Character: Zekrom

Zekrom is the Deep Black Pokémon (Black Yin Pokémon in Japan), and is the mascot for Pokémon White. It resembles a black dragon, with wing-like formations on its forearms. Its tail resembles an electric generator. It has the ability to travel through thunderclouds and cause storms.

At the climax of Pokémon White, the player must capture Zekrom and use it to defeat N's Reshiram, while in Pokémon Black the roles of the two dragons are reversed.

Zekrom appears in the first two episodes of the Best Wishes! season of the Pokémon anime and the film Pokémon the Movie: White—Victini and Zekrom. In Pokémon Black and White Version, its arms legs and tail glow blue.

In the Reshiram movie, Zekrom befriends Damon. In the Zekrom movie, Zekrom befriends Ash.
