Powers and abilities Moonstone's powers derive from a Kree gravity stone (found on Earth's moon), charged with unknown energy and bonded to her nervous system.The Incredible Hulk #229 (November 1978)

She can use the stone to fly, and to become intangible to pass through solid objects (while intangible she is immune to some magic-based attacks).
