This is a crossover superstory. Basically, suggest shows/games/comics/whatever this website will allow, and I'll pick 2 (or more if I feel like it) and make a crossover, with all of the stories combining into one ending. For now, the beginning.
Have you ever wondered how your favorite shows would interact? How two movies would combine? This is what the omniverse makes possible. Then there is one world where they all meet. This world was named "Fanfiction", after what unified the worlds in which they lived. Friends, foes, and everything inbetween arrived. A true paradise was born. Although they still needed to reside mostly where they came from, they spent their spare time in Fanfiction, occasionally even visiting other worlds. Thus, the crossover had been born. However, there is one who does not like Fanfiction. His plan is unfolding, and it is up to the characters to stop his plans. It is, however, up to the fans to decide who is capable of this task. Time runs short, so we must act soon.
Leave suggestions on series and characters in the review box. Seriously, I don't know what you want if you don't tell me.
