Start at episode 1, and know which studio made which season
One-Punch Man streams in the US on Hulu, not Crunchyroll — the assumption that trips people up most often. Hulu’s own series page carries all three seasons, sub and dub, and counts them as 72 entries because each episode is listed twice.
The three seasons were made by different studios, and you can hear the argument about it in any comment section. Madhouse animated the 2015 season; J.C.Staff took over for season 2 in 2019 and stayed for season 3, which began on October 12, 2025 after a six-year gap. We covered the animation controversy that followed when the season-3 footage landed.
One thing the episode table above will not tell you: season 3 is not finished. The twelve episodes listed are its first cours, and a second cours is set for 2027, so the Monster Association raid is left mid-fight. Everything before it is complete, and season 1 is a self-contained twelve-episode arc with a real climax — a fair place to stop if you only want to sample the show.
