~More Detail~
Shyanne Timberwolf was born into a family of five. An evil twin sister, a brother and parents. Shy was always a Daddy's girl, and her dad was a scientist. He worked alongside Gaster in a secret lab outside of humanity. Shy adored her father, and in secret, tagged along with her dad. One day he became distant, and told her he was going to experiment either her brother or Shy herself. Shy, (being Shy) sacrificed herself for about three years of Hell. The experiments turned Shy into a human-monster hybrid, thus gaining powers beyond her wildest dreams. Her Dad grew more distant as time passed and soon enough, started to brainwash Shy trying to turn her into a killing machine.
Before she was Brainwashed, she met Sans when they were kids and became close friends. Unfortunately, after the experiments began Shy's father didn't let them talk or interact.
About three months after being brainwashed and Gaster's (Shy saw Gaster as a fatherly figure, he had taught her how to heal instead of kill) attempts at reversing the brainwashing process, Shy had taken a walk Aboveground. She stumbled across a fight between Sans and her brother, Her brother (Eli) went for a killing blow but instead, Sans killed him. Shy watched in horror and fled whenever Sans saw her. Shy wears her brother's Jacket.
Not long after that the Lab exploded and killed her Father, and forcing the rest of the monsters back where they came from. Shy survived somehow, and  by the time she turned 15 she was living as a foster kid with Frisk and moving from home to home.
