Three years prior to the start of the series, when he had hair, Saitama was applying for jobs as a salaryman, when he defeats a crab-like monster that attempted to kill a child.Ch. 2 Saitima says he became a hero "for the fun of it".Ch. 5 His abilities mainly consist of normal human physical abilities (he does not have the ability to fly or project energy) magnified to an immeasurable degree: speed, strength, stamina, and durability, which he attributes to a daily training regimen of 100 push-ups, 100 sit-ups, 100 squats, a 10 km run, eating right, and not using the air conditioner or heater to reinforce his mental fortitude.Ch. 11 His power eventually saves Genos from the villain Mosquito Girl, who declares himself as Saitama's disciple. Though Saitama often finds Genos annoying, the eventually form a bond. Genos is the first person to expose Saitama to the Hero Association, where he can officially receive recognition for his hero work.
Though he had broken all the physical records in the hero entrance exam by huge margins, Saitama enters the Hero Association in the lowest C-Class rank due to his miserable performance on the written exam.Ch. 16 He soon advances from performing superheroic deeds, although many of his efforts are not fully recognized because of collateral damage or higher-tiered superheroes receiving more credit. He does not mind letting others have the recognition though, as demonstrated in his actions following the fight against the Deep Sea King. His assist in the fight against Deep Sea King enabled him to advanced to B-Class thanks to a commendation by top C-Class hero Mumen Rider.Ch. 27-29 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 where he has used his "serious punch", defeating the world-conquering leader of the aliens, Boros. Through various circumstances, he forms friendships with Mumen Rider, Bang, King, and Blizzard. His superhero name in the association is Bald Cape (ハゲマント Hagemanto, Anime: Caped Baldy).Ch. 45

Genos was nearly killed in the attack and his body was destroyed so, to keep him alive to stop the rampaging 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.Ch. 7 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.Vol. 3-4 Saitama often ends up saving him, as Genos' headstrong personality causes him to jump into action without thinking.

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.Ch. 15 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.Vol. 4 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.Ch. 16 They are then placed at the lowest ranking for that tier.Ch. 16 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.Vol. 3
