The Quintesson Executioner is a mantis-like, roughly anthropoid creature. He is distinguished by nonprehensile claws and large splayed feet. The Executioner’s evil presence is propagated by his seething red eyes and a forked goatee (if the Executioner had fingers he would habitually stroke the goatee whenever he hatched an evil plan). In Transformers: The Movie, the Executor was charged with the task of throwing the lever and sending unfortunate courtroom defendants into the churning Sharkticon pit.

Having created Autobots and Decepticons as servitor races, the Quintessons were defeated by their creations, expelled from Cybertron, and forced to colonize the much less grandiose planet of Quintessa. Consequently the Quintessons are now disgruntled, and are forced to entertain themselves with mock trials, petty cruelties, bizarre experimentations and attempted subterfuges.
