Brother Blood is the name of two fictional supervillains appearing in American comic books published by DC Comics. The first iteration, Sebastian Blood VIII, is a power hungry priest and the head of the Church of Blood, as well as the eighth person in the DC Universe to assume the mantle, after killing his father and taking the Brother Blood mantle from him. This tradition had gone on for generations, dating back to the 13th century, when the first Brother Blood was born after obtaining Christ's prayer shawl and gaining superhuman abilities. As Brother Blood, Sebastian served as a recurring adversary of the Teen Titans, until being killed by his successor, Sebastian Blood IX. He is also the archenemy to the superhero, Cyborg, a member of both the Teen Titans and the Justice League.
