Weird Worlds published features based on writer Edgar Rice Burroughs' creations which DC had obtained the licensing rights.

This included the "John Carter of Mars" feature, by scripter Marv Wolfman and artist Murphy Anderson, which moved from Tarzan #209, and the "Pellucidar" feature from Korak, Son of Tarzan #46 drawn by Alan Weiss, Michael Kaluta, and Dan Green.

The release of the last issue of Weird Worlds was delayed for several months due to a nationwide paper shortage.
