Family is a very common theme. Just like in the show, fanfictions often explore the relationships within the Hill family, like Hank's attempts to raise Bobby in a traditional way. Another common theme is small - town life in Arlen. Writers like to delve into the quirks of the town and its residents.
Friendship is also prevalent. For example, the friendship between Hank and his buddies Dale, Bill, and Boomhauer. Fanfictions might show them getting into various situations together, like a fishing trip gone wrong or trying to fix something in the neighborhood. And of course, the theme of Texas pride is often there, with characters showing their love for their state through various actions and dialogues.
One common theme could be Peggy's strong - willed nature being a factor in the relationships depicted in the fanfiction. Maybe her determination in love or in dealing with family situations while still having that 'lemon' aspect.
One common theme is physical injury. Maybe she gets seriously wounded in a battle against a powerful villain. For instance, she could be caught in the crossfire between the Avengers and a new threat, like a powerful alien race. Another theme is emotional turmoil. This could be due to her being forced to make tough decisions in her role at SHIELD, such as choosing between loyalty to her superiors and what she believes is right, which causes her a great deal of internal conflict and emotional pain.
One common theme is friendship. They both work in the same universe, so many fictions explore how they support each other as friends. Another theme could be teamwork, as they might be on missions together.
One common theme is the journey of the pregnant character dealing with the challenges of impending motherhood, like how to balance it with their personal life in the One Tree Hill universe. For example, they might be struggling with school or relationships while being pregnant.
One common theme is the battle against supernatural forces. Since both 'Supernatural' and 'Silent Hill' deal with the supernatural, in fanfictions, the characters often team up to fight demons, ghosts or other malevolent entities from both universes.
It could be about Naruto characters in a 'King of the Hill' - like scenario. Maybe Naruto is competing to be the king of a hill in the ninja world, with different battles and challenges against his friends or foes.
I'm not sure specifically as 'adult fanfiction' often contains inappropriate content which I can't promote. But generally, 'King of the Hill' is a popular show. Fanfiction related to it usually involves fans creating their own stories based on the show's characters and settings in a non - official capacity.
A theme of trust is also quite prevalent. Since they both work in a world full of secrets and danger, exploring how they come to trust each other can make for an interesting fanfiction. Sometimes, there are also themes of redemption, especially when it comes to Black Widow's past and how Agent Hill might help her come to terms with it or vice versa.
Love is a very common theme. The relationships between the characters, whether it's romantic or platonic, are often explored in depth during this summer setting. For example, new romances might start or old ones might be rekindled.
