Toriel

Toriel fell down during the early stages of The Starvation outbreak. When Flowey began his onslaught, Toriel sacrificed her soul to eject Frisk from the Underground, so that she could find help. Upon passing through the Barrier, Toriels' sould eroded, being unable to survive in her body any longer. The last thing Toriel ever saw, was the spectacular sunset descending over Ebott City.
