Demotifier, A.K.A. Experiment 374, is an illegal genetic experiment created by Jumba Jookiba. He is designed to make new things rust quickly to make it look old.
Experiment 374 was the 374th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to make new things rust quickly to make it look old.
374 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 Demotifier.
