Juggernaut One, a juggernaut, fought for the Empire of the Hand alliance. During 8 ABY, it took part in a battle with other juggernauts against the forces of the alien warlord Nuso Esva and the Quesoth species on the Unknown Regions planet Quethold's Red City. While moving along the Setting Sun Avenue, Quesoth Soldiers and Esva's warriors, specifically the Chosen, struck the vehicle, which caused its holocamera to stop working and its speed to decrease. General Tasse then informed Imperial Grand Admiral Thrawn about the state of Juggernaut One.
Soon after this event, the Chosen and the Soldiers infiltrated the juggernauts that were present. Their goal was to seize them, along with their weaponry, to launch an attack on the nearby White City. However, they discovered that the juggernauts, including Juggernaut One, did not have any weapons onboard and were operated by droids.
The novella Crisis of Faith, which was written by Timothy Zahn and released in 2011 as a component of the 20th Anniversary Edition of the 1991 novel Heir to the Empire, featured Juggernaut One.
