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.
