A.R.A.H.C.O.S.

A Rather Awesome Starter Instructional System (A.R.A.S.I.S.) was originally Ayden Jaubert's natural-language user interface computer system, created on Earth-2181, with the aiding and guiding hands of Andrew Carson.

Eventually, following and helping her through her transition into the reality that came to be known as Earth-091991, A Rather Awesome Humanoid Calibrated Operative System (A.R.A.H.C.O.S.) (renamed in Ayarah Costa's and Yara Cos' honor) was upgraded into an artificially intelligent system, tasked with running the newly founded S.H.I.E.L.D. in 1948, before being put in full charge of running Ayden's underground business— the Gemini Network— as of 1989, as well as security for every one of the Jaubert Residences and Gemini Headquarters, scattered across the globe.
