Berserker (F-Zero)

Berserker ​is a cloaked man who pilots the Red Bull. In reality, he's Bart Lemming, the former Captain Falcon who assumed another identity to infiltrate the Dark Millions association. He faked his death in an accident with Blood Falcon and began working for Don Genie in the illegal, underground races he sponsors. He later reveals himself to Rick Wheeler in the final showdown with Black Shadow.
