The Opelucid City Gym is the final Gym to be challenged in the Unova region. Unlike most games, this Gym has two different Gym Leaders, but it is dependent on which version you, the player, have. In Pokémon Black version, the Trainer has to battle Drayden, the Mayor of Opelucid City. On the other hand, in Pokémon White Version, the Trainer alternatively has to battle Iris. Both specialize in Dragon-type Pokémon, and so do their Gym Trainers. However, in Black 2 and White 2, this gym is the seventh to be challenged. The Trainer has to reach Drayden by riding on top of a dragon statue that is the opposite color of the version the player is playing.
