Experiment 221 (a.k.a: Sparky) is an alien experiment created by Dr. Jumba Jookiba. He is the first experiment Lilo and Stitch caught and rehabilitated. Experiment 221's primary function is to create crippling power surges, as well as possessing other electrical abilities.
Experiment 221 resembles a yellow Chinese dragon with skinny arms, legs, and small body, a slightly twisted yet pointed tail, a large oval-shaped head with a wide mouth, a round nose, dark blue eyes and long antennae.
