10 Best Super Mario Fan Theories That Explain Everything

There are some fan-theories about Super Mario that make too much sense to dismiss.


Super Mario is the most celebrated video game franchise of all time. Despite its legacy, the premise is very simple; an Italian plumber living in the Mushroom Kingdom must rescue Princess Peach from the Koopa King, Bowser. That is the entire plot to about 80% of the mainstream Mario games.

Because the characters and plot are so basic, very little is known about the Mario universe. This has caused many gamers to try and fill in the blanks with their own theories. Like most speculation, a lot of these fan-theories simply don't stick and thus, are dismissed.

But there are handful of fan-theories that make too much sense to be discarded. Even if they're not true, some of these ideas should be explored.

Who was King Boo when he was alive? Why does Mario act completely different in his debut game? How does Nintendo's moustachioed mascot have time to have hundreds of adventures? And most importantly, what does a Shy Guy look like? (Okay, that one isn't important, but it's definitely the one that keeps me up at night.)

Here are some Super Mario fan-theories that explain everything.
