Angel, A.K.A. Experiment 624, is an illegal genetic experiment created by Jumba Jookiba. She is Stitch's love interest, mate (or "boojiboo" as they call each other), and female counterpart. From Stitch! onward, she is also considered to be a major character in the Lilo & Stitch franchise. She is designed to turn people and experiments from good to evil. Programmed with a special musical neuro-linguistic behavioral modification trigger, she sings a siren song to turn her victims evil. The effects can be reversed by chanting the evil song backwards. She was found by Gantu, who used her against Lilo and Stitch until she turned on him, leading him to capture her in retaliation. She was later rescued in "Snafu". After her rescue, she became an intergalactic singing sensation and Stitch's truelove. Her demanding career requires her and Stitch to maintain a long-distance relationship.
