Mamon

Mamon is one of the six Angels of Death and owns a pharmaceutical company that was in charge of making the "vampire vaccine".

Appearance
Mamon has messy shoulder length dark hair, pale skin, and glasses. He normally wears a black blazer, gray collared shirt, black tie, and black pants. He has thick eyebrows the same shade as his hair.

Personality
Mamon is presumably a genius scientist and shrewd business man, having taken ownership of a pharmaceutical company in his 20s. However, Mamon is a depraved and ammoral vampire. In particular, he harbors extreme envy against people in relationships and enjoys tormenting them. He has a perverted mind, his ultimate desire is to get all the women in the country. As a vampire, he used his power to commit many crimes against women and particularly women already in relationships.

Mamon is easily irritated if someone destroys even a part of his work or voices dissent. He believes in a strict hierarchy of power where the lesser vampires should not voice discontent with God.

Synopsis
In the past, Mamon was a civilian who tried to hook up with multiple women that he finds attractive. However, no matter how much attempts he tries, he always ultimately failed in the end. Due to his many attempts to flirting with women who are already in relationships, people began to spread rumors about him amongst the public, and soon, he was infamously known to all about his obsessive and possessive tendency.

Mamon is present at an Angel of Death meeting where he watches as Ash kills Sahan, having been fooled by Ash's acting skills. After Ash leaves to confront the Pureblood, Mamon expresses his confusion as to why Ayeong is so antsy to perform such a task and why the Angels are not working as a group. Another Angel replies that God ordered them to go after the Pureblood one by one. He also notes that while all the other Angels had a clearly defined role in the organization, Ayeong did not and felt that she needed to prove she belonged.

Following Ayeong's desertion, Mamon is furious that she had destroyed a bottle of the medicine he had worked 5 years to create. However, he is quickly forced to calm himself as God arrives to the meeting. He berates some of the mixed blood vampires for trying to seek greater power and watches as God cruelly and brutally kills them. Mamon confirms with God that the medicine is ready to be shipped. Mamon then declares that he will go after the Pureblood next. Baal questions this, but Mamon assures him that he has a plan and that the risk is worth the reward.

Some time later, Mamon returns to the pharmaceutical production facility with Yohan to demonstrate the effectiveness of his vaccine. After confirming its effectiveness and beginning delivery, he summons a kidnapped couple. There he psychologically torments them before revealing the true purpose of the vaccine: The vaccine doesn't prevent people from turning into a vampire, it actually gradually turns them into one, and the medicine also makes the victim more susceptible to hypnosis. He then torments the couple further before taking them away to an unknown fate. He then relaxes with his harem of vampire women. He converses with them, sharing that the medicine will turn human into vampire, and amplify the strength of people who are already vampires.

Later, Mamon screens another batch of kidnapped couples and unknowingly selects a disguised Euntae Hwang and Hayan Park. As he begins his psychological torture, he reveals the truth about the "vaccine" to them. Hayan eventually punches Mamon, which knocks him out. When Mamon comes to, he realizes that he is facing the Pureblooded Vampire. Mamon ingests a large quantity of the medicine and transforms into a gigantic muscular vampire. This, however, does not give him enough strength to fight Hayan, who easily knocks him back. The effects of the medicine start wearing off and Hayan attempts to hypnotize Mamon, but Mamon is protected by God.

Later, as God flees the pharmaceutical company, he kills Mamon, having no use for him anymore.

Powers and Abilities
Mamon's abilities as an Angel of Death are unknown as he died before adequately showing off his abilities. Mamon, however, is presumably stronger than Ayeong, Sahan, or Lucian as he outranked them in the Angels hierarchy.


 * Medically Enhanced Strength: Thanks to his medicine, Mamon is able to achieve a monstrous appearance and enhanced strength, though it still pales in comparison to a Pureblood's strength.


 * Genius Intellect: Becoming the CEO of a pharmaceutical company at age 25, Mamon appears to be a very smart man. He used his medicinal knowledge to invent a fake vaccine that will gradually turn people into vampires without them being aware of it, and also make the victims more susceptible to hypnosis.

Weaknesses

 * Lack of Durability: Mamon, in his untransformed state, lacked the durability and endurance of his fellow Angels. He was easily knocked unconscious for a period of time after one uppercut to the jaw from Hayan. It should be noted that, at the time of confrontation, Hayan had recovered all her memories and could fully tap into her vast reserves of strength. His medically enhanced transformation did not have any durability either, as Mamon was quickly beaten back and de-transformed within moments after transforming.
 * Sociopathy: Mamon's desire to torment couples was so great that it can cause him to become careless. Hayan's and Euntae's over the top acting caught his attention and he chose them to torture in a private setting without a thorough background check. This left him vulnerable to their ambush.
