One of the main themes is loss. With Lily leaving James, there's a sense of something being broken in Harry's family. It's about how Harry deals with that void in his life.
One popular 'harry lily leaves james fanfiction' is 'The Unspoken Bond'. It delves into the complex relationships between the characters. It shows how Harry copes with the absence of his parents in a very unique way, with a focus on his connection to Lily's memories.
One great Hermione, James Potter and Lily Potter fanfiction is 'The Unlikely Trio'. It explores a unique alternate universe where Hermione time - travels and gets involved in the lives of James and Lily. The story is full of interesting character interactions and a well - crafted plot that keeps you hooked from start to finish.
One great fanfiction could be 'Lily and James: A Love Beyond'. It delves deep into their relationship before Harry was born. It shows how they met at Hogwarts, their initial dislike which gradually turned into love. The story also includes their adventures as members of the Order of the Phoenix and how they fought against the Dark forces side by side.
One possible fanfiction could focus on the moments leading up to their death. It might show James trying to protect Lily and Harry until the very last moment. He could be shown using his wand to fend off Voldemort as long as he could, while Lily was huddled in a corner with baby Harry, praying for a miracle.
Well, it could lead to a very different story. Harry's childhood and upbringing would be completely changed, and the dynamics of the wizarding world might shift.
Harry would often be a main character in these fanfictions. Since it's about bashing his parents, his reaction and how he copes with the new view of them is a big part of the story. Another could be Sirius Black. He was very close to James, so fanfictions might explore his feelings towards the bashing of his best friend.
The plot is key. It could be something like a time - travel plot where Hermione goes back in time and meets James and Lily. Or it could be a more complex plot where their magical abilities interact in unexpected ways. A great fanfic also has good pacing. It doesn't rush through the relationships and interactions between the characters. It takes the time to build up the tension, whether it's a friendship or a more romantic tension.
Petunia could be an important character. She might be grudgingly attending the wedding, still having mixed feelings about Lily's magical world. Her presence could add some tension as she struggles to fit in. And then there's Dumbledore. He could make an appearance and give some wise words of advice to the couple, perhaps about the future challenges they might face together.
Love is a very common theme. Their deep, passionate love for each other is often explored. Another theme is sacrifice, as we know from the original story that they sacrificed themselves for their son. Also, the theme of family, how they were building a family together before their untimely deaths.
