Vergil

Originally, Vergil was a subroutine built into the larger Superintendant artificial intelligence, created by Dr Endesha to look after his daughter, Sadie Endesha. Using the endless resources of New and Old Mombasa, Vergil performed its tasks without fault, although Sadie found it to be a little restrictive. When the Covenant attacked the area, Vergil was instrumental in Sadie's escape from harm in her struggle to reach her trapped father, commandeering numerous vehicles to assist her, as well as the defence of the city by local militia, police, and UNSC Marines.

In his attempts to find Sadie, Commissioner Kinsler shut down the Superintendent, hoping that it would lure her out of hiding. Eventually reactivated, Vergil had been badly damaged, and was near to total system shutdown, saved only by the efforts of a renegade Covenant Huragok. As it worked, the Huragok worked to transfer Vergil to itself, essentially becoming Vergil. Later, the new Vergil would defect to humanity, allowing itself to be captured by Veronica Dare and her team of ODST's to give the UNSC vital information on the Covenant, and their intentions for New Mombasa.
