The Double Loading Gashacon Key Slasher (ダブル装填ガシャコンキースラッシャー Daburu Sōten Gashakon Kī Surasshā, lit. "Special Key Slasher") is the personal weapon of Kamen Rider Ex-Aid Double Action Gamer Level X(X) and Maximum Gamer Level 99.


The Gashacon Key Slasher has three basic modes: Blade Mode (ブレードモード Burēdo Mōdo), Axe Mode (アックスモード Akkusu Mōdo), and Gun Mode (ガンモード Gan Mōdo), which Ex-Aid Level XX R and L can switch between by pressing the corresponding mode buttons. However unlike other Gashacon Weapons, the Key Slasher only has its one basic form, merely switching its functionality but not its appearance, save an energy projection blade for Axe Mode.

  • Blade Mode: Press the teal mode button to use the Key Slasher's blade as a sword. This is the weapon's default mode, though the button is still often pressed before entering battle.
  • Axe Mode: Press the orange mode button to project an orange energy ax blade from the front of the Key Slasher's hilt.
  • Gun Mode: Press the yellow mode button to use the Key Slasher's blade as the barrel of a laser rifle.

Special AttackEdit

To activate an attack, Ex-Aid Level XX R / L must press the button of the mode this weapon is in, press 1-3 buttons with the same color in the grid, and then press the mode button again.

  • Blade Key Slash:
  • Axe Key Slash:
  • Gun Key Blast:


By inserting a Dual Gashat or two Rider Gashats (one Level 1&2 Gashat and one Level 3/4/5 Gashat) into the double slot over the back of the Key Slasher's handle, a Rider can trigger a Critical Finish. Using two Gashats will combine them into one finisher using the second word from their names (e.g. Action Robots).

  • The Key Slasher's mode changing announcements are "extended" versions of those from other Gashacon Weapons' similar modes:
  • Its three main forms are possibly a nod to the Kunai Guns from Kamen Rider Kabuto and the DenGasher variants from Kamen Rider Den-O.
    • The Key Slasher's Sword Mode is comparable to the Kunai Guns' Kunai Modes, while its Gun and Axe Modes are comparable to those of theirs. Also, the weapons undergo little major physical change to switch between these modes.
    • However, unlike the DenGashers, the Key Slasher lacks a Rod Mode.
  • Unlike other Gashacon Weapons (save for the Gashacon Bugvisor), this one has three modes while the other weapons only have two.
  • Its name is a reference to keyboards sometimes used for video games, hence the multiple buttons featured on the weapon.
    • As Mighty Brothers XX is a "fan made" of Mighty Action X, it also refers to how most of dōjin games in real life are mostly made for playing in computer softwares.
  • It is one of two weapons designed to hold a single Dual Gashat or two regular Gashats simultaneously to activate a finisher. The other weapon belongs to Para-DX Perfect Knock Out Gamer Level 99, the Gashacon Parablaygun.
