>>5322510>>5322518Bruticus is dumb in the sense that he has no creative thought or initiative. He can follow orders, but he can't improvise or strategize.
And that's really a common enough theme among the gestalts. Superion has the same issue, actually.
And besides, none of them are as rock stupid as Abominus. Trivia: He has a tech spec Intelligence stat of 1. No other transformer in the 30 years of the franchise has ever had a 1. Not even the non-sentient drones. Abominus is THAT dumb.
