(Yeah my first Pokemon Fan fiction on this cite. Ash and the gang are 16 and Bonnie is 10. I don't own Pokemon.)

As Ash, Bonnie and Serena head for Lumious City Pikachu's ears suddenly perk up.

"Pika?" Pikachu says.

"Hey Pikachu what's up?" Ash says noticing his partner's sudden distress.

"Hey you!" Some one shout from behind the trio.

They turned around and saw a girl behind them.

The girl had long black hair that was in a pony tail that stuck out of her black and purple baseball cap. She wore a black t-shirt and a dark blue jacket with elbow length sleeves, had dark capees with a black belt holding her Poke-balls and a pair of blue high tops. On her right shoulder was a female Pikachu. The visor of her cap was low enoth that it covered her eyes, giving her a mysterious vibe. Her skin was the same dark tone as Ash's.

"Who are you?" Serena asks.

"My name is but a label and I have labels. I want to challenge you," She said turning to Ash. "To a one on one battle."

"You're on." Ash says.

They find an open field and stand at separate sides.

"You going to fight with your Pikachu?" The girl asks Ash.

"Yeah, same with you?" Ash asks.

"Nah." She says. She took out a blue and black Poke-ball in replace of the traditional red and white. "Lucario time to shine!" She said. A Lucario came out.

"That Lucario looks familiar." Ash thought.

The battle started. The mysterious girl went first. Lucario used aura sphere on Pikachu. Pikachu returned with eletroball causing Lucario to be pushed back. The fight went on and on till Ash realized home to end it and why the girl and Lucario were so familiar.

"Pikachu use thunderbolt!" He yelled.

The thunderbolt hit Lucario causing it to faint. The girl returned Lucario to its ball.

"You did well take a nice break." She said as she put the ball back on her belt.

"You're really good." Ash said.

"Thanks. You've gotten stronger too bro." The girl says

"Wait did you just call Ash your brother?" Serena asks.

The girl tips her hat up relieving eyes just like Ash's.

"Well of corse. We are twins after all." She says.
