What are some interesting undertale human adult fanfiction stories?

Here are some plot ideas. First, the adult human could be a scientist. They meet Toriel and start to analyze the magic in the Underground. As they collaborate, they grow closer. Second, the human might be a storyteller. They tell Toriel tales of great heroes and adventures from the surface. Toriel is so captivated that she wants to be part of those stories with the human. Third, the human has a troubled past. Toriel, with her motherly nature, helps the human heal. Through this process, their relationship blossoms. In all these ideas, their relationship can develop in a non - sexual, deep and meaningful way, exploring themes of friendship, understanding and hope.

A possible idea is to have the human character start a club or organization in the Underground. It could be a book club, a gardening club, or a club focused on exploring the history of both the human and monster worlds. This would allow for interactions between the human and different monsters, and would be a fun and family - friendly fanfiction concept.

One interesting aspect could be the different interpretations of the six human souls. Maybe some fanfictions focus on their backstories before they ended up in the Underground. For example, a story might explore how they got their unique traits that are associated with their souls.

One interesting idea could be exploring new character backstories. For example, delving deeper into the lives of the new human characters before they arrived in the Underground. Maybe they had unique families or past experiences that shaped their personalities in the fanfiction world.

One interesting plot could be the new human having unique powers that change the dynamic with the monsters in the Underground. For example, they might be able to communicate with certain monsters in a way that no other human has before, leading to new alliances and story developments.

One interesting concept could be the exploration of the unique powers and personalities of each of the six human souls. They might be depicted in ways that expand on what we know from the original Undertale game, like showing how their traits interact with the Underground world in new and unexpected ways.

One interesting story could be about the characters' reactions to different timelines. For example, Sans might react in a unique way when faced with a timeline where everyone is overly aggressive. Another could be the reactions of the monsters to human technology that they've never seen before, like a smartphone. And there could also be stories about how the characters react to fan - made scenarios, such as a 'what if' situation where Asriel didn't turn into Flowey.
