Experiment 005 was the 5th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to move Jumba's heavy equipment.
005 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, 005 was activated, captured, tamed and named Truxx.
Truxx is a red and black remote-controlled off-road vehicle/box-like experiment with four legs and a Cannonball (520)-like head with a blue nose, short ears, four fangs (two from the upper jaw and two from the lower jaw) and a thick, small tail.
He is designed to move heavy equipment.
