Michael Amar, known by his street name Murmur, is a criminal who was wrongly imprisoned in Iron Heights Prison for giving a false confession. He later was freed from prison by Damien Darhk and allied with his organization H.I.V.E.
Before Iron Heights
Release from Iron Heights Prison and Criminal Activity
In early 2015, Amar was released from prison. Since his mouth was sewn shut, he is now known as Murmur. He and his gang set out to rob diamond bullets which can go through police armour. The Arrow, Arsenal, and Black Canary arrive and try to stop Murmur and his gang, but they get away with most of the diamond bullets. Later, Murmur and his gang storm the police station where the diamond bullets come to their advantage by killing police by going through their armour. Murmur confronts Captain Quentin Lance and starts to strangle him, but The Arrow shoots him in the shoulder. Meanwhile, Arsenal, Black Canary, Nyssa al Ghul, and the rest of the police defeat Murmur's gang. Murmur manages to escape the station and kills an incoming police officer. He then removes the arrow shot in his shoulder and starts to flee the scene of the crime. However, The Arrow intercepts him and starts to fight Murmur. Murmur attempts to strangle The Arrow, but is knocked out by him moments later. He is then sent back to Iron Heights Prison. Ra's al Ghul later kills 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.
