Power

Power was a Blood Fiend and a Public Safety Devil Hunter who is part of Makima's special squad. She was a deuteragonist of the Public Safety Saga. Power possesses the corpse of an unknown woman or girl with long hair. Her hair color varies from blonde to pink in manga illustrations and appears strawberry blonde in the anime. As a fiend, she has red and yellow eyes that form a cross pattern, sharp teeth with defined fangs, and light red horns protruding from the top of her head. If Power accumulates too much blood, her horns become larger and more curved, and she can sprout additional pairs of horns from the sides of her head. Power usually wears the standard dress shirt, tie, and slacks required of Public Safety Demon Hunters. Normally, she wears breast pads to increase the size of her bust.

 

She almost always wears her jacket hanging halfway off her body giving her an untidy, half-dressed appearance. In her Blood Devil form, she appears as a tall humanoid with four arms and a mostly pale skinned body. Her head has a pointed appearance with a red color, sharp teeth, and two circular eyes with cross-like pupils. She also has long horns, resembling how her fiend form looked with too much blood, and longer hair in this form. Her chest has an open rib cage showing a chest cavity full of intestines up to her neck. Her arms have red coloration from hand to elbow. She has four-fingered hands and large claws. Her legs have the same red coloration from the mid-thigh down, ending in heel-like feet and she has a cat-like tail. Power is childish, greedy, and almost entirely self-motivated. She tends to fight as if she has something to gain and is certain of her victory, and has no problems with running away from a fight where she is outmatched. She feels the need to boast her superiority over her fellow Devil Hunters due to her status as a fiend. She has no loyalty to humans or devils, openly admitting that she will join whichever is the winning side. Power also enjoys the thrill of a fight and enjoys showing off her strength and proving her own superiority. When she was in front of an army of zombies she got excited and told Denji to watch carefully how she single handedly defeats all of them. She is highly egoistical and often claims she is capable of doing things she cannot actually do, only to abandon them halfway through when the situation turns sour for her. She frequently deflects the consequences of her actions to those around her. 

Abilities

In her original form as a devil, Power claimed to be greatly feared to the point where other devils would flee from her scent, though this is quite possibly just boasting. As a Devil, Power possesses all of the standard devil abilities, such the ability to make contracts with humans for a price, restoring her health by consuming blood, take over a dead human body and their consciousness, becoming a fiend, and reviving in Hell after being killed.

Right now, Power has only one contract, being with Denji. In exchange for promising to find and befriend the reincarnated Blood Devil, Power gave Denji her blood. Denji used her blood to create a blood chainsaw and disturb Makima's regeneration.
Physical Abilities

    Enhanced Speed: Power is a quick fighter, able to land an attack on Denji when she betrayed him while evading Denji's own swing. She was able to disappear from the Katana Man's sight as he gunned down the devil hunters before landing an uppercut that he couldn't block.

    Enhanced Smell: Power has a keen sense of smell, recognizing the scent of blood from a distance, while Denji was oblivious, and following it in order to track down the Sea Cucumber Devil.

Devil Powers

    Blood Manipulation: Power can freely manipulate the blood in her body to form weapons. She can also manipulate other people's blood through direct contact and is able to prevent them from bleeding out though she acknowledges that it is difficult. Power can also distort her target's regenerative abilities by mixing her own blood.
        Blood Hammer: Power can create an enormous hammer out of her own blood which she uses to crush her opponents. She can also make smaller handheld versions.
        Blood Spear: Power can create a spear out of her own blood and uses it to stab at her target. By placing her blood in bottles and hiding them in the area as traps she can make spears suddenly appear from the environment to take her opponent off-guard.
            Thousand Tera Blood Rain: In her Full Devil form, Power can generate thousands of blood swords and spears from the blood surrounding herself, levitate and throw them to her enemies. She can use this technique several times. This technique is strong enough to halt Makima for a couple of seconds.
        Blood Transfer: Through a contract, Power can transfer her blood and life energy to someone, similar to Pochita's ability to assimilate Denji's body. It was enough to completely heal the critically damaged Chainsaw Man´s body.

    Blood Empowerment: As a fiend, Power is able to restore her health by consuming blood. Also as the Blood Devil, her regenerative powers are in higher level than other devils. When Power drinks too much blood or drinks blood from stronger devil then her power drastically increases. It is shown that she sprouts additional horns from her head after drinking too much blood. In this state a single punch from Power has enough force to launch Denji into the ceiling. She can regenerate herself from small amounts of blood even after her death by consuming the blood of the stronger devil. After the defeat of the Chainsaw Man in the hands of Makima, Pochita exploited this ability by letting the blood of her inside the Denji's body to consume itself. After drinking blood of the Chainsaw Man, Power revived as a devil from a little amount of blood Denji have consumed. Her speed, strength, durability and blood manipulation abilities have been increased dramatically. After transformation, she is also able to resist Makima's domination powers.
