One-Punch Man
For Saitama's gloriously anticlimactic heroics, Hulu and Netflix are the legal viewing options for One-Punch Man. This is superhero anime for anyone who likes spectacular fights but has grown tired of heroes needing a last-second power boost to survive every battle. Saitama begins at the finish line: he is so overwhelmingly strong that combat has stopped giving him any satisfaction. That reversal turns a familiar power fantasy into sharp comedy, because the loudest monsters and grandest declarations can barely interrupt his boredom. The action still lands with real force, while the humor comes from Saitama treating impossible danger like an annoying errand. Genos gives the story a useful counterweight. His intense drive and desire for revenge make Saitama's blank practicality even funnier, and their mismatched mentor-student dynamic keeps the series from becoming a string of identical punch lines. Watch it for the superhero parody, then stay for the contrast between absurd strength and painfully ordinary frustration.
About
Saitama chose hero work as a personal pursuit and trained until no enemy could stand against him. Achieving that dream produced an unexpected problem: victory is now automatic. Monsters may threaten the city and opponents may arrive convinced that they are unbeatable, but one hit from Saitama is enough to end the confrontation. Instead of feeling triumphant, he moves through each new crisis with the weary detachment of someone who already knows the result. His routine changes when he encounters Genos, a young cyborg consumed by a search for revenge. Genos is impressed by Saitama's strength and pushes himself into the role of student, whether his reluctant teacher feels qualified or interested. Their partnership places fierce ambition beside total apathy. Genos approaches every threat with deadly seriousness, while Saitama is still hoping to find an opponent who can make him feel challenged again. The story uses that gap for absurd comedy and explosive action, sending the pair against monsters and other powerful fighters while keeping its emotional focus on a hero whose greatest wish has become the source of his emptiness. It stays spoiler-light in its setup but quickly shows why Saitama and Genos are such a memorable duo.

Seasons & Watch Order
This is the first main season and the right place to begin, so you only need One-Punch Man to start the story. Watch it in episode order before moving to the second season. The related Road to Hero and Specials exist alongside the main series, but they are not a reason to postpone this starting point. Beginning here gives the central Saitama and Genos relationship its proper introduction and lets the parody establish its rules before later material continues it.
