Perhaps Annabeth introduces Percy to Spider - Man. She's always into mortal knowledge and might find the idea of a superhero who swings around the city on webs fascinating. She shows Percy a movie or a comic, and Percy is just drawn to Spider - Man's underdog story, his struggle to balance his normal life and his heroic deeds, which is something Percy can relate to in his own way as a demigod.
Well, it could start with Percy stumbling upon a Spider - Man comic in the mortal world. Maybe he's on a quest that takes him to New York, and he sees the colorful pages. He's instantly intrigued by Spider - Man's acrobatic moves and sense of responsibility. He starts collecting the comics and becomes a huge fan, imagining how he could use some of Spider - Man's skills in his own battles against monsters.
Well, it could happen if Percy has an encounter with a dragon that changes his perspective. Maybe he meets a dragon that has some sort of connection to the Greek gods. For example, the dragon could be a guardian of a hidden artifact related to Poseidon. This encounter makes Percy intrigued by dragons, and he starts to study them, thus becoming a dragon fan.
Well, it could happen if Percy somehow got exposed to Batman comics or movies in the demigod world. Maybe Annabeth introduced him to it, thinking it would be a good strategic read. After all, Batman is known for his brilliant mind and strategic planning, skills that could be useful for Percy in his own battles.
Well, it could happen if Percy somehow gets exposed to the Star Wars universe. Maybe he stumbles upon a holo - projection of a Mandalorian in action while on one of his quests. The honor - bound code of the Mandalorians might appeal to Percy, who has his own strong sense of loyalty and justice.
Well, one way could be through some sort of magical cross - over event. Maybe the gods in the Percy Jackson universe notice Naruto's great power and determination from his own world. They decide to bestow god - like powers on him, perhaps seeing him as a worthy addition to their pantheon. Another possibility is that Naruto somehow stumbles into a magical portal that connects his world to the Percy Jackson world and there, he undertakes a great quest that earns him god - hood.
He might have incredible new powers. For example, he could control not only water but also other elements from the pantheon he crosses over with. He could use his new godly status to protect more than just the demigods. Maybe he would be able to create new realms or change the rules of existing ones.
Well, he might gain incredible cosmic powers. He could have the ability to manipulate space, time, and matter at will. His appearance might change to something more otherworldly, with a glowing aura perhaps. And he could have a new level of wisdom, seeing the grand design of the universe.
He might gain new powers like controlling all aspects of water, not just the sea. He could also have the ability to create new sea creatures.
A really cool aspect of a Percy Jackson and LOTR crossover fanfiction could be the character interactions. Annabeth, with her strategic mind, could collaborate with Gandalf. She might learn a great deal from his wisdom and long - experience in Middle - earth. On the other hand, Legolas could be fascinated by the archery skills of the Apollo - related demigods. The cultural differences between the two worlds would also add depth to the story. The demigods, coming from a modern - ish world (compared to Middle - earth) would have different values and ways of thinking, which could lead to both conflicts and growth for the characters involved.
Well, in a Spider - Man Flash crossover fanfiction, there could be an epic race between the two. The Flash could be testing his speed against Spider - Man's agility and web - slinging skills. Maybe they start as rivals but end up teaming up to face a common enemy like a super - fast villain that only their combined powers can defeat.
It could be about Percy imagining himself with Spider - Man's powers. He might daydream about swinging through New York City instead of battling monsters in the mythological realms. He could also be envious of Spider - Man's ability to blend into the human world more easily than he can as a demigod.
