Generally, the A.I. preferred to cruise the hallways of the Cube in a physical form—its mechanical avatar, the fat tabby mystery which the crew endearingly treated as a pet. It was a six-limbed, three-eyed, puffy-tailed rocat, whose original purpose on the Cube was to function as the craft’s mouser.
While it rarely caught rodents anymore nowadays, it enjoyed wandering the corridors of the Cube during its musings. The rocat was especially long-lived and the crew never had to feed it or clean after it; all they had to do was pet it. The static electricity generated from rubbing its fur charged its fuel cells.
