Zygarde doesn't get the treatment (RIP minty fresh Zygarde ;-;), but maybe this means the upcoming Pokemon games will un-shinylock him too.The first images from CoroCoro have leaked and have revealed some details about distributions to coincide with Pokémon XY & Z. These distributions will run weekly and will be obtained by a serial code obtained during the Pokémon XY & Z anime. On October 29th, a shiny Xerneas will be obtainable. It is Level 100 with the moves Geomancy, Moonblast, Aromatherapy and Focus Blast. On November 5th, a code for a shiny Yveltal will be distributed with the moves Oblivion Wing, Sucker Punch, Dark Pulse and Foul Play and on November 12th, a code for a Zygarde will be distributed with the moves Land's Wrath, Extreme Speed, Glare & Outrage. We'll bring more as it comes
