The long-awaited One Punch Man Season 3 is officially set to release in October 2025, and fans can’t wait to see what’s next for Saitama and the gang. With the previous seasons covering the Hero Association saga, many are wondering which arc the new season will adapt and whether the long-anticipated battle between Saitama and Garou will finally take place. Here’s everything we know so far.
Which Arc Will One Punch Man Season 3 Cover?
Season 3 of One Punch Man will primarily adapt the Monster Association Arc, which is one of the longest and most action-packed storylines in the manga. This arc dives deep into the chaos caused by the monstrous organization as they declare war against the Hero Association. Expect to see intense battles, major character development, and jaw-dropping animation as heroes and villains collide in an all-out war.
Some of the key moments this arc will cover include:
- The full-scale invasion of the Hero Association by the Monster Association.
- The rise of new and formidable monsters, including Orochi and Psykos.
- The development of key S-Class heroes such as Flashy Flash, Atomic Samurai, and Tatsumaki.
- Garou’s evolution as he continues his path from rogue martial artist to something much more dangerous.
Will We See Saitama vs Garou in Season 3?
One of the biggest questions fans have is whether we’ll finally witness the highly-anticipated showdown between Saitama and Garou. In the manga, Garou undergoes multiple transformations throughout the Monster Association Arc, eventually reaching a level where he can challenge even the strongest heroes.
While the anime might not complete the entire arc in one season, it is highly likely that Season 3 will set up the battle between Saitama and Garou. If the adaptation stays faithful to the manga, we could see an epic battle between the two towards the end of the season or leading into a possible One Punch Man Season 4.
