The ability to
pass through physical matter.
User is able to move through objects and ignore most physical effects in their way, exact means how this is done vary between slipping partially into other dimensions, being able to make their own particles move between other particles, being non-physical being of energy, vibrating their molecules into a new quantum frequency, etc. Regardless the user is able to ignore most attacks, physical dangers and gravity.
: user merges into the object and emerges from the other side.
Amalgamation : user becomes a drawing on a wall or jump out of the second dimension.
Cartoon Physics : user reduces their density to allow them go through solid objects, or vice versa.
Density Manipulation : user shifts between dimensions to become intangible at various planes.
Dimension Shifting : user takes on the forms of certain elements (fire, water, energy, etc.) to allow all attacks to simply pass through them.
Elemental Intangibility : user's body, being an aggregate of tiny forms such as insects, allows attacks to pass right through them.
Living Hive : users molecules move fast enough that they become intangible
Molecular Oscillation : the user is untouchable.
Non-Corporeal Form : user folds the space around for similar effect.
Spatial Mimicry : user becomes untouchable, and pass through solids.
Spirit Physiology : user becomes simultaneously intangible and tangible.
Intangibility Cancellation makes this power useless.
Electricity can bridge the molecules in quantum phasing.
May need to hold their breath while inside solid objects.
Some materials/effects may be un-passable.
May be affected by energy or mystical effects.
May be limited in terms of effect (some may only be able to allow physical attacks to phase through their bodies, for example).
May only be able to phase certain parts of the body.
