Another fanfiction concept could be that the monsters in the 'Danmachi' dungeon start to mutate in a way similar to how the monsters in 'One Punch Man' are strange and powerful. This would force the adventurers in 'Danmachi' to come up with new strategies, and perhaps some of the heroes from 'One Punch Man' could come to help out, like Genos, who could provide some technological insights on dealing with these new threats.
One similarity is the presence of strong characters. In 'Danmachi', there are powerful adventurers like Bell Cranel who grow stronger over time. In 'One Punch Man', there's Saitama, who is absurdly strong. For fanfiction, this means you can create scenarios where they exchange training methods or fight side by side against a common enemy. Another similarity is the concept of a world full of challenges. 'Danmachi' has the dungeon with its various floors and monsters, while 'One Punch Man' has a constant stream of villains. Fanfiction can play on this by having characters from one series face the challenges of the other's world.
You can find 'One Punch Man' fanfictions on websites like FanFiction.net. It has a large collection of fan - created stories related to 'One Punch Man'. There are different categories and ratings, so you can easily filter and find the ones that suit your taste.
One Punch isn't a short story. It has multiple characters, plotlines, and arcs that extend over a considerable period, making it a full-fledged fictional work.
One popular aspect in One Punch Man subterranean fanfiction is the re - imagining of the subterranean races. Writers often give them more complex backstories and motives. For example, some fanfics might depict a subterranean character who has a change of heart and decides to side with the surface - dwellers. This adds an interesting layer of depth to the story as it challenges the traditional view of the subterranean as simply enemies in the original work.
There's no definitive answer as to which is better between the 'Danmachi' manga and light novel. The manga is excellent for those who are attracted to the art style and want a more immediate visual experience. The art can enhance the action scenes and character designs. On the other hand, the light novel allows for a deeper exploration of the characters' thoughts and emotions. It can also provide a more comprehensive view of the fictional world. Some people might even enjoy both, as they can complement each other. For instance, reading the light novel first can give a more detailed understanding of the story, and then the manga can offer a different visual perspective on it.
