Experiment 100 was the 100th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to be a pickpocket (does so by performing magic tricks and using hand eye to steal money and other expensive items).
100 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 an unknown point, 100 was activated, captured, tamed, and named Trickster.
