The mainstay of the Alliance Mobile Suit forces, the “GUARDIAN” is a modular Mobile Suit that can change it’s gear setup depending on the battlefield it is confronted with, a revolutionary idea when it was first introduced at the outset of the Solar War. While quite successful in the beginning of the conflict (when it held an impressive average 3 to 1 kill ratio), it didn’t take long for the EAU to completely sublimate (and even improve) on the original design developed by the Alliance and incorporate into their own mobile suit forces. Nevertheless, several successive upgrades in design and technology have seen them more or less reach parity with the Valkyrie suits typically used by the EAU, although in some areas (such as modular armour design) the Valkyrie’s still hold the edge.
