There's 'Aurora of the Patronus'. It focuses on a group of young witches and wizards who, through their combined efforts and strong patronuses, fend off a dark force that threatens Hogwarts. The descriptions of the patronuses are vivid and make the story very exciting.

Well, 'Harry Potter and the Ascension of the Dark Lord' is an interesting one. It gives a different perspective on what could have happened if Voldemort had achieved his goals in a more complex way. Then there's 'Powerful Lords of Hogwarts' which features various characters attaining great power and the political and magical intrigue that follows. And 'The Potter's Dark Dominion' is a fanfic where Harry is sort of corrupted by power and the story unfolds from there, showing a very different side of the Harry Potter world.

One great 'Harry Potter powerful Auror' fanfiction is 'The Auror's Ascent'. It follows Harry as he quickly rises through the ranks of the Aurors, facing new and dangerous dark wizards. Another one is 'Auror Potter's Legacy' which shows how Harry uses his skills to train a new generation of Aurors. And 'Powerful Auror, Hidden Secrets' is also interesting as it delves into the secrets Harry discovers while on Auror missions.

There are quite a few 'oc raises Harry Potter' fanfictions. For example, in 'The Unconventional Upbringing', the oc is a time - traveling wizard from a different era. He decides to raise Harry Potter with knowledge from both the past and the future, which gives Harry a whole new perspective on magic. Then there's 'Raising Harry with Ancient Magic' where the oc is an expert in long - forgotten magical arts and uses this knowledge to raise Harry, making him a more well - rounded wizard compared to the books. 'The Oc's Guide to Raising Harry' is also a great one. Here, the oc is a very methodical and organized person who plans every aspect of Harry's upbringing, from his magical education to his social skills in the wizarding world.

Another great one could be 'A New Power in Hogwarts'. This fanfic features an overpowered OC who has a special gift related to magic that no one else in the story has. The OC's presence disrupts the normal hierarchy at Hogwarts and leads to many interesting plot twists as they interact with the likes of Harry, Hermione, and Ron.

There's 'A Mother's Magic'. In this fanfiction, the female OC is a powerful witch who discovers Harry early on. She decides to raise him away from the Dursleys. The story is interesting as it delves into how she teaches Harry things that Dumbledore might not have thought of, like a more practical approach to magic and dealing with the wizarding world politics from a young age.

One popular one could be 'The All - Powerful Potter' which delves into Harry having extraordinary powers and using them to reshape the wizarding world. It has a really engaging plot and well - developed characters.

Another one is 'Back to the Beginning'. This fanfiction delves deep into the idea of time travel being a powerful tool. The main character travels back in time and uses their knowledge of future events and spells to gain an upper hand. It also explores the moral implications of using time travel to change things, which adds an extra layer of depth to the story.

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.

Some powerful slash fanfictions in Harry Potter often focus on the unspoken tensions between characters. For example, fanfictions about Sirius and Remus can be really engaging. They may take the deep friendship from the books and add a romantic or more intense emotional aspect to it. These fanfictions can be powerful as they delve into the characters' psyches in ways the original books might not have fully explored.
