The GAT-X105B Build Strike Gundam is a mobile suit from the anime series Gundam Build Fighters. The Gunpla is built by Sei Iori and piloted by Reiji.

Technology & Combat Characteristics

The Build Strike Gundam is a Gunpla built by Sei Iori with his own personal modifications. It is based upon the GAT-X105 Strike Gundam that appears in Mobile Suit Gundam SEED. Sei's modifications mainly revolve around improving the suit's mobility and an example of this is the inclusion of thruster units within the new shoulder armor, which resulted in enhanced side to side movement capabilities and allows the suit to better evade enemy's attacks. Thus, Build Strike has superior mobility and excels at rapid attacks. While it is assembled with high technique, its weapons are still incomplete, leaving room for further development. The suit is only armed with four vulcan guns and two beam sabers. It is later combined with the Build Booster support craft and given addition weapons to form the Build Strike Gundam Full Package.


  • Vulcan Guns
The Build Strike Gundam 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 possesses two beam sabers as its primary close combat weapon. Its beam sabers are powerful enough to destroy an enemy unit with either a single swing or stab. 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.

Notes & Trivia

  • Although the opening of the anime features the Build Strike equipped with the beam rifle and the Chobham Shield, these 2 weapons are only used by the suit after Sei completed the Full Package, and as such should be considered to be a part of the latter.
