Gilliam II is the artificial intelligence system of the Outlaw Star. Primarily communicating through speakerphones, an interface on the bridge, and a seemingly limitless number of miniature maintenance robots, Gilliam is a constant companion of the crew, and assists them in all areas of the ship's upkeep – even including the kitchen duty. Sporting a wryly sarcastic, if soft-spoken and humble, personality, Gilliam has been referred to as an "old man," and indeed, is almost always engaged in reminding the crew of their personal duties and responsibilities, much as a father-figure or a butler might. This often irritates Gene, who would rather sleep late and shirk chores, and Gilliam, as a result, is frequently compelled to confront Gene about his laziness and inadequacy. Gilliam also regularly voices concern over his "future prospects" due to the brash nature of Gene's captaining.
