Frisk

Frisk is the gentle 7th child to have fallen into Mt. Ebott. Unlike her predessor Chara, who prefers to slaughter everything, frisk is a true pacifist, literally unable to hurt a living being according to her moral compass. When Frisk falls into Mt.Ebott, she gains the power to 'reset' the world, able to turn time back to when she fell down, erasing almost everyones memories in the process, except Sans and Flowey. Frisk's ture power, however, is the ability to befriend everyone she meets, even those who don't want to.
