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.
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.
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.
It could be Orochimaru from Naruto who somehow finds his way into the Lion King world. He would be interested in the unique magic and power of the Pridelands. He could try to control the lions or use them for his evil experiments, like he did with his human subjects in Naruto.
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.
Obviously, Naruto and Moana would be the main characters. They are from their respective universes and would be the ones driving the story forward in a crossover. Their different personalities and abilities would create interesting interactions.
A Lion King Transformers crossover fanfiction would likely involve a lot of character interactions. The Transformers, being from a completely different universe, would have different values and ways of life. But they could find common ground with the animals in The Lion King. For instance, the Autobots' fight for peace could align with the lions' desire to protect their home. The Decepticons, on the other hand, might see the Pride Lands as a place to conquer for resources. This would set up a great conflict, with the lions and Autobots teaming up to fight against the Decepticons.
Since it's a Naruto - based fanfiction, Naruto himself is likely to be one of the main characters. There may also be some original Western - inspired characters created for this fanfic to interact with Naruto.
One interesting plot could be that Naruto is somehow transported to the Pride Lands. He could use his ninja skills to help Simba fight against Scar's remaining followers who are still causing trouble. Maybe Naruto teaches the lion cubs some basic ninja moves for self - defense.
