Mecha only appears in flashback.
Eric Shanower is erroneously credited as cover artist, however Arthur Adams' signature is clearly on the cover and a correction is noted in the letters page of the next issue.
*Out of the Vortex: The Seventh is full of suprises -- for the Vortex alien, for Mecha, and even for the last of the Destroyers, who turns out to be the most formidable of his brothers and the least vulnerable. Golden City's Mecha "powers up" to all-new levels, with the alien's help, but even the two of them together are no match for the seventh Destroyer. His back against the wall, his laboratory overrun by the military, the alien plays his last, desperate trump card in a game with worlds at stake! *Source: darkhorse.com
