He is still the same guy, but he had grown out of some old habits of his. first of all, he was tired of wearing red shoes, so he got some new purple ones so that he could be original/unique (also his old shoes were kinda worn). Second of all, he sharpened his teeth and made himself more intimidating and threatening. (btw, he still calls himself 2012 X and claims to be 2011Sonic's most beloved creation of all (self proclaimed))
