The universe is caving in on itself. Rips are appearing all over the universe where they shouldn't. Good and Evil versions of your favorite characters are appearing out of nowhere. Some simply don't care what happens and will be friendly, while others are bent on destroying the original version and replacing them. If that wasn't bad enough, the universe only has one year left to survive if they doppelgangers aren't destroyed or sent back to the original universe they came from. Looks like it is a game of cat and mouse. . . and nobody is playing fair.
