One idea could be a crossover where Rapunzel from Tangled ends up in the underwater world of The Little Mermaid. Maybe she uses her long hair to help Ariel in some way, like rescuing her from a sunken ship. Another idea is that Flynn Rider and Prince Eric meet and have to work together to save both their princesses from an evil sea witch who has joined forces with a land - based villain.
First, think about the characters. Decide how Rapunzel and Ariel will interact. Will they be friends? Rivals? Then, choose a setting. It could be a new place that combines elements of Corona and Atlantica, like a beach near Corona with underwater caves leading to Atlantica. After that, come up with a plot. Maybe there's a common enemy, like an evil wizard who wants to steal Rapunzel's hair and Ariel's voice.
One idea could be that Rapunzel's long hair has some sort of magical connection to the underwater world of the Little Mermaid. Maybe her hair can be used to communicate with the mermaids or even has the power to purify the polluted parts of the ocean.
In Tangled and Little Mermaid fanfiction, Pascal, Rapunzel's chameleon, can be a really fun character to include. He could have some really interesting interactions with Flounder or Sebastian from The Little Mermaid. Maximus, the horse from Tangled, could also be a great addition. And of course, Ursula from The Little Mermaid is a popular villain to feature. Writers can create new scenarios where the heroes from Tangled have to face off against her.
One interesting Tangled and The Little Mermaid fanfiction could be about Rapunzel and Ariel meeting. Maybe Rapunzel's long hair gets tangled in Ariel's underwater world. It could be a story of them helping each other out of difficult situations and learning about each other's very different worlds.
I think Flynn Rider would be really interesting. Imagine him in the underwater world of the Little Mermaid. His charm and roguish ways would be a contrast to the more innocent mermaids. He could probably teach Ariel a thing or two about being a bit more street - smart while also being charmed by her naivete.
Ursula as a mermaid in fanfiction might also explore her backstory more deeply. She could have been a mermaid princess in a far - off part of the ocean. But due to a power struggle or a curse, she lost her status and became the villain we know. This could add a lot of depth to her character and make the fanfiction really engaging.
Tarzan is my favorite. I love the idea of a human being raised by animals in the jungle. The relationship between Tarzan and his ape family is very interesting. Also, the animation of the jungle scenery is amazing. It makes you feel like you are really in that wild and exciting environment.
Similarities include having memorable characters. Elsa from Frozen, Ariel from The Little Mermaid, Tarzan, and Rapunzel from Tangled are all well - known. They also have elements of love in their stories. In Frozen, it's the love between sisters. In The Little Mermaid, it's Ariel's love for Prince Eric. However, their story structures are different. Frozen has a more complex plot with multiple sub - plots about the kingdom and Elsa's powers. Tarzan's story is more about his adaptation to human society after being raised by apes.
