Toriel

Toriel is a a guardian of the Ruins, Asgore's ex-wife, and a major character of the 2015 game, Undertale. She is a driving force behind many of the game's events.

Appearance
Her appearance is that of an anthropomorphic goat. She wears a large, slate-blue dress or robe that displays the Delta Rune on her chest and is occasionally seen with her reading glasses. Her eyes appear to have a slight red tint to them.

Personality
Toriel is a very kind, motherly monster who genuinely cares for the protagonist and their well-being. While ultimately a benign figure, she does have a harder side to her personality, as seen by her refusal to allow Frisk to leave the Ruins and by her cold treatment of Asgore. In addition, she has something of a mischievous streak, evidenced by her interactions with Sans.

Toriel enjoys cooking. Many of her recipes use snails as a primary ingredient, as her favorite food is snail pie. She is also able to bake other things quite well though, as shown when she bakes a cinnamon-butterscotch pie for her and the player (excluding Hard Mode, in which she makes a snail pie in due to lack of ingredients.).

She has always wanted to be a teacher. By the time the protagonist reaches her house, she states that she has already prepared a curriculum for their education. This is also illustrated in the game's credits, as she is shown standing outside a school, and in certain Neutral Endings, in which she starts a school.

Trivia

 * Some players nicknamed her "Goat Mom" due to her motherly nature.
 * Toriel is based on Toby Fox's mother.
