One aspect of Yondu's human behavior in fanfiction is his relationship with Peter Quill. Fanfic writers might depict Yondu as a father figure in a more detailed way. They could write about how he teaches Quill about his heritage, not just through tough love like in the movies, but also through more patient mentoring, which gives a new dimension to their bond.
One common theme is friendship. Peter and Yondu have a unique bond, and many fanfictions explore how they support and care for each other. Another theme is redemption. Yondu has a complex past, and fanfictions often show his journey towards redemption through his relationship with Peter. Family is also a theme, as Yondu becomes like a father figure to Peter in some stories.
I really like 'The Adventures of Peter and Yondu'. This fanfic takes them on a new adventure, full of action and humor. They face new enemies and challenges, and in the process, their bond grows even stronger. It's a fun read that stays true to their characters.
There could be a Yondu OC fanfiction where the OC is from a long - lost species that has a special connection to Yondu's people. The story could revolve around how they discover this connection and how it changes the dynamics within the Ravager group. Maybe the OC has some ancient knowledge that helps Yondu make better decisions in dealing with other space - faring factions.
A common theme is redemption. Yondu has done some morally ambiguous things in the official story, and in fanfiction, he often seeks to make up for it. Writers like to show his journey towards becoming a better person in terms of his behavior towards others.
A theme that often pops up is cultural exchange. Yondu has his own unique culture as a Ravager, and an oc can bring in different values or beliefs. They can learn from each other, like the oc learning about the rough - and - tumble ways of the Ravagers and Yondu getting to understand a more gentle or different way of thinking from the oc. This can create a lot of interesting interactions and moments of growth for both characters.
