A ruthless businessman and industrialist, Grax was willing to do whatever it took to solidify his place at the top of Nebulan business world. Not that he needed much convincing to undergo the binary bonding process to combine with Skullcruncher in order to eliminate his business rivals, the Decepticon methods of utterly and cruelly absorbing all foes were just more literally bloody versions of Grax's own. Skullcruncher didn't see the similarity though, Nebulan corporate types were barely even a snack...
Grax adds considerably to the somewhat slow mind of Skullcruncher, which admittedly isn't hard, but still finds most of his suggestions ignored unless they involve A) eating the corpses of your enemies B) inventive noises to make when grinding your teeth.

- Voice actor:
- Skullcruncher with Grax (Headmaster, 1987)
- Grax transforms from an armored humanoid into a robot head. Though he only came with his partner Skullcruncher, in head mode he is compatible with any other Headmaster body. On the larger Headmasters, he gives three of Skullcruncher's Tech Spec stats in their display window, but the smaller ones still display their normal heads' stats due to their construction.
