Saitama might have to overcome some stumbling blocks to gain victory in "One Punch Man" season 2.

Spoilers for the upcoming sequel suggest that a nasty opponent from the past will return this season in his quest to beat Saitama. Lord Boros, who was knocked down by Saitama in season 1, will make a comeback in the next season to bring back his honor and pride. Although he already had a taste of Saitama's power punches in the previous season, spoilers say that he is more than eager to face and fight him again.

Fans find it surprising that Lord Boros would still want to face Saitama in the fighting field once again despite his adverse fate in their initial battle. According to reports, he is confident to face Saitama this time because of a new power that he has acquired, which could place the odds against Saitama. This power allows him to regenerate and will make it hard for Saitama to prevail over him.

Although Lord Boros is one of the most talked-about opponents of Saitama in the upcoming season, Garou is another threat that may decapitate Saitama. Garou and Lord Boros are just two of the many foes that Saitama needs to conquer in season 2.

Meanwhile, a previous report revealed that the real battle will begin only in season 2. The upcoming season has been in the works since February, and despite rumors of delay, fans still hope that it will premiere sometime in the middle of this year.
