Red

Red is the protagonist of Transistor. She was a popular singer in the city of Cloudbank, but was then attacked by the Camerata in hopes of killing her. She was mysteriously teleported across the city in the middle of the assassination attempt, her life now saved. There she finds a powerful weapon, the Transistor, which she uses to fight the Process. The Process "took away [her] voice", likely meaning that she is now mute.
