Who are the possible characters in 'Percy shows off his powers fanfic'?

In the fanfic, Percy might show off his powers in a competition among demigods. He would display his combat skills along with his unique powers, like being able to communicate with sea creatures to gain an edge in the contest.

In certain fanfictions, Percy shows his powers by summoning massive tidal waves that are much larger than what we've seen in the official books. This could be to defend a large area from an invading army. He may also use his power to purify polluted water sources, which is a new aspect not explored much in the original series. This helps the local people and shows his growing control over his powers.

It's likely that Chiron, the centaur, is also a main character. He has a wealth of knowledge and experience and can guide Percy and the other demigods in using their powers effectively to protect the camp. He might also be involved in training them and preparing for different types of threats that Percy's powers need to counter.

Nico di Angelo is another popular character in these fanfics. His control over the dead and shadow - traveling abilities offer a lot of room for creativity. Fanfic writers often give him new powers or expand on his existing ones, like making his control over the dead more powerful or adding new elements to his shadow - traveling. His brooding and mysterious nature also makes him an interesting character to write about in the context of powers.

In some fanfics, Percy's powers could be used in a more stealthy way. For instance, he could use water to create mirages or illusions to deceive his enemies. This would require a great deal of control over his water - based abilities and show his growth as a character. It also allows for more complex and exciting plotlines in the fanfic world.

Annabeth could be one of the main characters interacting with him. She might tease him about taking his shirt off, or she could be concerned if he's taking it off because of an injury. Their relationship is complex, and this situation could add a new layer to it.

In this fanfic, Harry is the main character. However, we could also expect to see Dumbledore making an appearance. Dumbledore has always been a guiding figure for Harry, and in a story about Harry showing his power, Dumbledore might offer some wisdom or crucial information. Neville could also be a key character. He has his own growth in the original series, and in this fanfic, he could be inspired by Harry's power and contribute to the overall plot in some way.

There could be an old gardener who mentors Percy. The gardener might teach Percy all about the plants in the garden, their needs, and how to keep the garden thriving.

Obviously, Percy is the main character. There could also be his family members who might react in different ways to his being born a monster. Some might be accepting, while others could be horrified.

There could be his friends like Annabeth. She might be the one who first notices Percy's change and helps others to see him in a new light as well.
