Hun-Grrr likes to think of himself as being a gentlebot and Renaissance mech. To that end, he likes to research and read in-depth about the planets that the current Autobot-Decepticon war takes him to, especially regards the beautiful vistas the world in question possessed before the fighting destroyed them. His altmode—a Algean Two-Headed Razor Beast—was even taken from one such planet where the beasts are regarded with nobility by the populace. He combines with the other Terrorcons to form Abominus.
