Abel Nightroad on the surface, he appears to be a clumsy, absent-minded and very compassionate Catholic priest who has bad luck with money and is always hungry. In reality, he is a Crusnik, a vampire with extraordinary powers that feed especially on other vampires. Nearly a millennium in age, Abel was created in 2088 A.D. as one of four test tube babies whose bodies were infused with Crusnik nanomachines by the Mars human colonists. Abel once had a hatred for humanity and joined the Methuselah in the war against humans after the Armageddon. This prejudice was presumably the result of an unexplained betrayal that was mentioned by a holo-recording of Lilith. During the war between the humans and Methuselah, Abel Nightroad killed seven million humans. Lilith's murder by Cain caused him to abandon the war. He spent 900 years weeping and mourning in Lilith's crypt at the Vatican, until a young Caterina Sforza fled there to escape Methuselah assassins. Abel, deciding then that it was his task to continue Lilith's work and defend the humans, saved the young Caterina and chose to live on. He joined the AX at its foundation in May 3055 A.D. He is described as looking around 20 years old in the manga, and has long silver hair and blue eyes. (information used from wikipedia)
