This BS though, in game, there's all this dialogue of Pokemon only mega evolving when a strong bond with Pokemon is achieved, but really we can just strap on the bracelet and evolve anything freshly caught
I agree. They should have limited to pokes that the player has high friendship/affection.
I don't think Satoshi-Gekkouga takes on Satoshi's appearance at all. In the episode we get to know about the mythical gekkouga, they show a picture of it and it looks the same as Satoshi-Gekkouga so I guess Synchro evolution wont make your poke look a little bit like you.
