Well, many Zeno Bell fanfictions have a theme related to the world they exist in. For example, they might explore the magic or the culture of their fictional world more deeply. There could also be a theme of redemption, where one of the characters has made a mistake in the past and the other helps them to make amends. Additionally, the theme of family - like bonds can be seen, where they feel like family to each other even if not related by blood.
Another good one is 'Journey with Zeno'. This fanfiction takes the reader and Zeno on an adventure together. It's exciting as it has a lot of action sequences while also exploring the growing relationship between them. The author does a great job of making the reader feel like they are part of the story.
I haven't actually read this fanfic yet. But if it's about Zeno and the Grand Priest, it could be really interesting. Maybe it explores their relationship in a whole new way, like how they interact behind the scenes in the multiverse. It could also introduce some unique plot twists based on their powerful positions in the Dragon Ball universe.
Friendship is a common theme. Given their different personalities and abilities, how they become friends and support each other. Another is adventure, as they might team up to face various threats in their fictional world.
One common theme is adventure. Since the original story likely has elements of adventure, fanfics in this pairing often continue that trend. Another theme could be love and romance, exploring the relationship between Yona and Zeno in different ways, like how they first fall in love or how they overcome obstacles in their relationship.
One common theme is adventure. Since both Lucy and Zeno can be characters in action - packed stories, their fanfiction often involves them going on quests together.
Perhaps Gohan meets Zeno during a multiverse tournament. Gohan, being the smart and powerful warrior he is, could start a conversation with Zeno about the importance of protecting all universes, not just for the sake of power but for the life forms in them. Zeno might be intrigued and start to see the universes in a new light.
In a fanfiction, Zeno and Shin - ah could have a spiritual journey. Since Zeno has his unique immortality and Shin - ah has his dragon powers, they might enter a dream - like realm where they meet the spirits of the past dragons. There, they learn about the true origin of their powers and the history of the dragons that has been long forgotten. This knowledge could then be used to help Yona in her quest to reclaim her kingdom.
A fanfiction could be set in a parallel universe where Zeno and Shin - ah are the main characters instead of Yona. They could be on a mission to find a cure for Shin - ah's dragon powers that are slowly consuming him. Zeno, with his immortality, would stop at nothing to save his friend.
