One Punch Man Season 3: Release Date, Trailer, Plot & Latest Updates

The long wait is nearly over, One Punch Man Season 3 is officially on its way. After years of speculation and fan anticipation, the next chapter in Saitama’s hilarious and action-packed journey has been confirmed to release in October 2025. With new villains, a larger-scale war, and some of the manga’s most intense arcs yet to be animated, Season 3 is poised to be a major turning point in the series.

Whether you’re a long-time fan or new to the world of One Punch Man, here’s everything you need to know about the season, from the release window to plot details, trailer breakdown, and where to stream the new episodes when they drop.

When Will the New Season Arrive?

The official release window for One Punch Man Season 3 is October 2025. Although the exact date hasn’t been announced yet, most fall anime shows usually start in the first week of October, so it’s very likely the new season will begin then.

It’s been a long wait. The first season came out in 2015 and was praised for its amazing animation and fresh take on superheroes. Season 2 arrived in 2019 with a different animation studio and got mixed reviews, but many fans still enjoyed the story and characters.

Now, more than six years later, excitement is getting higher than ever among fans. The trailer suggests better animation and a strong story ahead, so Season 3 could be a great comeback for the series.

What Will Happen in One Punch Man Season 3?

Season 3 will focus on the Monster Association Arc, one of the most exciting and action-packed parts of the One Punch Man manga. This storyline brings a full-scale war between the Hero Association and a powerful group of monsters called the Monster Association, led by the scary Monster King Orochi and the clever Gyoro-Gyoro.

The story continues from around Chapter 86 of the manga, after Saitama defeats the huge monster Elder Centipede. Genos is still trying to understand what it really means to be a hero and is frustrated by his own weaknesses. At the same time, Garou, the Hero Hunter, and one of the strongest character in the series, keeps slipping deeper into the role of a villain.

But the Monster Association is using him for their own plans. As Garou becomes stronger and faces more heroes, including Saitama and Genos, he starts to change and question his choices.

Season 3 is expected to cover about 40 to 50 chapters of the manga, possibly ending around Chapter 123. This would include the appearance of an important new villain named Psykos. Viewers can expect lots of thrilling fights, surprising team-ups, and deep questions about what it means to be a hero or a monster.

First Look at the Trailer

The first teaser trailer for One Punch Man Season 3 gives fans an early look at the action and drama coming ahead in the series. The trailer is short and focuses more on characters than on fight scenes, but it creates a serious tone with dark visuals, intense music, and quick looks at important characters.

We see Saitama, still as calm and careless as ever, walking with other heroes getting ready for battle. Heroes like Genos, Atomic Samurai, and Bang show up briefly, hinting that they will play big roles this season. The trailer ends with a powerful moment, Saitama saying he’s going to take down Garou when he will meet him.

The animation also looks much better than Season 2, which many fans criticized for its drop in quality. This new teaser shows cleaner, more detailed visuals and a movie-like style, giving fans hope for a strong return.

Where Will One Punch Man Season 3 Be Streaming?

Although it hasn’t been confirmed yet by the studio, it’s expected that One Punch Man Season 3 will be available on Crunchyroll, which is known for streaming popular anime. The previous seasons were also on Hulu, so it’s possible that both platforms will stream the new episodes when they come out.

For fans outside Japan, this means they’ll be able to watch the new episodes weekly. An English dub will probably be available shortly after the subbed version, just like with earlier seasons. Whether you prefer to watch it in Japanese or in English, fans worldwide should be able to enjoy the new season without much delay.
