You have to make your own regional Pokedex out of existing Pokemon. 150 Pokemon. 9 are starters, must be fire/water/grass 3-stage evolutions. At least 2 shitmons for the early game. At least 5 legendaries.
This region will be the start of a new Pokemon continuity. All Pokemon you didn't choose will be lost forever. Who doesn't make the cut?
