Ai

T-Ai, her name being an abbreviated form of "Tactical Artificial Intelligence" (in the English dub), is the sentient computer program which runs the day-to-day operations of the Autobots' base, manning and directing the Global Spacebridge and activating Battle Protocols, selecting suitable members for the mission at hand. She is reportedly the "daughter" of the Teletraan I computer system of the RiD universe. What exactly this means is unknown. She keeps tabs on events across Earth, coordinates Autobot forces across the globe, maintains the elaborate Space Bridge network, and generally keeps things running smoothly at the base (or as smoothly as possible considering the variety of odd personalities that make up the Autobot ranks). To interact with other beings, T-Ai manifests herself as a holographic avatar resembling a young human girl in a maroon uniform, similar to that of a Japanese policewoman, which seems have caught the eye of Koji (who, in the Japanese version, is the only character to affectionately refer to her as "Ai-Chan"). She is an incredibly advanced computer that displays distinct emotions, self-awareness, a sense of humor, and -perhaps most notably- the ability to lose her patience. She is quick to verbally berate any Autobot found shirking their duties - usually Side Burn.
