Another possibility is that some of the more power - hungry ninja from Naruto's own world might become antagonists. They could be jealous of Naruto's new connection with Ryu Hayabusa and the potential power and knowledge he could gain from it. These ninja might try to undermine Naruto or even try to harm Ryu to prevent Naruto from getting stronger. Maybe some of the rogue ninja or the hidden enemies within the ninja villages would see this as an opportunity to make a move against Naruto.
In this kind of fanfiction, Naruto might learn new fighting techniques from Ryu Hayabusa. Ryu is known for his ninja skills in his own universe, so he could train Naruto in a different way compared to what Naruto is used to in the original Naruto world.
Perhaps the main antagonists would be the dark forces in the universe that are threatened by the growing power of the Loki - Naruto duo. These could be powerful sorcerers or ancient evils. Or, it could be Loki's own family members who oppose his newfound relationship with Naruto, seeing it as a distraction from his duties in Asgard.
Naruto might become more serious about combat. Ryu Hayabusa is known for his intense focus in battle, and Naruto could adopt this trait. Instead of his sometimes impulsive fighting style, he would be more calculated, thinking several steps ahead like Ryu.
Perhaps the fanfiction could revolve around Naruto time - traveling to the world where Ryu Hayabusa exists. There, he witnesses Ryu's battles and is in awe of his strength and honor. Naruto then decides to train under Ryu to become stronger. During this training, Naruto has to adapt to a different style of combat without his usual ninja tools. He learns to rely more on his body and speed, like Ryu. This experience changes Naruto's perspective on fighting and when he returns to his own world, he brings back a new sense of confidence and fighting ability.
The shinobi council could be antagonists. They would be very suspicious of Naruto being adopted by Jenova, fearing that he will bring destruction to the village. They might try to isolate or even eliminate Naruto.

One possible main antagonist could be Frieza. Imagine if Frieza somehow found his way into the Naruto universe. He would be attracted to the chaos and power struggles there. Goku and Naruto would have to team up to stop him from taking over the Naruto world. Frieza's cold - blooded nature and his desire for power would put him at odds with our heroes. His powerful abilities would be a huge threat to both Naruto and Goku, especially since Naruto is still learning about the new powers Goku is teaching him.
It could be a group of powerful warlords or samurai who oppose Naruto's new - fangled ideas. They might see his ninja - like abilities as a threat to the traditional order of the Taisho period.
