Megastorm

Megastorm is the Duke of Destruction and Galvatron's younger brother. He puts on a tough-guy facade before his troops but quickly calms down around his older brother. Megastorm secretly wants to be stronger than Galvatron, while viewing Galvatron's schemes as too risky and frightening, and repeatedly plots to usurp him as Emperor. Galvatron knows about the attempted treachery but looks the other way out of brotherly love.
