7. Murmur

I wanted at least one super recent Flash villain on this list, and Murmur creeps me out, so on he goes.

Michael Amar was a creepy spindly serial killer who incriminated himself in a serious crime. As a result, he sewed his mouth shut. Seems like overkill to me, but I don’t want to be a Judge-y Jason about it. He took the name Murmur, in reference to his newfound inability to speak clearly. Presumably because “What? Speak up!!” and “Do you have marbles in your mouth or something?” didn’t make for great supervillain names.

Murmur is also immune to many toxins and poisons, which is a nice plus. Look, Ragdoll creeps me out, and Ragdoll didn’t SEW HIS FRIGGIN’ MOUTH SHUT. Jeezum Crow, that’s messed up. That’s messed up for realzies.

Unfortunately, Murmur doesn’t really come up that often. In fact, in all my research, I couldn’t find an instance of him being used after the end of the Geoff Johns run. Well, he showed up on Arrow, but that’s about it.
