Re Sonja, the She-Devil with a Sword, is a fictional character, a low fantasy sword and sorcery heroine created by Roy Thomas and Barry Windsor-Smith. She first appeared in Conan the Barbarian #23 (Marvel Comics). The character was loosely based on Red Sonya of Rogatino in Robert E. Howard's short story "The Shadow of the Vulture" (The Magic Carpet, January 1934), which Roy Thomas rewrote as a Conan story for the Marvel comic.
