Superman: The Kryptonite Spectrum (2025) #5

What’s truly at the end of the rainbow? We can’t be certain, but we’re pretty sure it ain’t a pot of gold! Up to now it’s been a peculiar, polychromatic pilgrimage for Superman: he’s lost track of time under the influence of Purple Kryptonite, grown to skyscraper size via Cobalt K, revisited his adolescence by way of Speckled K, and traveled to the fifth dimension using a “key” carved of Rainbow Rock. Now, in this final issue, the chickens have come home to roost—and so, too, has Kal-El. Back in Metropolis, the Man of Tomorrow must stand face-to-face with the Man of Today…and decide for himself, finally, whether Lex is right: Does home hurt too much?
