That old book idea turned to fan-fiction

I still have some plans, instead of going through the universes of video games, why not go farther? The last universe  will be at midgard, or earth in the marvel universe. A final battle of the possessed creature against the mightiest hero's of all games and the marvel's universe. A creature took the strongest sources of power in those universes and has almost enough power to be unstoppable. Will sonic, master chief, kirby, kratos, mario, link, mega-man, spyro, Mewtwo, naruto, godzilla, the Avengers, the Fantastic 4, the X-men, and anyone else who can fight stop mephiles, free the innocent creature trapped, and save their universes. And because this is a fan-fiction i dont need the rights to use the characters :3 the pic is just a hint of what one out of 5 hidden universes will be in as well
