Experiment 433 was the 433rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to be an improved version of 010.
433 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 Speck.
Speck is a dark purple Felix (010)-like experiment.
