Video Game: Mike Tyson's Punch-Out!! (1987)

Standing only 3'10" and weighing in at a scant 90lbs, Little Mac should have no business stepping into a boxing ring. But Little Mac has the one thing that sports movies have told us is all a hero needs: a big old heart.

While other fighters had skills and the ability to be Mike Tyson, all Little Mac has is some rudimentary boxing skills-he needs to jump a lot of the time to hit anything-but he can jab and body blow his way to the top. And if Little Mac beat Iron Mike at the end of the game-and this wasn't a guarantee, mind you-then Little Mac accomplished one of the toughest feats in sports video game history and that's why he belongs on this list.
