Above is a gallery of Marvel's Thongor series which ran in the former monster-reprint book Creatures on the Loose. Ironically this is a seminal series for fantasy fans because it also ran the first episodes of Gullivar of Mars and debuted King Kull in that great one-off story by Berni Wrightson.
Also heavy on the irony is that it was in fact Lin Carter's Thongor that started the whole barbarian-in-comics surge that in many ways defines the Bronze Age. Figuring there was no way Marvel could afford to license Robert E. Howard's Conan the Barbarian, Roy Thomas began his search looking for ways to get hold of the lesser known (and presumably cheaper) Thongor. When he found out Conan could be done, he dropped poor Thongor, but with this series at last got Lin Carter's homage to both REH and ERB onto the comics page.
As it turns out, Thongor is a pre-Conan hero in another way too, as in the vast scope of the Marvel Universe history as defined here, his adventures pre-date Conan's by some vast number of years, but are connected. Not bad for a largely forgotten knockoff from a then meager genre.
