One Punch Man Hero Rank Generator

Free One Punch Man hero rank generator: get your Hero Association class (C to S), numbered rank, a deadpan OPM hero name, the highest disaster level you could handle, and the canon hero whose seat you take. Full class, S-Class and disaster-level charts.

Quick answer

Type your name to get your Hero Association rank — class, seat number, hero name and disaster-level clearance. The roll is weighted like the canon registry (390 C-Class, 101 B-Class, 38 A-Class, 17 S-Class of 546 heroes), so S-Class is a rare ~3% pull, and the same name always registers the same hero.

What Hero Rank Would You Be?

In One Punch Man, being a hero is a registered profession with a published league table — and everyone in the series cares desperately about the numbers except the one man who should. This One Punch Man hero rank generator answers the question every fan asks: what hero rank would I be? Type your name and it hashes into a stable seed, then rolls your class (C, B, A or S), your numbered rank within that class, a properly deadpan One Punch Man hero namein the Association's registry style, the highest disaster level you'd be cleared for, and the canon hero whose seat you take. Same name, same rank, forever — so the results are settled, not argued.

How the Hero Association Ranks Its Heroes

Every professional hero passes the same entrance exam — a fitness test and a written test — and almost everyone starts at the bottom of C-Class, where you must log hero work every week or be struck off the registry. Promotion is brutally simple: reach Rank 1 of your class, then choose to move up and start again near the bottom of the next one. Only an exceptional exam score (or a reputation like King's) places a hero directly into a higher class. Of the 546 heroes registered before the Monster Association arc, 390 were C-Class, 101 B-Class, 38 A-Class and just 17 S-Class — this generator rolls your class with exactly those weights, which is why S-Class comes up about 3% of the time, like a proper hero association rank test should.

C-Class390Pass the entrance exam (fitness + written) — nearly everyone starts here, and you must log hero work every week or be struck off the registry.Mumen Rider (C-1), Gearsper (C-133), Saitama on debut (C-342)
B-Class101Reach Rank 1 in C-Class and choose to climb. The weekly quota disappears — but the Blizzard Group is waiting for you.Fubuki "Blizzard of Hell" (B-1), Saitama for most of the story (B-7), Captain Mizuki (B-71)
A-Class38Reach Rank 1 in B-Class, or ace the exam outright. A-Class heroes are celebrities — and must run seminars for new recruits.Sweet Mask (A-1), Iaian (A-2), Death Gatling (A-8), Stinger (A-10), Sneck (A-37)
S-Class17Be scouted as a one-person army: S-Class was created for heroes who beat Demon-level monsters alone. King and Genos were placed here directly.Blast (S-1), Tatsumaki (S-2), King (S-7), Genos "Demon Cyborg" (S-14)

Class sizes as counted before the Monster Association arc (546 registered heroes, ch. 40). Sourced from the One Punch Man Wiki — the table is canon; the rank you personally roll is a name-seeded fan mechanic.

Why Rank Never Equals Strength

The running joke of the series is that the ladder measures paperwork as much as power. Mumen Rider, C-Class Rank 1, is an ordinary man on a bicycle who charges Demon-level monsters anyway; King, S-Class Rank 7, is “the Strongest Man on Earth” and has never thrown a punch in his life. Saitamabroke every record in the fitness exam and was still filed at the bottom of C-Class over his written test, then spent most of the story stuck around B-7 while casually deleting threats the entire S-Class couldn't stop. When the generator seats you beside a canon hero, remember which side of that joke they may be on. The S-Class table below is the classic 17-seat roster the anime and most of the manga use — every seat verified.

The S-Class, seats 1–17

RankHeroWhy they hold the seat
S-1BlastThe Association’s phantom top hero — appears only when he feels like it.
S-2Tatsumaki — Tornado of TerrorThe most powerful esper alive; brings down alien warships by hand.
S-3Bang — Silver FangMaster of Water Stream Rock Smashing Fist; strongest martial artist.
S-4Atomic Samurai (Kamikaze)A swordmaster who reduces Demon-level monsters to sashimi.
S-5Child EmperorA boy-genius gadgeteer — the smartest hero in the Association.
S-6Metal Knight (Bofoi)Never shows up in person; sends remote-controlled war machines.
S-7King"The Strongest Man on Earth." Has never thrown a punch in his life.
S-8ZombiemanCannot die. Investigates the Association’s ugliest cases, forever.
S-9Drive KnightA transforming combat android with an agenda of his own.
S-10Pig GodSwallows Demon-level monsters whole. That is the entire technique.
S-11Superalloy DarkshinePeak muscle and mirror-polished invulnerable skin.
S-12Watchdog ManGuards Q-City alone, in a dog suit, on all fours. It works.
S-13Flashy FlashThe fastest hero alive — a ninja who ended two Dragon-level assassins.
S-14Genos — Demon CyborgSaitama’s disciple; rebuilt stronger after every defeat.
S-15Metal Bat (Bad)One bat plus Fighting Spirit — the longer he fights, the stronger he gets.
S-16Tanktop MasterLeader of the Tank Topper Army. The tank top is load-bearing.
S-17Puri-Puri PrisonerAngel Style master who breaks out of prison whenever justice calls.

The classic Monster Association–era numbering (each rank verified against the One Punch Man Wiki). In the latest manga chapters Genos has risen to S-11, King to S-5, and Silver Fang, Child Emperor, Metal Bat and Superalloy Darkshine have resigned, leaving 13 active seats.

The Disaster Levels: How Big a Threat Could You Handle?

The Association grades monsters the way it grades heroes — on a published scale: Wolf, Tiger, Demon, Dragon, God. Canon even gives the exchange rate: an average Wolf-level threat takes one B-Class hero (or three C-Class working together), a Tiger takes one A-Class, and a Demon takes one S-Class — the class was literally created for heroes who beat Demon-level monsters alone. Your clearance is mapped straight from that scale, with only the top five S-Class seats cleared for Dragon; nobody, not even Blast, is cleared for God.

Frequently Asked Questions

What hero rank would I be in One Punch Man?

Type your name into the generator above and it hashes into a stable seed, then rolls your Hero Association class and numbered rank weighted exactly like the canon registry — 390 C-Class, 101 B-Class, 38 A-Class and 17 S-Class of 546 registered heroes. That makes C-Class the overwhelmingly likely result (as in the series) and S-Class a rare ~3% pull. The same name always returns the same rank, so you can compare with friends.

How many S-Class heroes are there in One Punch Man?

The classic S-Class roster has 17 numbered seats, from Blast at S-1 down to Puri-Puri Prisoner at S-17 — the lineup used through the Monster Association arc and the anime. In the latest manga chapters the seats have shifted (Genos has climbed to S-11 and King to S-5) and four members — Silver Fang, Child Emperor, Metal Bat and Superalloy Darkshine — have resigned, leaving 13 active S-Class heroes.

What are the hero classes in One Punch Man?

The Hero Association sorts its heroes into four classes — C, B, A and S — each with individually numbered ranks. Before the Monster Association arc there were 546 registered heroes: 390 in C-Class, 101 in B-Class, 38 in A-Class and 17 in S-Class. Nearly everyone starts at the bottom of C-Class after the entrance exam; S-Class is reserved for heroes who can beat Demon-level monsters single-handedly.

What are the disaster levels in One Punch Man?

The Hero Association grades threats on five disaster levels: Wolf (a being that might pose a threat), Tiger (danger to a great number of people), Demon (danger to a whole city), Dragon (danger to multiple cities) and God (danger to the survival of all humanity). The official comparative scale says an average Wolf takes one B-Class hero, a Tiger one A-Class, and a Demon one S-Class — which is exactly how this generator maps your clearance.

How do heroes rank up in the Hero Association?

Points are awarded for defeating monsters, public contribution and popularity; to be promoted to the next class you must first reach Rank 1 in your current class, then choose to move up and start near the bottom of the class above. Exceptionally high exam scores — or a record like King’s — can place a hero directly into a higher class. The system is famously bureaucratic: Saitama broke every physical exam record and was still placed at the bottom of C-Class because of his written test.

Who is the number 1 hero in One Punch Man?

Blast is the S-Class Rank 1 hero — the Hero Association’s mysterious top hero, who appears only when he feels like it. Each class has its own number one as well: Sweet Mask holds A-1, Fubuki the "Blizzard of Hell" holds B-1, and Mumen Rider — the bravest man in the series — holds C-1.

Is this hero rank generator canon-accurate?

The class sizes, the S-Class 1–17 roster, the notable named ranks and the disaster levels are all straight from One Punch Man canon (sourced from the One Punch Man Wiki), and the reference tables below list them exactly. The rank you personally roll and your generated hero name are a labelled fan mechanic seeded from your name — a bit of fun, not an official Association evaluation. What is fixed is that the same name always produces the same result.
