Toriel is the Captain of the Royal Guard. She's kind but with a stern side. She tries to protect the protagonist by commanding them to go to her home and only lets them continue when they show her that they're strong enough. This leads to a fight. She is in the role of Undyne.
Toriel's head resembles a goat, with droopy ears, short horns, and visible fangs. She has long eyelashes and eyes that are tinted a dark red. When not wearing armor, she wears a purple tank top with blue pants.
- Toriel, Asgore and Asriel resemble the luck dragon Falcor from the Neverending Story, as well the Mimiga from Cave Story, except that they resemble more anthropomorphic rabid/dog hybrids.
