To be honest, I haven't come across any widely popular 'star hates marco fanfiction' stories. But in general, a story might become popular if it has a really engaging plot. For example, if the reason for Star hating Marco is something really unexpected like Marco accidentally releasing a powerful and dangerous spell on Star's family. If the writing is good and the characters are well - developed in that fanfiction, it could potentially gain popularity, but as of now, I don't know of any.
I'm not entirely sure specifically as it depends on the individual fanfiction. It could be a work where the character Star has some sort of negative feelings towards Marco in a fictional scenario created by the fanfic writer. Maybe there was a plot twist in the original story that led the writer to explore this concept of animosity between them.
One popular theme is romance. Fans often explore the relationship between Marco and Star, whether it's a slow - burn romance or a more immediate attraction. Another theme is adventure. Given the nature of the show, fanfictions might continue their adventures in different dimensions or against new enemies.
Some fanfictions focus on their role in saving their world or other worlds. They might have to face powerful enemies, and in the process, their characters grow and change. There are also fanfictions that play with the idea of time travel, sending Star and Marco to different points in their own history or the history of their world.
Marco could be a fan, a writer, or a character created specifically for this concept. Without more context, it's hard to say exactly who he is.
Yes, there are some out there. You can try looking on popular fanfiction websites like Archive of Our Own. Some might focus on their relationships and adventures together in a creative and engaging way.
Love and romance is a very popular theme in Star and Marco lemon fanfiction. Fans often write about the potential romantic relationship between them.

There can also be themes related to sacrifice, like one of them sacrificing something important for the other in the story.
One popular plotline could be the daughter inheriting unique powers from both Star and Marco. For example, she might have Star's magic wand abilities combined with Marco's karate skills. Another could be her navigating the complex politics of Mewni as a half - human, half - Mewman. She could face challenges in being accepted by both worlds and have to prove herself worthy. Maybe she embarks on a quest to find a lost magical artifact that was important to her parents, which would lead her on an adventure filled with new friends and enemies.
Janna is another popular character. She's known for her mischievous nature. In future fanfiction, she could be involved in some wild adventures with Star and Marco, perhaps using her unique skills and knowledge to help them out of tight spots or getting them into even more trouble.
A popular theme is alternate universes. Writers create different versions of the Star Butterfly and Marco story, where things are completely different. Maybe in one universe they are enemies, or in another they are already married and ruling a kingdom. Another theme is self - discovery.
