Whisper is currently the leader of the Air Strike Patrol, a position he holds by being braver than Nightflight, smarter than Storm Cloud, and bolder than Tailwind. In fact, if he wasn't completely despicable, he'd probably make a good Autobot. Pity the position's taken.
Marvel comics continuity
Whisper and his patrolmates were the first Decepticon Micromasters to be created. Roadhandler was able to trick the Patrol into fleeing with the aid of the deactivated bomb.
When Roadhandler became an overnight wrestling sensation on Earth, Scorponok called in help to end the Autobot's growing public adulation, and an unknown Decepticon sent the Air Strike Patrol. Whisper got to threaten physical harm against small children to force Roadhandler to take a dive against Storm Cloud. 
Unknown to Scorponok, the patrol's secret employer was Megatron, who then sent the team on a mission to MacDill Air Force Base to capture the B-204 refueling plane. When the Autobots inevitably arrived, the team contacted Scorponok to tell him that they were under attack. After a brief confrontation with Optimus Prime and the arrival of Scorponok's Decepticons, the Air Strike Patrol fled, their mission completed.
They appear to have gone AWOL from the Decepticons after this, as Whisper was next seen as a private assassin with an open-ended contract to kill key Autobots. This in turn made Whisper a target of the Autobot Rescue Patrol, who damaged his wings and chased him into an Earthen forest. His patrolmates came to his aid, and the Rescue Patrol were called back by Optimus to stop the forest being destroyed.
Whisper led his team across the southern United States, finally attacking an oil refinery. This was the same oil refinery where Hector Dialonzo, a human with extraordinary powers, was working, and he single-handedly destroyed the Air Strike Patrol.
Marvel UK future timelines
In an alternate timeline, the Air Strike Patrol took Megatron's side in a Decepticon Civil War against factions led by Scorponok and Shockwave. They had a chance to kill a beaten Scorponok in 1991 but were stopped by the Autobots, as their battle was destroying a human city.
IDW comics continuity
Whisper was one of the legions of Dead Universe Micromasters who pursued Hardhead and Nightbeat on Gorlam Prime. He survived to confront Hardhead with the Jhiaxus-controlled Nightbeat in the planet's subterranean tunnels, but failed to prevent the Autobot from escaping into the Dead Universe.
