The Church of Blood was a secret following founded by Roger Trigon, later led by Sebastian Blood. In reality, Blood acted on the orders from Slade Wilson, who used the cult as means to find and recruit people able to withstand the effects of Mirakuru, whom Slade would use for his army. Blood eventually abandoned Slade Wilson after seeing the danger Slade's Mirakuru soldiers posed to the city, only to be killed by Isabel Rochev for his betrayal. After Slade was imprisoned by A.R.G.U.S. and Isabel was killed, leadership of the Church was taken over by Clinton Hogue, who claimed the mantle of Brother Blood.
