The Worlds of Trophies; home to many people and creatures of many types. These worlds all share one name in common: Earth. To categorize them, they each have been given unique subnames; such as Nintendo, Sony, Capcom, Sega, Ubisoft, Microsoft, Activision, EA, Namco, Valve, and many MANY more. All of these Earths were ruled by 2 deity figures; the Hands of reality: Master Hand, the Creator, and Crazy Hand, the Destroyer. With their powers they have constructed a fortress in the shape on a flat stadium, travelling through Hyperspace at speeds breaking light's record altogether. However one day, an enigmatic figure known only as 'G-Man' overpowered the hands to carry out a task. G-Man was the perfect subject for world domination, as he was not known to be truly on the opposite side of justice. The plan was simple; assemble a legion of brutes and fiends, who have all had trouble with a hero or two in the past, and trophify anyone worthy enough to be called 'Hero'. G-Man began to carry out this dark deed with other villians like Bowser, Dr. Eggman, Albert Wesker, Razorbeard, Dr. Wily, Ganondorf, King Dedede, Ripto and Dr. Neo Cortex.
Little did G-Man knew that he was not the one pulling the strings in this dastardly operation, as a 3rd deity made its way to the platform; Polygon Man. After a great battle, the crystalline head had overpowered Crazy Hand. Taking control of the fallen hand to become his own, Polygon Man and Crazy Hand easily defeated Master Hand. Both hands in his possession, Polygon Man began toying with each Earth; one by one they joined together with each other, their inhabitants not feeling any changes whatsoever. Once the deed was done, Polygon Man contacted Tabuu, the ruler of Subspace, who having been revived from his last defeat in Super Smash Bros. Brawl, now wants revenge on the entire multiverse. It's up to Mario, Sonic, Snake, Mega Man, Pac-Man, Crash, Rayman, Banjo, Chris, Link, Kirby, Spyro, Sackboy, Gorden Freeman, Heavy, Niko, Big Daddy, Master Chief and all the other heroes and villians to defeat Tabuu and Polygon Man and save not just The Worlds of Trophies, but the entire gaming universe.
