The baby could be an orphan from a nearby village that has been attacked. Kagome stumbles upon the baby while on her travels with Inuyasha. Since she has a big heart, she can't just leave the baby there, so she takes it with her.
The baby could be a lost elf child from a different part of the forest. Maybe their family was attacked by some dark force and Thranduil finds them by chance.
The baby could be a half - demon, related to some other important character in the series. Maybe it's the offspring of a character Sesshomaru has some history with.
Edward Cullen is one of the most common baby daddies in Twilight baby daddy fanfiction. Since he's the main male lead in the original series and has a complex relationship with Bella, it's natural that many fanfiction writers explore the idea of him as a father. Jacob Black is also a popular choice. His relationship with Bella was also significant, and in some fanfictions, he could end up being the baby daddy in an alternate storyline. Another character who might be the baby daddy in some fanfictions is Aro from the Volturi. His powerful and mysterious nature makes for an interesting take on being a father in the Twilight - inspired stories.
Adventure is also common. They could be on a quest to find a lost item or to explore a new part of their world. It makes for exciting reading as they face various challenges as babies. For instance, they might encounter a small stream that they need to cross but are too small to do so easily. And they have to figure out a solution together. This kind of adventure - based theme is quite popular.
It could be Hinata. Since they are in a relationship in the original series, it would be a natural choice. Hinata would be a loving and caring mother, and her gentle nature would be a great influence on the baby.
Wart could also be an antagonist. He might try to take over the Mushroom Kingdom where Baby Mario and Baby Peach live. He could send his minions to stop the two from getting help or finding special items that can defeat him.
In general, it's not considered appropriate. The idea of a baby dying is a very distressing and sensitive topic. While fanfiction can explore dark themes, this one crosses a line for many people as it involves the death of a vulnerable and innocent being, which can be extremely disturbing.
Baby reader fanfiction is a type of fan - made fictional writing where the main character is often a 'baby' in some sense. It could be that the story is told from the perspective of a young or innocent character, or it might involve scenarios where a more mature character takes care of this 'baby' - like character within the context of the fan - created universe. For example, in a superhero fanfiction, the 'baby reader' could be a new recruit who is inexperienced and the other characters have to guide and protect them.
Well, 'forced baby fanfiction' is not a positive or healthy type of fan - created work. It could potentially involve elements like forcing a certain plotline on a baby character that may be disturbing. For example, it might be creating a story where a baby is made to be part of a dangerous or inappropriate situation that is not in line with the well - being and proper treatment of children, even if it's in a fictional fan - based world.
