Well, a plot could involve Beerus accidentally getting trapped in the Naruto world. Naruto, sensing his immense power, initially thinks he's an enemy. But as they interact, Beerus discovers the concept of ninjutsu and Naruto learns about Beerus' god - like abilities. They could team up to fight a common enemy, like a powerful new Akatsuki member who has a jutsu that can disrupt the balance of the universe, which Beerus can't allow.
Perhaps in the fanfiction, Beerus hears about the Sage of Six Paths in the Naruto universe and is interested in meeting someone with such power. He travels there and meets Naruto, who is seen as a successor to the Sage's power. Beerus decides to train Naruto in his own way, pushing Naruto to new limits. In return, Naruto shows Beerus the bonds of friendship and loyalty in his world, which Beerus starts to admire.
In this fanfiction, perhaps Naruto's training takes a new turn. Since he is the son of Beerus, he might have access to different types of training methods. His friends in Konoha could be both amazed and a bit worried about his new powers. Naruto could also use his Beerus - related powers to protect Konoha from threats that are beyond the normal scope of the Naruto world, like an invasion from a powerful interdimensional foe. And there could be a lot of drama as Naruto tries to balance his normal ninja life with his new - found divine heritage.
Well, one possible plot could be that Naruto is somehow brought to the Dragon Ball universe and is raised by Beerus. Beerus, being a powerful god, could train Naruto in ways that combine the techniques of the Naruto world with the power levels of the Dragon Ball world. Maybe Naruto would learn to use chakra in new ways influenced by ki. And together, they might face threats that are common to both universes, like some powerful villains who want to take over both the Naruto world and the Dragon Ball world.
Well, it could be a story where Female Beerus takes Goku on a journey through different universes to find a special kind of food that only exists in a very remote place. Along the way, Goku trains in new ways under Beerus' watchful eye. They encounter various challenges and obstacles that test their skills and their relationship.
In a 'Gine meets Beerus' fanfiction, perhaps Gine is on a mission to seek help for the Saiyan race. She hears of Beerus' power and decides to approach him. When they meet, Beerus is amused by her courage. Gine tells him about the tyranny of Frieza over the Saiyans. Beerus, who has his own sense of justice, decides to keep an eye on Frieza. He also gives Gine some advice on how to better protect the remaining Saiyans, like teaching her some basic techniques to hide their ki more effectively.
A different take on a Naruto - Beerus fanfiction could be a story where Beerus decides to train Naruto. Beerus is an extremely powerful being, and his training methods would be very different from what Naruto is used to in the Hidden Leaf. This training could unlock new levels of power for Naruto, and also lead to some humorous moments as Naruto tries to adapt to Beerus' strange ways.
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.
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 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 possible plot could be that Chronoa, the Supreme Kai of Time, discovers a threat to the timeline that only Beerus can help with. They embark on a journey through different eras in the Dragon Ball Z universe, facing various challenges and foes together. Along the way, they develop a deeper understanding of each other's powers and personalities.
One interesting plot twist could be that Goku and Beerus end up teaming up instead of fighting. Maybe they discover a common enemy that is even more powerful than them. Another could be that Beerus loses his power temporarily and Goku has to protect him from other villains while also trying to figure out how to return Beerus' power.
