One interesting fanfiction could be about Percy Jackson's adventures that are more closely tied to his relation as Zeus's grandson. Maybe he discovers some hidden powers that are passed down only through the Zeus lineage. He could face challenges where his Zeus - related powers are both a blessing and a curse, like when he has to control excessive lightning powers during a battle with a powerful monster.
Well, the plot could be centered around Percy's attempts to bridge the gap between his father Poseidon and his grandfather Zeus. There have always been tensions between the two gods. Percy, using his unique position, tries to bring peace. But there are forces at work, like some rogue demigods who don't want peace between the two powerful gods. They try to sabotage Percy's efforts, leading to a series of adventures and challenges for Percy.
In this kind of fanfiction, Percy might challenge Zeus over issues like the unfair treatment of demigods. For example, Zeus could be overly harsh on demigods who make minor mistakes while the gods themselves get away with much worse. Percy, being a hero, would stand up for his fellow demigods.
Another possibility is that Percy discovers some long - forgotten weakness of Zeus. In the world of fanfiction, the author could create a scenario where Percy stumbles upon an ancient prophecy or a hidden secret about Zeus. This knowledge could give Percy the upper hand. He could then use his wits and his powers to exploit this weakness and defeat Zeus.
One great fanfiction idea could be a story where Zeus, Poseidon and Hades have to team up to face a common threat that is even more powerful than them. Maybe a primordial being awakens and they must put aside their differences. In this story, Percy could be the mediator between them, using his unique position as the son of Poseidon to try and keep the peace among the three powerful gods.
This could be a really interesting fanfiction idea. Percy Jackson has his own rich world of Greek mythology in the 'Percy Jackson' series, and Dumbledore is from the 'Harry Potter' universe. Combining them could lead to some unique magic and adventure. Maybe Percy would inherit some of Dumbledore's wisdom and magical abilities along with his own demigod powers. It could be set in a world where the two fictional universes collide, and Percy has to use both his skills to face new threats.
One idea could be Percy having to mediate between Zeus and Hades during a major feud. Since he's the son of both in this fanfiction, he has a unique connection to them. He could use his powers and his knowledge of both of their domains to try and broker peace.
For the demigods, things could change a lot too. Percy is a champion of the demigods, and his victory over Zeus might mean better treatment for demigods. They could be more respected and have more rights in the world of gods and mortals. However, it could also make them targets of those who are against Percy's actions.
In some fanfictions, Zeus interacts with Percy in a hostile way at first. He sees Percy as a threat to his power and the order of Olympus. For example, he might try to limit Percy's abilities or send challenges to prove Percy's unworthiness.
Well, at first, they might be cautious around each other. Percy is used to being the main hero, and the daughter of Zeus's sudden appearance could make him a bit jealous or at least wary. But as they face challenges together, they start to respect each other. Maybe she saves Percy from a difficult situation, and he realizes she's not just there to steal his thunder. Over time, they could become good friends, relying on each other's unique skills in battles against monsters.
One possible plot could be that the entire Greek pantheon is thrown into chaos. Percy might be seen as a huge threat, and other gods and goddesses would either try to hunt him down or form alliances with him out of fear or a desire for power. Demigods would be forced to take sides, leading to massive battles among them.
