List of One-Punch Man characters
The Japanese manga series "One-Punch Man" contains a number of fictional characters created by One and illustrated by Yusuke Murata. The series follows a superhero named Saitama and his disciple Genos who join the Hero Association so they can be recognized as such when they fight various monsters and villains. The Hero Association ranks all of its members by a Class and a ranking within that class. Characters listed are ones noted by the author in the manga profiles, ones that were highlighted in the anime character list, and ones that recur over  several story arcs. Main characters. Saitama. The title character, Saitama (サイタマ), is a bald-headed 25-year-old man who is bored of fighting because he is effortlessly able to defeat enemies with a single punch. He lives in an apartment in City Z. Three years prior to the start of the series, when he still had hair, Saitama was job hunting when he defeated the powerful supervillain Crablante that attempted to kill a child with his buttocks on his chin. Saitama says he became a hero "for the fun of it". His abilities mainly consist of physical abilities magnified  to an immeasurable degree: strength is the true power of Saitama, with speed, stamina, and durability being mere side powers. He attributes this to a daily training regimen (100 push-ups, 100 sit-ups, 100 squats, a 10 km run, eating healthy food, and not using the air conditioner or heater to reinforce his mental fortitude.) (He also mentions training even when his body was wounded and made strange cracking sounds). However, he seems to become stronger when he pushes himself to his limits (three years of that transformed him into what he is today) Early in the series, he  picks up a disciple and roommate Genos. Though he had broken all the physical records in the Hero entrance exam by huge margins, Saitama enters the Hero Association with a score of 71, giving him one of the lowest ranks in the Hero Association. This is due to his miserable performance on the mental exam. He soon goes up the ranks by performing many deeds, although many of his efforts are not recognized because of collateral damage or higher-tiered superheroes receiving more credit. These include defeating the raging ninja supervillain/assassin known as Speed-o’-Sound Sonic and destroying a  meteor similar to the meteor that made the dinosaurs go extinct with a single punch. As of the current arc of the webcomic by ONE, he is A-Class rank 39. He does not mind letting others have the recognition though, as demonstrated in his actions following the fight against the Deep Sea King. In the Dark Matter Thieves' story arc, he is unfazed by the telekinesis of a powerful esper, further displaying his resistance. This arc was also one of the only times he has used his "serious punch", defeating the world-conquering leader of the aliens, Lord Boros , before he could use his Roaring Star Cannon attack. Through various circumstances, he forms friendships with Mumen Rider, Bang, King, Genos, and Blizzard. His superhero name in the association is . Saitama is voiced by Makoto Furukawa in the Japanese version and by Max Mittelman in the English dub. Genos. is a 19-year-old cyborg who becomes Saitama's disciple after bearing witness to Saitama's easy victory over Mosquito Girl. Four years prior to the start of the storyline, his family was killed by a rampaging cyborg known as Mad Cyborg. Genos was nearly killed in the attack and  his body was destroyed so, to keep him alive to stop the Mad Cyborg for justice, a scientist named Dr. Kuseno took Genos in and modified his body to make him a cyborg with destructive capabilities. However, Genos remains steadfastly convinced that justice demanded vengeance against and destruction of the cyborg. His perfect score on the entrance exam for the Hero Association places him in S-Class, but he still considers Saitama to be his master and goes with him whenever he is not summoned to other missions. Saitama often has to save him, as Genos' headstrong personality causes him  to jump into action without thinking. He lives with Saitama after offering a sizable down payment for his share of the rent. His superhero name in the Hero Association is Genos is voiced by Kaito Ishikawa in the Japanese version and by Zach Aguilar in the English dub. Hero Association. The is a superhero organization founded by the multi-millionaire Agoni in order to fight monsters, criminals, and various threats. It uses a Hero Registry to indicate which characters are recognized as professional heroes, with anyone who is not registered to be considered "a pervy freak who spouts irresponsible nonsense ." Agoni created the association after his grandson was saved from the monster Crablante by an unknown bystander (who turns out to be Saitama). It is also financed by donations from citizens. The association is made up of four tiers from the lowest C-Class to the highest S-Class. The heroes within each class are ranked numerically, with the highest rank 1 of each class being eligible to advance to the next tier if they so desire. New heroes must take an exam in which 50% is a physical test, and the other 50% is a written exam and an  essay. A passing grade would be 70% or higher and directly placed in a class from 70% being barely C-class to 100% being eligible for S-class. They are then placed at the lowest ranking for that tier. Heroes can ascend or descend in their rankings depending on their deeds; C-Class heroes who are inactive for a week are dropped from the Registry. S-Class Superheroes. S-Class is the highest hero rank in the Hero Association. Those who have gotten a perfect score on the entrance exam, as well as the top candidate from A-Class, are  eligible to enter this class.

Terrible Tornado and Sitch were one of the first people to know who he is and what he looks like. Blast once fought Centichoro, a powerful, giant centipede, and brought it to the brink of death. He also fought the Ninja Village Leader at one point, ending with the Leader being rendered comatose for 15 years. He has saved Amai Mask and became his idol. During Hero Association's assault on Monster Association's headquarter in the present, Blast finally resurfaces to take a God's cube which  Saitama found at a rubbling Monster Association's underground location where the latter is trapped alongside Flashy Flash and a one-eyed female monster Manako. Blast helps two heroes and the small monster out of the rubble. When God attempt to corrupt Tornado through mimicking Blast’s appearance, the latter is able to resist it, just as the real Blast’s nearby presence, which cause God to retreat.

In the battle with the Dark Matter Thieves, she easily turns around a multitude of shells shot from a large alien ship back onto itself, dealing tremendous damage. Other espers are generally dwarfed  by her overpowering telekinesis. She has a short temper and is often scolding people for their incompetence.

His sole student is Charanko as he had a former disciple named Garo who beat down his other students including Sourface until they quit, and Bang was too late to stop Garo from learning a forbidden knowledge of Bang's former fighting style. The incident of Garo walking a similar path as Bang had is a painful memory for the latter and as a result, he constantly looks for new disciples to pass on his martial arts; Charanko is fairly incompetent, after all.
