One popular element could be the unique mermaid lore. Mermaids often have their own underwater kingdoms, so in this fanfiction, it might explore the politics and society within that underwater world. Another element could be the relationship between mal and other characters. Maybe there's a special bond with a human who discovers her mermaid secret.
Maybe a human fisherman who is over - fishing and endangering the mermaid's home. He doesn't care about the underwater world and Mal has to stop him to protect her friends and family. So he becomes the main antagonist.
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.
Mal might meet a group of outcasts like herself. They are all running from different problems but have formed a kind of family. Together, they teach Mal the importance of community and support, and they all help each other face the challenges that come their way.
A fanfiction might explore how Harry and Mal's relationship evolves after the events of Descendants 2. For example, Mal, now more in touch with her good side, tries to convince Harry to also look for a better way of life. Harry, initially resistant, slowly starts to see the value in what Mal is saying. Their interactions could be filled with tension, humor, and moments of real connection as they navigate their changing identities.
Perhaps Mal would make friends with a Hufflepuff. This Hufflepuff could be really kind and inclusive, and they would accept Mal for who he is right from the start. They could introduce Mal to the Hufflepuff common room and all the cozy traditions there. Another possible friend could be a Slytherin who has a similar background to Mal and they understand each other's motives and ambitions in the magical world.
Evie could be one of her allies. They are friends, and Evie is smart and can offer good advice on how to rule. Also, Jay might be on her side. He's strong and brave, which would be useful for protecting Mal as she tries to become queen.
For Mal, an actor like Tom Holland could be a great choice. He has that youthful charm and the ability to play a character who is in a strange situation. For Zeus, someone like Liam Neeson would be perfect. His deep voice and powerful presence would really bring the character of Zeus to life.
One great Mal and Ben fanfiction could be about their adventures after the events of Descendants 2. Maybe they go on a secret mission to another isle to help some lost souls. It could be filled with magic and their growing relationship.
A great idea for a fanfiction could be a time - travel story where Harry and Mal are sent back to the past, perhaps to the days when their parents first met. They have to figure out how to get back to their own time while also dealing with the knowledge they gain about their families' histories and how it affects their relationship in the present.
