Vortex Grinder
Humans say you are what you eat. Devastator takes this to the extreme with his Vortex Grinder.<ref>Devastator's Battle Bio at Hasbro.com</ref> Using an artificial black hole, Devastator can swallow in nearby objects. Once they reach his plasma core, they are broken down by the extreme temperatures and turned into molten stew. All useful materials are absorbed and the rest are expelled from his back.<ref>Revenge of the Fallen: The Movie Universe</ref>
This happens to include living beings, be they organic or Autobot.
Fiction
Revenge of the Fallen film
Once the Constructicons had finished combining in a quarry near the Great Pyramid of Giza, Devastator activated his Vortex Grinder and began sucking in all nearby objects, including a few cars, some livestock, and a few hapless bystanders. Seymour Simmons was nearly sucked in, but was saved by Leo Spitz. The Autobot Mudflap was less fortunate, and was pulled into the maw. This caused Devastator to deactivate the Vortex Grinder long enough to for the Humans and surviving Autobot Skids to make a mad dash under Devastator, as it was the only safe place. They also got a little extra time when Mudflap burst out of Devastator's head, alive and well.
Once had successfully managed to reach the top of the Great Pyramid, Devastator again activated his Vortex Grinder and began absorbing the rocks that surrounded the solar harvester that the Decepticons were trying to activate. Devastator had resorted to his fists by the time the U.S.S. Kidd fired her experimental railgun, destroying Devastator. Revenge of the Fallen
