Protopet

Protopets are Megacorp's genetically modified pet. Designed as the ultimate plaything, the pet was released with defects by Captain Qwark, who was masquerading as Abercrombie Fizzwidget. The released pets began to attack people all over the Bogon Galaxy, causing chaos.

The Mutant
Qwark's plan was to have saved Bogon from the pets he unleashed and appear as a hero in the eyes of the citizens. However, due to an accident with Angela Cross's Helix-o-Morph, the original pet became a ravenous mutant and had to be neutralised by Ratchet, who returned the pets to a docile state.
