Harry Potter and Simba would likely be main characters. Harry with his magic skills and Simba with his leadership in the Pride Lands could team up for some great adventures.
Well, in a Harry Potter and Lion King crossover fanfiction, we might see Hermione being fascinated by the animal kingdom's natural laws which she compares to the laws of magic. She could try to teach the young lions about potions using local herbs. And Ron would probably be a bit scared of the big cats at first but then warm up to them.
Definitely Simba and Pikachu. Simba as the rightful king of the Pride Lands represents leadership and courage. Pikachu, being one of the most popular Pokemon, is full of energy and has a strong sense of loyalty. They could form an unlikely but strong friendship in the crossover.
The main characters would be Naruto, Simba, and Mufasa. Naruto enters the Lion King world and meets Simba. But through some magical or spiritual connection, he also gets to interact with Mufasa's spirit. Mufasa's wisdom combined with Naruto's skills and Simba's leadership would form the core of the story. They would face challenges together, like threats to the Pride Lands or internal power struggles within the animal kingdom.
Obviously, Harry Potter is likely to be one of the main characters. And the lion, whether it's a magical creature or has some other special significance, would also be a main character in this fanfiction.
In addition to the main trio from Harry Potter, Dumbledore could also be a major character. His wisdom and powerful magic could be crucial in dealing with Godzilla. He might be the one to come up with a plan to either communicate with Godzilla or find a way to send it back to its own world. On Godzilla's side, there could be some sort of a magical connection or entity that is controlling it or has a link to it, and that could also be considered a main character in the fanfiction.
The Hogwarts professors could also play important roles. Dumbledore could be seen as a wise old figure, much like Rafiki. He could offer guidance to the animals and the Harry Potter characters alike. Snape, on the other hand, might be a bit more difficult to place, but perhaps he could be a sort of protector in the shadows, using his potions knowledge to help heal any injured animals or deal with magical threats in the Pride Lands.
Definitely Harry Potter himself. He's the hero in the Harry Potter series, so he would be a central figure in the crossover. He could use his skills and courage to lead the way in the new, combined world. Ron and Hermione would also be important, as they are Harry's closest friends and would support him throughout the adventure.
The female characters like Nala and Tarzan could also have interesting interactions. Nala might be curious about Tarzan's way of life. She could ask him about the jungle, and Tarzan could be impressed by Nala's hunting skills. The other animals in the Pride Lands, such as Timon and Pumbaa, would probably be both scared and fascinated by Tarzan. They might make jokes about his strange appearance at first, but then grow to like him as he helps them with things like finding new sources of food or protecting them from danger.
Balto would probably be in awe of the large and majestic lions at first. The lions, especially Simba, might be curious about this strange wolf - like creature. They would likely communicate through body language and simple sounds at first, until they start to understand each other better.
In a 'lion king meets humans' fanfiction, Mufasa could still be a crucial character even though he is dead in the original story. His spirit could guide Simba in dealing with the new situation of meeting humans. As for the humans, it could be a family who got stranded in the Pride Lands. Each member of the family has different reactions to the lions, and this family dynamic along with their interactions with the lions could form the main plot of the fanfiction.
