Stronger Module

The Stronger Module (ストロンガーモジュール) is the legendary Fourze Module based off of Kamen Rider Stronger, which is equipped on the right arm of Kamen Rider Fourze via the circle-based Stronger Switch (ストロンガースイッチ). The Stronger Module enhances Fourze's punching damage with an electrical charge, which is generated by the spinning "S" on the module.

Behind the scenes
As one of the Legend Rider Modules, the Stronger Module appeared exclusively in Kamen Rider Battle: Ganbaride.
