Who is that on the cover to the Prologue?

[Somebody]

Ronan, Star-Lord, Nova, Wraith, Moondragon & Phylasar are all recognisable, of course. I'm referring to the head in the bottom-left (well, that and the little Starbug flying at Phyla). We're a couple of months in now, and I don't see who it is.

[Jack]

Super-Skrull. Look closely and you can see the wrinkly chin and the pointy ears.
