Power

 Warning: This page contains major spoilers for the Chainsaw Man series. Please read at your own risk.

Power (パワー) is a Blood Fiend (の) and a Public Safety Devil Hunter who is part of Makima's special squad.

Appearance
Power has the appearance of a young woman with strawberry blonde hair that reaches down to her mid-back. As a fiend, she has light red horns protruding from the top of her head, red and yellow eyes that form a cross pattern, and sharp teeth with defined fangs.

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.

During Operation: Super-Smart, Power donned a pair of glasses and tied her hair back in a ponytail.

If Power accumulates too much blood her horns became larger and more curved, and she can sprout additional pairs of horns from her head.

In her Blood Devil form, she appears as a tall humanoid with four arms and a mostly white body. Her head has a pointed appearance with a dark color, sharp teeth and two circular eyes with cross-like pupils; she has long ears in this form and long hair. Her chest has an open rib cage showing a chest cavity full of intestines up to her neck. Her arms have dark coloration from hand to elbow. She has three-fingered hands and large claws. Her legs have the same dark coloration from the mid-thigh down, ending in heel-like feet.

Personality
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, as well as having no problems in running away from a fight where she is outmatched. She also feels the need to boast her superiority over her fellow Devil Hunters due to her status as a fiend. She has no loyalty to humanity, openly admitting that she will join the winning side.

Power is often rude, unkempt, and feels as though those around her should clean up after her. She self-admittedly rarely bathes or flushes the toilet and sees humans as being overly sensitive for caring about their hygiene so much.

Power is a compulsive habitual liar; after getting in trouble with Makima for killing a devil when she wasn't supposed to, Power immediately blamed Denji and claimed he told her to kill it, and she blamed Denji for eating all of the emergency food that the team collected even while she had crumbs on her face. When accused of abandoning a fight because she was scared, Power falsely stated that she ran away merely because she was hungry.

She has no problem gossiping and talking about her friends behind their backs; sharing the secret of Aki's shortened lifespan with the Angel Devil.

Power sees no difference between pork, beef and human meat; being willing to eat all of them, even if the meat is disgusting zombie flesh. She hates vegetables, throwing them away when she finds them in her meal. Power is an insatiable glutton, eating all of the stored food that the team needed in order to survive the Eternity Devil's trap and hoarding food for herself at the Division 4's newbie welcoming party.

When asked by Aki about what reward she could want as part of their mission, Power stated that she desired to suck a human's blood until they die. When promised Denji's blood, Power became ecstatic at the prospect.

Though she is extremely selfish, Power was able to experience compassion for the first time towards her pet, after previously only caring about the smell and taste of blood and the feeling of death when she was killing something. This prompted her to act for the sake of another being when her pet Meowy was kidnapped.

Meowy
Despite initially wanting to eat him and taking care of him only so that he could be fattened up to provide a more delicious meal, Power cares deeply for her cat, Meowy. She was willing to sacrifice Denji's life to save him from the Bat Devil. When she thought Meowy to be dead after being eaten by the Bat Devil she became despondent and empathized with Denji before allowing herself to be eaten.

Denji
Power and Denji initially had a rocky relationship, with Power being entirely willing to trick and sacrifice Denji to the Bat Devil for Meowy's sake. However, after Denji saves Power and Meowy, they begin living together at Aki Hayakawa's home and develop a more amicable relationship. They often bicker and become annoyed with one another, as well as cause trouble for Aki as a pair. Power eventually develops strong affection for Denji, even going so far as to deny Makima's wishes and put her own life on the line to keep him safe. Power considers Denji to be her very first friend, and so values him highly.

Aki Hayakawa
Power takes up residence at Aki's home after she joins Public Safety. Aki frequently winds up being annoyed by Power, and she seems to enjoy needling him. Despite this, she does seem to care for Aki as time goes on. The two might be described as developing a similar relationship to a disgruntled elder brother and bratty little sister, with Power constantly causing trouble that Aki has to deal with.

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 but this is likely just a boast from Power.

Physical Abilities
Enhanced Speed: Power is a quick fighter, able to land an attack Denji as they turned on each other while evading his 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.

Supernatural Abilities
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 Consumption: As a fiend, Power is able to restore her health by consuming blood. As the Blood Devil, 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.
 * Power Enhancement: 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. 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 able to resist Makima's control abilities.

Contract Creation: As a Devil, the Blood Devil should be capable of creating contracts with humans. 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.

Revival: As a Devil, the Blood Devil should revive in Hell after being killed effectively making her immortal.

Skillset
Acting Skills: Power is an amateur actress, capable of faking her death by lying on the ground in order to fool Quanxi. She is able to fool Makima to believe that she betrayed Denji while fighting against her and her controlled victims.
