Gareth

The Gareth, is the mass-production model of the Gawain. It has similar gold trim at various points, but its overall design is quite different from the prototype. Its Hadron Cannons (its Primary Weapon) are attached directly to its wrists in place of hands. It has eight Slash Harkens mounted in two quad-barrel launchers attached to the hips. It also has fourteen Missile Launchers, four on each leg and six on its chest. Finally, it has two 3-barrel Machine Cannons mounted on its shoulders, RPI stand for Royal Panzer Infantry.

The Glaston Knights switch from Gloucesters to Gareth models prior to the second battle of Tokyo, which is when they were first deployed. Gareths were also widely used during Emperor Lelouch vi Britannia's reign, though they still don't match the numbers of Vincent Wards used (Ward units made up about half of his Knightmare Forces) at the time.

Trivia
