Maybe Percy unknowingly breaks some ancient and very strict laws of the Gods. For example, he might interfere with some sacred rituals or places that are off - limits to mortals, even demigods like him. In the fanfiction world, the Gods could be very unforgiving when it comes to such violations and decide to kill him as a result.
Yes, it is quite popular. Some fans like to explore alternate storylines where Percy takes extreme actions like this. It adds a new level of drama and reimagines the power dynamics in the Percy Jackson universe.
Percy would initially be shocked and a bit scared. But then, his sense of responsibility would kick in. He would start to train himself to use the powers effectively. He might seek out the help of some of the more benevolent gods or goddesses who could give him advice. He would also have to deal with the envy or fear of others. However, Percy's loyalty and good heart would guide him to use the powers for the greater good, like protecting the demigods and the world from new threats.
He could go on adventures to the far reaches of the Underworld. With all the gods' powers, he might be able to access areas that were previously off - limits. He could also journey to the homes of the gods and goddesses to learn more about their powers and how to use them better.
Annabeth Chase would most likely be one of his allies. She has always been by Percy's side, and she shares his sense of justice. If Percy decides to take on the gods, she would be there to support him with her intelligence and strategic thinking.
His mother, Sally Jackson, could play an important role as an ally. She has a strong will and has always been there for Percy.

Some of the water nymphs might help Percy since he has a connection to water.
Well, in some fanfictions, Zeus and Poseidon have a 'divine argument' over who has the better beard. It's really silly but makes for a great read.

Another theme is the creation of new quests. Fanfiction writers often come up with unique quests for Percy and his friends. These quests can involve different mythologies or new challenges that are not in the original books. For instance, a quest that takes them to a hidden realm full of forgotten gods.
