Erin is a 20-year-old woman with brown hair and hazel eyes. She is about 170 cm tall and weighs 59 kg; she has an athletic build and rather muscular arms. She is known by being the only survivor of the 1974 Texas Chainsaw Massacre. Just like everyone else in the Shadow Universe, that was or not resurrected, she is apparently immortal in the sense that she doesn't age or get old. While in the juvenile hall, Erin learned some larcenous skills including the ability to open locks without the proper keys and hot-wiring cars. Erin is clearly a strong and athletic young woman, in great physical shape and possessing athlete-level stamina, as she is able to outrun and evade Leatherface. Her mental fortitude is also immense.
