Pick up a Powerhouse Pokémon!

Be sure to bring your system from the Nintendo DS family or your Nintendo 3DS system, and your copy of Pokémon Black Version, Pokémon White Version, Pokémon Black Version 2, or Pokémon White Version 2 game when you attend the Pokémon Winter Regional Championships on January 20th. There, you'll be able to get a powerful Cloyster like the one Junior Division player Abram Burrows used to win the Pokémon World Championships! In addition to having the same move set, this Level-30 Cloyster shares the same Nature, Ability, and held item as the one on Abram's championship team. Remember that you don't need to participate in the tournament to get this Cloyster!

Cloyster is just the first Pokémon that will be available via local distribution at upcoming Video Game Championship Series events.
