Sparky, also known as Experiment 221, is an illegal genetic experiment created by Jumba Jookiba and a character in the Lilo & Stitch franchise. He is the first experiment to be activated and rehabilitated, and first appeared in Stitch! The Movie. He is designed to create crippling electric surges. His one true place is powering Kilauea Lighthouse, which had been previously abandoned for years due to requiring too much electricity.
