Watchmen was a 12-issue limited series comic released in 1986-1987 by DC Comics and written by Alan Moore and drawn by Dave Gibbons.
There were numerous attempts to adapt the comic into both a TV show and film, but all failed until 2009's Watchmen directed by Zack Snyder.
His successful run led him to write two issues of Superman -- For the Man Who Has Everything and Whatever Happened to the Man of Tomorrow?
He has no superpowers, but he does have an unshakeable sense of justice that leads him to cripple, maim and kill any criminal.
Both were detectives, with the former known for wearing a mask that makes him look faceless.
He was born as Jonathan Ostermann, and an accident caused him to change into a being who could control matter to create or destroy anything.
