From John Margiotta's Personal Collection, this Dark Age Abomination is presented on display.
 
Originally bred to be a further evolution of the Sawblade type, Mandible actually was an aberration of selective principles.
With changes to many of the subdermal armor pieces into an exoskeleton and sporting two weapon arms instead of one, each bigger in size than that of the original creature, Mandible proved to be even more deadly in open conflict.

Unfortunately Mandible was totally unable to care for itself and as with nearly all aberrations, the nursing drones left it to starve to death by the hatching drones or to fall prey to the stronger beings with better survival chances. But it defied all expectations by simply surviving.
