Remember, this is an elemental of the void, sound, and the ether. It represents a slightly broad and vague, but mostly highly weird, concept of the fifth elemental state.

With the Nothingness lens applied, it's quite literally a screaming void - a being that's barely there, but which moves in the form of echoing noise. I imagine it as a slightly hokey '50s Hollywood special effect - a pulsing black blob, surrounded by glare and accompanied by a lot of primitive electronic sound effects. And yeah, it spends a lot of points on being insanely hard to hurt, even for PCs who think that they have special abilities that let them hurt anything.
