For being eighty years old, the literary character, Conan the Cimmerian, holds his own incredibly well. I must admit my first introduction to Conan was through the 1982 Arnold movie, and let's be honest, that was a pretty awesome movie. It wasn't until much, much later that I got into the Robert E. Howard stories, comics, and more.
Conan is an excellent iron-age hero steeped in the low magic, sword and sorcery world of Hyboria, and excellently detailed and historical rich mythos created by Howard. Reading the books you get a better sense of the character, his humorous side and the like, but I've been pretty happy with most of his appearances across all the various mediums. Brains and brawn, well, mostly brawn and the strength of arm to fight cultists, critters, and slavers all head on, Conan is an easy shoe-in to the Thor's Day Heroes.
