In a lab in Kalos, a teenage girl is hard at work measuring out strange substances in vials and mixing things together. Only a few lights are on and all the curtains are closed so nobody can peep in. In the dim light, there are cages stacked up with various small Pokémon, especially Pikachu.
The girl has long blonde hair and is wearing a shirt with a single star printed on it. Over the shirt she is wearing a long white lab coat with deep pockets.
"Look, I know I messed up last time..." the girl says as she opens a cage, "But I've done more research since... I'm sure I've got the right combination this time!"
She grabs a shiny female Pikachu from a cage and smiles.
"Pika!" the Pikachu complains, struggling to escape from the scientist.
"Hold still you brat! I'm only trying to help you!" the girl yells.
The angry Pikachu reluctantly sits still on the lab table. The girl grabs a vial and is just about to use it when suddenly, a loud knock is heard on the door. Frightened, she accidentally drops the vial and soaks the Pikachu and herself. The knocking gets louder.
"This is the police! Open up!" a voice calls.
A flash of light occurs and the scientist falls with a thud onto the floor.
"Ouch... Ugh... What... What is this...?" she asks.
It was the wrong formula again! This time, the serum has fused her with the Pikachu!
"Not good!" she squeaks.
The police break down the door so she quickly grabs some vials and shoves them into the lab coat she is still wearing. As the police are searching the front of the lab, the girl, now a Pikachu, escapes through the window and runs away.
