First Game Appearance: Twisted Metal
Sweet Tooth is the demented, smiling clown that adorns the cover of every Twisted Metal title and, because of the franchise's immense popularity, he ended up becoming a face for Sony's early video game efforts as well. Consider this: when people think vehicular combat, they think of an ice cream truck piloted by a clown. How messed up is that? It really gives us chills just thinking about it. Inhabiting our nightmares is certainly one way to become an effective mascot.
