Denji can be seen in different appearances throughout the series
Human Form (Pre-Fusion):
Denji has blond and scruffy hair with a thin figure after his state of starvation for several years. His teeth are noticeably angular and sharp. He has a scrawny build with protruding ribs due to malnutrition in childhood.
Before becoming a hybrid, Denji was missing his right eye and several other non-essential organs. He wore an eyepatch to mask the sight of his missing eye. During this time, he also wears a loose white tank top, a green jacket, and black pants.
Human Form (Post-Fusion):
As a result of the contract, Denji’s heart is fused with Pochita’s, a chainsaw cord forms between his ribs, and he regains the organs that he lost. His hair becomes orange in color which is messy in appearance, his eyes become lifeless with light-brown pupils, and cringy teeth. In chapter 1 after his merger with Pochita, a chainsaw also appears in his chest.
In his human form, Denji is seen wearing black trousers, a necktie, and a rolled-up shirt. In the public safety division bureau, the shirt is more black, agents like Aki wear a jacket or a blazer.
Denji’s Hybrid form was seen the first time when he had his fight with Zombie Devil.
Like a classic chainsaw action, Denji pulls the cord attached to his chest, chainsaw appears from his arms and forehead. His head has a striking resemblance to that of the base of a chainsaw. His mouth has razor-sharp teeth with a face orange in color and a blade-like tongue, seen in chapter 1.
After Denji’s transformation to the full devil, his intestines bust out from his gut and wraps his neck. In his devil form, his body is more muscular and is covered with plates of armor with 4 chainsaws in the form of his arms.
His resemblance completely changes from the hybrid form with spikes protruding out from the back of his head and his legs are replaced by large claws in this devil form, as seen in chapter 83.
He has simple dreams to live a life like a normal human being. He is childish, uneducated, and raw. He wants to find love, eat meals like breakfast and dinner and he also has intimacy with a woman. For the money, he could go to any lengths as seen in chapter 1 where he ate a cigarette for 100 yen.
Denji is easily attracted by women, Himeno vomited while they were kissing but still, he got attracted to her, seen in chapter 21, and he was fooled by Reze too in chapter 51.
Despite all these facts, he is caring, after getting attached to someone. He treats Aki and Power as a family but due to lack of emotion, he never cried when poor things happened to Aki and Power.
While fighting Denji is ruthless and violent and is careless when it comes to safety. As seen in chapter 19, he ran his chainsaw for 3 days nonstop against Eternity Devil but he also fought back.
Strength and Abilities
This ability allows Denji to regenerate and reattach his limbs and fatal wounds. It is seen in chapter 30 during his training with Kishibe he was being shot, stabbed in the head and he even died more than 20 times but still came back to life.
Blood is the primary element when it comes to regeneration.
He only has to drink the blood of a devil or a human to transform himself into a hybrid form.
He can transform into a bloodthirsty Chainsaw Devil by pulling on a cord from his chest. Since he needs blood to use his abilities, if he doesn’t have enough he can’t fully transform, however, he can manifest shorter and weaker chainsaws. As a result of his contract with Pochita, he has this ability. Pochita became Denji’s heart in exchange for living a “normal life.”
A contract can involve the human sacrificing something precious to the devil in exchange for a small amount of his power. He has 2 contracts as of now. One from power and another one from Pochita. He accepted Pochita’s contract and got merged with him and got chainsaw devil’s abilities by becoming a hybrid. Denji accepted Power’s contract to find a blood fiend and make him his friend.
