The G4-type Reinforcement Carrying Multipurpose Cruise Missile Gigant (G4型強化体携行用多目的巡航ミサイル ギガント, G4 Kata Kyōka-tai Keikō-yō Tamokuteki Junkō Misairu Giganto), or simply Gigant (ギガント, Giganto), is a shoulder-mounted missile launcher that is armed with four large rocket-propelled missiles.
Overview[]
It needs a power supply in order to work from G4's belt by connecting the power cable to an outlet on the left side of G4's Belt. To fire the missiles, G4 must then turn a knob on the right side of the belt. A pair of the missiles then deploy to destroy the target. Used in Kamen Rider G4's finisher.
In G4's first deployment, Shiro Mizuki used the Gigant to destroy a pack of Formica Pedes. When his facility was attacked by the Ant Lords, he used the Gigant as such one more time.
Design[]
- G4 Mark (G4マーク, G4 Māku): A relief showing that the Gigant is operated under the jurisdiction of the Self-Defense Forces as part of the G4 System.
- Target Sensor (ターゲットセンサー, Tāgetto Sensā): A kind of video camera equipped with the same functions as Blueizer, Kamen Rider G4's compound eyes. Send the image of the attack target to the G4 and G4 Unit control room. Instantly calculate the point of impact that gives the maximum damage to the target group and the number of bullets required for annihilation.
- Quadruple Missile Launcher (4式ミサイルランチャー, 4-Shiki Misairu Ranchā): A Gigant launcher. Input the landing point derived by the Target Sensor to each Gigant. In addition, the recoil reduction system enhances stability during firing, and it also has a function to manually guide Gigant after firing.
- Connect Box (コネクトボックス, Konekuto Bokkusu): Contains the power supply cable. When launching Gigant, connect the cable to G4's G Buckle. By receiving the power supply and electrical signal from the G4 side, the weapon lock is released and the Gigant is fired.
- Magnet Grip (マグネットグリップ, Magunetto Gurippu): A powerful electromagnet sticks to G4's knuckles and enhances holdability.
