In this fanfiction, Annabeth would be a strong ally. Their relationship would be more complex but still based on mutual respect and admiration. Since Percy is a god, she could rely on his power and knowledge more. Additionally, Chiron, with his wisdom and experience, would also side with Percy. Chiron could guide Percy in using his new godly powers in a proper way.
If Percy was born a god, the minor gods might see him as an ally. They are often overlooked by the major gods, and Percy, being different from the typical Olympian gods, could be more sympathetic to their causes. He could also gain allies among the magical creatures. For example, the centaurs other than Chiron or the nymphs. They would be drawn to his power and his more inclusive nature compared to the other gods.
His mother, Sally, would surely be one of his allies. She has always been there for him. Also, Grover could be his ally as they have a long - standing friendship. Grover might see Percy as an even greater protector of the nature spirits now that he's a god.
Some minor gods related to the earth like Demeter could be allies. She has her own powers over the earth and could teach Percy some of her techniques. Also, the nymphs, such as the water nymphs and the tree nymphs, could be allies. The water nymphs could help with the water sources within the earth (like underground rivers) and the tree nymphs could help Percy take care of the forests. And let's not forget the pegasi. They could be used for transportation when Percy needs to quickly travel across his earthly domain.
His friends from Camp Half - Blood like Annabeth could be his allies. Annabeth is smart and strategic, and she would be able to offer valuable advice as Percy goes through the process of becoming a minor god.
The Cyclops Tyson could be an ally. He has a strong bond with Percy and his strength could be a great asset. In a fanfiction where Percy is the God of Light, Tyson could be like a protector of Percy's light - based temples or strongholds. Also, the sea creatures that Percy has befriended over the years might come to his aid. Since Percy has his roots in the sea and now has light powers, they could work together in a unique way, like the sea creatures using their natural abilities to help spread Percy's light across the oceans to keep dark sea - based threats at bay.
Perhaps it could be a new evil force created as a result of Percy's sudden god - born existence. His new - found power could have unbalanced some ancient magic or prophecy, and this new evil entity rises to oppose him and restore the old balance. It might be a being made of dark magic that has a vendetta against Percy for disrupting the natural order of things.
Grover could be a strong ally. He's always been Percy's friend and would likely stand by him even with this new role. Grover's ability to sense things could be helpful in complementing Percy's unseen powers. Another potential ally could be Chiron. Chiron has a wealth of knowledge and would probably guide Percy in understanding and using his new powers.
Chiron could be an important ally. With his vast knowledge of the demigod world and its history, he could guide Percy in making just decisions. Also, some of the minor gods who have been overlooked in the past might side with Percy, seeing him as a champion of a more fair and inclusive form of justice.
In 'Percy Jackson Born a God Fanfiction', Percy could have a very different upbringing. Since he's born a god, he might not face the same kind of discrimination or danger that normal demigods do. He could be raised in Olympus, learning the ways of the gods from a very young age. His relationships with other characters would also be transformed. For example, Annabeth might view him more as an equal to the gods she admires rather than just a fellow demigod. His adventures would likely be on a much grander scale, perhaps involving saving the entire universe in a more direct way compared to his demigod self.
His life would change drastically. He would be a being of immense power. He would no longer have to fear the wrath of the Olympians as he would be on a similar or even higher level. He could shape the world as he wished.
Annabeth would most likely be his ally. She has been with him through thick and thin, and her wisdom would be invaluable as Percy becomes a god. Grover could also be an ally, using his nature - related powers to help Percy in different situations. Another possible ally could be Nico di Angelo. With his control over the dead, he could provide unique assistance, especially when it comes to dealing with the darker aspects of the godly world.
Poseidon is a likely candidate. Since he is Percy's father in the original series, it would make sense for him to take a more active role in raising Percy. He could teach Percy all about the ocean, its secrets, and how to use his water - related powers more effectively.
