The first comic book published under the title "Legion of Super-Heroes" was a four-issue series published in 1973 that reprinted Legion tales from "Adventure Comics". In the same year, the Legion returned to cover billing on a book when "Superboy" became "Superboy starring the Legion of Super-Heroes" with #197 (August 1973). Crafted by Bates and Cockrum, the feature proved popular and saw such events as the wedding of Bouncing Boy and Duo Damsel in "Superboy" #200 (Feb 1974). Issues #202 (June 1974) and #205 (Dec. 1974) of the series were in the 100 Page Super Spectacular format. Cockrum was replaced on art by Mike Grell as of issue #203 (August 1974) which featured the death of Invisible Kid. With #231 (September 1977), the book's title officially changed to "Superboy and the Legion of Super-Heroes" and also became a "giant-size" title. At this point, the book was written by longtime fan Paul Levitz and drawn by James Sherman, although Gerry Conway frequently wrote as well. Saturn Girl and Lightning Lad were married in "All-New Collectors' Edition" #C-55 (1978), a treasury-sized special written by Levitz and drawn by Grell. In #241–245 (July–December 1978) Levitz and Sherman (and then Joe Staton) produced what was at that time the most ambitious Legion storyline: "Earthwar", a galactic war between the United Planets and the Khunds, with several other villains lurking in the background. During this period, Karate Kid was spun off into his own 20th century-based self-titled series, which lasted 15 issues. Levitz left the book, to be replaced full-time by Gerry Conway.
