One Punch Man: 8 Strongest Heroes In The Series, Ranked

One Punch Man stands out from other shonen anime thanks to what is quite possibly the most broken power scaling of any shonen franchise. Dealing with cosmic threats that can destroy entire cities on a whim, OPM is filled with powerful villains who must be kept in check by even stronger heroes.

This is where the Hero Association comes in, as the main organization that employs heroes to save the world. Among them, one can find some of One Punch Man's strongest characters. The strongest heroes in One Punch Man are simply on another level, capable of overpowering even the most OP characters from other anime.

Honorable Mention: King May Be The Strongest Of Them All

Rank: S-Class, Rank 5

In the entire One Punch Man series, there are very few characters whose names inspire as much fear and awe as King – the fifth-highest ranked hero in the Hero Association and is also called the 'Strongest Man on Earth'. As fans of the series know, King is nothing more than a regular human being with no discernable powers aside from his loud heartbeat.

A common theory among the fandom is that King's true power is immense luck, due to which he has survived encounters against even the most terrifying monsters in the series. Most of the time, Saitama just happens to be around to thwart any potential threat. Other times, such as when he 'used' his strongest attack, the Ultimate Hellfire Burst Wave Motion Cannon, things just end up working out in his favor through other means, which may make him the actual strongest in the series.

Flashy Flash Is One Of The Fastest Heroes in One Punch Man

Rank: S-Class, Rank 10

Flashy Flash made his name within the ranks of the Hero Association thanks to the impossible speeds he can reach in battle, making him appear more as a flash of light than anything else. He has displayed speeds far greater than many of the characters in the series, as he has even been described as being able to travel almost as fast as light itself.

On top of this, Flashy Flash is quite adept with a blade and has trained as an assassin for much of his early life, which gives him many more skills in battle. He would definitely have ranked higher up, but there are quite a few characters who not only overpower him, but also outspeed him, which is quite telling since his entire deal is being faster than everyone else.

Bang And Bomb Are Unparalleled Martial Artists

Incredibly Powerful Fighters

​​​

One of the surefire ways to get stronger in the One Punch Man series is through proficiency in Martial Arts, which is how villains like Garou were able to reach the highest levels of power. Among those who are practitioners, none are greater than Bang and Bomb, the two legendary brothers whose fabled strength has come forth due to their expertise as fighters.

While both are far past their primes and Bang has even retired from the Hero Association, they serve an indispensable role as heroes against the forces who seek to destroy the world. Bang, specifically, was able to go toe-to-toe with Monster Garou during the Monster Association arc despite being his senior by decades, and almost even defeated the villain.

Genos Has Way Too Many Tools In His Arsenal

Rank: S-Class, Rank 11

Although he is ranked lower than Flashy Flash, most fans tend to put Genos as the stronger of the two, simply due to the many tools he has at his disposal, as well as his firepower being some of the most destructive in the entire series. In the Monster Association arc, Genos was able to fight against some of the strongest monsters.

Due to his nature as a cyborg, Genos can be frequently augmented or improved, and his latest form makes him one of the Hero Association's most valuable assets. With blinding speed, immense strength, and unparalleled destructive output, Genos is definitely one of the series' strongest heroes.

Atomic Samurai Is One Of The Greatest Heroes Alive

Rank: S-Class, Rank 3

Atomic Samurai is widely regarded as the strongest and most skillful swordsman in One Punch Man due to his mastery of the blade. With his talents, he has been shown to cut things down to the atomic level with his blade, making him so powerful that Superalloy Darkshine said that if Garou had fought him before breaking his limiter, Atomic Samurai would have easily cut him down.

Atomic Samurai's strength and speed have allowed him to cut down very durable and powerful opponents by releasing hundreds of cuts in seconds. Nowadays, he has risen to S-Class, Rank 3 due to his acquisition of the Sun Blade, using which all of his stats have been increased by many degrees. Through this sword, he has become an unparalleled swordsman.

Tatsumaki Is The Series' Greatest Psychic

Rank: S-Class, Rank 2

Many fans tend to place Tatsumaki at the top of the S-Class due to the insane feats she has displayed throughout the series. As the strongest psychic in One Punch Man, Tatsumaki's telekinetic powers are able to move entire mountains and structures that are the size of full islands.

The greatest showing of her power was when she went against the fused version of Psykos and Orochi, who itself was one of the most dangerous and powerful psychics in the world. Though she did have some invaluable help from Genos, Tatsumaki proved her place at the top of the Hero Association by defeating this powerful villain.

Blast Is The Highest Ranked Hero

Rank: S-Class, Rank 1

As the man who holds the position of the highest ranked hero in the entire association, it's no secret that Blast's power is some of the greatest ever seen in the series. Though his showings have been brief, his ability to manipulate space itself is something that not even the strongest foes can avoid.

Blast briefly used his Gravity Knuckle on Cosmic Garou, who even noted its power and later adopted it into his own move set. Aside from this, Blast's speed was something even Flashy Flash couldn't react to, and his ability to create Black Holes was so great that he managed to transport the entire Hero Association HQ away from danger, which definitely makes him deserving of Rank 1.

Saitama Is The Strongest Being In The Entire Franchise

Rank: A-Class, Rank 39

In a franchise filled with impossibly powerful monsters who can move faster than the speed of light or heroes who can easily destroy buildings, the most powerful figure among them is someone who just wanted to be a hero for fun. Saitama is so strong that his fights typically end with just a single punch.

He broke his limiter through his intense training regime, which has essentially allowed him to never stop growing in power. Saitama is such a broken character that he can sneeze away entire planets, grab space-distorting portals as if they are Frisbees, and fart with such intensity that he gets propelled faster than the speed of light. These are just some of the reasons why so many believe Saitama to be the strongest character in fiction.
