Their relationship could also develop on a more personal level. They might start a family, which would be an interesting concept considering Finn is a human and Princess Bubblegum is made of candy. They would have to figure out how to raise their children with both of their unique cultures and abilities.
One possible plot twist could be that an old enemy returns to try and stop the wedding. Maybe the Ice King, jealous of Finn's happiness, decides to freeze the whole Candy Kingdom right before the ceremony. Finn would then have to fight through the ice and snow to save his future with Princess Bubblegum.
In some fanfictions, she might. It could be due to a plot twist where her scientific experiments or her role as a princess with a lot of power might accidentally or intentionally cause harm to Finn. However, it depends on the specific interpretation and storyline of the fanfiction.
Well, it's possible. In the Adventure Time world, the characters have complex relationships. Fanfiction often delves into uncharted territories of these relationships. But keep in mind that not all fanfiction is of the same quality. You might have to sift through a lot to find one that really satisfies your interest in this particular concept. It's also important to note that different fanfictions may handle this idea in different ways, some might be more light - hearted while others could be more serious in their exploration of Finn and Princess Bubblegum in this situation.
I'm not sure specifically about 'lemon' fanfiction as it often refers to inappropriate or adult - themed content. However, there are many great Finn and Princess Bubblegum fanfictions that focus on their friendship, adventures together, or the development of a more innocent relationship. You can try searching on fanfiction platforms like Archive of Our Own and filter for appropriate stories.
Finn is brave and always ready for an adventure. His fearless nature can lead to many exciting situations in fanfiction. For example, he can be the one to drag Princess Bubblegum out of her lab and into the unknown. Princess Bubblegum, on the other hand, is highly intelligent and has a strong sense of responsibility for her kingdom. This contrast between their personalities can create great storylines, like Finn teaching Princess Bubblegum to be more spontaneous while she teaches him about science and leadership.
It could be a very interesting story. Maybe it would explore how Finn and Princess Bubblegum deal with the unexpected situation, like their reactions and how they plan for the future.
Love in the face of danger is also a popular theme. Given the many threats in their world, fanfictions might depict how their love for each other gives them the strength to face those threats. It could be a monster attack or a problem within the Candy Kingdom, and their love is what keeps them going and helps them find solutions.
Maybe in the fanfiction, there's a misunderstanding at first. Finn thinks Bubblegum only sees him as a friend. But then some magical event occurs that makes their true emotions surface. For example, a love - inducing spell goes wrong and affects everyone in the Land of Ooo except Finn and Bubblegum. As they try to fix it, they get closer and closer until they finally kiss. This kiss could be the key to reversing the spell.
One possible scenario is that she's trying to protect the Candy Kingdom from a new threat and Finn's impulsive actions get in the way. So, in her attempt to stop him from endangering the kingdom, she might accidentally hurt him. Another could be that she's under the influence of some sort of mind - controlling substance or magic and she ends up harming Finn without realizing it.
