Fourze's Summer Movie Brings Back the Space Ironmen Kyodain

Early details on Kamen Rider Fourze the Movie: Everyone, It’s Space Time! revealed that the classic tokusatsu duo Space Ironmen Kyodain, Skydain and Grandain, would appear as guest characters, fighting alongside Fourze against the returning villain Meteor. A second guest duo also featured: Inga, played by Cutie Honey’s Mikie Hara, and her partner Black Knight, both pursuing Fourze for reasons left unexplained at the time. Gentaro’s jacket in the film carried an “S-1” marking, echoing the show’s S-1 Switch.

The reveal also teased what appeared to be a new, more powerful upgrade for Fourze, hinted at through a silhouette suggesting a further evolution of his Cosmic States forms, though even the film’s own preview material suggested Fourze at his existing strength wouldn’t be enough to beat back the Kyodain duo’s combined assault on Meteor.
