Secondly, create a unique plot. It could be centered around a mystery in the Underground that only the combination of Toriel's knowledge and the OC human's unique skills can solve. This gives a reason for them to interact and work together throughout the fanfiction.
First, understand the personalities of both Toriel and your OC human well. Toriel is motherly and kind, so your OC's reactions to her should be appropriate. For example, if your OC is a tough - guy type, their initial resistance to Toriel's mothering could create an interesting dynamic.
Finally, don't forget about the emotional aspect. Develop the relationship between Toriel and the OC human gradually. Show how they grow to care for each other. Maybe the OC human starts to see Toriel as a mother figure, or Toriel starts to see the OC as a special friend. This emotional connection will make the fanfiction more engaging and heartfelt. There should be moments of conflict, too, to add depth to the story, like when their views on how to deal with a certain situation in the Underground differ.
One idea could be that the OC human is a lost traveler in the Underground. Toriel discovers the human and decides to take them under her wing. The fanfiction could focus on the relationship that develops between them as Toriel teaches the human about the Underground's ways and they share heart - to - heart conversations.
First, you need to develop your OC well. Decide on their personality, appearance, and backstory. For example, if your OC is a kind - hearted mage, think about how they would interact with Toriel. Then, consider the setting. Will it be in the Underground? Or maybe a different AU (Alternate Universe). Next, plan out the plot. It could start with their first meeting, like perhaps your OC gets lost in the Ruins and Toriel finds them. Keep in mind Toriel's character traits such as her motherly nature and her love for puzzles.
To write a great Undertale Underfell Sans x Fell Toriel fanfiction, you need to research the Underfell universe thoroughly. Know the rules, the power dynamics, and the overall atmosphere. When it comes to their relationship, start with small moments. Maybe Fell Sans brings Fell Toriel a small gift, like a flower from the dangerous parts of the Underground. This simple act can start to break the ice between them. As for the writing style, use vivid descriptions to bring the Underfell setting to life. Describe the dark corridors and the menacing monsters in the background as their relationship unfolds.
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.
The plot is also crucial. It could explore the unique relationship between a human and a monster in the Undertale universe. Maybe it could involve the human male helping Toriel with some issues in the Underground, or them going on an adventure together. This kind of plot can add depth and interest to the story. And don't forget about the writing style. A vivid and engaging writing style can really bring the story to life, making the reader feel like they are part of the Undertale world.

They can also have shared goals, like trying to improve the situation in the Underground or finding a way to coexist peacefully.
