Body Transformation: Ashley Crawford is a mutant with the primary ability to alter the height and mass of her body by a tremendous degree. When she uses her powers, she gains an additional 15 inches in height and adds approximately 630 lbs of tissue to her frame.

Superhuman Strength: Transformed into her Big Bertha form, Ashley's physical strength is increased to superhuman levels. At her peak, she is able to lift at least 25 tons. Her great strength also extends into her legs, allowing her to leap great distances and heights.
