One possible plot could be that Pikachu, the most iconic Pokemon, gets transported to the Pride Lands. There, he befriends Simba. Pikachu uses his electric powers to help Simba fight off the hyenas when they try to take over the Pride Lands again. Together, they show that friendship between different species can be very powerful.
Well, perhaps in this fanfiction, the Pokeballs could be like the baobab fruits in the Lion King world. A trainer, who is also a bit like a lion in spirit, arrives in the Pride Lands. He has Pokemon like Charizard, which is seen as a powerful and majestic creature similar to a lion. Charizard helps to protect the Pride Lands from a new threat, and in the process, the Pokemon and the lions learn from each other about loyalty and courage.
One idea could be that Tarzan, while exploring the jungle, discovers a strange new area that leads him to the Pride Lands. There, he meets Simba and the pride. Tarzan's unique jungle skills could help Simba in some way, like teaching the lions new ways to move through the trees to escape danger. And in return, Simba could introduce Tarzan to the ways of the lions and their social structure.
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.
A possible plot could be a Pokemon trainer getting lost and ending up in the Pride Lands. He has to use his Pokemon to survive and also make friends with the Lion King characters.
Perhaps there's a magical event that brings Tarzan and the Lion King world together. A mysterious force could transport Tarzan to the Lion King's world. He would be a strange sight for the Pride Lands animals. Tarzan could bond with young Simba or Nala. They could go on adventures together, exploring new parts of the Pride Lands. Tarzan might also introduce some of his jungle friends like the elephants or monkeys to the Pride Lands, creating a unique cultural exchange between the two very different ecosystems.
Well, perhaps in this fanfiction, there could be a common enemy for both Balto and the Lion King characters. Let's say an evil group of hyenas from Balto's world team up with Scar's old followers. Balto and Simba would then have to work together, combining their leadership and survival skills. Balto's experience with the wilderness and Simba's knowledge of the Pride Lands would be a great combination to defeat this new threat.
Start with a strong inciting incident. For example, a magical portal opens and transports a group of ponies to the Pride Lands. This immediately creates a situation full of potential conflict and discovery.
Well, perhaps a human is magically transported into the Lion King world. This human has a special connection with the stars, and they discover that an ancient evil is about to return. With the help of the Lion King characters, especially Rafiki who believes in the human's unique gift, they work towards preventing the disaster. The human could also introduce new concepts like music styles from our world to the animals in the Pride Lands.
Well, perhaps a plot where Scar had a secret love before his death. A lioness who was once in love with him now has to deal with his death and the new rule of Simba. She starts causing trouble in the pride, believing Simba is responsible for Scar's downfall, and this could lead to a lot of drama and action in the fanfiction.
One idea could be exploring what would happen if Simba had a long - lost sibling. Another could be a story where Scar had a change of heart before his final battle with Simba. Maybe a fanfiction about the animals in the Pride Lands having to deal with a new, unknown threat that even Mufasa didn't foresee.
