Pokémon Black Version and White Version (ポケットモンスターブラック・ホワイト Poketto Monsutā Burakku Howaito?, "Pocket Monsters: Black & White") are role-playing games developed by Game Freak and published by Nintendo for the Nintendo DS. They are the first installments in the fifth generation of the Pokémon series of role-playing games.[6] First released in Japan on September 18, 2010, they were later released in Europe on March 4, 2011, in North America on March 6, 2011 and Australia on March 10, 2011.
Similar to previous installments of the series, the two games follow the journey of a young Pokémon trainer through the region of Unova, as they train Pokémon used to compete against other trainers, while thwarting the schemes of the criminal organization Team Plasma. Black and White introduce over 150 brand-new Pokémon to the franchise, as well as many new features, including a seasonal cycle, fully animated Pokémon sprites and triple battles. Both titles are independent of each other, but feature largely the same plot, and while both can be played separately, trading Pokémon between both of the games is necessary in order to complete the games.
