Pochita

Pochita (ポチタ) is the Chainsaw Devil (チェンソーの悪魔, Chensō no akuma) who embodies the fear of chainsaws.

Appearance
Pochita appears to be a small red canine with a chainsaw like appendage protruding from the center of his head. Handles emerge from his body allowing him to be wielding like a chainsaw and his short tail is in the shape of a chainsaw's pull cord. His true devil form is of a large, humanoid devil with four arms and a chainsaw protruding from each, with another chainsaw coming from the front of his head similar to Denji's hybrid form.

Personality
Unlike most devils Pochita communicated solely through barks and whines like an actual dog. However, after fusing with Denji, he is able to communicate with him in his mind. He continuously communicates with Denji through dreams, warning him to not 'Open the Door'.

Pochita deeply cared for by Denji, after his life was saved by the human, despite the devil's general hatred toward humankind. He willingly gave up his heart to Denji so that he could fulfill his dreams which Pochita loved hearing about.

History
Pochita initially met Denji after suffering wounds from an unknown source while Denji was visiting his mother's grave. In an act of empathy, Denji offered Pochita his blood so that he could recover from his wounds on the condition that the two would become partners. Pochita would live alongside Denji, assisting him in devil hunting and wood clearing while subsisting on whatever rations Denji could afford.

Intro arc
One day, both are mortally wounded by the Zombie Devil and his Yakuza turned zombies. Pochita would then enter Denji's body, assuming the role of his heart, while repairing Denji's damaged or missing organs and body parts in the process. Pochita is last seen communicating with Denji internally, communicating his wish that Denji show him more of his dreams in exchange for being his heart.

Control Devil arc
TBA.

Abilities
Devil Erasure: The Chainsaw Devil is capable of consuming other Devils, erasing them from the public conscious, this makes them incapable of reviving as the fear of them no longer exists, shown by the fact that Kishibe didn't know about historical things such as the holocaust, Nazis, and even the Nuclear bomb, revealing that the Chainsaw Devil at some point consumed their relative Devils.

Chainsaw Appendage: Protruding from Pochita's head is a chainsaw shaped appendage that functions as an actual chainsaw. This ability is activated when the chord in his tail is pulled. As a full devil, all four of his arms have chainsaws.

Contract Creation: As a devil, Pochita can bestow contracts upon humans for a price. Their first contract with Denji is in exchange for consuming Denji's blood, Pochita assists him to pay him debts. However, it is not confirmed as a real contract.
 * Body Assimilation: Pochita possesses the ability to fuse with a human body seemingly replacing damaged or missing organs. Unlike the process for a devil turning into a fiend by taking over a corpse, Pochita did this to Denji while he was still alive which allows Denji to transform into human/devil hybrid. It is later revealed by Makima that this fusion is occurred as a result of contract. In exchange for Denji living a "normal life", Pochita becomes heart of Denji.
 * Full Devil Mode: After Denji has surrendered his contract with Pochita, he transformed into a Full Devil. In this form, the Chainsaw Man displays incredible speed and strength, easily defeating multiple Hybrid-Devils in a matter of seconds. Though he has been shown to have taken damage, and even been slowed by being sent to Hell and blasted into Space, these acts merely delayed him for a few minutes before he returned unscathed. His immense power is further highlighted in Hell, where it is implied he defeated every Demon residing there. Makima stated that he has killed her 26 times in this form. The form seems to under control of Pochita as it is shown that he remembers the Denji's dream and tries to fulfill the requirements of their contract by eating a hamburger and dating with a girl. After defeated by Makima to save Kobeni and later rescued by Power, Denji transformed back to normal and regained his consciousness.

Blood Consumption: As a devil, Pochita can restore his health by consuming blood. As a full Devil, he fully regenerated from just his heart after throwing it from space.
