The Wreckers are the elite. They are the Autobot equivilent of the Decepticon Seekers, or Straxus Brigade. When you have a lost cause, with no possible chance of victory, you call in the Wreckers. They're job is to basically turn up and shoot anything resembling a Decepticon. With their starship, Omega Supreme, the Wreckers are ready for anything. Under the command of Ultra Magnus, the Wreckers never failed. Until Praxus-9. Optimus says Magnus still sees it during recharge. The bodies of his friends littering the prisons asteroid. And the final, bloody messy end. there were more Autobots left than Decepticons at the end. But nobody won. Not really.
