God-Emperor is the title associated with Leto Atreides II after he ascended to the throne of the Atreides Empire. The title reflects both his status as ruler of multiple galaxies, and the formidable prescience powers he acquired after his transformation to a human-sandworm hybrid. The title did not endure well after his death. During his life Leto II's enemies referred to him as The Tyrant, and it was this title by which history better remembered him. This title is incorporated into the name of the novel God Emperor of Dune without the hyphen.
