It expands the universe by exploring the backstories of the characters more deeply. For example, we might learn more about the childhood of characters like King. It also creates new scenarios for the heroes to face, like battles in different dimensions. This gives more depth to the world of One Punch Man.
Punch Man: The Strongest Man was an RPG mobile game produced and distributed by Beijing Tianma Space-Time Network Technology Co., Ltd., adapted from Punch Man anime. The game was officially open for testing on August 16, 2019. Players can constantly improve their character's combat strength, fight against all kinds of monsters with many heroes, and protect the world. The game supported multiplayer and light RPG gameplay, recreating the animated plot, explosive battles, and popular characters. Players could collect super popular characters and experience the original special effects and intense combat. The game provided a variety of combat mechanisms and gameplay. Players could train with Saitama and win generous rewards. The game can be played on Android, iPhone, and PC.
One interesting concept could be exploring the backstories of the side characters in more depth. In fanfiction, authors often expand on the lives and motives of characters like Genos or King that we don't get as much of in the original manga or anime. For example, they might write about Genos' training before he met Saitama, or how King actually became so feared in the hero community despite his lack of real combat ability.
Well, in some fanfictions, there are storylines where the monsters form an alliance to take on Saitama. This forces the other heroes to work together in new and different ways. There are also stories that focus on the backstories of the lesser - known heroes. For example, a fanfiction could explore how Mumen Rider got his start as a hero and his journey to becoming the symbol of perseverance that he is. Some fanfictions also like to play with the idea of Saitama losing his powers temporarily and how he copes with it.
Genos is also a favorite. Fanfiction authors might develop his relationship with Saitama further. For example, they could write about how Genos becomes even more determined to be like Saitama, or how he protects Saitama from threats that Saitama might not even consider serious. His backstory as a cyborg and his quest for revenge are also rich areas for exploration.
The concept could be expanded by giving the punch different properties. For instance, it could have the ability to nullify an enemy's special powers instead of just knocking them out physically.
In some fanfictions, the strongest punch could have a different impact on Saitama himself. Instead of being a simple display of his overpowered strength, it could start to drain his energy in a new way. This would add an interesting twist to his character, as he would have to be more cautious about when and how he uses his ultimate move.
The story mainly follows Saitama, a hero who can defeat any opponent with just one punch. It shows his daily life as a hero, his interactions with other heroes, and the various threats that he and his comrades face in a world full of strange and powerful monsters.
Saitama is the most prominent character in 'One Punch Man Hero Story'. He's the one with the amazing strength of defeating enemies with just one punch. Genos, a cyborg, is another main character. He admires Saitama and becomes his disciple. There are also other characters like King, who has a reputation of being a very powerful hero but in reality, he just has a knack for being in the right place at the right time. And there are heroes from the hero association like Tatsumaki, a very powerful esper.
One interesting storyline could be about a new hero rising through the ranks of the Hero Association in an unexpected way. Maybe a hero with no super strength but extremely high intelligence devises unique strategies to defeat monsters, which challenges the traditional view of what a hero should be in the One Punch Man universe.
