C.E.N.T.R.A.L. is the computer located in the War Room that is used by Captain Marvel to decrypt Intel Caches and to dispatch Heroes on Hero Ops.
Iron Man mentions that the first few letters of C.E.N.T.R.A.L. are meant to stand for "Cognitive Encryption Net Transmogrification", but it is not clear if he ever completes the acronym with words for R, A, and L.
