Sub-Mariner #25

Namor stands defiant amid a scene of devastation on this 1970 Marvel cover, fist raised to the sky as fallen Atlanteans and scattered debris — including warning signs referencing DDT and chemical pollution — surround him at his feet. The cover's bold tagline, "Namor Battles the Human Race!", sets the stakes perfectly, with Namor's own words — "Surface-Men! You have destroyed my people… But I shall have my revenge!" — making his fury unmistakable. Cover pencils by Marie Severin and inks by Sal Buscema give the image a striking intensity, and Roy Thomas's story, "A World My Enemy!", promises an ecological rage that feels surprisingly resonant even for 1970.
