The End of the Universe
"Two wizards, a witch, a Timelord, a Bad Wolf, a detective, a girl with long magic hair and a guardian will come together in the most unlikely of events."
And it is most certainly the most unlikely of events. All universes collide. The past, the present, the future. Parallel Universes. Legends, Fairytales, and Myths. They all collide. Harry Potter, Ron Weasley, Hermione Granger, the Doctor, Rose Tyler, Adrian Monk, Rapunzel and Jack Frost must team up to fight against the newly formed evil. Because, all the evil in every world has joined together too, and they will stop at nothing, to keep all universes bound together. And that is why they have to stop them, and set all universes back in their rightful places. For if all universes stay bound together for too long, all universes will cease to exist. Everything will be gone.
"The fabric of Time will be torn. The Universe will crack. The End of the Universe. The end of Time and Space itself. There will be nothing...if they fail."
This is a Harry Potter, Doctor Who, Monk, Rise of the Guardians, Tangled Crossover.
