Kamen Rider Gatack
Kamen Rider Gatack is one of the main protagonists of Kamen Rider Kabuto. The motif is of a "Kuwagatamushi" or stag beetle. The name is a pun on "kuwagata" (as in kuwagata-mushi, the Japanese word for "stag beetle") and "attack". Its primary user is Arati Kagami. Kagami is a field agent of ZECT who also works with Hiyori at Bistro La Salle. A 21-year old man. He 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 by killing all Worms. He was later confronted by the Worm that had killed and mimicked his brother, but could not bring himself to kill him, only to watch as Kabuto killed the Worm himself. 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 wounded Shadow members. Kagami, 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 realised that Tendou 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. His father is secretly a high ranking member of ZECT, but Kagami is seemingly unaware of this. Despite being only a field agent, he frequently takes on Worms armed only with his standard-issue collapseable pistol, or picks up a Machine Bladegun from a fallen ZECT Trooper. It's interesting to note that he's the first ZECT Agent to kill a worm on his own (by impaling it with the Blade part of a Machine Bladegun on one occasion, and once with "Clocked-Up" help from Kabuto on another, which lead to a brief moment of bragging and re-telling the events which took place repeatedely, albeit with some exaggerations made) and motivated other ZECT Troopers to join in.
- Device Type: Rider Belt ('Henshin' Belt)
- Animal: Stag Beetle
- Color: Blue
- Cast Off System: The mandible-like levers of the Gatack Zecter are switched over to the right.
- Cast Off Announcement: "CHANGE STAG BEETLE!!!"
- Clock Up System: Waist pads on the belt
- Primary Finisher: RIDER KICK - Gatack presses the charge button on the Gatack Zecter thrice and switchs its mandible-like levers back to its default position. The power charge begins once the Gatack Zecter's mandible levers are switched over again to the "Cast Off" position. The charge sent to Gatack's right leg is used in a flying roundhouse kick to the Worm's head; obliterating it. (This attack is similar to Kabuto's Rider Kick off the Kabuto Extender.)
- Secondary Finisher: RIDER CUTTING - Gatack's alternative attack via the Double Caliburs' scissor configuration to clutch his adversary and split them in two; the power charge begins automatically, allowing Gatack to initiate the attack almost immediately.
Although he is given a chance to test the Gatack Zecter, he was attacked by the Zecter which rejects him. But when Kagami goes to rescue the young boy Makoto, whom he met in the warehouse, Makoto's true form is revealed to be Tarantesworm. Tarantesworm kills Kagami and leaves quickly. After the Worm leaves, an unknown man appears and equips Kagami's lifeless body with a Zecter belt. Kagami then revives due to the capability of the Gatack Zecter and becomes Kamen Rider Gatack. Kagami goes on to fight the Tarantesworm 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 "naïve 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. The voice of Gatack Zecter differs from the other Zectors. He decides to work together with Misaki and Tadokoro to find out the truth of Masked Rider Project after he confronted Mishima. Gatack will leave Kagami at the episode 31.
