The Sovereign is the title given to the leader of The Guild of Calamitous Intent. Most of the communication between the Sovereign and the rest of the Guild takes place through a monitor through which the leader is shown as a giant red-colored head.

During the events of Showdown at Cremation Creek, the current Sovereign is revealed to be David Bowie. Bowie shows up to the Monarch and Dr. Girlfriend's wedding with his minions in tow, only to be betrayed and almost murdered by Iggy Pop and Klaus Nomi, under the order of Phantom Limb.
