There were some indications in KC itself that his years of exposure and age made him even stronger. That and in JSA this week there are some indications he is a notch above current Superman. So anyone have any speculation on where he is on the scale? And what are you overall impressions of his showing up at all?

Waid didn't give us any benchmark of his strength in either Kingdom Come or The Kingdom -- his Superman didn't perform any feats to go by, in other words. We know Waid's Superman had an enhanced resistance/immunity to Kryptonite, but whether KC Kal had current Superman's level of strength, invulnerability, etc., is anyone's guess.
