A really interesting fanfiction idea could be Bell Cranel having to prove himself worthy of his Zeus - related lineage. This could involve him going through a series of trials that test not only his physical strength but also his moral character, all while dealing with the regular challenges in the Danmachi world.
One unique plotline could be Bell Cranel using powers that are latent within him due to his Zeus heritage in unexpected ways. For instance, he might be able to communicate with a special type of monster that has a connection to Zeus's past.
It doesn't seem to be a widespread or commonly - used statement in the general 'DanMachi' fandom. Most of the time, the fandom is focused on either the official story, fanart, or positive aspects of fanfiction. However, in some niche discussions where fans are very critical of how the official story affects the fan - created content, such a statement could potentially come up. But overall, it's not something you'd hear every day among 'DanMachi' fans.
One great 'Bell Cranel Sword' fanfiction is 'The Ascent of Bell Cranel's Sword'. It focuses on the evolution and significance of his sword throughout his adventures. It has detailed descriptions of how the sword becomes an extension of Bell's will and power.
One great fem Bell Cranel fanfiction is 'Fem Bell's Ascent'. It explores a world where Bell is a female and how she navigates the dungeon with a different set of challenges and relationships. The story beautifully develops her character in a new light.
One interesting story could be about Bell Cranel's journey in a world where his father Zeus' powers start to manifest in him unexpectedly. He has to learn to control these newfound abilities while still maintaining his own identity and relationships in the dungeon.
It could be a character from a rival group. They see Bell Cranel as a threat to their plans and so they betray him by setting him up in a dangerous situation.
Well, one possible plot could be that Bell Cranel starts to discover hidden powers within himself that are related to Zeus's family legacy. Maybe he has to face challenges from other families who are envious or afraid of this newfound connection. He might also meet characters who knew Zeus and they could guide him on how to use these inherited powers in a proper way.
Bell's character may develop through the challenges he faces in the Zeus Familia. For instance, if he has to compete with more experienced members, he'll become more determined. He might also become more confident as he accomplishes difficult tasks. His sense of loyalty to the familia would grow stronger over time.
It concludes with Bell Cranel achieving a significant level of growth both as an adventurer and as a person. He overcomes many of his initial insecurities and becomes a more confident and capable hero in the world of Orario.
In such a fanfic, perhaps a significant plot point is Bell's role in resurrecting the Zeus Familia's former glory. The familia may have faced some setbacks before Bell joined. He could be the key to bringing back their lost prestige. This might involve him going on a series of epic adventures to retrieve lost artifacts or knowledge. Along the way, he would meet various characters, some of whom might try to stop him, while others might become his allies. His journey would not only be about physical strength but also about his character development as he matures within the Zeus Familia.
