How would Percy Jackson and Black Widow interact in a fanfiction?

Percy's character might become more stealthy and calculating. He'd probably learn to analyze situations more like Black Widow does. Instead of just charging into battle, he'd think about the best approach first.

The characters would likely start off with some level of distrust. Percy, being a demigod, is used to dealing with his own set of rules and powers. The Black Panther, as the protector of Wakanda, is very protective of his kingdom. For example, when Percy first arrives in Wakanda, T'Challa (the Black Panther) might be on guard. But once they realize they are both fighting for good, they could start to exchange fighting techniques. Percy could show how he uses his sword and powers in combat, while T'Challa could teach Percy some of the Wakandan martial arts moves.

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.

Percy's power over water could potentially be combined with Sirius' Animagus form. For example, Sirius in his dog form could swim faster in water controlled by Percy. Also, Percy could use water to create distractions or barriers in a fight, while Sirius could use his werewolf - fighting skills and speed to take on enemies that get past Percy's water defenses.

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.

A possible main antagonist could be a new character created specifically for this fanfiction. A scientist who has somehow managed to combine Greek magic with Hydra technology. This character could be creating powerful hybrid creatures that are causing havoc in both Percy's world and the Marvel universe. Percy and Black Widow would need to put aside their differences and work together to stop this mad scientist.

One idea could be that Black Widow is somehow transported into the Percy Jackson universe. Maybe she has to team up with Percy and his friends to defeat a common enemy. Since she has her combat skills and spy training, she could offer a different perspective on battle strategies compared to the demigods.
