The blessing could make Percy more confident. Knowing that a major god like Apollo has blessed him gives him an extra boost. He might take on more challenges without hesitation, believing that he has the favor of the gods on his side.
One possible plot could be Percy getting a special power from Apollo's blessing. For example, he might gain the ability to heal faster, which would be really useful in his battles. He could use this new power to save his friends in a dangerous situation, like when they are facing a powerful monster and his friends are severely injured.
His character would become more confident in his artistic abilities. Apollo is the god of many arts, so Percy would likely be exposed to music, poetry, and painting. He might be more flamboyant in his actions and speech, as Apollo has a certain charm. For example, he could start using more flowery language when talking to his friends or enemies.
Percy's character would likely become more versatile. He'd start to incorporate Apollo's traits like confidence and a love for the arts. His power set might expand to include things like healing, which is associated with Apollo. He'd also become more in tune with the sun and light, which could change his overall perspective on things.
Well, a new haircut could also be a sign of Percy's growing confidence. Maybe he was self - conscious about his old look and the new haircut gives him the boost he needs. It could make him more outgoing in his interactions with other demigods and mortals. He might be more willing to take risks and step out of his comfort zone. For instance, he could be more likely to approach new quests or challenges with a new - found confidence that stems from his new appearance. And it could also affect how others perceive him, which in turn affects his own self - perception and character development.
Percy would likely become more confident in his powers. As Apollo's brother, he might gain access to some of Apollo's knowledge, which could make him a better strategist. For example, he could use Apollo's understanding of the sun's patterns to his advantage in battles.
In some fanfictions, Percy might use his friendship with Apollo to get some unique items. For instance, Apollo could give him a special arrow that can travel through water without getting wet, which Percy could use in his future battles or quests.
It could strain their relationship further. Yelling usually indicates a breakdown in communication and respect. If Artemis yells at Apollo, he might become defensive and retaliate, leading to more animosity between them.
One great fanfiction could be about Percy and Apollo going on a quest together. Maybe they have to retrieve a lost musical instrument of Apollo that has the power to control the tides. In this fanfic, Percy's water powers and Apollo's sun - related abilities would make for an interesting combination.
Poseidon's possessiveness can also shape Percy's view of relationships. He might become more cautious about getting too close to others or letting them have too much influence over him. Since his father is so possessive, Percy could be afraid of losing his freedom in other relationships. At the same time, he might also learn to value true friendship and loyalty more, as those are things that can't be controlled by Poseidon's possessiveness.
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.
