"Trust in your, Guardian Angel!"

The Guardian Angel is a character in "Dungeon." She seems to help Finn by healing him of his wounds and taking him to the Chamber of the Crystal Eye. However, the Guardian Angel soon transforms into a hideous monster and puts Finn into a cage, intending to eat him in a stew. She can remove scars, mend clothes, and heal wounds by touching that person with a lit finger. She also carries snacks.
