I'm not sure how subtle an out-maneuver 'wait until he's crippled and bedridden and THEN kill him and take his powers' is, or how on earth that qualifies as him being ina different power sphere at all, but OK, I guess we can roll with this if that's what you want.

I didn't respond to any of the rest of it because it either wasn't relevant or, frankly, worth responding to.
