The Powerdizer (パワーダイザー Pawādaizā) is a special exosuit that Shun Daimonji uses to assist Kamen Rider Fourze in battle. The interior appears to generate a large amount of heat, enough to scald Miu when she attempts to use it. Because of this and the large amount of exertion required to make it move, only Shun can bring out its full potential in combat. After modifications made by Kengo and Ryusei, the exosuit no longer gives strains to the user as now it would be fit for anyone to use.
