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 of endearment 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.[33] She was designed by Jose Zelaya, an El Salvador-born character designer working at Disney Television Animation.[31]
In her eponymous debut episode, "Angel", she was introduced as a saboteur working for Gantu and Hämsterviel, having been found by the former prior to the episode's events. She causes Stitch to fall in love with her at first sight in order to trick him into bringing her into the Pelekais' home and using Jumba's computer to find rehabilitated experiments. However, she develops feelings for Stitch due to his kindness towards her and betrays Gantu to prevent him from bringing experiments to Hämsterviel, although he responds by capturing her and taking her away from Stitch. In her only other episode in The Series, "Snafu", which first aired just before finale film Leroy & Stitch premiered, Lilo and Stitch rescue Angel along with several other captured experiments in Gantu's spaceship, and she and Stitch begin dating as a couple.
Angel becomes a much more recurring character in the Stitch! anime series, having become a successful intergalactic pop singer since the events of Leroy & Stitch. She maintains a long-distance relationship with Stitch in the anime, visiting him during breaks in her extensive touring.[34]
