Ace, also known as Experiment 262, is an illegal genetic experiment created by Jumba Jookiba and a character in the Lilo & Stitch franchise. He is a failed experiment that has no evil uses and is pure good with a hero complex; this was caused by Jumba mixing his formulas inaccurately. His one true place is as a member of AARRGGH (Association of Alien Rejects, Reformed Geniuses, and Girls from Hawaii), balancing out Jumba's evil, and as a local do-gooder.
