Doc Louis
Jerome “Doc” Louis is an ex-heavyweight boxing champion and Little Mac’s coach in the Nintendo game series Punch-Out!!!. He is also an infamous YouTube Poop meme using a clip of him training Little Mac on a bike and making it look like he is stealing Mac’s bike.
King Hippo
In Mike Tyson’s Punch-Out!!, King Hippo is a boxer from Hippo Island. Both his girth and face resemble a hippopotamus. He has helpfully taped an X over his belly, which gives Mac a target to aim for when trying to hit King Hippo’s weak spot.
Little Mac
In the Nintendo series Punch-Out!!, Little Mac is a scrappy underdog boxer who’s trained with Doc Louis. He’s worked his way up from the bottom to face Mike Tyson, Mr. Dream, and even make an appearance in the next Super Smash Bros.
