DC Comics Presents #4

The cover of this December 1978 DC Comics Presents says it all: Superman strains against a massive burst of energy while the Metal Men — several of them scattered and battered across the body of the enormous chemical creature Chemo — struggle alongside him in what looks like a genuinely desperate situation. José Luis García-López's cover art crackles with urgency, from Superman's cape whipping dramatically behind him to the toxic green splashes radiating off Chemo's hulking form. With Len Wein scripting and the ominous cover copy warning that failure means nobody survives, this team-up between the Man of Steel and the Men of Metal has real stakes baked right into the premise.
