Introduction
The anticipation surrounding the return of One Punch Man is palpable among fans, although some have expressed concerns over the previous season’s execution. Nonetheless, many are looking forward to the series’ exploration of one of its most riveting arcs: the Monster Association Arc.
This significant arc not only ramps up the stakes but also showcases a variety of characters in exhilarating battles and pivotal moments. Overall, the Monster Association Arc is poised to propel One Punch Man back into a prominent position within the anime landscape.
What Is The Monster Association Arc?

This arc marks the 15th and arguably the most extensive arc in the One Punch Man series, concluding the Human Monster Saga. Spanning nearly 100 chapters, it delves into the events leading up to and during the Hero Association’s raid on the Monster Association—a confrontation that has been building throughout the series. Though the forthcoming season will explore much of this arc, its preliminary events were hinted at toward the end of season two, notably with Sonic’s encounter involving a monster cell.
As Garou states, “The popular will win, the hated will lose; it’s such a tragedy. Then I won’t lose to anyone. I will become the strongest monster ever and change this scenario.”
At the core of the Monster Association Arc is the Hero Association’s targeted attack on a coalition of monsters threatening humanity. Following the Monster Association’s abduction of human hostages, numerous S-Class Heroes, alongside other capable warriors, are deployed to confront this dire new threat, leading to one of the most extensive and memorable battle sequences ever depicted in One Punch Man.

The subsequent chapters of the Monster Association Arc focus on dismantling the leadership of this formidable group of monsters. Under the command of King Orochi, other notable figures, known as cadres, include formidable entities such as Black S, Overgrown Rover, Elder Centipede, and Homeless Emperor. The fundamental belief within this organization is that if monsters can join forces to combat heroes, they will become an indomitable force. Their ultimate objective is to obliterate the Hero Association and foster a world dominated by monsters through any means, including hostage-taking and converting humans into monsters using Monster Cells.

Incredible Fight Scenes and Stellar Visuals

- The Monster Association Arc offers exhilarating battles that allow more than just Saitama to shine.
- Fans will witness the resolution of Garou’s compelling character journey.
For fans unacquainted with the manga, the upcoming arc promises numerous fight scenes that delve deeper into the capabilities of S-Class heroes. These intricately crafted battles were largely absent from the original web comic but provide crucial development for the heroes involved. Notable characters like Zombieman and Flashy Flash are poised for standout moments in the upcoming season.
Additionally, viewers can look forward to a fulfilling conclusion to Garou’s transformation arc. A spirited debate persists regarding which version— the webcomic or manga— delivers the superior narrative, with many favoring the webcomic’s storytelling and the manga’s artistic presentation. The anime adaptation aims to harmonize the strengths of both formats, though it is likely to adhere more closely to the manga’s pacing.
What Are Fans’ Concerns Regarding This Arc?
Issues with Pacing

Despite the excitement surrounding the Monster Association Arc, fans have expressed reservations regarding the pacing of the narrative. Stretching nearly 100 chapters, it surpasses the length of any previous arc, which may pose challenges for the anime adaptation. A carefully crafted pacing approach will be essential for delivering an enjoyable viewing experience.
As Saitama poignantly notes, “I’m just a guy who’s a hero for fun.”
The eagerly awaited Hero Association’s assault on the Monster Association stands as a highly anticipated event for fans of the anime. However, given some pre-existing criticisms of the arc, the upcoming season may face challenges in meeting expectations. Nonetheless, if executed with the same brilliance as the first season of One Punch Man, it promises to deliver an exceptional viewing experience.
