I'm not sure if there is a 'good' one specifically. Fanfiction quality can vary greatly. Some might find certain crossovers interesting in terms of exploring the different universes of Naruto and Adventure Time (where Princess Bubblegum is from) colliding in a creative way, but lemon fanfictions often involve inappropriate or adult - themed content which is not acceptable in many platforms.
In such fanfiction, the lemon part usually implies a more adult - themed or steamy relationship exploration. However, it's important to note that this often goes beyond the boundaries of the original children - friendly Adventure Time series. Some writers might use it as a way to add a new dimension to their relationship, perhaps showing how they overcome challenges not just as friends but as lovers in a more intense setting.
The appeal might be the forbidden - like nature of their relationship in the original show. Fans are drawn to the idea of seeing what could happen if they had a more intimate relationship. It's like exploring uncharted territory.
One possible plot could be that Naruto somehow gets transported to the Land of Ooo (where Princess Bubblegum is from). He could team up with her to fight a common enemy, like a powerful new villain that threatens both their worlds. Naruto's ninja skills and Princess Bubblegum's scientific knowledge and leadership could be combined to defeat the foe.
The plot could involve a princess - like robot from another dimension coming to the Naruto world. She might be made of bubblegum - like material which gives her unique abilities. She could team up with Naruto and his friends to fight against a common enemy, perhaps using her bubblegum powers to trap foes or her robotic strength to overpower them.
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 if there are many specific fanfics with exactly this combination. You could try searching on popular fanfic websites like FanFiction.net or Archive of Our Own. Just type in the relevant keywords and see what comes up.
Sure. There are fanfictions that explore their backstories and how they became friends. Maybe Marceline teaching Princess Bubblegum about the vampire world in a platonic way, or Princess Bubblegum showing Marceline some new scientific discovery in the Candy Kingdom. It's all about building on their unique bond without any sexual undertones.
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.
