All three of the Wreckers survive during the event of the film. Comic adaptation revealed that they came to earth with Sideswipe, Jolt, Arcee, Chromia, Elita-1 and the Twins but had to stay at the secret Autobot launch facility at Cape Canaveral, partially because caring for the ship dominated their time.

Leadfoot - The Leader of the Wreckers. He turns into a Red #42 Juan Pablo Montoya NASCAR Target Chevrolet Impala. He speaks with a Cockney accent. He is Armed with laser guided missiles, jet boosters, 6 barrel 7.62mm minigun and 30 caliber machine guns.

He is hiding out in the plains of Namibia, Africa in exile, nursing wounds and taking care of Hatchlings. After Sentinel Prime betrayed the Autobots, Megatron and Starscream traveled to Washington D.C., where Megatron outlined his scheme to his second-in-command. Apparently, Sentinel was supposed to rendezvous with Megatron there on Earth, but the circumstances caused them both to be deactivated, and Sentinel was the only one who knew how to activate the space bridge. He blasted President Lincoln off his stone throne, and used the remains as a seat. In Chicago, after stating to Sentinel that this is the world he promised, Sentinel, feeling his partner was getting too chummy, violently reminded Megatron of his place. Sentinel did not work for Megatron, Megatron worked with Sentinel. Sentinel warned Megatron to remember the difference. While the Decepticons fought the Autobots, Megatron laid in an Alleyway until he was goaded by Carly that he is "Sentinel's bitch". Realising that she's right, Megatron saves Optimus from being Decapitated by Sentinel and wounding him in the process. He offers Optimus a truce, unaware that Prime uses this opportunity to murder him by shoving him to the ground, smashing his head with an energy axe, and tore it off his body, killing him once and for all. Optimus then used his nemesis' fusion shotgun to end Sentinel's life as well. Concept art of Megatron here

Under Soundwave's orders for Execution, he chooses that Que shall be executed first and pushed the Autobot scientist forward despite his pleas for mercy. After a Decepticon protoform delivered the first shot, Barricade killed Que by shooting him in the back and laughed derisively as his victim fell. After Soundwave's death, he met up with Shockwave and showed his anger by abusing & pushing the Protoforms, blaming them for Soundwave's death. He is killed by Nest while yelling at the Protoforms. He speaks with the same voice as Soundwave, this is most likely an error. Concept art of Barricade here.
Shockwave - The Decepticon military commander that turns into a Cybertronian Tank in the toyline, but does not transform in the film itself. Like his comic/tv counterpart he has one eye, is purple and has a gun in place of an arm. Though Shockwave did not appear in the last movie, he is briefly seen on the front page of a newspaper that is hanging from the pipe in the scene where Devastator is trying to suck up the twins. At some point during 2009, Shockwave was caught on film and the event was written up for a newspaper article. A newspaper page with the headline "Mysterious Robot Spotted" was discarded in Egypt, where it was sucked up by a rampaging Devastator. Concept art of Shockwave here.
Driller - A subterranean tentacle-beast lifeform native to Cybertron and some of the single most dangerous creatures on or under the planet's surface. He serves as Shockwave's pet.

Hatchet - A Dread with an animal-like robot mode. Hatchet was targeted by the Autobot Dino, who embedded his anchored blades into the Decepticon's back, and corralled Hatchet into the firing line of Bumblebee and Sideswipe. After Hatchet was pounded with Autobot ordnance, Dino tossed the Decepticon into the oncoming side of the highway, where he slammed into a passing car and was destroyed. Concept art of Hatchet here.
Crowbar - The Dread who is killed by Ironhide after Sideswipe tossed the Autobot veteran his discarded blaster, which he used to shoot the Decepticon in the face as Crowbar leaped to attack. Concept art of Crowbar here.

Heturns into Russian Military Launcher. During the invasion of Chicago, he participated in the initial strike and contributed to the mayhem. During the Autobot's attack on this Decepticon stronghold, he was one of the many Decepticons who fired upon the retreating Autobots. When the tide began to turn in the Autobot's favor, however, the behemoth met his end as he tried to hold a bridge. The Wreckers piled onto him, shooting him in the head multiple times until he fell to the ground dead. Concept art of this Decepticon here.
Unknown Brawl Clone - A Decepticon whose design is similar to Brawl from the first movie, the only difference is that his colour scheme is brown. Spotted in the trailer participating in the Chicago battle. It is possible he could be based on Deep Desert Brawl from the toyline. He has the same weapons and armory of Brawl. Seeing how he resembles him, it is possible his alternate mode is a M1 Abrams Battle Tank.
Unknown Long Haul Clone - A Decepticon that looks exactly like Long Haul spotted in the trailer participating in the Chicage battle. But unlike real Long Haul, this one turns into a WM garbage truck. Artwork of this Decepticon here.
