Really shake things up. You start at the league champ, and have to fight your down, going through the entire game backwards. At the end you hand in your last remaining Pokemon to the professor, who thanks you with a heartfelt speech before pulling out her device that resets your memories and de-ages you. Then you play through the game again as normal.
When you defeat the champion at the end, your character starts to remember what hapened, and that's when the Shadow Triad jumps out from the shadows and knocks you unconscious, dragging you away. You wake up in a cave and see Kyurem. Hungry. You can't escape as you're chained to the wall and can only squirm as Kyurem slowly walks over to you. The screen goes black... a single flash of white light... The screen fades to red.... then nothing.
No buttons work, you have to reset the game. When you get back to the main menu, your file has been deleted. When you press New Game, the Shadow Triad appear for a split second. That's when you feel someone standing right behind you
