Mudflap is a fictional Autobot character in the Transformers film series, introduced in Transformers: Revenge of the Fallen. He is a smaller, fast-talking robot who often acts as comic relief alongside his twin brother Skids. Mudflap helps the Autobots in their battles against the Decepticons and participates in key action sequences during the human-alien conflict. His personality is impulsive and playful, and he serves mainly as a supporting character rather than a central hero.
