Yes. Her stories are important. They carry the history of the Avatar world. They can teach the younger generation about the past battles and how they overcame difficulties.
I'm not sure if there are widely known 'feet fanfics' specifically for Avatar: The Last Airbender. Fanfic communities are vast, but this is a rather niche topic. However, there might be some hidden gems in smaller, more specialized fanfic groups or websites dedicated to the series.
She might tell stories about her adventures as an earthbender. For example, her experiences fighting against the Fire Nation and how she used her unique earthbending skills to overcome challenges.
Yes, there are many non - adult fanfics about Toph. You can find them on various fanfic platforms. Some might focus on her adventures, her friendships, or her growth as an earthbender. For example, there could be stories about her training new earthbenders or her interactions with the rest of the Gaang in different scenarios that don't involve any inappropriate content.
In some fanfics, Toph has to face off against a new breed of earthbenders who use a different style of bending that challenges her traditional ways. This forces her to adapt and grow. Another plotline could be Toph getting lost in a spirit world - like realm where the rules of bending are different, and she has to find her way back while also learning new things about herself and her powers.
Well, these fanfics might have unique aspects like the cultural significance of feet in the Avatar world. In some cultures shown in the series, footwear or the lack of it could have meaning. So a fanfic could play around with that, showing how characters from different nations view feet. It could also be a way to show vulnerability or strength through the state of the characters' feet, like if a character has injured their foot, how it affects their journey and their role in the story.
One plot idea could be that the OC is a new earthbender in town. Toph senses their potential and decides to train them. Along the way, they face challenges like a group of earthbenders who don't want an outsider learning their ways. Another could be the OC is from a different nation but has an affinity for earthbending. Toph helps them hide this from others while also teaching them. Or perhaps the OC has a special ability related to earthbending that Toph is intrigued by and they go on a journey to discover the origin of this ability.
