The Generation-3 System was developed by the Tokyo Metropolitan Police Department's Squad Against Unidentified Lifeforms division. SAUL had received funding from the city government to develop a reinforced exo-suit to combat the Gurongi, which were known to the police as Unindetified Lifeforms. Their design was based on Kuuga, who was thought to be the fourth Unidentified Lifeform to appear. However, because the Gurongi were eliminated before its completion, research on the project was postponed indefinitely. By this time, the data acquired from the first two phases of the project had been implemented into the Generation-3 System, which was entering its final phase of development and ready for deployment. With the emergence of the Lords, the police's G3 unit was commissioned to contend with the threat.

By the time of Kamen Rider Zi-O, the G3 System has been mass-produced, presumably using data from G3 Mild.

Despite using advanced technology, G3 is vastly outclassed by the Lords and those that possess a Seed of Agito, leading to it being overwhelmed in its first battles.

G3 is equipped with conventional ballistic weapons. His primary armament is the GM-01 Scorpion, which is holstered on his right hip. The Scorpion can be augmented with the GG-02 Salamander grenade launcher, which serves as G3's main method of destroying Lords. For close combat, he can equip the GS-03 Destroyer on his left arm. The Guard Acceler, which is used to access the Guard Chaser or can function as a backup weapon, is stored on the left thigh.


Kamen Rider G3-X

  • Rider Weight: 176 kg

Rider Senses:[1]

  • Eyesight: 15 km
  • Hearing: 15 km

Ability Parameters:

  • Punching Power: 2.5 t[1]
  • Lifting Power: 20 t with GA-04 Anthares[2]
  • Kicking Power: 7.5 t[1]
  • Maximum Jump Height: 20 m[1]
  • Maximum Running Speed: 100 m per 8 seconds[1]
  • Defense: 10[1]

Special Attacks:

The Generation-3 Extension is an upgrade to the G3 System developed by Sumiko Ozawa in order to address G3's failure to effectively combat Lords. G3-X offers a drastic improvement in combat ability, allowing it to fight on more even ground. However, its most notable addition is an on-board AI to assist the operator. However, the AI's implementation was revealed to be seriously flawed. The AI's calculations, though perfect, required precise coordination and synchronization with the suit's motor functions. If the operator could not coordinate with the AI, G3-X would act erratically by itself and damage the user's body in the process. To address this issue, a new control chip with a less advanced AI was installed to make the suit less demanding.

In addition to the standard GM-01 Scorpion, G3-X's main armament is the new GX-05 Cerberus, a powerful vulcan gun that allows for modular customization. It can be equipped with a scope or docked with the Scorpion and converted to a missile launcher. For close combat, G3-X replaces the Destroyer with the GK-06 Unicorn, an electromagnetic combat knife stored on the left arm.

G3 Mild

Kamen Rider G3 Mild

Rider Statistics:[2][5][6][4]

  • Rider Height: 185 cm
  • Rider Weight: 125 kg

Rider Senses:

Ability Parameters:

G3 Mild is a test unit for a mass-production model of the G3 System. It incorporates parts from both the standard G3 System and G3-X. However, funding was inadequate, causing the development of mass-produced G3 forces to stall. The suit is still in its early prototype stage, resulting in it being even weaker than the standard G3 System. The automatic fitting function from the G3 System was adapted so that anyone could equip it. To test this function, Takahiro was chosen to use the system.


  • Guard Acceler: An electromagnetic jutte, stored on left leg, hand-carried or inserted into Guard Chaser throttle port in use
  • GM-01 Scorpion: A modular magnum pistol, stored on right hip, hand-carried in use. Compatible with the GG-02 Salamander module attachment
  • GG-02 Salamander: A grenade launcher module that could be attached to barrel of the GM-01 Scorpion.
  • GS-03 Destroyer: A high-frequency sword, mounted on left arm when in use.
  • GA-04 Anthares: A wire-anchor hook, mounted on left arm when in use.
  • GX-05 Cerberus: A multi-mode Gatling gun, hand-carried in use; modular attachment include GM-01 “Scorpion” and tracker scope; exclusive only to the G3-X
  • GK-06 Unicorn: An electromagnetic combat knife, stored left arm, hand carried in use.
  • Guard Chaser: G3's motorcycle that was served as the successor to the TryChaser series of motorcycles, which stores his primary weapons, based upon the designs of Kuuga's TryGouram/BeatGouram bikes.
  • G-Trailer: G3's base of operations which was operated by Ozawa and Omuro.

Behind the scenes


G3-X with Riot Shield

G3-X concept with riot shield.

During the planning of G3-X's design by PLEX, he was originally going to be equipped with a riot shield. For some unexplained reason, this idea was scrapped from the final design. This concept, while never used in the series, would be featured on the dust jacket of the book Kamen Rider Art Collection Hero Hen.




  • A set of G3-X's chestplates were painted silver and repurposed as part of the V-1 suit.
