Harry Potter could obviously be one of the main characters. He has the experience of fighting against dark forces in his own world, so he would be a natural fit to take on the challenges in Middle - earth.
One interesting crossover could be the magic systems. In 'Harry Potter', magic is more about spells and potions, while in 'The Rings of Power' it's more about the power of the rings and ancient lore. A crossover might explore how a Hogwarts student would react to the One Ring's allure.
From the Power Pack, the four siblings would be key characters. Their different powers, like flight, super strength, invisibility, and energy projection, could bring new elements to the story. For example, Jack's leadership among the Power Pack could lead to some interesting power struggles or cooperation with Harry. And Kitty's ability to become invisible might be used in some sneaky missions in the wizarding world.
In a Harry Potter - Power Rangers crossover fanfiction, the main characters could be Ron Weasley from Harry Potter and the Pink Ranger from Power Rangers. Ron could provide some comic relief as well as his loyalty and friendship skills. The Pink Ranger could bring her unique combat style and femininity to the story. And of course, Dumbledore could play a major role too. His wisdom and power would be a great asset in dealing with the combined threats from both universes.
Well, it's hard to say for sure without reading it, but likely Harry Potter would still be a central figure. He might be in a more mature and powerful role, perhaps having to face even greater threats to the wizarding world.
It's hard to say for sure without reading it, but it could be Harry Potter himself. He often finds himself in the middle of things and might be involved in establishing or dealing with the power of order. Hermione could also be a main character as she is intelligent and would likely play a role in any new system of order. Ron might be there too, providing his loyalty and courage.
In many fanfictions, there are often original characters created by the author. In 'harry potter and the power of beast fanfiction', there could be a young wizard or witch who has a hidden connection to the power of the beast. They might be the key to unlocking the secrets of the beast's power. But of course, Harry Potter and his friends would likely be involved in some capacity, perhaps as mentors or allies to this new character, depending on how the story is crafted.
I don't know for sure since I haven't read this particular fanfiction, but it could be Harry Potter himself, or perhaps a new character that the author has introduced to have these god - like powers.
Hermione Granger could also be a main character. Her intelligence and knowledge of magic could play a crucial role in the story, especially when it comes to understanding the motives and powers of the Guardians of Power. And Ron Weasley might be there too, providing his loyalty and his own brand of magic skills.
Hermione could be there. She would be really helpful in planning and organizing the island. For example, she might set up a system for categorizing all the magical knowledge and resources on the island.
In this fanfiction, Harry Potter is the main character with the Triforce of Power. However, we can't forget about the Hogwarts professors. They could play crucial roles in helping Harry understand the implications of this power. Neville Longbottom might also have a part to play, perhaps as a support to Harry or someone who is also affected by the presence of this new power in the wizarding world. And of course, the Death Eaters would be important antagonists as they would either be after Harry's new power or be threatened by it.
