"One Punch Man" has been rumored to return for a Season 2 in 2017. While fans are already excited for the show's epic comeback, the plot seems to remain a mystery. However, this is not the case anymore, as we now have an idea of the story arc of "One Punch Man" Season 2.
It has been revealed that Saitama will finally be facing much stronger enemies in "One Punch Man" Season 2. These enemies could take more than one punch from the bald hero. There have been rumors saying that Lord Boros will be making a comeback and once again face Saitama in the next season of "One Punch Man."
Similarly, Garou will also be challenging Saitama in "One Punch Man" Season 2. This would be an interesting match-up, as the two are both non-powered characters. It has been confirmed back in September that the production of "One Punch Man" Season 2 is in the works. However, there have been no details revealed since then, especially when it comes to the plot.
In the original manga where "One Punch Man" Season 2 is based on, Saitama, along with the Hero Association, is going to deal with Garou, who is also known as the Human Monster. Being a non-powered character, Garou's strength comes from hard work and training to earn his abilities.
Garou then set out to hunt all the members of the association. This now makes up the plot of "Hero Hunter" story arc. The character addition and skills revelation are also added to "Hero Hunter." The "One Punch Man" Season 2 will also reveal the origin and motivation behind Saitama's tremendous power.
"Hero Hunter" has since been remade and expanded. However, fans and experts still believe that "One Punch Man" Season 2 will be adapting the said story arc, as elements from the original version would make the story interesting and relevant to the fans. "One Punch Man" Season 2 is expected to air early next year, with updates on the official Facebook page of Anime Access.
