Other appearances: This character would become Gigastorm. There have not been any other characters with the name Megastorm. However, this mold was used to make G2 Megatron.

Transforms into a tank, in which form his attacks have the highest class of destructive force of any in the story. However, the trouble is he takes too long before he fires. His brother Galvatron is more idealistic and fastidious...while Megastorm has that much more of a realistic atmosphere than his elder sibling about him. Having learned of the "Lord of Angolmois," the fearsome secret of the planet that is the stage for their battles, his brother has become cautious, which has led Megastorm to be disloyal and mistrustful at times.
