Sam's baby sister could also be depicted as a mediator. In a story where there are conflicts between different groups of Transformers on Earth, her naivete and lack of prejudice could help bridge the gap. She doesn't understand the reasons for their fighting and just wants everyone to get along, which could gradually influence the Transformers to find common ground.
One possible fanfiction could be about Sam's baby sister being born with a special connection to the Transformers. Maybe she can communicate with them telepathically. This could lead to all sorts of adventures where she helps the Autobots in ways that Sam couldn't. For example, she might be able to sense when the Decepticons are planning a surprise attack and warn the Autobots in time.
Often, baby woes in Transformers fanfiction are related to growth and development. A young Transformer may have difficulty controlling its abilities as it grows. It could accidentally cause harm to its friends or surroundings while trying to figure out how to use its powers, like a youngling learning to walk but constantly stumbling.
One possible fanfiction could be about Sam and Mikaela starting a family. Maybe they find an abandoned Autobot baby. Sam, with his experience with the Autobots, wants to take it in and Mikaela is initially hesitant but is won over by the baby's cute beeps and whirs. They then face the challenge of raising a baby that has unique robotic needs while also trying to keep it a secret from the world.
Sam and Mikaela would handle it with love. Sam, being the adventurous type, would be excited to introduce the baby to the Autobot world. Mikaela, on the other hand, would be more focused on the day - to - day care. They'd probably have to make a special nursery that could also double as a safe haven from Decepticon attacks.
One popular type of 'Family Matters' fanfiction involving Baby Sister Sam could be a story where she discovers a hidden talent. For example, she might find out she has an amazing singing voice and then has to deal with the newfound attention it brings in the family and at school.
He can be depicted as a bit of an eccentric in fanfiction. His intense focus on his scientific work might lead to some humorous situations. Maybe he gets so caught up in his experiments that he forgets about the time or causes some minor chaos in the human - Transformer shared environment.
In Supernatural fanfiction, Sam having cancer can be portrayed in various ways. Some authors might use it as a way to add more emotional depth to his character. They could show his struggle with the illness while still dealing with the supernatural threats. For example, he might be weaker physically but still determined to fight demons, which creates a contrast between his human vulnerability and his heroic side.
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.
In some Transformers fanfiction involving an 'abused Harry Potter' concept, it might show Harry being out of his familiar wizarding world and facing new forms of hardship. For example, he could be bullied by certain Autobots or Decepticons who don't understand his human - wizard nature. This can be a way to explore his character's resilience in a completely different and often harsher environment than Hogwarts.
Another way is to follow Supernatural fanfiction writers on social media platforms. They often share their works or recommend other good stories. For example, on Twitter, there are many Supernatural fanfic writers who are active and can give you great suggestions for Sam and Dean baby sister fanfictions.
