Perhaps the story could start with Naruto not knowing about his father Loki at all. As he grows up, he experiences strange visions or powers that he can't explain. He then embarks on a quest to find out about his real father. Along the way, he meets characters from Norse mythology who either help or hinder him. He might have to face challenges that test both his ninja training and his emerging Asgardian powers, like battling a powerful demon that can only be defeated by combining a Rasengan with a magical spell from Loki's arsenal.
The plot might involve Naruto discovering his true parentage as Loki's son. This could lead to a whole new set of challenges. He may have to deal with the reactions of his friends in Konoha, who might be suspicious or afraid of his new - found heritage. Also, he could be hunted by those who want to use his connection to Loki for their own purposes.
Well, Naruto might gain some very different skills. Loki is known for his trickery and magic. Naruto could learn some illusions or more devious combat tactics. He might become more unpredictable in battle, using Loki - like deception along with his existing ninja abilities.
He'd be more mischievous. Since Loki is known for his trickery, Naruto would likely have a stronger inclination towards pranks and out - witting his opponents in a more devious way. His normal exuberance would be tinged with a bit more slyness.
He might become more devious. Instead of his straightforward, head - on approach, he could start using more underhanded tactics, like Loki. For example, he may set up elaborate traps for his enemies rather than just fighting them directly.
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.
Well, it could be really wild. Naruto's energetic and determined nature might clash or blend well with Loki's mischievousness. Maybe Loki sees something in Naruto that reminds him of himself, like being an outcast in a way. He could teach Naruto some of his magic tricks, and Naruto could show Loki the value of true friendship and loyalty.
His relationship with Sasuke might be different. Sasuke might be more wary of Naruto, seeing him as more unpredictable with Loki's powers. Naruto, on the other hand, would try to use his new powers to show Sasuke that he's still the same person at heart.
Well, Naruto could use Loki's power of illusion in really interesting ways. He might be able to create false landscapes to mislead his enemies during battles. For example, he could make it seem like there are a thousand clones when there are only a few real ones. This would give him an edge in combat as his opponents would be confused and waste their energy attacking the illusions.
The combination of powers. Naruto has his ninja abilities like the Rasengan and his chakra control, while Loki has his magic, shape - shifting, and illusion - casting. Imagining how Naruto would incorporate Loki's powers into his own fighting style would be really cool.
