Obviously, Harry Potter is one of the main characters. Since it's about him as the Sorcerer Supreme, he would be central to the story. Hermione and Ron would likely also be important characters, supporting Harry in his new role and adventures. They might help him research about the powers and responsibilities of the Sorcerer Supreme.
There could be new characters introduced as well. For instance, an old wizard who was once in line for the Sorcerer Supreme title but lost it. He could act as a mentor or a rival to Harry. And there might be characters from other magical cultures who come into play because of the broader scope of power that the Sorcerer Supreme has, like a powerful elf or a dragon rider.
Dumbledore could also be a significant character, even if he's no longer alive in the original series. His wisdom and past experiences could be revealed through memories or magical artifacts. His influence could guide Harry in his journey as the Sorcerer Supreme, especially when it comes to making difficult decisions about using power for good and protecting the wizarding world.
Obviously, Harry Potter would be one of the main characters as it's in the title. He would be in the role of the Sorcerer Supreme. Hermione and Ron would probably still be important characters, supporting Harry in his new role and adventures.
I think it has the potential to be good. It combines two very cool concepts - Harry Potter and the Sorcerer Supreme. However, the quality can vary a lot. Some fanfiction writers do an amazing job of weaving a new story within the existing Potterverse, while others might not be as skilled.
Yes, it can be quite popular. Combining the world of Harry Potter with the concept of the Sorcerer Supreme, which is often associated with Doctor Strange in the Marvel universe, creates an interesting crossover. Fans enjoy exploring how Harry Potter's magical abilities and world could interact with the idea of being the most powerful sorcerer, like the Sorcerer Supreme.
One possible plot could be that after the defeat of Voldemort, the magical world is in a state of flux. Harry, in his search for a way to further secure the safety of the wizarding world, stumbles upon the ancient power of the Sorcerer Supreme. He then embarks on a journey to master this power. Along the journey, he meets old friends who have different reactions to his new path, and he also uncovers a conspiracy within the wizarding world that wants to use his new power for their own dark purposes. As he grows in power, he has to make difficult choices about how to use it and who to trust.
Well, Harry Potter himself often appears in these fanfictions. He might befriend or be in conflict with an elemental sorcerer. Hermione is also common, perhaps she studies the theory behind elemental sorcery.
The plot might involve the Sorcerer Supreme realizing the great potential in Harry Potter. He could start by teaching Harry basic magical control in a very different way than normal. As Harry grows, he gets involved in the Sorcerer Supreme's battles against other magical threats. This gives Harry a broader perspective on magic. When he has to face Voldemort, he uses his unique training and knowledge to outwit the Dark Lord in ways that no one expected.
One interesting plotline could be Harry Potter somehow inheriting the title of Sorcerer Supreme. Maybe he discovers ancient magic that links him to this powerful position and has to learn new spells and face new enemies. For example, he might have to deal with dark wizards who are after the power associated with the Sorcerer Supreme.
One common theme is power expansion. Harry is already a powerful wizard in the original series, but as the Sorcerer Supreme, his powers are enhanced and he has to learn to control them. Another theme could be cross - universe encounters, like meeting characters from the Marvel universe where the Sorcerer Supreme concept originates.
It could be a rogue wizard who wants to steal the power of the Grand Sorcerer. He might be jealous of the Grand Sorcerer's abilities and wants to use that power for his own dark purposes.
There could be a plot where Harry Potter as the Sorcerer Supreme has to interact with other powerful magical beings from different dimensions or realms. He might have to use his enhanced powers to protect the wizarding world from threats that come from outside their normal scope of knowledge. This could lead to all sorts of exciting adventures and challenges.
