Misty

Misty is the former Cerulean City Gym Leader. She's an expert when it comes to water-type pokemon's. You first met Misty when you began your pokemon journey in the Kanto region. At first, she had a bit of an attitude towards you when you accidentally wrecked her bike, but soon discovered she's actually a caring girl who tagged along with you. When you arrived at Cerulean City, you soon discovered that Misty was originally the gym leader, but she decided to let her sisters take over while she was gone.
