Originally developed by SNRI under the Formula Project as the Gundam F97, the Crossbone Gundam represents the Earth Federation's first earnest attempt at developing mobile suits for use outside of the Earth Sphere. Specifically intended to operate within Jupiter's immense gravity well, the primary thrusters are mounted on flexible X-shaped limbs that can easily be reoriented for high speed or high maneuverability while still letting the machine retain low overall weight. This unique arrangement also allows the Gundam to make use of a full-body anti-beam coating mantle without interfering with its thrusters. When the F97 is given to Bera Ronah's Crossbone Vanguard, it's assigned the model number XM-X to obscure its origins. Fitting with their overall image as pirates, the Crossbone Gundam focuses primarily on melee combat, equipped with beam sabers, heat daggers, scissor anchors, and beam shields which double as brand marker punching daggers.
The Crossbone Gundam's unique weapons are the buster gun beam pistol and the beam zanber, a cutlass-styled weapon with high enough output to easily overwhelm standard beam sabers and shields. These two weapons can be combined into the zanbuster, which functions as a standard beam rifle. Because of its emphasis on close combat, the Crossbone Gundam features thick armor which retains a good deal of heat and must be vented through its faceplate often. Two standard Crossbone Gundams are produced and assigned to the Crossbone Vanguard's ace pilots. The X1 is the custom machine of Kincaid Nau (aka Seabook Arno), the Vanguard's main pilot and leader of its mobile suit forces. Its design, with a navy on white color scheme and relatively orthodox armament, can be considered the closest thing to a "standard" model. During a battle with the Jupiter Empire's elite Death Gale Team, the X1 is badly damaged, giving the Vanguard mechanics the opportunity to revamp it into the X1 Kai.
