Experiment 624, Angel is an illegal genetic creation of Dr. Jumba Jookiba. She resembles a small, pink koala-like creature with feminine features including longer eyelashes, large dark purple eyes, rounded ears without notches, a smaller purple nose, two long tendril-like antennae, and a subtly puffed-out chest. Slightly shorter than Stitch (Experiment 626), she was engineered with a specialized siren song that contains a neuro-linguistic trigger capable of reverting rehabilitated experiments and individuals to their original evil programming. The effects reverse when the melody is sung backward, and Stitch possesses immunity due to his later creation. Activated on Earth, Angel was captured by Captain Gantu and feigned affection for Stitch as part of a trap. However, guilt over betraying him led her to rescue Stitch and later join the reformed experiments, developing a romantic relationship with him. Years later, she became an intergalactic singing sensation with a more self-centered demeanor. Her relationship with Stitch endured despite periodic fickleness, including brief infatuations with Experiment 627, a confidence-boosted Reuben, and Kijimunaa, all of which ended when their flaws emerged. Angel aided Stitch in critical missions, fought against the Leroy clones using martial arts, and appeared under Hämsterviel’s control. Stitch’s fear of her anger surpassed even his fear of water. She also made a brief appearance in the 2025 live-action Lilo & Stitch film.
