Origin

Whisper is a member of the Foreigner's Death Squad and has a mission with his teammate Pulse to eliminate Betty Brant who has discovered something big with international ramifications involving the Foreigner. Whisper and Pulse look for Betty at her apartment in Queens when a neighbor noticed the costume killers. The neighbor couldn't hear a sound due to Whisper's ability to absorb all the noise and sound within a certain proximity. Pulse blasts opens Betty's door and Whisper throws a blade into the neighbor's chest. The two assassins walk away because Betty wasn't home and the neighbor can't even hear himself  die. 
 
Peter Parker finds Betty the next day and the two have a talk at a local coffee shop. Betty tells Peter that she has gone deep undercover for an assignment given by Jonah Jameson and discovered big news regarding assassins and terrorism involving the Foreigner. Suddenly Peter can't hear a thing even when the windows at the cafe explode. Parker jumps behind a counter and out comes Spider Man. Betty and Spider Man take on Whisper and Pulse. Whisper jumps onto Spider Man's back with a blade in his hand while Pulse takes aim. Spider Man flips Whisper over and gets shot in the back by Pulse. Whisper is dead and Pulse tells the main frame that their mission has to be aborted because Spider Man has intercepted them. Pulse sits next to Whisper's body and executes the failsafe transmission data from his wrist. Spider Man and Betty barely escape when Pulse activates a self destruct sequence. 
 
Spider Man would follow Betty as she goes into the Foreigner's corporate building to kill him. They are confronted by two other members of the Death Squad called Swift and Warfare. Suddenly Spider Man can't hear a thing and sees Silence and Pulse appear nearby. The assassins go after Spider Man and Betty. Swift is killed by a blade thrown by Silence which was meant for the wall crawler. Silence is accidentally taken down by Pulse and then Spider Man takes down the other two members. The Foreigner appears on a television screen and informs Spider Man the origin of the Death Squad. The members were given their special abilities and high tech gear by the Foreigner's lab boys. Each Death Squad member also had brain implants to collect battle data which was transferred to the main computer. The information from past battles passes on to the next volunteer and the Foreigner had a long waiting list.    

Creation

Whisper was created by Howard Mackie and Alex Saviuk in 1992 and first appeared in Web of Spider-Man # 91.
 
Silence, Pulse and Swift-1 reappear sometime later and go after the Foreigner when he is branded a renegade. Foreigner is attacked outside his storehouse where several of his men were slaughtered inside. Foreigner lunges towards Silence but is caught in a bear hug. Foreigner grabs one of Silence's swords and kills him with it. Pulse and Swift-1 are defeated by the Foreigner due to Spider Man's interference.
