Hermione Granger is likely to be a main character too. Her intelligence and knowledge of magic would play an important role in the fanfiction, especially if it focuses on problem - solving and exploration of magic. She could be Harry's partner in many adventures.
Obviously, Harry Potter is one of the main characters. He is the central figure around which the story revolves.
Ron Weasley may also be a main character. His loyalty and friendship to Harry are important aspects. He could provide comic relief at times and also be a crucial part of the group in battles and other challenges. And of course, depending on the plot, there could be other characters like Dumbledore or Snape also having significant roles in the fanfiction.
In 'hp the intelligent potter fanfiction', there could be stories where Harry is much more intelligent than in the original. He might outwit his enemies in more creative ways. He could use his knowledge of magic history and ancient spells to defeat Voldemort in a completely different manner, like finding a way to nullify the Dark Lord's Horcruxes without using the traditional methods.
Hermione is often depicted as one of the most intelligent. Her love for books and knowledge in the original series makes her a natural candidate to be highly intelligent in fanfiction as well.
Harry, as we all know, has his group of friends like Ron and Hermione in the original story. But in this fanfiction, Gabby becomes a central figure in his life. Gabby could be a character who is new to the wizarding world of Hogwarts or she could be someone with a mysterious past that Harry is drawn to uncover. Their relationship and the development of their characters are what drive the story forward.
The dark lord himself is obviously a main character. There may also be a young hero or heroine who stands against him.

Often in fanfiction, the main character in part one could be an ordinary person from one of the universes who is thrust into the other. So it could be a Hogwarts student who is not as well - known as Harry, but still has a thirst for adventure. They find themselves in the Pokemon world and have to quickly adapt. Or it could be a novice Pokemon trainer who stumbles upon a magical portal to Hogwarts and has to figure out how to survive in a world full of wizards and witches.
Alice is another popular character. Her ability to see the future can be really interesting when combined with Bella's intelligence. For instance, Bella could use Alice's visions to plan ahead and make more intelligent decisions. Also, Jacob might be included, especially if the fanfiction involves Bella using her intelligence to solve problems between the vampires and the werewolves.
I don't know for sure as I haven't read it. But it could be the children of the main characters from Sword Art Online's Aincrad arc and some well - known characters from the Harry Potter series.
It could be Harry, Ron and Hermione. They are the central characters in the Harry Potter series and are likely to be involved in such a fan - created scenario like a poker game.
