With Pokémon fans already counting down the days to the October 12th worldwide launch of Pokémon X andPokémon Y for the Nintendo 3DS family of systems, an extremely rare and exciting opportunity to receive your own Shiny versions of the Legendary Pokémon Dialga, Palkia, and Giratina begins today in the U.S., only at participating GameStop stores. Head to GameStop and get a Level 100 Dialga until September 8th. Catching a Legendary Pokémon is difficult enough under normal circumstances, but this particular Dialga is Shiny—it has different coloring that almost never appears when players encounter it in Pokémon Diamond, making this limited-time event even more extraordinary. While at GameStop, Pokémon fans can pre-order a copy of Pokémon X or Pokémon Y.

Fans can return to GameStop starting September 9th to get a Level 100 Palkia, a Legendary Pokémon encountered in Pokémon Pearl. This Palkia is also a Shiny Pokémon with unusual coloring. Rounding out this trio of limited-time events will be the distribution of a Level 100 Giratina beginning September 30th at GameStop stores, a Legendary Pokémon that is encountered in both Pokémon Diamond and Pokémon Pearl. Like Dialga and Palkia, this Giratina is also Shiny. Each Shiny Legendary Pokémon is available for only three weeks each, so Trainers will need to plan accordingly to take advantage of this special opportunity.
