Protopet

Protopets were Megacorp's genetically-modified pet. Designed as the ultimate plaything, the pet was released with defects (purposely left unchecked by Captain Qwark, who was masquerading as Abercrombie Fizzwidget [the CEO of the company that made the pets]). He intended to create a galactic crisis in which these "cute" furballs would wreak havoc across the galaxy so that he could step in and "save" the galaxy from destruction, reestablishing his superhero title following his defeat by Ratchet and Clank during the events of the original Ratchet & Clank.

The Protopet, dubbed "Experiment #13" during its testing stages, was stolen by the thief prior to its intended release, so "Fizzwidget" hired Ratchet and Clank to recover the creature. They eventually did so, not realizing the conspiracy at hand. The pets were soon released to the public despite warnings from Megacorp's scientists, most of whom were devoured by the original Protopet during testing. It became clear that the Protopets' sole intention was to consume other sentient life, be it organic or even robotic.

The released pets began to attack people all over the Bogon Galaxy, causing chaos across numerous worlds in the galaxy. They reproduced by opening their mouths and spawning 3 more, and there were easily 50 on one screen all at once. Several planets, among them Grelbin and Damosel, were quickly infested by the Protopets, threatening social order and prompting the intervention of local authorities. The Protopets were ultimately defeated when former Megacorp employee Angela Cross used the Helix-O-Morph to render them all docile.

It is unknown how their rampage across the galaxy affected the sales of the Protopets when they became tamed.
