These features ran until issue #7 (October 1973) until it became economically infeasible for DC to continue publishing so many adaptations of Burroughs' work.[5] "John Carter" would re-appear in Tarzan Family #62–64 and "Pellucidar" in Tarzan Family #66.
A new feature began in issue #8, Dennis O'Neil and Howard Chaykin's Ironwolf,[6] which ran through issue #10. The release of the last issue of Weird Worlds was delayed for several months due to a nationwide paper shortage.[7] The Weird Worlds stories were reprinted in an Ironwolf one-shot in March 1987.[8]
Second series
The title was relaunched in March 2011 and ran for six issues.[9] It featured Lobo and two new characters: Aaron Lopresti's Garbage Man and Kevin Maguire's Tanga.
In September 2011, The New 52 rebooted DC's continuity. In this new timeline, the characters appeared in the title My Greatest Adventure.
