Hun-Gurrr is the leader of the Terrorcons and would be quite the model Decepticon and military strategist if he could just stop stuffing his two mouths. Hun-Gurrr is a terrible glutton, constantly filling his stomach with as much energy and materials as he can find. He only ever stops his insatiable feeding frenzies to fulfill his other desire: wanton destruction. In this capacity he is quite adept as a military leader, although his underlings are sometimes unable to understand his commands when Hun-Gurrr has stuffed his face(s) full of fallen Autobots.
Hun-Gurrr can combine with the other Terrorcons to form Abominus. His name is also spelled Hun-Grr, Hun-Garr, Hun-Grrr, and Hun-Gar.
His alt-mode is a Two-Headed Dragon.
