X-151/Babyfier – A small, pink, infantile, koala/fairy-like experiment with a yellow pacifier in his mouth and a long baby rattle-shaped tail. He is designed to people into babies with a pink powder shaken from his rattle-like tail, the effects of which can only be reversed with a specifically mixed antidote. His "one true place" is at the animal shelter making older dogs young again, thus making them more appealing to potential adopters. In Stitch! ~Best Friends Forever~ (the anime's third season), he was reprogrammed by Hämsterviel to turn people into toddlers instead of babies and was renamed "Toddler-fier" in this appearance. Babyfier's pink, youthful appearance and experiment number may be a reference to the Pokémon species Mew, who itself is a pink, youthful creature numbered 151 in its franchise. He was voiced by Tara Strong in The Series and Laura Bailey in the anime episode "Toddler-fier" (he was unvoiced in "Link-age"). Despite her limited appearances in Lilo & Stitch: The Series, Angel became one of the franchise's most popular characters; a Disney Channel online poll held in Spring 2004 showed that Angel was voted by the show's viewers as their #1 favorite experiment and episode from the first season of the series. [19] Like Jumba, Hämsterviel is stated to be an evil genius as well, having graduated from the same "Evil Genius University" as his former partner prior to the events of the franchise. Hämsterviel has shown signs of his own high levels of intelligence, including having managed to escape from prison on his own, constructing a plasma blaster using only the items from an Earth-based hamster cage, as well as the fact that he secretly modified his prison cell to be his laboratory.

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 the family's new "dog", Stitch, also proves to be less than favorable (upon meeting him, Stitch promptly throws a dictionary at Cobra Bubbles' head). He is voiced in the films by Ving Rhames, in Lilo & Stitch: The Series by Gantu's voice actor Kevin Michael Richardson, and in Stitch & Ai by Richard Epcar (who is not credited in the role). [ citation needed] 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.Hypnotism through a siren song that affects the morality of listeners (primarily experiments made before her)
