Percy would likely be very critical of their lifestyle. He comes from a world where family is important and they support each other in the face of danger. The Dursleys, on the other hand, seem to shun anything out of the ordinary and are unkind to Harry. Percy might try to show them a different way of living, with more love and acceptance, though they probably wouldn't listen.
In fanfiction, if Percy Jackson meets God, it could be a really intense encounter. God might test Percy's abilities and loyalty. Maybe Percy would be in awe at first, but then his demigod nature would kick in and he'd stand his ground, ready to face whatever God throws at him.
Well, one possibility is that Percy Jackson, with his water - based powers, and Hercules, known for his great strength, could find themselves in a situation where they need to combine their skills. For example, if there's a huge flood caused by a malevolent god and the only way to stop it is for Hercules to hold up a collapsing dam while Percy uses his powers to redirect the water. Also, their personalities could clash or bond. Percy is more of a modern - day hero with a sense of humor, while Hercules is a classic hero. This could lead to some interesting exchanges between them as they get to know each other and learn from each other's ways of being a hero.
Percy would probably be cautious. He's been through a lot with the Greek gods, and he knows how powerful divine beings can be. So, he'd approach this new encounter with wariness.
Well, Percy could use his water powers to help the Agents in a situation where they face a threat related to water, like a flood created by a villain. Maybe he'd be initially mistrusted by the Agents, but then prove his worth.
Well, they might team up to fight a common enemy. Maybe a new and powerful monster that neither of their worlds has seen before. Their different powers and skills could combine in interesting ways.
Well, they could go on an amazing adventure together. Percy could use his water - controlling powers and Star could use her magic wand. Maybe they'd fight some mythical creatures that are a mix of the Greek mythology ones Percy knows and the magical ones from Star's dimension.
It's really hard to say who would be more powerful. Percy has his unique powers related to water and being a demigod son of Poseidon. He can control water, which gives him an edge in many situations like battles at sea or near large bodies of water. However, Hercules is known for his superhuman strength. He has accomplished incredible feats of strength like slaying the Nemean Lion. In a direct physical fight on land, Hercules might seem more powerful, but Percy's powers are more versatile and can be used in creative ways.
One possible plotline could be a quest. They are both sent on a mission, either by the gods in Percy's world or the deities in Sadie's world, to retrieve a powerful artifact that has been lost between the two mythologies. Along the way, they face many challenges and learn to trust each other.
There are some great 'Thor meets Percy Jackson' fanfictions. Some focus on the culture shock between them. Percy being used to the Greek world and Thor from Asgard. They often have humorous exchanges as they learn about each other's worlds and powers.
