that would be cool... dark link. Only this time, instead of just showing up, he could come out of your shadow and force you to try to kill yourself. Like the shadow wraps around your arm and you really do have to fight yourself, like in evil dead/army of darkness, or idle hands. Then after you show your will power, he comes out fully (perhaps the twilight relm) and you have to fight him on a one on one. After he almost dies, he could get second wind and turn into a shadow of gannon or something. who knows, something like yungs shadow, only EVIL.
