(Guess I will post it here.)
For as long as all the world can remember Pokemon have existed alongside humans, looking to each other for strength, hope, and courage, there are many different people in the world and just as many different Pokemon, and finally today, you'll get to meet the Pokemon you've dreamt of since you were young. In this world Pokemon choose their trainers, it's been a good turn for the world of Pokemon because for centuries now there has been peace, no one to truly threaten the world that you live in.
As Pokemon now choose their trainers the age limit is a broad spectrum but for some reason you yourself have had to wait until you were 16, 17, 18 years old to have a Pokemon by your side. You never understood all your friends had left long before, except you and a few others. You and your friends still in town have all had to find jobs, apartments, and lead boring lives thus far. Have you given up on being a trainer? No of course not, but it's starting to look darker and darker to you.
Then it happens there's a tap on your apartment door, you think it's a friend, but no, at your door is a Pokemon Professor, the Pokemon you've kept dreaming of in his hand. It's amazing and to you feels like a miracle.
That isn't entirely the case though the Pokemon Professor has heard about something dark rising far far away from your home region of Kanto. The Pokemon Professor has come to you to ask for help, and because it's finally your turn to become what you've always dreamed. So, what type of trainer are you?
Before I give a CS format I want people's opinions in this idea, it could still use some improvements so feel free to make suggestions!
