A cool plot could be a time - travel fanfiction. The Minotaur travels back in time to the era when the gods were more actively involved in the mortal world. He could interact with the gods, and Percy has to follow him through time to stop him from causing chaos. This would involve Percy having to deal with different rules and powers in the past, and also understanding the Minotaur's motives for going back in time.
In some fanfics, the Minotaur is a time - traveler, like in 'The Time - Traveling Minotaur'. It travels through different eras, and Percy has to follow it to stop it from changing history in a bad way. This plot is full of adventure and mystery. Another plot is 'Minotaur's Redemption Arc' which focuses on the Minotaur's journey to redeem itself. It shows how it tries to atone for its past actions and how Percy is involved in that process. 'The Minotaur's Hidden Power' is also a great plot. In this fanfic, the Minotaur has a hidden power that Percy discovers, and they have to figure out how to use it to save the world.
One interesting plot twist could be that the Minotaur is actually a misunderstood creature under a curse. In some fanfictions, it might be revealed that he was once a heroic figure before being transformed. Another twist could be Percy having a secret power that he discovers while fighting the Minotaur that changes the whole dynamic of their encounter. For example, he might be able to communicate with the Minotaur's mind and find out its true motives.
One idea could be that Percy, after his encounter with the Minotaur, discovers a lemon tree in the Camp Half - Blood that has some magical properties related to the Minotaur. Maybe the lemons can be used to create a potion that can temporarily weaken the Minotaur's strength. Another plot could involve a lemon - themed quest where Percy has to retrieve a golden lemon that the Minotaur is guarding. It could be a symbol of power that the gods want to keep away from the monsters.
Well, in fanfic, one interesting aspect could be different interpretations of Percy's encounter with the Minotaur. Maybe the fanfic writer gives Percy some new powers or abilities during the fight. Another aspect could be the expansion of the Minotaur's character, like exploring its backstory or motives more deeply.
Many fanfictions play with the idea of the Minotaur's appearance. While it always has the basic bull - head and human - body form, some might give it unique features like glowing red eyes that can hypnotize its victims. Or it could have a coat of fur that is described as being as tough as armor. The Minotaur can also be a catalyst for character development in fanfiction. For instance, when a young demigod first faces the Minotaur, it can be a life - changing moment that makes them grow stronger and more confident in their abilities.
One interesting plot could be Percy having to face an alternate version of himself that has turned evil due to some dark magic. This would create a great internal conflict as he battles not only an external foe but also his own dark side.
One interesting plot could be Percy and his friends going on a quest in a new, unknown realm. Maybe a place that's not part of the regular Greek mythology but still related in some way.
Another plot might be a scenario where Percy tries to reason with Kronos. He could attempt to understand Kronos' motives for wanting to destroy the Olympians and find a compromise. This would be a complex and emotional journey as Percy has to face the being who nearly destroyed his world.
One interesting plot could be where the NPU (assuming it's some new power or entity in the Percy Jackson universe) is a key to unlocking an ancient prophecy that no one knew existed. Percy and his friends have to figure out how to use the NPU to their advantage while also dealing with the usual monsters and gods trying to stop them.
One interesting plot could be Percy having to deal with new mythological threats while trying to balance his college studies. For example, a group of rogue satyrs causing chaos on campus. Another plot might involve Percy and his friends forming a secret society in college to protect the mortal world from hidden magical dangers. And sometimes, there are plots where Percy has a love interest who is also involved in the world of Greek mythology and they face challenges together in the college setting.
