The Cosmic Module Barizun Sword (コズミックモジュールバリズンソード Kozumikku Mojūru Barizun Sōdo) is the main weapon of Kamen Rider Fourze when in Cosmic States, accessed through the 40th Astroswitch, the Cosmic Switch. It first appears in episode 32.

This weapon has two modes: the club/rocket-like Boost Mode (カバーモード Kabā Mōdo) and the orange bladed Sword Mode (ソードモード Sōdo Mōdo).

The Barizun Sword can utilize any Circle Switch Basement-orientated Astroswitch with the sole exception of N Magnet, since it is always supposed to be used with S Magnet (a Square Basement-orientated Astroswitch) as a means to balance out the intense power of the Magnet Switches.

When any of the below (sans Cosmic) are inserted into the Module and activated, it would announce the Switch in the same way the Fourze Driver does, only the voice is different, having a choir-like voice rather than the robotic voice of the Fourze Driver.

  • #1: Rocket - Activates the built-in boosters on the Barizun Sword for increased damage. Super Space Sword
  • #5: Magic Hand - Unknown
  • #10: Elek - Coats the Barizun Sword in Boost Mode in lightning to make it behave like Elek Module Billy the Rod. It can also emit lightning. Monster's Broadcast Star Follower Selection
  • #13: Chain Array - Unknown
  • #17: Flash - Unknown
  • #20: Fire - A fiery energy blade that extends to great lengths. Super Space Sword Ancient City Mayhem
  • #29: Schop - Unknown
  • #33: Claw - A three-pronged rake-like claw that slices through enemies, with the multi-blades hitting multiple areas on the target at once. Winner Determination
  • #40: Cosmic - Unnamed Rider Thrust Limit Break (Boost Mode) or Rider Super Galaxy Finish (Sword Mode)
  • Meteor Storm - Activates the Storm Topper, allowing Fourze to absorb all Cosmic Energy-backed attacks around him by spinning the Topper, then send the absorbed energy back to the target with a spiraling energy blast from the Barizun Sword's blade. Star Luck Ritual

The Cosmic Module Barizun Sword is also among the various Rider Weapons used by Ganbarider in Kamen Rider Battle: Ganbarizing.


  • The Barizun Sword was initially thought to be named after Harrison Ford, but it is actually taken from the Japanese onomatopoeiatic words "Bari" (the sound of booming thunder) and "Zun" (the sound of a thrusting sword).
  • When the Fire Switch is switched on in the Barizun Sword, it behaves like that of Kamen Rider Armed Hibiki's Ongeki Ha: Kishin Kakusei.
