Superman: The Man of Tomorrow #15

Part of the 1999 "Last Rites" and "Day of Judgment" crossover events, this issue of Superman: The Man of Tomorrow presents a striking cover by Ryan Sook — a chained, battered Superman drifts before a glowing pod containing a small figure, while an eerie green-tinged alien face looms large in the background amid circuitry and dark, tentacled forms. The ominous imagery, paired with the story title "Heart of Hell," sets a brooding, otherworldly tone that feels distinctly different from Superman's usual fare. J. M. DeMatteis brings his thoughtful storytelling sensibility to the Man of Steel here, making this a compelling chapter in a genuinely ambitious corner of the 1999 DC universe.
