Xena is a fictional character from the Xena: Warrior Princess franchise, portrayed by New Zealand actress Lucy Lawless and co-created by Robert Tapert and John Schulian. She first appeared as a villain in the 1995–1999 television series Hercules: The Legendary Journeys before joining forces with Hercules. Xena was popular with fans, so the producers decided to create a spin-off with the character in the starring role. She later appeared in the subsequent comic book of the same name, as well as the spin-off animated film The Battle for Mount Olympus, and non-canon expanded universe material, such as books and video games.
