Comet, A.K.A. Experiment 503, is an illegal genetic experiment created by Jumba Jookiba. He is designed to create meteor showers. His one true place is putting on fireworks displays.
Experiment 503 was the 503rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to create meteor showers (does so by flying around planets at top speeds and firing balls of fire that cause mass panic).
503 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.
All of the experiment pods were released and scattered across the island of Kauai.
At the unknown point, he was activated, captured, tamed and named Comet.
He glows very brightly.
- Comet's pod color is green.
