Murmur

Murmur is a disturbed serial killer and member of the Flash's rogues' gallery, introduced in 2002. A physician who murdered his patients, he cut out his own tongue and sewed his lips shut to prevent himself from confessing his crimes.

Few villains crawl under your skin quite like Murmur, who slithered into the DC Universe through the pages of Flash #183 in 2002, courtesy of the legendary creative team of Geoff Johns and Scott Kolins. A Modern Age creation born into one of comics' most electrifying rogues' galleries, this unsettling figure shares panel space with the likes of The Flash, Trickster, and Weather Wizard — dangerous company that speaks volumes about where Murmur sits in the DC pecking order. Across nearly two decades of appearances, this character has carved out a genuinely creepy niche among Central City's most memorable threats, the kind of figure that sticks with readers long after the issue is closed.
