They're all repaints/retools squeezed out of the Stunticons of the line. We also got a smokescreen, hound (from swindle), ironhide (from "offroad", wildrider's 4x4 replacement), and sunstreaker (from breakdown).
Sky Lynx was also done as a combiner torso, and the line also gave us a superion, menasor, devastator, defensor, bruticus, and computron. They all have the "scramble city" feature with the limb members except for devastator.
