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.[1] Thus, Build Strike has superior mobility and excels at rapid attacks.[2] Compared to the Strike Gundam, the Build Strike's close combat abilities are improved with four vulcan guns and two beam sabers.[2] While it is assembled with high technique, its weapons are still incomplete, leaving room for further development. It is later combined with the Build Booster support craft and given addition weapons to form the Build Strike Gundam Full Package.


  • Vulcan Gun
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 Saber
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.


Build StrikeGundam was built by Sei Iori to conpete in the 7th Gunpla Battle World Championship. Sei's mother, Rinko Iori, said that the Gunpla has the same essence as his father's Gunpla used at the 2nd World Championship. But sooner Sei was challenged by Susumu Sazaki to win a battle with his Gyan, betting his Gunpla to be used by Sazaki. At that time, Build Strike was only eqquiped by vulcans and beam sabers. Sei then battled Sazaki, until Build Strike cornered and was about to be pushed out fron the field. Luckily, Reiji came out of nowhere because Sei made a wish, and defeated Sazaki. The rumor was spread until Yuuki Tatsuya heard about it. Knowing that Sei brought Build Strike to Seiho's, Monta Gondachallenged Sei and Reiji to a duel with his Sumo. They agreed, and the Sumo destroyed when the Build Strike charged onto it and attacked it with the beam saber. After defeated by Zaku Amazing, Sei build the [BB-01 Build Booster]] and attahced it to build 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.
