User is made up of or can transform their body completely into ectoplasm. Users transformed form can be either anatomically identical to their normal form, aside of being made of ectoplasm, in which case it contains all to organs and is somewhat vulnerable to attacks. Alternately user can transform into homogenous matter, without any part of their form being more important than the other. Because of its unstable, esoteric properties, ectoplasm reacts to normal matter/energy in unusual and useful ways, including being able to ignore most of them.
