In a fanfiction, their interaction could be really interesting. Percy Jackson is a hero who has faced many challenges in his own world. Green Lantern is also a hero but from a completely different universe. When they meet, Percy could be curious about the Green Lantern's power ring. Green Lantern could be interested in Percy's relationship with the gods. They could exchange stories about their battles and then decide to work together to face a new threat that is affecting both their worlds.
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.
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.
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 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.
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.
They could interact in a way that combines their different skills. For example, Percy could use his water - based powers to help Lady Sif in situations where she needs to cross large bodies of water or deal with water - based enemies. Lady Sif could share her knowledge of Norse magic and weaponry with Percy. Their interactions could also be filled with cultural exchanges. Percy could introduce Lady Sif to things like blue food from Camp Half - Blood, while she could tell him stories of the great battles in Asgard. This would create a unique bond between them as they learn from each other.
Percy would probably be a bit in awe of Maria Hill's no - nonsense attitude and her knowledge of modern technology and warfare. He might crack some jokes about how different it is from his world of swords and sandals. Maria Hill, on the other hand, would be initially skeptical of Percy but would soon come to respect his abilities. For example, Percy could show off his water - bending powers to her, and she would be impressed and start to think of ways to use those powers in their combined efforts.
They could be competitive at first. Each thinking their own powers and heritage are superior. But then they'd find common ground in their shared experiences as heroes in their respective mythologies.
Percy's powers are based on water and his demigod abilities. Thanos has the power of the Infinity Stones. If they were to interact, Percy's water could potentially disrupt Thanos' use of the Power Stone's energy blasts. For example, water could absorb or deflect the energy.
