In a Percy Jackson time travel harem fanfiction, Percy could time - travel to a time when the Titans were still ruling. He befriends some female Titans who are intrigued by his modern - day demigod ways. Along with some female demigods from different points in history that he also meets during his travels, they form an unlikely group. Their main goal could be to stop a future threat that Percy knows about from his own time, but they also have to deal with the complex relationships within the harem.
Well, Percy might time travel to a parallel dimension in a harem fanfiction. In this dimension, the rules of the Percy Jackson universe are a bit different. He encounters a group of female characters who are all attracted to his unique abilities. There could be a version of Annabeth from this dimension who is more aggressive in her pursuit of Percy, along with other new female characters. They end up on a quest together that is related to the time - travel anomaly that brought Percy to this dimension.
One interesting plot idea could be Percy traveling back in time to the era of the Greek gods' creation. He could witness the birth of the first gods and goddesses and perhaps even play a role in some of the early events. Another idea is him going back to the time of a great hero like Hercules and joining forces with him to complete a quest that was left unfinished. Or he could travel to the future to see what has become of the demigod world and then come back to the present to try and prevent a bad future from happening.
Well, a cool plot could be that the Fates are actually trying to create a super - powerful alliance through Percy's harem. Each member of the harem could bring a special ability or power to the table. For instance, one might be a seer who can predict the future accurately, which would be very useful for Percy's quests. And Percy has to figure out how to manage all these relationships while also fulfilling his duties as a demigod.
Well, perhaps a plot where the harem members are from different camps in the Percy Jackson universe, like some from Camp Half - Blood and some from Camp Jupiter. Percy has to navigate the differences between them and also deal with the jealousy and rivalries that might arise. And they all have to work together to stop a powerful ancient evil that is targeting them specifically because of their unique group dynamic.
Well, a cool plot might be that Percy is on a quest that takes him through different dimensions. In each dimension, he encounters a powerful female character who decides to join him on his journey, gradually forming a harem. For instance, he could meet a female samurai from a Japanese - inspired dimension. Or perhaps there's a plot where an ancient artifact in the Percy Jackson world has the power to attract female heroes from across various universes, and Percy has to deal with all of them while trying to figure out what to do with the artifact.
One interesting plot idea could be Percy traveling back in time to the era when the gods first came to power. He could witness the creation of the Olympian council and get involved in the early power struggles among the gods. Another idea is that a god sends Percy on a time - travel mission to fix a mistake in the past that is now threatening the present world of demigods. For example, if a powerful magical artifact was lost in the past and its absence is causing chaos in the present.
A plot could involve Percy and his friends getting separated during a vapor travel accident. Each of them has to find their own way back while dealing with various challenges specific to the places they end up in. For example, Annabeth might find herself in a library - like realm where knowledge is a weapon and she has to outwit a knowledge - stealing creature. Percy could end up in a water - based vapor world where the laws of physics are different and he has to adapt quickly to survive.
A possible plot is that in a mass harem fanfiction of Naruto and Percy Jackson, there is a competition among the harem members to gain the attention and affection of Naruto and Percy. This leads to some chaos and jealousy at first. However, Naruto and Percy work together to create a harmonious environment. They introduce their own cultures and values to the harem. Naruto shares the concept of ninja honor and Percy talks about Greek mythology and the importance of loyalty. As they do this, they also face external threats that require them to unite the harem and fight together.
One idea could be Percy having to protect his harem from a new and powerful monster threat that specifically targets them because of their connection to him. Another could be Percy exploring his relationships within the harem while also dealing with his identity as the son of Poseidon in a world full of monsters.
One idea could be that Naruto, while on a strange mission, gets transported to the Percy Jackson universe. In this new world, he catches the attention of various female characters. Maybe he uses his ninja skills to help out at Camp Half - Blood, and the girls there, like Annabeth, are intrigued by his different abilities. They start to form a bond, and a harem - like situation begins to develop as Naruto tries to find his way back to his own world.
One idea could be Percy having to team up with the Hunters of Artemis on a quest. During this quest, he gradually earns the respect and friendship of the hunters, leading to some unique interactions within the harem - like - situation. Maybe they encounter a new mythical creature that only Percy can communicate with due to his Poseidon heritage, and this ability helps the group survive and brings them closer.
