El Carbon, A.K.A. Experiment 596, is an illegal genetic experiment created by Jumba Jookiba. He is designed to release carbon monoxide to poison the air.
Experiment 596 was the 596th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to release carbon monoxide to poison the air.
596 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 El Carbon.
