343 Guilty Spark

From ILB

343 Guilty Spark was the monitor of Halo 04 until it was destroyed by Master Chief John-117 and Cortana. He is apparently a Forerunner AI, the only one known and one of the few direct links to the Forerunner with a voice. His current whereabouts, plans and activities are unknown.
