"A Knightmare Frame with advanced technology and powered by the unique Geatic Mega Drive, an unexplained source of power that is near limitless."
Antonio Mason on his brainchild, the GGK-01 Uther.

The GGK-01 Uther, literally meaning the Geass Generation Knightmare-01 Uther, is a Prototype Design based off the early design for the Z-01 Lancelot and was designed by the Critical Faction under request by the Loki Conglomerate.

The Knightmare Frame was, as mentioned in the Dawn of a New Empire series, used during the time of Code Geass: Lelouch of the Revolution R1 and late in the series it used its connection system to combine with the GKGF-01 Igraine, acting as the Knight Giga Fortress' Cockpit unit.


The design of the Uther is described as unique especially with the new type of technology that is being used in this Knightmare Frame design, the Uther was designed to use Beam Weapons that were designed by the head of the Critical Faction: Archduke Antonio Mason, a rival of Earl Lloyd Asplund.
