Perhaps a plotline where Naruto has to team up with his former enemies in order to face the common threat of the gods. This would involve complex character dynamics and growth as they put aside their differences. It could also lead to some really intense battle scenes where they combine their unique skills to take on god - like opponents.
One interesting plotline could be Naruto gaining new and extremely powerful abilities directly from the gods. For example, he might be able to control natural elements in ways that no one else can, like summoning a massive storm with a simple gesture. Another could be that the gods give him a special mission that takes him to new and mysterious lands within the Naruto universe, where he meets unique characters and discovers long - lost secrets.
One possible plotline could be Naruto gaining new powers that allow him to directly challenge the gods. For example, he might discover a hidden jutsu that gives him the ability to nullify divine powers. Another could be Naruto uniting the ninja world against a common threat from the gods, leading to epic battles and alliances.
One possible plotline could be Naruto and Hinata using their newfound god - like powers to protect the Hidden Leaf from a powerful, otherworldly threat. They could travel to different dimensions to gather allies or resources. Another could be them having to deal with the moral implications of being gods, like how much they should interfere in the lives of mortals.
Another plotline could be Naruto's journey to the Shinto realm. There, he could learn about his parents' past, the history of the Shinto gods, and gain new powers that he then brings back to the ninja world to make it a better place.
One possible plotline could be Percy challenging the gods' unfair rules. For example, he might snap at them for always using demigods as pawns in their games. Another could be Percy standing up for the rights of other minor demigods who are often overlooked by the gods. Maybe he decides to form a sort of demigod union to negotiate with the gods for better treatment.
One interesting plotline could be Harry leading a secret resistance against Umbridge within Hogwarts. He might use his skills in the DA (Dumbledore's Army) to outwit her at every turn. For example, they could use magic in clever ways to undermine her rules without getting caught.
Another plotline might involve a magical accident. For example, a spell goes wrong during a Defense Against the Dark Arts class and Snape and Hermione are caught in its effects. They end up in a situation where they are physically close and 'rubbing up against' each other in a strange magical way. This could force them to work together to reverse the spell, leading to character development and an unexpected bond.
Perhaps there's a plot where Harry has a vision of a future where the Order causes great harm. This vision is planted by an enemy of the Order. As a result, Harry decides to take pre - emptive action against the Order. He gathers his own group of allies who believe in his cause and they engage in a series of battles against the Order, with many twists and turns as the truth slowly unfolds.
A third plotline could be Percy being raised by the gods in a different era. He might be sent back in time to the age of the Titans and have to grow up among them while still retaining his loyalty to the Olympians. This would create a lot of internal conflict for Percy as he tries to figure out how to survive and still uphold his values.
One interesting plotline could be the mystery behind the mask. Maybe it has some special power that only Naruto can unlock or it could be related to an ancient prophecy. Another could be a new villain who uses the mask to create chaos in the ninja world and Naruto has to stop him.
