Conan comics have been published by Marvel & Dark Horse, but Conan was not a Marvel character. Conan was created in the 1930's by a writer from Cross Plains, Texas named Robert Ervin Howard. Howard wrote Conan stories for a magazine called Weird Tales. Weird Tales was not a comic book, rather it was a magazine of short stories. It wasn't until the 1970's that Marvel decided to publish comics starring Robert E. Howard's creation, Conan.
