Survival is a common theme. Since Daryl Dixon is from a post - apocalyptic world, many fanfictions about his younger self also revolve around how he learned to survive in difficult situations.
Appropriateness varies. If the abuse fanfiction is part of a story that ultimately aims to heal or show growth, it might be okay. But if it makes light of abuse or uses it in a way that makes viewers or readers uncomfortable without any redeeming qualities, it's not appropriate. Writers should be aware of the impact their work can have on the fan community.
Sure. One popular 'little Daryl Dixon fanfiction' might be those that focus on his early days in the apocalypse, like the story where he first learns to track zombies more efficiently. It gives a great insight into his character development.
One great Daryl Dixon little brother fanfiction is 'The Dixon Brothers' Bond'. It delves deep into their relationship before the apocalypse, showing how they supported each other through tough times in their family. Another one could be 'Daryl's Little Brother: A New Hope' which focuses on the little brother's journey to find Daryl during the chaos of the zombie outbreak. There's also 'Little Dixon's Adventure' which has the little brother facing his own set of challenges in the post - apocalyptic world while trying to live up to Daryl's name.
Daryl Dixon isn't gay in the comics. The storylines mainly revolve around his adventures and struggles in a post-apocalyptic world, not his sexual orientation.
