Locust Devil

Standing tall and broad across the shoulders, the Locust Devil wears a heavily segmented body that reads as part insect, part hulking brute. Four broad wings sprout from its back in the manner of a real locust, and seen from behind these long, overlapping panes swallow its outline, hinting at swarms more than at actual flight. Its head sits small atop the wide torso, stripped of human detail and closer to a blank insectoid mask, with two slender antennae rising from it. Uneven slabs of chitin armor the bulky, lopsided frame, while four heavy arms end in blunt hands and stubby, claw-tipped fingers. Mismatched legs and a stiff, looming stance round out a silhouette that feels caught between eerie stillness and the promise of sudden violence.

The source reveals little about its inner life. Being a non-human devil, it is taken to bear an instinctive hatred of people, and its conduct seems geared toward devouring and spreading rather than any kind of dialogue, an echo of the blind, total ruin that real locust swarms bring.

The creature surfaces during the War Devil arc, deep in Hell, just after Yoru flings Denji into a nearby sea and orders him to admit defeat. The Locust Devil intercepts her instead. Yoru fires into its chest and nearly severs its head, leaving it hanging by a thread of flesh, yet it answers by driving a pincer through her and pinning her to a wall as Denji breaks the surface. He urges Yoru to give up, but the sight of Asa pleading for rescue forces his hand. The collision rips open a gateway out of Hell, and the three crash back onto Earth, where Denji cuts the devil down after prying Yoru loose, trading one of his arms for one of its own.

Shrugging off the wound, the Locust Devil snatches Denji by his rope of intestines and hurls him through a row of buildings, then closes in to bury him under living swarms of locusts. The tide turns when Asa restores Denji's lost arm; it reattaches and fires a chain clean through the devil's body. Denji hauls the creature in, runs his chainsaws through it, and reduces it to scraps before swallowing its head whole, afterward noting that it tastes like shrimp. Throughout the fight the devil shows off the brute toughness and raw power typical of its kind, soaking up gunfire and head wounds while striking hard enough to take a limb.
