The world is a dangerous place with monsters, assasins, criminals and evil organizations popping up everyother day of the week. But there are always those distractions to help with the stress of daily live, things like anime or videogames. But one otaku with a lot of time on his hands needs cash for food and merch, so he becomes a moster hunter alongside his neighbour who is a hero for fun. One Punch Man is owned by ONE and adapted by Yusuke Murata. I don't own any of the pictures used.

In this story we see our bald hero Saitama become a symbol of strength and peace as he takes on the strongest enemies the earth has seen. This all started when he was walking back home and out of nowhere he sees a young girl with green hair fly towards one of the buildings, as she's about to get killed by the monster Saitama sends a normal punch and instantly kills it. As she falls accepting the fact that she's going to die Saitama saves her and carries her to his house to help her out. Find out what happens... (Some spoilers from the webcomic)

The era of heroes is over, with the hero association almost extinct and the espers now living in secrecy, the talented son of a legendary esper couple starts attending a school which is under the control of the devils. Raised with the mentality that all demons and evil spirits are enemies and carrying an enormous power that is still unknow to most devils, how will he fit in this new life?

A terrifying God-class monster destroyed Earth in one punch and is now fighting Saitama! "You're strong, but can you defeat me?" Magneton smirked. Read about Saitama's epic journey as he travels through the galaxy and enters a timeline where he has retired from being a hero. Along the way, you'll find plenty of epic action, breathtaking adventures, an engaging storyline, and Saitama's normal, humorous, and laid-back personality!

The S-Class and a few others watch One Punch Man. This on Fanfiction.net too.

A hero from different universe unknowingly arrives in the One Punch Man universe. He holds a dark past with him but wants to try to start over from scratch. (Summary changes) (Spelling errors) I've also decided to combine two my sequel books to this just to make the first book expand.

When meeting a worker, Miyu, at the udon shop him and his master once went to, he finds himself befriending and learning from her as well. The two of them create an unexpected friendship and help each other out on achieving their goals.
