In UNDERTALE, Toriel is the caretaker of the ruins and former queen of the underground. She is a kind loving monster who acts as a mother figure to the player after falling underground. She has kindness, but isn't afraid to be bold. She does not let any other monsters hurt you. In UNDERFELL, she is a lot more paranoid and schizophrenic. So you may hear her talking to herself occasionally. When UNDERFELL Toriel gets mad, boy can she get mad. Whatever you do, do NOT anger her. IN UNDERSWAP, she hears your presence and turns around, she is kind, but when she realizes that you're human, she immediately attacks you, not hesitating to do her duty. In OUTERTALE, she is identical to her classic counterpart personality wise, but she now controls a giant spaceship called the S.S. Toriellis (ss stands for "space ship") All the "ruins monsters" seen in ut live in this spaceship. (I guess you could say it's a MOTHER SHIP ;) )
