Scourge

Scourge is Galvatron's implacable tracker and leader of his own cadré of huntsmen, the deadly Sweeps. He was created by Unicron from the remains of a near dead Insecticon. Immensely powerful like all the Unicronian Decepticons, arrogance is his only true weakness. Despite being quite powerful in his own right, Scourge generally acts as a near subordinate to Cyclonus and, despite his leadership of the Sweeps, is generally content to take orders from others. Scourge tends to grumble and complain a bit (a habit sometimes shared by his Sweeps).

But then again, you'd also complain if your boss spent so much time beating you up, wouldn't you?
