Deathstorm is a name used by two villains who are dark reflections of the hero Firestorm. The first, introduced during Brightest Day, was the result of the fusion of a Black Lantern Ring and the Firestorm Matrix. The second, who first appeared during Forever Evil in the new 52, was the mirror universe version of Martin Stein, whose obsession with death consumed him. He has been a member of the Crime Syndicate.

Deathstorm was created by Geoff Johns and Peter Tomasi, first appearing in Brightest Day #10 (2010).
