Bumper is a fictional Autobot character associated with the Transformers franchise, most notably appearing in early toy and comic continuity rather than as a major on-screen cast member. He is typically portrayed as a small, agile robot who transforms into a compact vehicle, emphasizing speed, reconnaissance, and quick movement over heavy combat. In stories where he appears, he functions as a support or background Autobot, helping the team with scouting and mobility. He is not usually a central protagonist, but a recognizable minor character for collectors and longtime fans.
