He also dug up unused mega-evolution for Latias and Latios.
Pokemon X and Y has been out for a few weeks now, and if you thought you had “caught them all” you may want to think again. A hacker that goes by the name Smealum has been searching through the Pokemon X and Y source code and has discovered three, currently unobtainable, legendary Pokemon, as well as unused mega-evolutions for generation III legendaries Latios and Latias.
This is obviously a massive spoiler for those of you who would rather wait for Nintendo to officially reveal them, so i’m going to throw a spoiler tag around the gallery.
