The scarecrow - like creatures are very interesting. In fanfiction, you could give them a backstory. Maybe they were once normal farmers who were cursed by an evil witch. You could also write about the girl with the black ribbon around her neck. What's beneath that ribbon? Is it something truly horrifying? Exploring her secrets and her relationship with the other characters in the story would be fascinating.
The Pale Lady is definitely an interesting character to write about. She has this eerie, otherworldly quality. You could explore her origins, like where she came from and why she haunts the places she does. Another one is Harold. He has a really creepy appearance and his actions in the stories are quite menacing. Writing about his motives and what drives him to be so evil could make for a great fanfiction.
Barnabas Collins is likely one of the most popular. He was a central figure in the original and his vampire nature gives a lot of room for creative writing in fanfiction. Also, Angelique, with her complex relationship with Barnabas, is often written about.
Circe is a very interesting character for greek fanfiction. She has the power of magic and transformation. Writers can explore how she uses her powers to manipulate those who come to her island. Also, Odysseus is a classic character that is always interesting to write about in new ways. His long journey home can be reimagined, or his interactions with other mythological beings can be expanded upon.
Gerry is definitely one of the most interesting. His unique love for animals and his innocent yet inquisitive nature offer a lot of room for creativity. Writers can create all kinds of scenarios where Gerry discovers new species or has heart - warming interactions with the local wildlife.
Alice is a very interesting character to write about. Her ability to see the future gives so many possibilities for plot twists. Writers can explore how she might use or be haunted by her visions in different situations. Another is Jasper. His past as a Confederate soldier and his struggle with his bloodlust can be delved into deeply.
For me, Sol Star is an interesting character to write about in deadwood fanfiction. He's often in the background but has his own dreams and desires that can be further developed. Then there's E.B. Farnum. His conniving and somewhat pathetic nature can be a source of great comedic or tragic stories. And of course, Wild Bill Hickok. His legend and his short time in Deadwood provide a lot of inspiration for different storylines.
Link is a very interesting character. His complex backstory with the Triforce and his many adventures in Hyrule give a lot of material for fanfiction. You can write about his internal struggles, like when he has to make tough decisions to save his kingdom. Another interesting one is Kirby. His cute appearance but powerful abilities create a contrast. You can write about Kirby exploring new planets and befriending other SSB characters.
In my opinion, the Death Knight can be a very interesting character for quake fanfiction. It has this dark and menacing presence. You could write about its past, like how it became this powerful and feared entity. Another interesting character is the Fiend. You can explore its relationship with other creatures in the Quake world, or how it hunts its prey. And the Vore is also an interesting one. It has this unique and grotesque appearance, and you could write about how it came to be in the Quake universe.
Yato is definitely one of the most interesting. His complex personality, with his past as a war god and his current quest for recognition, gives a lot of material for fanfiction. Hiyori is also great. Her ability to cross between the worlds and her kind - hearted nature make her a fascinating character to explore in different scenarios. And Yukine, with his growth as a shinki and his relationship with Yato, offers a lot of potential for interesting stories.
Elise is a really interesting character to write about. Her grace and skill on the slopes make for great descriptions. Mac is also cool. His laid - back attitude combined with his amazing stunts gives a lot of material for fanfiction. And then there's Zoe. Her bubbly personality and determination can add a lot of charm to a story.
Max Sterling is an interesting character for robotech fanfiction. He's an ace pilot with a cool - headed nature. His relationship with Miriya, a Zentraedi who becomes his wife, is full of potential for stories. Lisa Hayes is also great. Her strong leadership and her evolving feelings for Rick Hunter can be the focus of many interesting plots. Then there's Khyron, the unpredictable Zentraedi who always brings chaos and danger.
