If that's the case, does Heatran turn into Volcanion? And Shuppet into Hoppa?
Hmm... good question. I assume the relation with Carbink is Diancie's gimmick, like Manaphy with Phione. Volcanion and Hoopa does not have too many similarities with Heatran and Shuppet, respectively. I do wonder if Volcanion is the mysterious pokemon that caused the Lumiose black out. I remember some NPC mentioning a lava pokemon. Hopefully Volcanion can be found in the power plant because there are 3 unlocked doors and not knowing their purpose is annoying the hell out of me.
