Density Shifting

From Activating Evolution

Density Shifting is the ability to use psionic power to alter one’s own density concentration. This ability can be used to become extremely dense, so the body is nearly impenetrable and hits are powerfully concussive, or to become intangible, so as to evade concussive blows altogether. Usually this ability only allows one type of density shifting or the other; however, it is not uncommon for the user to become dense or intangible as desired. Sometimes this ability could even be used to change the compactness of other things as well (called Density Manipulation). This ability can allow Superhuman Endurance (if the user compacts himself) or Levity (if the user disperses oneself).

[edit] Variations:

Size-Altering Density Shifting

• Size-Altering Density Shifting, also called Size-Dilating Density Shifting is a version of Density Shifting in which the compaction/expansion of the user’s molecules results in a change in size as well as a change in density. If the user compacts his molecules so that he can become denser, he will also become smaller (but will retain weight, strength and durability as if he were normal size). If the user loosens his molecules to become less dense, he will become larger (psionic energy will fill in the gaps where the outspread molecules leave empty spaces, so that the user is tangible, and still has a definite shape; he still retains weight and strength).
