The baby could be a really interesting mix. Maybe it would have Finn's human features like his hair color and some of his facial structure, but also have the candy - like features of Princess Bubblegum. So it could have pinkish skin or some sort of candy - themed markings on its body.
The baby could have Finn's blue eyes and Princess Bubblegum's pink hair. It might also have a small crown - like feature on its head, just like Princess Bubblegum, but in a more baby - friendly version. And its clothing could be a mix of Finn's adventuring gear and the regal outfits of the Candy Kingdom.
Well, it could change the power dynamics. Finn being a human hero and Princess Bubblegum a powerful ruler, their baby might inherit unique abilities. It could also bring a new era of peace or new threats as different factions might react differently to this new addition. For example, the Ice King might see the baby as a new target for his schemes or as a potential way to gain some sort of power.
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.
Jake, Finn's best friend, would probably be a very protective and fun 'uncle' to the baby. He might use his shape - shifting abilities to create interesting playthings or protect the baby from harm.
One possibility is that the story could focus on how Finn and Flame Princess adjust to their new roles as parents. They might face challenges in protecting their baby from various threats in the Land of Ooo.
The Ice King could be an antagonist. He might be jealous of their relationship and the new baby. He could try to kidnap the baby to have someone to care for him. Another potential antagonist could be some of the more traditional Candy People who don't approve of Marceline being with Princess Bubblegum and having a baby together. They might try to separate the family.
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.
It could show a chubby and cute Nixon with big eyes and a pacifier.
The baby might have Bella's big, expressive eyes and Damon's dark, tousled hair. Maybe it would inherit Bella's pale complexion and Damon's sharp facial features. Since they both have a certain allure in their respective shows, the baby could be extremely beautiful or handsome, with an otherworldly charm.
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.
