Experiment 625, now known as Reuben, is an illegal genetic experiment created by Jumba Jookiba, and former villain from the Lilo & Stitch franchise. He serves as an antagonist for The Series, but later becomes a protagonist in Leroy & Stitch. He is designed to be abnormally strong, virtually indestructible, super intelligent and very mischievous...in other words, he is a prototype of Stitch, even equipped with more lingual skills. The main flaw in his design was laziness; the most strenuous thing he did was make sandwiches, albeit delicious ones. Before the events of Leroy & Stitch, Reuben didn't do much besides make sandwiches all the time, much to Gantu's anger. His one true place is with Gantu as his galley officer. He is voiced by Rob Paulsen.
