Living underneath a MegaCorp outpost in a large cavern, this creature was the Mother Beast known to lay the eggs that hatched the Mutant Swamp Beasts. Before Ratchet confronted and defeated it, apparently nobody had seen this mysterious creature and lived; however, Qwark had apparently had a run in with one after his arrival in the Bogon Galaxy and been eaten alive by it. Qwark survived this encounter and escaped, going on to masquerade as Abercrombie Fizzwidget. Upon regaining his memory aboard the Starship Phoenix in Up Your Arsenal, Qwark recalled being eaten alive by the monster.
