Intro. You were just now doing your everyday activities whatever they may be, and suddenly you were transported to a massive arena, and all around you are hundreds of different types of people and things of all kinds of races and most are things you've never even seen, some are things you'd only seen in fiction. There are people who look human but have elements surrounding them, some or bipedal animals, some are bipedal insects, some are even aliens of all types, people of all shapes and sizes all look around confused until a massive booming voice booms out of big speakers "HELLO EVERYBODY AND WELCOME TO THE FIRST EVER TOURNAMENT OF WORLDS, PUT YOUR HANDS TOGETHER FOR OUR VERY FIRST RANDOMLY SELECTED FIGHTERS FROM ALL OF YOUR UNIVERSES, We have some from alternate universes, some from completely different universes, it will surely be a GRAND tournament so sit back get a drink and wait for the very first round to start.

The Tournament of Worlds
