Eric Draven versus Dorian Grey...
Eric Draven (The Crow) versus Dorian Grey (LXG).
Draven has the Katana he used on Top Dollar's men. Grey has his cane sword.
Fight starts on the ground floor of Hogwarts. On the top floor, in the room of requirement, is the portrait of Grey. Also in the room is the Crow, locked in a cage. The two combatants must fight each other, get to the top floor before the other, and use the painting/crow on the other. (Obviously Grey knows if he kills the Crow Draven becomes mortal, and Draven knows the power behind the painting.)
Who wins?
