Motto: “Ashes and ruins are all I leave in my wake.”

Function: Grand Duke of Destruction

First Television Appearance: “Megastorm Reborn.”

Profile: After being dropped into a pit of raw Angromois energy by the treacherous Starscream and BB, Megastorm was reborn into the mighty Gigastorm. With his newfound power he commands his troops more ferociously than ever before and openly argues with his brother, Galvatron.

Abilities: Gigastorm is a massive upgrade from his original form. In dinosaur mode Gigastorm can use an energy ray to increase his size to monumental proportions. The “Gigahorn” on his head is harder than diamond and can pierce through all matter of substances. In battle station mode, Gigastorm can become a massive piece of artillery with enough firepower to level a city in an instant. In Fortress mode Gigastorm is an all-powerful base that can move over all forms of terrain and fly if need be.

Weaknesses: Gigastorm’s more defiant nature has placed him on his brother’s bad side more so than before. On top of that Galvatron controllers the energy ray which dictates his size.
