Hermione Granger is a great character to include. Her intelligence and love for knowledge can interact in interesting ways with an SI or OC. Harry Potter himself, of course, as he is the central figure in the original series. And Draco Malfoy, his complex personality and family background can create a lot of drama when paired with an SI or OC. For example, an SI who tries to befriend Draco and change his views towards Muggle - borns.
Another good one could be 'A Cadmean Victory'. This fanfiction stands out for its complex character development. The self - inserted character has to navigate the tricky world of Hogwarts and the wider wizarding world, and the story does a great job of showing that journey.
For my Harry Potter mermaid OC fanfiction. There is a mermaid OC named Marina. Marina is a half - mermaid, half - witch. Her mother was a mermaid and her father was a wizard who disappeared long ago. She has been living in the lake near Hogwarts all her life. One time, when the Triwizard Tournament was taking place, and the second task involved the lake. Marina noticed the chaos. She decided to help Harry Potter find his way in the lake as she could sense his good heart. She guided him to his goal, using her mermaid powers and knowledge of the lake's secrets. After that, Harry was very grateful and often visited the lake to talk to Marina.
First, you need a unique and interesting character concept for your OC. Think about their background, personality, and magical abilities. Then, fit them into the world of Harry Potter while respecting the existing lore and characters.
I really like 'A New Beginning in Hogwarts'. The male OC in this fic is from a different magical culture, and when he arrives at Hogwarts, he brings in fresh perspectives. The story is full of adventure as he tries to adapt to the Hogwarts way of life while also hiding his own secrets.

One great 'fem Harry Potter and oc fanfiction' is 'The Girl Who Lived'. It offers a fresh take on the Harry Potter universe with a female Harry. The story is engaging as it weaves new relationships and adventures for the main character. It also has well - developed original characters that interact interestingly with the existing Potterverse characters.
In the original story, Harry often felt alone in his battles. But with an OC as his brother, there would be a constant ally. The OC could have different relationships with the teachers too. Suppose the OC has a particular interest in potions like Snape. This could lead to a different kind of mentorship and perhaps change Snape's view of the Potter family. And when it comes to the final battles, the OC could bring in additional magical artifacts or allies that were not part of the original story, completely changing the way the fight against Voldemort unfolds.
One great Harry Potter x OC fanfiction is 'The Black Family Heir'. It has an interesting original character who gets involved in the complex world of the Black family. The story is well - written, with great character development and it weaves the OC's story into the existing Harry Potter lore seamlessly.
