Reshiram debuted in Pokémon Black and White, released for Nintendo DS in 2010 in Japan and 2011 internationally, as the mascot legendary of Pokémon Black. Paired with Zekrom, it represents truth in the games' central theme and is known as the Vast White Pokémon. Its in-game cry, generated with layered tones rather than a voice actor, became a favourite clip for fan-made cry buttons and soundboards. Trainers still share it for team showcases, legendary encounters and nostalgic tributes to the Unova region.
