Chillblaine

A cold-themed villain who slipped into DC's rogues-adjacent world with Flash Annual #5 in 1992, Chillblaine was brought to life by the creative team of Mark Waid, Craig Boldman, and Travis Charest during comics' Copper/Modern Age. With a catalog presence that puts him in the orbit of heavy hitters like Captain Cold, The Golden Glider, and the Trickster — all circling Wally West's Flash — he occupies that deliciously dangerous corner of Central City's underworld. Rare in appearances but collected in prestige editions like The Flash Omnibus by Geoff Johns, Chillblaine is exactly the kind of deep-cut discovery that makes digging through Flash back issues so rewarding.
