Doom

Doom is the eldest son of Innocent Zero. He is also the strongest member of the Devil's Quintuplets.

Due to his actions and role, he is a major antagonist in the Eclipse Arc.

Appearance
Doom is a very tall man with long unkempt and spiky white hair decorated with small hair ties at every tip, it increases in length whenever he increases his strength. He also wears a visor that covers his upper face. Underneath his visor are eyes lacking pupils having been blind in both since birth.

Personality
Doom is in constant search for a worthy opponent and greatly enjoys his battles. He, however, claims to not enjoy picking on the weak. Doom also shows himself to be a coolheaded and calm man compared to his brothers' with their personalities and eccentricities, in a similar manner to Mash. According to Cell War, Doom is wary towards his younger brother, Famin due to his insanity and extreme violent impulses, however, Doom still maintains his calmness as he regularly bashes off Famin's threats and keeps him in line with equal amount of violence. When in combat, Doom is utterly ruthless towards his opponents.

Equipment
Caladbolg (カラドボルグ, Karadoborugu): An incredibly large sword wielded by Doom. It has a crude blade and an unusual handle. It's named after the sword of Fergus mac Róich from the real-world irish mythology.

Master Cane: According to Domina, Doom was chosen by one of the thirteen Master Canes. Doom's Master Cane enables him to use his magic power to enhance his physical capabilities, effectively allowing Doom to surpass his human limits.

Magic and Abilities
Mirage (ミラージュ, Mirāju): Doom's personal magic. It allows him to mirror his movements and to create mirror duplicates of himself, to attack his enemies off guard. It seems, that he rarely uses it, as his Master Cane's power and his own natural strength normally suffice to take down his opponents. Mash managed to force Doom to use the latter's magic during their battle.


 * Mirage Illusion (ミラージュ イリュージョン, Mirāju Iryūjon): Doom creates four mirrors that conjure duplicates of himself.


 * Mirage Secondth: Collideoscopes (ミラージュ・セコンズ 「カロイルスーコーブズ」, Mirāju Sekonzu「Karoirushīkōbuzu」): The Secondth of Doom's Mirage. Doom creates a gigantic kaleidoscope that conjures countless duplicates of Caladbolg, which he swings at his opponent from all sides.


 * Mirage Acrobatics (ミラージュ アクロバティクス, Mirāju Akurobatikusu): Using his mirrors, Doom multiplies his sword Caladbolg into four copies and launches them at his opponent.

Immeasurable Magic Power: As the eldest of the Devil's Quintuplets, Doom is stated to possess an incredible amount of magic power. Doom in his default form, while not possessing a higher amount of magic power than Domina, is still said to be stronger overall speaking. Doom's magic power increased after his first encounter with Mash, as noted by Cell War. Doom is normally only using up to 50% of his magic power if he unleashes more of it, his form and strength increases further. The more power Doom unleashes, the longer his hair gets. His muscles also increase in size, most likely due to his Master Cane converting his magic power into physical strength. According to Doom, Mash is the first person since his father, that managed to force him into using his full strength.

Swordsmanship: Doom is a powerful swordsman. His swordsmanship, combined with his strength and speed allows him to defeat opponents without using his personal magic and he is able to create powerful air slashes to cut through his targets from distance. He was even able to destroy Renatus Revol's Thirds with his skill and strength alone.

Immense Strength and Speed: Doom possesses incredible strength and speed, even with just a small portion of his power. He is able to wield his massive sword with ease and even perform swift attacks with it. His strength and speed at 50% is great enough to match Mash's (albeit with his wrist weights on). Similar to Mash, Doom is capable of great muscle control, as shown when he prevented Famin from cutting him with a card by clenching his muscles. His strength is achieved through converting his magic power into raw physical strength through his Master Cane.

Immense Durability: Doom is incredibly durable, being capable of taking immensely powerful strikes from Mash without receiving any visible damage.

Regeneration: Doom and his brothers got their hearts replaced by demonic ones, that can use magical energy to heal bodily injuries. They cannot be killed by conventional means, as they can regenerate at an extreme speed, as long as they have enough magic power, which will not run out due to a dose of Innocent Zero's powerful blood in their veins.

Summon
Freyja (, Fureiya; Kanji meaning "God of Bounty"): As a triple-liner Doom possesses the ability to call upon a god's strength from within his wand. He calls forth the god of bounty, Freyja. Upon activation, Freyja creates two mirrors with an intricate design around Doom.


 * Mirage Thirds: Hundred Avatar Mirage (ミラージュ サーズ「ミラージュアバターハンドレッド」, Mirāju Sāzu「Mirāju Abatā Handoreddo」, Lit. Mirage Avatar Hundred): The Thirds of Doom's Mirage. Unlike with other Thirds, Doom doesn't manifest a god but instead multiplies himself hundredfold. According to him, every duplicate is as strong as the original.

Relationships

 * Innocent Zero: Doom's Father, he respects his father to the point he stopped himself from finishing off Mashle when told to withdraw.
 * Famin: Younger Brother, second son of Innocent Zero and second after Doom himself.
 * Epidem: Younger Brother, third son of Innocent Zero.
