A seventh generation model, the Tristan 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 very 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 Vibrations Swords called the MVS Polearm, which can be joined together at the hilts to form a single, double-edged scythe. The Tristan is heavily damaged during a battle with the Lancelot Albion.

A modified version of the Tristan is featured in the second opening sequence for the second season. The overall design is similar, but the Float System wings attached to the cockpit are replaced by an X-shaped version resembling those used by the Black Knights. The head is also different, featuring longer red horns, gray coloring, and a golden crown. The MVS Polearm is replaced with twin swords.
