The Zodiac Series

Aries
	Basic Info...
	Model	OZ-07AMS
	Height	16.9 meters
	Weight	8.0 tons
	Armor	Titanium alloy
	Weapons	1 Chain Rifle Optional: Two-tube Missile Pod
	Abilities...
	Fighting	100
	Weapons	110
	Speed	110
	Power	90
	Armor	90
Notes
Aries makes up the majority of the OZ mobile suit force until it is eventually replaced by Taurus and Virgo mobile dolls. However, the Treize faction employs the suit later in their battle against the Romefeller Foundation. It disappears by around the same time as the fall of the Sanc Kingdom and does not show up in the series again.
Cancer
	Basic Info...
	Model	OZ-08MMS
	Type	Amphibious Mobile Suit
	Length	16.9 meters
	Weight	8.2 tons
	Armor	Titanium alloy
	Weapons	4 Torpedo Launchers
	Abilities...
	Fighting	90
	Weapons	100
	Speed	110
	Power	110
	Armor	100
Notes
Cancer is the main marine mobile suit of the Romefeller Foundation. At the time of its introduction, it's the best marine-based mobile suit available, and is used to aid the Alliance's Pisces suits in the search for Wing Gundam. Despite being the best of its kind, Cancer still has a minimal role in the series, due to the fact that most of the series doesn't center around marine combat. Its final appearance is made rather early in the series in comparison to some other suits. Its last battle (I think) was the attack on the Sanc Kingdom, where it provided the sea-bound forces.
Leo
	Basic Info...
	Model	OZ-06MS
	Height	16.2 meters
	Weight	7.0 tons
	Armor	Titanium alloy
	Weapons	1 105mm Rifle (100 rounds) Optional: 1 Beam Rifle 1 Dober Gun 1 Beam Saber 1 Bazooka
	Abilities...
	Fighting	100
	Weapons	100
	Speed	100
	Power	100
	Armor	100
Notes
Leo is the most basic of mobile suits. Because of how widespread its use is, it is assumed that Leo is probably the easiest and cheapest to manufacture, although as far as I know, that's never actually stated. Leo is the main force of the United Earth Sphere Alliance military, and also makes up a good part of the OZ mobile suit force, although it is not as significant as the Aries is to OZ. Leo is a toned down version of the original mobile suit, the Tallgeese. It is heavily based on the Tallgeese design, but is not nearly as powerful as the Tallgeese.
Leo Space-Type
	Basic Info...
	Model	OZ-06MS
	Height	16.2 meters
	Weight	7.0 tons
	Armor	Titanium alloy
	Weapons	1 Beam Rifle (12 Rounds) Optional: 1 "Shorty" Beam Rifle 1 Dober Gun 1 Beam Saber 1 Bazooka
	Abilities...
	Fighting	100
	Weapons	100
	Speed	100
	Power	100
	Armor	100
Notes
The Leo, be it the Space-Type or a regular earthbound Leo, is the basic mobile suit force of the United Earth Sphere Alliance. Although not to the same degree as the Alliance, OZ also uses the suit quite frequently. Despite being surpassed in usefulness and abilities by the newer models, especially mobile dolls, the Leo frequently pops back up in the series, implying that it is probably very cheap and easy to manufacture. Space Leos make up the bulk of the World Nation's attack force during the Eve Wars against the White Fang, and all Leos are based on the original design of the Tallgeese.
Pisces
	Basic Info...
	Model	OZ-09MMS
	Type	Amphibious Mobile Suit
	Length	16.0 meters
	Weight	7.4 tons
	Armor	Titanium alloy
	Weapons	12 Torpedo Launchers
	Abilities...
	Fighting	90
	Weapons	110
	Speed	100
	Power	100
	Armor	100
Notes
Pisces is the Alliance's main marine mobile suit force, but is still inferior to the Cancer model that Romefeller uses. Like Cancer, Pisces vanishes from the series rather early on relative to many other mobile suit models. It first appears in the search for Wing Gundam after it falls into the ocean, and the final appearance it makes takes place when Noin and Sally pilot Pisces suits while recovering Wing Gundam for the Sanc Kingdom. It may have also made an appearance during the attack on the Sanc Kingdom, but I really don't remember right now.
Taurus
	Basic Info...
	Model	OZ-012SMS
	Type	Variable Mobile Suit
	Length	16.8 meters
	Weight	7.9 tons
	Armor	Titanium alloy
	Weapons	1 Beam Rifle Optional: 1 Beam Cannon
	Abilities...
	Fighting	100
	Weapons	110
	Speed	125
	Power	110
	Armor	110
Notes
Taurus is the first of OZ's space-bound mobile suits, although that term may actually be a bit inappropriate, since it functions fine on the Earth, as well. At the time of its first appearance in the series, it is easily the most advanced mobile suit in existence, aside from the Gundams and the Tallgeese. The original model is piloted by a human, but it is later converted to a mobile doll. Taurus is eventually outdone by Virgo, but it is not completely replaced, and even makes a small return in Endless Waltz. On a side note, Taurus is my favorite of the enemy mobile suits.
Tragos
	Basic Info...
	Model	OZ-07MS
	Height	13.8 meters
	Weight	7.7 tons
	Armor	Titanium alloy
	Weapons	1 Beam Rifle Optional: 2 Cannons
	Abilities...
	Fighting	90
	Weapons	110
	Speed	110
	Power	110
	Armor	110
Notes
Well, to be completely fair, "Tragos" isn't a sign of the Zodiac, so technically, Tragos isn't a member of the Zodiac series. Nonetheless, I have included it here, basically just because I didn't feel like giving it its own page and because it's considered part of the Zodiac Series anyway.. Tragos is a variable mobile suit with a very mobile "hover mode" and then a regular mobile suit mode. It's not used very much, but its main appearance takes place when OZ attacks the Maganac Corps. It also shows up several times at other points in the series, including the battle at the Singapore Space Port when the Gundam pilots return to space.
Virgo
	Basic Info...
	Model	OZ-02MD
	Type	Mobile Doll
	Length	16.3 meters
	Weight	7.3 tons
	Armor	Gundanium alloy
	Weapons	1 Beam Cannon 4 Planet Defensors
	Abilities...
	Fighting	130
	Weapons	140
	Speed	125
	Power	110
	Armor	120
Notes
Virgo is only used by OZ, while the Virgo II is the White Fang's model. Virgo first appears about midway through the series as OZ's mobile doll force to replace Taurus. Virgo mobile dolls are manufactured at the Lunar Base, and according to Romefeller's plan, are to be sent to Earth to quell all disputes at once and prevent uprisings. Virgo is the chief force used against the Treize Faction, and a giant force of Virgo suits is employed to decisively defeat the Treize Faction at Luxembourg. Virgo is also used in the defeat of the Sanc Kingdom, and makes several other appearances throughout the series.
Virgo II
	Basic Info...
	Model	OZ-03MD
	Type	Mobile Doll
	Length	16.3 meters
	Weight	7.5 tons
	Armor	Gundanium alloy
	Weapons	1 Beam Rifle 8 Planet Defensors Optional: 1 Beam Cannon
	Abilities...
	Fighting	150
	Weapons	145
	Speed	125
	Power	110
	Armor	120
Notes
Virgo II was designed by OZ, but never left the drawing board until the White Fang got ahold of the plans and began production. The only real difference between Virgo and Virgo II are the slightly increased ability levels, and four more planet defensors. The White Fang rarely uses any other suits, and sends out army after army of Virgo II's at the Gundams. Virgo II is only available as a mobile doll, and makes up almost all of the White Fang's force during the Eve Wars, save for Zechs' Gundam Epyon. The White Fang also employs a new mobile doll system on the Virgo II, in which Dorothy Catalonia utilizes the Zero System, taken from Epyon, to direct the mobile dolls. Until Quatre combats her with his own installation of the Zero System, the mobile dolls with the new system prove quite a challenge for the Gundam pilots.
