Originally developed by the Earth Alliance as a successor to the general-purpose mobile suit Leo, this "thirteenth Zodiac" was completed and mass-produced by the Barton Foundation as the main weapon of its Mariemaia Army. Armored with sturdy Neo Titanium alloy, and equipped with built-in missiles and a variety of heavy weapons, the Serpent would be more than a match for other mass-produced mobile suits. But in this postwar era, when the world government has voluntarily disarmed itself, the Serpent's firepower seems like sheer overkill... at least until those pesky Gundams show up.
