Voldemort can still be a key character in these fanfictions. Smart Potter's intelligence might be the key to finally defeating Voldemort in a more strategic and less brute - force way. And Dumbledore may also play an important role, either as a guiding figure for Smart Potter or as someone whose actions are questioned by the smarter and more perceptive Smart Potter.
Obviously, Smart Potter is a main character. He is often depicted as a more cerebral version of Harry Potter. Hermione might also be a prominent character as she shares Smart Potter's love for knowledge and they could be study partners or rivals in these fanfictions.
Hermione Granger might also be a main character. Her intelligence would be very useful in a smart trial scenario. She could be using her vast knowledge of magic and books to help someone during the trial.
Obviously, Harry Potter would be one of the main characters since the title implies it's about him. There might also be his twin, though it's not clear from the original Potter series who that would be. And of course, his friends like Ron and Hermione would likely be part of the story too.
Hadrian is the central figure in most of these fanfictions. He is usually depicted as a more complex or altered version of Harry. Voldemort can also be a significant character, as the main antagonist in the Harry Potter universe. In some fanfictions, new characters are introduced who play important roles in Hadrian's life, such as a mysterious mentor or a rival wizard. Snape might also be there, his relationship with Hadrian being a key aspect in some stories.
Obviously, Harry Potter is the main character in these fanfictions. But often, his friends like Hermione Granger and Ron Weasley also play important roles.

There could be original characters created specifically for the fanfiction. These could be a group of wizard thieves who have their own motives and backstories.

One of them could be the leader, a charismatic wizard with a mysterious past.
Obviously, Haldir is one of the main characters. He brings his unique elven qualities from the Lord of the Rings realm into the Harry Potter universe. Harry Potter himself is often a main character as well, as the fanfictions usually involve some sort of interaction between him and Haldir. And then there are other Hogwarts characters like Hermione and Ron, who might be involved in the story, for example, they could be curious about Haldir and his strange ways.
Well, clearly Harry Potter and Acheron are main characters.

Hermione and Ron could also be important characters as they are Harry's closest friends and often get involved in his adventures in fanfictions too.
In some fanfictions, Smart Potter is not just book - smart but also socially smart. He uses his intelligence to understand the political undercurrents in the wizarding world.

One great 'Harry Potter' smart fanfiction is 'The Man Who Lived'. It offers a really interesting take on how Harry might have been different if he had grown up with a different set of circumstances.

Obviously, Harry Potter himself is the central character as 'Lord Potter'. Then there are his friends like Hermione and Ron. In some fanfictions, they play different roles.
