The Overkill Device, or Izbutomiut in the Ossetian language, was a weapon built by South Ossetian separatists that utilized sonic vibrations and was capable of activating any weapon from a gun, to a missile on a plane, to a nuclear missile in its silo. The English name was a direct translation of the Georgian original.
S.H.I.E.L.D. learned of the existence of the Overkill Device when Agent Phil Coulson's team extracted Agent Shaw from his undercover assignment in Siberia. The original name in Ossetian was Izbutomiut, according to Agent Hand.
With the intelligence provided by Shaw, S.H.I.E.L.D. learned that the South Ossetian separatists were planning on utilizing the Overkill Device in an attempt to declare their independence from Russia and Georgia.
S.H.I.E.L.D. planned an assault on the separatists, but needed a two-man team to go in ahead and deactivate the Overkill Device, lest it be used to against the assault teams.
To this end, Agent Victoria Hand sent in Agents Grant Ward and Leo Fitz to neutralize the weapon. Ward and Fitz were successful in their efforts to deactivate the weapon, allowing for the S.H.I.E.L.D. strike force to successfully neutralize the separatists.
Turn, Turn, Turn Edit
S.H.I.E.L.D. agents use smaller versions of the device to disable the Bus' guns.
Heavy is the HeadEdit
Agent Coulson used a miniaturized version of the Overkill Device, built and modified by Agents Fitz and Mack, to neutralize Carl Creel's special abilities. It is unknown whether or not it actually neutralized him, but the Device did turn him in to stone. Coulson then put Creel inside a cryogenic stasis chamber and handed him over to Talbot as a peace offering.
Behind the ScenesEdit
In the comics, the Overkill Device is known as the "Overkill Horn".
