'One Punch Man' season 2 spoilers, news: A more expressive Saitama faces stronger enemies when series returns in October

The highly anticipated sophomore season of "One Punch Man" may not be due for some more months, but fans of the hit Japanese anime series have been speculating non-stop about what's coming next for Caped Baldy and the rest of the Hero Association.

There have been rumors of villains old and new getting caught on the wrong end of Saitama's powerful one-punch finisher. Lord Boros, who Saitama has previously defeated, seems to be on the top of the list, and fans are expecting him to return for a rematch and pose a much greater challenge to Saitama's fist than he was during their previous battle. Other potential adversaries include characters from the manga series who have not yet been seen on TV and Saitama's own apprentice, the cyborg Genos.

One character that fans are most eager to see in the anime adaptation is the Human Monster Garou, who is believed to be strong enough to give Saitama's fist an intense workout. A source speculates the two of them could meet each other on the battlefield through a Martial Arts Tournament, which is in accordance with the latest chapters of the manga series.

However, a growing list of enemies is not the only thing that awaits Saitama when "One Punch Man" returns for season 2. Latest speculations hint at a more expressive Saitama with a more rounded head compared to before. Although he will still not regain his lost hair, the show's protagonist is expected to look different with more detailed facial expressions.

The fight scenes will also reportedly undergo some improvements, like zooming in on the action, in order to give viewers of the series a more immersive experience.

The excitement for the upcoming season of "One Punch Man" will continue to heighten with more elaborate speculations until the show itself returns later this year. Rumors are pointing at a possible October premiere, but an official statement about the matter has not yet been released.
