10 Deadliest Enemies The Flash Ever Faced
6. Murmur
An enemy from Wally West's Rogues' Gallery, Murmur is one of the most lethal Flash foes - despite him not possessing any superpowers.
Introduced in The Flash: Iron Heights from 2001, Doctor Michael Amar was once a well-respected surgeon before he went insane and became a serial killer. Muttering to himself uncontrollably, he hunted down and picked off his prey whilst he lived his double-life as a surgeon.
After dropping bodies left, right, and centre, Murmur was finally caught by Keystone City's police force and sent to Iron Heights prison - where he later escaped and joined the new Rogues' Gallery.
Cutting off his own tongue and sewing up his mouth in an attempt to quiet his murmuring, this deadly serial killer was an unpredictable threat for the Fastest Man Alive.
More obscure than some of the other entries on this list, this deadly, knife-wielding madman shouldn't be underestimated.
