The Multiversal Traveller

The multiverse is the theory that there exists an infinite number of universes, where each and ever possible outcome of every decision ever made is played out. These universes may be incredibly similar to our own, or completely different. According to the theory, everything that can exist, does exist somewhere in the multiverse.

And what will someone do when they discover the truth of the multiverse, and how to traverse its many branches? Use it for debauchery and depravity, of course. First of all though...

Who is our intrepid explorer?
