"What a talented yet unreasonable man."
Chikara Saionji[src]

Igor (イゴール Igōru) is a scientist from the Gamma World. Like Jabel, he is also a Gamma Superior. He has a black-colored wrist device called Proto Mega Ulorder which allows him to channel the power of Eyecons.

Making a rival of Akari Tsukimura, she refers to him as "KMS" (ケイエムエス Kei Emu Esu), an abbreviated nickname she coined from Kanpekinaru Mad Scientist (完璧なる・マッド・サイエンティスト Kanpekinaru Maddo Saientisuto, Perfectionalist Mad Scientist). Explosion! Paint From Your Heart!

Following the banishment of the previous Gamma magistrate and his superior, Edith, Igor is declared the new magistrate by Adel himself.

Character History


Circa 2005, Igor had been in contact with Ghost Hunter Chikara Saionji, and had him send the young siblings Makoto and Kanon Fukami through the Monolith to the Gamma World. Kamen Rider Ghost: Truth! The Secret of Heroes' Eyecons!

Supporting the Prince Adel, it was Igor and he who suggested an invasion of the human world in order to obtain the vital energy needed to maintain the Gamma life support system. Subsequently, an initiative to convert the Earth to the image of their world was prepared and launched on October 3rd, 2015. Upheaval! The Magistrate's Decision!

After Saionji's disappearance, Igor recovered a collection of artefacts he had assembled, including Leonardo da Vinci's Mona Lisa, and gathered them in his residence. Kamen Rider Ghost: Truth! The Secret of Heroes' Eyecons!

The Necrom System

Igor first appears at Adel's side in the world of the Gamma as he observes Alain using the Kamen Rider Necrom system in the human world. Perfect! The White Kamen Rider!

Collecting Souls

With the Knife Gamma

Commanding the Knife Gamma, Igor had him begin collecting human souls for the Gamma World which he would examine for purity in his container. Igor was eventually confronted by Akari Tsukimura and Onari Yamanouchi and ordered the Knife Gamma to deal with them. It was here that Igor met Specter for the first time as he arrived to cover Akari and Onari's escape. Refusing to answer to Specter, Igor took his leave before Alain came to acquire Specter for himself. Igor later saw Akari deduce that the Knife Gamma's masking fog was emitting a magnetic field while attempting to counter it with her Shiranui Kai, voicing that at least someone in the human world was capable of critical thinking. Facing the human scientist, Igor flaunted his philosophy of a perfect world before posing the question of how she was able to find him. When it was revealed that it was due to a woman who could see the future, Igor sent Knife Gamma to take her soul for analysis only for Akari to take the hit, an act which he derided her for much to the offense of Onari and Takeru Tenkuji who staunchly defended her, with the latter transforming into Ghost Toucon Boost Damashii and engaging Knife Gamma. Watching the fight, Igor moved to hinder Ghost by summoning the captive souls, forcing them to encircle Ghost. However, much to Igor's bewilderment, Ghost used Himiko Damashii to free the captive souls before destroying Knife Gamma. Igor recovered the pair of scissors used to create the Knife Gamma, and voiced that the results were still satisfactory. Gorgeous! The Fantastic Queen!

Gamma Superior Knife

Using his Proto Mega Ulorder, Igor would don the mantle of Knife Gamma himself as he continued collecting souls, observing that fear increased the purity of the soul. On his hunt, Igor crossed paths with Alain, confirming that he was indeed sent on the orders of Prince Adel to "babysit" Alain in Jabel's place. Confronted on not reporting to him when he arrived, Igor retorted that it was not necessary as Alain was not in charge of him. Resuming his collection, Igor would be met by Akari and Onari again as he took Narita's soul. Akari conceded that Igor may be from a perfect world, but his actions were a betrayal of science. Refusing to argue, Igor proceeded to take her soul as well. Having analyzed the output of her Shiranui Kai, Igor effortlessly resisted her attempt to oppose him as he moved to strike only for Onari to take the blow. Observing that Onari's soul lacked purity, Igor branded him worthless, leading Akari to defend her friend as defiantly as he did for her before firing a second blast of Shiranui Kai which proved more powerful as it successfully forced Igor back, baffling him as Takeru cited it as an example of human potential. Engaged by Ghost Toucon Boost Damashii, who told him that a perfect world had no point without hopes and dreams, Igor responded by overwhelming him with Knife's fog. However, by using a combination of Himiko's power with the repulsion of Newton, Takeru was able to dispel the fog before defeating Igor. With his Knife Eyecon destroyed and all the souls he had stolen returned, Igor noted that this was beyond his calculations before returning to the Gamma World. Reverse! Mysterious Science!

Starting the Demia Project

Taking over Deep Connect

In the Gamma World, Igor was given orders by Adel to move to the next phase, being offered the position of magistrate should he be successful. Assuring Adel that he would not disappoint, Igor returned to the human world and moved to begin the Demia Project so that the world may be purified, as well as for the sake of his own success. Having the Gazai Gamma paint the Deep Connect building, resulting in the creation of a physical disturbance upon it, Igor sent him to continue his painting across the city as he entered Deep Connect, observing the facility's resources as primitive yet sufficient for his objective as he comandeered them for himself. Entering the office of CEO Steve Bills, who was preparing to leave the building amidst the confusion, Igor negated the disturbance by tearing Gazai's drawing in half before using a Gamma Eyecon to possess Bills, making him his pawn. Reconvening with Gazai Gamma, Igor ordered him to return as operations progressed only for Gazai to refuse, stating that he wanted only to paint. Attempting to bring in the Gazai Gamma for reeducation by force, Igor was confronted by Ghost Toucon Boost Damashii, who chose to befriend Gazai having seen the potential for good in him, a friendship which Igor believed to be unnecessary for a perfect world. Transforming, Igor assumed the Machine Gun Gamma Parka Ghost to fight Ghost who assumed Toucon Benkei Damashii in response, maintaining that he could befriend the Gamma by connecting with his heart before defeating Igor who vanished. Explosion! Paint From Your Heart!

Dealing with Gazai Gamma

Returning to Deep Connect, Igor introduced himself to the board as Steve Bills announced that the company would be taking a new direction under his supervision. Igor promptly brought forth the Gamma Eyecons to make the board his puppets as well. Following this, Igor caught up with Gazai Gamma again, insisting that he return and proceed to the next step only for Gazai to refuse him, pleading to be left to paint. Voicing that Gazai had been throughly corrupted by the "impurities" of the human world, Igor proceeded to eliminate him before being met by Takeru, whose ideals of friendship he continued to scoff at, calling them "illogical". Engaging Ghost Toucon Boost Damashii in battle, Igor assumed Seiryuto Gamma's mantle with Ghost assuming Toucon Musashi Damashii in return. Igor soon left the fight to advance on Gazai, attempting to strike him down only for Ghost to take the hit, telling Igor that he would not let him hurt his Gamma friend. As Ghost prepared his Omega Drive, Igor said that this was not the venue to exhibit his true potential anyway and so left. Explode! Flames of Friendship!

Binding the Katchu Gamma

At Deep Connect, Igor remotely observed Steve Bills outlining the Demia Project to the wider business community and noted favorable results according to plan. Handing his soul container to the Katchu Gamma, Igor ordered her to eliminate both Ghost and Specter and to retrieve their Ghost Eyecons. However, Katchu, citing unexpected interference, ultimately came back fruitless. Igor, realizing that her knight's sense of nobility was an weakness, lamented that he was left with another inefficient Gamma before forcing her to submit to his will, insisting that she took any means necessary to retrieve the Eyecons. Katchu proceeded to mercilessly hunt for human souls, with Takeru's friends being among her victims. Igor was pleased to receive the Eyecons of Ghost, who had been forced to relinquish them in exchange for the souls' safe return only for Igor to go back on the promise, citing souls as a valuable resource as he ordered Katchu Gamma to deliver them to their world after defeating Ghost before taking his leave. Amazing! The Gamma's World!

While making good progress with Steve Bills, Igor was profoundly disappointed to find Katchu Gamma, who had been freed of her brainwashing while fighting Ghost, return without success again. Painfully disciplining the Katchu Gamma, Igor ordered her to eliminate the traitor Gazai Gamma, warning her that he would not tolerate failure again. Ultimately, Ghost was forced to finish Katchu Gamma in battle. Conspiracy! Adel's Trap!

Alain's Banishment

Following Alain's reduction to his flesh body and banishment from the Gamma World by Adel, Igor sends a force of Gamma Commandos led by the reincarnated Machine Gun Gamma and Seiryuto Gamma to kill him, only for them to be all destroyed by Ghost Grateful Damashii. The Legend of Hero Alain: Chapter 2 Appearance! The Mysterious Warrior!

The Red Sky

Igor reported to Adel on his progress in the human world, assuring that the Demia Project as going according to schedule, despite Jabel's failure. Adel told Igor that Jabel was no longer of concern and ordered him to move to the next phase of the operation. Acting on Adel's orders, Igor sent the younger Hikoki Gamma to begin the creation of a red sky just as that of the Gamma World within the human world. Igor oversaw the progression of the red sky and was satisfied to see it move unhindered. Disaster! The Red Sky!

Soon enough, the elder Hikoki Gamma joined in, and Igor was pleased to note that the progression was going perfectly. Igor was then approached by Jabel who had returned, increasingly weak in his bruised and exhausted flesh body, seeking help only for Igor to unsympathetically note that, having been only of worth as a fighter, Jabel was now useless and thus disposable. Enraged, Jabel attempted to attack Igor only to collapse to his knees. Calling Jabel pathetic, Igor abandoned him as he noted that he would soon be dead along with Alain. Later, as the elder Hikoki Gamma reported back to him, Igor was met by the exiled Alain, who asked him to erase the red from the sky. Igor, noting that he had wanted to reform the human world in the image of their own as well, asked Alain if he even knew what it was that he wanted anymore. Assuming the mantle of Book Gamma, Igor swiftly overwhelmed the weakened Necrom, noting that Alain would ironically die at the hands of the utopia he initially sought, sparing him only to make sure he suffered just a while longer. However, Alain received unexpected assistance from Grimm which allowed him to fight back against Igor with Hikoki joining the fight. When Ghost Toucon Boost Damashii arrived to help Necrom, Igor quickly made his escape with Hikoki. Conflict! The Terms of Resolution!

Preparing his Fanfare

Following the negation of the red sky, Igor pondered how someone could have reverted the atmosphere and thwarted his plan, a feat which should have been impossible for mere humans, soon realizing that Akari was responsible. Igor began the next phase of his operation, having the Onpu Gamma create a musical composition to be played at the launch of the Demia Project, a piece that would convey the magnitude of his glory. Do-or-Die! Ready for Infiltration! Igor was most displeased, however, when he saw the finished result, trashing the piece and ordering Onpu Gamma to do it again. However, despite repeated attempts, Onpu Gamma's work failed to satisfy Igor and the Gamma ultimately gave up and ran away. Pursuing Onpu Gamma, Igor eventually found him with Gazai Gamma. Finding that Onpu wished to compose music only as he liked, Igor lamented that he was faced with another defective Gamma before moving to eliminate them both, adopting Knife Gamma's Parka. Though the rogue Gammas and Takeru's friends attempted to defend themselves, they were ultimately at Igor's mercy until Jabel unexpectedly appeared to stand Igor's way, assuming his Gamma Superior form before swiftly beating back Igor. Jabel explained that this was as a debt to Onari, who had nursed him back to health earlier, before leaving as soon as he came. Forced out of his transformation, Igor persistantly vowed to eliminate them all only to be told to stand down by Akari, who slapped him in the face leaving a visible mark. Berated by Akari at how he, as a scientist, could regard the Gammas as defective because he couldn't see the value in their hearts, Igor could only run away without retort. Bursting! Power of the Depths!

Furthering Deep Connect

Recruiting the Dead

Using a Gamma Eyecon, Igor resurrected the deceased programmer Kensuke Shirai through his glasses to serve as a worker in Deep Connect's Development Department, having the room protected by a forcefield. Alongside Steve Bills, Igor would find that Takeru and Akari, whose presence irritated him especially, were pursuing Kensuke with his daughter as they entered Deep Connect before being forced to retreat when the Gamma arrived. Backed-up by a small army of Gamma, Igor intercepted the Kamen Riders and their allies as they attempted to enter the Deep Connect building in search of Kensuke Shirai again, engaging them as Gamma Superior Ono. Stopped from catching Akari and Yuki on their way to the Development Department by Necrom, Igor's fight with the Riders was taken to the car park where Igor escaped with Planet Gamma by using a fellow Gamma Superior as a meat shield. Second Coming! Ordeal of the Escape King!

Securing Deep Connect

Realizing that his control of Deep Connect was at risk from the Mysterious Phenomenon Institute, Igor arranged to get them off his back, having Steve Bills accept a meeting with Yuki Shirai as well as making a plea to Takeru to "save" his company from the incursion. Accompanied by a force of Gamma, Igor appeared to stop Bills from showing Yuki the Development Department, punching him in the face and assuming Gamma Superior Ono again before being engaged by Deep Specter. Yuki found her father proceeding to the Development Department with other workers, unresponsive to her appeal, with Igor explaining that he brought him back heartless before revealing that his work is done, having the Development Department self-destruct before leaving. Following this, Igor had Steve Bills give his assurance via phone call that he would be searching and purging his company of the Gamma, before meeting with Takeru and Akari later to inform them that his company was secure as he gave them his thanks, all the while they were totally unaware that he was infact a puppet under Igor's watch. Forever! Cries of the Heart!

Stepping Out

Noting that Bills had completely won over the trust of the Mysterious Phenomenon Institute thanks to his plan, Igor ordered him to continue the operation as he stepped out, explaining to Bills that something that had piqued his interest was unfolding. Igor later watched from a distance as Alain and the other Riders were confronted by the Gamma enforcer Gyro, who Igor deduced to be a replacement for Jabel, envisioning that he would provide even more entertainment. Seeing the three Kamen Riders forced to retreat in the face of this overwhelming and intimidating opponent, Igor noted that Gyro was as scary as ever. Bizarre! Power of the Gammaizers!

The Dream World

Empty! World of Dreams! Real Worth! Merriment Power!

Pursuing Honami

Furious! Idol's Declaration! Learn! All the Ways!

Interest in the Gammaizers

Igor overheard Adel's conversation with a Gammaizer and desperately asked him what kind of power he searches for. When Alia came in, she ordered Igor to leave but Igor refused. He finally left after Alia slapped his face (the same way Akari does). After seeing Alia's defeat as Dark Necrom Pink and her shattered Eyecon absorbed by Gammaizer Magnetic Blade, he found it very interesting. Later on, Igor, along with a Gamma Superior and a Gamma Ultima, stopped Ghost Mugen Damashii from interfering with Gammaizer Magnetic Blade. They retreated after Deep Specter backed up Ghost. After that, they faced Ghost Mugen Damashii, Deep Specter and Necrom for a second round. Igor was defeated by Ghost Mugen Damashii's Shinnen Impact and as a result, his Gamma Superior Eyecon was destroyed. Opposition! Father & Daughter!

Courage! Tragic Resolution!

Igor learns that Edith has been banished.

Igor was most pleased to discover that the magistrate, Edith, had been banished by Adel, voicing that, with the nuisance of Edith gone and the Demia Project nearing completion, his time was coming. Upheaval! The Magistrate's Decision!

Connect! Genius Juvenile!

Activate! Terror of Demia!

Horrible! Disappearing World!

Duel! Words from the Swordsman!

Igor appears with an army of Gamma Commandos and Gamma Superior to take down Takeru and his friends. After Akari slaps Igor out of Adel's mind control, a Gamma Commando appears to take down Akari and Onari. Igor takes the hit and his Eyecon body is destroyed. Gather! Chain of Grief!

In the end, Igor has awakened from the life support capsule. Infinity! Power of Humanity!

Igor is possessed by the Grimms in the stage show and assumes their Kamen Rider Necrom form. Kamen Rider Ghost: Final Stage


Igor is a Gamma scientist whom values his study greatly and debunks any kind of supernatural presence, making him as a Gamma counterpart to Akari. Like most Gammas, he also has a great sense of disgust towards humans and sees their lives "invaluable".

Behind the scenes


Igor is portrayed by Hiroshi Yamamoto (山本 浩司 Yamamoto Hiroshi). As the Gamma Superior, his suit actor is Yuya Nawata (縄田 雄哉 Nawata Yūya), Hajime Kanzaki (神前元, Kanzaki Hajime), Masashi Takada (高田将司, Takada Masashi), and Toshihiro Ogura (おぐらとしひろ, Ogura Toshihiro)


Igor's name comes from a hunchbacked stock character from the classic Universal Monster horror movies. The character originally was named Fritz in the 1931 film classic Frankenstein, but the character's name was later changed to "Ygor" and then "Igor" in later Frankenstein films. Despite popular belief, there was no Igor or lab assistant in the original 1818 novel by Mary Shelly.

Concept Art

Gamma Superior was designed by Kazuhiko Shimamoto (島本 和彦 Shimamoto Kazuhiko).


  • The first letters of the three Gamma Eyecons Igor uses (Knife, Machine Gun, Seiryuto) also make out "KMS", his nickname.
  • Igor was the third Gamma to use a Damashii, with the first being Denki Gamma, followed by Alain as Kamen Rider Necrom. But nonetheless, he is the first to use it in his Gamma form the same way the Ghost Riders do so.
    • Igor is also the second monster of a series to use both the respective Rider and its monster counterpart's collectible devices, following Roidmude 027.
  • When Igor transform into some Gamma forms such as Machine Gun, Seiryuto, Book, and Onpu, his Proto Mega Ulorder disappears. This can be attributed to production convenience; as these Gamma's Parkas have long sleeves, the Proto Mega Ulorder would naturally be hidden within the sleeve, as such, the Proto Mega Ulorder prop is not worn on the Gamma Superior suit during production when these Gamma forms are used.
  • His ability to transform and channel the powers of defeated Ganma is similar to Kou Tatsugami/Leo Zodiarts from Kamen Rider Fourze, who was able to transform and channel the power of defeated Horoscopes.
