A hero who fights anyone, anything, anytime, anyplace, anywhere and anyhow.
Like Mystery Science Theater 3000, A Random Hero has no control over when things start and end.

Usually battling a motley crew of baddies, Nothing is never normal.

Also, A Random Hero is the savior people dont count on being saved by.
Guy: You saved me...Who are you?
RH: Im Random Hero!
Guy:...I wanted Superman.

A.K.A Ryan Dunn. A man in his late 20's willing to jump in vats of shit and or fish for the amusement of other. Is also willing to insert small toys into certain parts of his body for fun.
The Random Hero can also be likened to a garden gnome (albeit a cute one)

A guy who decides to be awesome when the right time comes. Members of the legion of Randomhero are the real past, present, and future.

Also, Randomhero's tend to be naturally gifted gamers.
Dude: That man is a champion
Other Dude: Naw man, he's a Randomhero.

Dude: He got the game yesterday, and he's already better than me, and I've had it for years
Other Dude: He's a Randomhero, what did you expect?
