You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions from various fandoms, including the Supernatural fandom which might have some great Bobby John stories.
There might be a fanfiction where Bobby John forms an unlikely alliance with other supernatural beings. For example, he teams up with a friendly vampire who has a moral code. They journey together to solve a mystery that could destroy their world. In this story, we can see Bobby John's character develop as he learns to trust someone he was initially afraid of.
One great fanfiction about Daddy John in Supernatural could be one where he mentors Sam and Dean in a more in - depth way about hunting family secrets. It might explore his past experiences and how they shape his parenting style.
Well, in fanfiction, Bobby's daughter can be portrayed in many ways. Sometimes she's a tough hunter like her father. She might be shown as having a special connection to the supernatural world, perhaps with a unique ability to sense spirits or something. And often, she's a key figure in helping the main characters solve mysteries related to the show's supernatural elements.
One great 'John Constantine Supernatural Fanfiction' is 'Constantine's Cursed Case'. It has a really engaging plot where Constantine teams up with the Winchester brothers in a way that feels true to the characters. The author does a wonderful job of capturing Constantine's snarky attitude and his unique brand of magic.
I really like 'John Winchester's Redemption'. It's a story about John trying to make up for his past mistakes and be a better father. 'The Lost Years of John Winchester' is also fascinating as it fills in the gaps in his life that the show didn't fully explore. And 'John's Final Hunt' is a heart - wrenching story that shows his last stand against the supernatural forces, while also reflecting on his life and his relationship with his family.
Often, there are plotlines where she teams up with Sam and Dean. They might not trust her at first because she's Bobby's daughter and they're worried about her getting hurt. But then she proves herself to be a capable hunter. There are also stories where she gets trapped in a different dimension or time period related to the supernatural and has to find her way back while dealing with the local supernatural threats there.
One popular 'X men Bobby and John fanfiction' is 'Frosty Bonds' which explores their relationship in a post - apocalyptic mutant world. It has great character development.
Another theme is sacrifice. John often has to sacrifice his own well - being or personal desires to ensure the safety of Sam and Dean. Fanfictions expand on this, showing different scenarios where he makes tough choices.
