S.H.E.R.B.I.E.

S.H.E.R.B.I.E. is a fictional robot whose name is an acronym within an acronym. It stands for S.H.I.E.L.D. Heuristic Experimental Robot, B-Type, Integrated Electronics, which is quite a mouthful. The character is based on a previous existing robot character known as H.E.R.B.I.E. (same acronym, but without S.H.I.E.L.D.). S.H.E.R.B.I.E. appears in comic books published by Marvel Comics and is associated with the Agents of S.H.I.E.L.D. comic book series.
