The Prophet of Disdain is a San'Shyuum only known from a Halo 2 match held at E3. During this match, players used premade accounts with the names of Halo characters. One team played as SPARTAN-IIs and used Marine names, such as "Mendoza" or "Stacker," while the other team played as Elites, using Prophet names including "Disdain."[1]

It is unknown whether or not he had been planned for Halo 2, but he never made it into the final game.
