Another creative concept is that the Lion King characters are brought into the modern world of the Avengers. Simba is amazed by the tall buildings and technology. He teams up with Captain America to learn about leadership in this new world. Meanwhile, the other Lion King characters get into all sorts of comical situations. Nala might be intrigued by Black Widow's fighting skills and ask her for lessons. And the hyenas could cause chaos in the city until the Avengers and the Lion King crew work together to stop them. This would be a fun mix of two very different universes.
A really out - there fanfiction idea would be that the Lion King's Pride Lands are actually a hidden dimension within the Marvel universe. The Avengers discover this dimension when they are investigating a strange energy signal. Once there, they find that the Lion King characters have a special kind of magic that is connected to the Infinity Stones in some way. They have to work together to unlock the secrets of this magic and use it to defeat an enemy that is threatening both the Pride Lands and the regular Marvel universe. This would involve a lot of world - building and exploration in the fanfiction.
The idea of Pokemon having the same social structures as the animals in the Lion King is very creative. For instance, electric - type Pokemon might form a group like the hyenas, being mischievous but also having their own hierarchy. And the grass - type Pokemon could be like the antelopes, being peaceful but having to be on guard against the 'predator' - like Pokemon.
One idea could be that the ponies from MLP find themselves in the Pride Lands. Maybe Twilight Sparkle uses her magic to help solve a problem that the lions are facing, like a drought. She could use her knowledge of spells to bring rain.
Well, one creative idea is when the dinosaurs in 'Dinosaur King' have chakra, just like in 'Naruto'. So they can perform ninja - like abilities. It's really cool to imagine a T - Rex doing a fire - based jutsu.
One creative idea is the Avengers getting involved in the power struggle for the Iron Throne. Maybe they side with different houses based on their own moral compasses. Another is the use of superpowers in the battles of Westeros. For instance, Doctor Strange could use his magic to turn the tide of a battle like the Battle of the Bastards.
One great Avengers - Lion King fanfiction could be where the Avengers are somehow transported to the Pride Lands. Maybe Thor is mistaken for a strange new kind of lion with his long hair and powerful physique. They could team up with Simba and his friends to fight off a new threat that is endangering both the Pride Lands and Earth, like an alien force that wants to take over all the realms.
A very creative 'Naruto' fanfic idea could be a time - travel one. For example, Naruto travels back in time to prevent the Uchiha massacre. Another idea is a fanfic where the ninja world is merged with the fairy - tale world. So Naruto could be fighting against the Big Bad Wolf or teaming up with Cinderella. And a fanfic where the Sharingan has a completely different power, like the ability to control the weather, would also be a very creative concept.
A creative plot could be where the Black Order switches sides and helps the Avengers against an even greater threat. This would turn the typical dynamic on its head. The Avengers would have to trust their former enemies, and the Black Order would have to prove themselves.
A fanfiction could also be about the hyenas getting a second chance. Maybe they find a new place to live and try to form a more positive community, with some help from the lions.
Here's a plot. There is a magical realm where inflatable sheep are the guardians. An evil force from that realm escapes to Earth. The inflatable sheep follow to stop it, but they need the help of the Avengers. The Avengers are skeptical at first but soon realize the importance of the inflatable sheep. They team up and face various challenges together, like dealing with the evil force's minions who are trying to stop them from reaching the source of the evil.
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.
