Who Is the Bat Devil?

The Bat Devil is a devil who embodies the concept of bats and draws power from the human fear of bats. The Bat Devil stands as the first devil Denji faces as a Public Safety devil hunter. The Bat Devil gives the Bat Devil Arc its name, and the arc runs from Chapter 5 to Chapter 9. The arc appears in the guide to Chainsaw Man arcs in order.
The Bat Devil matters because the Bat Devil forces the first real partnership between Denji and Power. Power betrays Denji to the Bat Devil, the Bat Devil breaks the bargain with Power, and Denji defeats the Bat Devil to free Power and Meowy. The fight shows Denji fighting to protect others for the first time.
What Does the Bat Devil Look Like?

The Bat Devil in the first incarnation looks like an enormous humanoid bat with a grotesque face, multiple sharp teeth, large round eyes, and a muscular body. The arms connect to the torso through flaps of skin, and the flaps serve as wings. The body has dark-purple colouration in the manga, and the body changes to dark-grey in the anime.
The Bat Devil enters the story missing an arm. Human hunters cut off the right arm, and the Bat Devil hides in an abandoned house while the wound heals. The Bat Devil regrows the severed arm after drinking the blood of Denji, and the Bat Devil loses the same arm again in the fight with Denji.
The Bat Devil in the second incarnation looks more rabid, furrier, and less defined than the first incarnation. The eyes bulge constantly, and the snout appears fleshier and leads into a mouth that hangs always agape, full of jagged teeth. The muscle mass of the first incarnation disappears. The fur of the arms ends at the elbows, and the feet develop into eagle-like talons.
What Is the Bat Devil’s Personality?

The Bat Devil in the first incarnation has a cruel, gluttonous, and refined personality, built around hatred of humans and a love of eating humans. The Bat Devil hates humans because human hunters cut off the arm of the Bat Devil and forced the Bat Devil into hiding. The Bat Devil treats humanity as a menu of different meals, and the Bat Devil judges each meal by taste.
The Bat Devil holds a refined sense of taste. The Bat Devil calls the blood of Denji disgusting, and the Bat Devil calls Power disgusting after swallowing Power. The Bat Devil prefers children above other humans, and the Bat Devil prefers humans with perfectly healthy bodies. The Bat Devil flies toward the city to eat children after the disgusting blood of Denji.

The Bat Devil possesses 6 main powers and abilities: bat wings and flight, a mouth cannon, blood consumption and regeneration, enhanced strength, enhanced durability, and an enhanced sense of smell. The Bat Devil holds all of the standard devil abilities. The second incarnation weakens greatly and loses most of the unique abilities of the Bat Devil.
Bat wings and flight: The Bat Devil extends the wings and flies through the air despite the enormous size of the Bat Devil. The Bat Devil flies very fast, and the Bat Devil crosses large distances in a very short period of time. The Bat Devil flies from the abandoned house toward the city while carrying Power and Meowy inside the stomach of the Bat Devil.
Mouth cannon: The Bat Devil compresses the mouth into a gun-barrel shape that extends from the face of the Bat Devil. The Bat Devil fires an immense blast of air pressure through the mouth cannon, and the blast demolishes buildings.

Enhanced strength, durability, and smell: The Bat Devil strikes through the ceiling of a house with a single punch, and the punch creates a hole for the Bat Devil to crawl through. The Bat Devil picks up a car with just one arm and throws the car at Denji.
The Bat Devil survives being punched through walls and falling from the sky without visible injuries. The Bat Devil smells the scents of humans in the city from a distant building, and the sense of smell helps the Bat Devil choose prey.

The Bat Devil encountered Power in the countryside, and the Bat Devil took Meowy prisoner to force Power to cooperate. The Bat Devil demanded that Power bring a human, and the Bat Devil promised to return Meowy in exchange for the human.
Power offers Denji a deal in Chapter 5 to recover Meowy. Power promises to let Denji touch the chest of Power, and Denji accepts the deal. Power then knocks Denji unconscious in Chapter 6, “Service”, and Power drags Denji into the abandoned house of the Bat Devil as the promised human.

How Does the Bat Devil Die the First Time?
The Bat Devil dies the first time in Chapter 8, “Chainsaw vs. Bat”, when Denji as Chainsaw Man cuts the Bat Devil to pieces. Denji cuts the Bat Devil while the two fall from the sky, and Denji cuts off the arm the Bat Devil had just regrown. The two crash through the roof of a building in the city, and Denji scares an onlooker into running away from the battle.
Denji punches the Bat Devil out of the building with the chainsaws of Denji, and the fight moves to the streets. The Bat Devil picks up a car to throw at Denji, believing that Denji would save the human inside the car. Denji catches the car, and Denji throws the car back into the face of the Bat Devil instead of saving the man inside the car.
The Bat Devil shapes the mouth into a cannon and blasts Denji into the building behind Denji. The Bat Devil picks up a human to devour the blood of the human and regenerate, and Denji emerges from the rubble intact.
