A Marceline and Finn kiss in fanfiction can be really interesting. It might show a different side of their relationship. Maybe in the fanfic, it's a moment of realization for both of them, a deeper connection that goes beyond their usual adventures. It could also be a turning point in the story, leading to new plot developments like them facing challenges together as a couple or dealing with how their friends react to this new relationship.
Yes, there are quite a few out there. You can start by looking on fanfiction websites like Archive of Our Own. Some fanfictions might focus on different scenarios leading up to the kiss, like an adventure they go on together which deepens their bond and results in that special moment.
A plotline might involve their friends' reactions. After the kiss, Jake might be really surprised and have to adjust to the idea of his best friend being with Marceline. Princess Bubblegum could also have a reaction, perhaps being a bit jealous if she has some unspoken feelings for Finn. And there could be a plot where Finn and Marceline have to keep their relationship a secret at first because they're not sure how everyone will react.
The popularity might come from the fact that Finn and Marceline have a very interesting dynamic in the original show. Their different personalities, Finn being a young and energetic adventurer and Marceline being a centuries - old vampire, create a lot of potential for unique storylines leading to a kiss.
One great fanfiction might be 'Finn and Marceline's Secret Moment'. It could explore the emotions behind their kiss, perhaps how Finn's pure heart and Marceline's complex nature come together in that moment. Another could be 'The Kiss that Changed Everything', which might focus on how this kiss affects their friendship and their roles in the Adventure Time world.
In one fanfiction, Finn and Marceline start off as friends who slowly realize their feelings are deeper. Finn, always the brave adventurer, begins to notice how much he misses Marceline when she's not around. Marceline, for her part, sees Finn's kindness and courage in a new light. One day, during a dangerous adventure where they protect the Candy Kingdom together, they share a moment of closeness that makes their relationship shift towards love.
In fanfiction, their relationship could be developed by having them team up for a noble cause, like saving the Candy Kingdom from a new threat. During this mission, they face challenges that require trust and cooperation. Finn might learn to be more patient with Marceline's mood swings, and Marceline could come to appreciate Finn's unwavering optimism. Also, they could have a friendly competition that turns into a deeper understanding of each other's strengths and weaknesses.
Yes, there are some out there. You can try searching on popular fanfiction websites. Some might focus on the idea of Finn and Marceline having a baby in an alternate universe where their relationship has developed in that direction. They could be dealing with the challenges of raising a child in a post - apocalyptic world like in the 'Adventure Time' setting.
One great Finn x Marceline fanfic is 'Adventure in the Night'. It beautifully explores their relationship in a post - apocalyptic setting. The author does an amazing job of portraying Finn's growth and how he and Marceline interact in this new world.
I really like 'Finn and Marceline's Unlikely Alliance'. It shows a unique take on their relationship where they start off as reluctant partners but end up having a strong bond. There's also 'Marceline's Song for Finn' which is a more emotional fanfiction that focuses on Marceline's feelings towards Finn through her music.
