Nomus (My Hero Academia)

Nomus is the name given a species that feature in My Hero Academia.

History

Nomus (Japanese: 脳のう無む, Hepburn: Nōmu?) was the name given a number of individuals that were engineered to be living weapons. Their origins were traced to the villainous crime lord known as All For One who had the ability to steal Quirks which he either kept for himself or imparted them to others. After being injured, he remained in the shadows for years and performed experiments to transform people into artificial humans that obeyed his orders. These were creatures that were referred to only as Nomu and had no personality of their own with them simply following the orders of a superior. Typically, they had a number of Quirks installed in their bodies and were considered powerful enough to challenge heroes. In this time, All For One came to gain the assistance of a scientist named Dr. Kyudai Garaki who was secretly involved in the creation of the Nomu. These early experimentation work on a project that would allow them to create a being that would rival All Might in power, which would become the core purpose of the Nomu. Under the guise of the Villain Factory, these experiments included kidnapping people and preforming bio-engineering experiments on them, radically transforming their bodies and increasing their strength into what were known as Next-Level Villains. Doctor Kyudai also would take inspiration from All For One's bodyguard, Gigantomachia, a being of immense loyalty to his master, who's capability of possessing multiple Quirks made him a valuable and dangerous asset. The earliest known created Nomu was Kurogiri, a being made from the corpse of U.A. High School student Oboro Shirakumo. Through combining various different Quirk Factors, like Oboro's Cloud, his final Quirk was Warp Gate. Unlike future Nomu, Kurogiri did not possess great physical strength, but was capable of speech and free thought. He was primarily designed to act as a loyal ally for his creators, first as an assistant to All For One, and later as the watchful eye for Tomura Shigaraki. While Kurogiri did not have the memories of his time as Oboro, some of his personality traits remained within.

A Nomu accompanied Tomura Shigaraki and Kurogiri in their attack against the U.S.J.. Arriving via portal, the villains staged a large scale attack against the hero school with the Nomu's great strength allowing him to easily subdue the pro Eraser Head. This saw the students attempting to intervene where Izuku Midoriya attempted to take out Shigaraki but the Nomu intercepting the strike with its shock absorption Quirk. It was only the arrival of All-Might that turned the tide of the battle where Shigaraki revealed that Nomu was created to defeat the No. 1 Hero. This Nomu possessed shock absorption and super-regeneration, allowing it to withstand All Might’s devastating punches while countering with raw, unrelenting power. Its only purpose was to kill All Might, and it obeyed commands with unwavering loyalty, attacking him in a frenzied battle that shook the entire training ground. Despite its Quirks, the Nomu came to be overwhelmed by All-Might's strikes and he defeated the creature which came to be arrested by the police. This led to the authorities uncovering the true nature behind the Nomu and that originally he was just a small-time criminal whose body was modified to hold multiple Quirks. Their investigation led to them discovering a connection between the Nomu and All For One.

When the League of Villains deployed multiple Nomu across Hosu City, they demonstrated a wide variety of Quirks. Unlike the singular powerhouse at U.S.J., these were mid-tier models that prioritized mobility, speed, or elemental attacks, and they engaged both pro heroes and students in chaotic urban skirmishes. One Nomu nearly killed Tenya Iida before being brought down through the combined efforts of Stain, Shoto Todoroki, and Izuku Midoriya. Their presence revealed that Nomu were not unique creations but mass-produced weapons, grown and unleashed in packs to overwhelm opponents. The sheer scale of the Nomu deployment immediately plunged the urban centre into a state of chaotic terror. Three distinct specimens were released simultaneously, each acting with a singular, mindless drive to dismantle the peace of the night. The winged, four-eyed Nomu took to the skies, diving with predatory precision to snatch civilians from the streets and drop them from lethal heights, effectively turning the cityscape into a vertical hunting ground. On the ground, the massive green-skinned variant prioritised the destruction of infrastructure, smashing through reinforced concrete and upturning emergency vehicles with its immense physical power. Meanwhile, the dark-skinned, multi-quirked specimen engaged the Pro Heroes directly, absorbing their most potent attacks with its Shock Absorption ability and retaliating with overwhelming force that left several veterans incapacitated. As fires spread and the air filled with the scent of ozone and smoke, the Nomu moved with a chilling lack of self-preservation, ignoring severe injuries to continue their rampage. Their presence forced the heroes into a desperate, multi-front defensive struggle, serving as a brutal demonstration of the League's growing power while the 'Hero Killer' Stain operated in the shadows of the very same alleys. The tide of the battle finally turned as the Pro Heroes and U.A. students coordinated their efforts to neutralise the biological threats. The winged Nomu, which had been terrorising the skies, met its end when Endeavor incinerated its head with a concentrated blast of Prominence Burn, demonstrating the sheer lethality required to halt their cellular regeneration. Meanwhile, the green-skinned variant was suppressed through the combined strength of the local hero agencies, who pinned the creature down until it was eventually apprehended and restrained. The most resilient specimen, the dark-skinned Nomu, continued its rampage until it was caught in a fierce exchange with the No. 2 Hero; Endeavor used his superior firepower to carbonise the creature’s cells from the inside out, bypassing its Shock Absorption by targeting its internal organs with extreme heat. Even as the creatures fell, their defeat was overshadowed by the simultaneous capture of the Hero Killer, leaving the city in a state of grim reflection. By the time the sun rose over Hosu, the Nomu had been either incinerated or hauled away for medical study, leaving behind a scarred cityscape and a public deeply unsettled by the biological horrors the League was capable of manufacturing.

After All For One's defeat, a High-End Nomu was activated by the Hidamari Kindergarten where he went forth to complete his master's mission for him. This involved attacking the strongest hero at the time with this being the new number one pro hero named Endeavor who was meeting with a comrade named Hawks. Despite his power, Endeavor struggled in destroying the High-End Nomu who nearly killed him until he used a concentrated Prominence Burn attack that killed the intelligent hooded villain.

Overview

In appearance, the physical form of the Nomus varied greatly with some being muscular humanoids whilst others were winged creature. Nomus were largely humanoid but grotesquely altered, their bodies stretched and warped by experimental surgery. A common feature in them all was their monstrous form that had an exposed brain and large eyes on them. Their skin was often darkened or discolored, covered with thick muscle cords that gave them unnatural strength. Their faces were distorted, mouths too wide with jagged teeth, eyes sunken or vacant. Some Nomu were massive and brutish, while others were leaner and animalistic, depending on the design. Yet all of them bore the marks of their artificial creation, a blend of human structure and monstrous engineering. A Nomu could possess either a single Quirk or multiple Quirks in their bodies that enhanced their fighting potential.

Becoming a Nomu required more than just experimentation—it demanded the transformation of a human body through genetic manipulation under Dr. Garaki’s procedures. Ordinary humans, sometimes captured victims, were stripped of their Quirks or altered to accept multiple Quirks simultaneously. Their bodies were reforged through surgical enhancements and bioengineering until they could sustain the strain of Quirk stacking, which would ordinarily destroy a human body. Their consciousness was erased, leaving only an obedient husk that followed orders or instincts. Each Nomu was, at its core, a human being forcibly turned into a monstrous weapon against their will.

The abilities of the Nomu varied by type but all shared certain core traits. They possessed monstrous strength, capable of overwhelming even pro heroes in direct combat. Their durability was extreme, with many models able to regenerate from otherwise fatal wounds almost instantly. High-end Nomu were engineered with multiple Quirks, giving them both versatility and devastating combat power; some could fly, others wielded elemental abilities like fire or ice, while others moved with inhuman speed. Even the low-tier models remained formidable due to their relentless aggression, resistance to pain, and regenerative endurance. Above all, Nomu embodied the concept of living weapons—tools designed solely for combat, destruction, and obedience to their masters.

It was said that a Nomu with black skin possessed powerful regenerative abilities.

According to Doctor Garaki and All For One, there a few different grades of Nomu, and they're categorized into Lower-Tier, Middle-Tier, Upper-Tier, Near High-End, and High-End according to their physical enhancements and the amount of Quirks they possess.

• Kurogiri : a male created from the corpse of U.A. High School student Oboro Shirakumo where he came to be among the first created Nomus. Unlike the others, he had intelligence and capacity for speech where he was programmed to protect Tomura Shigaraki. He had the ability to create Warp Gates allowing for teleportation both for transportation and for use in offensive situations.
• High-End : a former underground fighter taken in to be transformed into a high-end hooded Nomu that wore a hood. He was imparted with six different Quirks that included super-strength, regeneration and transforming limbs but the most dangerous thing about him was him retaining some intelligence.
