The protagonist has turned twelve and is going to get first pokemon from a nearby professor. The protagonist arrives the lab at the outskirts of the city through a road on a bicycle.
On arriving protagonist gets the pokemon he or she wanted with pokeballs and pokedex all at a time. A battle with the rival ends the scene at the lab. The protagonist goes to parents and shows the pokemon and gets running shoes. Protagonist sets on the journey to become the greatest pokemon trainer in the region.
If you agree this I have another idea which would move from the regular gameplay.
I like this but I will wait for JNathan's strory so I can choose one of them
