Time Wars
In their first appearance (UK #199-205), they were teamed up with the Wreckers (as well as Inferno) to take down Galvatron - and had orders to kill any Wreckers left standing. The team was led by Carnivac and consisted mainly of older toy characters that had never been used before, with the exception of Catilla, a newly-released Pretender Autobot introduced as a Decepticon, and Flywheels, who had recently appeared in the City Of Fear storyline.
By the end of the Time Wars, only Carnivac and Catilla were left alive (though Flywheels was never killed on-panel and may have also survived). Finding themselves isolated from the other Decepticons and having found a high level of comraderie with the surviving Wreckers, Carnivac & Catilla went rogue and joined them in a new group called the Survivors.
Springer and Broadside later formed the Survivors with Inferno, Skids and Mayhem left-overs Carnivac and Catill
