Leto II the Elder was the first born child of Paul Atreides and his lover (and later concubine) Chani. He was murdered in infancy by Glossu Rabban Harkonnen during a Sardaukar attack on the sietch where he was being hidden. Leto II the Elder is sometimes also referred to simply as Leto II, and at times Leto II the God Emperor/Tyrant (the twin of Ghanima Atreides) is referred to as Leto III.
