Than Kosis

A villain of the Martian wastes, Than Kosis made his comics debut in Dell's Four Color #375 in 1952, adapted from Edgar Rice Burroughs' beloved Barsoom saga by Paul S. Newman and Jesse Marsh. This Golden Age antagonist keeps genuinely iconic company — sharing the page with John Carter, Dejah Thoris, and Tars Tarkas — which speaks to his place at the heart of the Martian epic's most dramatic conflicts. Though his catalog appearances are few, the fact that his presence echoes across six decades of comics publishing, from Dell's classic run all the way through John Carter: World of Mars in 2012, marks him as a figure whose shadow falls long over the red planet's lore. For collectors chasing the full Barsoom tapestry, Than Kosis is one of those satisfying corner pieces.
