It revolves around a man named Saitama, a man who is so powerful he can literally obliterate anything with a single punch. Because he is so powerful, Saitama has become bored and uninterested, lacking motivation to do anything. Despite wanting to have long and epic battles with his opponents, he finds himself mowing them down without even breaking a sweat.
He is sarcastic and impatient, doing things that are against our regular expectations of an anime protagonist and prioritising ridiculous things. He is accompanied by his ‘apprentice’ Genos, an extremely powerful android who is desperately trying to learn the secret and origin of Saitama’s amazing power. They are also accompanied by many heroes from an organisation known as the hero association, a collection heroes like the Justice League that are ranked based on their hero activity.
The show is full of jokes and satire, digging into and mocking well-known shows such as DBZ and Full-Metal Alchemist in a dead pool-like satirical way. This series is for everyone, from someone who has never watched anime before and wants to start with something light and funny, to long-time fans of the genre who find that it has become slightly burnt out. While so far it only consists of a single, 12 episode season alongside the manga series from which it was adapted, there are plans for an English dub and a second season of both the anime and the manga.
