Daniels observed that "O'Neil's interpretation of Batman as a vengeful obsessive-compulsive, which he modestly describes as a return to the roots, was actually an act of creative imagination that has influenced every subsequent version of the Dark Knight." O'Neil and Adams' creation Ra's al Ghul was introduced in the story "Daughter of the Demon" in Batman #232 (June 1971). O'Neil and artist Bob Brown also created Talia al Ghul. During this period, O'Neil frequently teamed up with his regular collaborator Adams (with Giordano often assisting on inks) on a number of memorable issues of both Batman and Detective Comics. The creative team would revive Two-Face in "Half an Evil" in Batman #234 (Aug. 1971) and revitalize the Joker in "The Joker's Five-Way Revenge!" in Batman #251 (Sept. 1973), a landmark story bringing the character back to his roots as a homicidal maniac who murders people on a whim and delights in his mayhem. O'Neil and Giordano created the Batman supporting character Leslie Thompkins in the story "There Is No Hope in Crime Alley" in Detective Comics #457 (March 1976). O'Neil and artist Don Newton killed the original version of Batwoman in Detective Comics #485 (Aug.–Sept. 1979). He wrote a short Christmas story, "Wanted: Santa Claus – Dead or Alive", for DC Special Series #21 (Spring 1980) which featured Frank Miller's first art on a Batman story. When Julius Schwartz became the editor of Superman with issue #233 (Jan. 1971), he had O'Neil and artist Curt Swan streamline the Superman mythos, starting with the elimination of kryptonite. In 1973, O'Neil wrote revivals of two characters for which DC had recently acquired the publishing rights. A new series featuring the original Captain Marvel was launched with a February cover date and featured art by the character's original artist C. C. Beck. Later that same year, O'Neil and artist Michael Kaluta produced an "atmospheric interpretation" of the 1930s pulp hero in The Shadow series. In 1975, O'Neil wrote a comic book adaptation of the 1930s hero the Avenger. A revival of the Green Lantern title in 1976 was launched by O'Neil and artist Mike Grell. Reuniting with Adams, O'Neil co-wrote the oversize Superman vs. Muhammad Ali (1978) which Adams has called a personal favorite of their collaborations. Return to Marvel Comics Upon O'Neil's return to Marvel Comics in 1980, he took on the scripting chores for The Amazing Spider-Man, which he did for
