The method for Japanese players of Pokémon Diamond and Pearl to obtain the legendary PokémonDarkrai was revealed recently, according to a flier posted by Filb.de. Darkrai will be distributed to attendees of the 10th Pokémon movie, Dialga vs. Palkia vs. Darkrai, via local Mystery Gift at Japanese movie theaters July 14 through Sept. 9.
The item to unlock an island in the games where Darkrai can be caught, the Member's Pass, will apparently not be distributed. Instead, players will directly download the Pokémon with Mystery Gift. Darkrai will be inside a Cherish Ball (プレジャスボール Precious Ball), a normally unobtainable Poké Ball, and will be holding an Enigma berry, also normally unobtainable. Darkrai will have a Classic Ribbon (クラシックリボン) and will know the moves Roar of Time and Spacial Rend, moves normally exclusive to Dialga and Palkia, respectively.
