The power to
become an element to simulate intangibility. Combination of Elemental Mimicry and Intangibility.
The user can transform into different elements (fire, water, air, etc.) to achieve a form of intangibility, allowing attacks to either pass right through their elemental bodies or be harmlessly absorbed into their bodies, depending on the user's element. This also can allow them to phase through solid objects that do not obstruct the element the user mimics.
Obstructions or materials that affect the imitated element will still affect the user.
Users of Intangibility Cancellation can still deal damage to the user.
