My Slurpuff, the same one who took down Solaris' Garchomp Single handedly, has taken down the glitched Mega Rayquaza single handedly. Eat that Fairy type haters.
It is only in the original release of 14.5, but it has been patched. It was stray test code. ((probably to check if the code for Mega Ray was working. SInce they want to have the complete code that would be in a pokemon game in Reborn even if it isn;t used.))
