The upcoming solicitation for the return of Supergirl's comic in August sees it spin out of recent Brian Bendis storylines in Man of Steel, Action Comics and Superman. With a brand new costume to match (though not the one that you see on this cover, according to people at San Diego Comic-Con).

Mourning the loss of the Kryptonians wiped out by Rogol Zaar, Supergirl decides to play detective and sets off into deep space to learn more about the would-be usurper. Using whatever tech she can scrounge, Supergirl builds a star cruiser, and after intel from Green Lantern, she blasts off into the cosmos with Rogol Zaar's deadly axe to solve the mystery-along with a traveling companion you won't believe! In Shops: Aug 08, 2018
A travelling companion you won't believe? Well, if you look at Amanda Conner's variant cover for that issue, you may get an inkling…
And that's also the costume she wears in the comic as well…
