In the animated television show Lilo and Stitch: The Series, experiments are creatures that were created by scientist Dr. Jumba Jookiba. It is unknown how long it took to create these experiments (only Experiment 626 was revealed in the original movie), but a little white alien named Dr. Hämsterviel wants them back. He hires Captain Gantu to capture them and bring them back to him and the team of Lilo and Stitch don't always get them but they do most of the time. Stitch refers to the other experiments as his "cousins".

Essentially Jumba thought of everything bad that can happen to someone, and made it into an experiment. There is an experiment with the power to make people sick (Experiment 222; Poxy), an experiment that can cause earthquakes (Experiment 513; Richter}, and an experiment that can practically cause another ice age (Experiment 523; Slushy).

There are some experiments that aren't so bad. Jumba created a lie-detector experiment (Experiment 032; Fibber), and an experiment that can destract an enemies by stretching his body like taffy (Experiment 345; Elastico). There is also an experiment who stinks for an hour but he has irresistible cuteness 254 (Mr. Stenchy) and there is an experiment that drives people crazy whith her never ending yapping. (007, Gi-Gi) and 625. Experiment 625 is suppposed to have all the powers of Stitch but this detail is not part of his programing (He never uses them - he is too lazy to; he makes sandwiches)

Lilo gave the experiments their names such as Poxy, Felix, Yaarp, Splodyhead, Bonnie, Clyde, etc.

An inactive pod is an alien experiment from the Lilo & Stitch television series that has not been activated. Some examples include Experiments 567, 607, 611, and 628.

This article also includes experiments that have very little information on them. (e.g. Experiment 119)

List of Experiments

Experiment 007 - Gigi

007 looks like a dog. She looks a little like a Shih Tzu. Her main power is to drive everyone crazy with her never-ending yapping.

In the episode where she is revealed, Gigi is adopted by Mertle. Mertle challenges Lilo to a dog show in Honolulu. At the dog show, Stitch seemed to be doing well until Gantu showed up to capture 007. Stitch saved 007 then everyone chanted "best in show, best in show!". Afterwards, as a thank you, Mertle gave the best in show award to Lilo.

Experiment 010 - Felix

010 is green with a brush on his tail and a vacuum-like nose. He is designed to sterilize, disinfect, and clean everything in sight.

In the episode where he is revealed, Lilo and Stitch are playing around and things get dirty. Nani tells Lilo to clean up. However, she doesn't want to clean up. That's when Jumba tells her about 010.

They soon find and capture 010 cleaning up at the beach. They ask him to clean up their house, and then the building where hula school is located. 010 tries to clean a carpet but he can't. He starts malfunctioning and makes everything dirty instead of clean.

Felix is most likely named after Felix Unger, a character from the play/TV show The Odd Couple.

Experiment 010.2 - Oscar

Appears in the same episode as Experiment 010. Oscar is a reprogrammed version of Felix, who now makes messes instead of cleaning things up.

Oscar is most likely named after Oscar Madison, a character from the play/TV show The Odd Couple.

Experiment 025 - Topper

025 is a small, star-shaped creature. His power is being a beacon to the experiment attack fleet.

In the episode where he is revealed, Topper tops the local Christmas tree, and emits a light so bright that aliens from other galaxies can see it from Earth. He is revealed in what is the christmas episode of the series.

It is believed that this experiment got its number from the date of Christmas (025/December 25).

Experiment 032 - Fibber

032 is small and orange and he is red. He may not be much of an evil experiment, but his power is that he can beep loudly every time someone tells a lie.

In the episode where he is revealed, Pleakley's mother insists that he find the right wife, but it turns out to be Nani! Nani, however, objects to marrying Pleakley. Gantu eventually captures 032, and Pleakley's wedding turns out to be all a big lie.

Experiment 033 - Hammerface

033 is gray with a hammer-shaped face (thus the name Hammerface). He's designed to drive in nails around Jumba's house. Sometimes he'll pound you with its head, too. Later re-named Hammerhead by Lilo. (re: THE ASTEROID)

He was revealed in the same episode as Thrasher, Dupe, Heat, and Plasmoid. Dupe replicated him 100 times over; however, this resulted in the original Hammerface only having 1/100th of his power and energy. This experiment aparently was later reintegrated by Dupe. (re: THE ASTEROID)

Experiment 062 - Frenchfry

Is a small grey coloured creature with a spatula for a tail, has a mustache, speaks with a French accent, and the top of his head is shaped like a chef’s hat. This experiment was originally intended by Dr. Hämsterviel personal chef. However, the food prepared by him was without any nutritional value and super-fattening, which makes them huge bowling balls. Once they are very, very fat, Experiment 062 will eat them.

Experiment 119 - Chocolate

Experiment Number 119 is an experiment from the Lilo & Stitch television series.

119 is mistaken for 611, a sort of weapon of mass destruction. 119 is a really chocolate experiment. He is designed to smother you with His chocolatey goodness.

Experiment 151 - Babyfier

151 is a small, pink creature with a big head, and a pacifier in his mouth. He is designed to, with his baby rattle-shaped tail, emit a pink powder which can disable planets by turning adults into babies.

In the episode in which he is revealed, Lilo gets in trouble when she goes to a movie that she was told not to see. Lilo wishes that she was the oldest so she can see the movie. While walking home, she and Stitch discover and capture 151.

Afterwards, Stitch decides to grant her wish. Stitch releases 151 and he uses his power on Stitch, Nani, Jumba, and Pleakley. Lilo is surprised when she discovers the adults turned into babies.

She soon realizes she has a problem on her hands, she has to take care of four babies. Meanwhile, 151 is captured by Gantu then Gantu himself is turned into a baby! 151 escapes and turns the entire island into babies. Lilo and Baby Jumba finally discover how to reverse 151's power. They have to use applesauce, bananas, and 100% kona coffee. However, he must be an adult to buy that kind of coffee.

Jumba and Pleakey break into the store and get the kona coffee. Lilo and Stitch collect the apples and bananas. Stitch once again saves the day when he shoots the mixture into the sky and turns the entire island back to adults.

Lilo and Stitch finds 151's one true place at the dog pound making older dogs young again (thus making them more appealing to potential adopters).

Experiment 158 - Finder

158 looks like a red anteater. His primary power is that he can find anything and everything. When he finds something he honks.

In the episode where he is revealed, Dr. Hämsterviel escapes from prison and heads for Earth. Meanwhile, Lilo & Stitch discovers Finder. When they discover that Dr. Hämsterviel is on Earth, everyone sets out to find Hämsterviel; however, they come up to a fork and Stitch says they should go one way and Finder says they should go another.

They don't find Hämsterviel until Mertle finds him. And when they find him, Mertle and Dr. Hämsterviel are captured by Gantu (the Grand Councilwoman tells Gantu that she can reinstate his captain rank if he captures Hämsterviel). When it is discovered that Gantu put an innocent girl in danger, the Grand Councilwoman takes back her offer. Lilo then asks her to let Dr. Hämsterviel stay with Mertle for one day so that she can take him to school for Show-And-Tell. The next day, Mertle's friends at school are fascinated as she shows off her "talking gerbil".

Experiment 177 - Clip

177 looks like a small yellow hairball. She also has a pink bow and long scissor-like claws. She's designed to eat hair.

In the episode where she is revealed, we learn that 177 was originally created to eat uburnium, a priceless and abundant fuel used in outer space. Jumba created the experiment originally to eat all of the uburnium and cause a fuel crisis. However, it turned out that in Jumba's native language, "uburnium" sounds like or is the same word as "hair". So the experiment ended up eating Jumba's hair instead of the uburnium.

Lilo used 177 to punish Mertle for saying she had "wild, unruly hair". Lilo and Stitch sneak into Mertle's room and hides 177 under her pillow; however, Mertle was on a sleepover at the time. Gantu tries to capture Clip, but at the same time Mertle's mom walks into her room. Clip jumps on her head, cuts off all of her hair and eats it. Mertle's mom faints. Clip hops off onto a bus and starts cutting off the hair of Kokaua Town residents.

Clip is finally captured when Lilo uses some shampoo to separate Clip's hair (if she eats too much hair, Clip's hair starts to grow wildly). Lilo and Stitch finally find Clip's true place at the beauty salon.

Experiment 199 - Nosy

199 is experiment with a pig-like figure body and a big nose. His power is to reveal your most embarrassing secrets. He was revealed in the series when Lilo wants to impress Keoni Jameson, her crush. He was later caught by Gantu but he revealed secrets about him to Dr. Hämsterviel. He apparently was able to later escape from Gantu as he was show to be again on the loose in a later episode (Spike) Gantu thought that this experiment would tell him all Lilo and Stitch's experiment files, but soon found out that he only talks about useless information.

Experiment 221 - Sparky

221 is a small, light yellowish creature that resembles a Chinese dragon. His power is that he can create crippling electric surges.

221 is first revealed in Stitch! The Movie. With the other experiments, he is unknowingly released during the battle between Lilo and Gantu. He makes a few appearances in the TV series. During the Angel episode he is turned evil. In "The Asteroid" he helps to destroy the asteroid. In the Elastico episode he fixes Lilo's jewelry. He also appears when all the experiments come together to make one massive super experiment.

Experiment 222 - Poxy

222 looks a little like a cell. This experiment is designed to bring down popular planetary leaders by getting inside them and giving them a disease. The symptoms are purple pimples, smelly feet, and uncontrollable burping.

In the episode where he is revealed, Pleakley ends up catching 222; however, he has purple pimples, smelly feet and burping, but his eye is swollen. The only way 222 can be captured is if Lilo and Stitch go inside Pleakley's body and find the experiment. They use a shrinking ray to go inside Pleakley's body.

They catch the experiment but they must get out before the shrinking ray's power wears off. They eventually get out but Gantu shows up. Experiment 222 escapes and Gantu catches the disease-like experiment. Poxy's true place was inside Gantu.

Experiment 228 - Melty

228 looks sort of like a small red dragon. It has the power to melt enemy fortresses, weapons, and transportation.

In the episode where 228 is revealed, Lilo and Stitch go back in time with a time-travel surfboard to prevent 228 from melting the hotel where Nani works. They end up having to go to the past at least six times before they finally get their experiment.

First 228 melted the hotel and a tree fell in the parking lot. On the third time, a ship crashed into the hotel. On the fourth time, they forgot to turn on the paradox inhibiter (the function that prevents two of the same person appearing at the same time). On the fifth time, Melty caused a tidal wave. On the sixth time, they seemed to get it right, but Gantu captured Him and Melty destroyed Lilo's house. A future Jumba helped Lilo restore the timeline, in which Lilo had to embarrass herself.

Experiment 254 - Mr. Stenchy

254 is cute but he stinks.

Mr. Stenchy is mainly designed to trick his enemies into taking him to their house. Once there, Mr. Stenchy lets out his terrible stench.

In the episode where he is revealed, we learn that the noxious odor is released 42 hours after activation. We also learn that the experiment's odor is used as a perfume on the planet where Pleakley is from. At the end of the episode, they send Mr. Stenchy to Pleakley's planet.

Experiment 258 - Sample

258 has big ears like speakers and is bright orange. His main purpose is to play back random sounds in a loop to annoy his enemy. His one true place is with a band which had terrible rhythem at first, Samples music has a catchy beat.

Experiment 297 - Shortstuff

297 was activated at a carnival after Stitch destroyed a lemonade stand. This experiment resembles a crab, and is designed to destroy machinery by going inside and cutting the mechanism and electrical wiring with his four claws. This experiment's squat size is the reason Lilo named named him "Shortstuff."

Experiment 300 - Spooky

300 is a small, green blob. His primary function is to scare the bejabbers out of people by morphing into their worst fears.

300 is revealed during Halloween. It becomes known in this episode that Stitch is not entirely fearless. He is scared of water. 300 morphs into a roomful of water to scare Stitch. When Lilo found him, he was muttering, "Hissing green eyes." Afterwards, Lilo & Stitch go into the old abandoned house to find Spooky. While they're there, Stitch finally stands up to 300 and captures him.

Experiment 303 - Amnesio

303 is a small, insect-like creature. He's silver and has big eyes. His special power is that he can erase people's memory. He moves just by flying.

In the episode where he is revealed, Gantu tried to capture 303. He was given amnesia by 303 along with Lilo and Stitch. Lilo spoke the password, "ohana!", to reverse his powers. After Lilo's birthday party, he was given to Dr. Hä;msterviel.

Experiment 319 - Spike

319 looks like a gray porcupine. His special power is that he can reduce the victim's IQ buy 99%. In the episode he is revealed in, Lilo wants to win the oama rama, but Mertle cheats. Later when Spike is good, Lilo and Stitch use Spike to get Teresa (Mertle's frend) so Mertle would not cheat. Lilo wins the oama rama and Spike gets Mertle.

Experiment 323 - Hunkahunka

323, also known as "Hunkahunka" by Lilo, is a little pink experiment. When 323 pecks people, they fall in love with the next person they see. Eventually this results in widespread chaos, as everyone keeps falling in love with everyone else. 323's effect is remedied by a spray of water in the face.

Lilo uses 323 to make Keoni Jameson, on whom she has a crush, fall in love with her. Soon, however, she realizes that she wants him to love her for who she is, not because he got pecked by a "genetic mutant experiment bird", as she likes to call them. She learns a lesson about meddling with the laws of love. Gantu takes 323, but Lilo lets him get away.

Hunkahunka is mostly likely named after a lyric in the Elvis song, "Burnin' Love".

Experiment 344 - Dupe

344 is a small creature with light brown fur and dark brown stripes (She looks a little like a raccoon). Her special power is that he is able to generate clones with an appendage on her head; however, the clones tend to have less of whatever the original had. (For example, with food, the duplicates tend to be low-calorie or low-fat.)

In the episode where he is revealed, Lilo uses Dupe to generate clones of Stitch. Dupe made 3 clones of Stitch. They only had a small amount of the strength and agility that the original had.

Experiment 345 - Elastico

Elastico is green, earless, monkey-like creature without a tail, with a white face and large red nose. He moves around like he was made of rubber. Elastico is not considered dangerous; he is designed to distract enemies. In one episode, Stitch found him performing at a circus and his clownish antics were a big hit with the audience. Stitch briefly replaced him after Gantu captured the rubbery experiment (who literally oozed out of his containment cell and returned to the big top). Much like ShortStuff (297), Elastico's true calling was entertainment.

Experiment 149 - Bonnie

349 is green and she's smaller than Stitch. Her only power is that she can steal things, even the clothes off your back without you knowing, She is found with 150. Bonnie is the only female experiment that has been revealed so far that can speak English.

In the episode where she is revealed, she is activated with 350 by a policeman. When they are activated, they steal the policeman's clothes then drive off in his squad car. Meanwhile, Lilo and Stitch are being a little unruly at their house. Nani grounds them for the day and Stitch decides to escape. Afterwards, they meet 149 and 150.

149 tells them that they had trying to break into Gantu's ship. Lilo tells her that she and Stitch had broken into her ship. 149 then lets Lilo and Stitch help them break into Gantu's ship.

149, 150, Lilo, and Stitch end up nearly wreaking havoc all over town (such as ripping up the grass in the park and stealing it, throwing toilet paper at Mertle's house and stealing fruit from Mrs. Hasagawa) Afterwards, they learn they must capture 349 and 150. In the end, Lilo and Stitch captures them and 349 and 350 end up in prison serving hamburgers.

Bonnie is most likely named after bank robber Bonnie Parker.

Experiment 150 - Clyde

150 is a chartreuse-colored experiment that is bigger than his stealing counterpart, 149. 150 tends to be the muscle of the duo. His power also is to steal. His right hand is a sort of gun.

150 is also activated with 149.

Clyde is most likely named after bank robber Clyde Barrow.

Experiment 360 - Drowsy

Drowsy is a experiment that looks like a sheep. Drowsy is designed to put people to sleep when he says "baaaaa". Nani said if Lilo did not get to places on time and get some sleep there would be no more experiments. Stitch used Drowsy to put her to sleep. They won a ticket to show a man to his hotel and to their surprise it was Regis Philbin. Drowsy's one place that it belonged was a job was at the hotel putting people to sleep.

Experiment 375 - Phantasmo

Experiment 375 is a phantom-like experiment that can inhabit and animate inanimate objects. It gets loose in the family's house, inhabits Lilo's toys and creates all sorts of mess, for which Stitch gets the blame. In the end Phantasmo is 'caught' and works at the Macky Macaw as Macky Macaw.

Experiment 390 - Slimy

In the episode in which he is revealed, he is activated with Yang. Jumba said that should these two experiments touch each other, they will cause a giant explosion of end of the world proportions.

In the end, they use a good example of Yin and Yang, two things coming together to create something new. In their example, they use fire and water to create a new island.

Experiment 502 - Yang

502 is a red creature. He looks like a big bug on four legs, however his body curves in the middle. His special power is that he can sprout magma.

He is revealed in the same episode as Yin.

In the end, 501 and 502 are a good example of Yin and Yang, two things coming together to create something new.

Experiment 509 - Sprout

509 is a plant-type experiment with a green stem and leaves-like body and a purple face. He's designed to sprout into an uncontrollable forest of destruction.

In the episode where he is revealed, Lilo wants to enter the fair in town. She wants to enter a plant or a flower into one of the events when Jumba tells her about Experiment 509. But he also tells her that he knows what he can do so he locks the pod in a drawer.

Stitch enters a rodeo competition. Lilo steals Experiment 509's pod and activates it. She enters him into the plant and flower competition at the fair.

At the competition, Mertle removes 509 from his pot. Soon after, 509 starts to grow uncontrollably. Lilo and Stitch attempt to get him under control. When Jumba finds out that Lilo has taken Sprout he rushes to the fair to find Lilo.

To get Sprout under control, Lilo and Stitch take some electronic gardening supplies to stop him. Lilo and Stitch end up catching him (after he has grown a lot) and put him in an old water tower which looks like a pineapple and was also going to be torn down.

Experiment 523 - Slushy

523 is a small, ice colored creature with three icicles on his head. He was created to freeze land with his breath.

In the episode where he is revealed, 523 chills things off in Kokaua Town during a very hot day. He makes it so cold that it starts to snow. 523 is captured for a short time. During that time, Lilo enjoys the snow that 523 creates (Stitch does not like snow because it is a form of water). Gantu captures 523 and tells him to build a giant ice castle.

While there, a battle ensues between [plasmoid]] and ice, Splodyhead (Experiment 619) and 523. However, it was plasmoid that won over ice this time around. Splodyhead shoots a heat beam into the sky and burns off the clouds and it becomes sunny again. Slushy finds his one true place at the ice cream shop creating shaved-ice.

Experiment 529 - Digger

Experiment 529 is also known as Digger. He was designed to dig holes. He was activated in Stitch! The Movie. His first appearance in the series was in "The Asteroid". He was also in "Elastico" when most of the experiments fixed Lilo's bracelet and in the episode where all the experiments come together to make one massive super experiment.

Experiment 544 - Thrasher

544 is small, dark blue creature with six ball-like tenticles and three legs. His special power is that he can thrash crops with his mace-like appendages.

He was revealed in the same episode as Experiment 344. He, Hammerface, Plasmoid, and Heat were all captured by Gantu. When Gantu found out about Dupe's power he decided to make an army of Thrashers, Hammerfaces, Plasmoids, and Heats. However, all of the experiment's powers were divided by the amount of replicants made.

Experiment 567 - inactive Pod

Experiment 586 - Tank

Experiment 586 was designed to eat metal. Each time he does he grows bigger.

The Hula Girls have ditched Mertle for Lilo, and consequently, Lilo neglects Stitch to hang with them at the Kauai Medieval Festival. When Experiment #586 is activated, Stitch needs someone to capture him with and he teams up with Mertle. Stitch and Mertle have fun trying to capture the metal eater, but this ends when it storms the Medieval Festival. Tank is eventually caught by Gantu and sent to Hämsterviel.

Experiment 601 - Kixx

601 is a purple creature with four arms. He was designed with special kickboxing skills. He may not be as strong as Stitch but he is still very strong.

In the episode where he is revealed, he is using his fighting skills against everyone on the island. Lilo and Stitch try to stop him but he easily defeats Stitch in their first meeting because Stitch ate macadamia nuts and with a left tennis shoe. This makes him sick and forget how to fight.

Now Lilo has to teach Stitch his fighting skills all over again. He finally learns and wants to run off to face 601; however, Lilo still has to teach him how to fight four-armed experiments, but it is too late. Stitch has already ran off.

601 is now wreaking havoc at the beach as he easily defeats all of the musclebound guys at the beach. As soon as Stitch gets there it is a battle of epic proportions. Kixx gets the best of Stitch until Lilo arrives. She tells him what to do to defeat Kixx, and they get their experiment.

They find 601's true place doing an infomercial, kickboxing.

Experiment 602 - Sinker

Sinker is a shark-like experiment that was designed to destroy and sink enemy ships with its large razor-like fin. Throughout the episode that Sinker is activated, he is constantly sinking and destroying boats and ships that are getting ready for an annual Aloha Boat Race competetion.

Lilo and Stitch finally catch Sinker after he causes their cruiser to stop before it hits the beach.

Lilo and Stitch find Sinker's true place at a Japanese restauraunt where he uses his large fin to cut up vegetables for the chefs.(RD)

Experiment 603 - Electric

A bright yellow living laser bolt. In the episode in which he is revealed, Jumba has created a 627. This new experiment is stronger than Stitch and therefore is able to captch some experiments as he meets Gantu. When 603 is caught, the bolt is tearing up a farm.

Experiment 604 - Houdini

604 looks like a rabbit with four brown spots on him (two spots are on his elbows and two are on his knees). His special power is that he can make anything disappear with a blink of his huge eyes. However, he can be startled easily and makes himself invisible.

In the episode where he is revealed, he is activated when Stitch cannot do any disappearing acts during a magic show. When he is revealed to the people, they take pictures of him and he goes blind temporarily. He blinks his eyes multiple times to try and return his eyesight but when he does that he makes everything in town disappear.

Experiment 606 - Holio

Holio is a fictional experiment that has red fur. He has a humongous mouth and when he opens it, it creates a matter sucking black hole.

Experiment 607 - inactive Pod

Experiment 608 - Slugger

Experiment 608 is designed to hit a home run or deflect projectiles.

After Pleakley's incompetence in baseball causes Lilo, Stitch, and Stitch's cousins to lose to Mertle's team, Lilo and Mertle arrange a rematch, with Lilo's collection of Elvis records and Mertle's collection of dolls on the line. Lilo finds Experiment #608, aka 'Slugger', and decides his projectile-deflection skills would make him an excellent pinch-hitter for her team. Unfortunately, Mertle gets her own ringer in Gantu, and makes the rematch a game of basketball instead of baseball, with Slugger on the line as well.

Experiment 609 - Heat

Gantu's Army - Heat, Plasmoid, Thrasher, and HammerFace were activated in the episode featuring Dupe. Gantu found their pods on sale and used them to kidnap Stitch.

Heat is shaped like 625, only red, with a large black oval on his forehead. From this oval the experiment can fire heat.

The army of Gantu was defeated when Lilo tricked Gantu into creating 100 of each experiment in his army. Thus, the power was divided by 100, allowing the 3 copies of Pleakley to defeat them.

Experiment 611 - inactive Pod

Gantu mistakes Experiment 611 for Experiment 119 (611 is 119 upside down). 611 is a missile or some sort of weapon of mass destruction experiment. He's a large black Stitch-shaped creature with four arms, jet engines for the wings, steel eyes and a long tail.

Experiment 613 - Yaarp

Yaarp looks a bit like Drowsy, but instead of sending people to sleep, his power is to make a sonic blast so loud she can make you be deaf. In the episode where she is revealed, Pleakley is sent to go after her, as he has no ears. At the end Pleakly saves Yaarp and they become friends. Yaarp becomes an experiment invasion alarm.

Experiment 617 - Plasmoid

617 is revealed in the same episode as Dupe, Thrasher, Hammerface and Heat. Plasmoid is designed to fire plasma blasts from its tail. Lilo never finds a home for 617 and he was sent to Dr. Hämsterviel.

Experiment 619 - Splodyhead

While in pod mode, 619 was carried by a bird to the Forbidden Island, where no one lives. Lilo and Stitch decide to go to the island to get 619 but they don't know that Gantu is also there. They meet fight and suddenly the ground moves and 619 gets activated. 619 starts to attack them with plasmoid balls from his "nose" (a hole in the middle of his head). Stitch and Gantu decide to work together to capture him. After that, Gantu takes the experiment but they realize their ship has beeb destroyed. Nani and David come to rescue Lilo. She makes a deal with Gantu to take him home in exchange for Splodyhead. Splodyhead now lights luau torches with David.

Experiment 624 - Angel

624 is a small pink experiment. She looks like a female version of Stitch. Her special power is that she can sing a siren song that is able to turn her cousins evil although she cannot do it to 625 or Stitch as they are after her. She and Stitch really love each other and she is the perfect girlfriend for Stitch.

Experiment 625 - 625

625 is a small, yellow creature that reminds people of Stitch. He has all the powers of Stitch, except he is so lazy he has never used them. He is also a glutton for sandwiches and unlike most of the other experiments, speaks English flawlessly with a hint of a Brooklyn accent.

625 is first revealed in Stitch! The Movie. He is accidentally activated by Lilo in a battle with Gantu. In the television series however, he is Gantu's sidekick. He may be Gantu's sidekick and his best friend but he is a good guy and was only evil for 1 or 2 seconds.

Experiment 626 - Stitch

626 is a blue creature who looks like a large mouse, bearing a remote appearance to a koala. His special abilities are that he has super strength (he can lift 3000 times his weight), is very mischievous and can think faster than a supercomputer. His only weakness is that he can't swim because he is very dense, therefore he will sink like a rock in water. Stitch really has six appendages, two of which are retractable, and antennae.

Stitch is first revealed in the movie. At first he is an evil alien experiment. He escapes from planet Turo, which is where the galactic council meets. He takes a spaceship and heads for Earth. He meets a little Hawaiian girl named Lilo who takes him in as a dog.

Experiment 627 - 627

627 was created to be better than Stitch. Jumba gives him all the strengths of Stitch, including twenty other experiments, but didn't give him any of his weaknesses. He is red, able to sprout six arms and an extra head and could only say, "Evil!" 627 could even unhinge his mouth like the xenomorph from Alien. He was captured by Gantu, who decided to use him as his new sidekick.

Eventually, Lilo learned of a device that is able to dehydrate anything instantly. She also learned that 627's only apparent weakness was an extra bad sense of humor. Lilo and Stitch exploited this and were able to defeat 627.

After 627 was deactivated, Jumba placed a blue pod in a storage safe aboard his spaceship. The pod has the number "628" on it, which will most likely be more dangerous than 627.

Experiment 628 - inactive Pod

At the end of the episode that revealed Experiment 627, Jumba mentions that he hopes to have more luck with 628. The experiment is activated and Jumba conceals him but he gets out in a later episode.
