Confident, clever and sort of effeminate, Starscream is Galvatron's second-in-command in all but name, something that drives the actual second-in-command, Megastorm, up the wall. Easily the most reliable Predacon on Gaia, Starscream is usually perfectly content with his position within the ranks, but he’s not above betraying his comrades if the situation calls for it. Starscream is something of a snob and a narcissist who doesn't suffer fools or low-class fashion rejects lightly.
