Abel Nightroad
(Peter Abel Nightroad) Voiced by: Hiroki Tōchi (Japanese), Troy Baker (English)
The main protagonist on the series,On the surface, Abel appears to be a goofy, clumsy, absent-minded and very compassionate Catholic priest who has bad luck with money and is always hungry. In reality, this surface is a facade for a far more solemn, sober personality, in which his compassion is retained but his other personality traits vanish. Additionally, he is a Crusnik, a vampiric being with extraordinary powers that feeds 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 by person of persons dear to him that was mentioned by a holo-recording by 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 year 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.
In penance for his earlier sins, Abel now adheres to a strict principle of pacifism and has taken a vow not to kill unless he absolutely must (anime only). Though accepting of his Crusnik form, he will generally only use it as a very last resort. After meeting Esther, he is reluctant to use his Crusnik form in a battle for fear of her seeing it and frightening her, and after she does see it for the first time, Abel is extremely distraught. Later he tells her it is the mark of his sins. Notably, in regards to Esther, in the novels and manga, Abel first reveals his Crusnik form during the Star of Sorrow arc, not long after he meets her, and, in the manga, part of her reasons for joining AX is to find out more about Abel (also in the novels and manga, he is nowhere near as distraught for showing her as in the anime). In the anime and novel, he seems to be oblivious to Esther's romantic feelings for him. Asthe seems to have noticed, though, and calls him a dunce for not being bothered by Ion's affections for Esther. While he mostly responds to her with fatherly affection, when he thought she had been killed, he lost control of himself and went into Crusnik form, seeming to delight in killing the Methuselah Radu who he thought had killed Esther. It is Esther that helps him return to normal. This romantic interest by Esther is completely absent in the manga adaptation, which instead portrays Abel's relationship with Esther as much more like that of a father and daughter. Abel eventually learns from Seth that Lilith's killer and his brother, Cain, is still alive and swears to find and kill him, once and for all. After Abel finds and confronts him, Cain defeats Abel and sends him into a near death state. While Esther mourns at Abel's grave, Cardinal Caterina retrieves the nanomachines from Lilith's body and sends Father Tres to take them to Abel in order to revive him. Tres delivers them to Abel's grave, both reviving him and allowing him to achieve 100% Crusnik fusion without the insanity that manifested in Cain. Immediately afterwards, Cain arrives and Abel battles him again, but the fight ends in a draw and Abel must continue his quest to destroy his brother, now joined by Ion Fortuna.
In his human form, Abel fights with an inordinately large and powerful revolver loaded with silver bullets. In this form, he also possesses strength and speed that is at least as superior to a Methuselah's as a Methuselah's is to a normal human. He also appears to have a limited regenerative ability and a great deal of physical stamina, enough to be run through or shot several times and continue fighting. With 40% of his Crusnik nanomachines activated, his eyes become red, his lips turn dark blue, his nails turn into claws, his teeth become fangs, and he can make a gigantic red scythe composed of crystallized blood materialize in his hands. This form also sees a marked increase in strength and speed from his human form, and an enhanced regenerative ability which enables him to heal injuries such as stab wounds instantly. At 80% activation, he grows black, feathered wings and he can generate massive amounts of electricity. His speed and strength are again increased, and his regenerative abilities and stamina skyrocket, such that he can lose half his torso, including his heart, without any detrimental effects and regenerate it all seconds later. He can only achieve this form, or higher, if he has fed on vampire blood fairly recently, otherwise there is a risk the nanomachines will be unable to generate sufficient power and cause him to collapse. At 100% activation, he turns into a humanoid creature with dark skin, black bat-like wings, and blue markings that cover his entire body. He also generates more electricity than his 80% form and a second blade forms on the other end of his blood scythe (amine only, his 100% form is not currently achieved in any other media). While in Crusnik form, the blood of Methuselah is drawn to him and goes directly into his body without using his fangs. In the manga it is revealed that the nanomachines also have the ability to activate themselves in situations where Abel is injured. Twice the nanomachines activate themselves; the first occasion is a considerable length of time after Abel is badly wounded during his initial fight with Brother Petros. When this occurs, Abel goes off by himself in an attempt to suppress the activation; only tell-tale signs of the transformation are seen in this case (his eyes begin to change) before he succeeds. The second time is during his second encounter with Pedros. This time, Petros compounds Abel's earlier injury with another, and Abel loses consciousness. The nanomachines respond by activating to 80% and regenerating his wounds, as well as driving him into a maniacal bloodlust. In addition, the nanomachines appear to have at least some level of intelligence; Abel refers to himself as "we" during his aforementioned bloodlust, reverting to the singular "I" only after snapping out of his rampage (manga only).
In the novels, he vows never to fuse to 100%, because it sent Cain into insanity. Also, Cain takes the nanomachines of Lilith, so Abel cannot be revived using her nanomachines. Crusniks are literally immortal, but it takes long for their bodies to fully repair when their heads are severed. If, in that injured state, their nanomachines are taken, they cannot regenerate. In the manga, his scythe can produce a blade on both ends no matter what percentage of nanomachines he has active.
