Moreau is an alcoholic warrior monk, part of an ancient monastic order tasked with protecting the child of Roarke on Earth and preventing the demon from transferring his essence into the boy. He believed they would need the help of the Ghost Rider but his superiors disagreed. When their stronghold was attacked by Roarke's mercenary forces led by Carrigan, he lost track of the child and his mother. Moreau himself went to visit the Rider's host, Johnny Blaze; and offered him a deal. If he agreed to find the child and deliver him to Moreau, he would have his order remove Blaze's curse. After retriving the child, Carrigan, now empowered by the devil, killed all the monks, that were planing to kill Danny, the child, for representing a threat to mankind as the son of the devil, and took him. At Danny's rescue, Moreau was killed by Carrigan.
