John Carter, Warlord of Mars #20

Issue #20 of Marvel's adaptation of Edgar Rice Burroughs' John Carter, Warlord of Mars drops readers straight into the chaos promised by the cover's bold tagline — "Battle at the Bottom of the World!" The cover, penciled by Dave Cockrum and Ernie Colón and inked by Rudy Nebres, puts a fierce, bare-chested John Carter at the center of a sprawling melee, twin swords raised high as waves of snarling enemies crash against him from every direction. Chris Claremont handles the writing while Ernie Colón provides the interior art, making this 1979 entry a solid convergence of talent on one of Marvel's most adventurous licensed titles.
