There are two versions of the model, one simple and the other one with a shopping bag. 

Post Processing:

As i usually do with my prints I get rid of the supports, then i sand it, after this i applied two coats of primer(sanded it between coats). Once the model was smooth i start painting the model using acrylic paints and davinci fet brushes.

Description
Saitama is the main protagonist of One-Punch Man and so far the most powerful hero alive in the series. Saitama faces a self-imposed existential crisis, as he is now too powerful to gain any thrill from his deeds.

Initially just a hero for fun,he later registers into the Hero Association as a professional hero, currently B-Class Rank 7, and defends his home in Z-City from Mysterious Beings. Under the Hero Association, he is given the name Caped Baldy 

Saitama is a bald, ordinary-looking man with a thin, but well-built physique, and is of average height and weight. Saitama initially had spiky, black hair, but 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. Saitama also has brown eyes that are represented as dots.

So far, no enemy has been able to injure him in any way, and almost no enemy is even able to survive from a single earnest punch from him. A few enemies have survived punches from him, such as any human he has struck (which he was likely holding back against) and Boros, whom Saitama empathized with and held back against so as to give himself and Boros a satisfying and stimulating fight. Saitama's only power is that his body is far beyond human limits, allowing him to achieve astounding physical feats. His strength is so great that it vastly eclipses even artificial beings designed or bred specifically for superhuman combat, such as mechanical beings or the mutated warriors from the House of Evolution. Since no enemies have posed any real challenge to Saitama yet, the upper bound of his strength is likely even higher than it currently appears. While his power is only limited to heightened human traits - Saitama cannot fly, fire energy blasts, or perform any supernatural feats - his superhuman abilities more than makes up for the lack of variety in his powers.

The origin of Saitama's immense strength is mysterious and unclear. Although he tells everyone he got his incredible power through mere physical training, no one believes him at all. According to Saitama, after a year and a half of 100 daily push-ups, sit-ups, and squats, plus 10 km daily running, he had achieved some level of superhuman strength. This training was apparently so intense for Saitama that he at times felt he might die, and claims that it is what caused all of his hair to suddenly and eventually fall out. He apparently continued his training for another year and a half before beginning his hero career.
