The #4 Hero Ranking: Breaking Down Deku’s Return and Technology
When the dust settled on the final battle against All For One, many readers feared that Izuku “Deku” Midoriya’s story had reached a bitter end. The loss of One For All felt like a profound erasure of his decade-long journey from a powerless boy to the savior of society. Yet, Kohei Horikoshi had one final surprise in store. The reveal of Deku’s specialized hero armor—fully realized in the aftermath of the series and highlighted in the 2026 OVA—proves that Midoriya didn’t just return to hero work; he returned as a powerhouse.
By securing the #4 spot on the Japanese Hero Rankings, Deku has silenced the doubters. This isn’t a mere participation trophy; it is a tactical evolution. Through the integration of advanced support tech, Deku has successfully bridged the gap between his Quirkless reality and his former status as the world’s greatest hero.
Key Takeaways: The New Era of Deku
| Feature | Details |
| Current Rank | #4 Hero in Japan |
| Primary Power Source | All Might’s Advanced Hero Armor |
| Technology Origin | Post-Final War development (8-year project) |
| Functional Goal | Replication of One For All (OFA) and Vestige abilities |
| Top Competitors | Mt. Lady, Shoto Todoroki, Mirio Togata |
The Genesis of the Armor: Technology Replacing Quirks

To understand why this armor is significant, you must look at how the power gap was managed after the war. For eight years, the world’s greatest minds—spearheaded by All Might and a team of top-tier support technicians—worked to develop a suit capable of housing the kinetic output required for professional hero work.
The armor isn’t just a physical shell; it is a complex, high-output interface. All Might, recognizing that Deku could not simply walk away from his calling, treated the project as his final masterpiece. The suit utilizes advanced capacitors and micro-thrusters to mimic the internal structure of One For All. By channeling energy through the suit’s internal network, Deku can replicate the sensation—and the sheer force—of the stockpiled power he once called his own.
How the Tech Mimics the Vestiges
The genius of the design lies in its versatility. Horikoshi confirmed that the suit is a modular platform. It doesn’t just mimic physical strength; it attempts to map the unique signatures of the various quirks Deku previously wielded:
- Black Whip Extensions: The armor features cable arrays that act as synthetic tendrils, allowing Deku to grapple and restrain targets with precision.
- Tactical Simulation: Much like the vestige quirks provided utility, the suit’s internal AI analyzes environmental data to suggest power outputs, effectively acting as a modern-day substitute for Danger Sense.
- Modular Upgrades: Because the suit is hardware-based, it can be patched and tuned. If a situation requires more mobility or defensive plating, Deku can swap internal components, a luxury he never had with his biological Quirk.
Understanding the #4 Hero Ranking
Rising to #4 in the rankings is a massive feat, especially for someone who, by public records, is technically Quirkless. The Hero Public Safety Commission and the Japanese public judge rankings based on a blend of three criteria: Incidents Resolved, Public Approval Ratings, and Threat Mitigation.
Deku’s rapid ascent is fueled by his experience. While other heroes are learning to manage their quirks in the post-war world, Deku already has the tactical mindset of a veteran. He knows the villains, he knows the terrain, and he knows how to keep civilians safe. He isn’t just “strong”; he is efficient.
Current Top Tier Comparison
| Hero | Role/Strength | Why Deku is Chasing Them |
| Mt. Lady | High-scale disaster response | Her size and public presence are currently unmatched. |
| Shoto Todoroki | Precision and elemental control | He has fully mastered his dual-nature quirk. |
| Mirio Togata | Mobility and untouchable defense | His mastery of Permeation makes him nearly impossible to pin down. |
Deku’s challenge is that he is essentially testing a prototype against seasoned pros who have had their full toolkits for years. However, history shows that Midoriya adapts faster than anyone else in the industry. His rise to #4 is likely just the starting point of a trajectory aimed squarely at the top.
The Science of the “New” One For All
The most common question regarding Deku’s return is: “Is he actually back at 100%?”
Technologically, the answer is a complicated “yes.” The armor functions by pulling from a high-density battery bank designed by the same minds that kept All Might operational after his organs were crushed. By mimicking the stockpiling effect, the suit allows Deku to output power levels that rival his output during the War Arc.
He can initiate bursts of speed that mimic Gear Shift and defensive barriers that rival Float. The “science” here is a mix of high-energy physics and brute-force engineering. If the armor requires a massive jump in power, the suit draws on the battery, which is designed to withstand higher temperatures than the human body could ever endure. This is where Deku might actually possess an edge over his former self; the suit doesn’t break his bones when he pushes past 100%.
Looking Ahead: The Path to #1
Why are we so confident he will eventually take the top spot? It comes down to the nature of the My Hero Academia world. The hierarchy is meritocratic, and Deku is the ultimate meritocrat.
With Horikoshi moving on to new projects, the status of the world remains in a state of “peaceful maintenance.” However, in narrative terms, the #4 ranking serves as the perfect cliffhanger. It establishes that Deku has found his footing, yet leaves room for the inevitable threat that will force him to push his armor to the absolute limit.
We shouldn’t expect him to reach #1 overnight. The current Top 3 are all at the peak of their careers. But for a hero whose entire life was defined by the mantra “I’ll make it,” the road to #1 is already mapped out. He is currently learning the limits of his hardware, refining his fighting style to account for the armor’s weight and response time. Once he synchronizes his natural analytical genius with the suit’s capabilities, the top spot is effectively his to lose.
Frequently Asked Questions
Is Deku truly Quirkless now?
Yes. Following the events of the Final War, Deku possesses no active Quirk. His powers are strictly derived from the support technology provided by All Might and his team of technicians.
Can the armor break or run out of power?
The armor is a machine and is subject to the same laws of maintenance as any piece of support gear. While it is built for extreme durability, sustained high-output usage drains the internal battery, necessitating “recharge” periods, similar to how he managed energy management with his Quirk.
Will we see more of Deku in the future?
While Kohei Horikoshi is currently focusing on new projects, the open-ended nature of the Hero Rankings and the world-building established in the 2026 OVA suggests that the door remains wide open for future short-form stories or spin-offs focused on the next generation of pros.
How does the armor compare to the All Might suit?
Deku’s armor is a direct evolution of the prototype suit All Might used. It incorporates years of data gathered from the Final War, meaning it is lighter, more maneuverable, and specifically tuned to match Deku’s unique combat style rather than All Might’s heavy-hitting approach.
Why is Mirio Togata ranked higher than Deku?
Mirio remains one of the most capable heroes in Japan. His combination of experience, absolute control over his Quirk, and high public approval rating makes him a difficult benchmark for any hero to surpass, even one as talented as Midoriya.
