Out of the Vortex #5 Dark Horse Comics (1993)

What's more formidable than a Destroyer? Two Destroyers! The alien from the Vortex takes his battle into space in this story of world-flattening violence -- violence so threatening that the U.S. government persuades Golden City's Grace to come to the desert to join forces with the alien! But will Vortex see Grace as an ally or an obstacle? And will the two of them together be a match for the Destroyers?
