His relationship with Annabeth would be very strained at first. She might be very suspicious of him and his motives, given his relation to Kronos. But as she sees Percy struggling against the dark influence, she could come to his side and help him. Their relationship would then become deeper as they face this new challenge together.
His relationship with the gods would be super interesting. The gods would be very wary of him. Zeus, in particular, would probably want to keep an eye on him or even try to eliminate him. But some of the more benevolent gods, like Poseidon (even though he's not Percy's father in this fanfiction), might give him a chance. Percy would have to navigate this tricky political situation among the gods while also trying to find his place in the world.
With Kakashi, Kakashi would be very cautious at first. He'd need to understand what this new development means for Naruto and the village. But as he sees Naruto trying to handle it responsibly, he would offer his guidance as he always has, but with an added layer of concern for the implications of Naruto's relation to Kronos.
The relationship with Poseidon would be extremely complicated. Poseidon would be torn between his love for Percy and his fear of what Percy could become as Kronos' twin. He might try to distance himself from Percy at first, which would deeply hurt Percy. On the other hand, Percy's relationship with some of the minor gods might improve. Since they are often overlooked by the major gods, they might see Percy as a potential ally in changing the status quo. Percy's relationship with Luke, if he were still alive in this fanfiction, would also be interesting. Luke might try to use Percy's connection to Kronos to his advantage, but Percy would have to be careful not to be manipulated by Luke.
His relationship with Annabeth would be really strained. Annabeth is a firm believer in the gods, and if Percy is the son of Kronos, she would be very suspicious and probably feel betrayed. She might even try to fight Percy at first, thinking he's a threat to her and her friends.
If Percy is the son of all gods in fanfiction, his relationships would change drastically. His relationship with his mother would be different. She would have to come to terms with her son's even greater significance and the new dangers that come with it. His interactions with the minor gods and goddesses would also be different. They might see him as an opportunity to gain more influence or as a threat to their own positions. His relationship with other demigods from different cabins at Camp Half - Blood would shift. Some might try to get closer to him for power, while others might distance themselves out of fear. And his relationship with the mortal world would be more tenuous as his godly side becomes more pronounced and he has to balance his two worlds even more carefully.
With his friends from Camp Half - Blood, things would be a lot more complicated. Some might look up to him as someone with extraordinary power, but others might be jealous or feel threatened. His relationship with Chiron would also change. Chiron would have to be extra careful in guiding Percy, knowing that his actions could have far - reaching consequences due to his unique parentage. And when it comes to his enemies, like the monsters, they might be even more determined to defeat him, seeing him as a greater threat to their plans than before.
His relationship with Annabeth would likely be more complex. She might be initially worried about the new powers Percy has from Gaia. There could be some jealousy or fear that he's becoming too different. With his friends from Camp Half - Blood, some might look up to him more because of his even greater potential, while others could be intimidated. His relationship with the Poseidon cabin would also be different. They might see him as more of an enigma now that he has this additional connection to Gaia.
His relationship with Annabeth would definitely be different. She is used to Percy being a son of Poseidon, but now as the son of chaos and order, he might seem more unpredictable. She would have to learn to trust his new instincts which are influenced by both chaos and order. For example, in battle, Percy might make decisions that seem risky (from chaos) but are actually calculated (from order) in a way Annabeth doesn't immediately understand.
Well, when it comes to Percy's relationships in this fanfiction scenario, it's really a big shift. His bond with his mother would be affected as she tries to understand this new part of her son's identity. His relationship with Grover would have an interesting turn. Grover might see Percy as even more of a protector figure now, but also be concerned about the changes. And Percy's relationship with the minor gods would change too. They might approach him, hoping to gain some favor or protection through his link to Ouranos. Overall, Percy's relationships would be in a state of flux, with everyone trying to figure out how to interact with him in this new role.
Well, with his friends from Camp Half - Blood, Percy would be sort of an outlier. His friends might be a bit jealous of his powerful heritage at first. But as they get to know him better, they realize that he has his own set of problems. For example, he might be constantly watched by the gods more closely than other demigods because of his parentage. His relationship with Chiron would also change. Chiron would have to figure out how to train Percy with his unique combination of powers. And when it comes to the villains in the story, they might target Percy more because they see him as a threat due to his powerful parents. So, overall, his relationships would be in a state of flux and constantly evolving because of his special background.
