Hmm... Me thinks possible mascot for Ouya. On a side note, if you need a reference for 2-player then Punch-Out!! (Wii) or Telero Boxer (Virtual Boy) would be a good start.

I demand a sequel to this, a prequal to this, and a DLC pack that makes you fight Rosie O' Donnell. If... you know... her fat ass would fit in the arena.
