Merlin himself is of course very interesting. His complex character with his magic and his loyalty. Morgana is also quite fascinating as she has her own struggles and powers.
Obviously Merlin is a key character. But in fanfiction, characters like Gwaine can be really interesting. He's this fun - loving knight in the original, and in fanfiction he can be developed further. Also, Nimueh can be an interesting character as she has her own motives and magic that can be explored in different storylines.
In Merlin Once Upon a Time fanfiction, Merlin is the most central and interesting character as his journey of magic and his role in the story are so complex. However, other characters like Uther also gain new dimensions. Uther, who was so against magic in the original, can be explored in fanfiction in terms of his possible change of heart or understanding of magic. And then there's Gaius, Merlin's mentor, whose wisdom and backstory can be delved into more deeply in fanfiction, making him a very interesting character as well.
Rick Dalton is quite interesting. His struggle to maintain his stardom in Hollywood makes him a complex character.
Perhaps the ambitious director character. He is constantly striving for success, trying to make his mark in Hollywood. His creative vision and his struggle to get his projects off the ground, while dealing with the politics and egos in the industry, make him an engaging character. He might be the one who drives the narrative forward with his big ideas and his determination to bring them to life.
Jace is a very interesting character to write about. His complex personality, being a skilled shadowhunter yet having his own inner turmoil, offers a lot of material. Clary is also great as she discovers her new powers and her place in the shadowhunter world. Magnus Bane is another one. His magical abilities and his flamboyant personality make for really engaging stories.
Snow White and Prince Charming are often popular. Their classic fairy - tale love story can be twisted and turned in interesting ways within the context of a cursed story. Emma Swan is also a favorite. Her strong - willed nature and her role as the savior in the original series make her a prime character for fanfiction writers to explore in a cursed scenario. Another popular character is Regina Mills. Her complex personality, with her history as the Evil Queen, offers a lot of room for creative exploration in a cursed 'Once Upon a Time' fanfic.
Ivy herself is often a very popular character. Since it's an ivy fanfiction, she's usually at the center of the story. Then there might be her love interests. If there's a romantic sub - plot, the male lead who has a relationship with Ivy would be popular too.
One popular theme is the exploration of Merlin's magic in different storylines. Another is his relationships, like his friendship with Arthur. Also, the struggle between good and evil is often a central theme.
Another interesting original character is a young boy who could communicate with animals. He became friends with Princess Tutu and helped her understand some of the deeper secrets of the forest. His ability to talk to animals provided unique perspectives and solutions to the problems they faced. He was also really cute and his interactions with the other characters were heartwarming.
There is. I've come across some interesting ones. A lot of these fanfictions play with the idea of the different magical systems in Merlin and Once Upon a Time. For example, how Merlin's ancient magic would interact with the magic in the fairy - tale world of Once Upon a Time. They often create unique and exciting plotlines that draw you in. It's really fascinating to see how authors blend the two universes together.
One of the popular vampire characters is probably Killian Jones (Captain Hook). In some fanfictions, he might be turned into a vampire or have some sort of vampire - related story arc. His complex character and his relationship with other characters in 'Once Upon a Time' make him a great candidate for vampire - themed stories.
One of the most popular characters might be the wise old wizard who lives on the outskirts of Golden Green. He is often sought after for his knowledge and magic. Another could be the brave young knight who defends the village within Golden Green from various threats. His courage and honor make him a favorite.
