One way could be to describe the shock on his classmates' faces. For example, 'Percy blurted out a Greek phrase in the middle of class, and everyone's jaws dropped.'
In a fanfic, it could be that Percy is trying to communicate secretly with another demigod in the class. So he speaks Greek in a hushed tone, thinking no one else will understand. But then someone overhears and starts to suspect that there's something strange about Percy. You could describe the classroom setting, the reactions of the other students, and how Percy tries to cover up his mistake or if he decides to come clean about his demigod identity depending on how the plot of the fanfic is supposed to develop.
Perhaps Percy would use his knowledge of Greek gods and goddesses to impress the teacher. He could share some unique insights about a particular deity that are not commonly known. This could lead to him getting special privileges in the class, like being excused from a difficult assignment or getting extra credit.
His water - controlling powers could cause some interesting situations. For example, if there was a leaky faucet in the classroom, he could accidentally make the water spray everywhere in a fit of distraction. Or he could use it to create a cool mist during a hot day to cool down the classroom, much to the surprise of his classmates.
Well, he might get some strange looks from his classmates. Some might think he's just showing off or being weird. But if there are any other demigods in the class, they could be secretly impressed or even a bit envious that he's so casually using Greek.
Another option for the main antagonist could be a spirit of an ancient Greek scholar who was banished from the world of the gods. This spirit haunts the Greek class and tries to possess Percy because he sees Percy as a way to get revenge on the gods. It causes chaos in the class, making it difficult for Percy to focus on his studies and also putting his friends at risk.
Well, it could be about Percy using his Greek language skills to communicate with ancient Greek monsters in a more in - depth way. Maybe he discovers some long - lost secrets that can only be understood through the original Greek language.
First, know the source material well. You need to be familiar with all the characters, their personalities, and the world of Greek and Roman mythology in the Percy Jackson series. Then, come up with an original plot. Maybe something that could have happened but wasn't explored in the original books. For example, what if Percy had to deal with a different set of gods from a far - off part of the mythological world? Also, focus on good character development. Make the characters grow and change in a believable way throughout your fanfic.
One common way to find Romans in Percy Jackson Greek - related fanfic is to look for tags or keywords. Search for terms like 'Roman demigods' or 'Greek - Roman crossover'. This will lead you to fanfics that specifically deal with the relationship between the two. Another aspect is that in these fanfics, the power dynamics between the Greek and Roman gods can be explored differently. Maybe the Roman gods are more strict in their rule in some fanfics compared to the Greek gods, and this affects how the demigods from both sides interact.
One great 'Percy Jackson Greek and Romans Fanfic' is 'The Son of Neptune Redux'. It offers a fresh take on the story, with new adventures for Percy and his friends. The character development is really well - done, and it stays true to the spirit of the original series.
One way could be that it's a gift from a minor god. Maybe a god associated with fire secretly blessed Percy, giving him this power.
Perhaps Percy could have a dream during Greek class about an upcoming prophecy related to the class. In the dream, he sees that a certain ancient Greek artifact hidden in the school is going to be discovered, and it will either bring great danger or great power. So, he spends the rest of the class trying to figure out how to stop or find it first. Also, he could get into an argument with a teacher who doesn't believe in the real existence of the Greek gods, but Percy has to prove it without revealing his true identity as a demigod.
