If nobody else steps up, I'm up for this guy being Evil World Overlord (or having a part in thereof). At the same time if someone else would prefer to take that spot I am super down with him basically sealing off his place from everything else (or dying in the attempt).

I'm also up for him having a direct hand in the events that led up to whoever the Evil World Overlord is; that is, doing something that needs to be stopped here and now to prevent ~the future~!
