"Full Charge!"
―Finisher announcement via Zeronos Belt[src]

The Combination Armament ZeroGasher (連結武装 ゼロガッシャー Renketsu Busō Zerogasshā) is Zeronos' primary weapon. It has two modes, Sabel and Bowgun, and both forms can access them.[1] It has only two components, the blade and a triangular handle. Its components can be swapped with the Denebick Buster.


  • For Saber Mode (サーベルモード Sāberu Mōdo), Zeronos attaches the handle to the blade with the tip of the triangle aligned to the blade. The Aura Saber (オーラサーベル Ōra Sāberu) then grows, almost tripling in size.[2]
  • For Bowgun Mode (ボウガンモード Bōgan Mōdo), Zeronos flips the handle around and attaches it to the Blade perpendicularly. He then pulls back on the blade to open up the 'bow' component of the weapon. The Bowgun then increases in size.[3]


The ZeroGasher is also among the various Rider Weapons used by Ganbarider in Kamen Rider Battle: Ganbarizing.
