Punch-Out!! is a lively boxing video game where you play as Little Mac, train to be champion, and share quick thinking and fun at home.

You usually play as Little Mac, a small but brave boxer who wants to become the W.V.B.A. champion. The series started in arcades and later moved to home consoles so families could play at home.
You use left and right punches like jabs and hooks, plus dodging and blocking. Timing matters—if you press the right punch at the right time you can land big hits.
It introduced Little Mac and his trainer Doc Louis.
It's a short WiiWare bonus game released in 2009 that acts as a friendly prequel where Little Mac spars with Doc Louis. It was given to Club Nintendo members for a limited time.
For example, the SNES game Super Punch-Out!! was included as extra content in the GameCube version of Fight Night Round 2, and you could unlock Little Mac there.
Captain N: The Game Master featured King Hippo as a main enemy.
