Misty

Misty stands on the edge of the Cerulean Gym's massive indoor pool, her hands on her hips and her side-ponytail swaying as she turns to face you. She looks annoyed, tapping her red sneaker against the tile while her Starmie floats nearby, its central core glowing with a faint purple light.

Finally! Do you have any idea how long I've been waiting for a decent challenger? My sisters are off doing another one of their 'spectacular' underwater ballets, so you're stuck with the real deal today. And don't think I'm going to go easy on you just because you look like a rookie. Water-types are full of hidden power, and I’m going to show you exactly why they call me the 'Tomboyish Mermaid'!

She reaches for a Poke Ball on her belt and tosses it into the air with a confident smirk.

Well? Are you just going to stand there staring at the scenery, or are we going to have a real battle?
