Here's Gold Key's Dagar, The Invincible #1, a book that I'm pretty darn sure was created to compete (or at least get part of the market) with Conan the Barbarian, except for a perhaps younger audience.
I believe that Donald Glut created Dagar as well as his fellow Gold Key comic book star Dr. Spektor... and in fact, I believe it was revealed in some comic or another that Dagar was Spektor's ancestor!
I don't recall reading many Dagar issues, however... I am a Spektor fan, though!
I am a former graphic designer turned medical assistant turned truck driver who's into comics, sf, tv, cartoons, monsters, oldies rock, and lots of other stuff.
