Elasticity is the ability to stretch, deform, expand and contract one's body.
- Piper is the only character that has demonstrated this ability; she demonstrated it in a dream.
In a dream, Piper demonstrated her ability to abnormally bend and stretch one of her legs to reach and undo the latch on a lock. She also contracted herself to fit through a small window and expanded to normal size once she was through the window. Thus far, Piper has only used her ability with concentration and for short periods of time, and each instance has been within a dream. She has never demonstrated the power in her waking life.
