1 2 "The man who washes his face in front of mirror everyday." ―Tendou's translation of Kagami's name.[src] "The deity of war, Gatack's chosen one, Arata Kagami!" ―Daigo's words as Tendou and Kagami protect him[src]

Arata Kagami (加賀美 新, Kagami Arata) is Kamen Rider Gatack (仮面ライダーガタック, Kamen Raidā Gatakku, Masked Rider Gatack), one of the main protagonists of Kamen Rider Kabuto. He was previously the second user to become Kamen Rider TheBee (仮面ライダーザビー, Kamen Raidā ZaBī, Masked Rider TheBee), but later decided to not fight Kabuto and gave up TheBee Zecter.

History

He started out a low-level field agent of ZECT who's responsible for filming battles. He also works with Hiyori at Bistro La Salle. He has a good heart but is hot-blooded and will often act without thinking about the repercussions of his actions. During the first episode, Kagami attempted to become Kabuto with a Rider Belt but failed as the Kabuto Zecter had chosen Tendou. He joined ZECT in order to avenge his younger brother who was killed by Worms.

He was later confronted by Bellcricetus Worm, the Worm that had killed and mimicked his brother, Kagami could not bring himself to kill the Worm as he thought it would be killing the last remnants of his brother. Kabuto would also not kill the Worm until Kagami made the choice to allow him to kill the Worm. Kagami was later chosen by the TheBee Zecter to become Kamen Rider TheBee after it rejected the previous user, Sou Yaguruma, and reacted to his desperation to protect the wounded Shadow members. Arata, however, gave up his role as TheBee after he was torn between the orders of ZECT to eliminate Kabuto and his budding friendship towards Tendou.

He later realized that Souji did not want a friendship with him—after accepting this fact and renewing his pledge to destroy all Worms, Tendou let him back into his life. He was later framed by Shun Kageyama as being a traitor to ZECT, but this was simply to lure the real traitor out. He would have died if Tendou had not saved him. This incident ignites Kagami's will to destroy Worms on his own.

Although he is given a chance to test the Gatack Zecter, he was attacked by it when it rejected him. When Kagami goes to rescue the young boy Makoto, whom he met in the warehouse, Makoto's true form is revealed to be Tarantes Worm, who kills Arata and leaves quickly. After the Worm leaves, a mystery man appears and equips Kagami's lifeless body with a Zecter belt. Kagami then revives due to the capability of the ZECT belt's energy field. Later, Kagami calls upon the Gatack Zecter and goes on to fight the Tarantes Worm only to be saved by him in the end by shielding him from the explosion detonated by the Shadow Troopers. This convinces him that Worms have a humane side to them; but is mocked when Kabuto tells him he's "naive as usual." Gatack tells Kabuto that he is who he is and nothing can change that. His design looks similar to Kabuto's except he has mandible horns and is colored blue with red eyes. The voice of Gatack Zecter differs from the other Zecters. He decides to work together with Misaki and Tadokoro to find out the truth of the Masked Rider Project after he confronted Mishima.

During a battle, Kagami discovered the true identity of Tsurugi Kamishiro (Kamen Rider Sasword). After seeing Tsurugi's devotion to avenge his sister, Arata decided to protect Tsurugi. This eventually caused a fight between Gatack and Kabuto to prevent Kabuto from killing Tsurugi. After this, Arata and Tendou witnessed the transformation of Hiyori to a Worm. Despite her being a Worm, Arata works together with Tendou to protect her. But their results end in failure as Hiyori disappears with the man in the iron mask. This incident leads Souji into joining ZECT in order to destroy it from within and also starts collecting Zecters. Arata does not believe in Tendou's method of collecting all the Zecters so he can save Hiyori. This eventually sparks a furious fight between Gatack and Kabuto, which Gatack ends up losing. Tendou wants Kagami to give up the Gatack Zecter but Kagami refuses, stating that Riders are meant to protect humans. Arata is seemingly destroyed by Cammarus Worm in episode 34, but he is saved when Hyper Kabuto uses the Hyper Zecter, although unsure of its function, to reverse the flow of time and save his life. Even after this Souji still told Arata that they will fight one day to finish things.

Kagami is told by the ZECT HQ to protect Daigo Tachikawa at first, but Arata soon discovers he is a Worm, but realizes then he realizes again that Daigo is not a Worm that destroys humans. Arata later finds Daigo again, this time taking him to Tsurugi's house to heal him. However, after the short confrontation, Daigo realizes Tsurugi is a Worm and uses the Sasword Zecter to escape from him. Arata was referred to by Tachikawa as "Arata Kagami, the one chosen by the god of battle". This was also shown in the report found at Area X. During the battle with Cochlea Worm, Kabuto’s Red Shoes System activates, which leaves Gatack alone to try and stop him. Ultimately succeeding, they are attacked by the Hopper Riders shortly after and are defeated horribly. In the end however, Arata and Souji make a promise with each other, if Souji goes berserk again and tries to kill Hiyori, Kagami will kill him, vice versa. Souji also no longer wants to own the Gatack Zecter, for no one would be able to stop him if Arata were to ever disappear.

Arata's suspicions about ZECT begin to grow during episode 41 when they unknowingly escort a group of Natives. When they are attacked by a group of Salis Worms, the Natives attempt to escape, referring to Gatack as "The Top's son". Confused, he is the first one to meet Reiji Nogi, the executive class Worm that was able to defeat him in one attack. Arata then goes to his father, and he tells him the origin of ZECT. Arata discovers that the Natives came to Earth 35 years ago and made an agreement to help create the Masked Rider System. In turn, ZECT would help protect the Natives against the Worms that would arrive later. His father tells him that his soul now belongs to the Natives, and Arata needs to be the one to carry it on. After hearing this, Arata begins to fear that his sole existence is to be the catalyst for defeating Worms. Arata's faith is further shattered when he discovers Tadakoro is a Native, thanks to the accidental exposure of AMB (Anti Mimic Bomb) gas. Shocked and dismayed, Arata continues to wonder about why Tadokoro hid this secret, and so he is unable to fight.

In turn, he is defeated by both some Salis Worms and Nogi in a matter of minutes. Arata is eventually led off by Misaki, but he is still angry at Tadakoro for hiding the fact that he is a Native. During episode 42, Arata is chosen as the negotiator to rescue the Natives. Nogi has demanded that ZECT give up their last AMB and they will release the Natives, along with Tadakoro. Arata, still angry at ZECT refuses and even gives up his Gatack Buckle. However, after Souji talks to him, he realizes that his father wanted him to save the Natives, but at the time keeping the AMB. Realizing that he needs to catch his father's feelings, Arata goes and meets Mishima, taking the AMB from him . Through trick and trap, they are able to rescue the Natives and protect the AMB, although Arata is once again defeated by Nogi. Souji arrives on the scene and displays his new power as he uses the Perfect Zecter Gun Mode to defeat Cassis Worm Dimidius.

After patching things up with Tadokoro, Arata once again has a brighter outlook on life. While playing again at the baseball field, Arata meets his father again, who shows that he does indeed love Arata and plays catch with him. In turn, Arata is finally able to accept his father's feelings. Soon after, Arata meets Cassis Worm Gladius in battle, and his Rider Kick attack goes horribly wrong, with the kick being returned against Arata. It is later discovered that Gladius and his Worm army are planning to assault Area Z, the place where the original Masked Rider System was created.

After leaving the Hospital, Arata discovers that Souji is planning to lose to Dark Kabuto in order to find Hiyori's whereabouts, and immediately finds Tendou, shouting the sense back into him. Despite this, Souji states that he cannot fight for Hiyori anymore, as she is happier with the fake. Arata however, believes that Hiyori is trying to protect Souji, and tells him that he needs to go after her. After Souji leaves for Hiyori's world, Arata goes on to fight Cassis Worm. He meets Shun who has once again become TheBee, but their attacks fail, and Nogi defeats them once more. Arata is able to return to the battle before Tadokoro detonated Area Z. Gatack, Kick Hopper, and Kabuto then execute a three-way Rider Kick, effectively neutralizing Cassis Worm who was then destroyed by Hyper Kabuto.

Gatack is called upon to fight the Worms that are constantly appearing, but he is sidetracked after discovering that Misaki has agreed to Tsurugi's request for a date. Unwilling to tell her that Tsurugi is a Worm, he follows them on their date, only to discover that Tsurugi does indeed lose control, forcing Arata to save Misaki.

Despite this, both Tsurugi and Misaki end up being completely infuriated at Arata. Misaki is astonished that Arata knew all along Tsurugi was a Worm, but never told her. Tsurugi is mad at Arata for similar reasons, that even though Arata knew all this, he never told him. Arata finally tells Souji of Tsurugi's true identity later, but still believes that he isn't entirely evil. Souji on the other hand, decides to defeat him, as with all other Worms. After rushing off to meet Clipeus once again, Scorpio Worm rises from the sea and assaults Arata. Arata, unwilling to fight his friend, gets defeated. Meeting Tsurugi again, Arata tries to convince him to live as a human again, handing him Misaki's present. However, Tsurugi punches Arata out instead, and takes the Gatack Zecter. Kidnapping Arata, Tsurugi attempts to destroy all the Zecters, but fails as Arata and Souji are able to regain their Zecters. While Souji goes to fight Scorpio Worm, Arata takes on one of the Clipeuses, effectively defeating him with a Rider Kick.

Arata's father Riku has finally announced to the world, saying that the Worm threat is finally over. Arata is given the task of delivering the necklaces that can warn humans when a Worm is near. However, he meets conflict in Souji when Souji states that there is something desperately wrong with the device. After multiple conflicts, Arata is finally able to confront Souji, but Souji escapes, and only leaves an injured Renge behind. This leaves Arata, Todokoro, and Misaki even more furious at Souji for his unexplainable actions. Later on, Arata encounters Souji once more and demands to know his reasons for destroying the necklaces. Souji states that they are turning humans into Natives; not believing this, Arata and Souji do battle. With the help of the ZECTroopers, Kabuto is defeated. After defeating Kabuto, Arata receives a call from Misaki, telling him that Mishima has taken over ZECT. Arata then goes to rescue his father, who tells him that no matter what, he must believe Kabuto and fight alongside him.

During the final stage, Arata finally realizes that the necklaces, along with Mishima's broadcast signals, are changing humans into Natives. After knowing Mishima's evil plot, Misaki and Tadokoro aided him. Arata confronted Mishima and Negishi, only to be defeated by Mishima and is almost killed, until Souji arrives on the scene. Arata realizes that they are the only ones who can save the world now, and must do it no matter what. Together with Hyper Kabuto, they are able to destroy Mishima, thus ensuring the safety of the world. Within his last moments, Mishima collides with the meteorite, setting off an explosion and ruining their entire operation.

After realizing the battle is over, he removes the Gatack Zecter, and letting it go, watches it fly away with the Kabuto Zecter to an unknown destination. Arata then falls to the ground with exhaustion, and as he is relaxing smiles, realizing the battle is finally over. After hearing Souji`s words and finishing it for him, Tadokoro, Misaki, and Renge arrive. Misaki gives a hug to Arata. Renge does the same to Souhi, giving both great surprise. Tadokoro stands to the side and smiles in victory.

During the epilogue, it is shown that Arata now lives a normal life as a police man, with his father still watching over him. As he is crossing children across the street, a young girl asks him, "Where did the man who walks Heaven's Path go?" Arata smiles and replies that Souji is currently out buying tofu. Arata then looks to Souji's house which he and the girl are standing in front of them at the sky in wonder.

Personality

Arata is quite rash and hotheaded, as shown when he takes the Kabuto bike to fight against Worms only for it to be taken away by Tendou and nearly gets himself killed for trying to use the Gatack Zecter. He easily gets annoyed, mostly because of Tendou's personality or when ZECT HQ gives absurd orders for him and his team. In addition, he is also quite naive, as he easily believes in the fact the mimicked Ryo (his younger brother who goes missing two years before but suddenly returns) and Makoto (a boy who is trapped in an abandoned factory full of Worms) are not Worms but real people. As a result, he nearly gets himself killed by Worms on more than one occasion. However, in Makoto's case, his belief may not be without merit, as the Worm actually does shield him and protect him from an explosion.

Aside from that, Arata is essentially a good-natured person at heart, always willing to try his best to save people from the terror caused by Worms. He is amiable and supportive to all his friends, especially Tendou and Hiyori, and will never hesitate to help them once the need arises. In fact, the reason why he wants to become a Kamen Rider is to defeat all Worms that threaten humanity and to avenge his brother Ryo. When he does become a Kamen Rider, he takes his duty very seriously, proving himself to be a valuable asset and ally to the protagonists.

Another trait of Arata's is his determination. During the time period when he's rejected by the Kabuto Zecter, he never backs down on his duty to fight and kill the Worms. Even though he is outperformed (for a while) by the other characters, he is still more than willing to take up arms on his own to fight and protect humanity.

Fighting Style

Despite being only a field agent, he frequently takes on Worms while being armed only with his standard-issue collapsible pistol. It is interesting to note that he is the first ZECT Agent to kill a Worm on his own by impaling it with the retractable bayonet of a Machine Bladegun on one occasion.

When fighting as a Kamen Rider, Kagami's fighting style largely involves brawler-type moves, frequently tackling his enemies and opting for rapid punches and kicks. As Gatack, his fighting prowess becomes more and more refined as the series progress, becoming a formidable foe to any Worm that he comes across. He makes full use of his Gatack Vulcan and Double Calibur in battle, shooting and slicing Worms in quick succession. This, combined with ClockUp, allows him to defeat swarms low-class Worms with little to no effort at all.

Forms

Kagami was the second user chosen by TheBee Zecter to become Kamen Rider TheBee. Later, he was chosen by Gatack Zecter and became Kamen Rider Gatack. In 2019, he was chosen by the Kabuto Zecter and became Kamen Rider Kabuto.

• Riku Kagami - Father
• Ryo Kagami - Younger brother

Relationship

• Allies:
  • Souji Tendou: At first, he considers Souji a weird person and gets annoyed by his personality but later wants to befriend him. Although their relationship has a rather rocky start in the beginning due to their differences, they eventually become great friends, with Tendou even noting that their bond is unbreakable during their fight with Cassis Worm. The two share a mutual trust and dependence on each other. Tendou helps Arata when he's in doubt, and Arata convinces him to fight Dark Kabuto instead of giving up. On a side note, Tendou believes that Arata should be the one to defeat him if the Red Shoes System makes him go out of control. 
  • Yuzuki Misaki: Yuzuki is the most trusted ally on his team. Like Tendou, she is also usually shown giving Arata advice when he is in a dilemma. 
  • Shuichi Tadokoro: Arata's superior who cares greatly about his subordinates. Arata looks up to him, but he loses all of his respect when it is revealed Shuichi is a Native. However, they are able to set aside this difference eventually and become good partners again
  • Hiyori Kusakabe: Arata's coworker at the Bistro La Salle. The two share a close relationship. In the movie's timeline, it is revealed that he is in love with her.
  • Jyuka Tendou: He befriends Jyuka despite Souji's reluctance of having Jyuka as his friend. He also cares about Jyuka like his own sister.
  • Yumiko Takemiya: His boss at the part-time job. There are times when she helps Arata get closer to Hiyori.
  • Daisuke Kazama: Arata thinks of him as weird as Souji. They do not share a close relationship, only appearing together when fighting Worms most of the time.
  • Tsurugi Kamishiro: Tsurugi considers Kagami his great friend, and wants the best of things to happen to him. Kagami, however, cannot muster enough courage to reveal the truth that Tsurugi is actually Scorpio Worm all along to the millionaire, because he is afraid that it may hurt Tsurugi. 
  • Jiiya: Jiiya trusts Arata enough to tell him about Tsurugi's biggest secret. The two are usually seen discussing what to do with Tsurugi.
  • Renge Takatori: At first, Arata and Renge have a very bad relationship. Arata dislikes her childish attitude while Renge dislikes Arata for being a clumsy senior. Later on, Renge begins to respect Arata more, particularly during the School ghost incident, when Arata tries to cheer up students when they are trapped in a bus shrouded with mist, which has been caused by a Worm's attack.
• Family:
  • Riku Kagami: Arata at first shows animosity towards his own father because of his nonchalance at the death of Ryo Kagami, his second son. After learning what his father has been through all the time, Arata finally understands the responsibility and love of Riku, and they become close once more. They are even seen playing catch with each other as adults on one occasion.
  • Ryo Kagami: Arata cares about and loves his younger brother greatly. This even makes him reluctant at letting the Worm that mimicked his brother be destroyed.
• Enemies:
  • Masato Mishima: Initially, the two dislike each other because of their difference in personality. In the final stages of the series, when Mishima becomes the last obstacle, Arata is determined to finish him off for good. Mishima admits in the final episode that he has always hated men who are "straight as an arrow" like Arata.

Behind the scenes

Portrayal

Arata Kagami is portrayed by Yuuki Sato (佐藤 祐基, Satō Yūki). As Kamen Riders Gatack and TheBee, his suit actor was Makoto Ito (伊藤 慎, Itō Makoto).

Notes

• The motif of Gatack is that of a "Kuwagatamushi" or stag beetle as opposed to Kabuto whose motif is that of a rhinoceros beetle.
• He is one of two Riders whose Masked Form provides additional offensive capabilities, the Gatack Vulcan, in addition to increased defense, the other being Sasword's Blood Vessels.
• The name is a portmanteau of "kuwagata" and "attack" forming Gatack​​, which ironically would foreshadow who he would be after abandoning TheBee Zecter.
• Gatack's Hyper Form is exclusive to the series' Hyper Battle DVD. Unlike Kabuto, whose armor experiences a major remodeling upon transforming, the changes from Gatack to Hyper Gatack are minimal, only changing his helmet and adding a Tachyon breastplate, which does not open up during Hyper Clock Up. Gatack gains no new weapons or capabilities as Hyper Gatack beyond the use of Hyper Clock Up and a Hyper Kick, though he retains the use of the Gatack Calibur.
• Gatack is considered the Secondary Rider of Kabuto despite being the fifth Rider seen in the show. This is probably due to his frequent appearances in the series especially with the main Rider, as well as his theme (Kuwagatamushi), which is often portrayed as the "counterpart" of Kabutomushi.
  • It is also noted that the opening of Kamen Rider Kabuto started to update after Gatack started his debut, the tradition that always be done to any Kamen Rider's opening video whenever the second rider started to appear late in the show.
