Galvatron is a powerful Decepticon leader in the Transformers franchise, often portrayed as a transformed and upgraded form of Megatron rather than a separate ordinary individual. He is a major antagonist in multiple series, especially in Transformers: The Movie and later continuities, where he serves as a ruthless, unstable warlord obsessed with conquest and destruction. His role is typically that of a terrifying enemy who commands Decepticon forces and threatens both Autobots and entire worlds with overwhelming firepower and ambition.
