Dark Horse Comics has published various Tarzan series from 1996 to the present, including archive reprints of works from previous publishers such as Western/Gold Key and DC. Dark Horse and DC published two crossover titles teaming Tarzan with Batman and Superman. Batman/Tarzan: Claws of the Cat-Woman is a "straight" team-up between Tarzan and the 1930s Batman to save an ancient city during which the two form an effective team as they acknowledge their similar origins, despite such differences as Tarzan's willingness to use lethal force. Superman/Tarzan: Sons of the Jungle is a revisionist version in which Lord Greystoke grows up in England, while Kal-El is raised by the apes as "Argozan", although the two switch roles at the conclusion with Greystoke remaining in the jungle while Kal-El returns to the city, Greystoke stating in a letter to his parents that he feels as though he has found his true place. Tarzan also fought the Predators in the Tarzan vs. Predator: At the Earth's Core miniseries.
