I kind of hope that she does have some basis in reality, to be honest.
Assuming that this being is something like Sil from Species that is embedded within a transmission with the intention of bonding with human DNA to create a humanoid form that intends to f**k its way through humanity, reproduce and populate the Earth, and take over feels very much like a bio-weapon that the Engineers would attempt to use.
I'm not 100% sold on the design here, but the idea has a lot of potential (in the realm of comic books) and makes me wish that the art itself was better.
