I also thought of a plot twist for the tournament, early micheal said something about finding a weak spot on Nero with the shadow walking. If they got into a fight for whatever reason and if he used it on him, this is what would happen. Nero would once again feel his energy being drain and the denomic keys clawing out of the area of where there trapped, if he doesn't get out of there soon the demons will force there way out and then you will have to face about 5 NEARLY immortal demons, kal,shan, and a unconscious Nero.
