Man, no horror or sword and sorcery character was safe from 1970's Marvel.

Marvel, a world where vampires come from Atlantis. You just got to love how insane it can get. The same Atlantis whose destruction led to Conan the Barbarian's age, and the same Atlantis which would later become home to Namor the Submariner

The destruction of Atlantis leading to the Hyborian Age in Conan the Barbarian was actually canon in the original Robert E. Howard Conan stories. The idea didn't originate with Marvel.

PS: So Doctor Strange can do all that stuff and he can't heal a bullet wound? (i will Always be a bit salty about One More Day)
