Maybe a fan fiction where the Little Prince meets other characters from different children's books. For example, he could encounter Alice from 'Alice in Wonderland' and they have an adventure together, comparing their strange and wonderful experiences.

A different plot could focus on the relationship between the Nutcracker Prince and the other toys in the land. There could be some sort of internal conflict among them, and the Nutcracker Prince has to use his leadership skills to resolve it.

There could be a plot where the sea creatures in Ariel's world start to lose their magic due to some dark force.

Perhaps in a fan fiction, a powerful sorcerer kidnaps both Prince Eric and Aladdin. Trapped together, they have to use their unique skills to escape.

They become friends during this ordeal and learn from each other.
Well, a plot could be that Prince Charming and Snow White are actually from two different kingdoms that are at war. They meet and fall in love in secret. They then try to find a way to end the war between their kingdoms so they can be together.

Prince Charming has to find a way to break both curses.
One idea could be that Ariel and Eric go on a magical underwater adventure together.

Well, you could write a fan fic where the relationships between the characters are reversed. So if in the original there are certain rivalries, in the fan fic they become allies and vice versa. Also, a story about a character who loses their power but discovers a new way to be strong within the 'unordinary' world would be interesting. Or how about a fan fic that takes place in a parallel dimension within the 'unordinary' universe where the rules of powers are slightly different?
