The XM-X1 Crossbone Gundam X-1 "Patchwork" is the repaired variant of XM-X1 Crossbone Gundam X-1 Kai Kai "Skull Heart" and made the appearance in Mobile Suit Crossbone Gundam: Steel 7. The unit is mainly piloted by Tobia Arronax.

Technology & Combat Characteristics

In order to quickly repair the XM-X1 Crossbone Gundam X-1 Kai Kai "Skull Heart", SNRI made use of spare parts leftover from Tobia Arronax's original XM-X3 Crossbone Gundam X-3. It should be noted, the three original Crossbone Gundams were not three distinct units but rather three minor variations of the same base mobile suit. As a result, X-3's spare parts could be applied to X-1 with no trouble at all. In order to keep one mobile suit in working order, one needs enough spare parts to produce three units; thus, SNRI kept many spare parts from the X-3 in storage following the Jovian War. However, because the technology involved (especially the downsized I-field hand) was top secret, SNRI hid the existence of these spare parts even from the Crossbone Vanguard, only bringing them out of the warehouse because it was absolutely necessary. The "Patchwork" can also equip the hook shield, a Federation technology used mainly to collect space debris; because it needs to be able to resist strong impacts, it also functions as a very sturdy solid shield.�


  • Vulcan Gun
These head mounted shell firing weapons have a high-rate of fire, but have little power and are generally ineffective against mobile suits; however, the vulcan gun can damage lightly armored areas such as the sensors. These weapons are ideal for shooting down small, fast moving, lightly armored targets such as missiles or small vehicles.
  • Mega Machine Cannon
The Crossbone Gundam is equipped with a pair of fire-linked mega machine cannons in its chest. In the age of miniaturized mobile suits, the emphasis for mobile suit designs is speed, thus armor is sacrificed to reduce mass and weight. This leaves many mobile suits vulnerable to physical round weapons, such as machine guns, that had been discarded for mobile suit combat because of a lack of effectiveness after the One Year War. Though based on the concept of old mobile suit machine guns, the mega machine cannons mounted in the Crossbone Gundam's chest have been improved with modern technology, making them more effective.
  • Beam Saber
The beam saber is the standard close-combat melee weapon of mobile suits descended from the RX-78-2 Gundam, and many other machines developed in the years after the One Year War. Beam sabers are powerful weapons that emit a blade of plasma contained by an I-field that can cut through any physical armor. The only way to fully defend against a beam saber is to block it with another beam saber or a beam shield. Because of the I-field a beam saber can be used to block an attack from a beam rifle, but this is a technique that requires considerable skill, and can only block an attack of so much power. The Crossbone Gundam is equipped with two beam sabers stored in shoulder racks when not in use. They also serve as the beam guns for the core fighter.
  • Heat Dagger
The Crossbone Gundams are also equipped with two heat daggers as alternative close combat weapons. Unlike most heat weapons, the blade of the heat dagger is heated using leftover heat from the leg's thrusters. The heated blade can melt the enemies armor on contact, which when combined with the force applied to the attack, can inflict significant damage. The heat daggers are stored in the legs, one in each calf. Normally, it is handheld when in use, but it can also slide out of the sole as a surprise attack.
  • Scissor Anchor
  • Screw Whip
  • Beam Zanber
The beam zanber is a high power beam saber and is the primary weapon of the Crossbone Gundam. The hilt of the beam zanber is modeled after that of a traditional pirate cutlass, as does the beam blade when it is formed, and is stored on the left hip when not in use. The power of the beam zanber is significantly higher than that of ordinary beam sabers, such that it is easy for the Crossbone Gundam to overpower an enemy in melee combat or even "cut" through the beam of an ordinary beam saber. Behind the guard of the beam zanber is a gun handle that is used in the zanbuster configuration.
  • Buster Gun
The buster gun is the primary ranged weapon of the Crossbone Gundam. This beam pistol is modeled after a flintlock pistol and is typically used with only one of the mobile suit's hands, leaving the second hand free to use a melee weapon. Stored on the right hip when not in use the buster gun can combine with the beam zanber to form the zanbuster.
  • Zanbuster
A beam rifle formed from the combination of the beam zanber and the buster gun, the beam it fires is stronger than those of the buster gun. In this configuration, the butt of the buster gun is connected to the beam emitter of the beam zanber. When a grenade is attached to the Zanbuster's emitter, it can also function as a single shot grenade launcher.
  • Rifle Grenade
The rifle grenade is a high yield explosive that can be attached to the beam emitter of the zanbuster.
  • Atomic Shell
An alternative weapon that can be fitted to the beam emitter of the zanbuster, it is fired in the same manner as the rifle grenade.
  • Hook Shield
  • Hi-Murasame Blaster
  • Peacock Smasher
