Doma's powers and abilities
Overall Abilities: As the holder of Upper Rank Two, Doma is an extremely powerful demon, being the second highest ranking member in the Twelve Kizuki and the third strongest demon in existence. His combination of combat skill and his powerful cryokinetic Blood Demon Art in battle is powerful enough to overwhelm and defeat the Insect Hashira, Shinobu Kocho, without any difficulty, and he is also noted to have defeated Kanae Kocho, the late Flower Hashira, in the past. Afterwards, Doma could take on both Inosuke and Kanao, who were on par with the Hashira, simultaneously without much effort either.
According to Doma, Akaza, who holds the rank of Upper Three, would have no chance in defeating him in battle.[22] Moreover, Doma was able to surpass Akaza in a shorter period of time, showcasing the immense power gap between the two demons. As further credence to Doma's immense power, he rarely fights seriously and instead adopts a casual and carefree attitude even in life-and-death situations against the most powerful Demon Slayers, only ever becoming serious when his life is in serious danger, such as when the deadly effects of Shinobu's poisons became apparent.
"You don't feel anything, do you?"
Apathy: Doma is clinically apathetic, being completely incapable of feeling human emotion. Doma covers his emotionlessness with a carefree and friendly facade that was able to trick all but the most keen observers. Kanao is the only human that was able to discern his true disposition using her superhuman eyesight, and concluded that Doma merely acts like he shows emotions in hopes that one day he would actually be able to feel human emotions himself, a concept which he admitted seemed alien to him. Even when he was a child, Doma possessed little to no emotion, as shown when his mother ruthlessly murdered his father and then proceeded to kill herself in front of Doma, he was neither shocked nor petrified, rather oddly, he felt annoyed as their blood made the room stuffy.
This inability to feel emotions has unexpectedly become an advantage for Doma, as this allows him to calmly process, understand and analyze any situation he is faced with without being hampered by emotions, allowing him to easily come up with any solution for any adversary. Although, after his death, he seemed to have developed feelings for Shinobu Kocho, making it the first time he actually shows true emotion.
Biological Absorption: Doma briefly displayed the ability to absorb human bodies through physical contact, shown when he completely broke down and assimilated Shinobu's body within few seconds of killing her. He mostly uses this ability as a faster alternative of consuming humans during battle.
Extrasensory Perception: Doma possesses extraordinary sensory abilities which allow him to detect things outside the normal range of perception, as shown when he could perceive attacks even from places he is not looking at, allowing him to nullify the effectiveness of sneak attacks. Later, Doma was capable of detecting Akaza's transformation into a demon immune to decapitation by Nichirin Swords despite being extremely far away from him.
Immense Durability: As an Upper Rank demon who has assimilated a huge amount of Muzan's blood, Doma has an exceptionally durable body. This is shown when Kanao had difficultly slicing Doma's neck even when his body was unable to regenerate properly. Kanao only succeeded in decapitating the Upper Rank when Inosuke used his swords to push her blade through Doma's neck.
Doma blitzes Shinobu, one of the fastest Hashira.
Immense Speed & Reflexes: Doma possesses inhuman movement speed and reflexes, being able to move so fast he appears to teleport. Due to their rankings, it is strongly suggested that Doma is faster than Akaza, who was able to keep up with a Marked Giyu while holding back, and Gyutaro who was able to keep up with and overpower Tengen, the fastest runner among this generation's Hashira. He first displayed his immense speed during the Upper Rank meeting, where he appeared to teleport to Gyokko, which caught him off guard. Later, when Akaza appeared behind him and destroyed his head, Doma claimed that he could've easily evaded it if he wanted to, but didn't do so on purpose as he wanted to get along with him.
His imperceptible speed was further testified when she sliced a woman to pieces after Shinobu, the fastest Hashira Doma has met, brought her away from his attack range, taking the Insect Hashira a while to register the attack. Moreover, Doma was shown to be able to keep up with Shinobu's imperceptible speed for the majority of the fight. More impressively, Doma was able to deliver a deep cut to Shinobu before she could even react, effectively blitzing her. Against Kanao, a Hashira-level Demon Slayer, Doma was able to easily dodge her Crimson Hanagoromo technique while still busy absorbing Shinobu, and later managed to move so fast he appeared to teleport behind her, nearly decapitating the Demon Slayer's head.
Later on in the fight, Doma managed to completely blitz Kanao, running up to her from a considerably far distance, stealing her Nichirin katana while she was still gripping onto it, and returning to his original spot so fast that Kanao, despite possessing superhuman vision, couldn't react to, let alone perceive the Upper Rank's movements, even taking several seconds to comprehend and realize what just happened. Similarly, Doma blitzed Inosuke, this time, stealing his mask without he and Kanao realizing it until several seconds later. Due to how casual Doma was when he performed the aforementioned feats, it is implied that Doma could've instantly blitzed and killed both Kanao and Inosuke had he taken the fight more seriously.
Immense Regeneration: As an Upper Rank demon, Doma possesses one of the most advanced and powerful regenerative healing factors in existence. When Akaza punched off both his lower jaw and his upper head and he instantly healed with ease, even considering the fatal attack to be a friendly gesture. Doma also took mere seconds to recover from Shinobu's onslaught of fatal Wisteria poison attacks and from a deep slash in his abdomen which caused his guts to spill out. Even when Doma absorbed Shinobu's body and ingested over 37 kilograms worth of poison, approximately 700 times[23] more than the lethal amount needed to kill an average demon, it still took a considerable amount of time before it began to have any adverse effect on him.
Reactive Adaptation: During his battle against Shinobu, he is able to break down and render all of the various poison mixtures Shinobu injected into him useless, immediately developing antibodies to her poison without much trouble. Shinobu herself was shocked at how fast Doma built a resistance to her normally fatal poison.
Doma correctly deducing Kanao's abilities and developing a strategy mid-fight.
Keen Intellect: Doma is exceptionally intelligent, which he displayed on multiple occasions. While in a fast-paced brawl with Kanao, he was able to process and deduce her abilities, surmising that it was her superhuman eyesight that allowed her to parry and dodge his ice attacks and immediately develop a strategy to counter it. In another instance, when he left Kanao and Inosuke to fight his ice clones, he construed that Inosuke had an acute sense of touch just by observing his behavior when near his ice techniques.
It is also implied that Doma was able to trick and deceive all of his followers, allowing him to kill and eat them. He was able to keep this up for over a century with almost complete infallibility. Doma also possesses incredible memory, being able to remember even the most insignificant details from back when he was human, which was over a century ago.
Unlimited Stamina & Endurance: Doma possesses absolute and infinite stamina and vitality, never tiring and always remaining in optimal physical and mental condition all the time as well as being able to endure waves of onslaught as if it were nothing. He showed almost complete immunity to being repeatedly violently attacked by his fellow Upper Rank, Akaza, having his eyes slashed out by Inosuke, being repeatedly poisoned and stabbed by Shinobu, having his stomach slashed open by Kanao and inflicting various forms of extreme self-harm to himself. Doma never once expressed the slightest bit of pain, discomfort and panic at being wounded so grievously, having been able to nonchalantly and calmly continue fighting, talking or doing whatever else he is doing as if nothing is happening.
Fighting Style
Tessenjutsu: Doma is incredibly skilled in Tessenjutsu as shown during his battles against the Demon Slayers. It is implied that his skill in this martial arts surpasses Akaza's bare-fisted combat prowess due to their rankings. Doma showcased his skill in dual wielding his Japanese war fans against Kanao and Inosuke, where he could easily fend off both combatants, displaying his ability in using his fans for both attacking and defending during high-speed battles, parrying and delivering attacks that overwhelmed the Demon Slayers.
With his exceptional proficiency in Tessenjutsu, Doma could make use of techniques that require him to perform eight to nine fan attacks in the blink of an eye and generate huge gusts of air with them. Furthermore, Doma's Tessenjutsu incorporates his cryokinetic Blood Demon Art which enhances its range and lethality, making his fighting style a great blend of offense and defense.
Blood Demon Art
Doma's technique rapidly freezing the surroundings.
Cryokinesis: Doma's Blood Demon Art grants him extremely powerful cryokinesis. He can generate ice and frost from his flesh and blood and can spawn it anywhere in his vicinity, as well as manipulating it at will, allowing him to unleash incredibly potent ice techniques. Additionally, the ice created from his Blood Demon Art is extremely lethal to those that inhale it, causing the cells of the victim's lungs to die and rendering them unable to breathe very quickly. His ice and frost has also been noted to be extremely cold, as shown when the air around Doma's frost was cold enough to make Shinobu's lungs feel as if they were about to burst and nearly freeze Kanao's body and surroundings just by coming into contact with it.[24][25]
Doma is incredibly proficient in his Blood Demon Art, being capable of creating constructs out of the ice he generates such as frost lotuses, stalagmites, clouds of icy air and even miniature ice clones of himself capable of unleashing the same techniques as him. He has also shown the ability to use the ice he creates as extra appendages, as seen when he created ice vines to hold himself up the ceiling while he uses his arms to hug Shinobu. In combat, Doma usually incorporates his cryokinetic abilities with his Tessenjutsu, enhancing his fan attacks with ice and frost. Doma prefers to use his Blood Demon Art to create frost lotuses and crystal-like shards made of ice.

He has shown to be capable of creating up to six clones of himself at once,[36] all possessing roughly the same skill and proficiency as Doma himself in addition to being fully capable of using any of his techniques, albeit not to the same caliber as him.[37] Furthermore, these clones are able to record any information it gathers during battle and relay it to Doma, allowing him to better fight his opponents.[38] However, one drawback to this technique is that the clones require concentration in order to maintain their functionality, as seen when they disappeared when Shinobu's poison started to take effect on Doma.[39]
Rime — Water Lily Bodhisattva (霧む氷ひょう・睡すい蓮れん菩ぼ薩さつ Muhyō - Suiren Bosatsu?)[40] - Doma creates an enormous Bodhisattva statue surrounded by lotuses made of ice. Its most notable trait is its ability to generate huge gusts of Doma's deadly ice from its mouth and deliver powerful physical attacks using its large arms.[41][42] It is also able to grab targets using its hands.[43]
