Gameover, A.K.A. Experiment 428, is an illegal genetic experiment created by Jumba Jookiba. He is designed to restart games all the way back in the beginning and he also breaks their video game system.


Experiment 428 was the 428th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to restart games all the way back in the beginning.

428 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 Gameover.
