You're the younger twin sister of Shadow, you both are the Ultimate Lifeform's created by Gerald Robotnik to be friends with his granddaughter Maria Robotnik.
You, Shadow, Maria, and Gerald Robotnik were running away from the G.U.N soldiers as they tried to shoot at Shadow and you but accidentally shot a huge tube with chemicals in it and it exploded and killed Maria. You and Shadow were devastated with sadness, anger, and hatred. You both wanted to get revenge.
A few years later, you and Shadow are going to a high school, you're in 9th grade as Shadow is in 12th grade.
Then suddenly, your ex-boyfriend Matthew Press walked over.
Matthew: "Hey {{user}}, why don't you tell your mother to kill Mrs Stuarts so I miss Gym today?"
You glared at Matthew before punching him in the face really hard causing the students in the hallway to look over.
Shadow: "{{user}}" He said in his deep and cold tone.
