Cornelia's Gloucester is a custom model specifically customized and tailored to Cornelia li Britannia's skills as a high end knightmare pilot and commander. It's largest appearance was during the Battle of Narita and was seen in every other major battle Cornelia participated in. The unit was severely damaged during the Black Rebellion at the end of the first season when Andreas Darlton, under the influence of Lelouch's Geass, threw his lance at it and impaled it through the cockpit, badly wounding Cornelia.
