One interesting concept could be the power struggle. Beerus is an extremely powerful deity in the Dragon Ball universe with god - like powers, while Naruto has his own set of formidable ninja abilities. In fanfiction, they might explore how Naruto's chakra and jutsu would fare against Beerus' energy blasts and hakai ability. Another concept could be the clash of their worlds. The ninja world of Naruto is very different from the Dragon Ball universe, so seeing how the two settings interact, like how Naruto's friends and village would react to Beerus' presence, can be really engaging.
Beerus would probably win. He is a god of destruction in the Dragon Ball universe. His power levels are off the charts compared to Naruto. He can destroy planets with a snap of his fingers, and his combat skills are far beyond what Naruto has been shown to be capable of in the Naruto universe.
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.
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.
One aspect of Vegito and Female Gogeta fanfiction could be the exploration of their unique power combinations. In these fanfictions, writers might create scenarios where they team up against a powerful enemy. For example, they could face a new, extremely strong villain that neither could defeat alone. Their combined strength and different fighting styles would make for an exciting story.
A common theme is power escalation. Writers often make them even more powerful than in the original series, creating epic battles. For instance, they might face off against multiple foes at once, showing off their enhanced abilities.
One popular Gogeta and Vegito fanfiction might be those that explore their power levels in new and creative ways. For example, a story could have them facing an extremely powerful new enemy that forces them to combine their powers in unexpected ways.
Well, a common theme is the exploration of different universes. In gogeta crossover fanfic, the idea of Gogeta traveling to different fictional universes and dealing with their unique challenges is quite popular. It's like he could end up in a universe full of magic and have to figure out how his power works there. Another theme is the combination of fighting styles. Since Gogeta is a powerful fighter, seeing how his fighting style combines with those from other characters in a crossover is exciting for fans. And of course, there's the theme of saving the multiverse. Many fanfics have Gogeta as the key to preventing some sort of cataclysm that affects multiple universes.
