In some fanfictions, the fight might start with Beerus toying with Goku. Goku, being the tenacious fighter he is, gradually adapts and starts to pose a real threat to Beerus. There could also be a scenario where Goku discovers a new power during the fight that levels the playing field against Beerus. For example, he might tap into some hidden Saiyan potential that even Beerus didn't expect.
There are fanfictions where the fight is a long - drawn - out battle. Goku uses his various techniques like the Kamehameha and Spirit Bomb in his SSJ4 form. Beerus, in response, uses his godly ki blasts and his superior combat experience. Sometimes, the fight might involve other characters interfering. For instance, Vegeta could join the fight to help Goku, or Whis might step in to stop the fight before it gets too out of hand.
One scenario could be that Goku surprises Beerus with his speed and initial attacks as SSJ4. But then Beerus counters with his hakai and forces Goku to dodge constantly. Another could be that Beerus underestimates Goku at first and Goku manages to land some powerful blows.
Well, in many fanfictions, SSJ4 Goku is often depicted as having a chance against Beerus. SSJ4 Goku has shown incredible strength and combat skills. But Beerus has the power of a God of Destruction. His hakai ability could potentially wipe Goku out. Still, if the fanfiction is written in a way that gives Goku some new power - up or a special advantage, he could win. It really depends on the creative direction of the fanfic writer.
In fanfiction, it's really hard to say for sure. Different fanfictions might have different outcomes. Some might make Goku Black super powerful and give him the win, while others would keep Beerus as the dominant force due to his status as a God of Destruction.
In some fanfictions, the fight might start due to a misunderstanding. For example, they might both be sent on a mission to retrieve the same item. Percy thinks Jason is trying to steal it from him and vice versa. If the fight is in an underground cave, Percy could use the underground water sources to his advantage. He could create water tentacles to grab Jason. Jason could use the air pockets in the cave to create small explosions or gusts of wind to break free. In a different scenario, like in a desert, Percy would have a harder time as there's not much water. But he could still create water from the moisture in the air. Jason would have an easier time controlling the wind in the open desert area.
Goku being born with SSJ4 in fanfic would likely make him a force to be reckoned with from infancy. This could result in quicker power-ups, different battles, and maybe even a shift in the balance of power among the characters.
One scenario could be that Goku enters a special realm where time and space work differently. In this realm, the laws of biology are altered, and his tail simply regrows. Another might be that an enemy's attack, instead of harming him further, accidentally triggers a hidden regenerative ability in Goku that causes the tail to grow back.
One possible plot could be Goku from the SSJ4 form crossing over into the world of Dragon Ball GT. He could encounter new threats that require his ultimate form to defeat. Maybe he teams up with the other Z - fighters in that universe to face off against a powerful and ancient evil that was sealed away long ago and has now been unleashed.
The plot might involve Goku SSJ4 teaming up with some unexpected allies in the Tournament of Power. He could be using his SSJ4 powers in creative ways, like combining them with the techniques of his new allies to gain an edge over the other universes' competitors.
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 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 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.
