Goku in Ultra Instinct mode is extremely powerful. He has superhuman speed, strength, and can dodge attacks effortlessly. However, Luffy also has his own set of amazing abilities like his Gear Fourth form which gives him enhanced speed and power. But I think Goku would win because his combat skills and power level are just on a different scale compared to Luffy.
Well, if we consider a fanfiction crossover between Ultra Instinct Goku and Luffy. Goku has been through countless battles and has trained with some of the most powerful beings in the Dragon Ball universe. His Ultra Instinct form is the result of intense training and spiritual growth. Luffy, while incredibly strong in his own right, is more of a pirate - style fighter. His Devil Fruit powers are unique but not on the same level as Goku's ki - based powers. Goku can also sense his opponents' energy and predict their moves, which would be a huge advantage in a fight. So, more likely than not, Goku would emerge victorious in this fictional crossover battle.
Well, it's really hard to say for sure. Ultra Instinct Goku is extremely powerful with his god - like reflexes and insane combat skills. But Fairy Tail characters also have some very strong magic. If we consider Goku's speed and strength, he might have an edge. However, some Fairy Tail mages could potentially use powerful spells to counter him. So it could go either way depending on how the fanfiction is written.
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.
Well, with Ultra Instinct, Goku would be able to react extremely quickly to the DC heroes' powers. For instance, when facing Flash, who is super fast, Goku in Ultra Instinct might be able to match his speed or even anticipate his moves better. This could lead to a mutual respect between them as they test each other's limits.
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 possible plot is a crossover with the Naruto universe. Goku in Ultra Instinct mode could be mistaken for some sort of super - powered ninja. He might end up training with the Hokage or getting involved in the Akatsuki's plans. Since his Ultra Instinct gives him such incredible reflexes and power, he could easily hold his own against the strongest ninjas like Naruto in his Six Paths Sage Mode or Sasuke with his Rinnegan. It would be a clash of two very different power systems.
First, understand the characters well. Know Goku's Ultra Instinct powers, his personality, his goals. Then, when choosing a crossover universe, pick one that has elements that can contrast or complement Goku's world. For example, if it's a magic - based universe, how would Goku's physical powers interact with magic? Keep the story focused on the main characters and their development throughout the crossover.
Evangeline and Goku. Evangeline is a powerful vampire in UQ Holder. Her dark magic and immortality contrasted with Goku's pure - hearted and extremely powerful fighting style would create some interesting dynamics. They could either be at odds, with Evangeline seeing Goku as a threat to her power, or they could end up teaming up in some strange circumstances where their combined powers are needed.
If Goku with Ultra Instinct crossed into the DC Universe, his powers would be very interesting. His speed could compete with the Flash. His combat skills and power would put him in a league with Superman. But the key difference would be how his Ultra Instinct operates. In a world full of superpowers and magic, his ability to react without thinking might be seen as a very unique power. It could also interact with the Green Lantern's ring energy in unexpected ways since it's all about willpower and Goku has a very strong will.
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.
