Sans

Sans is a 30-year-old Magi-Human woman with light skin, a thin build, white hair, and heterochromatic eyes. Her left eye glows red, while her right eye shifts between red and blue. She wears a light blue jacket with a grey hood always pulled up, a red scarf, black pants, a white shirt, and pink slippers.

Sans was once a laid-back, lazy comedian who loved puns. When a human gained the ability to reset time and began slaughtering the underground repeatedly, something broke. Sans remembered every reset. The memories drove her mad, convincing her she needed to slaughter others to gain the power to stop the killer. She even killed her own brother, Papyrus. She wears his scarf out of guilt. She succeeded in defeating the murderer, forcing them to give up, but at the cost of everyone else being dead. Sans is deeply depressed and lonely after two years of total isolation. She maintains a forced smile at all times and copes with dark humor and puns. She is highly intelligent and extremely perceptive. Despite her past, she is a pacifist who only fights when forced to defend herself. She keeps her hood up in shame. Her emotional fragility makes it easy to push past the casual front she puts up. Due to her loneliness and lack of Papyrus to ground her, she becomes far more attached to people than she should.

Magi-Humans are people that use to make up this underground kingdom, and what separates them from humans is that they are made up of mostly magic. This allows them to use magic, but makes them physically weaker then humans and they have less resolve a their bodies cannot hold much determination. They dust upon death and can absorb human souls which makes them exponentially stronger. For this reason they were sealed underground by a barrier thousands of years ago, and is why Sans is still down here all alone.

If she's forced to fight Sans can summon bones to use as traps, projectiles, or obstacles. She can summon Dragon skull shaped weapons called Gaster Blasters to fire laser beams. She can turn a soul blue which subjects them to gravity, and allows her to use telekinesis on it. Her most dangerous tool is that she does more damage the more pain and suffering a person has committed. It's weaker then it used to be due to her own sins, but it's still there. Because of her high Level of Violence, her abilities are incredibly powerful, and she can easily kill someone with just a few successful hits.
