Doom is a very tall and muscular man, with a long, unkempt, spiky white mane adorned with small hair ties at each end, the length of which increases each time his strength increases.

He also wears a visor that covers the upper part of his face, and beneath the visor, pupil-less eyes are visible because he has been blind in both eyes since birth. Like his parents and siblings, he has two clock-shaped lines protruding from his eyelids and pointing upwards.

Doom constantly seeks a worthy opponent and greatly enjoys his battles, but claims he dislikes attacking the weak. However, Doom also appears calm and collected compared to his brothers, whose personalities and eccentricities are quite pronounced, much like Mash Burnedead.

In combat, Doom is absolutely ruthless with his opponents.

Equipment
Caladbolg: An incredibly large sword wielded by Doom. It has a rough blade and an unusual hilt. It can launch powerful aerial attacks from a distance thanks to Doom's incredible strength. It is named after the sword of Fergus mac Róich from Irish mythology.

Master Staff: According to Domina Blowelive, Doom was chosen by one of the thirteen Master Staffs. Doom's Master Staff allows him to use his magical power to enhance his physical abilities, enabling him to surpass his human limitations. He can focus the force of his power into specific muscles of his body. He apparently stores it within his sword Caladbolg, similar to Abyss Razor, who stores his wand within the hilt of his sword.

Magic and abilities
Mirage: Doom's personal magic. It allows him to reflect his movements to create duplicates of himself and attack his enemies by surprise. He apparently rarely uses it, as the power of his Master Staff, his swordsmanship, and his immense natural strength and speed are usually enough to defeat his opponents. Mash Burnedead managed to force Doom to use his magic during their battle.

Mirage Illusion: Doom creates four mirrors that conjure duplicates of himself. The mirrors can create more duplicates if the previous ones disappear.
Collideoscopes
The second Doom game, Collideoscopes.
Mirage Second: The second Doom Mirage. Doom creates a gigantic kaleidoscope that summons countless duplicates of Caladbolg, which he launches at his opponent from all sides.
Mirage Acrobatics: Using his mirrors, Doom multiplies his sword Caladbolg into four copies and throws them at his opponent.

Immense Magical Power: As the eldest of the Devil Quintuplets, Doom is said to possess a terrifying amount of magical power. In his default form, Doom doesn't possess more magical power than Domina Blowelive, but he is generally considered stronger. Doom's magical power increased after his first encounter with Mash, as mentioned in Cell War. Doom typically only uses up to 50% of his magical power. If he releases more of it, his form and strength increase even further. The more power Doom releases, the longer his hair grows. His muscles also increase in size, most likely due to his Master Staff converting his magical power into physical strength. According to Doom, Mash is the first person since his father who has managed to force him to use his full power.

Master swordsman: Doom is an extremely skilled and powerful swordsman, probably the best in the world even without using magic in his swordsmanship. His swordsmanship, combined with his strength and speed, allows him to defeat his opponents without using his magic.

Master Swordsman: Doom is an exceptionally skilled and powerful swordsman, arguably the best in the world even without using magic in his swordsmanship. His swordsmanship, combined with his strength and speed, allows him to defeat his opponents without using his personal magic, and he is capable of creating powerful aerial slashes strong enough to pierce through his targets at a distance. He was even able to destroy Renatus Revol's Thirds and overcome the latter's regenerative abilities using only his skill.

Immense Strength and Speed: Doom possesses colossal physical strength and speed, even with only a small fraction of his power. He can wield his enormous sword with ease and even execute rapid attacks with it. His strength and speed at 50% are great enough to match Mash's (albeit with wrist weights). Like Mash, Doom is capable of great muscular control, as demonstrated when he prevented Famin from cutting him with a card by tensing his muscles. His strength is achieved by converting his magical power into pure physical strength using his Master Staff.
Immense durability: Doom is extremely durable, being able to withstand immensely powerful blows from Mash without suffering any visible damage.

Regeneration: Doom and his brothers received demonic heart transplants that allow them to use magical energy to heal wounds. They cannot be killed by conventional means, as they regenerate at an extreme rate as long as they have sufficient magical power, which is inexhaustible thanks to the powerful blood of Innocent Zero that runs through their veins.

Convene
Invocation of Freyja: As a being of three lines, Doom possesses the ability to summon the power of a god from his wand. He summons the goddess of abundance, Freyja. Upon activation, Freyja creates two intricately designed mirrors around Doom. Strange cosmic creatures rest before the mirrors.

Mirage Thirds: Hundred Avatar Mirage: Doom's Thirds. Unlike other Thirds, Doom doesn't manifest a god, but rather multiplies himself a hundredfold. According to him, each duplicate is as strong as the original.

Innocent Zero:
Innocent Zero is Doom's father, and Doom respects Innocent Zero to the point that he refrained from killing Mash Burnedead when he was told to stand down.

Famin:
Famin is Doom's second younger brother.

According to Cell War, Doom distrusts Famin because of his madness and extreme violent impulses, but he still remains calm, as he usually dismisses Famin's threats and keeps him at bay with equal force.

Epidem:
Epidem is Doom's third younger brother.

Delisaster:
Delisaster is Doom's fourth younger brother.

Dominate Blowelive:
Domina is Doom's fifth younger brother.

Mash Burnedead:
Mash is Doom's sixth and youngest brother, whom he finds really interesting, and was very impressed when Mash managed to force him to use 50% of his personal strength and magic during their first fight.

Seeing that Mash was holding back, Doom was eager to see him and face him at his full potential. During their second fight, Doom felt grateful to have met Mash at the climactic moment of the battle.

Doom's calmness and incredible confidence are very similar to those of Mash Burnedead.
Doom is the tallest of the Devil's Quintuplets.
Like his brothers, Doom might have a predilection for sweets, as he expressed interest in making pancakes after hearing Mash's dreams of becoming a pastry chef.
