The relationship with the gods would also be different. Gods who were previously indifferent to him might start to take notice. Some gods might see him as a threat, especially if they think he could use his combined blessings to challenge their authority. Others might try to use him for their own purposes. And Percy himself would have to navigate these new political and power - related interactions with the gods.
His relationships with other demigods would likely change. They might view him with a mixture of awe and envy. Some might be drawn to him because of the newfound power, while others could be afraid. His friends like Annabeth would need to adjust to this new, more powerful Percy. With the blessings, he might seem a bit more distant as he grapples with his new abilities.
In terms of his relationship with his enemies, they would be more cautious. Monsters might be more hesitant to attack him, knowing that he has the blessings of Nyx and Uranus. However, this could also attract more powerful and cunning enemies who would see him as a worthy opponent to defeat. His relationships would become more complex and full of new dynamics as a result of these blessings.
He would probably become an even more formidable figure. With Nyx's blessing, he could have enhanced senses during the night, making him a better fighter in the dark. And from Uranus, he might receive a boost in his leadership abilities. Since Uranus was an important god in the Greek pantheon, this could give Percy more influence among the demigods and gods alike. He could be seen as a special agent of change, with the combined powers of these two deities.
With his friends at Camp Half - Blood, Percy might become a bit of an outlier. His connection to Zeus through the blessing could make some of his friends who are more closely tied to Poseidon or other gods feel a bit uneasy. However, it could also earn him respect from those who admire Zeus' power. Percy would have to work hard to maintain his friendships while dealing with this new dynamic.
His relationship with Annabeth could be strained. She might be initially afraid of the changes in Percy due to his demon half. However, over time, as she sees that he's still the same Percy at heart, they could work through it and their relationship could become even stronger as they face this new challenge together.
His relationship with Annabeth would definitely be affected. She might be a bit wary at first, since Nyx is such an unknown and powerful entity. But she would also be there to support Percy as he figures things out.
The blessings can also open up new paths for his adventures. Say he gets blessed by Hermes. He might be able to travel to places that were previously unreachable or travel at a much faster speed, which could lead to him exploring new regions of the mythological world and uncovering hidden secrets.
Romantic relationships can also be a part of it. In some fanfictions, the daughter of Nyx might develop feelings for Percy over time. This could be a slow - burning romance where they first become comrades in arms, and then as they understand each other better, deeper feelings start to emerge. Their relationship could be complicated by the fact that she is from a different and more mysterious lineage compared to Percy, which adds an extra layer of intrigue and tension.
The balance in nature would be disrupted. Artemis is the goddess of the hunt, the moon, and nature. Her death could cause strange phenomena in the natural world, like animals going wild or the moon's cycle becoming erratic. This would not only affect the demigods but also mortals who depend on the stability of nature.
Percy's personality would likely become more hardened. Growing up with assassins, he'd see a lot of violence and death. This would make him less trusting and more cynical. He might not be as quick to make friends as he was in the original story. However, his loyalty to those he does trust would be even stronger, like the loyalty assassins have to their comrades. Also, he'd be more disciplined, following the assassin code he was raised with.
His relationship with Annabeth would be very different. Annabeth might be initially scared of Percy because of his dark lineage. She would be cautious around him as she is used to the more 'typical' demigods. Percy, on the other hand, might feel isolated from her because he knows she is wary. His friendships with the other demigods at Camp Half - Blood would also change. Some might avoid him, while others might be intrigued by his new powers and origin. Grover, for example, might be torn between his loyalty to Percy and his fear of what Percy could become.
His relationship with Annabeth would likely become more complex. She might be a bit worried about Percy's new powers and what they could mean for his safety and their future together. But at the same time, she would be there to support him as always.
