I'm not entirely sure specifically what a 'beerus raps beerus fanfic' is about without more context. It could potentially be a fan - created story where the character Beerus is rapping. Maybe it involves Beerus expressing his thoughts, his powers, or his experiences in the form of rap within the context of a fan - made fictional narrative.
Power is a common theme. As the dark prince, Vegeta often struggles with the pursuit and control of power. Another theme is redemption. Many fanfictions explore whether he can overcome his dark side.
You could try looking on fan - fiction websites like Archive of Our Own or FanFiction.net. They usually have a wide variety of fan - created works, and there's a good chance you might find a 'beerus raps beerus fanfic' there.
Beerus would likely be more powerful. He is a god of destruction in his own universe with incredible cosmic powers. Naruto is extremely powerful in his world, but his power is mostly based on chakra and ninjutsu, which is on a much smaller scale compared to Beerus' ability to destroy planets with a flick of his finger.
The main characters are obviously Prince Vegeta and Bulma. Vegeta is the Saiyan prince, known for his pride and combat skills. Bulma is the brilliant scientist on Earth. In this fanfiction, their relationship is often the central focus, with all their differences and similarities playing important roles.
One popular 'Prince Vegeta loves Bulma' fanfiction might be 'Vegeta's New World' where it explores their relationship in a different Dragon Ball universe setting. It shows how Vegeta's love for Bulma changes his character in unique ways.
In such a fanfiction, one possibility is that Vegeta and Bulma could have an adventure together. Maybe they explore a new planet and face some unknown threats. Vegeta's combat skills combined with Bulma's intelligence would make them a great team.
Well, Naruto could be in awe of Beerus' power. Maybe he tries to learn some of Beerus' combat techniques. Since Naruto is known for his determination, he might pester Beerus to train him.
With King Kai, Beerus as a girl could have a different kind of relationship. She might be more patient with him. King Kai might be a bit more nervous around her at first, but then they could develop a more comical and friendly rapport, with Beerus teasing him in a more light - hearted way.
One interesting plotline could be Vegeta trying to understand human emotions while being in a relationship with Bulma. For example, he might struggle with expressing his love in a way that Bulma can understand. Another could be them facing challenges together, like threats from other villains that target their relationship or family. And there could also be a plotline where Vegeta has to adapt to Earth's culture more deeply because of his relationship with Bulma, which includes things like participating in Earth's holidays or social events.
