# List of Lilo & Stitch characters

Disney's Lilo & Stitch is an American science fiction media franchise that began in 2002 with the animated film of the same name written and directed by Chris Sanders and Dean DeBlois. The franchise, which consists of four animated films, three animated television series, an upcoming live-action adaptation, and several other spin-offs, is noted for its unusual and eclectic cast of fictional characters, both human and alien.

## Characters introduced in Lilo & Stitch (2002)
### Stitch (X-626)

Stitch (Experiment 626) is one of the two title characters of the Lilo & Stitch franchise. Originally an illegal genetic experiment created by mad alien scientist Dr. Jumba Jookiba to cause chaos across the galaxy, he is marked by his short temper and mischievous behavior (traits that endear him to his friend Lilo, who adopted him as her "dog"). He is voiced by his creator and the film's co-writer and co-director, Chris Sanders, in all official media, except the Stitch! anime and Stitch & Ai, where he is voiced by Ben Diskin.

### Lilo Pelekai

Lilo Pelekai (/ˈliːloʊ/ LEE-loh) (literally, "lost" in Hawaiian) is one of the two title characters of the franchise. She is a young Native Hawaiian girl who lives on the island of Kauaʻi with her older sister Nani and her extended family of alien visitors marooned on Earth. She is voiced by Daveigh Chase in all the films and Lilo & Stitch: The Series, except Lilo & Stitch 2: Stitch Has a Glitch where she was voiced by Dakota Fanning due to scheduling conflicts on Chase's part.
Lilo is a young girl with long, straight black hair and brown eyes. She is most often seen wearing a muʻumuʻu and sandals, but also wears other warm-weather clothing as well as traditional hula costumes. In Lilo & Stitch 2: Stitch Has a Glitch; her reflection in a mirror is compared to a picture of her young mother, suggesting that they look similar. In the episode "Skip" where an experiment (Experiment 089) is used to skip time ten then another ten years, it is mentioned that older Lilo looks a lot like her sister Nani.
Her spirited and highly eccentric personality, especially in light of her parents' death, has alienated her from her fellow children, yet Lilo makes the perfect best friend for Stitch, an alien experiment whom she adopts as her dog. Lilo attends hula school and her hobbies include the photography of tourists (especially obese people), talking about creatures from horror/sci-fi movies, and rehabilitating Jumba's experiments. In "Swapper", she meets Victoria, who turns out to have similar personalities to her and she becomes Lilo's only human friend.
Lilo is also known for being a passionate fan of Elvis Presley; this trait of hers is based on Lilo & Stitch director/writer Chris Sanders being a fan of Presley himself.
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.
Lilo's mother is depicted as kind and loving (and perhaps eccentric like her younger daughter), as well as an excellent hula dancer. She would placate her children by holding a family night, singing lullabies, and making up funny constellations. Lilo's father played the ukulele and was the one who coined the phrase ʻOhana means family, and family means nobody gets left behind or forgotten. Lilo loves and misses her parents very much; she keeps a picture of them under her pillow and initially would not allow Stitch to touch it.
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, Jumba and Pleakley, David, Cobra Bubbles, the Grand Councilwoman, Victoria, Jumba's experiments, and Mertle.
Lilo does not return as a main character in the Asian series Stitch! and Stitch & Ai. However, she appears as an adult in the third season of Stitch!.

#### Scrump

Scrump is Lilo's personal rag doll that she made herself. "She" (as Lilo treats the doll) is a green doll with a large head (which Lilo passes off by pretending that an insect laid eggs in it), mismatching button eyes and navel, an unevenly stitched mouth, and straw "hair" tied together with a pink bow. The doll is seen throughout the franchise, with Lilo often seen holding it for comfort. Stitch interacts with it on occasion, usually passively, although various merchandise and marketing material portray him as loving the doll and interacting with it frequently. Being an inanimate object, "she" does not speak, although Nancy Cartwright voiced the doll in an episode of Lilo & Stitch: The Series when Experiment 375, also known as Phantasmo, possessed the doll.
In the Stitch! anime series, it is revealed that the now-adult Lilo gave Scrump to her daughter Ani as a hand-me-down.

### Nani Pelekai

Nani Pelekai is Lilo Pelekai's older sister and legal guardian. She carries the burden of supporting herself and her younger sister both financially and parentally. Naturally, she is usually very busy and under a great deal of stress. Her age is not made clear, but the fact that she was made her sister's guardian suggests that she is at least eighteen years old by the time of the first film. She loves Lilo devotedly but does not always understand her. Nani often serves as a gentle voice of reason and advice in the films and show—and occasionally, not so gentle. It was Nani, in the original film, who allowed Lilo to adopt Stitch from the pound, where he had been mistaken for a dog. She is voiced by Tia Carrere in the films and Lilo & Stitch: The Series.
As a result of her stress, Nani is easily aggravated by Lilo and Stitch's antics, which often interfere with her ability to find and hold a stable job. In the original film, she loses her job as a waitress at a tourist-attracting lūʻau due to Stitch attacking a disguised Pleakley (who, along with Jumba, tried to capture Stitch there with an extraterrestrial chicken drumstick). She seemingly gets a new job at a store near her house after Jumba and Stitch's fight that ends with her house's destruction, although she is never seen working there afterward. In early season one of Lilo & Stitch: The Series and in Lilo & Stitch 2: Stitch Has a Glitch, she works at a surfboard rental hut on Lahui Beach. However, partway through the season, she gets a new job at the Birds of Paradise Hotel.

### Jumba Jookiba

Dr. Jumba Jookiba (/ˌdʒʌmbə dʒuːˈkiːbə/ JUM-bə joo-KEE-bə listen, misspelled as Jumba Jukiba in some media) is the creator of Stitch and his "cousins." He is an overweight, purple-and-pink-skinned alien from the planet Kweltikwan/Quelte Quan speaking in a vaguely Russian accent, with dark pink skin, a huge and mostly bald ovalish head with four yellow eyes. He has been called an "idiot scientist", but he prefers to be known as an evil genius and is in fact surprisingly sociable and friendly outside of his work. He was voiced by David Ogden Stiers in the films, Lilo & Stitch: The Series, Disney's Stitch: Experiment 626, and Kingdom Hearts Birth by Sleep, The Series Jess Winfield in the Stitch! anime and Stitch & Ai, and Piotr Michael in Disney Speedstorm.
Jumba's greatest asset is his abnormally high IQ, hindered only by a few small and occasional lapses in memory. His penchant for creating numerous destructive, complex experiments and machinery is nearly unrivaled, and his creation 626 is proof of his genius, being nearly unbeatable, as well as one of the most formidable fighters in the galaxy. He has also completely memorized the number and technical info on every one of Stitch's "cousins" he created.
Jumba graduated from Evil Genius University with Jacques von Hämsterviel, his lab partner. Shortly afterward, it is said the two opened up a joke shop together. When Jumba became the lead scientist of Galaxy Defense Industries, the two began work on Jumba's experiments.
In the first film, Jumba is incarcerated, but later released and sent to Earth with Pleakley to recapture one of his creations, Experiment 626. He was later quietly left on Earth (likely to avoid becoming a nuisance elsewhere in the galaxy) and has become a part of Lilo's extended family.
Jumba also appears in the video game Kingdom Hearts Birth by Sleep.

### Pleakley

Agent Wendy Pleakley, usually referred to mononymously by his surname Pleakley, works for the United Galactic Federation, and acts as its expert on Earth, when in reality he does not know much. He reluctantly becomes Jumba's partner when forced to assist the scientist in capturing Stitch, then later becomes his best friend and roommate when the two are stranded on Earth. Pleakley is voiced by The Kids in the Hall veteran Kevin McDonald in all official Western media. In Stitch!, he is voiced in English by Ted Biaselli, and in Stitch & Ai, he is voiced by Lucien Dodge.
Pleakley is a thin, greenish-yellow alien with three stout legs, a wide mouth with two purple tongues, three elongated fingers on each hand, a round bald head topped with a single small antenna that acts as ear and nose, and one large eye in the middle of his face. His body shape and style of movement resembles the enchanted brooms from The Sorcerer's Apprentice sequence of Disney's Fantasia. Pleakley is shown to be effeminate and dresses in both men's and women's clothing and often wears a wig. He usually wears his Galactic Alliance uniform on official business and a muʻumuʻu while on Earth.
In "Poxy", much of the workings of Pleakley's internal system are revealed when Lilo and Stitch shrink themselves and enter it to retrieve an infectious experiment. He has no skeletal system and has an extremely small brain. In other episodes, his antenna is shown to be a sensory organ similar to a human nose and ear.

### Gantu

Gantu (/ɡæn.tuː/, rhymes with "can too"), known as Captain Gantu in Lilo & Stitch, the end of Leroy & Stitch, and Stitch & Ai, is an extremely large and muscular alien from the ice-covered eighth planet of the Kreplok System with a gruff, militant personality. He resembles a humanoid whale with gray skin, blue eyes, and pillar-like legs, and stands twenty feet tall. He is voiced by Kevin Michael Richardson in Western media, Keith Silverstein in Stitch!, and Richard Epcar in Stitch & Ai.
Gantu lacks any notable abilities, but his immense stature means he has strength well above any human. Aside from his lifting capacity and enormous girth, Gantu is a respected captain of the Galactic Federation and is a skilled pilot and marksman.
In Stitch! The Movie, he is hired by Dr. Hämsterviel to retrieve Jumba's first 625 experiments. Throughout the following Lilo & Stitch: The Series, he works with Reuben in an attempt to capture the experiments for Hämsterviel.
Gantu also appears in the video game Kingdom Hearts Birth by Sleep.

### Mertle Edmonds

Mildred Pearl "Mertle" Edmonds is Lilo's main rival. She is voiced by Miranda Paige Walls in the original film and Lilo & Stitch: Trouble in Paradise, then by Liliana Mumy in the following sequels and television series.
Mertle is established as Lilo's ex-friend at the beginning of Lilo & Stitch, where she is introduced as a popular girl and the leader of a clique composed of herself and three other girls—Yuki, Elena, and Teresa—in the hālau hula. Mertle calls Lilo "Weirdlo" and refuses to include her in the girls' activities. Mertle and the other girls express fear and disgust of Lilo and her things, such as her doll Scrump and Stitch. Mertle takes great pleasure in putting down, insulting, bullying, and making fun of Lilo, in which Lilo sometimes responds (quite violently) by hitting her, pulling her hair, and biting her.
She became a recurring character in Lilo & Stitch: The Series. Throughout the series, it is established that she is from a relatively wealthy family and is a spoiled brat who lives with her mother. In the episode "Yapper", it is revealed that she adopted Experiment 007 as a pet, naming her "Gigi", but does not realize she is an experiment until Leroy & Stitch.

### Cobra Bubbles

Cobra Bubbles is working as a social worker at the time of the original film. He is called to Nani's house to determine the fate of her guardianship over her sister Lilo, only to find Lilo home by herself, the front door nailed shut, and Nani trying to get in via the dog door. After a brief assessment, during which Lilo misinterprets Nani's hand signals, Cobra concludes that Nani is not doing a good enough job. When Nani is fired because of Stitch's violent behavior, he informs her that he can not ignore her being unemployed and gives her three days to get a new job. Cobra's subsequent encounter with Stitch also proves to be less than favorable. He is voiced in the films by Ving Rhames, in Lilo & Stitch: The Series by Kevin Michael Richardson, and in Stitch & Ai by an uncredited Richard Epcar.
Cobra is a former CIA agent and was involved in an incident at Roswell in 1973, presumably through which he knows the Grand Councilwoman. He mentions that he saved the earth from an alien race by convincing them that the mosquito was endangered and that Earth should be turned into a wildlife preserve. When the Grand Councilwoman declares that Nani and Lilo are to be caretakers of Stitch during his exile on Earth, she also implies that Cobra Bubbles is not to divide but instead protect the family.

### Grand Councilwoman

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.
In Lilo & Stitch, the Grand Councilwoman was first seen in a council chamber with the other Galactic Leaders during the trial against Jumba. After asking Jumba's genetic creation, Experiment 626, if he could show some good in him, the Grand Councilwoman sentenced the Experiment to exile on a desert asteroid and Jumba to prison. However, 626 escapes in a police cruiser and she asks if it would be possible to just go to Earth and retrieve him. Pleakley tells her that the planet is a protected mosquito preserve and she later allows Pleakley and Jumba to retrieve 626. During the course of the film, The Councilwoman makes frequent calls to Pleakley, questioning what they are doing and why Experiment 626 has not been captured yet. In her last call to Pleakley, she loses patience and fires him and Jumba, sending Captain Gantu to finish the mission. At the end of the film, she finds that 626 (now named Stitch) found his own family and has changed for the better. She is reluctantly about to take Stitch to serve out his sentence when she learns that Lilo and Nani paid money for Stitch and therefore legally own him, giving the Councilwoman a legal loophole she could use. She happily allows him to stay with the Pelekais in exile on Earth and announces that the family is under the protection of the Galactic Alliance.
The Grand Councilwoman also appears in the video game Kingdom Hearts Birth by Sleep.

### David Kawena

David Kawena is Nani's boyfriend. He is voiced by Jason Scott Lee in the original film and Lilo & Stitch 2: Stitch Has a Glitch and Dee Bradley Baker in Lilo & Stitch: The Series and its films. He is a great surfer who works as a fire performer at the luau where Nani also previously worked in the first film. Very easygoing, he is a close and supportive friend to both Pelekai sisters, having helped them out several times.

### Mrs. Hasagawa

Lynne Hasagawa, usually referred to as Mrs. Hasagawa, is a little old lady with grey hair and wears glasses, and is the owner of the town's fruit stand. In the episode "Mrs. Hasagawa's Cats", she obtains and activates several experiments who she believes to be cats.

### Other characters

* Moses Puloki: Lilo's hula teacher. He is very patient with his young students and is very tolerant of their antics. However, he is often exasperated by the way Mertle and her friends disrespect Lilo. Lilo and her classmates often call Moses "Kumu", Hawaiian for teacher. Lilo oddly calls him "Mr. Petuli" in the Lilo & Stitch: The Series episode "Cannonball", though she later refers to him by his given name Moses in the same episode. He is voiced by Kunewa Mook [d], who is a kumu hula in real life.
* Elena, Teresa, and Yuki: They are three girls that always accompany Mertle and mock Lilo with her. They usually travel in a group and usually say a drawn-out, sarcastic "Yeah!" in unison when agreeing with Mertle on something. Elena is voiced by Jillian Henry and Yuki is voiced by Lili Ishida, while Teresa is voiced by Kali Whitehurst in Stitch! The Movie, The Series, and Leroy & Stitch, and Holliston Coleman in Lilo & Stitch 2.
* Rescue Lady: The operator of Aloha Animal Rescue, Kokaua Town's animal shelter where Lilo adopts Stitch. She has red hair and wears glasses and green overalls. Her real name, according to Lilo's pink slip showing her ownership of Stitch, is Susan Hegarty, which is the name of the vocal coach who voiced her in the original film. She also makes brief appearances in three episodes of Lilo & Stitch: The Series, voiced by Grey DeLisle.
* Ice Cream Man: An unnamed, obese man with sunglasses, swimming trunks (shorts and an aloha shirt in most episodes of The Series), sandals, and a sunburn around his body except for an area on his torso where he wore an A-shirt. He is a running gag throughout the Lilo & Stitch franchise. Whenever he appears, he drops his ice cream from its cone before he can finish it. This character has never spoken in the series except saying "Whoa!" when he tripped over a pod. He also cries after being turned into a baby by Experiment 151 (Babyfier). His real eyes can be seen in "Swirly". He is normally silent but was voiced, briefly, by Frank Welker. In the live-action film, he is a Native Hawaiian instead of a white tourist, and he tries to enjoy Hawaiian shave ice instead of ice cream.
* Luki: A shave ice business owner and vendor who appeared briefly in the original film and a few times in Lilo & Stitch: The Series. In the series, he is voiced by Derek Stephen Prince.
* Pudge: An orange tropical saltwater fish who Lilo believes to have control over the weather. She feeds him a peanut butter sandwich every Thursday to "appease" him. He also appears in the non-canon Chibi Tiny Tales episode "All Hail Pudge!", in which he is depicted as sapient and with actual weather manipulation powers.

## Characters introduced in Stitch: Experiment 626
### Chopsuey (X-621)

Chopsuey (Experiment 621) is one of Stitch's cousins. A green, skinny Stitch look-alike with a spiky yellow mohawk and two prominent fangs jutting from his lower jaw, he has all of Stitch's powers and is jealous of all the attention Stitch gets. He was voiced by Frank Welker.

### Dr. Habbitrale

Dr. Habbitrale is one of many rivals of Dr. Jumba Jookiba. He shares a similar appearance to Hämsterviel, appearing to be of the same rodent-like alien species as him. He was voiced by James Arnold Taylor.

## Characters introduced in Stitch! The Movie
### Dr. Hämsterviel

Dr. Jacques von Hämsterviel (/ˈhɑːmstərviːl/ HAHM-stər-veel) is voiced by Jeff Bennett in Lilo & Stitch: The Series and its films Stitch! The Movie and Leroy & Stitch, while Kirk Thornton voiced him in the Stitch! anime. Hämsterviel is a diminutive rat-like alien scientist who desires to conquer the galaxy. The former lab partner of Jumba, he now seeks to capture the experiments he helped create.
In the Stitch! anime series, Hämsterviel is seen out of prison residing in a laboratory hideout on an asteroid, with Gantu and Reuben working for him again. He now goes out in the open more often to fight against Stitch and his new friend Yuna. He also has a number of experiments in his possession and often sends them out to fight for him; he states in an episode of the English dub that he kidnapped them from Kauaʻi and reverted them back to evil using a recording of Angel's siren song. Additionally, during the anime, primarily its third season ~Best Friends Forever~, he "transmutates" a number of experiments to enhance or change their abilities.
Hämsterviel makes costumed character appearances at Tokyo Disneyland and occasionally at Disneyland Paris. He also appeared in a 2014 Disney Villains-themed event at Walt Disney World called "Villains Unleashed" alongside Gantu.

### Reuben (X-625)

Reuben (Experiment 625) is one of the experiments created by Jumba, and one of Stitch's cousins. Reuben has every ability Stitch has (along with a much better fluency in English, speaking with a Brooklyn accent) but he prefers to make sandwiches than use his powers. He is voiced by Rob Paulsen in the films and Lilo & Stitch: The Series, and by Dave Wittenberg in the Stitch! anime's English dub. Although the character's canonical debut was in Stitch! The Movie, he first appeared in prequel comics published in Disney Adventures before the release of the original film.
Reuben makes occasional costumed character appearances at Disney Parks, usually in events along with several other experiments. He made an appearance in Lilo & Stitch's Big Panic on a float with the villains of his franchise. He made an extremely brief, non-speaking cameo appearance in Stitch's Great Escape! at the Magic Kingdom.

### Sparky (X-221)

Sparky (Experiment 221) is one of the experiments created by Jumba, and one of Stitch's cousins. He can control electricity and move around with it as a method of propulsion, sometimes causing short circuits. He is voiced by Frank Welker, while he is voiced by Steven Blum in the anime's dubbed version. His "one true place" is a disused lighthouse on Kauai, which he can power up for full operation.
Sparky also appears as an enemy in the video game Kingdom Hearts Birth by Sleep, which takes place before the events of the first film. He has also made costumed character appearances in Disney Parks, usually in events with other experiments.

### Jumba's genetic experiments (Stitch's cousins)

The genetic experiments (or simply experiments) are genetically engineered alien creatures created by Jumba Jookiba who are featured throughout the franchise, of which Stitch (Experiment 626) is among them. The experiments, made by Jumba with funding provided by his former partner-in-crime Jacques von Hämsterviel, were primarily designed for causing evil deeds in a variety of forms, ranging from mere annoyances to planetary destruction. Although at least one of them have technically appeared in virtually every Lilo & Stitch-related media—mainly through Stitch—the collective experiments were only a main focus in Lilo & Stitch: The Series (and its pilot and finale films) and the Stitch! anime series. The experiments, in general, were first introduced in the Lilo & Stitch prequel comics shown in Disney Adventures magazine and in the PlayStation 2 prequel video game Disney's Stitch: Experiment 626, which were released before the original film's premiere, but they did not make their official debut in the animated continuity until Stitch! The Movie.
The pronunciation of each experiment's number is typically by digit (e.g. Stitch is "Experiment Six-Two-Six"), with the only known exceptions being those whose numbers are divisible by 100 (e.g. Spooky is "Experiment Three Hundred"). According to some episodes of Lilo & Stitch: The Series and the "wanted posters" in the exit halls of Stitch's Great Escape!, the official abbreviation of "Experiment" (when referring to a specific one of such) is "X-" (X with a hyphen); in this format, Stitch's number would be abbreviated as "X-626" (pronounced as "ex six-two-six").
The experiments serve as the main plot devices of Lilo & Stitch: The Series, where Lilo and Stitch have to find the experiments (who are initially shown as dehydrated pods that are activated in water), capture them, name them, and rehabilitate them by putting them in occupations where they can use their abilities to help out society (referred to by Lilo as the places where they truly belong or "one true places"). Stitch, inspired by Hawaiian terminology, refers to nearly all of his fellow experiments as his "cousins" (Angel, his girlfriend, being the lone exception) and considers them all a part of his ʻohana. The original 626 numbered experiments, ranging from X-001/Shrink to X-626/Stitch, had their given names shown alongside Leroy & Stitch's credits.
About 100 experiments were designed for Lilo & Stitch: The Series, which initially was not intended to feature the other 625 experiments made before Stitch. Lilo & Stitch: The Series executive producer Jess Winfield 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. Over time, the idea of the Stitch clones would change to the 625 experiments before Stitch after someone else suggested them instead. Winfield did not 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.
Stitch & Ai—which does not feature any of the original experiments besides Stitch—features an entirely new set of experiments based on creatures from Chinese mythology.

#### List of experiments

Since the majority of experiments were never seen, this list will only focus on those who made significant appearances in official Lilo & Stitch media, such as having been a featured experiment on an episode of Lilo & Stitch: The Series and/or Stitch!, making multiple recurring appearances, or having a spoken role.
* X-001/Shrink – A small, purple, three-legged, levitating experiment who can fire a ray to change the sizes of objects and creatures. Unvoiced in his first appearances, he was voiced by Keith Silverstein in the anime episode "Experiment-a-palooza".
* X-002/Doubledip – A purple opossum-like experiment designed to double-dip food. He lives with Mrs. Hasagawa as one of her "cats".
* X-007/Gigi – A white Shih Tzu-like experiment designed to annoy people with her constant barking. She was found and adopted by Mertle Edmonds, who named her "Gigi", as her "dog"; Lilo nicknamed the experiment Yapper, hence the title of that episode. In Leroy & Stitch, she is revealed to be capable of speaking English. She was voiced by Tress MacNeille.
* 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". Both of his names are references to the lead characters of The Odd Couple. Felix also appears as a playable character in Disney Stitch Jam and a costumed character in Disney Parks, usually in events with other experiments.
* X-020/Slick – A pink, fast-talking, Southern-accented experiment who is designed to be an effective salesperson who is able to sell anything to anyone. His "one true place" is to serve as a fundraiser for charity. He was voiced by Jeff Bennett.
* X-022/Hertz Donut – A green seahorse-like experiment who can confine others by firing toruses at them, preventing them from moving. He was introduced in the Stitch! anime.
* X-025/Topper – A small, yellow, star-shaped experiment who is designed to be a beacon to signal an alien attack fleet, although the official Disney website previously stated his purpose is to keep people awake with his bright light. He is given to a little girl as a Christmas present. His number refers to Christmas Day (December 25).
* X-029/Checkers – A yellow and purple centipede-like experiment that sits curled up like a crown on people's heads, making whoever wears them a ruler who hypnotizes people around them (except higher-numbered experiments). The victims retain their normal personality while under its control, and the effect immediately wears off once Checkers is removed. His "one true place" is serving as a decorative crown for festivals. He was unvoiced in The Series but was voiced in the anime by Dave Wittenberg.
* X-032/Fibber – A small, orange, large-headed, four-eared experiment who is designed to detect lies. If he hears someone tell a lie, he buzzes loudly and the marking on his forehead glows. He was voiced by Jeff Bennett.
* X-033/Hammerface, also known as Hammerhead – A blue-gray dinosaur-like experiment who is designed to drive in nails around Jumba's house with his hammer-shaped head/face, but at times he will pound living things. He was voiced by Jeff Bennett in The Series and Steve Blum in the anime.
* X-040/Backhoe – A gray mole-like experiment with large black claws. He is an efficient digger designed to scrape up vegetation.
* X-054/Fudgy – A blob-like experiment made of chocolate who is designed to drown people in his sticky sweetness. In the Stitch! anime, Fudgy was modified by Hämsterviel to grow larger in size by eating chocolate. He was voiced by Rob Paulsen in The Series and Dave Wittenberg in the anime.
* X-062/Frenchfry – A small, grey and white, French-speaking, chef-like experiment who was designed to be Jumba's personal chef, instantly preparing food for him. However, 062 made unhealthy foods that quickly made people fat, then he ate the fattened victims. He stopped when he learned that healthy foods could be just as delicious, and would open a healthy French fry hut as his "one true place".
* X-074/Welko – A pink balloon dog-like experiment who can generate indestructible bubbles. She was introduced in the Stitch! anime, where she was voiced by Stephanie Sheh.
* X-089/Skip – A small purple hourglass-shaped experiment who was designed to skip time by ten minutes, but an error in his programming causes him to skip time by ten years instead. Skip has a reset button on top of his head that reverses time back to when his ability was first activated. He was voiced by Jeff Bennett.
* 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. He was voiced by Rob Paulsen in The Series and Roger Craig Smith in the anime.
* X-112/Toons – A yellow platypus-like experiment with an orange mane and a rectangular vacuum-like mouth who can bring 2D images to life by consuming a 2D subject and spitting it back out, making it 3D. He was introduced in the Stitch! anime.
* X-113/Shoe – A green and white sloth-like experiment with horseshoe-like horns who can control luck. His "one true place" is at a golf course, where he makes people score holes-in-one.
* X-120/Snafu – A small, teal, octopus-like experiment who is designed to foil enemy plans by any possible means. He is named after the military acronym SNAFU.
* 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. He was introduced in the Stitch! anime.
* X-123/Carmen – A pink, four-armed experiment who resembles Angel and wields four maracas. She is designed to make people dance until they drop by firing pink energy balls out of her maracas at victims. She first cameoed in Leroy & Stitch and later made a full appearance in the Stitch! anime, voiced by Kari Wahlgren.
* X-128/Bugby – A green, mosquito-like experiment who was designed to turn whole civilizations into harmless insects. Anyone turned into an insect can understand all other insects and arachnids. The only way to reverse the effect is with a machine built by Jumba. Bugby was later reprogrammed to only turn inanimate objects into insects. His "one true place" is helping farmers by creating ladybugs, who eat aphids. He was voiced by Grey DeLisle.
* 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-145/Bragg – A yellow, long-eared, cat/rabbit-like experiment who is designed to play music (primarily the flute) from Jumba's home planet, growing and increasing his strength through the sympathy he receives from his music. However, he also grows meaner and uglier the more powerful he gets. This experiment was introduced in the Stitch! anime, where he was stated to have been transmutated by Dr. Hämsterviel. He was voiced by Ben Diskin.

## Characters introduced in Lilo & Stitch: The Series
### Angel (X-624)

Angel (Experiment 624) is a pink female experiment who is Stitch's love interest with a great feminine resemblance to him. Stitch is madly in love with her and she shares the same feeling; they call each other their "boojiboo", a word in their native Tantalog language that is analogous to "mate". Angel can hypnotize others (mainly experiments made before her) by singing a siren song that converts them from good to evil, or vice versa when she sings her song backward. However, she can not hypnotize experiments created after her, including Reuben (625) and Stitch. In the anime series Stitch!, she is a famous singer who triumphs worldwide. She is voiced by Tara Strong in Western-produced media, and by Kate Higgins in the anime's English dub. She was designed by Jose Zelaya, an El Salvador-born character designer working at Disney Television Animation.
Angel becomes a much more recurring character in the Stitch! anime series, having become a successful pop singer since the events of Leroy & Stitch.
She also previously made an extremely brief, non-speaking cameo appearance in Stitch's Great Escape!.
Despite her limited appearances in Lilo & Stitch: The Series, Angel became one of the franchise's most popular characters. As a result of her popularity, she began making costumed character appearances in the Disney Parks in 2006, mostly at Tokyo Disney Resort and Disneyland Paris, usually appearing with Stitch. On February 14 (Valentine's Day), 2021, she began appearing at Disney's Aulani resort in Hawaii. Various merchandise featuring her likeness have been sold globally, including in the United States where the anime that she appears more frequently in aired only briefly on Disney XD; this has included merchandise with Walt Disney World and Disneyland branding, and a dedicated character page on the Disney Store website. She has also appeared in various video and mobile games, including Line Corporation's Disney Tsum Tsum, Bandai Namco's Disney Tsum Tsum Festival, Gameloft's Disney Magic Kingdoms, Disney Getaway Blast, Disney Speedstorm, and Disney Heroes: Battle Mode, while a plush toy of the character appears in the third episode of Monsters at Work.

### Experiment 627

After growing fed up with Stitch's constant bragging, Jumba decides to create Experiment 627, a red, koala-like, cone-headed experiment that possesses not only all of Stitch's abilities but also those of at least 20 other experiments and none of their weaknesses. Unlike the other experiments in the franchise (with the possible exception of Leroy), 627 was designed to be irredeemably evil with no possible way of turning good. Because of this, he was never given a name or a place where he belonged.
After being activated, 627 immediately breaks out of Jumba's ship and flees into the surrounding jungles, eventually stumbling across Reuben and attacking him before stealing and eating his sandwich. Eventually coming into contact with Gantu, 627 became his second-in-command and quickly got to work on capturing the experiments whilst also repeatedly humiliating Stitch with his superior abilities. However, he is ultimately defeated as Stitch exploits a flaw in his programming; he has an "extra" sense of humor and will collapse if he laughs too much. He is then dehydrated into his pod form.
In 627's only anime episode, Hämsterviel acquires and reactivates 627, who is also reprogrammed to speak a wider vocabulary (he only said "Evil!" in his original Western appearance). He disguises him himself as a human duke to lure Angel to a fake castle and use her to lead Stitch into a trap. He nearly succeeds until Jumba recalls his original flaw, and Stitch and his friends exploit it again. He then saves Stitch and his friends from Hämsterviel's castle (which was also a rocket), and then Stitch and Angel from being crushed by Hämsterviel's spaceship, though only because, as 627 self-declares, that only he gets to destroy Stitch. He then leaves Earth by taking a space scooter meant for Gantu.
627 has also appeared as a costumed character in Disney Parks, usually with other experiments.

### Victoria

Victoria is a friend that Lilo meets in the second season of Lilo & Stitch: The Series. In her first episode, "Swapper", she had just moved into Kokaua Town, also joining Lilo's hula class. When she and Lilo were becoming friends, Mertle tried to befriend her so that she would not be Lilo's friend, claiming that she was weird. However, despite Mertle's best efforts, Victoria reveals that she also liked weird things and decided to become Lilo's best (human) friend, to which Mertle angrily responds by saying, "We would never tolerate with anyone who actually has fun with Lilo." Following the agreement from the other girls, Mertle then ditches Victoria who happily remains with Lilo.
Victoria's appearance in the series is very short. She then appears briefly in the episode "Slick" where she, Lilo, and the other girls compete against each other to sell the most candy bars for their hālau hula.
Then in "Snooty" (the only episode where she and Lilo are actually seen hanging out together), she becomes frightened of Experiment 277 (Snooty), a bat-like experiment who she mistakes for a vampire. After Lilo discovers it's an experiment she tries to convince Victoria not to slay it, but to catch it and try to make friends with it, pointing out that the experiments can be turned from bad to good. But after it puts Stitch out of commission she refuses to believe Lilo and decides to team up with Gantu to slay the experiment. Later, however, after Lilo shows up and saves her from Gantu she realizes her mistake and saves Snooty from Gantu. Furthermore, when Snooty shows a notable ability to clear out Victoria's often-clogged sinuses, she decides to keep him as a pet.
In "Remmy", she appears with Mertle and the other hula girls in Lilo's dream where they all treat her nicely at first, but then she begins to treat her as badly as the other girls when the dream turns into a nightmare.

### Other recurring characters

* Mr. Wong (voiced by Clyde Kusatsu): The owner of the rental hut on Lahui Beach and Nani's employer in early season one. He is quite demanding of her working at his hut when and how he wants her to, such as having her work on her day off when an earthquake messed up the hut, but he is otherwise understanding and forgiving when she has to deal with her personal troubles.
* Mrs. Edmonds (voiced by April Winchell): Mertle's mother. Unlike her daughter, she is kind to Lilo. However, she also spoils her daughter heavily, to the point where Mertle even gets to celebrate "half-birthday" parties.
* Keoni Jameson (voiced by Shaun Fleming): A young, laid-back boy who enjoys skateboarding and 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.
* 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.
* Officer Kahiko (voiced by Kevin Michael Richardson): A police officer who knows Lilo well and occasionally tries to keep her out of trouble when she isn't accompanied by Nani.
* Aunt Stacy (voiced by April Winchell): Mertle's aunt. She's a Hollywood producer and she strangely cannot remember Mertle's name.

## Characters introduced in Leroy & Stitch
### Leroy (X-629)

Leroy (Experiment 629) is Stitch's evil twin brother who is created in Leroy & Stitch. He has red fur, frilly ears, yellow teeth, bent antennae, three bent spines on his back, a fluffy tail, and a slightly deeper voice as well as two extra, retractable arms and retractable claws on his front paws. Jumba started creating him from a template similar to Stitch until Dr. Hämsterviel captured him and forced him to make a "new version" of 626 (Stitch). He is designed to have all of Stitch's powers, but he also has the ability to disguise himself as Stitch by changing his fur from red to blue. He is voiced by Chris Sanders.
As of June 2020, Leroy's only other appearance in the Lilo & Stitch franchise proper has been in the second chapter of a two-chapter Disney Tsum Tsum-themed side story of the manga Stitch & the Samurai that was released via the Japanese version of the Disney Tsum Tsum mobile game for a limited time throughout that month. Notably, the manga was the first Disney media to number Leroy as Experiment 629, although the second chapter of the side story was not published in English; the number would be proclaimed for English-speaking audiences the following year through a Disney-licensed sticker book revolving around the franchise.

## Characters introduced in Stitch!
### Yuna Kamihara

Yuna Kamihara (上原ユウナ, Kamihara Yūna) is a tomboyish 4th-grade (later 5th grade in the third season) student who lives on a fictional island off the shore of Okinawa in the Ryukyus called Izayoi Island. Living on Izayoi Island, she practices and teaches karate, having learned it from her grandfather. Her grandpa also did the honor of giving her a special type of moonsand as a good luck charm in her study of karate before he left.
During the Madhouse-produced first two seasons, she lives a rather normal cherished life with her grandmother. Her parents are absent in her life; her father is out at work a lot as a marine biologist around Okinawa, and her mother died when she was an infant. Her life remained normal yet happy until one day, after a varied coincidence, she meets Stitch, who crash-landed on her island after he got caught in a wormhole that sent him to Earth. From then and there when they met, the two became best friends and the duo went on various adventures on Stitch's quest in order to be "good". Yuna though, throughout the majority of the anime, finds friends like Taro, Sasha, JJ, Tombo, yōkai like Kijimunaa, and even in experiments like Angel. Her strong sense of justice is what makes her a tomboy, which shows against evildoers like Dr. Hämsterviel and against rivals like Penny and her gang of bullies.
In the Shin-Ei Animation-produced third season, she and Stitch move off Izayoi and onto the fictional Okinawan city of New Town to live with her cousin Tigerlily there, at the behest of Yuna's grandmother. (A flashback scene in the Japanese original version of the season's first episode states that it is mainly because Izayoi Elementary School is about to close down after one last school year.) She becomes a student at New Town Elementary School and continues to go on adventures with Stitch in the city.
The creators of the anime got Yuna's name from the Japanese name of sea hibiscus out in Okinawa (known in Japanese as Yuna). Yuna's birthday is on February 25. Yuna's surname Kamihara wasn't unveiled until much later, although previous guesses were Chitama, after the dojo and the forest on Izayoi and Hanako, which was Yuna's previous name and design during the development of the anime.

### Gramma

Gramma (おばあ, Obaa) is Yuna's grandmother who raises her on Izayoi Island during the show's first two seasons. She is a kind, patient, elderly woman who is very knowledgeable about yōkai and the spiritual side of the island.

### Kijimunaa

Kijimunaa (キジムナー, Kijimuna) is a little yōkai, who is Yuna and Stitch's friend. He is kind of a coward, but with the help of his friends, he can find the courage to best whatever he can.

### BooGoo

BooGoo (ブーグー) is a mysterious purple alien insect with some shapeshifting abilities who is introduced in the debut episode of the second season, becoming a pet to the alien side of Yuna and Stitch's family. She is considered cute and is beloved by everyone except for Stitch, who finds her to be a nuisance, especially since she tends to eat food off of him, often by tricking him into looking away while he's eating or about to eat.
In her debut, she was found by Dr. Hämsterviel, who sends her to Izayoi Island to mess with Stitch's good deed counter, causing it to count good deeds as "bad" (and thus removing "good deed" points) and bad deeds as "good" (and thus adding points). She was found by Pleakley, who mistakes her to be a kind of fruit fly, and was discovered by Jumba to have been enslaved by Hämsterviel using a controlling device, which Jumba then removes, freeing her. Afterward, Jumba repairs Stitch's good deed counter, and BooGoo joins Yuna and Stitch's family.

### Tigerlily Sakai

Tigerlily Sakai, named Zuruko Sasuga (さすがつるこ, Sasuga Zuruko) in the Japanese original, is Yuna's beautiful but mean and bullying cousin who appears midway through season 2. While she seems to be kind-hearted to others, she is harsh and cruel to Yuna for unknown reasons and constantly blackmails her into doing all the chores around the house (although she later claims that she's only trying to be a role model for Yuna). However, when Yuna and Stitch move off to live with her in season 3, she becomes more friendly with Yuna and treats her nicer, although she still forces her to do most of the house chores.

### Delia

Delia (デリア) is an evil alien woman who appears in season 3. She is in a partnership with Dr. Hämsterviel to get the Neo-PowerChip that is inside Stitch. Delia alters a majority of experiments, which causes them to become physically stronger and evil, as well as Angel who is rescued by Stitch. Delia usually calls Dr. Hämsterviel by false names or pronunciations. When Dr. Hämsterviel's plans go wrong she eventually punishes him with various explosions or robots.

### Dark End

Dark End is an experiment made by Delia who is designed to be much stronger than Stitch. This experiment is female in the original Japanese version and male in the English dub. They are not among Stitch's cousins, as neither Jumba nor Hämsterviel made them.

## Characters introduced in Stitch & Ai

### Wang Jiejie

Wang Jiejie (王婕婕; Wáng jié jié) is a young Chinese woman who is Ai's older sister.

### Daiyu

Although her belief that her actions are what's best for Ai are similar to how Cobra Bubbles (who also appears in this series) was considering what's best for Lilo in the original Lilo & Stitch film, Daiyu is otherwise unique to this series, having no counterpart from the original Western continuity.

### Meiying

Meiying (美英; Měiyīng) is Ai's rival. Although she serves as this series's counterpart to Mertle Edmonds, she is considerably friendlier towards Ai than Mertle was towards Lilo.
