Another theme could be transformation. Maybe the female character has some sort of special connection with Ninetales that allows her to transform into a Pokémon - like form or gain some of Ninetales' powers. This can lead to interesting storylines where she has to learn to control these new abilities.
Another place could be FanFiction.net. However, the tagging system might not be as detailed as AO3. But still, there are many Pokémon - related fanfictions, and you might be able to find some that feature a female character with Ninetales by browsing through the Pokémon section and looking for relevant titles or descriptions.
Perhaps in a fanfiction, Houndoom gets lost in a strange, icy territory which is Ninetales' home. Ninetales finds the out - of - place Houndoom and at first is wary. But as Houndoom shows its gentle side, Ninetales starts to warm up to it. They then embark on a journey together to help Houndoom find its way back home, facing various challenges along the way.
One possible storyline could be about how Houndoom and Ninetales, coming from different elemental backgrounds, overcome their differences. Maybe they meet in a magical forest where they initially have a territorial dispute but gradually realize they have more in common. Their relationship could develop as they face challenges together, like a common enemy threatening their habitat.

One interesting fanfiction idea could be Ninetales' origin story. It might delve into how it evolved from Vulpix and the experiences that shaped it into the powerful Pokemon it is. This can add depth to the character and make for an engaging read.

Their offspring might be a unique blend of both. It could have the body structure of Houndoom with some of Ninetales' more elegant features, like its long, flowing tails. Maybe it would inherit Houndoom's horns but in a more refined way, similar to Ninetales' grace.
