Another I love is ARAK by Roy Thomas (circa 1981-1985). And though he didn't quite make it, he did have a respectable 50-issue run, plus an annual or two.
ARAK was created when Roy Thomas left Marvel because of Shooter, and then contracted to do work for DC. That's when he started ALL STAR SQUADRON (so he could play with DC's Golden Age heroes), and to get his Conan fix, he created ARAK. I love the concept (contrary to the normal direction of migration) of a native American sailing over to Europe, adapting to Scandinavian/Viking life, and then exploring the rest of Europe. The only part I didn't like were the injected mythological characters. I would have preferred the series (with more historic accuracy) to just have the character explore the wars and kingdoms of Europe, Africa and Asia in that era. That to me would have been more engaging than Satyrs and winged horses and so forth.

I especially recommend ARAK 1 and 2. And the preview story in WARLORD 48.



But a very respectable run, as failed characters go. And while somewhat visually similar, far from just a rip-off retread of Conan.

To my knowledge, there have been no revivals.
