Elesa

 Elesa (Japanese: カミツレ Kamitsure) is Gym Leader of Nimbasa City's gym of the Unova region. This gym will be the fourth to be challenged by the player. She specializes in -type Pokémon. She will award the player the Bolt Badge if you defeat her. Her first appearance was in Pokémon Black and White. She is also a fashion model besides being a gym leader.

In the games
In the games, after the player exits the Pokémon Musical for the first time, Bianca's father comfronts her and tells her to go home with him. However, Elesa steps in and convinces Bianca's father to let her continue her journey. This makes Bianca admire Elesa and makes her want to be a model just like her. She then tells the player she's waiting in the gym for him/her. After defeating her, she goes out to Route 5 and contacts Clay, telling him to bring the Drawbridge down. When it does come down, she wishes the player good luck and returns to the gym.

She next appears along with the rest of the Unova Gym Leaders, with the exception of Cilan, Chili, and Cress, and battle (?) the Seven Sages, allowing the player to continue.

For the rest of the game, she can be found in her gym.
