In many Percy Jackson fanfictions, time travel often works through magical artifacts. For example, a special time - turning hourglass might be used. It could be a powerful object left behind by an ancient god or goddess.
To write a great 'Percy Jackson Time Travel Fanfiction', think about the consequences of time travel. If Percy changes something in the past, how will it affect the present and future?

And don't forget to include the humor and adventure that are typical of the Percy Jackson series.
It could be Luke. Even in a time - travel scenario, Luke's bitterness towards the gods might lead him to betray Percy. He could use time - travel to his advantage, perhaps making deals with past versions of enemies to stop Percy from achieving something that would benefit the gods.
He could be portrayed as a time - bender, having the power to not only travel through time but also manipulate it to some extent. For example, he could slow down time during battles in the past to gain an advantage.
Percy could change the past and accidentally create a new future. For example, if he stops Chronos from a certain event, it might have unforeseen consequences for the demigod world he knows. He might return to his own time to find that his friends are different or that Camp Half - Blood has changed drastically.
Percy is impulsive. So in time travel, he might rush into situations without fully thinking about the consequences. For example, he could see a monster from Greek mythology in a different time period and immediately attack it, not realizing that this action could change the future. Artemis, on the other hand, is more calculating. She would likely try to analyze the situation first, like figuring out how the time period they are in affects the monster's behavior and power.
Well, perhaps in this fanfiction, Percy Jackson is sent on a time - travel mission by the gods. But he discovers that his friends or allies have betrayed him. Maybe they've made a deal with an enemy from another time period. For example, they could have promised to help Kronos in the past in exchange for power in their own time. Percy then has to not only deal with the time - travel chaos but also face the betrayal and find a way to set things right.
