One Punch Man

Saitama is out shopping with Genos in tow when the pair come across G4, a demonic robot dispatched by “The Organization” on a mission to eliminate King. They decide to watch King battle the mighty robot in order to observe his abilities firsthand.

With the annihilation of three Class A heroes and countless criminals with bounties on their heads, Garou issues a declaration of war on the Hero Association and leaves Sitch quaking in fear of his ruthless fighting prowess.

Garou continues his hero hunting and becomes the target of a manhunt himself for his ruthless behavior. The Class S, rank 3 hero Silverfang, who once expelled Garou from his “Fist of Flowing Water Crushing Rock” dojo, begins searching for his former pupil with his brother Bomb. Meanwhile, Garou begins a battle with the S Class hero Tank-top Master and his disciples.

An executive at the Hero Association called Zeimeet has been attacked by Garou. After issuing a cautionary memo, the Association sends the Class S hero Metal Bat to bodyguard for a Director named Narinki and his son Waganma. When the VIP’s are suddenly attacked by Centikohai and Venus Peopletrap, Metal Bat quickly dispatches both monsters.

Cruel monsters of Threat Level Tiger and above have begun a simultaneous attack on every human city. While the heroes are busy holding off the attackers, other members of the Monster Association attempt to kidnap Hero Association VIP’s. Later, Phoenix Man approaches Garou with an invitation to join the Monster Association after watching the “human monster” battle Metal Bat.

The Super Fight tournament kicks off with Class A hero Lightning Max being defeated by Suiryu via a single kick in the opening match. Genos is in the crowd to observe Saitama fight, but he rushes out to take on multiple monsters who have appeared in City C, while elsewhere countless monsters are wreaking havoc in multiple areas.

The Super Fight tournament is headed for its grand finale with both Saitama and Suiryu gaining one of the final four spots. Terrible Tornado, Child Emperor, Drive Knight and other Class S heroes, called to action by the rising tide of monsters, begin engaging the enemy in various locales.

After Saitama is exposed and disqualified for impersonating, Suiryu wins the Super Fight tournament by default. As he’s about to be feted, though, the now monsterfied champion of the first Super Fight, Goketsu, appears with the aim of forcing the tournament competitors to all become monsters. As they begin to do so, Suiryu takes them all on alone.

Goketsu, one of the strongest creatures in the Monster Association, and the monsterfied Bakuzan toy with Suiryu. Realizing that no one is coming to save him, Suiryu finds himself in the depths of despair when Saitama suddenly appears. Before long, the attack by the Monster Association quietly ends, just as Gyoro-Gyoro had planned it.

The “Monster Association” claims responsibility for their members’ destructive actions with a message to the heroes that doubles as a challenge, giving them three days to rescue the hostage Waganma. The Hero Association begins preparations for its showdown with the monsters, but Metal Knight refuses their request for support.

The eight heroes have chased Garou down and surrounded him at last. However, using his extraordinary ability to quickly read an opponent’s fighting style, Garou begins to counterattack. Then, as the tide of battle turns and all eight of the heroes are taken out, Genos rushes into the fray powered up by an array of new parts.

Genos is in the midst of battling Garou when Silverfang and Bomb, who had been on the hero hunter’s trail, join the fray. Bomb uses his Fist of Whirling Wind Slashing Steel to dispatch countless monsters. Garou, already seemingly at death’s door, tries to fend off the attacks of his former master in a merciless showdown of the Fist of Flowing Water Crushing Rock.
