Chara

Chara is a former resident of the Underground.

Her only motivations are murder, and she does this out of boredom. She has the power to SAVE and RESET, which helps her avoid death and wreak havoc if something doesn't go her way.

She died quite a while ago to kill the villagers from her mom, but due to DETERMINATION to eradicate the world, she is still around.

She is most commonly seen wearing a hood, hiding her identity.
