'One Punch Man' season 2 spoilers, rumors: Who can defeat Saitama?

In season 1 of the anime series, Saitama, who was once an ordinary salaryman, became known as the strongest man in the world, having the capacity to knock out an enemy with just a single hit. More powerful enemies, however, are expected to turn up on season 2, and there are now rumors that one of them will be the one to bring down "One Punch Man."

One of the suspects of Saitama's downfall is Garou, the yellow-eyed villain whose goal it is to defeat all heroes. Their confrontation is said to take place in a tournament, where a disguised One Punch Man participates in.

Lord Boros is also suspected of appearing once again to seek revenge against Saitama, who defeated him in the first season. According to rumors, he will use a dirty trick in order to make One Punch Man lose all his powers. He will then be forced to kneel before Lord Boros. However, there is no definitive word yet that his kneeling is already the defeat that people are talking about or if it is just a temporary weakness, with Saitama rising again to defeat his enemy.

One Punch Man is also expected to go against the Monster Association, led by Psykos, who is expected to be one of the main villains of season 2. However, no details have been revealed about their bout.

Some fans are also considering the possibility that a fellow hero might lead to his defeat. Rank 1 hero Amai Mask could be someone who is powerful enough to defeat Saitama. He is rumored to have discovered a secret of Saitama, and he might use this for his benefit to overpower the bald superhero. Bofoi, or Metal Knight, an inventor who was a member-turned-traitor of the Hero Association, may also be the one to cause One Punch Man's demise. He is said to use his science know-how to develop a weapon that he will pit against Saitama.

No announcement has been made yet on when season 2 of "One Punch Man" will premiere.
