One common theme is power comparison. Writers often explore how Vegito's power from Dragon Ball stacks up against the powers in the other crossover universe, like the magic in a Harry Potter crossover or the quirks in a My Hero Academia crossover.
There's 'Vegito and Naruto: The Crossover'. This fanfic combines the power of Vegito from Dragon Ball with the ninja world of Naruto. It shows how Vegito might adapt to the different fighting styles and powers in the Naruto universe. It also has some great character development for Vegito as he makes new friends and enemies.
In crossover fanfiction, Vegito Blue often brings a powerful and exciting element. His character combines the strengths of Goku and Vegeta in a unique way. For example, his combat skills and strategic thinking are enhanced due to the fusion. Writers can use him to create epic battles against various foes from different fictional universes.
In many popular crossover fanfictions, Vegito Blue is often the key to turning the tide in battles. His presence alone can shift the power balance. For example, in a crossover with the Naruto universe, his overwhelming power could be a huge threat to the ninja world.
One idea could be a Vegito crossover with the Dragon Ball GT universe. Vegito could face off against the Shadow Dragons, creating an epic battle of power. Another could be a crossover with the One Piece world, where Vegito has to navigate the Grand Line and deal with pirates. Maybe he teams up with the Straw Hats to take on a common enemy.
In vegito crossover fanfiction, characters like Jiren would be great. His strength and stoic nature would make for some intense interactions with Vegito. Also, Android 18 could be included. She has her own unique set of powers and a strong will. Her presence could add some interesting dynamics, especially if she has to team up with Vegito against a common enemy. And don't forget Frieza. His evil nature and thirst for power always make for an exciting addition to any Dragon Ball - related story.
Maybe it's because Bulma has her own established character traits and relationships in the original story. She might not fit well into the scenarios often presented in Vegito fanfic. Also, her character is more focused on other aspects like her scientific work and family in the canon, so fanfic ideas involving her in a Vegito - related context could seem out of place to her character.
One reason could be that the fanfic might distort her character. Bulma is a smart scientist, and if the Vegito fanfic makes her act in a way that's not true to her intelligent and rational self, she would seem to reject it. For instance, if the fanfic has her being overly emotional or doing things that are completely against her scientific nature just to fit into a Vegito - centered plot.
To write a Bulma leaves Vegito fanfic, start with character development. Understand Bulma's and Vegito's personalities well. Maybe Bulma has grown tired of Vegito's constant battles and wants a more peaceful life. Then, build a conflict that leads to her leaving. As you write, use vivid descriptions to bring the story to life. You can include flashbacks to show the history of their relationship. And make sure to have a resolution at the end, whether it's a reconciliation or a final goodbye.
Well, it could be that Bulma realizes that the relationship with Vegito is just too complicated or dangerous. Maybe she decides that she can't handle the chaos that often surrounds Vegito, like all the battles and threats that come with being associated with him.
