He could also have some humorous interactions. Maybe he tries to introduce some of his modern - day concepts to the Spartans, like the idea of pizza. The Spartans would be confused but intrigued. And in return, the Spartans would show him their way of life, which is very different from what Percy is used to in the modern demigod world. This exchange of cultures could lead to some interesting moments during the battle preparations.
Percy would most likely form alliances with the historical figures. He would see that they are all fighting for a common cause, to defend their land. He might use his powers to help them in ways they couldn't have imagined. For instance, he could use his water powers to create barriers or distractions for the enemy, while the Spartans use their brute force and military tactics. Together, they would create a formidable defense against their foes.
One possible plot twist could be that Percy discovers a hidden power within himself during the battle. Maybe he realizes he can control not just water, but also the heat from the hot springs in Thermopylae, using it to his advantage against the enemies. This new power could turn the tide of the battle in an unexpected way.
Azula would probably try to use Percy at first. She might see his powers as something she could control or use for her own gain. However, Percy is not one to be easily manipulated. He would resist her attempts, which could lead to some intense verbal sparring between them. As time goes on, they might develop a grudging respect for each other. For example, Percy might admire Azula's strategic mind, and Azula could respect Percy's loyalty to his friends.
Percy would probably be curious about Katara's water - bending. He might ask her to show him some cool moves. Katara, on the other hand, would be interested in Percy's ability to control water in a different way. They would likely start off a bit cautious but quickly become friends as they realize they both have a strong connection to water.
In a fanfiction, Percy Jackson and the Avengers' interaction would be complex. Percy comes from a world of gods and monsters, and the Avengers from a world of super - science. At first, there could be misunderstandings. Percy might think the Avengers are too full of themselves, and they might think he's a bit of a wild card. However, as they face challenges together, like a group of mythical beasts invading New York, they'd learn to rely on each other. Percy could use his ability to communicate with sea creatures to gather intelligence, while the Avengers use their powers to fight on land. Their combined efforts would make them a formidable team.
Percy would probably be in awe of Aquaman's pure Atlantean powers at first. He might be a bit jealous as well, since he's just a demigod with limited underwater abilities compared to Aquaman. Aquaman, on the other hand, would be curious about Percy's connection to the Greek gods. They would start off a bit cautious around each other, but as they face common threats in the ocean, like pirates using dark magic or sea creatures gone berserk, they would gradually start to trust and rely on each other.
Percy could use his skills in combat and his powers over water to interact with dinosaurs. For example, if a dinosaur attacks him near a water source, he could create a large wave to knock it back or use the water to make himself move faster to avoid its attacks. He might also try to communicate with them if he discovers some kind of ancient magic or power that allows him to do so.
They might start off as rivals. Percy could see Scott as a wild and unpredictable werewolf, while Scott might view Percy as a stuck - up demigod. But as the story progresses, they'd learn to respect each other's abilities.
They would probably start by sizing each other up. Percy would be curious about Jason Todd's gadgets and skills from the Gotham world. Jason Todd, in turn, would be interested in Percy's powers over water and his demigod status. Their interaction could involve some banter and a bit of posturing at first, but eventually, they'd realize they can learn from each other.
He'd probably be cautious at first. Given his experiences with the Greek gods, he'd know that gods can be unpredictable. He might start by observing the Celtic gods' behavior. Maybe he'd try to find common ground, like their connection to nature or their role in the cosmos.
