Uggggh, not this again! No! >:( Bad! *gets out spray bottle* I don't want anymore stupid fights between our group on this site! The only reason I've been objecting to the mega evolution of two Pokemon at once is because it doesn't follow anything in the logic already set up by both the game AND the anime. Other Pokemon, regardless of if they trained each other, cannot activate a mega stone. It is impossible. It is a bond between human and Pokemon. Two different creatures. That is what is written, and so that is how it is. That is the only reason I've raised an objection on this. Plus, if you can do it, then everyone else has to be able to do it too to make things fair, which might cause much confusion to other players. I mean, you've done it once just now, and look how much confusion there is now
