It's hard to say for sure. Comic satire is a matter of perception. Natty might have some aspects that could be interpreted as such, but it depends on various factors like the tone, content, and audience reception.
Natty Comics might have elements of satire in some of its works. Satire is a form of expression used to mock or criticize, and if you find those traits in the comics, then it can be classified as such. However, it's not uniformly satirical throughout.
A really cool Natty Gann fan fiction could be set in an alternate universe where she has special powers. For example, she could have the ability to communicate with animals in a more profound way than in the original story. This would lead to all kinds of new and exciting plotlines, like using her powers to solve mysteries or protect the wilderness.
You can start by looking on fan - fiction websites such as Archive of Our Own. There are often a lot of user - generated stories for various movies and characters there.
One possible storyline could be Natty Gann's further adventures in the wilderness. Maybe she discovers a hidden community and has to learn their ways to survive and help them. Another could be her facing new challenges in the city she returns to, like dealing with corrupt individuals who threaten the well - being of the working - class people she cares about.
One character that could be added is a female journalist. She hears about Natty's adventures and wants to write a story about her. This journalist could follow Natty around, asking questions and getting into some minor scrapes herself. Also, a young orphan boy who Natty takes under her wing. He idolizes her and she teaches him how to fend for himself.
