Cemetery Wind

Cemetery Wind is a CIA black ops division created by Harold Attinger (the main antagonist) in Transformers: Age of Extinction and they are the main group of antagonists in the movie. They were tasked to eliminate any remaining Decepticons on Earth, and were ordered by the President to leave the Autobots alone. But Attinger took advantage of his authority and made a deal with Lockdown, wiping out all Transformers and deliver their remains to KSI, then KSI melting them down for materials to build their artificial, remote-controlled Transformers, make them a better world, and killing any humans who discovered their operation. But with the deaths of both Attinger and his right-hand man James Savoy, Cemetery Wind is disbanded by the U.S. government and labeled as a terrorist organization. Collectively, they serve as the septenary antagonists of the film.

Trivia

 * Though not a medium, it may be possible that Cemetery Wind may have also killed Sam Witwicky, his friends and family & most of the members of N.E.S.T. due to that Attinger have ordered to kill anyone who discovers their plans of killing Transformers as Bumblebee came back without any human companions.
 * Known Transformers labeled on Attinger's cards are Sentinel Prime, Ironhide, Que/Wheeljack, Arcee (misspelled as "Acree"), Starscream, Shockwave & Loader. It is also presumed Cemetery Wind may have killed the surviving Transformers of the previous film off-screen such as Wheelie (if one doesn't consider his death in the previous film), Sideswipe, Chromia (if one doesn't consider her death in the second film), Dino/Mirage, Topspin, Roadbuster & Igor.
