I'm not sure who Ariel is in this context without more information. It could be a unique character created specifically for this 'never - ending story' that has its own set of characteristics and a role within the plot.
Ariel could be any character created by the fanfic author. It might be a mermaid, as the name Ariel is often associated with mermaids in popular culture.
There could be a male Ariel fanfiction where he teams up with other Disney male characters from different stories. For example, he could go on a quest with Aladdin to find a magical item that can save both their kingdoms. This would combine the elements of two different Disney universes and create an interesting story line.
In the original story, the mermaid's ending is tragic as she turns into sea foam, while in the Disney version, Ariel gets a happy ending and marries the prince. Also, in the original, she is mute on land due to the deal with the sea witch, but in Disney's, she regains her voice. The original mermaid is more about self - sacrifice and unrequited love, while the Disney one is more of a fairytale romance.
You could write a fanfic about Ariel's adventures in the human world after she becomes human permanently. She could be exploring new cultures, making new friends, and learning about human history and art. This would focus on her growth and discovery in a new environment.
One common theme could be redemption. Maybe the male Ursula has a change of heart. Another could be adventure, as they go on some sort of journey together.
There could be. Fanfiction writers are known for their creativity and coming up with all sorts of pairings. However, not all fanfiction platforms may have a large number of works for this specific pairing. You may need to dig a bit deeper. Look for tags related to both characters and also keep an eye out for any crossovers or alternate universe stories that might feature this pairing.
First, you need to think about the character of male Ariel. Decide on his personality traits, like whether he's brave, curious, or shy. Then, come up with a plot. It could be something as simple as his day - to - day life in the ocean or a grand adventure.
