The magical creatures could play a role in helping Harry. For example, the centaurs with their deep understanding of the stars and magic could offer their wisdom. The house - elves, like Dobby (if he's alive in the fanfic), might use their unique magic to assist Harry in a time of need.
One possible plot could be that Harry is facing a new and powerful dark wizard threat in the wizarding world. He might need help from his friends, Hermione and Ron, to figure out the wizard's motives and weaknesses. Maybe he also needs the help of some long - forgotten spells or magical artifacts to defeat this enemy.
These fanfics are popular as they offer a different perspective on Harry's story. Harry always longed for a family and his mother's love. Fanfic writers can explore how that longing could be fulfilled, adding new layers to his character development. For example, a story where his mother's love gives him extra strength against Voldemort is both heartwarming and exciting.
Character development is key. The writer should show how Harry and Ginny grow both individually and as a couple. Harry might overcome some of his remaining trauma from the war, and Ginny could become more confident in her relationship with Harry. Also, the dialogue should feel natural. When they talk, it should be like how we expect them to talk in the Potter universe. It should capture their personalities well, with Harry being brave and a bit self - sacrificing, and Ginny being feisty and independent.
You should include some of the other characters as well. For instance, Hermione could be scolding Harry for not going before they left on their adventure. Ron could be making jokes about it. Also, don't forget to add some magic elements. Maybe Harry tries to use a spell to hold it in but it backfires in a funny way.
The exploration of their individual characters within the context of the relationship is also important. Harry's bravery and Fleur's allure are enhanced when they are together. The fanfic may show how Fleur's veela charm affects Harry in a new way, and how Harry's heroism makes Fleur see him in a different light. This character exploration helps to make their relationship more believable and engaging.
One popular 'harry needs to be with fleur fanfic' could be 'The Unforeseen Bond'. In this fanfic, the author weaves a story where Harry and Fleur's relationship develops in the aftermath of the Battle of Hogwarts. They start to discover shared interests and a mutual respect that slowly blossoms into a deeper connection.
A 'Harry Needs His Mom' fanfic might focus on an alternate universe where Harry's mother somehow survives. She then uses her magic and love to protect Harry from all the threats that come his way, and they have a very close mother - son relationship that changes the course of the wizarding world.
Perhaps Fleur is a key part of a prophecy related to Harry's life. In this fanfic, it could be that without her presence and active participation in Harry's life, he will die. For instance, she might be the one who can unlock a hidden power within Harry that is necessary for his continued existence. Like she has to be with him at certain times or places to trigger this power.
Voldemort could be the antagonist. He might find out that Harry needs Fleur to live and try to capture or kill Fleur to get at Harry. Since Harry is a threat to his power, eliminating the person Harry depends on for his life would be a strategic move for Voldemort.
