Who Is the Locust Devil?
The Locust Devil is a devil who embodies the concept of locusts and large-scale infestation and draws power from the human fear of insect swarms, crop destruction, and famine. The Locust Devil serves as a minor antagonist of the War Devil arc, and the War Devil arc covers the final battle between Denji and Yoru in Part 2. The arc appears in the guide to Chainsaw Man arcs in order.
What Does the Locust Devil Look Like?
The Locust Devil looks like a tall, broad-shouldered humanoid with a heavily segmented, insect-like body covered in uneven chitinous plating. The head of the Locust Devil is small relative to the torso and lacks distinct human features, resembling an insectoid mask instead. A pair of long, thin antennae extends from the head of the Locust Devil.
The Locust Devil has four thick arms ending in large, blunt hands with short, claw-like fingers. The legs of the Locust Devil are unevenly proportioned, and the physique of the Locust Devil is bulky and asymmetrical. The crude, swarm-formed build of the Locust Devil gives the Locust Devil an obsolete, predatory appearance.
Four large, rigid wings resembling the wings of a locust extend from the back of the Locust Devil. The elongated, overlapping wings dominate the silhouette of the Locust Devil when viewed from behind. The wings emphasize the association of the Locust Devil with swarms rather than with flight.
What Is the Locust Devil’s Personality?
Little is known about the personality of the Locust Devil, because the Locust Devil speaks no dialogue of substance across Chapters 226 and 227. The Locust Devil behaves with instinctive hostility toward humans, as a non-humanoid devil driven by consumption and spread rather than by communication.
The behavior of the Locust Devil mirrors the indiscriminate devastation caused by locust swarms. The Locust Devil attacks Yoru without negotiation, warning, or contract, and the Locust Devil continues to fight after suffering wounds that would stop a lesser devil.
What Are the Locust Devil’s Powers and Abilities?
The Locust Devil possesses 3 main powers and abilities: swarm manifestation, immense durability, and immense strength, along with all of the standard devil abilities. The power of the Locust Devil comes from the fear of locusts, insects, and the famine that follows a swarm.
Swarm manifestation: The Locust Devil summons large numbers of locust-like creatures to overwhelm opponents. The Locust Devil engulfs Yoru in a swarm the moment the Locust Devil emerges in Hell, and the swarm leaves Yoru unable to react to the return of Denji. The Locust Devil unleashes successive swarms upon Denji in Chapter 227 while Denji lies buried beneath rubble.
Immense durability: The Locust Devil withstands severe physical damage with little visible impairment. Yoru shoots the Locust Devil in the chest and mostly cuts off the head of the Locust Devil, leaving the head dangling by a small cord attached to the torso. The Locust Devil continues to fight after sustaining holes throughout the body of the Locust Devil and after the partial severing of the head.
Immense strength: The Locust Devil overpowers Denji in close combat with raw physical force. The Locust Devil strikes Denji with enough force to sever the arm of Denji, even while enduring repeated attacks from Denji. The Locust Devil grabs Denji and hurls Denji through multiple buildings, and the Locust Devil impales Yoru into a wall with one of the pincers of the Locust Devil.
How Did the Locust Devil Ambush Yoru in Hell?
The Locust Devil ambushed Yoru by emerging from a swarm of locusts in Hell in Chapter 226, “Locust’s Home”, while Yoru stood over the ocean of Hell demanding the surrender of Denji. Denji and Yoru had arrived in Hell during their battle, and Denji wondered aloud where all the devils of Hell had gone.
Yoru exploited the confusion of Denji by riddling Denji with bullets and blasting Denji into the ocean of Hell. Yoru ordered Denji to surrender, and a swarm of locusts suddenly engulfed Yoru before Denji could resurface. The Locust Devil emerged from the swarm and attacked Yoru directly.
Yoru shot the Locust Devil in the chest and mostly cut off the head of the Locust Devil. The head of the Locust Devil dangled by a small cord attached to the torso of the Locust Devil, and the Locust Devil retaliated by impaling Yoru into a nearby wall with one of the pincers of the Locust Devil. The wound left Yoru overwhelmed and unable to react.
Denji resurfaced from the sea and hauled himself back onto the platform of Yoru, remarking that Denji would have died in the water without the swimming skill Reze taught Denji. Denji taunted Yoru and demanded the surrender of Yoru, claiming the ambush formed part of the plan of Denji. Asa Mitaka then turned toward Denji and begged Denji to save Asa Mitaka.
The instincts of Pochita took over Denji, compelling Denji to confront the Locust Devil in order to protect Asa Mitaka. The clash between Denji and the Locust Devil tore through a door of Hell, forcing Denji, Yoru, and the Locust Devil back into the human world. The Locust Devil struck Denji down in the same instant, and the arm of Denji was sliced off in turn.
How Did Denji Defeat the Locust Devil?
Denji defeated the Locust Devil by reeling the Locust Devil toward Denji with a chain attached to the severed arm of Denji, impaling the Locust Devil with chainsaws, shredding the Locust Devil to pieces, and eating the head of the Locust Devil entirely. The defeat takes place in Chapter 227, “The Taste of Shrimp and Blood”.
The Locust Devil charged at Denji at the opening of Chapter 227, and Denji knocked the Locust Devil away. The Locust Devil latched onto Denji with an intestine scarf and hurled Denji through multiple buildings. Denji lay buried beneath the rubble, unable to move, while the Locust Devil unleashed successive swarms of locusts upon Denji.
Asa Mitaka recovered enough from the earlier injuries of Asa Mitaka to throw Denji the severed arm of Denji. The severed arm reattached itself immediately, and a chain shot out from the arm and pierced through the body of the Locust Devil. Denji yanked the chain forward, dragging the Locust Devil toward Denji.
Denji impaled the Locust Devil with chainsaws and shredded the Locust Devil to pieces. Denji devoured the corpse of the Locust Devil, and Denji remarked that the Locust Devil tastes like shrimp. Asa Mitaka smiled at the remark of Denji, and the meal closed the brief career of the Locust Devil as an antagonist.
Why Does the Locust Devil Matter in Chainsaw Man?
The Locust Devil matters because the Locust Devil exposes the emptiness of Hell at the climax of Part 2 and tests the plan of Denji to end the war with Yoru by eating a devil. Denji expects Hell to hold devils worth eating, and Hell holds almost nothing except an ocean and a single swarm devil. The failure of the plan of Denji shapes the chapters that follow Chapter 227.
The Locust Devil carries a second layer of meaning through the association between locust swarms and famine. Locust swarms devastate vast areas of crops and pasturelands within a short time, and locust swarms stand as a major cause and exacerbating factor of famine and severe food insecurity. The association links the Locust Devil, in theory, to Fami, the Famine Devil and one of the Four Horsemen.
The famine association remains a theory, not a confirmed fact of the story. The Locust Devil never meets Fami, never serves Fami, and never appears in a scene with Fami.
Locust Devil’s Relationships With Other Characters
Denji: Denji is the killer and eater of the Locust Devil, and the Locust Devil is the meal Denji sought in Hell. The Locust Devil severs the arm of Denji, hurls Denji through multiple buildings, and buries Denji beneath rubble under successive swarms.
Denji defeats the Locust Devil with a chain reeled from the severed arm of Denji, shreds the Locust Devil, and eats the head of the Locust Devil, remarking that the Locust Devil tastes like shrimp.
Yoru: Yoru is the first victim of the ambush of the Locust Devil and the reason the Locust Devil reaches Earth. The Locust Devil engulfs Yoru in a swarm, survives the gunfire of Yoru and the partial severing of the head of the Locust Devil, and impales Yoru into a wall with a pincer.
The injuries force Yoru to switch consciousness with Asa Mitaka, and the switch turns the fight into a rescue that drags all three combatants back to the human world.
Asa Mitaka: Asa Mitaka is the protected party in the fight against the Locust Devil and the supplier of the weapon that kills the Locust Devil. Asa Mitaka begs Denji to save Asa Mitaka while Yoru lies impaled, and the plea triggers the instincts of Pochita inside Denji.
Asa Mitaka throws Denji the severed arm of Denji in Chapter 227, and the chain attached to the arm lets Denji reel the Locust Devil into the killing blow.
