- "And an 0-8-4 is?"
"Object of unknown origin. Kind of like you. Team goes in, determines if it's useful or poses a threat." - ―Skye and Phil Coulson[src]
An 0-8-4 is a term used by S.H.I.E.L.D. to denote an object of unknown origin. Depending on the situation, varying groups of agents are sent to determine what the 0-8-4 is, and how it could be used.[1]
The code "0-8-4" derives from the identification number used on the case containing the first object of unknown origin, as it was the eighty-fourth item catalogued. The object was a Diviner obtained by the Strategic Scientific Reserve, the precursor of S.H.I.E.L.D., during the raid of the HYDRA Research Facility in Austria in 1945.[2]
Leo Fitz explained to Skye that he had never experienced an 0-8-4 being a person, though it was possible. He elaborated by saying that he has read about weapons, spacecrafts, and energy sources labeled as 0-8-4s, citing that the only characteristic they had in common is that all were extremely dangerous.[3]
