Roxanne

"Hello, I am Roxanne, the Rustboro Pokémon Gym Leader. I became a Gym Leader so that I may apply what I learned at the Pokémon Trainer's School in battle. Would you kindly demonstrate how you battle, and with which Pokémon?"-Roxanne, Pokémon Ruby, Sapphire and Emerald.

Roxanne (Japanese: ツツジ Tsutsuji) is a type Gym Leader in the Hoenn Region. She also teaches at, and helps run the Pokémon Trainer's School in Rustboro City. Her Gym is in Rustboro City. She will award the player with the Stone Badge if he/she defeats her.

Ruby and Sapphire Chapter
She battles against Sapphire and loses, though she forgets to tell her that if you collect all badges you can battle in the Hoenn Pokémon League.

Afterwards, during when all the Hoenn Gym Leaders had a meeting, they talked about which Team is good, Team Magma or Team Aqua. Though in the end, both Teams were causing mayhem in the entire region.

Trivia

 * Roxanne's name is a play on the word, since she is a Rock-Type trainer. Brock and Roark may also share this pun. (Brock: take away the B, leaving rock, and Roark: take away the 'a' and the second 'r' and you get Rok, which can be translated to "rock".)
 * Roxanne is the only 'female' Gym Leader that specializes in Rock-type Pokémon.
