The RPI-209 Gloucester-Tristan Custom is a Custom Seventh Generation Mass Production Knightmare frame in Code Geass R3: SOD.


The Gloucester-Tristan is based off of the Tristan and Gloucester machines. It has the color scheme of the Tristan as well as its cockpit, but it has the body of the Gloucester.


The machine was designed to be the predecessor to the Tristan, mainly for practice use. It lacks most of the weaponry the Tristan has and it has a different floatation system used mainly for Naval launch.



This machine was a practice frame developed for Gino Weinber before the development of the Tristan and was thought to be scrapped soon after, but it seemed it was preserved and used by unknown forces off the coast of Iceland against Britannian forces. The Tristan-Gloucester managed to hold it's own against the Tristan Divider, thanks to it's Exclaibur swords, also thought to be destroyed.
