Leroy, A.K.A. Experiment 629, is an illegal genetic experiment and the last known experiment to be created by Jumba Jookiba. He appears as the titular secondary antagonist of Disney's 2006 television film Leroy & Stitch. Hämsterviel forced Jumba to create Leroy and design him as an improved version of Stitch with extra destructive capabilities and less fluffy. Thus, Hämsterviel could use Leroy to take control of the Galactic Federation and finally capture all of the other experiments. Leroy is an unstoppable monster. His one true place is in prison.
