Brother Blood
The first Brother Blood encountered by the Titans was the eighth to bear the title. Seven hundred years earlier, a priest in the fictional nation of Zandia named Brother Sebastian killed another priest to gain possession of what he believed to be Christ's prayer shawl. The shawl gave him invulnerability and reduced his aging, but the priest he killed cursed him to be slain by his son before his hundredth birthday. Upon doing so, his son became the second Brother Blood. He, in turn was killed by "his" son, and this continued for seven centuries.
