Michael Amar, known by his street name Murmur, is a criminal who was wrongly imprisoned in Iron Heights Prison for giving a false confession. After being released, he became a professional thief and enemy of Team Arrow. Later after being freed from prison by Damien Darhk, he briefly allied with the organization H.I.V.E..
Before Iron Heights
Release from Iron Heights Prison and criminal activities
In early 2015, Amar was released from prison. Since his mouth was sewn shut, he received the nickname "Murmur." He and his gang set out to rob diamond bullets which could penetrate police armor. The Arrow, Arsenal, and Black Canary arrived and tried to stop Murmur and his gang, but they got away with most of the diamond bullets. Later, Murmur and his gang stormed the police station where the diamond bullets came to their advantage. Murmur confronted Captain Quentin Lance and started to strangle him, but The Arrow shot him in the shoulder. Meanwhile, Arsenal, Black Canary, Nyssa al Ghul, and the rest of the police defeated Murmur's gang. Murmur managed to escape the station and killed an incoming police officer. He then removed the arrow shot in his shoulder and started to flee the scene of the crime. However, The Arrow intercepted and fought him. Murmur attempted to strangle The Arrow, but was knocked out by him moments later. He was then sent back to Iron Heights Prison. Ra's al Ghul later killed all but one of Murmur's surviving gangsters.
Allying with H.I.V.E.
In Iron Heights, Murmur and two new members of his gang assaulted the powerless Damien Darhk when he first arrived. Later, after Darhk made contact with Murmur's grandmother and threatened to kill her if Murmur didn't help him, Murmur turned on his gang members and stabbed them to death with a shiv.
On Damien's orders, Murmur passed out books with shivs within them to many inmates of Iron Heights. Once Malcolm Merlyn freed Damien, Murmur and the other inmates broke out with the shivs and killed many guards, before escaping with Damien and Merlyn after Damien killed Laurel.
Murmur became Damien's right-hand man upon his return to H.I.V.E., and witnessed his killing of Milo Armitage and Phaedra Nixon. Damien later sent him and Danny Brickwell to kill Noah Kuttler in order to prevent him from stopping Genesis, but Kuttler was saved by Team Arrow. Damien sent Brickwell and Amar to battle Team Arrow a second time, but the two were defeated again. It is unknown what became of Amar after the battle but it can be assumed he was taken into custody along with Brickwell.

Behind the scenes
- In the DC comics, Murmur is traditionally an enemy of The Flash. A doctor-turned-serial-killer, suffering from schizophrenia and going crazy due to the voices in his head, he went on his killing spree and involuntarily confesses his crimes. He cut out his own tongue and sews his mouth after his arrest, to prevent him incriminating himself again in the future. He also has a uniquely toxic blood type that is immune for him to euthanization and allows synthesizing of a virus out of it.
