Motormouth has an enormous engine, and an ego to match. While his vehicle mode would be useful for transporting materials, he rarely uses it for this purpose, because that might scuff his paint. He often finds himself distracted by the sight of his own reflection, although it's not entirely clear whether this is due to the considerable pride he has in his appearance, or just his extremely low intelligence level. Constructed with minimal brain circuitry, Motormouth is fortunate to possess super-fast speed that lets him tear up the streets to elude the Decepticons. Although in truth he'd like to tear them up, too.
