|This article is about a/an weapon in Kamen Rider Fourze.|
The 1 Module (1号モジュール Ichigō Mojūru, #1 Module) is the legendary Fourze Module based off of Kamen Rider #1, which is equipped on the right leg of Kamen Rider Fourze via the cross-based 1 Switch (1号 スイッチ Ichigō Suitchi, #1 Switch). The 1 Module boosts Fourze's kicking power and jumping height.
As one of the Legend Rider Modules, the 1 Module appeared exclusively in Kamen Rider Battle: Ganbaride.
In Movie War Mega Max, Rider #1, as one of the first four of the Seven Legendary Riders, was confined to the form of the 1 Switch by Lem Kannagi; he was freed when Kamen Rider Fourze inserted all four Legend Rider Switches into his Fourze Driver and executed a Limit Break.
