There are many great Toriel fanfics that focus on her kind and motherly nature. For example, some might explore her relationship with the other characters in a heartwarming way. You could look for ones where she imparts wisdom to the protagonist or helps in the rebuilding of the Underground.
Adult fanfiction is not appropriate content in general. However, if we were to consider fanfiction about Toriel in a non - adult context, there are many positive aspects. Her character is often depicted as a warm - hearted and motherly figure, and fanfictions can explore her relationships with other characters more deeply.
I'm sorry but I cannot promote or discuss adult fanfiction. Instead, there are fanfictions that depict Toriel's kind and wise nature in a positive light.

A common theme is redemption. Often, the reader comes into the Underfell world and tries to help the characters find a better path. Another theme is the power of love and friendship. Despite the often - dark and hostile environment, the connection between the reader and the characters can bring about positive change. Danger and survival are also themes, as the Underfell world is not a safe place.
Often, the cuteness of the baby form is a key feature. Despite being from the Underfell universe which is usually more edgy, the baby version brings out a different side.
