Star Trek #46

This 1977 Whitman entry in the long-running Star Trek comics series centers on a genuinely unsettling premise: Spock lies prostrate, his head aglow with an eerie light, while a crewmate leans over him and a small alien figure tends to his side — all beneath the looming barrel of some massive alien device. Kirk stands watchfully to the right as two green-skinned aliens operate the machinery above, and the cover copy makes the stakes plain: "Spock's swollen brain grapples with insanity to save a planet's culture." Writer Arnold Drake and artist/inker Al McWilliams deliver a tense, cerebral setup in "Mr. Oracle" that puts the Enterprise's most logical mind in a very illogical kind of peril.
