Gridman Calibur

"Access Code: Gridman Calibur!"

―Calibur's transformation call.


Gridman Calibur's default mode. When used by Full Powered Gridman, the Axe Blade (アックスブレード Akkusu Burēdo) is detached and combines with Buster Borr to form a more developed chestplate.

  • Flight: The Gridman Calibur is somehow capable of flight, for at least a short duration.
  • Beam Blocking: The Gridman Calibur is capable of, to some extent, blocking enemy attacks
  • Grid Calibur End (グリッドキャリバーエンド Guriddo Kyaribā Endo): While using the Gridman Calibur, Gridman moves towards his enemy via the thrusters on his back, and slashes with his sword.
  • Full Power Charge (フルパワーチャージ Furu Pawā Chāji): Full Powered Gridman holds the Gridman Calibur upwards, charging energy as his armor becomes covered in a golden aura.
    • Grid Full Power Finish (グリッドフルパワーフィニッシュ Guriddo Furu Pawā Finisshu): Using the Full Power Charge, Full Powered Gridman covers the Gridman Calibur with a golden aura, which becomes a large beam fired at the enemy.


Gridman Calibur Axe Mode (グリッドマンキャリバー・アックスモード Guriddoman Kyaribā Akkusu Mōdo) is wielded by Powered Zenon. The Axe Blade (アックスブレード Akkusu Burēdo) opens up and is moved nearer to the tip of the blade.

  • Powered Axe Jumbo Saber Slash (パワードアックスジャンボセイバースラッシュ Pawādo Akkusu Janbo Seibā Surasshu): Powered Zenon charges the Gridman Calibur (Axe Mode) with blue lightning before striking an opponent with enough energy to cleave them in half.


  • His counterpart in Denkou Choujin Gridman is Gridman Sword, a weapon that was created by Compoid and Anosillus after saving the latter monster from Takeshi Todo's brainwashing. His Axe Mode is a throwback to the Gridman Sword's alternate mode, Thunder Axe.
    • His name is based off the Samurai Sword, the name for the Gridman Sword in Superhuman Samurai Syber-Squad.
    • Since the rest of his teammates references both Team Samurai and their Assist Weapons, Samurai・Calibur had his name being an alliteration of Sam Collins, Naoto Sho's counterpart in the American adaptation.
  • His ability to change into a weapon brings in mind to Neotaro/Teddy from Saraba Kamen Rider Den-O: Final Countdown, an Imagin who transforms into Macheteddy for Kamen Rider New Den-O to use.
  • He often forgets about the length of his swords and has to make a conscious effort to avoid him getting stuck at the doorway.
  • The brooch on his vest is a reference to the Dinobot, Slug, from Transformers Age of Extinction.
  • According to the voice drama episodes:
    • He states that he is 33 years old but whether that is true or not is unknown due to his secretive nature and role and also the fact that he was told to cover up his identity. Restoration#Voice Drama 2.2
    • Calibur likes cats and has several of them at home. He also states that he would adopt an abandoned cat if he found one.Provocation#Voice Drama 5.5
