15 Strongest One-Punch Man Characters You Won't Believe Are Ranked

One-Punch Man is a webcomic created and illustrated by ONE. It’s been available on the author’s personal site since June 3, 2009. The series has gained significant popularity, surpassing ten million total visits with an average of 20,000 daily visits.

In this write-up, we’ll delve into the most potent characters from the popular series “One-Punch Man”, presenting a countdown of fifteen key figures. We’ll arrange them in order of their overall might and abilities, with the least powerful at the top and the strongest at the bottom. By reading the article’s descriptions, you’ll be able to understand our reasoning behind each character’s position on the list.

15. Vaccine Man

Character named “Vaccine Man” is portrayed as an antagonist who seems to have a deep disdain for humanity due to their impact on the planet Earth, which he refers to as Mother Nature. He is believed to be the physical manifestation of her wrath. This character exhibits cruelty and ruthlessness, showing no mercy in his mission, which often involves damaging infrastructure or causing harm to people.

Because humans are causing harm to the planet, this individual believes it’s justified to annihilate them using extreme force, asserting that he is appointed by nature. His anger flares up when Saitama intervenes to halt his actions.

It triggers massive blasts that reduce structures like buildings, bridges, and highways to rubble, and leaves a colossal hole in the urban landscape. Subsequently, it ascends skyward and unleashes numerous orbs of devastating force. In the anime, it effortlessly overpowered Max and Smile Man, two formidable superheroes.

It triggers explosions of immense scale, reducing buildings, bridges, and roads to debris, leaving a mammoth crater in city centers. Rising high into the sky, it discharges multiple energy balls with destructive might. In the anime, it outmatched Max and Smile Man, two powerful superheroes without breaking a sweat.

In the midst of his destructive rampage, Vaccine Man spots a young girl amidst the debris, intending harm upon her. The intensity of his wish to eradicate her causes his arm to swell enormously.

14. Carnage Kabuto

Carnage Kabuto is an evolved beetle crafted by Genus, considered the mightiest creature within the House of Evolution. He’s a wicked and heartless entity, showing disdain even towards his creator, Genus, due to believing he himself represents perfection, eventually aiming to supplant humans.

He places high importance on self-reliance and becomes aggressive when upset, attacking anything in sight. His fascination lies with individuals portrayed as exceptionally powerful. In his encounter with Saitama, it’s clear he is petrified by anyone who demonstrates abilities far surpassing his own.

Initially, Saitama seemed like a fool, causing others to underestimate him and even forget the fear they once felt. It was Carnage Kabuto, initially introduced by his master, Professor Genus, who reappeared later on to challenge Saitama.

In a different wording: An attacking duplicate warns him to stay back, yet Scaravageur pays no mind and crushes him, as he had done with all previous duplicates. Eventually, the genuine Genus steps forward, inquiring if he has vented his anger. Carnage Kabuto reacts angrily, stating that it’s unjust for him to be locked up when he is the most potent creation of the House of Evolution.

Prof. Genus tells him that his actions are unchecked due to being out of control. However, the bug finds this idea amusing, as it doesn’t wish to be controlled. It considers itself a flawless creation and sees no one or thing above itself.

13. Flashy Flash

This exceptional character possesses a unique trait: he can move at an astonishing pace. He is incredibly swift and accurate. He’s an exceptional swordsman, and he will demonstrate his skills by blinding an octopus with a hundred eyes in a matter of seconds.

Overly proud, he harbors a strong dislike for Tatsumaki, who frequently belittles him and stands among the rare individuals who dare challenge him. Despite his good looks and popularity, he doesn’t consider status or rank and values real-life accomplishments instead.

12. SuperAlloy Darkshine

In the Heroes Association’s esteemed S-Class rankings, SuperAlloy Darkshine holds the position of number eleven. This exceptional hero is part of the Basement Assault Team. Many within the association regard him as one of the top melee fighters, sharing

Darkshine, a SuperAlloy, tends to maintain a tranquil demeanor. Moreover, he firmly believes that his impressive physique is always admired. His self-confidence is sky-high, leading him to regard himself as one of the heroes who should never be angered, joining the likes of King and Tornado in this esteemed category.

Despite this, SuperAlloy Darkshine could become irritated if one of his rivals exceeds their own limitations, appearing unimpressive in his opinion. In truth, SuperAlloy Darkshine embodies a self-centered hero more driven by the pursuit of recognition than challenges. What he truly yearns for is a tough battle that will push him to surpass himself and provide him with the satisfaction of victory.

I’m not accustomed to contemplating defeat, but that’s exactly what might happen when I face the Hero Hunter. The faster he seems to be growing in power, the more I find myself losing focus.

11. Genos

As a devoted disciple of Saitama, I am Genos – a cyborg equipped with an extraordinary collection of destructive weaponry. Prior to this transformation, I was just an ordinary human. Tragedy struck when my beloved family met their untimely end at the hands of a mysterious cyborg. Fortunately, I found refuge under the guidance of Professor Kidos, who graciously transformed me into the cyborg I am today.

Pursuing vengeance, he tracks down the trail left by a lethal cybernetic being, planning to destroy him and battle through various creatures to grow stronger. However, on a fateful day, he meets his match when he’s bested by Miss Mosquito in her Blood Queen persona.

As he prepared for self-destruct, Saitama miraculously rescued him, someone whose power Genos deeply respected. In the end, Genos ended up as Saitama’s disciple, despite the fact that Saitama couldn’t impart any knowledge about his immense strength to him. During his hero registration test, he scored an impressive 100 out of 100 points, placing him directly into the S-Class, where he was ranked 17th and last.

In a short span of time, he overtook Pri-Pri-Prisoner, finishing 16th and then 14th. His sensitivity towards his standing is evident as his objective, set by his master, is to rank among the top 10 in the S class.

10. Black Sperm

Black Sperm is a formidable, dragon-like sperm creature that serves as one of the high-ranking lieutenants in the Monster Association. Unlike other subordinates, Black Sperm despises being treated as such and seeks to prove himself by challenging Orochi, who styles himself as the King of Monsters, at every opportunity.

1) He’s known for his snarky and attention-grabbing behavior. If given an opportunity, he’d relish the prospect of competing against the other lieutenants of the Monster Association, provided he could emerge victorious. Beyond disliking boredom, Black Sperm detests being underestimated above all else.

When Atomic Samurai underestimated him, Black Sperm struck first and confidently clarified his opponent’s misunderstanding about his powers. He doesn’t hesitate to inform a child that he is on the verge of taking his life, as if it were a routine occurrence for him. It’s simply part of his pastime.

9. Silver Fang / Bang

Known as the strongest martial artist in existence, Silver Fang (his real name is Bang), is an elderly yet composed and contemplative individual possessing colossal strength. He oversees an ancient dojo that holds immense value for him, perched atop a mountain where he imparts his unique style of fighting, known as the “Rockbreaker Water Fist”.

The character from season 2, known as Garou, was his top pupil. However, his immense power and aggressive nature scared off other students, causing them to abandon the martial arts school. Beneath his clothes, Garou conceals an extremely muscular physique and is exceptionally agile.

At present, Charanko is his sole pupil. Not many are privy to Saitama’s real power, but he is one of them. He is associated with Bomb, who wields the Iron-Slicing Whirling Fist as a master.

8. Elder Centipede

The Colossal Arthropod known as Elder Centipede belongs to an elite league of monstrous insects, holding the rank of lieutenant within their association. He’s a formidable figure, confident and unyielding. Unlike Junior and Senior Centipedes, he doesn’t hesitate or show concern when his fellow centipedes are threatened or harmed.

Usually, he considers his adversaries as insignificant creatures given his immense strength. However, Elder Centipede has the ability to speak, but he’s not particularly chatty. His self-esteem can be shattered only when he is defeated, which happened on the day he was bested by Blast.

He’s harbored an unquenchable resentment towards Blast ever since that fateful day, and it sets him off every time the subject comes up in conversation. It appears that Elder Centipede became a part of the Monster Association driven by his thirst for vengeance.

7. Tatsumaki

As a cinephile, I recently watched a film that follows the journey of a 28-year-old protagonist who, despite appearing youthful due to her extraordinary telekinetic abilities, carries the weight of adulthood. Her powers are both a blessing and a curse; they make her formidable against adversaries, yet they’ve hindered her physical growth. This character often finds herself unappreciative towards her peers, but as the story unfolds, we see her grow, learn, and ultimately embrace her unique abilities to fight for what she believes in. A gripping tale of self-discovery, this movie is a must-watch for anyone who enjoys action, drama, and a touch of the supernatural.

His abilities are immense, capable of effortlessly leveling a city, halting incoming projectiles, causing catastrophic natural events, or even summoning meteor showers. Additionally, she possesses the ability to generate shields for self-protection and boasts other mystical powers, some of which remain unseen, as per Silver Fang’s account.

Due to her short fuse, she frequently resorts to cursing when responding to simple affirmative or negative responses from others.

6. Garō

Garō was expelled from the Rockbreaker Water Fist Dojo by his mentor Bang. He feels it’s unjust that only the heroes are praised for their victories, good looks, and admiration from citizens. He believes even villains deserve a chance at success.

He determined that he would become the most formidable among the monstrous creatures, defeating even the elite S-class heroes. Subsequently, he sought out these heroes for battle, growing more boastful after each victory.

Initially, he introduces ordinary heroes, followed by the entire longshoreman family, even the top-tier Master Longshoreman. Later, he confronts both Batman and the Elder Millipede.

In their encounter, it wasn’t a genuine battle between them, as after Garō landed an utterly ineffective strike on Saitama, the latter knocked him unconscious with a single blow. When Garō came to (surrounded by trash bags), he couldn’t recall anything. Known as “the human monster”, this is how their fight transpired.

5. Psykos-Orochi

Psychokos allows Orochi to infiltrate her body with his adhesive tissue. Yet, when she perceives his rapid growth in power over a short span, she is filled with fear. Orochi starts draining her energies, but she fights to stay awake.

Orochi informs her that, having made numerous sacrifices for her evolution, it’s now her turn to offer sacrifices. This angers Psykos, who asserts her dominance in their relationship by reminding him of this fact. As they attempt to unite, both Psykos and Orochi see a peculiar specter appear before them.

A colossal mass of brain cells materialized, granting Psykos extraordinary abilities to unite successfully. To Psykos, this entity was akin to a deity. Through her psychic prowess, she managed to outsmart Orochi during the merge, culminating in their transformation into a creature resembling an insectoid being.

4. Boros

In my perspective, Boros is an extraordinary extraterrestrial, a colossal galactic despot who traverses the cosmos in pursuit of a prophecy foretelling a formidable adversary to match his might. Upon touching down on Earth, he swiftly reduced city A to rubble within the blink of an eye, unleashing a torrent of devastation from his colossal warship.

Boros is a being who claims he surpasses everything and has the power to destroy a planet when enraged. He describes his species as a lifeform uniquely equipped to survive in the universe’s harshest conditions, excelling even in the most challenging situations. If not the strongest, he certainly ranks among the mightiest representatives of his kind.

In an epic battle, Saitama confronted Boros. Unfortunately, Saitama met his end during this fierce encounter. Interestingly, Boros is deep blue in hue, sporting only one eye. However, when he’s focused and ready to unleash his full potential, he transforms to a radiant white and surpasses the power of calm Saitama.

Despite Saitama barely tapping into his immense powers, this adversary has been the only one who hasn’t been instantly killed on their first encounter and managed to engage in a single battle against Saitama, albeit a lopsided fight where they were soundly defeated without much injury from the hero.

3. Blast

In the opinion of Sytch and the Little Emperor, this hero is the strongest within the entire Association. He’s a man with cropped hair, resembling Superman’s style, and sports a cape. The Little Emperor claims that he only manifests when he’s sung to specifically, and seldom responds to summons from the Heroes’ Association.

As the Phoenix man himself claimed, he engaged in a fierce battle with the Centipede’s elder and inflicted such severe damage that the elder was compelled to flee for survival, despite possessing formidable powers. Interestingly, though he hasn’t been featured in the web-comics, this character makes his debut in the manga in chapter 194.

His abilities remain largely undefined, yet it appears he possesses extraordinary physical strength, astonishing speed, vast knowledge, colossal size, and the capacity for instantaneous travel through space (teleportation).

2. Saitama

Saitama is an energetic, yet unremarkable young man who often battles enigmatic creatures in his quest to become an exceptional hero. His daily routine consists of running ten kilometers, doing one hundred push-ups, one hundred sit-ups, and one hundred squats each day.

Following an exhaustive training regime, Saitama observes two significant transformations: he’s become incredibly strong, able to vanquish foes with a single blow, and he’s bald now. His primary attack is the renowned “One Punch”, a seemingly ordinary punch capable of defeating immensely powerful adversaries such as the King of the Seas, Ashura Rhino, the King of the Underworld, a colossal meteorite, and numerous others.

When a single punch isn’t sufficient, he resorts to a rapid series of normal punches, often referred to as a “Normal Combo Punch.” This technique involves linking several individual punches together. In particularly challenging situations, he can enter “Serious Mode” and unleash powerful strikes known as “Strike super-worship” in the anime against exceptionally strong opponents. So far, this enhanced version has only been used once.

The force he wields is immense and surpasses that of any hero or villain we’ve previously faced.

1. God

According to Emperor Vanupieds, this deity or supreme being is what certain individuals consider as divine.

For the very first time, Morveduse calls upon a name said to be divine, as he shares that the lieutenants of the Monster’s Association appear so powerful they seem like beings personally crafted by the Creator himself. In the heat of the conflict, one such lieutenant, Vanupieds the Emperor, narrates his personal encounter with a being believed to be God, to Zombiman.

During the fight, Psykos found it challenging not to be fully consumed while trying to merge with Orochi. At this critical moment, they claim a colossal brain-like deity manifested before them. This divine entity is said to have bestowed upon Psykos an extraordinary energy power, enabling him to conquer Orochi and eventually complete the fusion process successfully.

After that point, she was given a task: to destroy the world by consuming it. Following his capture by Zombiman during the battles on the ruined monster’s nest, Emperor Vanupieds was interrogated.

Or:

From then on, her objective became global annihilation through absorption. After he was seized by Zombiman in the clashes atop the destroyed monster lair, Emperor Vanupieds underwent questioning.

Zombiman wants to know from whom his powers were obtained, since he believes the Heroes’ Association should be prepared to confront him as an adversary. However, before Emperor Vanupieds could provide a definitive response, a voice inside his mind commanded silence.
