"G3-X Equip!"
―Makoto's transform[src]

Makoto Hikawa (氷川 誠 Hikawa Makoto) is Kamen Rider G3 (仮面ライダーG3 Kamen Raidā Jī Surī, lit./short for "Masked Rider Generation 3"), the secondary hero used in the 2001 Kamen Rider series, Kamen Rider Agito, using technology in place of the mystic nature of Agito and organic nature of Gills. He's the first Secondary Rider to appear in the series. G3 was based on The Unidentified Lifeform No. 4 or Kamen Rider Kuuga.


He is a cop chosen to use the G3 System to battle the Lords, whom his superiors labeled as "the Unknown", and keep them from murdering people, Hikawa is an earnest, straight forward, and honorable man, though slightly naive and clumsy. Because he was a regular human, the Lords usually ignore him; but sometimes are surprised that a normal human being can wield such power.

One day, while on patrol, Hikawa witnessed the Akatsuki being held by the El of the Sea, taking a boat to investigate and save all but one of its passengers. Because of his heroic role in the incident, which showed his skills in a crisis, Hikawa was assigned to the G3 Unit.

Hikawa took the G3 System on its first run during the Jaguar Lord case, resulting with a feral Agito damaging the Suit. But overtime, while aiding Agito, Hikawa managed to piece together the nature of the Lords' victims. But when Hojo took his place as the G3's user, believing he got the position for being a hero, Hikawa got transferred to criminal investigations for a short while until he proved his skills by anticipating the Zebra Lords' next target, resuming his role in the G3 squad while decking Hojo when he attempted to capture Agito.

Soon after stronger Unknown, and Hojo's Victory One System, made themselves known, Hikawa was given the upgraded and G3-X Suit that is better suited for Unknown Combat and "perfect" in every way. However, the perfection was the flaw as the AI would momentarily take over an impure wearer, as seen when the suit acted on Hikawa's deepest desires when it took control. After consulting her mentor, Ozawa installs a special inhibitor chip to regress the AI.

Hikawa finally learned the true identity of Agito in episode 39 when he cancels his transformation in front of him after being knocked by Another Agito, and Hikawa was visibly shocked to learn Agito was Shouichi, much to his disbelief this makes him lose his cool (even getting in a short argument with Ozawa and Omuro) and expresses disappointment at the revelation and can't accept it at first because the true identity of Agito he admired was far from what he expected. This caused Hikawa to be hesitant on meeting Shouichi. However, their combined effort to defeat Skelos Glaucus caused them to continue their usual relationship, And Hikawa become more respectful towards Shouichi.

After Hojo took over the G3 Unit, Hikawa was transferred back to Kagaki-ken. However, Hikawa couldn't leave just yet, so he and Ozawa take back the G3 Unit. Donning the G3-X one final time, Hikawa aids Agito and Gills in finishing off the Lords for good. By the next year, Hikawa leaves the G3 Unit and returns to being a normal officer of the law.

Kamen Rider Agito: Heaven's Door

There were a lot of killings happening with the recent one being a nude woman found impaled on the top of Tokyo Tower. An Agito was sighted at the scene. While Hikawa was investigating, the Agito and a dog-type Unknown attacked him. Though Exceed Gills and Another Agito appeared to his aid but they were easily getting defeated. Luckily Agito/Shouichi Tsugami finally shown up. The real identity of this Agito was Shouichi Maguichi, who was crazed after being blamed for cheating on the programs for using a hidden camera during his childhood. Wanting to cure his sick mind he worshipped the Dog Orphnoch/Dog Lord and was told to feed on the despair of the public. After Agito and the others killed the Dog Lord/Orphnoch, Maguichi/Agito transformed into Mirage Agito out of rage. In a fight with Kamen Riders Agito and Gills, despite gaining the upper hand he was defeated by the strategized use of the Shining Caliber and a Shining Rider Kick. Maguichi was then arrested and was given an unspecified treatment. Kamen Rider Agito: Heaven's Door

Kamen Rider Battride War Genesis


Kamen Rider G3-X in Battride War Genesis.

G3-X made his playable debut in Kamen Rider: Battride War Genesis, while his original G3 form is only available in cutscene footage only for Agito's Episode 1 scene.

His playstyle requires an extra careful, depending on which special moves he used, will change G3-X's normal attacks, as his weapon sets (except his unused Guard Acceler) can only be changed through special moves instead of normal R1/D-Pad Down change unlike X and the special moves on each different weapons are limited. When the bullets of GG-01 Scorpion/GG-02 Salamender and GX-05 Cerberus (Gatling/Rocket Launcher) are empty, the weapons' bullets can be refill when using different special moves then goes back to one of these two bullet limit use projectile weapon set via special moves involving on using one of these two weapons.

When the gameplay starts, he start with using GG-01 Scorpion/GG-02 Salamender. After using his Super Move, which switches G3-X's weapon into using GX-05 Cerberus by default afterwards, his final state gives him an infinite bullets GG-01 Scorpion/GG-02 Salamender and GX-05 Cerberus.


Hikawa is a hard-working, humble, and selfless police officer. He will blame himself for anything that goes wrong even in cases when it is not clearly his fault. His detective skills made him the first to realize that the Unknowns were targeting people with supernatural abilities. However, these skills often do not extend to his interpersonal relationships-it took Shouichi transforming from Agito into his human form for him to realize his identity as a rider.

However, Hikawa has a slight ego, partially stemming from his clumsiness.

In light of the threat of Unidentified Lifeforms (the Gurongi), Tokyo's Metropolitan Police Department Unidentified Lifeform (M・P・D/S・A・U・L) received funding from the city government to develop a powered, reinforced exo-suit based on the No.4 Unidentified Lifeform, Kuuga to respond to any menace. However, because the Gurongi was eliminated long before completion, research on the project was postponed indefinitely. By this time, the data acquired from the G1 and G2 had been implemented into the Generation-3 (3rd generation exo-armor), which was entering its final phase of development, ready for live-combat deployment. But with the emergence of the Lords, the S・A・U・L's G3 unit was reinstated and recommissioned to contend with the threat. Its most potent armament is the GG-Launcher (GG-02 Salamander).

Using the testbed G3 suit, Sumiko Ozawa went through with the development of this highly-modified exoarmor, using the G3's diagnostic data. All specs and performance potentials have been ramped-up. However, a newly installed AI interface would pose a very serious risk on the operator. The AI's calculations, though perfect, requires precise coordination and synchronization with the suit motor functions. To this end, only an operator with a clear consciousness can operate it without being physically taxing on the body. To this extent, the suit was made "too perfect". However, in light of this, a new control chip with a modified 'scaled-down' AI was installed to make the suit less demanding. It's newest armament, the GX- Launcher (GX-05 Cerberus), can level an Unknown with ease.

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. After the event of the movie, because the G3-X was too damaged, the head and shoulder of the armor was replaced with parts from the G4. 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.

G4-X was essentially Hikawa in the G3-X armor, but due to damage to it’s helmet from his battle with G4 the G4 helmet was used.

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.

    • Kamen Rider G3 is also the first Kamen Rider System that has more than one wearer, barring the original Kuuga, as he was active thousands of years before the current one was even born.
  • Kamen Rider G3-X's eyes and mouthpiece are called (in official materials, but never during the show) Redaizer and Perfector, referring to Kamen Rider X and his original transformation devices.
  • He is the earliest Secondary Rider to appear, even appearing before the Primary Rider (Agito). This was soon followed by the next Secondary Rider, Ren Akiyama.
  • He has an unnamed Rider Kick in Kamen Rider Super Climax Heroes.
