vs. the keystone from the anime:
I just realized that thing on his glasses might be a keystone...
It looks like it might be....and then he puts his hand on it.....so maybe.... *crosses fingers*
edit:
According to Peke...this is old news...but I just found out about it
A key stone is a necessary item in order for your Pokemon to mega evolve? If he has a key stone, that means his Pokemon has a Mega Stone as well. Or it's intended for Primal Groudon/Kyogre(?)
I hope they don't fwak it and give them one of the known Mega Pokemon in X/Y(like Gyarados) ---> mind=blown
Also, the key stone looks gay. It looks like a bilye/marble toy; couldn't they had thought of a better design. I GOT INFINITE KEY STONES. I CAN HAZ MOAR THAN 1 MEGA POKEMON. WHERE IS YOUR GOD NOW?
