The action continues in One Punch Man Season 2 Episode 4 as Saitama (voiced by Makoto Furukawa / Max Mittelman) will enter the Super Fight tournament disguised as Charanko.

Before that, here's a quick recap of what happened in the latest episode of One Punch Man Season 2. Episode 3, titled "The Hunt Begins," saw S-Class hero Bang / Silver Fang (voiced by Kazuhiro Yamaji / Will Barret) expelling his remaining student, Charanko, from the dojo because he did not want him to be caught in the crossfire in his hunt for Garou (voiced by Hikaru Midorikawa), also called the Human Monster and the Hero Hunter.

Due to this, Charanko confronted Garou to avenge Bang / Silver Fang and his dojo's honor. However, Garou quickly gained the upper hand in the fight using the secret martial arts technique that his former master taught him.

While Charanko survived the attack, he was next seen in the hospital, heavily bandaged and with his leg and an arm in a cast. Saitama visited him to get advice on martial arts, to which the former advised him to start with the basics and see Bang / Silver Fang.

Saitama, however, refused due to Bang / Silver Fang's old age. Charanko, then, gave him a ticket to a mixed-martial arts tournament, dubbed Super Fight tournament, so that he can observe various martial arts styles. He also cautioned him that the tournament would disqualify any impersonators.

It looks like his words go unheeded as the spoilers and predictions for One Punch Man Season 2 Episode 4 reveal that Saitama will disguise himself as Charanko to enter the Super Fight tournament. The teaser for the upcoming episode shows the fan-favorite character wearing a messy, light-colored hair wig.

Aside from Saitama, fellow heroes Lightning Max (voiced by Sōichirō Hoshi / Ben Pronsky) and "Biting Snake Fist" Sneck (voiced by Shinichiro Miki / Kirk Thornton) also join the tournament. The much-awaited event will also see the introduction of a new character, Sour Face.

Not much is known about Sour Face, other than he was once a disciple of Bang / Silver Fang, but left after Garou rampaged through the dojo. He, then, created the Sour Face Style Martial Arts and started his dojo.

One Punch Man Season 2 Episode 4, titled "Metal Bat," arrives on April 30, Tuesday.
