Ariel is quite adventurous. Her sisters may be more nurturing. They could be the ones who take care of the younger sea creatures and are more concerned with the well - being of the ocean community as a whole. They might not be as eager to break the rules as Ariel was to go to the surface. Instead, they would rather maintain the harmony within their own underwater society.
One possible storyline could be that Ariel's sisters discover a hidden underwater kingdom that was lost long ago. They embark on a journey to explore it and learn about its history and secrets.
She could be more assertive in a rather dark way. Ursula is a very dominant character. Ariel, growing up under her influence, might not be as gentle as in the original story. For example, when it comes to getting what she wants, she might use more forceful or underhanded methods, rather than her pure - hearted charm in the original.
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.
If 'Ariel' is a real person, without more context, it's hard to tell their real story. It could be that Ariel has a story related to their personal growth, like achieving a dream in a difficult situation. Maybe Ariel overcame obstacles in their career or relationships, which would be parts of their'real story'.
