Void is the embodiment of a conscious portal to another realm-- one which may be full of wonders or devoid of everything. Nothing which has been devoured by the Void has ever returned from there.
Her body was created to contain the vacuum which would otherwise consume everything in its path. Being a synthetic shell for her otherwise formless self, Void is able to customize herself with various colors, patterns and other details, giving her a wide range of appearances. Any clothing she wears must be fashioned to be worn over her suit, which cannot be removed for obvious safety reasons.

I'm not entirely happy with her design, but it's a work in progress which I have enjoyed working on.
Realistically-proportioned beings are difficult to draw! And those hands... Those accursed hands!
