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.
Definitely. In the realm of fanfiction, Goku being born with Ultra Instinct can open up many interesting plotlines. It could potentially affect the Saiyan race's perception of him. Maybe they would see him as some sort of prodigy or even a threat. Also, his battles would be quite different. Instead of struggling to reach Ultra Instinct in a fight, he would already have it at his disposal, which could make his opponents approach battles with him in a more cautious and strategic way.
Sure. Fanfiction often takes existing concepts and twists them. If Goku was born with Ultra Instinct, it might change the entire dynamic of his relationships with other characters. For example, he might not need to train as hard in certain areas as he already has this powerful ability from the start. This could lead to different story arcs, like him having to learn how to control it better at a very young age instead of gradually unlocking it later in life.
There would be a lot of implications for Goku's character growth. In the original story, Goku's journey to achieving Ultra Instinct was a long and arduous one filled with many battles and self - discoveries. If he was born with it, he would lack that growth experience. However, he could still have other forms of growth, like learning to control his emotions better while using Ultra Instinct. His relationships with his family and friends might also be different. For instance, Chi - Chi might be more worried about his safety since he has such a powerful ability from birth, and Gohan might look up to him even more. It could also change how Goku views himself. Instead of seeing himself as a constantly evolving warrior, he might feel a greater sense of responsibility due to his inborn power.
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 storyline could be that Goku gets Ultra Instinct right when Frieza is about to kill all the Namekians. He then uses his newfound power to completely overpower Frieza and save the day. Another could be that he gets it during a battle with the Ginyu Force and easily defeats them all in one go.
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.
