One Punch-Man (ワンパンマン WanPan-Man) is a Japanese webcomic and manga series created by ONE. The webcomic started in July 2009, with more than 10 million total views and 20,000 hits per day. Sheuisha’s Young Jump Next picked up the series, as well as commissioned Yusuke Murata, (known for Eyeshield 21) to draw the series with the original writer, ONE.
Saitama (サイタマ, Saitama) is the main protagonist of OnePunch-Man and the most powerful hero alive. Saitama faces a self-imposed existential crisis, as he is now too powerful to gain any thrill from his deeds.
He registered with the Hero Association as a C-Class and eventually made a big leap to become a B-Class Superhero and is tasked to defend Z-City against Mysterious Beings. Under the Hero Association, he is given the name Caped Baldy (ハゲマント, Hagemanto).
Saitama is a bald, ordinary looking man with a thin, but well-built physique and of average height and weight. He claims to have lost all of his hair suddenly and prematurely as a result of the toll taken on his body by his intense hero training. Three years before the story line, Saitama had spiky, black hair and brown eyes that are usually represented by dots.
Saitama is usually deliberately drawn in a simpler style than all the other characters, with an elliptical shaped head and only a simple mouth and eyes. When drawn in a more serious style with more detail, Saitama is revealed to have sharp features, dangerous looking eyes, and a chiseled musculature. Even his posture undergoes a metamorphosis, with a slack posture and sloping elbows when lax, while possessing a straightened posture and squared shoulders when serious. His costume is a plain yellow jumpsuit with a short zipper at the collar and a belt. The costume is finished out by a red ensemble of boots, gloves and a white or red cape.
Genos (ジェノス, Jenosu), is a 19 year old cyborg and the disciple of Saitama. He is always aiming to become stronger and fights for justice. Under the Hero Association, he is given the name Demon Cyborg (鬼サイボーグ, Oni Saibōgu) and is registered as an S-Class hero, at rank 14.
Genos has an entirely mechanical body in the model of a handsome young man. His face and ears look like that of a normal human, made of an artificial skin material, and his eyes have black sclera with yellow irises. He has spiky blond hair. His eyebrows are usually portrayed as blond, but in the anime they are brown. He also has pierced ears. Genos wears normal street clothes and sleeveless tops and hoodies in order to allow his arms to transform without hassle. He has been shown to have many different sets of arms, with varying abilities and strengths. Notable examples of his various «arms» are those he used in his sparring match against Saitama and the arms he equipped to combat the meteor. Sometimes the arm sets he uses create a metal framing around his face, like those he used against the meteor and the Sea King.
The story takes place in the fictional Japanese metropolis of City Z. The world is full of strange monsters that mysteriously appear and cause disasters. Saitama, the protagonist, is an incredibly powerful hero who can easily defeat the monsters or other villains with a single punch. However, due to his overwhelming strength, Saitama has become bored with his powers and is constantly trying to find stronger opponents who can present a challenge to him.
On his adventures, he meets new friends, enemies, and his own disciple, the cyborg Genos, and joins the Heroes Association in order to gain official recognition as a hero. Despite defeating many strong monsters that even the Heroes Association’s top members are unable to defeat, Saitama struggles to gain respect. Most people look down on him due to his plain physical appearance, and some accuse him of being a counterfeit hero. Only a small number of individuals recognize his incredible talent and humility towards others.
