Hmm I would have to say either Light Yagami or Lelouch since both of them ( to some extent) were able to hold the world in the palm of their hands with just their minds. (and the help of magic of course.)
Omg you have to find it >.< it's so much fun. I am trying to find my copy of Fable 2 but its not wanting to be found. Same with all my xenosaga games haha
