Void was spawned from a black hole, and ejected into outer space, without a face, without a form, and without purpose. This mass of antimatter (or void) gained sentience and started eating anything to keep itself alive; as if it didn't it would dissipate and die. This mass eventually found Earth, and considered eating it as well, but after discovering and seeing all the life it held on it (something all previous planets lacked) she decided to stick around. In an attempt to blend in with humans, she wears a rubber skin suit, and it helps her keep a form too.

Ironically, she's quite antisocial, and dislikes going outside for extended periods of time, but like anyone, still often socializes with friends.

Her friends Eve and bow is by comparison a bit more social, especially Bow, and they're usually the ones who get her to go outside.
