Killer Frost

Cold, calculating, and unmistakably DC, Killer Frost crashed into the Modern Age with Justice League of America #6 in 2013, brought to life by the powerhouse creative team of Geoff Johns, Jeff Lemire, and Doug Mahnke. Over a dozen years of appearances — spanning Titans, Justice League of America, and Future State: The Next Batman — she's carved out a place in some of DC's most ambitious corners, sharing pages with heavyweights like Batman, Cyborg, and Dick Grayson. With a catalog presence stretching from 2013 all the way to 2025, she's a Modern Age figure with genuine staying power, and for fans who love their DC mythology with an icy edge, she's well worth tracking down.
