Well, a great plot in harry potter and phoenix fanfiction could be about the Marauders' Map falling into the wrong hands. This could lead to a whole new set of adventures and dangers for Harry and his friends. Also, fanfiction could explore the backstories of some of the minor characters in the Order of the Phoenix. What if one of them had a hidden connection to Voldemort's past? It would add a new layer of mystery and intrigue to the story.
In harry potter and phoenix fanfiction, a really cool idea could be if the phoenix Fawkes had a more direct role in helping Harry. Maybe Fawkes could communicate with Harry in some way and give him special insights or powers. Another interesting angle is to look at how the Ministry of Magic's interference in Hogwarts affected the students in ways that weren't shown in the original books. For instance, some students might have formed secret groups to oppose Umbridge in more extreme ways.
In a fanfiction, the Phoenix and the Basilisk could be two parts of an ancient prophecy. Harry Potter is the one foretold to either unite them or destroy one to save the other. Along the way, he has to learn about the true nature of both creatures. He might find that the Basilisk isn't as purely evil as it seems and the Phoenix has a more complex role than just being a symbol of good. This could lead to a very engaging story full of moral dilemmas and exciting magical encounters.
A plot could be where the Phoenix wand is stolen and Harry has to go on a quest to get it back. He might have to face dark wizards who want to use the power of the phoenix feather for evil. Along the way, he discovers more about the true nature of his wand and the connection it has to the wizarding world as a whole.
One interesting plot idea could be a crossover where the Phoenix Slayer magic is introduced into the Harry Potter world and a character has to learn this new form of magic to defeat a dark wizard. Maybe the Phoenix Slayer magic can control the power of phoenixes in a different way than what is known in the original Potterverse.
One interesting plot idea could be exploring the backstories of the minor characters in the Order more deeply. For example, what made them join the Order and their personal struggles during the fight against Voldemort.
In a fanfiction, the Ice Phoenix might be a transformed form of a loved one of Harry's, like his mother. It could be that in a moment of great danger, his mother's spirit took the form of an Ice Phoenix to protect him. This would add an emotional depth to the story as Harry tries to understand the connection and also use the Ice Phoenix's powers to fight against the forces of evil. The Ice Phoenix could also have the ability to freeze time for a short while, which Harry could use to his advantage during difficult battles or when he needs to make a quick escape.
Perhaps the phoenix can travel through time as well in this fanfic. Harry travels back in time with the phoenix to a crucial moment in the wizarding world's history. He has to make sure not to disrupt the timeline while also learning something that can help in his present fight against the dark forces.
Another plot point could be the origin of the Dark Phoenix in this fanfiction. It could be related to some ancient and dark magic that has been awakened. This might involve a search for the source of this power and a race against time to prevent it from spreading and causing chaos throughout the wizarding world.
A great plot for a Potter Manor fanfiction could involve a mystery that surrounds the manor. For instance, strange noises at night lead Harry to uncover a long - forgotten chamber. It could also be about Harry restoring the manor to its former glory, perhaps with the help of Hermione's research on ancient magic used in the construction of such manors.
One interesting plot idea could be exploring what would happen if Harry had a different upbringing, like being raised by the Malfoys. It would completely change his view of the wizarding world and his relationships. Another idea might be a time - travel fanfic where Harry goes back to the Marauders' era and interacts with his parents and their friends. This could lead to him preventing certain tragedies or changing the future in unexpected ways. And then there's the concept of a fanfic where the roles are reversed, and Voldemort is the one trying to protect the wizarding world from a greater evil, with Harry being the main antagonist.
One idea could be that the Hulk somehow gets transported to the wizarding world. He might be initially seen as a dangerous creature, but then the Hogwarts students discover his good side and he helps them fight against a new dark wizard. For example, his super strength could be used to break through dark magic barriers.
