Angel, A.K.A. Experiment 624, is an illegal genetic experiment and the 624th genetic experiment created by Jumba Jookiba with Hämsterviel's funding. She is designed to revert rehabilitated people and experiments to evil with a siren song. She was captured by Gantu, but was rescued in "Snafu". Her one true place is with Lilo and Stitch as a pet, famous pop star and singer. She is Stitch's love interest.
- Being that she's voiced by Tara Strong, voice clips of Bubbles and Twilight Sparkle (mainly the latter) are used for her for giggling, laughing and certain lines she speaks.
