I'm probably super late to the boat but as everyone knows, the YMX that we see playing chess with Eraqus has silver/grey eyes and rounded ears while Time Traveling YMX has the typical Nort features (yellow eyes\pointed ears). What bothers me is that we were led to believe that Time Traveling YMX was the youngest version of himself but it's clearly obvious that the Xehanort we see playing chess with Eraqus is even younger!
Personally I think that MX tainted himself with so much darkness that he became an entirely different person. So much so that when as Ansem he went back in time, he was only able to reach those versions of himself that had already been tainted by darkness; he wouldn't have been able to retrieve/reach Chess YMX because his heart is so vastly different it wouldn't count as a version of himself anymore. Of course that would leave the question of why YMX would return to Destiny Islands when he had already left them. Thoughts? Opinions?
