She didn't take kindly to someone trying to get the drop on her. She didn't say anything, she simply reacted. She swiftly turned around, and at the same time, the sound waves from her headphones gathered in the palm of her hand. Before the creature could even say anything else, her fist smacked across his face, unleashing the destructive soundwaves at the same time. The soundwaves should have easily been powerful enough to send most people hurtling into a wall.
