I have an idea for a DPPt hack, but it may have some holes in it..:
You are the champion. You beat Team Aqua. You've done everything there is to do. You have won. You sat bored one day on your new throne, thwarting the challengers easily.
But you notice something. Everyone around you is dying. You hear a voice booming around you: NEW GAME.
it repeats itself over and over. you black out. All of a sudden, you are back where you started. A starter, a 'dex, no badges. This time, you don't go after the league. THIS time, you go after the voice you heard.In order to reclaim your old team, You go after god himself :Arceus.
