It could be a new student at Hogwarts. This student might come from a non - magical family but has a strong connection to magic that they didn't know about before. Their journey at Hogwarts would be their new beginning at life in the wizarding world.
Maybe a group of pure - blood supremacists who didn't like the changes that Harry brought to the wizarding world after the war. They believe that the old ways of pure - blood dominance should be restored and will stop at nothing to oppose Harry's new beginning, which includes more equality among all wizards and witches.
One possible plot could be that Harry discovers he has a long - lost relative who is a powerful wizard from a far - off land. This relative could introduce Harry to a whole new world of magic that he didn't know existed within the wizarding world. It could lead to new adventures, new spells, and new challenges for Harry to overcome.
Maybe it's a character who has been in the background in the original books but now gets their chance to shine. Like a house - elf who decides to break free from their servitude and start a new life. They could discover their own magical powers that were suppressed all this time and use them to create a whole new existence for themselves in the wizarding community.
A former Death Eater who has had a change of heart could be the main character. They are now trying to make amends and start a new life. Their past experiences would make them a complex and interesting character as they struggle to fit into the new, post - Voldemort wizarding society.
Well, it could be about a character getting a fresh start in the wizarding world. Maybe they've had a rough past and now they're starting anew. For example, it could be a student who was bullied but then finds a new group of friends and a new purpose in life at Hogwarts.
Perhaps a new student from a far - off land could be the main character. This student could bring new magical traditions and knowledge to Hogwarts, and have to deal with the cultural differences while also getting involved in some big adventure, like unravelling a mystery that threatens the entire wizarding community.
It could be a new dark wizard who has emerged in Harry's new life. This wizard might be jealous of Harry's fame and want to take him down.
Thor could be a main character. His godly powers and his somewhat otherworldly nature would add an interesting element to the story. And then there's Snape. His complex personality and his skills in potions and the dark arts could play a significant role, especially if there are plot elements related to poisons or dark magic that the Avengers need to deal with.
It might be a new transfer student from a far - off magical school. This student brings with them the knowledge or potential to be the new Merlin figure. They could have a different approach to magic compared to what's taught at Hogwarts, which makes them stand out as a possible Merlin - like character.
It could be an ordinary person from our world, like a high school student. They're suddenly thrust into this new world and have to adapt. Their inexperience in this new environment can lead to many humorous and exciting situations.
