Well, Percy's new powers could include the ability to communicate with creatures of the night in a way he couldn't before. Maybe he could call upon the help of shadowy beasts or entities that are associated with Nyx and Erebus. His strength might also be tied to the level of darkness around him. In a pitch - black place, he could be extremely powerful, while in bright sunlight, his powers might be somewhat weakened.
If Percy was the son of Nyx and Erebus, his powers would be a far cry from his Poseidon - granted ones. He might be able to create illusions using shadows, making it seem like there are threats or allies where there are none. He could also have a form of 'dark sight', being able to see clearly in the darkest of places. His powers would be more about stealth, mystery, and the manipulation of the unseen elements of the world, which is a huge departure from his more straightforward water - based abilities.
His powers would likely be much darker. He might have the ability to manipulate shadows like Nyx, using them to hide or even attack. And from Tartarus, he could have the power to cause earthquakes or open up chasms in the earth. He could also have a natural resistance to the harmful effects of the Underworld, such as the poisonous gases and the draining of energy that normal demigods experience.
If Percy were the son of Poseidon and Hera, his powers would be quite unique. His water powers could be enhanced in a different way. Maybe instead of just controlling water, he could transform water into different substances related to Hera's domain, like turning water into a fertile soil - like substance for plants to grow. His leadership skills would be off the charts. He could use his Poseidon - given strength and Hera - influenced charisma to lead not just demigods, but also other mythical creatures. He might also have the power to protect a place or a group of people in a more profound way, like creating a shield made of both water and a golden energy that represents Hera's protection.
His powers might become more related to the night. He could gain the ability to see clearly in the dark, like having night vision. Maybe he could also manipulate shadows, using them as a form of defense or offense. For example, he could create shadowy constructs to fight his enemies.
Well, instead of summoning water or having a connection with the sea, he might have the power to shift shapes, a common ability associated with Loki. He could turn into different animals or even other people to gain an advantage in a fight or to infiltrate an enemy's stronghold. Also, his power over fire could be enhanced, as Loki has some association with fire in Norse mythology. He could use this to create distractions or attack opponents from a distance.

Well, if Percy was the son of Loki and Poseidon in fanfiction, his powers would be a really wild mix. He might have Poseidon's control over water, but with a Loki - like trickster twist. For example, he could create illusions in the water, making it seem like there are sea monsters when there are none to deceive his enemies. He could also use Loki's shape - shifting ability while in the water, perhaps turning into a mermaid - like form with a mischievous glint in his eyes. His power over water could also be used in more devious ways, like creating whirlpools that suck in his foes and then spit them out in a different location, all while laughing like Loki would.
Well, in the original Percy Jackson stories, Percy has powers mainly related to water as the son of Poseidon. But in this fanfiction with Hestia as his mother too, he might have an added connection to fire or the concept of home. So, he could potentially have the ability to control the temperature of water, like making it boil or freeze instantly, which combines his water powers with a bit of the hearth - related powers. He might also be able to create a sort of protective shield around himself and his friends that has the properties of both the ocean's strength and the warmth and safety of the hearth.
Percy could have the power to manipulate the coldness that is often associated with the Underworld. He could freeze his opponents or create ice - like structures out of the cold energy. This would be different from his water - based powers in the normal story. Also, he may have a stronger connection to the gems and precious metals that are found in the Underworld, being able to sense them and even use them in some way for his benefit.
His powers would likely be a blend of Greek and Norse elements. For example, he might still be able to control water like in his Greek demigod abilities, but also have some connection to ice or snow from the Norse side. Maybe he could freeze water in a way that's more related to Norse frost magic.
His powers would be different in that he could manipulate the emotions of those around him in a way related to Dionysus' influence on celebration and revelry. For example, he could make an enemy feel over - confident and sloppy in battle by making them think they are at a party and there's no real danger. Other demigods don't have this kind of emotional manipulation power.
