To put it mildly, one could say that Hardhead's cranium isn’t exactly crammed with cerebral circuitry. Or one could say that he’s as dumb as a rock. And not one of those cool geodes, either. I mean a big, grey piece of slag. Hardhead has a tough time even staying on task long enough to finish a sentence, let alone coordinate a tactical nuclear strike. He can be easily fooled and needs to be constantly reminded of exactly what he’s supposed to be doing. He can't even pronounce his beast mode's name—although, to be fair, he's not alone there.
