List of Kamen Rider Kabuto characters

Kamen Rider Kabuto (仮面ライダーカブト) is a Japanese tokusatsu series that serves as the 16th installment in the Kamen Rider franchise and the seventh entry in the Heisei era. These characters play a major role within the series and often influence many key events.

Souji Tendou
Souji Tendou (天道 総司), real name, is a wild card and possessor of the Kabuto Zecter (カブトゼクター), which he acquired on the day of the meteor along with the Rider Belt (ライダーベルト) from a version of himself from an alternate future. This played in Souji having a sense that is meant for greatness that makes him initially appear arrogant but is very compassionate. He often seems to follow monk-like philosophies of peace, using the kanji in his full name to in his formal instruction: "The man walking the path of Heaven, and will rule everything." (天の道を行き、総べてを司る男) or quoting amazingly appropriate zen-like phrases he supposedly learned from his grandmother. Having no job or college education despite being very talented, Souji normally stays home with Juka before becoming a regular customer at Bistro La Salle after meeting Hiyori Kusakabe, whom he recognizes as both the girl he saved and a Native Worm whom he considers his little sister. This played in his ability to recognize Worms in disguise merely fights for his own needs to wipe the aliens out and provoking ZECT as a result. After defeating the Worms and ZECT's corrupted higher ups, Souji leaves Japan to travel to France.

As Kamen Rider Kabuto, he is usually in his pupa-like armored Masked Form (マスクドフォーム) before using the Kabuto Zecter's Cast Off (キャストオフ) command to assume the sleeker and more combat-oriented Rider Form (ライダーフォーム) which uses the Clock Up (クロックアップ) ability to travel at near-light speeds to match the speeds of the Worms or for Kabuto to perform his tachyon-powered Rider Kick (ライダーキック) finisher. Both forms use the Kabuto Kunai Gun (カブトクナイガン), a sidearm that has a Gun Mode (ガンモード) for performing the Avalanche Shoot (アバランチシュート) finisher, an Axe Mode (アックスモード) for performing the Avalanche Break (アバランチブレイク) finisher, and a Kunai Mode (クナイモード) for performing the Avalanche Slash (アパランチスラッシュ) finisher, and the Kabuto Extender (カブトエクステンダー), a modified Honda CBR1000RR able to change from Masked Mode (マスクドモード) to Ex Mode (エクスモード).

Kabuto later acquires the Hyper Zecter (ハイパーゼクター), a Zecter made by ZECT in the future, which enables him to assume Hyper Form (ハイパーフォーム) by using the Hyper Cast Off (ハイパーキャストオフ) command. As a stronger version of Rider Form, Kabuto is capable of using the Hyper Clock Up (ハイパークロックアップ) ability to move at great enough speeds to potentially travel seven years through time as well as to perform his Hyper Kick (ハイパーキック) finisher. He also acquires the Perfect Zecter (パーフェクトゼクター), which can switch between Sword Mode (ソードモード) and Gun Mode. By increasing the Perfect Zecter's power with the TheBee, Drake, and Sasword Zecters, he can perform one of two finishers: Maximum Hyper Typhoon (マキシマムハイパータイフーン) via Sword Mode or Maximum Hyper Cyclone (マキシマムハイパーサイクロン) via Gun Mode.

Having joined ZECT to avenge his younger brother Ryou Kagami, works with Hiyori at Bistro La Salle, Arata has a good heart but is impulsive often acts without thinking. In the previous timeline, Kagami married a Hiyori Kusakabe before helping Souji alter the timeline so the damage caused by the Worms' meteor would be minimized in Shibuya. In the new timeline, Arata meets Souji all over again when the latter claimed the Kabuto Zecter that he was to upon its completion. Being the only member of ZECT to know Souji's identity as Kabuto, momentarily using TheBee Zecter after Yaguruma was relieved of his duty, Arata became torn between his duty to ZECT and seeing Souji as a friend.

Arata eventually acquired the Gatack Zecter (ガタックゼクター) and, becomes Gatack in the current timeline while learning the truth behind ZECT. They managed to wipe out most of the Worms before helping the rebels against the compromised ZECT led by Masato Mishima and the Native-class Worm leader Negishi. After ZECT was defeated, Arata started a new life with his father in the police force. During the events of Kamen Rider Zi-O, learning he is one of the few to remember ZECT and the Worms due to a time distortion, Arata helps the titular protagonist prevent a new Worm invasion while representing Souji.

As Kamen Rider Gatack, he is usually in his Masked Form equipped with the twin shoulder-mounted cannons, which possess a shooting radius of 1 kilometer, before using the Gatack Zecter's Cast Off command to assume Rider Form where he gains access to the Clock Up ability and dual wields a pair of  shotels, consisting of the gold-colored Plus Calibur (プラスカリバー) and the silver-colored Minus Calibur (マイナスカリバー), which he can combine into a scissors-like weapon for his  finisher.

She believed that they were murdered by a person wearing a Rider Belt, but after a period of uncertainty she concludes that Souji, despite owning the belt, would never do something like that. After seeing Gatack wear another belt and discovering that he was Arata, she also began to doubt him. In the end however, she decides to trust both of them as they have helped her so much. She carries a green crystal that originated from Area X, ground zero of the meteor crash. She seems to be able to talk with and read the emotions of inanimate objects, such as drawings and machines. She's quite clumsy and tends to zone out while working, resulting in complaints by customers. Through several mishaps and accidents, she was able to discover the identities of all the Riders besides Drake. Later in the series, it was discovered that Hiyori is the child of a Native Worm who impersonated Souji's mother down to her pregnancy, and later gave birth to. This technically makes her Souji's younger sister. During episode 33, the energy charge from the Hyper Zecter sent her along with the Souji Kusakabe to the edge of time and space. The Hyper Zecter later appeared in the normal dimension, showing one of Hiyori's drawings to Souji and Arata.

She returns to the real world in episode 43 to defend Dark Kabuto from Hyper Kabuto, stating that she no longer desires to live in the human world. Ultimately however, after a compelling speech by Tendou saying that she will not be hated in the human world, even though she is a Worm, she abandons Kusakabe Souji and returns to the human world. However, she is then attacked by Dark Kabuto. After being saved by Tendou, she returns to an almost normal life, and begins making her own menu and dream of owning a restaurant come true.

She has different ways of saying "Good Morning" to Souji and loves his cooking. Lately, she has been targeted by ZECT and the Worms.

However, the Scorpio Worm's mind was completely overridden by the real Tsurugi's memories, believing himself to be Tsurugi while haunted by Mika's death to the point of disassociating himself as a Worm while vowing to kill them all. Jiiya kept Tsurugi in the dark of his true identity as the Kamishiro fortune had severely dwindled, Tsurugi becoming ZECT's hired exterminator as.

But this would turn out to be Tsurugi's plan to fulfill his promise by leading the Worms to slaughter, allowing Souji to fatally wound him with the Maximum Hyper Typhoon so Mika can be avenged before returning to his mansion to die in peace.

He tells Arata about Tsurugi's sister and her death at the hands of the Scorpio Worm. He has a younger twin brother who keeps the Legendary White Knife.

However, she was still irritated by Souji when he implies that she and Arata make a cute couple. She used herself as bait by disguising herself as Phantom Thief Shadow and tended to Arata when the Gatack Zecter attacked him. She loves buckwheat soba, and can chow down entire ramen bowls in seconds. A Worm disguised as her was sent to attack Souji's sister, but ended up meeting Tsurugi.

He is a highly trained fencer and plays the cello. It seems that he has a very secret agenda and would even sacrifice his sons to achieve his goals. Souji later confronted Riku; the confrontation ended with Riku telling him that Souji's sister (actually refers to Hiyori, not Jyuka) was not in good hands, which naturally made Souji lose his composure, and Riku walked off, joking about Souji's "walking down the path to heaven to rule over all".

Souji went out of the way to make sure she would be well fed. She was also the person that booted Shun out from the ZECT HQ. Afterwards, Mishima orders her to kill Souji, but Souji presuades her to forget Mishima and help him steal the Hyper Zecter. She is eventually knocked over the building by the Uca Worm only to be saved by Souji. Despite her sweet and innocent demeanor, she is a fearsome fighter armed with a wire which can cut through almost anything; however, she is still relatively weak against Worms, but tries to fight anyway. After accepting Souji as her superior, she began to work at the Bistro la Salle, although she often misinterpreted recipes and created horrible dishes as a result. Due to her harsh bring up as a BrighTrooper, her perception of training is rough. This was seen in Episode 38 when she began to time Jyuka and her classmates in setting up tents before their camping field trip. She was hit by a bullet that ricocheted off Kabuto's Kunai Gun, but hitting her in the shoulder.
