Brother Blood is the name of two supervillains appearing in American comic books published by DC Comics. The first iteration, Sebastian Blood VIII, 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, until being killed by his successor, Sebastian Blood IX.
A different iteration of Brother Blood appeared in the 2003 Teen Titans animated series and its 2013 spin-off Teen Titans Go!, voiced by John DiMaggio. Sebastian Blood was also a recurring character on the second season of The CW Arrowverse show Arrow, portrayed by Kevin Alejandro. Joseph Morgan appeared as the character in the fourth season of the HBO Max series Titans.
