Batman
The first Batman story, "The Case of the Chemical Syndicate", was published in "Detective Comics" #27 (May 1939). Finger said, "Batman was originally written in the style of the pulps", and this influence was evident with Batman showing little remorse over killing or maiming criminals. Batman proved a hit character, and he received his own solo title in 1940 while continuing to star in "Detective Comics". By that time, Detective Comics was the top-selling and most influential publisher in the industry; Batman and the company's other major hero, Superman, were the cornerstones of the company's success. The two characters were featured side-by-side as the stars of "World's Finest Comics", which was originally titled "World's Best Comics" when it debuted in fall 1940. Creators including Jerry Robinson and Dick Sprang also worked on the strips during this period.
Batman: Anarky
The first appearance of Anarky was in "Anarky in Gotham City", "Detective Comics" #608, in November 1989. Grant's initial script portrayed Anarky as vicious, killing his first victim. Dennis O'Neil, then editor of "Detective Comics", balked at this proposal, believing that the depiction of a twelve-year-old becoming a murderer was morally reprehensible. Grant consented to O'Neil's request that the script be changed, and rewrote it to portray Anarky as violent, but non-lethal. Grant later expressed relief with this early decision, coming to believe that "Anarky would have compromised his own beliefs if he had taken the route of the criminal-killer."
