With the massive success of the phenomenal anime series "One Punch Man," it is only fitting for the series to get a green light for a second season. And it seems like fans can now heave a sigh of relief as the producers recently confirmed that season 2 is on the way and is expected to release in 2017.

The highly anticipated confirmation has been announced through the anime's official Twitter account. In the said post, the return of the bald-headed hero has been implied with an image of what looks like Saitama's fist, with a big number two in front - a clear confirmation of "One Punch Man" Season 2.

However, much to fans' dismay, no exact date was mentioned in the said post. This led to speculations that the second installment is most likely to arrive sometime next year. There are also rumors claiming that "One Punch Man" Season 2 might feature 19 episodes compared to last season's 12-episode run.

Meanwhile, as "One Punch Man" Season 2 release becomes more concrete, fans have been theorizing non-stop as to what will be the plot of the show's second installment. Rumors have been circulating online that season 2 will showcase Saitama's strongest opponent.

Rumors suggest that Garou is going to be Saitama's toughest enemy in "One Punch Man" Season 2. Apparently, Garou is the only character who can take on and survive Saitama's powerful punches. He can also put up a great fight which will intrigue the bald-headed hero.

On the other hand, others claim that Saitama's most trusted sidekick, Genos, is going to be his ultimate enemy. According to reports, the two might have some sort of misunderstanding that will cause the rift in their friendship, eventually pushing Genos to seek Saitama's defeat.

Aside from Garou and Genos, other names speculated to be Saitama's enemy in "One Punch Man" Season 2 will Lord Boros and Amai Mask. However, no confirmation has been made regarding this matter, so fans should take everything as mere speculations for now.
