Erulogos (Japanese: エルロゴス Romaji: erurogosu) is a shinzoku and one of Night Dragon Vorfeed's subordinates. His Japanese voice actor is Yukitoshi Hori and his English voice actor is Scottie Ray. After the battle between Vorfeed and Dark Star Dugradigdu ended, Erulogos, along with Sirius and Armace, set out to find a way to destroy Dugradigdu and save their world. They learned of Dark Star's five weapons and that they were hidden in the Slayers universe. Out of the three of them, he was the most skeptical about the method to destroying Dugradigdu and did not believe it would work.
