The "Eternal Champion" is a fictional character created by author Michael Moorcock. He serves as a central figure in a series of fantasy novels, embodying the struggle between good and evil across various universes. The character often takes on different identities, such as Elric of Melnibone and Corum Jhaelen Irsei, each representing different aspects of heroism and moral conflict. The concept of the Eternal Champion is tied to the idea of a cyclical battle against chaos, with the character reincarnating in different forms to restore balance. This theme is prevalent in Moorcock's works, influencing the genre of sword and sorcery and inspiring many other authors and creators in fantasy literature.
