Often, the fanfiction will have Naruto using his ultra instinct to face off against enemies that were previously too powerful for him. This could be new, made - up villains or existing ones from the Naruto series like Kaguya. The battles are intense as Naruto has to adapt his fighting style to fully utilize the ultra instinct, and these battles usually drive the plot forward and keep the readers hooked.
Another interesting plot point is how other characters react to Naruto having the ultra instinct. Some are in awe, some are jealous, and others try to learn from him. In one fanfiction, Sasuke is initially skeptical but then realizes the potential of this new power and tries to work with Naruto to understand it better. This creates a whole new dynamic in their relationship.
A common plot point is Naruto's initial struggle to control the ultra instinct. It's not easy for him to harness this new power, and we see him face setbacks and challenges in the fanfiction. For example, he might accidentally use it at the wrong time or struggle to maintain it during a fight.
One idea could be Naruto discovers a hidden ancient jutsu that unlocks his ultra instinct - like powers. He then uses these powers to quickly defeat enemies in the Fourth Great Ninja War, surprising everyone including Sasuke. Another could be Naruto training in a secret dimension where he gradually attains ultra instinct and has to face off against a new, powerful and unknown enemy that threatens the entire ninja world.
Another challenge is adapting his fighting style. Naruto's existing fighting style is based on his ninja training and the use of chakra. Ultra Instinct is a completely different concept. He has to figure out how to integrate the new power into his attacks and movements without losing his own identity as a ninja. For instance, he can't just abandon his signature Rasengan, but needs to find a way to use it in conjunction with Ultra Instinct abilities.
There are indeed Naruto fanfictions where he has Ultra Instinct. Fanfiction writers like to experiment with different power combinations. By giving Naruto Ultra Instinct, they can create really exciting battle scenes. For example, Naruto could use Ultra Instinct to dodge attacks more effectively during a fight with a powerful enemy like Madara, adding a whole new dimension to the story.
Often, it begins when Naruto has a moment of deep self - reflection. He realizes the limitations of his current power and starts to explore new ways to fight. In the context of the fanfiction, this exploration could lead him to the path of learning Ultra Instinct. For example, he might encounter a wise character who gives him some cryptic advice that sets him on this journey.
One idea could be exploring how Goku further masters Ultra Instinct in ways that are different from the canon. For example, he might have to face an enemy that can nullify his normal Ultra Instinct attacks, so he has to find new ways to use it, like combining it with Kaioken.
One possible plot development could be Goku struggling to control the Ultra Instinct state for an extended period. This might lead to him accidentally causing damage to his surroundings or even to his friends while in this super - powered state. Another could be that enemies take advantage of his 'stuck' situation, seeing it as a vulnerability to attack him when he can't fully regulate his power.
A plot could involve a mysterious figure from another dimension arriving in the RWBY universe with Ultra Instinct abilities. This figure could either be an ally or an enemy. If an ally, they could teach the RWBY characters how to access this power. If an enemy, the RWBY team would have to figure out how to counter this seemingly invincible ability. Also, perhaps there could be a side - story where a non - combatant character in RWBY, like a mechanic or a strategist, plays a crucial role in helping a fighter understand and use Ultra Instinct.
Yes, it can be a great concept. Combining Naruto's ninja skills with the Ultra Instinct concept from Dragon Ball can lead to some really exciting and unique storylines. Naruto already has his own chakra - based powers, and adding Ultra Instinct - like abilities would take his power level to a whole new dimension. It could also create interesting interactions with his friends and foes as they react to this new power.
One thing that could happen is that Naruto would become much faster in combat. Ultra Instinct gives the user incredible speed and reflexes. So Naruto could dodge attacks that were previously impossible for him to avoid. For example, he might be able to effortlessly avoid Sasuke's Chidori in a new and intense battle between them.
One idea could be an Ultra Instinct Goku crossing over with the Dragon Ball Super universe and the Naruto universe. He could end up in Konoha and use his Ultra Instinct to sense and counter the attacks of the ninja there. Maybe he'd even have to fight some of the powerful ninjas like Naruto or Sasuke in a friendly sparring match to test their skills against his new form.
