appear on each cover into 1969 (counting Superman on the covers of issues #354–355). Superboy's popularity in Adventure resulted in the character receiving his own title in 1949, when superhero titles in general were losing popularity. Krypto the Superdog debuted in issue #210 (March 1955) in a story by Otto Binder and Curt Swan. In issue #247 (April 1958), by Otto Binder and artist Al Plastino, Superboy met the Legion of Super-Heroes, a team of super-powered teens from the future. The group became popular, and would replace "Tales of the Bizarro World" as the Adventure backup feature with #300, and soon be promoted to its lead. Lightning Lad, one of the Legion's founding members, was killed in Adventure Comics #304 (January 1963) and revived in issue #312. Issue #260 (May 1959) saw the first Silver Age appearance of Aquaman. In Adventure Comics #346 (July 1966), Jim Shooter, 14 years old at the time, wrote his first Legion story. Shooter wrote the story in which Ferro Lad died – the first "real" death of a Legionnaire (although Lightning Lad had been believed dead for a while before) – and introduced the Fatal Five. The Legion feature lasted until issue #380. With the next issue, Supergirl migrated from the backup slot in Action Comics to the starring feature in Adventure and ran until issue #424. The series reached its 400th issue in December 1970 and featured a Supergirl story written and drawn by Mike Sekowsky. As of #425 (December 1972), the book's theme changed from superhero adventure to fantasy/supernatural adventure. That issue debuted one new feature along with three non-series stories, the pirate saga "Captain Fear". The next edition added a semi-anthology series, "The Adventurers' Club". Soon, editor Joe Orlando was trying out horror-tinged costumed heroes such as the Black Orchid, and then the Spectre. Before long, conventional superheroes returned to the book, beginning behind the Spectre, first a three-issue run of Aquaman (issues #435–437, an early assignment for Mike Grell) and then a newly drawn 1940s Seven Soldiers of Victory script (issues #438–443). Aquaman was promoted to lead (issues #441–452), and backing him up were three-part story arcs featuring the Creeper (#445–447), the Martian Manhunter (#449–451), bracketed by issue-length Aquaman leads. He was awarded his own title and Superboy (#453–458) took over Adventure with Aqualad (#453–455) and Eclipso (#457–458) backups. Following this was a run as a Dollar Comic format giant-sized
