AZRAEL

Azrael is a vigilante mantle in DC Comics, most famously held by Jean-Paul Valley Jr. and later Michael Washington Lane. Genetically engineered and brainwashed by the Sacred Order of Saint Dumas via subconscious conditioning known as 'The System,' Jean-Paul initially served as an assassin before becoming an ally to Batman and briefly assuming the dark knight's cowl during the legendary Knightfall arc.
