Well, it could be about Naruto somehow getting involved in the world of God of War 4. Maybe he teams up with Kratos. They could fight against some common enemies like powerful demons or dark forces that threaten both Naruto's world and the world of God of War. Naruto's jutsu combined with Kratos' brute strength would make for some epic battles.
At first, Kratos might see Naruto as a weakling because he doesn't look as physically imposing as the warriors in his world. But when Naruto shows his combat skills and his ability to quickly adapt in battle, Kratos would start to see him as an equal. Naruto would be in awe of Kratos' strength and might try to learn from him. They would have a relationship that grows from mutual suspicion to mutual respect. For example, Naruto could offer his help when Kratos is facing a horde of enemies, and Kratos would in turn protect Naruto when he is in a vulnerable situation.
One possible plot could be that Naruto is somehow transported to the world of God of War. He teams up with Kratos. Naruto's jutsu and his never - give - up attitude might impress Kratos. Together, they could face a common enemy, like a new powerful demon that threatens both their worlds. Naruto's ability to sense chakra could help them track the demon, while Kratos' brute strength and combat skills would be useful in direct battles.
Another possibility is that there is a new threat that emerges from the combination of the two universes. Some sort of evil entity that has the powers of both the Naruto universe, like the ability to use chakra, and the dark magic from the God of War world. Naruto and Kratos would have to learn to trust each other quickly in order to stand a chance against this new foe. They might start off at odds with each other due to their different backgrounds and fighting styles, but eventually realize that they need to work together.
Naruto and Atreus could be the main characters. Naruto, with his exuberant and positive personality, could contrast well with Atreus' more somber and in - process - of - growing - up nature. They could learn from each other and face challenges together, like dealing with the various mythical creatures in the God of War 4 world.
They could have some interesting exchanges. Naruto might try to cheer Kratos up or get him to open up more. For instance, Naruto could share his story of growing up an orphan and how he found purpose in protecting his village. Kratos might respond with his own tales of loss and vengeance, but in a more gruff way. And in combat, Naruto could use his speed and agility to distract enemies while Kratos goes in for the heavy blows.
In fanfiction, anything is possible, and Percy being the God of War is one such creative concept. Fanfic writers like to blend different elements from various sources. If Percy is made the God of War, it could change the entire power structure within the fictional universe. He might have to deal with new enemies, form different alliances, and face challenges that are typical for a God of War. His relationships with other characters would also be greatly affected, as his new status would bring a different level of respect or fear from those around him.
In some fanfictions, Naruto could potentially be depicted as a 'war machine'. Fanfiction often takes creative liberties with characters. Some authors might explore a darker or more militaristic side of Naruto, where his powers are used in a very aggressive, war - like manner. However, this is a departure from his more typical characterizations in the original series.
There's also 'Thor in the Mortal Realm' which takes Thor out of his usual Asgardian setting and into the world of mortals. This fanfiction is interesting as it makes Thor face new challenges and interact with different beings, and the author does a good job of describing the new environments and how Thor adapts to them. It really gives a fresh perspective on the character.
One possible fanfiction could be about the Princess having a secret alliance with Poseidon. Maybe she was promised power in exchange for helping him against Kratos. However, as the story unfolds, she realizes the true nature of Poseidon's brutality and has a change of heart, ultimately choosing to side with the forces of good instead.
