Aziru of Akharan is the former host of the Goa'uld System Lord Ba'al. He was his host for over two thousand years. (SG1: "An Eye for an Eye")

After Ba'al was deposed, he stopped using his Goa'uld voice at all times and used his host's voice predominantly. Ba'al made several clones of himself, but all of them were eventually killed, except one. This clone's symbiote was extracted from the host by the Tok'ra and killed. The host survived the extraction and Vala Mal Doran offered to help him cope, as she knows what it is like to be the host of a Goa'uld. This cloned version of Ba'al's host is the only known host of a major System Lord who has been freed from its symbiote. (SG1: "Continuum")
