In this kind of fanfiction, the power hierarchy in the Dragon Ball universe would be completely shaken. Goku's victory over Beerus could inspire other characters to strive for greater power. New alliances might form, and old ones might break. The Z - fighters could see Goku in a new light, either as a hero or a potential threat. The story could also explore Goku's moral compass. Killing Beerus, a god, might make Goku question the limits of his power and the responsibility that comes with it. There could be a lot of internal and external conflicts that make for an exciting fanfiction.
Well, in the original Dragon Ball series, Beerus is an extremely powerful god of destruction. For Goku to kill him in a fanfiction would be a huge shock. However, in the realm of fanfiction, anything can happen. Fanfic writers often like to explore 'what - if' scenarios that deviate from the official canon. It could be interesting to see how the writer would justify Goku achieving such a feat, considering Beerus' overwhelming power.
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.
Well, perhaps in this fanfiction, Goku Black makes a fatal mistake. He could underestimate Goku's ability to adapt during battle. Goku, being the experienced fighter he is, notices this weakness and uses it against Goku Black. He might use a combination of his signature moves like the Kamehameha in a new and unexpected way that catches Goku Black off - guard, leading to his defeat.
Well, in such a fanfiction, Beerus as a girl might have a different approach to her relationships. Maybe she would be more empathetic towards the other characters. For example, she could form closer friendships with Goku and Vegeta. Instead of just being feared, she might be more approachable and could even start training with them in a more collaborative way.
In this fanfiction, they might have an epic sparring session. Goku could pass on some of his old fighting techniques to Goku Jr.
There could also be a moment of self - discovery for both of them. Goku might see his past self in Kid Goku and realize how far he has come, while Kid Goku could get a glimpse of his future potential through meeting his adult self. They could share stories about their friends and enemies, like how Goku could talk about Vegeta and Frieza to Kid Goku, and Kid Goku could tell Goku about his early battles with the Red Ribbon Army.
Perhaps they would team up against a common enemy. In fanfiction, new threats are often created. They could combine their strength and unique techniques to defeat the bad guy.
Well, in many goku x beerus fanfiction, the theme of cultural exchange is quite common. Goku represents the Saiyan culture and Beerus the divine culture of the Gods of Destruction. Their exchanges can be really fascinating. Also, the theme of redemption can be found. For example, if Beerus has made some mistakes in the past, through his relationship with Goku, he might seek redemption. And of course, the theme of facing a common enemy together is prevalent. They combine their powers and strategies to take on threats that neither could face alone.
The plot might center around Goku being raised by Beerus in a more secluded place. Beerus could be training Goku to be his successor as a god of destruction. Goku would have to learn about the balance of destruction and creation, which is different from his usual Saiyan power - up goals. This would also mean that Goku would have a different view on the universe and its inhabitants. He might be more detached in some ways, but also more powerful and with a different moral code influenced by Beerus.
One common theme is power growth. Goku is always seeking to get stronger, and in fanfictions with Female Beerus, she often challenges him in new ways, pushing his limits and leading to his power growth.
