Although DC had initially announced Marc Guggenheim as writer of the title following the "War of the Supermen" limited series, he was replaced by Paul Cornell. Cornell featured Lex Luthor as the main character in "Action Comics" from issues #890–900 and Death appeared in issue #894, with the agreement of the character's creator, Neil Gaiman. In April 2011, the 900th issue of "Action Comics" was released. It served as a conclusion for Luthor's "Black Ring" storyline and a continuation for the "Reign of Doomsday" storyline. The final issue of the original series was "Action Comics" #904.
