Red Sonja, the She-Devil with a Sword, is a fictional character, a high fantasy sword and sorcery heroine created by Roy Thomas and Barry Windsor-Smith. She first appeared in the Marvel Comics's Conan the Barbarian #23 (February 1973).
Red Sonja has become the archetypical example of the fantasy figure of a fierce and stunningly beautiful female barbarian who typically wears armor resembling a bikini or lingerie.
The character now appears monthly in her own series, Queen Sonja, as well as a series of mini-series and one-shots, all published by Dynamite Entertainment.
