Diesel, A.K.A. Experiment 448, is an illegal genetic experiment created by Jumba Jookiba. He is designed to spill diesel fuel.
Experiment 448 was the 448th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to spill diesel fuel.
448 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 Diesel.
