17. Atomic Samurai

17. Atomic Samurai Atomic Samurai is the strongest samurai in the series, he possesses power beyond our comprehension. He can cut through boulders and is also known to destroy entire skyscrapers only using his blade. He isn’t the only one in the series to wield the blade, but he surely is the only one who has the most skills in sword fighting. He easily could’ve been in the top ten but then I realized that atomic samurai only has one power, fighting with his sword. Well, yes he is capable of fighting without his sword. He is a samurai after all, but he won’t be as effective as he was with the sword. So it was a tough call.

16. Child Emperor

16. Child Emperor Child Emperor is the youngest member of the Hero Association, but don’t take him lightly, because you know what they say, big things come in small packages. Although being only 10 years, and having no physical strength, he still makes it on this list because of his superintelligence. In fact, he is one of the smartest people on earth in the OPM universe. Also besides this, he has many inventions at his disposal which can turn the tide of any battle in his direction. He also possesses a mech suit which helps him in hard battles. Still being book smart isn’t going to win you every battle, if someone manages to turn off all the gadgets that he possesses, Child Emperor quickly becomes useless, as he has no physical strength whatsoever. Hence his low ranking on the list.

15. Zombie Man

15. Zombie Man Next up on the list is Zombie Man, his name is based on his capabilities, he’s a walking zombie, no one can kill. Who can be stronger than the man who can regenerate any part of his body? Zombie Man has such great regeneration that even Deadpool and Wolverine would be jealous, this unique ability of his makes him almost immortal. He is known to regenerate even the deadliest blows ever dealt with him. Zombie Man is an S-class hero so you know he’s serious about his work and packs a punch. In addition to Zombie Man’s regeneration, he also has excellent stamina and endurance, he could fight for days without getting tired, this alone is enough for us to give him a spot on the list.

14. Mosquito Girl

14. Mosquito Girl Mosquito girl is a creation of Dr. Genus, she’s a mutant with unique abilities resembling that of a mosquito. As the name implies, she’s a human-mosquito hybrid, which doesn’t seem like a good combination because mosquitoes are known to be weak. But she’s the total opposite of this, she has superhuman strength and durability. So in theory she could take on any S class hero from the hero association. With her hybrid nature come various other mosquito-related abilities, the most interesting one being the blood-sucking. Whenever she drinks blood she transforms into an even more menacing-looking beast with more power. In this form, she starts to wreak more havoc than before and becomes even more difficult to beat. She’s a force to be reckoned with and hence deserves a spot on this list.

13. Speedo-o-sound Sonic

13. Speedo-o-sound Sonic What does every top shonen need? A rival to our main character who will push him past his limits to achieve greatness. But Saitama already is the strongest, so what purpose does Sonic have? Nothing, he’s a self-declared rival of Saitama, and kid you not he is aware of the power that Saitama has. And he still tries to beat Saitama, we have to appreciate him for that. Sonic is a former member of the 44th graduation class of the ninja village. As his name suggests he is super fast, faster than light some might say. He can move so fast that he becomes invisible to the naked eye, and not just his super speed, Sonic is believed to have superhuman strength too. Combine this with his combat skills with his shinobi weapons and he easily is one of the most deadly villains in the series.

12. Metal Knight Dr. Bofoi also known as Meta Knight is an S-class hero, he has built himself an arsenal of super robots which can take on any villain. Many don’t consider him strong as he isn’t the one who’s fighting but his robots, well the same could be said about Tony Stark, so let’s just focus on his robot’s capabilities. Metal knight looks menacing, to say the least, it is a large chunk of metal that can fly and shoot missiles from its back. Not only missiles, but it also has an arsenal of weaponry stored inside of it which can be used to deal with any foe. If that wasn’t enough, it also possesses super strength and endurance, its energy also seems to be unlimited, and it can fight for a long time without needing a recharge.

If he was anything like what his name suggests, he could’ve been really helpful in this pandemic. Anyways, Vaccine Man is a mysterious being who was supposedly born from the industrial pollution that humanity has caused. Mother nature got furious and from her wrath, she gave birth to Vaccine Man. He wants to wipe out humanity and save the earth from further pollution. To carry out his work, Vaccine man has various abilities at his disposal like transforming into a beast!.

10. Carnage Kabuto

Carnage Kabuto Another mutant by Dr. Genus made it on this list, this time the strongest one of them all, Carnage Kabuto is undoubtedly the strongest creation of Dr. Genus and his organization. Carnage Kabuto looks like a massive hunk of meat with ridiculous strength and speed that even top heroes can’t match. This villain is so powerful that he is being used as a scale to rank how strong other villains are. The heroes train against this villain’s simulation to get better and stronger. Carnage Kabuto is the most perfect creation of Dr. Genus. That speaks volumes about this beast of a villain. If you want carnage, call this guy he surely knows how to wreak havoc.

9. Flashy Flash

9. Flashy Flash The name of this hero perfectly matches his personality and his abilities. Flashy Flash is the most powerful hero in the S class with immense strength and crazy sword skills. Combine these superhuman powers with his crazy fast speed and you’ve got yourself a hero which can kill an opponent in one-tenth of a second. In fact, he moves so damn fast that he leaves shock waves whenever he moves, these shock waves are similar to the sonic booms that the planes make when they surpass the speed of sound! He is faster than Speed-o-sonic and can cut boulders with precision using his blade. This fast speed would’ve been useless if he hadn’t had superhuman reflexes too. If this description of Flashy Flash doesn’t send chills down villain’s bodies we don’t know what would.

7. SuperAlloy Darkshine

7. SuperAlloy Darkshine The One punch man anime arguably has one of the coolest looking characters, in addition to this they also have really weird and wacky names, but I’m not here to complain because I like them all! Superalloy Darkshine is a type of hero who will get you motivated to hit the gym and start lifting the weights. No seriously, this guy literally got strong because of his sheer hard work and determination, no magic, no nuclear radiation, no spider biting him to become a hero. He can take on any villain with ease and defeat them too. SuperAlloy has such thick muscle that they deflect almost anything you throw at them.

6. Tornado Of Terror

6. Tornado Of Terror Tatsumaki aka. tornado of terror is undoubtedly the strongest psychic the one punch man universe has ever seen. Judging her by her Childlike petite stature is the worst mistake that anyone makes, despite being fairly small in size and having almost zero physical strength, Tatsumaki still manages to scare off any villains who try to cause harm. Her powers include her psychic abilities, harnessing them she can do almost anything. Other heroes and monsters are afraid of her as she possesses the power to level an entire thriving city just by using her mind. Her powers sound scary and almost God-like, it’s a good thing she’s on the side of heroes and not the other way round. She currently is the second-ranked hero in the S-class of the hero association!

5. Genos

5. Genos This entry may be controversial as many regard Tatsumaki as more powerful than Genos, but hear me out, you might change your mind. Genos is a beloved character and many regard him as the strongest hero despite his rank being lower than the Tornado of terror. Genos is a cyborg who has all the powers any hero in the S-class may have. His strength is superhuman, his endurance and stamina are some of the best in the series and his fighting skills make him even deadlier. Along with these physical abilities, Genos also possesses an arsenal of weaponry at his disposal which he uses in combat. He is a beast when it comes to battling villains! Now the reason why he is higher on the list is because of his cyborg nature, you see Genos’s cyborg body can be upgraded at any time. His new G4 upgrades made him even more overpowered than he was before, due to which he can now take on any enemy which threatens him no matter how great his/her power is. If Genos gets badly injured or his limbs become useless, he can always fix them as he is a cyborg after all. This gives him an edge in battle which other heroes don’t have, he can fight without worrying about damaging his body, in that sense he is immortal. The only way of killing Genos will be by vaporizing him into atoms! His backstory isn’t that interesting as Saitama has mentioned so we won’t dive deeper into it.

4. Garou

3. Garou At number 3 we have the former student of Silver Fang himself. Garou is a martial art prodigy who became too powerful and went on a rampage due to which he was expelled from the Dojo. He decided to go his way when he realized there was nothing more he could learn from Bang. He possesses almost superhuman strength and stamina, in combination with his unmatched martial arts skills, this guy is a force to be reckoned with. He hates both the heroes and the monsters, but he seems to be fascinated by monsters for some reason. Due to his unprecedented power the hero association is terrified of him, he’s only human and was able to wreak so much havoc, imagine what he will do if he gets a power upgrade!

3. Boros

4. Boros Now remember one thing, One Punch Man is a satire on the shonen genre and Saitama is the benevolent God that the creator has blessed us with. Boros was defeated by Saitama, yes, but you have to take into consideration the satirical nature of the show which makes Saitama overpowered. Boros was hyped as the final boss, the Thanos of the series if you may. But he wasn’t defeated easily, Saitama had to struggle, a little bit, but even that much is a lot. Saitama barely tries to win a fight as he is so overpowered. Due to this Boros is in third place on this list.
