In 1959, Archie Comics hired Joe Simon and Jack Kirby (of Captain America fame) to create new superheroes under their Archie Adventure Series line. They started off with a new Shield, Lancelot Strong. DC Comics viewed the character as too similar to Superman, and it was cancelled after two issues.
Kirby & Simon developed a new character, the Fly, which they produced for the first four issues, after which they were replaced by other creators. This title was soon joined by The Jaguar. By mid-1965, the titles were all cancelled.
Only two other titles were published under the Archie Adventure Series, one was the satire title Tales Calculated to Drive you Bats, the last issue of which changed to science-fiction/horror, and the other the short-lived Jughead's Fantasy.
Their Shadow comic (published because Belmont Books, connected to Archie, was publishing new Shadow material), was a kind of bridge between the Archie Adventure Series and the later Radio Comics/Mighty Comics Group material.
