Fan Casting The Smash Games: Chapter I

Heroes from all across the multiverse are bought together in the middle of a strange, void-like realm known as "The Final Destination" where they are forced to fight each other in a constantly-morphing world at the (literal) hand of an entity known as Master Hand, who has teamed up with the heroes deadliest villains. Peace soon breaks out among the fighters, but they have to find a way to defeat the villains, stop Master Hand, and save their worlds before they are all merged together by the villains.
