Simon, if he makes an appearance in the fanfiction, would have a very different dynamic with Marceline. He has a long history with her and his wisdom could play a crucial role in helping her understand and manage her 'vampire in heat' situation. His presence could also bring up a lot of memories for Marceline, which would add depth to the story.
The Ice King and Marceline have a complex relationship in Adventure Time. The Ice King is often a bit of a nuisance, but Marceline, being a vampire, has her own unique way of dealing with him. Sometimes they're at odds, like when the Ice King's crazy schemes disrupt Marceline's laid - back vampire life. But other times, there's a strange sort of understanding between them.
The popularity of Finn and Marceline as a couple in fanfiction stems from multiple factors. In the source material, they have a unique bond. Finn's pure - heartedness and Marceline's edginess create a fascinating contrast. Their relationship is also one that can be developed in many different ways. Fanfiction writers are drawn to the idea of exploring how Finn's heroic nature might be influenced by his love for Marceline, and how Marceline's guarded heart could open up to Finn. Additionally, the fact that they come from different worlds, with Finn being a human and Marceline a vampire, adds an extra layer of intrigue to their potential relationship.
The plot is crucial. It shouldn't just be about the 'lemon' aspect. A good plot could involve Marceline's relationships, her past, or her adventures in the Land of Ooo. Maybe there's a mystery she has to solve, or a conflict with another character that adds depth to the story. And of course, the romantic or sexual elements, if done tastefully, can enhance the overall story.
One great Finn Marceline fanfic is 'The Adventure Beyond the Night'. It beautifully weaves their relationship, showing how Finn's courage and Marceline's mystery come together in a story full of adventure. Another one could be 'Finn and Marceline's Unusual Bond', which focuses on the development of their unique friendship and how it might turn into something more in a very heartwarming way. And 'Marceline's Influence on Finn' is also interesting, as it delves into how Marceline's presence affects Finn's growth and understanding of the world around him.
In the context of Adventure Time, Finn and Marceline having a romantic or sexual relationship in fanfiction can be a controversial topic. Adventure Time is a show aimed at a wide audience, including children. Such explicit content in fanfiction goes against the family - friendly nature of the original show. So, it is not appropriate in the sense that it strays far from the intended spirit of the series.
One key event is when the Ice King's actions accidentally disrupt Marceline's territory. Another is their occasional team - ups, like when they face a common threat in the Land of Ooo. And there's the time when Marceline tries to make the Ice King remember his past as Simon.
One popular Finn and Marceline love fanfiction could be 'The Unseen Bond'. It beautifully explores their relationship with a lot of emotional depth.

Writing such fanfiction is not acceptable. It can also have a negative impact on the perception of the original characters and the overall fandom. There are so many other positive and creative ways to write fanfiction, like exploring their friendship, adventures, or character development without delving into inappropriate sexual content.
