The release date for "One Punch Man" season 2 remains uncertain but there are speculations that the animated series will return before 2016 ends.

Fans have long waited for an announcement of the series' second season premiere date but there have been several delays, according to reports. One of the reasons behind the delay is the current run of the English version. Season 1's English version is currently on Toonami and rumor has it that once this comes to an end, season 2's release date will be announced.

Season 1 is expected to end around October or November, which is just close by. With that said, the announcement for season 2 could be given as early as September and the premiere is expected to happen shortly after season 1 ends.

As for the plot, protagonist Saitama is said to face a real challenge in the upcoming season. He will reportedly encounter some tough rivals in season 2, which should put his punching abilities to the test.

There are also speculations that Saitama will become vulnerable to his enemies after losing the ability to deliver powerful punches. It was even said that the second season will focus on his battle with Amai, with Saitama on the losing end.

Should Saitama face this fate, his protégé Genos might take his place until he fully recovers, GamenGuide reported. Genos is now rumored to be the center of season 2's plot.

Previous rumors also suggest that "One Punch Man" season 2 will have a love story to tell about Saitama. What's even more interesting is that there will be a love triangle brewing, rumors claim.

Although rumors about the series returning before 2016 ends should excite all fans of "One Punch Man," it should be noted that these are not confirmed by the series' creators. Readers are still advised to take reports with a pinch of salt until an official confirmation is given.
