Astonishing Tales #18

In "Gog Cometh!", Ka-Zar races against time to reclaim the super-soldier serum from the cunning Gemini, only to see Gog vanish with his alien powers while Gemini and Lord Plunder slip away. When SHIELD moves to destroy Professor Victor Conrad’s lab—and the serum’s original formula—Conrad seizes the chance to take the formula himself, setting off a transformation that will reshape his destiny. Written by Mike Friedrich and illustrated by Dan Adkins, with inks by Frank Chiaramonte, colors by Stan Goldberg, and letters by Artie Simek, this 1973 Marvel classic features a cover by John Romita, pencils and inks.
