During the Black Knights' siege on the Followers of Geass in their Chinese headquarters, cult leader and Britannian ally V.V. uses the Knight Giga Fortress FXF-503Y Siegfried in an attempt to kill Black Knights leader Zero (aka Lelouch Lamperouge). However, the combined efforts of Lelouch and his half-sister Cornelia li Britannia are enough to wreck the Siegfried. Following this, the remains of the nightmarish machine are taken by the Black Knights, and Zero orders the machine modified to serve Jeremiah Gottwald, his new retainer and the Siegfried's original pilot. The redesigned machine, named Sutherland Sieg, turns the Siegfried into a heavy assault craft, loading many powerful weapons and defenses. As the name suggests, the Sutherland Sieg is actually an armed base, controlled by a customized RPI-13 Sutherland which is modified to make use of the mental control system from the original Siegfried. This unique technology, operable only by those with the unique abilities of Geass "Witches," make the Sieg a one-off production unit. Ultimately loyal to his prince more than any nation or military, Jeremiah follows Lelouch when the young man becomes the 99th Britannian Emperor, and fights as a member of his military. In the final battle for Damocles, Jeremiah faces off against Anya Alstreim's RZA-6DG Mordred, losing the Sutherland Sieg and sacrificing the embedded Sutherland in order to disable to Mordred.
