Well, 'Harry Potter and the Lost Relics' could be an exciting lost fanfiction. This could involve Harry and his friends on a quest to find powerful relics that have been lost for centuries. It would likely take them on adventures all over the wizarding world, from the Forbidden Forest to the depths of Gringotts. There could also be a fanfiction about 'The Lost Friendship in Harry Potter'. It might explore a scenario where a key friendship in the series is broken or lost and how the characters deal with the consequences.
Some fanfictions in this theme might focus on a lost child from a different wizarding family. For example, a child who was lost during a dark wizard attack on their family. The story could then be about how they find their way back to the wizarding world, specifically Hogwarts. They might have to overcome many obstacles and prejudices along the way. In the process, they might form an unlikely alliance with some of the main characters from the original series.
One great 'Harry Potter Lost Girl' fanfiction could be 'The Lost Magic in Hogwarts'. It combines the magical elements of Harry Potter with the unique charm of Lost Girl. Another might be 'Finding the Lost in the Wizarding World' which has an interesting plot about a character who is lost between the two universes and has to find their way. There's also 'Lost Girl's Adventure in Hogwarts' that takes a character from Lost Girl and drops them into the Harry Potter world for some really fun and unexpected interactions.
Some 'Harry Potter Lost Far Away' fanfictions focus on Harry being lost in a parallel magical world that has different rules. In this world, magic is more chaotic or perhaps more limited. Harry has to adapt quickly and find allies among the strange wizards and witches there. This type of story often delves into themes of self - discovery and the true nature of magic.
There's also a fanfiction where the lost baby Malfoy is found by Harry Potter himself. This could lead to a very different dynamic in their relationship. Harry, being the hero he is, might try to protect the baby from the dark forces that could be after the Malfoy family. It could show a side of Harry that we haven't seen before, a more nurturing side.
A really cool 'Harry Potter Lost Magic' fanfiction could involve the idea that there are lost magical creatures that hold the key to this lost magic. Harry and his friends go on an adventure to find these creatures. Along the way, they face many challenges and learn that the lost magic is not just about powerful spells but also about a different way of understanding and interacting with the magical world. For example, they might find a creature that can manipulate time, and the lost magic associated with it allows them to fix some of the past tragedies in the wizarding world.
Another great one is 'A Future for Harry and Ginny'. It imagines their life after Hogwarts, with how they deal with the wizarding world post - Voldemort. It's a heartwarming story that many fans enjoy.
I'd recommend 'A Black's Destiny'. It focuses on an OC Black who discovers a long - hidden family secret. This fanfiction is full of mystery and adventure, and it does a great job of staying true to the lore of the Harry Potter universe while introducing new and exciting elements through the OC.
One great fanfiction could be 'The Marauders' Library Adventure'. In this fic, the Marauders discover a hidden section in the Hogwarts library that has books with secrets about the wizarding world's past. It's really engaging as it shows their curiosity and how they react to the new knowledge.
One good one is 'The Wizarding World of Shinobi'. It combines the magic of Harry Potter with the ninja skills of Naruto in an interesting way. Another is 'Naruto at Hogwarts' which imagines Naruto as a student at Hogwarts and how he'd interact with the magical world. 'Potter and the Uzumaki' is also great, as it weaves a complex story that involves both universes and their unique elements.
One great Harry Potter fanfiction is 'The Life and Times' by Jewels5. It delves deep into Lily Potter's life at Hogwarts and her relationship with Severus Snape. It offers a new perspective on the events that led to the Potter family's fate. Another good one is 'Manacled' which has a very interesting take on the post - war wizarding world and Hermione's journey in it. There's also 'After the Battle' which focuses on how the characters heal and move forward after the final battle against Voldemort.
