The Gundam Rose is a mobile fighter created by the space colony of Neo France. It is assigned to the chivalrous George de Sand, whose fencing skills allow him to make good use of the mobile fighter's Chevalier Saber. The cape-like shield on the Gundam Rose's left shoulder houses dozens of remote-controlled Rose Bits, which either attack with their built-in beam guns, or pierce an enemy's armor and then explode. These Rose Bits can surround a foe and attack it from all directions at once in a coordinated Rose Screamer attack, and can also generate an energy field to trap the Gundam Rose's target.
Before the Shinjuku arc, the Gundam Rose was infected with DG Cells. Although it doesn't have any visible changes in the TV series, it is given a new design in Super-Class! Mobile Fighter G Gundam: Shinjuku/Undefeated of the East! that incorporated parts resembling the JDG-009X Death Army. This design features a more cloth-like cloak shoulder armor and can launch more Rose Bits. The Rose Bits now have an Death Army-like eye in the middle of their petals, and the Chevalier Saber has become a physical blade with a vine coiled around it.
As Neo France's entry for the 13th Gundam Fight, the GF13-009NF Gundam Rose was a throwback to old days of chivalry and honor in the Middle Ages. Gundam Fighter George de Sand was no exception to this and adhered to a strict code of chivalry that governed his life. Unlike the selection of other Gundam Fighters, George's appointment as Neo France's Fighter was the result of a tragedy. In a tournament to select their nation's fighter, newcomer George fought against Jean-Pierre Mirabeau and his Mirage Gundam at Versailles. Determined to become Neo France's Gundam Fighter, Mirabeau placed the audience in danger and used them as a shield to prevent George from attacking. Disgusted by this act, the King disqualified Mirabeau and selected George as the Fighter.
