Well, it could be about Goku's new Ultra Instinct form affecting his relationship with Chichi. Maybe she has a hard time understanding this new side of him at first, but then they grow closer as she learns to accept it.
A possible story in this fanfiction could be that Goku, in his Ultra Instinct state, accidentally endangers Chichi during a battle on Earth. This makes him feel guilty and he tries to find a way to better control his power around her. Chichi, on the other hand, is more worried about Goku's well - being than her own safety. They then work through this situation together, strengthening their bond.
Goku, with Ultra Instinct, would be more in tune with his instincts and might be more impulsive in his actions towards Chichi. For example, he could be quicker to protect her without thinking. Chichi, in turn, would probably be both amazed and a bit scared by this new Goku.
Yes, it is possible. In fanfiction, writers have the creative freedom to reimagine the origin of characters. Goku being born with Ultra Instinct can add a whole new layer to his character development. It could mean that his power growth would be different from the original story, perhaps faster or with different challenges along the way.
You could write a fanfiction where Goku teaches others about Ultra Instinct. Maybe he tries to pass on this power to Gohan or Trunks. This would involve Goku having to understand the power more deeply himself in order to teach it, and it would also be a great way to develop the other characters.
One possible plot twist could be Goku traveling back in time to train with his past self. This would not only enhance his own power but also change the course of his past battles. For example, he could teach his past self Ultra Instinct earlier, leading to different outcomes against foes like Frieza or Cell.
One possible plot could be that there is a rift in the multiverse that brings Goku and Luffy together in a strange new world. They initially misunderstand each other and start to fight. As the fight progresses, they both realize that there is a greater threat at hand that is causing the rift. So, they team up, with Goku teaching Luffy some of his combat techniques and Luffy showing Goku the value of friendship and loyalty in a different way.
One idea could be a crossover with the Naruto universe. Goku with his Ultra Instinct could face off against Naruto in his strongest form. They might start as rivals but then realize they have a common enemy and team up. The story could explore how their different fighting styles and powers interact.
A fanfiction could focus on Goku's relationships while in Ultra Instinct. For example, how does he interact with his friends and family? Does Vegeta view him differently? In this story, Goku might struggle to control the Ultra Instinct around his loved ones because it makes him seem so detached. This could lead to some interesting emotional moments between the characters.
That really depends on personal preference. However, some popular ones often have a great balance between action and character development. For example, stories that explore how Goku's relationships change after getting Ultra Instinct can be really engaging.
Yes, he does. Goku achieves Ultra Instinct in the manga.
Goku definitely masters Ultra Instinct in the manga. This transformation gives him a huge boost in power and allows him to take on even stronger opponents.
