mertle's pet, also known as Experiment 007. Gigi is a Shih-Tzu like experiment and the one place where she truly belongs is with Mertle as her pet.
Angel (voiced by Tara Strong) - Stitch's main love interest, also known as Experiment 624. Angel is a pink pretty experiment who designed to turn evil the good experiments with a siren song. She was caught by Gantu and rescued in "Snafu". She appeared in only that episode and her eponymous debut, along with a cameo appearance in "Remmy". Her place who truly belongs is with Stitch as his true love.
Sparky (voiced by Frank Welker) - The first of Stitch's cousins that Stitch met, also known as Experiment 221. Sparky is a yellow experiment designed to create electric energy. His place who truly belongs is in the old lighthouse to use his electric skills to make it light. Appeared in the most episodes of the series.
David Kawena (voiced by Dee Bradley Baker) - Nani's boyfriend. David is a great surfer. Like Nani, he also has trouble finding employment. He is also one of only five humans (the other four being Nani, Victoria, Cobra Bubbles and later Mertle) who are aware of the aliens.
Yuki, Elena and Teresa - Mertle's possé consists of Yuki (voiced by Lili Ishida), Elena (voiced by Jillian Henry) and Teresa (voiced by Kali Whitehurst). They usually travel in a group and seldom say anything other than a sarcastic "Yeah!" in unison when agreeing with Mertle on something.
Grand Councilwoman (voiced by Zoe Caldwell) - the leader of the Galaxy's ruling Federation, she is the one who banished Stitch in the first movie. She later agrees to let Lilo and Stitch become official experiment hunters in order to retrieve all of the remaining experiments. She appeared in only one episode of the series ("Finder").
Keoni Jameson (voiced by Shaun Fleming) - Keoni is a young, laid-back boy on whom Lilo has a crush. Lilo constantly tries to vie for his affections. He had a crush on Pleakley, whom he knows as Lilo's "aunt", in the episode "Hunkahunka", but in "Nosy" he stated that he only had the crush for that one week. His father owns several businesses on Kauai. He has a friend who just happens to be a girl (not a girlfriend, though). This friend is first shown in "Hunkahunka" and later seen in "Morpholomew".
Mr. Jameson - Mr. Jameson is the father of Keoni and, on several occasions, Nani's employer. He owns several businesses around Kauai, including the Birds of Paradise Hotel.
Moses Puloki (voiced by Kunewa Mook) - The hula teacher of Lilo's school, where he teaches Lilo, Victoria, Mertle, Yuki, Elena and Teresa how to hula. He is very patient with his students and tolerates their antics. Lilo and her ex-friends often call Moses "Kumu" (Hawaiian for teacher).
Officer Kahiko - Officer Kahiko is a police officer who knows Lilo well and occasionally tries to keep her out of trouble when she isn't accompanied by Nani. He appears in the episodes "Holio", "Bonnie & Clyde", "Snooty", and "Shush".
Victoria (voiced by Alyson Stoner) - Lilo's new (human) best friend, whom she meets in the episode "Swapper". Throughout the episode, Lilo tries to prove to her she wasn't weird. But in the end, Victoria reveals she likes weird stuff so she and Lilo become best friends. Victoria is also in Lilo's Hula Class and owns Snooty (Experiment 277) as a pet. She appears in the episodes "Swapper", "Snooty", "Slick", "Remmy", and "Wishy-Washy".
Mrs. Hasagawa (voiced by Amy Hill) - The little old lady who owns the fruit stand. Several experiments live with her.
Charles and Mary - A honeymooning couple who came to Kauai to relax and have fun, but often face trouble with Stitch's cousins.
Both the original air dates and production numbers do not reflect the actual continuity of the series. Many continuity errors, including many events involving the location and availability of certain experiments, take place later in the series:
Lilo & Stitch: The Series was originally going to be named Stitch! The Series. This decision was later changed, resulting in the mismatched title of its pilot, Stitch! The Movie. The title Stitch! (with the exclamation point) would later be used as the title of an anime series.
The series is still being aired on the Latin American version of Disney Channel from Monday to Friday on an animated block.
One of the characters who debuted in this show (Splodyhead) was given a cameo in Big Hero 6 as one of the pillows on Fred's bed. This makes Lilo & Stitch: The Series the first Disney sequel TV series to be referenced in a Disney Animated Canon film.
