"I am Bad Wolf"
As those words were spoken, all of the alternate universes were re-written. Except for 2 that would later play a role in 3 people's lives. In one universe, Doctor Who was a show. In another Artemis Fowl lived peacefully with the fairy folk. One universe had only a time travelling duo in a Delorean. Another had Dark Helmet and Lonestar. Another was a vampire and a werewolf fighting over the girl they both loved. In one, the world was called Lore, and had heroes of tremendous power. One was where all the superheroes were real. Another with only cats which spoke of a great prophecy. One where all cartoons came to life. The last was the most horrible of all, with planet fusion trying to take over the world.
I am The Watcher, and these are the chronicles of those dimensions.
Authors note: Please don't kill me. I'm still working on this and others. This one came into being when I was in bed wondering what would have happened when Rose said those words. Side note: I don't own the things I'm talking about.
2nd side note: The Watcher is a character from marvel comics that watches over the dimensions studying the different possibilities that the dimensions hold. He watches over us. Kind of like The Doctor.
