Sebastian Blood VIII, known by his alias, Brother Blood, is a supervillain appearing in American comic books published by DC Comics. He is a power-hungry priest and 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 Jesus of Nazareth's prayer shawl and gaining superhuman abilities. As Brother Blood, Sebastian served as a recurring adversary of the Teen Titans before being killed by his successor, Sebastian Blood IX.
Brother Blood appears in the 2003 Teen Titans animated series and its 2013 spin-off Teen Titans Go!, voiced by John DiMaggio. Sebastian Blood is a recurring character in the second season of the Arrowverse series Arrow, portrayed by Kevin Alejandro. Joseph Morgan appears as the character in the fourth season of the HBO Max series Titans.
