Toriel

Toriel was the former Queen of Monsterkind. She retreated to the Ruins after her children's deaths and became its caretaker, pledging to look after any humans that fell into the Underground.

After years of residing in the Ruins, another human fell into Toriel's hands. She quickly noticed just how different this human was, but could never quite put her finger on it. Little to her knowledge, the human's determination granted them the power to SAVE and RESET, an ability that they eventually, after many timelines, used to free the Underground once and for all.

Frisk's Arrival
During a timeline where Frisk decided to stay in the Ruins, Toriel read them a story in their bedroom.

Personality
Toriel was known to love both reading and telling stories, and was always willing to share them with others, especially her children. One of her hobby's was bug-hunting, and her favorite bug-hunting spot was, ironically, Chara's grave.

Appearance
Toriel was an anthropomorphic Nubian Goat, so she naturally had a long snout, droopy ears, short horns, and large paws at the ends of her limbs. Her fur was white and pristine, her eyelashes were long, and her eyebrows were neatly trimmed. Along with her dark, glittering red eyes, she regularly wore a kind expression on her face, showing off a pair of fangs.

Toriel's attire was a purple robe that ended at her ankles, with white sleeves and trim. The Delta Rune was displayed on her chest in white and indigo, and the collar of the dress went up to her neck.

Chara Dreemurr
Toriel taught Chara many things while they were in her care. It seemed that Chara may have assimilated a few things, such as their habit of unconscious storytelling.

Frisk
Toriel had a habit of patting Frisk's head, mainly when she was proud of them.

Like all of her other children, Toriel enjoyed teaching, sharing fun facts, and reading to Frisk. She also loved bug-hunting with them.
