Reuben is known as Experiment 625; the experiment created by Jumba right before Stitch (626) was created. He has all of his abilities (he is bulletproof, fireproof, unbelievably intelligent, has night vision) and he even can speak more fluently in English and other languages than Stitch. Though he decides to be more laid back then use his abilities and to make sandwiches. His best friend, Gantu, used to be the villain of the story, but he was redeemed along side Reuben. Reuben has a Brooklyn accent and a sassy wit, but underneath his sarcasm, he is compassionate.
