Is One Punch Man season 2 released?

Yes — season 2 premiered in Japan on April 9, 2019 (Anime News Network (anime database)) and ran for 12 episodes through June 25, 2019. The first episode of the season is titled “Return of the Hero” (Rotten Tomatoes (review aggregator)).

When did One Punch Man season 2 air?

  • Episode 1: April 10, 2019 (Anime News Network (anime database))
  • Episodes 8–11: May 30 through June 27, 2019 (Anime News Network (anime database))
  • English dub aired later on October 12, 2019 (Anime News Network (anime database))

How many episodes does season 2 have?

Season 2 contains exactly 12 episodes (Hulu (streaming platform)). That’s three fewer than season 1, which had 12 episodes plus a 13th OVA. The shorter run meant the Monster Association arc had to be heavily condensed.

Bottom line: Season 2’s 12-episode count forced a compressed adaptation of the manga’s longest story arc. For anime-only viewers, the result is a faster pace; for manga readers, key moments felt rushed.

The implication: the episode cap directly shaped the creative decisions that followed.

Was One Punch Man season 2 on Netflix?

Yes, but not everywhere. Anime News Network (anime database) lists Netflix as one streaming entry for season 2, indicating availability in at least some regions or time windows. The exact list of countries is not publicly documented.

Which regions have season 2 on Netflix?

  • Netflix availability is confirmed in select regions (Anime News Network (anime database))
  • No comprehensive regional list exists from the publisher

Can I stream season 2 on other platforms?

Bottom line: US viewers get Hulu as the most reliable option. Netflix coverage is spotty — don’t rely on it unless you’ve checked your local library. The streaming fragmentation means many fans still turn to DVD or digital purchase.

The catch: fragmented streaming rights force viewers to verify availability before committing to a platform.

Is Saitama season 3 coming?

Yes — season 3 was officially announced in August 2022 (Wikipedia (episode guide)). No exact release date has been confirmed yet.

When will season 3 be released?

No official date has been set. Given the two-year gap between season 2 and the announcement, plus ongoing production, a 2024 or 2025 release window is plausible but unconfirmed.

What is the status of season 3?

  • Announced: August 2022 (Wikipedia (episode guide))
  • Studio: not yet named – no official confirmation of J.C.Staff returning or a new studio
What to watch

The studio decision for season 3 will shape the entire arc. If J.C.Staff returns, expect the same visual style. If a different studio takes over — as happened between season 1 (Madhouse) and 2 (J.C.Staff) — expect another debate about animation quality.

The pattern: studio selection remains the single biggest unknown for season 3’s reception.

Did Saitama adopt black sperm?

In the original webcomic by ONE, Saitama keeps a small Black Sperm as a pet after the Monster Association battle (Wikipedia (episode guide)). This event has not been depicted in the anime — season 2 ends before that arc.

What happened to Black Sperm after the Monster Association arc?

The webcomic shows a tiny Black Sperm living peacefully with Saitama in his apartment. The manga adaptation by Yusuke Murata has not yet reached that point. The anime season 2 covers only the beginning of the Monster Association story.

Is Black Sperm still alive in the manga?

In the manga, Black Sperm is defeated but not killed. The webcomic reveals his survival as a miniature version. Fans of the anime will likely see this resolved if season 3 adapts the rest of the Monster Association arc.

What this means: webcomic readers know the punchline, but anime-only viewers are still waiting for the reveal.

Who is S rank no. 1?

The top S-Class hero is Blast (Anime News Network (anime database)). He has minimal screen time in season 2 — a brief silhouette appearance and a mention during the Meteor incident.

What is Blast’s role in the Hero Association?

  • Rank 1 among S-Class heroes (Anime News Network (anime database))
  • Almost never seen — mysterious figure who operates from the shadows

Has Blast appeared in the anime?

A silhouette appears in season 2 episode 8 during a Hero Association meeting. His full design and abilities are revealed later in the manga and webcomic, but not in season 2.

Bottom line: Season 2 treats Blast as a looming mystery. For newcomers, the lack of screen time may feel anticlimactic, but the payoff is reserved for future arcs — likely season 3 or 4.

The catch: Blast’s absence is intentional — his reveal is a long-term investment, not a missed opportunity.

Editor’s note

Season 2 is a transitional season — it introduces the Monster Association arc, swaps studios, and sets up major events for season 3. The production turmoil (studio change, director switch) directly impacted animation style, which remains the most debated topic among fans.

Does Saitama appear in every episode of season 2?

Yes, Saitama appears in all 12 episodes, though not always in action — many episodes focus on side characters.

The implication for fans waiting for season 3 is clear: temper expectations around a release date, but rest assured the Monster Association arc — when it finally arrives — will justify the wait.
