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.
When Percy is blessed by the gods in fanfiction, it often means that his adventures take on a different tone. He may no longer be just a regular demigod struggling against the odds. Instead, he becomes a more significant figure in the grand scheme of things. His actions could have larger consequences, not just for himself but for the entire demigod world. For example, a blessing from Hades might give him the ability to control the dead to some extent. This would not only be useful in battles but also in dealing with the afterlife - related problems that might arise during his adventures. And this new power would attract more attention, both positive and negative, from different factions in the mythological realm.
He might gain extraordinary powers. For example, he could get enhanced strength from Ares that allows him to defeat powerful monsters with ease. Or he might receive wisdom from Athena that helps him solve complex problems and outwit his enemies.
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.
One interesting plot could be Percy getting a new and extremely powerful ability blessed by a previously unknown god. This could lead to him having to face a new set of challenges and enemies that are specifically drawn to his new power.
Well, there could be Percy going on quests with the gods by his side. Maybe they help him face new and more powerful monsters that he couldn't handle alone. For example, fighting a giant that has been awakened by an ancient curse.
Chiron, the centaur trainer at Camp Half - Blood, is often included. He has a vast knowledge of the gods and their ways, so he can guide Percy through understanding the nature of his blessings. He can also help Percy train to control any new powers that come with the blessings. Additionally, some fanfictions might include new or minor characters who are either the cause of the blessings or are affected by Percy's new - found status after being blessed by the gods.
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.
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 could also be very sad. He has so many memories and relationships at the camp. He might go into a state of depression for a while, not knowing where to go or what to do next. But then, he would probably start to think about how to get back in or how to make things right. He might start looking for evidence to clear his name if he was wrongly accused. He could also look for new allies outside of the camp who could help him in his situation.
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.
Perhaps the blessings make Percy a target. Other demigods or villains might be jealous of his new status. He then has to deal with the envy and threats while also trying to figure out how to fully utilize the blessings in a positive way. For instance, the gods' blessings might come with some sort of side - effect that he has to overcome as well.
