One Punch Man

Saitama becomes a hero as a hobby. However, he has become so strong that he can defeat his opponents with just one punch.

A monster is moving toward City Z--one that has been created by the mysterious organization known as The House of Evolution.

Saitama and Genos glean information about the House of Evolution and its founder, Dr. Genus.

A terrorist group has appeared in F City and leading them is a large person wearing a battle suit named Hammerhead.

Saitama decides to become a professional hero and takes up the test together with Genos. He barely passes while Genos achieves full marks.

To remain on the "Hero" list Saitama has to show some activity in every week. Currently the City Z is defined as the 'ghost town'. Heroes are gathered together to find out whats going on.

A large meteor from space is heading towards the City Z and the Hero Association tries to get the S-ranked heroes to help.

A bunch of creatures from the sea invades City J. Many heroes arrive to stop them. However, they are all defeated by the Deep Sea King.

Genos confronts the Deep Sea King in order to protect the people in the shelter. However, while trying to protect a child, he is injured.

The S-ranked heroes are suddenly called to gather. Saitama and Genos are visiting Silverfang's dojo and they follow him to the gathering.

Saitama has entered the spaceship that is above City A alone. He goes around destroying the inner structure of the spaceship.

Inside the ship, Saitama continues his confrontation with Lord Boros. Will Saitama finally be able to fight with all his strength?
