7. Donkey Kong
It’s on like the video game gorilla in question! Before Bowser and Wario, Mario’s main adversary was a girlfriend-napping ape named Donkey Kong, tossing his trademark barrels around to thwart the heroic carpenter (Mario’s initial career path in 1981). And here’s a fun fact for you: Donkey Kong was almost a game featuring the characters from Popeye, with the titular primate having been modeled after Bluto.
