Analysis of the U.S.J. Villains in My Hero Academia

The U.S.J. (Unforeseen Simulation Joint) Incident was the League of Villains’ first major attack in My Hero Academia, occurring early in the series. Tomura Shigaraki and Kurogiri led about 70 low-ranking villain recruits, many being original one-off characters introduced during the arc. They were divided into specialized combat groups to take advantage of their Quirks and the terrain inside the different U.S.J. zones.

1. Overview of the U.S.J. Villains

Purpose: The villains’ stated goal was to kill All Might and terrorize U.A.; however, a large portion of their role was to distract and potentially kill students long enough for the Nomu to fight All Might.

Composition: Mostly disposable hired thugs / minor villains, many of them “F-rank” or “E-rank,” with a handful of more dangerous combatants.

Organization: Tomura placed enemies into different specialized areas (Flood Zone, Mountain Zone, Conflagration Zone, etc.) to trap students in unfavorable terrain.

Outcome: Despite sheer numbers, the villains were badly outclassed by the U.A. staff and heroic students. Nearly all were defeated and arrested during or immediately after the incident.

2. Key Offensive Groups & Examples

A. Long-Range & Fire Support Villains

Victor – Finger Gun Quirk, could fire bullets from fingertips. Taken out by Aizawa early when his Quirk was erased.

Needle Hair – Hardened hair projectiles; also shut down by Erasure.

Stitched Giant – Mutant Bovini Quirk; fired lasers from face, defeated before contributing.

Thousand Eyes – Rune-paper body; could attack at range and make clones — rendered useless by Quirk nullification.

Assessment: These villains’ main advantage (distance attacks) vanished instantly once Aizawa targeted them, revealing the League's lack of anti–Erasure strategy.

B. Close-Combat / Brute Force Villains

Steel Bulwark – Extra arms, mutant body; thought immunity to Erasure would make him unstoppable, but was easily restrained by Aizawa’s Binding Cloth.

Muscle Man – Charging Muscles Quirk; brute melee fighter, but telegraphed attacks.

Minotaurus – Horned cyclops; big but slow, folded instantly against All Might.

Sickle Claw – Iron claw hands; tried to take advantage when Aizawa was injured but failed.

Hard Head – Muscle expansion; neutralized quickly by Denki’s electricity.

Assessment: Physically powerful but either overconfident, predictable, or lacked teamwork. Most went down in one or two clean hero counters.

C. Aquatic / Flood Zone Villains

Dozaemon – Water Control Quirk; seemed more tactical and patient, but ultimately trapped by Mineta’s sticky balls after Izuku’s whirlpool maneuver.

Bye-Bites – Shark-like melee specialist; fast underwater but too cautious at first.

Oxy-Man – Generated oxygen for underwater combat; lacked offense.

Assessment: Strong in specialized environment, but unable to capitalize before students figured out countermeasures. Proved dangerous in theory, but poor coordination led to total defeat.

D. Specialized / Utility Abilities

Chomper – Plant transformation with healing properties; essentially support role, little combat impact here.

Martial Hair – Ponytail-based hair weapons; intercepted and KO’d instantly by Aizawa.

Gravitational Spring – Long, tether arms; temporarily tagged Denki, but was vulnerable to multi-target attacks.

Tesla – Electric immunity & signal interference; tactically smart — hostage strategy against Jiro, Momo, and Denki — but was stopped by Snipe in one precise shot.

Invisible Wall – Chameleon camouflage; decent at ambush, but predictable. Katsuki saw through him and blasted him point-blank.

Assessment: Some of these could have been dangerous with better team synergy or leadership, but poor execution and over-reliance on ambush failed in the face of experienced heroes.

E. Filler Horde & Minor Assailants

One-Eyed Green Dragon, Greedy Gaping Jaw, Berserker, Sharp Blade, Giant Palm, Axer, Gorilla, Varanus, Spike, Dragon (Villain), Yashamaru, Mummy, etc. Many of these had either underdeveloped Quirks or brute physicality overshadowed by sheer incompetence. Common pattern:

Rush the heroes head-on

Get countered in one move

Arrested

3. Tactical Failures

Lack of Preparation for Erasure: The majority of villains’ offense was completely nullified by Aizawa’s Quirk, revealing poor intel or arrogance in strategy.

Overconfidence: Many low-tier villains assumed that overwhelming numbers could beat pro heroes — underestimating training and combat experience.

Poor Leadership: Shigaraki largely left the 70 fodder villains to fend for themselves rather than directing coordinated assaults. This led to scattered skirmishes easily controlled by the heroes.

Reliance on Surprise Only: Once initial shock wore off, students adapted and exploited terrain just as well (if not better) than their attackers.

4. Notable Post-U.S.J. Appearances

While most were never seen again, a few minor U.S.J. villains reappeared in later arcs:

Steel Bulwark & Dozaemon – Participated in Final War riot & Okuto Island battle respectively before reapprehension.

Chomper & Victor – Appeared in manipulated footage during the Deika City events (Meta Liberation Army Arc).

The rest either disappeared from narrative focus or became background filler for villain crowds.

5. Overall Analysis

The U.S.J. Villains were:

Cannon fodder for the League's first attack.

Effective only in surprise and against unprepared/isolated students.

Completely ineffective against pro heroes due to poor coordination, lack of anti-counter measures, and reliance on raw Quirk output over strategy.

Narrative Purpose:

Demonstrate U.A.'s crisis response and the competency gap between pros & amateurs.

Show off students’ adaptability under lethal pressure.

Insights & Analysis

Narrative Purpose:

These villains serve as fodder to demonstrate the combat prowess of U.A. students and Pro Heroes, particularly Eraser Head’s tactical skills and All Might’s overwhelming power.

Their varied Quirks highlight the diversity of threats in the My Hero Academia universe, setting the stage for the League of Villains’ larger schemes.

Group Dynamics:

Organized into specialized groups (e.g., Shooting Squad, Flood Zone), reflecting Tomura’s strategic planning under All For One’s influence.

Their overconfidence and underestimation of U.A.’s defenders underscore the League’s initial inexperience.

Thematic Role:

Represent the societal outcasts manipulated by All For One, paralleling the AFO Orphanage’s exploitation of vulnerable children.

Their quick defeat emphasizes the strength of heroism and teamwork, a core theme of the series.

Later Impact:

Villains like Steel Bulwark and Dozaemon reappear in the Final War Arc, showing the lingering threat of escaped convicts and the Paranormal Liberation Front’s influence.

Their re-arrest reinforces the heroes’ ultimate triumph.

Comparative Notes

Contrast with AFO Orphanage:

Unlike the orphanage’s psychological manipulation, the U.S.J. villains are direct combatants, reflecting All For One’s use of both overt and covert strategies.

The orphanage exploits children’s potential, while these villains are disposable tools, highlighting AFO’s utilitarian approach.

Quirk Diversity:

Quirks range from biological (e.g., Invisible Wall’s Chameleon) to mechanical (Victor’s Finger Gun) and elemental (Dozaemon’s Water Control), showcasing the spectrum of abilities in the MHA world.

Mutant Quirks (e.g., Steel Bulwark, Minotaurus) are immune to Erasure, posing unique challenges compared to transformation-based Quirks (e.g., Needle Hair, Martial Hair).

Personality:

Most lack developed personalities, serving as archetypes of villainous confidence, with exceptions like Tesla (strategic, empathetic to electric Quirk users) and Bye-Bites (sadistic).

Trivia

Many villain names (e.g., Needle Hair, Stitched Giant, Tesla) are exclusive to My Hero Academia: The Strongest Hero, not appearing in the main manga/anime.

Shared voice actors (e.g., Dozaemon with Cementoss, Bye-Bites with Mr. Compress) reflect efficient casting in the anime.

Names like Dozaemon (homophonous with “sayonara”) and Varanus (monitor lizard genus) add thematic depth to their designs.

Summary

The U.S.J. Arc’s minor villains, recruited by Tomura Shigaraki, are a diverse group of low-ranking antagonists whose primary role is to challenge U.A.’s heroes, highlighting their skills and the League’s early ambitions.

Their varied Quirks and quick defeats underscore the series’ themes of heroism and the exploitation of societal outcasts by All For One.
