Naomi, A.K.A. Experiment 631, is an illegal genetic experiment created by Jumba Jookiba, and Joshua Sinclair's love interest.
She looks like a green version of Angel (624), except she is half way between Stitch and 627's heights. She has expendable appendages, which include a set of extra arms, Angel-like antennae and three spikes on her back. She also has a sky blue and black Thai-Chi symbol on her chest. Has all powers of 626, such as super computer thinking, indestructibility, etc. Unlike Stitch, she can lift 4,500 times her own weight, she is an excellent swimmer, and she is a black belt in all known forms of martial arts on multiple worlds. Also, Jumba designed her to be immune to 627's powers.
