Season 1 was almost perfectly formed from start to finish, giving Season 2 the unenviable task of wringing more juice out of what is essentially a single note joke: A hero whose central conflict is that he's too successful. Its ludicrously overpowered titular hero pokes fun at both shonen and superhero archetypes, giving One-Punch Man huge cross-genre appeal for anime and comic book aficionados alike. This feat was achieved through sharp, witty writing, crisp and fluid animation, a catchy, anthemic theme song and, most importantly, a unique spin on tried (and tired) tropes. One-Punch Man's debut season made the show one of the breakout anime hits of 2015.
