Well, in some fanfictions, the plot might focus on the long - term effects of the Blood Moon on Star and Marco's relationship. Maybe they start having strange dreams or premonitions related to it. Or perhaps there's a plotline where an enemy tries to use the power of the Blood Moon Ball to their advantage, and Star and Marco have to team up in a new and unexpected way to stop them.
One interesting plotline could be an alternate version of what happened during the Blood Moon Ball. For example, Star and Marco might have had a more in - depth conversation about the implications of the Blood Moon's magic. Another could be a story where the events of the Blood Moon Ball are re - imagined from the perspective of a minor character who was present at the ball.
Star and Marco are obviously very popular. They are the main characters from the original series, and the Blood Moon Ball is a significant event in their relationship. So in fanfiction, they often take center stage. Another popular character could be Tom, especially when it comes to exploring the love triangle aspect between him, Star, and Marco.
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.
One interesting Star and Marco fanfiction could be about their adventures in a new dimension. Maybe they discover a land full of magical creatures that are different from anything in Mewni or Earth. Another could be a story where they have to work together to solve a mystery in Echo Creek that involves a strange spell.
One possible plotline could be that Marco gets a new friend or a love interest and Star starts to feel left out, leading to her jealousy. Another could be that Marco achieves something that Star has been striving for and her envy turns into jealousy.
One interesting plot could be Star and Marco exploring new dimensions together in the future. They might encounter strange creatures and have to use their combined powers to survive.
A common plotline is Snape being an observer at the Yule Ball. He watches the students and teachers interact, and through his observations, we learn more about his character. For example, he might notice a particular student's behavior and it makes him reflect on his own past.
One idea could be that Star has a Mewberty episode in a new dimension while Marco tries to find a way to calm her down using his knowledge of her previous Mewberty forms. Another could be a story where Marco accidentally triggers Star's Mewberty transformation during a school event, and they have to deal with the chaos together while also hiding it from others.
Some interesting ideas include the alteration of their character arcs. A gender - swapped Star might have different goals in life. Maybe instead of focusing on princess - like things, a male Star could be more interested in proving his strength in a more traditional masculine way. For Marco, if he were female, her relationship with Jackie could be very different. It could be more of a sisterly bond or a friendly rivalry. And the overall tone of the story could change too. It might become more about breaking gender stereotypes in the magical world they live in.
Another plot could involve the other characters' reactions to Star's Mewberty. For example, Jackie might be a bit jealous or confused about the new dynamic between Star and Marco. And Janna could be intrigued and try to use the situation to her advantage in some comical ways.
One interesting plotline could be the origin story of the Blood Rose in the RWBY universe. Maybe it's a weapon with a hidden power that the main character discovers.
