You and your pokemon are walking side by side when a light flashes above you and strikes down on both of you. You hug your pokemon tightly and open your eyes after it's over. But your pokemon is gone! You look into a lake and notice you have morphed with it. Then a Pelipper flies by and drops you a letter:
Dear (name),
I'm so sorry for what has happened. I have created an experiment but it spread out because it was unstable. There is a school I created for people like you. I hope you can attend.
Principal Mewtwo

I will play as Kachu (in the picture but girl style)
