The summer movie of Kamen Rider Agito, shown alongside Hyakujuu Sentai Gaoranger The Fire Mountain Roars.
The movie contains the following tropes:
- A.I. Is a Crapshoot: Inverted. The AI for G4 preforms so well, that if the operator dies, the AI can just take over.
- The Cameo: Hiroshi Fujioka, who played Takeshi Hongo, the original Kamen Rider, appears as the MPD superintendent general and briefly interacts with Shoichi, showing approval for the young man.
- Casting Gag: The superintendent general tells Shoichi that there are things he can no longer do that the young man must, alluding to Hiroshi Fujioka's role as the original Kamen Rider.
- Determinator: Shiro is fully aware of how G4 can kill its operator, that doesn't stop him.
- Deadly Upgrade: The G4 Armour. The AI knows about this and it's programed to function after its operator dies.
- Good Thing You Can Heal: The Ant Lord Queen tears Gills' arm off, but it grows back when he transforms into Exceed Gills.
- The Movie: Notable for being the first Kamen Rider movie to tell its own story (and pretty much started the tradition of Heisei Rider movies to be set in an Alternate Continuity until, arguably, Kabuto or Den-O), and for introducing the concept of movie-exclusive Riders (in this case, G4).
- Militaries Are Useless: The JGSDF can't seem to stop the Unknowns attracted by the strong power of ESPs from the JGSDF research center.
