'One Punch Man' season 2 plot speculations, news: Manga artist Yusuke Murata teases new illustrations for series; Saitama to finally meet his match?

Saitama might cross paths with a new rival who's more powerful than him when "One Punch Man" returns for its second season.

Since the show has been renewed for the second installment, most of the storyline speculations centered on Saitama's future opponents. Rumor has it that Saitama will go up against a familiar enemy, Lord Boros. Season 2 will reportedly explore the "Hero Hunt" arc that centers on Saitama's match with Garou, a previous S-Class student and a powerful villain who might have an edge over him.

Another fan theory about Saitama's new enemies points to Amai Mask discovering the bald-headed hero's source of power. In season 1, Amai Mask was not in good terms with the S-Class, so it's expected that he'll be causing more trouble when the series returns. It is also believed that Saitama's skills will be put to the test when he fights against the Hero Association. While fighting with new villains, Oigel reports that Saitama will still find time to take part in a tournament. The publication claims that Saitama will sport a wig as a disguise when he joins the event.

In other news, Japanese manga artist Yusuke Murata recently showed some new illustrations he made for the series. The set of drawings show some changes in Saitama, particularly his facial expressions. Fans can recall that he usually has an inexpressive face, but Murata's new drawings hint that Saitama will have a wider range of facial reactions. As for Saitama's overall look, his signature yellow costume may also be altered. There were a few indications that the character is getting a new wardrobe this coming season, but his next outfit is still being kept under wraps.

The official release date for the second season of "One Punch Man" has not been announced yet, but recent reports claim that the show might be up for an October 2017 premiere.
