Technology & Combat Characteristics
The OZ-06MS Leo is an MS developed using data from the OZ-00MS Tallgeese, which was the first combat MS to be created. Its most notable difference from the Tallgeese is that the Leo can be piloted by the average soldier. In addition to being highly productive and versatile, the MS can adapt to both ground and space units by changing equipment. Equipped with an abundance of armaments, such as the 105mm Rifle, Dober Gun and two types of Beam Rifles, the MS is supplied with various options for space and high maneuverability, and is able to cope with all kinds of missions.
History
A simplified version of the OZ-00MS Tallgeese, the OZ-06MS Leo was the first mass-produced mobile suit developed by OZ and has been in operation for several decades with repeated minor changes. In A.C. 195, Zechs Merquise used a Leo to engage the XXXG-01W Wing Gundam just after it entered the atmosphere, and managed to trap the Gundam, sinking both mobile suits into the sea.
Unfortunately, the Wing Gundam was later freed and attacked the bases of the United Earth Sphere Alliance and OZ with four other Gundams. While the Leos were deployed to stop the Gundams, they were no match for the latters' superior capabilities. The Leo was eventually replaced by the OZ's more powerful Mobile Dolls. Despite this, it served as the counterpart to the White Fang's WF-02MD Virgo II during the Eve Wars. After the Eve Wars, it was hardly used as a military weapon due to the trend of disarmament, and became a humanoid heavy machine.
During the "Mariemaia Incident" in A.C. 196, two Leo Space Types were seized by Heero Yuy and Duo Maxwell when they infiltrated the X18999 colony, and dealt a heavy blow to the enemy Leo forces. However, they were intercepted and defeated by Chang Wufei's XXXG-01S2 Altron Gundam and Trowa Barton's MMS-01 Serpent.
