Well, a frequent theme is the exploration of their different personalities. Tom is a demon with his own set of characteristics, and Marco is a human. Their differences can lead to some interesting interactions in fanfiction. Also, the theme of acceptance is quite common. They have to accept each other's flaws and differences as their relationship progresses. And there's often the theme of facing challenges together, whether it's dealing with other characters from the show or some new threat created by the writer.
One common theme is friendship turned into something more. Since they start as friends in the show, many fanfictions explore how that relationship could develop romantically. Another theme is self - discovery. As they interact in these stories, both Tom and Marco might learn more about themselves. And of course, there are often themes related to magic and adventure, as that's a big part of the 'Star vs the Forces of Evil' universe.
Love and friendship are also big themes. Their relationship is often portrayed as a complex mix of both. In some fanfictions, they start as friends and slowly realize there are deeper feelings. There's also the theme of forgiveness. Given their past conflicts, they have to forgive each other for things that have happened. This can be really well - explored in fanfiction, like when Star forgives Tom for his outbursts in the past, and it helps them move forward in their relationship.
One common theme is friendship. Since Marco has many friends in the show, fanfictions often explore the depths of his friendships, like how he supports his friends and how they support him in return.
One common theme is adventure. Since they are both involved in battles against the forces of evil in the show, fanfictions often continue this trend with them going on new quests. Another theme is friendship - turned - romance. Their close friendship in the series is a great base for writers to develop a romantic relationship in fanfiction.
Yes, there are some great ones out there. You can start by looking on popular fanfiction websites like Archive of Our Own. There, you'll likely find a variety of stories exploring the relationship between Tom and Marco. Some might focus on their friendship evolving into something more, while others could be set in alternate universes where their relationship takes different twists and turns.
One common theme is identity. Since Marco is now a female, exploring how this new identity affects her relationships and her role in the story is often seen. For example, how does she interact with Star differently now? Another theme is power. Some fanfictions give Fem Marco new powers, and the exploration of how she uses and controls these powers is a big part of the story.
One common theme is the exploration of a forbidden love. Since Marco and Moon are from different generations and have different roles in the show, their relationship often defies the norms, which makes for an interesting and often emotional story.
There are many great fanfictions about Star and Marco. Some might focus on their adventures that could have happened off - screen in the show. For example, a fanfiction could explore a parallel universe where they have different powers but still their strong bond remains.
The appeal lies in the fact that both Marco and Tom are complex characters. In fanfictions, authors can take these characters and put them in new situations. For example, in some 'Marco x Tom' fanfictions, they are forced to rely on each other in a world where Star is absent. This forces them to understand each other better and develop a relationship that may not have been possible in the original show. It gives fans a chance to see different sides of these characters and how they interact in a more intimate setting.
I've heard of a fanfiction where Marco and Tom team up to save Star from an unknown danger. In this 'Marco x Tom' fanfiction, their characters are really well - developed. The author focuses on how their different personalities - Marco's determination and Tom's fiery nature - work together. It's really interesting to see how they gradually become closer friends and perhaps something more as they face this common threat.
One interesting idea could be exploring a darker side of Marco's character. Maybe he has some hidden powers or motives that are revealed in the fanfiction. Another idea could be his relationships with other characters in this 'evil' scenario. For example, how does his friendship with Star change when he takes on this new, darker persona.
