Dimension Shifting

Dimension Shifting allows the user, by using Psychokinesis, to alter and manipulate the physical dimensions of themselves, objects, and even other persons depending on the skill level of the user. 0-D, 1-D, 2-D, 3-D, and 4-D are the dimensions any user able to move through.

Dimension Zero
The user becomes a spec of matter of infinitesimal size. If the user still possesses any weight at all then they are invulnerable, and without some sort of microscopic vision, they are completely invisible and even so may still be indistinguishable from any other subatomic particle.

First Dimension
The user becomes a thin, nearly invisible line. Users could be very flexible, and easily avoid attacks. The user can fit through absolutely any crack or hole no matter how small and may have supernaturally dense tissue like it's succeeding dimension.

Second Dimension
The user becomes completely flat. User's sides are incredibly sharp and can cause severe "paper-cuts". Users may also be able to be folded for storage, or into "origami-esque" forms. The user may be light enough to float in the air. Subjects can fit through virtually any space, and because of an extreme lack of size, may have supernaturally dense tissue despite their lack of weight.

Third Dimension
The dimension where all users begin, this dimension grants the the user no special abilities or modifications.

Fourth Dimension
The user has an extra physical dimension to move through. As a result, they cannot be bound by three dimensional objects just as a 3-D being cannot be bound by a 2-D object. The user is undetectable by any means when not within our three dimensional space, may have extremely increased lung capacity and can alter how three dimensional beings perceive them.
