Fafnir

Few characters can claim they've been sharing pages with Conan the Barbarian since the very early Bronze Age, but Fafnir is one of them — debuting in Conan the Barbarian #6 back in 1971, brought to life by the legendary creative duo of Roy Thomas and Barry Smith. That first appearance carries collector-significant weight as a recognized key issue, making it a genuine prize for fans of Marvel's sword-and-sorcery era. Though Fafnir's footprint in the catalog is compact, their place in that rich Hyborian world — alongside figures like Conan himself and other denizens of those savage, mythic adventures — gives them a real piece of comics history. If you're building out your Bronze Age Marvel shelf, this is exactly the kind of discovery that makes the hunt worthwhile.
