One great fanfiction with this concept is 'Baby Dean's Adventures'. It has a really cute take on how the other characters deal with a baby Dean. They struggle at first but then it becomes a heartwarming story of protection and family.
The relationship between Dean and the idea of a baby is really interesting. It shows a different side of Dean, his protective and nurturing side which we don't always see in the show.
Dean would become more protective. His tough - guy exterior would soften as he takes care of the baby. He'd be more cautious in his hunts, not wanting to leave the baby unprotected.
You can try websites like Archive of Our Own (AO3). It has a large collection of Supernatural fanfictions, including those related to Dean and baby - themed ones. Just use the search function and type in relevant keywords.
Well, perhaps the baby is a key to closing a major portal to the underworld. Dean discovers this and has to raise the baby while also preparing it for this great task. Along the way, he gets help from Sam and other friends. They face various challenges from demons who want to stop the baby from fulfilling its destiny.
Obviously, Dean and Sam are main characters. They are the protective older brothers. And then there's the baby sister, who is likely a central figure as well, with her own personality and role in the fanfiction. There might also be other recurring characters from the 'Supernatural' universe like Castiel who could play important parts in the story.
One interesting storyline could be the baby sister having special powers that she has to learn to control. Maybe she can communicate with spirits in a unique way, different from Sam and Dean, which adds a new dynamic to their hunting adventures.
In fanfiction, Dean as a Prince of Hell can open up many interesting storylines. One possibility is that his character becomes darker and more conflicted. He might struggle with his newfound powers and the evil that comes with being a Prince of Hell. His relationships with Sam and Castiel would also be severely tested as they try to figure out how to deal with this new Dean.
One great aspect of Castiel and Dean in fanfiction is their dynamic. Their relationship, which is complex in the show, can be explored even further in fanfictions. Writers often delve into their unspoken bond, creating scenarios where they support each other in ways not shown in the original series. For example, some fanfictions might have them going on a road trip together just for the sake of exploring new places and having deep conversations about their pasts and futures.
In Supernatural fanfiction, Dean often has different relationships. His girlfriends can range from original characters created by the fanfic authors to characters from the show's universe in alternate scenarios. For example, some fanfictions might pair him with a hunter from another part of the world, adding new dynamics to his character as he navigates a relationship while still dealing with hunting demons and monsters.
