A rather odd-looking individual wearing a suit, top hat, red bow tie and sunglasses. He asks the player if they want to try their luck in the Battle Arena for a chance to win big money. If the player agrees, they will enter a crowded fighting arena where they will fight three bosses in succession: Simondo Belmont, Psycho Mother and Huge Face. If they succeed in defeating all three, a secret ending will take place where the heroes are sucked into an inter-dimensional portal and are sent back in time to a prehistoric age, where they become leaders of a tribe of apes.
If the player does not accept the Mysterious Character's deal, they will simply return back to the room below.
