>>119671245Waid wrote Kingdom Come, involving a version of Superman overcome with guilt and an inferiority complex, to such an extreme degree that he gave up being a hero for many years, despite being able to hear people's cries for help.
Then he wrote an origin story for Superman in which he was a vegan, who lacked the ability to understand his Kryptonian heritage, and threatened humans with guns. This origin story was so poorly received, it was never implemented into canon.
That was all the Superman Waid ever wrote, unless I'm mistaken. Waid's career at DC mostly involved writing Wally West Flash books. Then he went on to write Irredeemable, about a Not-Superman figure who loses his marbles and turns EEEEEEVILLLLLL. This is a man who should not be allowed near Superman at any cost.
