The GAT-X105B/FP Build Strike Gundam Full Package is a mobile suit from the anime series Gundam Build Fighters. The Gunpla is built by Sei Iori and primary controlled by Reiji.

Technology & Combat Characteristics

The GAT-X105B/FP Build Strike Gundam Full Package is a Gunpla built by Sei Iori, and is a combination of the basic GAT-X105B Build Strike Gundam with the Build Booster and new weapons. As indicated by the name, it can be considered as the Build Strike with its complete weapons and equipment. The Build Booster is a support craft that when attached to the Build Strike adds a pair of beam cannons to the suit's standard armaments of four head-mounted vulcan guns and two beam sabers, and also improves its output.[1] The Full Package also gives the Build Strike a Chobham Shield and a handheld beam gun that can transform into a beam rifle, and later into the enhanced beam rifle.


  • Vulcan Guns
The Build Strike Gundam Full Package possesses four head-mounted vulcan guns, which are mainly used to intercept incoming missiles and enemy units at close range.
  • Beam Sabers
The Build Strike Gundam Full Package possesses two beam sabers as its primary close combat weapon. Its beam sabers are powerful enough to destroy an enemy unit with a single hit. When not in use, the beam sabers are stored on the hips of the unit, the same spot where the combat knives are stored on the original Strike.
  • Beam Gun
A handheld ranged beam weapon, it can transform into the beam rifle and later the enhanced beam rifle by attaching additional components. The beam gun is capable of rapid fire and due to its small size, it is suitable for close range combat. Although the beams it fires are weak, they also consume less energy.
  • Beam Rifle
The primary ranged weapon for Build Strike Gundam Full Package. It has variable output and at maximum power, it rivals and can even counter the power of a hyper mega launcher shot. The interior of the barrel contains metal parts for improved durability and to withstand the high output.
  • Enhanced Beam Rifle
As implied by its name, it is an improved version of the beam rifle and retains the variable output as well as the ability to fire a shot with the power of a hyper mega launcher.[1] It is double-barreled to reduce and spread out the stress caused by its poweful shot. At high output, beams are emitted from both barrels to form a poweful blast. During rapid fire, beams are emitted only from the top barrel.
  • Large Beam Cannon
Mounted on the Build Booster, these pair of beam cannons are powerful enough to destroy a enemy unit with a single shot. They are positioned under the shoulders when used by Build Strike Gundam Full Package.
  • Chobham Shield
The Build Strike Gundam Full Package is equipped with a "Chobham Shield" as its primary defensive armaments. The shield consists of superimposed layers that are made from several plastic boards pieced together,[1] allowing it to withstand a beam shot from a hyper mega launcher. The principle behind this is that a portion of the energy in the enemy's beam is dissipated each time a piece of plastic board is destroyed, thus the power of the beam is reduced as it penetrates through the boards and eventually the beam will be stopped by the board.

Special Equipment and Features

  • BB-01 Build Booster
Developed from the MBF-02+EW454F Strike Rouge Ootori's EW454F Ootori Striker, the Build Booster is designed by Sei with high mobility in mind and is armed with only two large beam cannons. When attached to the Build Strike's back, it improved its output by 160%.[1] It can function independently as a fighter aircraft when separated and can allow Reiji to continue to fight even if the Build Strike is destroyed.

  • Despite being based on the Ootori Striker, the Build Booster's weaponry has more similarity with the ORB-01 Akatsuki Gundam's Oowashi Striker.
  • The real life 1/144 model version of the Build Booster is fully compatible with the model kits of the Strike Gundam series such as Strike, Strike Rouge and its variants like the 105 Dagger without the need to use special parts. As well, the Aile Striker can combine with it (with the provided special joint parts).
  • The Build Strike appeared in the first Gundam Breaker game as a DLC unit to coincide with the release of Gundam Build Fighters, though its Build Booster's beam effects were yellow instead of the sparkling red, and only existed in HG form as opposed to every other unit having an MG/1/100 counterpart. These were later rectified in the sequel to match with the release of the MG version of this Gunpla.
