Well, one idea could be the exploration of how big foot and humans interact in a fictional world. Maybe they form an unlikely alliance to protect their shared forest habitat from some external threat.
Some fanfictions in this category could revolve around a big foot being adopted by a human family in a magical or alternate reality. The big foot would then have to adapt to human society, facing both humorous and heart - warming situations as it tries to fit in.
Big Foot is a cryptid, and there are no legitimate 'sex stories' as it is a creature of legend. However, in some fictional tales or really out - there interpretations, people might create wild scenarios. But these are not based on any real facts.
It adds a unique element. By combining the mystery of big foot with human experiences, it creates new storylines that are different from traditional fictional themes.
In 'Stiles is not human fanfiction', it's possible that Stiles is a spirit or a ghost - like being who has somehow attached himself to a human form. This would give him abilities such as being able to pass through walls or having some sort of psychic connection with the afterlife. His relationships with the other characters would also be very different. His friends might start to notice strange things about him, like how he never seems to get cold or how he sometimes seems to know things that he shouldn't. It could create a lot of tension and drama in the story.
A 'human in limbo' fanfiction could focus on a character who is trapped in limbo because of unfinished business. This unfinished business could be something like unspoken words to a loved one.

A human journalist could visit Zootopia to write a story about the city. But during their stay, they uncover a conspiracy that threatens the harmony between the different species.

One interesting idea could be a Dalek that has a malfunction and starts to develop human - like emotions. It might struggle between its programmed Dalek nature and these new emotions when interacting with humans.
A human to pokemon fanfiction could focus on a human being transformed into a Pokemon. They would have to learn how to survive in the Pokemon world, using their human knowledge to their advantage while also adapting to their new form.

This could create a really unique and exciting story as they navigate their new life and interact with other Pokemon.
