One common theme is fitting in. The new girl often has to find her place among the different monster cliques at Monster High. For example, if she's a new type of monster that no one has seen before, she might face some initial rejection but then slowly make friends.
A really cool 'Monster High new girl fanfic' that I've read focuses on a new girl who is a shape - shifter. She arrives at Monster High and is initially very shy about her abilities. But as the story progresses, she uses her shape - shifting skills to help her new friends out of various tricky situations.
One great 'Monster High New Girl' fanfiction could be about the new girl being a rare type of monster that no one has ever seen before. She brings new powers and a whole new dynamic to the school. For example, she might have the ability to control time, which causes all sorts of chaos and interesting plot twists at Monster High.
First, think about the character of the new girl. Decide what kind of monster she is, her personality traits, and what makes her unique. For example, if she's a mermaid - type monster, she might be shy but also very curious about the land - based monsters at Monster High. Then, come up with a basic plot. It could be something like her trying to fit in and make friends.
I really like 'Ghouls' Night Out' fanfic. It focuses on the main ghouls going on an adventure in the human world at night. It's full of fun and spooky moments, and it shows how the Monster High characters interact with human things in a really entertaining way. It also has some great dialogue that makes the characters feel alive.
The lamia is often quite popular. Her snake - like lower body gives her a unique and alluring appearance. She can be portrayed as mysterious and intelligent, which makes for an interesting character in fanfics.
In a 'Girl vs Monster' fanfic, the girl could be from a long line of monster hunters. She is the only one left in her family though. The monster she's up against is the one that killed her family. This adds an emotional depth to the story as she not only fights for survival but also for revenge. She might use her family's secret techniques to take on the monster.
You should focus on the relationships between the characters. Whether it's the friendship between Clawdeen and Draculaura or the rivalry between some of the monsters. Build on these relationships in your fanfic. And make sure to add some drama or conflict, like a big competition at Monster High or a misunderstanding between two characters that needs to be resolved.
A fanfic could explore their relationship in the context of a Monster High dance. Heath wants to ask Abbey to the dance but is really nervous. He finally gets the courage and asks her. Abbey is hesitant at first but then says yes. At the dance, they have a great time, dancing to the spooky music and showing off their monster -rific moves. They also have to deal with some jealous classmates who try to cause trouble between them, but in the end, their bond only grows stronger.
One possible aspect of a Naruto and Monster High fanfic could be the characters' interactions. For example, Naruto's determination and positive attitude might clash or blend with the unique personalities of the Monster High characters. Maybe Naruto could teach them about his ninja way, while the Monster High students introduce him to their spooky yet fun world.
