Dupe (Lilo & Stitch)

Experiment 344, nicknamed Dupe, is a genetic experiment created by Dr. Jumba Jookiba. This little Lemur-like creature has the unique ability to clone anything it sees by using its antenna. However, it has a drastic effect on other experiments like 626 (Stitch): it may increase their numbers, but it weakens them and their ablilities diminish.
