The "civil war" between the avengers has just ended, Hulk and Thor are still no where to be found, Captain America and his side have become vigilante's and haven't been seen for months.
Just when it seemed like the world had finally put their superheroes under control, hundreds of more have shown up, some more ruthless than anything seen before.
Along with the new heroes, more villains have appeared as well, some of which threaten the very existence of the planet earth.
