Denji

Denji is both brash and naïve as a result of being unable to have a formal education and socialize due to living in severe poverty, making him generally crass and vulgar. His personality comes off as rude and harsh in an almost childish way. However, he has a good sense of empathy towards other people, willing to save those in danger as much as he could, showing he is a kind-hearted person despite his shortcomings. While Denji doesn't necessarily possess the highest intelligence, he is capable of clever ideas to take down Devils, such as lighting himself on fire and using the light emitted to weaken Santa Claus enough to kill her. After becoming a Public Safety Devil Hunter and fulfilling his basic needs, Denji is unsure of what he wants in life. Many of Denji's said basic needs were fueled by sexual desire, going so far as to accept dangerous missions in exchange for some form of sexual gratification. One such case was touching Power's breasts in exchange for rescuing her cat, however, he later realized and laments that the satisfaction from such intimate acts is fleeting. Denji also harbors a fear that his seeming lack of empathy and attachment after his transformation is a sign that he is losing his sense of humanity. While transformed into his Hybrid form, Denji becomes extremely ruthless, aggressive, bloodthirsty and sadistic, releasing his most deranged side while facing other Devils, to the point of enjoying killing them. He also displays a twisted and sarcastic sense of humor. The first time he transformed into his Hybrid form he found it amusing that he could pay off his debt by killing all the Yakuza members who were turned into zombies due to the power of the Zombie Devil. While facing the Eternity Devil he says that "its blood tastes like rat but drinking it while watching a son of a bitch suffering and feeling terrified makes it taste as delicious as a strawberry jam", and considers himself a genius for creating a "perpetual motion machine" worthy enough of a Nobel Prize. Later, when the Spear Hybrid has Denji pinned down, he bisects both himself and the hybrid behind him before crawling over to him, cutting his head off, and thanking him for the food while holding said head. As the story progresses, it becomes more evident that Denji is emotionally damaged, and desperate to feel love and be loved by someone. He clings to Makima as a coping mechanism, even going as far as stating that his wish was to just be a mindless dog, so he would not feel hurt from losing the things and people he loved. This backfired, as watching Power die was enough for him to surrender himself to Makima completely, essentially erasing his personality and mental state. This is still evident when Denji tells Kishibe that he did not set out to kill Makima, but rather become one with her, allowing him to defeat her. Nevertheless, Denji's feelings for Makima persisted unaltered; he continued to declare that he loves her "from the bottom of my heart". Near the end of the first part, as well as at the start of the second part, Denji starts growing more ambitious and lavish in his desires; whilst before he was happy with simply being able to eat jam on toast and feeling a girl's chest, now he desires to have steak for breakfast every day and to have numerous, lustful girlfriends. It's also shown he has grown more arrogant in his Devil-slaying, as he is willing to expose his identity if it means he'd get more attention from girls, despite how disastrous the consequences would be. As such, at the beginning of the second part, Denji's personality seems to have remained relatively stagnant, aimed at openly leaving clues that indicate that he is Chainsaw Man, such as leaving his school I.D. at the scene of his fight with the Cockroach Devil, or directly telling Asa Mitaka that he is Chainsaw Man (to which she thinks he is bluffing). He also reveals himself to be obsessed with money, so much so that he is willing to let others pay to use him as a "chair" for a few yen (although he seems to enjoy it when a woman uses him as a chair) and to sell used cigarettes to the homeless, passing them off as new, just to make money. However, Denji later demonstrates the true motivation behind most of these behaviors, which is to fund his adopted sister's education, thus showing that he has matured following the disastrous consequences of letting Makima groom, abuse, and control him in their relationship, becoming more independent and standing up for himself without allowing others to dictate his behavior. During the date with Asa, Denji becomes flustered and angry with her when she told him that he didn't need to think about anything, possibly reminding him of his relationship with Makima. He further reveals to Asa that the reason he is desperately saving money is to provide Nayuta with a proper education and a comfortable lifestyle, showing that he has acquired a strong sense of responsibility towards others.

Human Form (Pre-Fusion)
Denji is a fair-skinned teenage boy with scruffy blond hair that has strands sticking up and falling messily around his head. He has yellow-brown eyes and bags underneath, resulting in a dazed and tired expression. His teeth are noticeably sharp and angular. Due to malnutrition in his childhood, he has a scrawny and undernourished build with protruding ribs, relatively long-looking, almost lanky legs, and slim wrists, and due to the stress of what he did for a living, he’s often mistaken for being older than he actually is. Before becoming a Hybrid, Denji was missing his right eye and several other non-essential organs, including a testicle and a kidney. He covered his missing eye with an eyepatch. He also wears a loose white tank top, a green jacket and black pants during this time. In a new world where Pochita never existed, Denji retains his eyepatch while wearing the Public Safety Devil Hunter uniform and suit as a Public Safety Devil Hunter working under Nayuta's command.

Physical Prowess
*Enhanced Human Condition: Due to fusing with Pochita, Denji gained superhuman abilities even when not transformed. In his human form, Denji is durable enough to survive being hit by Power with a hammer and getting squeezed by the Bat Devil, despite both individuals possessing immense strength. He is also very strong, capable of decapitating a Fiend with just one swing of his Axe. **Enhanced Endurance: Due to his rough childhood, Denji has developed a high tolerance for pain and stress, being able to still function as a Devil Hunter for the Yakuza despite having multiple of his organs missing at the time. His mental fortitude has allowed him to fight for three days straight while constantly being injured and remaining conscious even after having multiple parts of his body cut or blown off.
