Pokemon Sunday just finished airing and showed a few clips from Black and White‘s Battle Subway; you can watch a low-quality video of the segment below. They revealed that if you keep winning battles in the Battle Subway, a new character named the Subway Master appears presumably to challenge you (seen at 0:30 below). He is apparently the Palmer of the Battle Subway. Until the release of Black and White, Pokemon Sunday will be revealing something new about the games at the end of each episode. Next week they will be showcasing Pokemon Musicals.
