Why can't I trade my Shiny Beldum from Alpha Sapphire to X?

Question

I started my game in japanese and got the shiny beldum, but now I want to trade it back to X to restart my game. However, whenever I try to trade my beldum from sapphire, it says some weird thing in japanese and won't let me show my beldum for trade. please help!

Answer 1

The reason that Beldum can't be traded is because it is holding a Metagrossite. Since Mega-Metagross has not been introduced to XY, it's mega stone is incompatible with the Kalos games. Once you take the Metagrossite from the Beldum you will be able to trade/ transfer it to XY.
