How to Get Shiny Mega Mewtwo Y in X & Y
A shiny Mewtwo becomes a shiny Mega Mewtwo Y when it Mega Evolves, so these are the routes to Shiny Mewtwo.
Shiny Mewtwo cannot be hunted in X & Y. It is Shiny-locked here and must be brought in from another game.
Shiny-locked when encountered normally in-game (Unknown Dungeon in X/Y). An official Shiny Mewtwo WAS distributed in 2016 as a Play! Pokemon video-game-participant reward: serial codes emailed starting Jul 26, 2016, redeemable Jul 26-Aug 21, 2016 in X/Y/OR/AS. Notable as the first release of Mewtwo with its Hidden Ability Unnerve, holding Mewtwonite Y. Separate regional Shiny Mewtwo distributions also occurred in 2016 tied to National Championships in Hong Kong/Taiwan (Jun 9-Jul 24, 2016) and South Korea (Pangyo Hyundai Department Store, May 5-8, 2016).
