An eighth generation model, the Tristan, named after the Knight of the Round Table, is the first transforming Knightmare Frame ever developed, able to switch between humanoid (Frame) and jet (Fortress) forms. It is piloted by the Knight of Three, Gino Weinberg. It is highly maneuverable, able to fold out and transform in mid-air. It can utilize a pair of machine guns in its jet form. It has two massive Slash Harkens mounted on its forearms, which are equipped with Harken Boosters. The two Slash Harkens can combine to fire an energy blast, powerful enough to effectively match the Shenhu's Baryon Cannon. When in humanoid form, it can wield two pickaxe-like Maser Vibration Swords called the MVS Polearms, which can be joined together at the hilts to form a single, double-edged scythe. The Tristan is heavily damaged by the Lancelot Albion, during the attempted revolt against Emperor Lelouch.

In the manga spin-off Code Geass: Nightmare of Nunnally, Anya uses a modified version of the Tristan. It is similar in appearance to the regular Tristan except for the Geass sigil on the Knightmare's face. It makes its first appearance in chapter 18 to fight the Lancelot. Its main difference to the original Tristan is its weaponry, being six Automated Trajectory Variable Type MVS Slash Harkens.
