Adventures of the Jaguar #15

A towering, tentacled creature looms over the Jaguar, who crouches trapped inside a glowing spherical prison while a mysterious black pearl floats ominously nearby — the villain's speech bubble making the stakes unmistakably clear: "As long as I have the power of the Black Pearl, Jaguar, you are at my mercy!" John Giunta's cover pulls off a striking contrast between the hero's vivid red costume and the deep blue mass of the creature's coiling tentacles, all set against a burst of radiating golden light. This 1963 Archie Comics entry, featuring interior work by Robert Bernstein and John Rosenberger, makes a genuinely compelling case that the Jaguar faced some of his most imaginative threats in these later issues of the run.
