Kamen Rider G4

Kamen Rider G4 (仮面ライダーG4, Kamen Raidā Jī Fō) is Rider that only appeared in Kamen Rider Agito The Movie: Project G4.

Shiro MizukiEdit

Shiro Mizuki (水城 史朗) was one of the military personnel guarding the GA psychic educational facility during the time it was attacked by the Formica Pedes. Though he would survive the ordeal, he would be left a jaded man.

With his pride as a soldier shattered, Mizuki began living as one who would embrace death as the true means of becoming stronger. He would eventually volunteer as the operator for the G4 exo-suit and, as fate would have it, clash with G3-X operator Hikawa, to put their ideals to the test on the battlefield. But throughout the course of the battle, the G4 begins to suffer malfunctions.

But despite this, Mizuki refused to surrender. In the end, Mizuki would succumb to the strain placed upon him by the G4 and die. The G4's AI attempted to rise and continue the battle, but was destroyed by Hikawa.

Kamen Rider G4 was an upgraded version of the G3 system conceptualized by Sumiko Ozawa from the G3-X model. However, the G4 was deemed far too dangerous for use, so Ozawa never included the adjustments in the design schematics. But, Risako Fukami would steal the plans and construct the G4 System herself, adding a Prediction System to improve the AI and make the G4 the most powerful weapon on Earth. Unlike earlier G-Series of Kamen Riders motif based on Kuuga, G4's motif was based on Kamen Rider Agito.

G4-X is the upgraded version of the old G4 system. Not much is known about this other than it being a form exclusive to the S.I.C. line. Designed to destroy the rampaging Kamen Rider G1, the suit became more similar to the G3-X system, putting less of a strain and damper on the wearer and sporting a blue coloring instead of black and gray.
