Intangibility (Phasing) is the ability to pass through solid objects by shifting one's density to one similar to a gas. One with this ability does not actually take on a gaseous form, but instead emits a psychic field that causes his molecules to separate, allowing movement seemingly through solid objects. Another theory about this ability is that the person can cause atoms to speed to a point where they are no longer a solid and are capable of moving through other objects. This ability can be achieved through another known as Imperceptibility.
