I want an orre game where you can keep shadow pokemon, and transfer them over to the newest games as different form pokemon. Shadow pokemon get their unique typing(Along with moves). Super effective against everything(shadow moves not very effective against shadow pokemon). To balance them out, they would have different abilities, movepools they could learn, and would go "Berserk" when down to 25-40% health, essentially disobeying the trainer as they did back in the GC games. Unique shadow legendary pokemon, like shadow lugia, would not disobey trainers, essentially acting like a completely new legendary pokemon
