There's an original character called Aurora in some fanfictions. She's a pure - blood witch with a passion for ancient magic. She's constantly on a quest to discover long - lost spells and artifacts. Her relationships with the existing Harry Potter characters, like Hermione, are really engaging as they often team up to solve mysteries related to magic history.
A great original character in Harry Potter fanfiction is often one that blends well with the existing world. For example, if they have a backstory that ties in with Hogwarts or other wizarding locations. They should also have unique abilities or traits. Like a character who can see the magical auras of spells as they're being cast.
Well, it really depends on the story. However, Sirius Black often shows up in RAB fanfiction and can be a great character. He has his own connection to the Black family, which RAB is also part of. His loyalty and courage can make him stand out in these fan - created stories. For example, in some fics, he helps to uncover the truth about RAB, adding depth to the plot.
One that stands out is 'The Time - Turner's Daughter'. This fanfic has a very creative and original storyline where a character related to the Time - Turner device plays a major role. It's long and full of surprises. It also does a great job of maintaining the feel of the original Harry Potter books while bringing in fresh ideas.
I think Harry would be great as Tracer. Just like Tracer, Harry is quick - witted and has a sense of adventure. He could use his magic to enhance Tracer's already impressive speed and time - jumping abilities. Also, both are kind of scrappy heroes who don't give up easily.
In my opinion, Dumbledore would still be a great headmaster in fanfiction. His wisdom and experience are invaluable. He always had a deep understanding of the students and was able to guide them through difficult times. He also had a great sense of humor and was very approachable despite his great power.
One great Harry Potter OC fanfiction is 'The Changeling' which features an original character who has a unique backstory and interactions with the main cast. The character's journey through Hogwarts and their role in the wizarding world's events are really engaging.
One great Harry Potter OC fanfic is 'The Life and Lies of Albus Severus Potter' which gives a really interesting take on Albus' character and his relationships within Hogwarts. It has a well - developed OC who interacts with the canon characters in a believable way.
There's a character in some fanfictions called Lyra, a half - veela who has the power to control emotions. She becomes Harry's love interest and her powers often come in handy during battles. Another interesting one is Orion, a powerful wizard who was once a student at Hogwarts but was banished for trying to expose a dark secret within the school. He returns to help Harry in his fight against Voldemort.
In some OC fanfictions, it could be a new witch created by the author. For example, a shy witch who meets Harry in the Forbidden Forest while he's on one of his solitary walks. She might be secretly helping him with some of his struggles against the dark forces without him knowing at first, and gradually a romantic relationship develops.
It's hard to say who the 'best' are, but there are some well - known names in the fanfiction community. Some authors who have a large following often create really engaging storylines that stay true to the essence of the Potter universe while adding their own unique twists with Harry and Rose Potter.
