The Dictator

The Dictator (also Vast Creator, Infinity Lord, Author, Asshat) is a fully omnipotent extrauniversal version of Alex, and is capable of manipulating the plot to his will. He has created and destroyed infinite universes within infinite time, but the Enderverse remained a constant. Creator Alex, his avatar within the Enderverse, has some of the omnipotent abilities, but more sensibility due to being thrust directly into the situations of the Vast Creator's perception. 
Everything seen within his mind becomes completely canonical to the already confusing Legend of Ender timeline.
