Worm (Kamen Rider)

From Wikipedia, the free encyclopedia

Worms (ワーム Wāmu) are the villains in the Japanese tokusatsu series Kamen Rider Kabuto. They are an alien life form that came from a meteor destroying the city district of Shibuya seven years prior to the series' timeline. However, the Worms known as Natives existed prior to the coming of the Shibuya Meteorite, through another meteorite that came 35 years ago. In the movie, a third meteor nearly hit the Earth, though thanks to Kabuto it was adverted and history was altered. This implies that meteors containing Worms are insolated and there are others.

The Worms were designed by Yasushi Nirasawa (韮沢 靖 Nirasawa Yasushi), who also designed the Undead for Kamen Rider Blade, the Horrors in GARO and later created the Imagin for Kamen Rider Den-O. These designs were later detailed in Worm Works: GITAI (ワームワークスGITAI Wāmu Wākusu GITAI).[1]

Shibuya Meteorite[edit]

A mysterious meteorite that crashed into Shibuya seven years ago. This meteorite brought along the extraterrestrial creatures known as Worms. During episode 41, Riku Kagami explains that another meteorite carrying the Natives had arrived on Earth thirty-five years before this, explaining why fragments of the meteorite similar to those of the Shibuya Meteorite existed so long ago. The Natives that arrived on Earth worked with humans to create the Masked Rider System in order to fend off the threat of other Worms that would arrive later. In the movie, which acts as a prequel to the series, it is revealed this meteor was actually far larger and would've vaporized Earth's oceans and released many more Worms until Hyper Kabuto went back in time with the meteor and caused it to slam into the Shibuya meteor, resulting in only a small fragment of it landing in Shibuya.


There exist two different species of Worms, the Natives and the unnamed Worms. The Natives have a horn appendage attached to their heads and they are not as aggressive as the Worms.


Natives are the Worms that arrived on Earth 35 years ago. After assuming human identities, they developed the Masked Rider System to give to the humans what would form ZECT. In return, ZECT would protect them from other Worms that might arrive. Most usually live in peace blending in with human society; some actually can create their own human forms without stealing other identities compared to their counterparts. Hiyori is "unique" among the Natives because she was naturally born Native.

Tachikawa Daigo is the first Native to appear. Certain Natives like him are able to summon the power of the Zecters. More Natives are revealed during episode 41, as their alliance with ZECT is clarified. Tadokoro is also revealed to be a Native working for ZECT after an AMB accident forces him back into his Worm form. Sisyra Worm, a Worm that was born from a Native mother, is the only Native Worm to be shown outside of a pupa form.

Negishi, a leader of the Natives who appears in episode 45, seems to be very hyperactive. In episode 47 and 48, it is revealed that Negishi works together with Mishima in order to turn humans into Natives using a special necklace, as Negishi believes that there is no other way for his kind and humans to co-exist. However, some Natives, such as Tadokoro, are indeed able to live on as a human. Ultimately, Negishi's plan fails thanks to Kabuto and Gatack. At the end of the series, it is assumed with the final destruction of the invading Worms, the Natives return to their previous peaceful co-existence with mankind.


The second Worm species, they are not given a specific name, arrived on Earth seven years ago on the Shibuya Meteorite. Aggressive to humans, Worms attempt to blend into the human population by copying the faces of their victims along with their memories. They only need to look at the human to copy their image, but once done so, they attempt to kill the original. However, the Worms believe the person that was mimicked now exists as a part of them due the fact they also acquired their victims' personalities. Despite being able to copy both image and memory, they are unable to copy certain things such as scent; in addition, their disguises can be neutralize by chemicals, such as makeup. Aside humans, the Worms are extremely aggressive towards their Native counterparts. The pupa form is known as a Salis Worm (サリスワーム Sarisu Wāmu), taking on the shape of a chrysalis. A Salis normally has a green body, except for the albino one known as a Mutation Salis (ミューテーションサリス Myūtēshon Sarisu) which has a white body. After a Worm is threatened or endangered, it has the ability to molt, revealing a stronger form that can move at blinding speeds which comes from their high metabolism.

It is later revealed that Worms do not need to naturally molt and their "cast" can be broken off or shattered. They also have the ability to revert into a Salis form if necessary. They tend to evolve more efficiently than their counterparts. When a Worm is destroyed, it explodes into its predominant color. They largely resemble Arthropods, specifically insects. The Executives and their direct subordinates are the only Worms with non-insect appearance. Rena Mamiya/Uca Worm, Cammarus Worm, Subst Worm and Reiji Nogi/Cassis Worm are all crustacean-type Worms. The Cochlea Worm is surprisingly a mollusk. By the events in episodes 46 and 47, the Worms eventually die out with only few remaining.

Major Worms[edit]

Playing a significant role in the series, these Worms are usually Executives or otherwise important Worms that greatly influence the story.

Worm Class[edit]


The upper-class Worms usually control massive groups of Worms. Very few Executives have been seen, but they each possess an enormous amount of power.

  • Uca Worm (ウカワーム Uka Wāmu, 25-40): The first executive leader Worm to appear during episode 25, assuming the form of Rena Mamiya (間宮 麗奈 Mamiya Rena), a woman whose childhood dream was to sing in an opera. As a result, Uca Worm had an interest in singing requiems to her victims. She has several subordinates as her followers. Three of them (Cammarus Worm, Cochlea Worm and Subst Worm) are shown in their Worm form. The two remaining subordinates only appear in their human form during episode 37, testing Tendou's ability to fight without the Hyper Zecter. Instead of being defeated at the hands of the Hyper Zecter, they were destroyed by Tendou's newly acquired Perfect Zecter. During the events of episode 39, in a fight with Kabuto, Uca Worm was injured and suffered a loss of memory as a Worm, believing that she was Rena herself and meeting Daisuke who fell in love with her human side. However, Rena soon regains her memories and fights Drake, forcing him to fatally wound her with (Double) Rider Shooting. Shortly afterwards she dies in Daisuke's arms.

  • Cassis Worm (カッシスワーム Kasshisu Wāmu, 41-46): An even stronger executive leader Worm, entering the scene after Uca Worm was destroyed. He assumes the form of Reiji Nogi (乃木 怜治 Nogi Reiji). He was followed by six subordinates. He has the "Life of Immortality" ability, which enables him to evolve into a stronger form each time he gets defeated. Each of his forms has natural fighting ability and a unique power of his own. He was eventually destroyed as Cassis Worm Clipeus.
    • Cassis Worm Dimidius (カッシスワーム・ディミディウス Kasshisu Wāmu Dimidiusu, 41, 42): The first form is Cassis Worm Dimidius. His unique power is "Freeze" or the ability to stop the flow of time to the point in which even the power of Hyper Clock Up is purposeless. He was defeated by Hyper Kabuto's Maximum Hyper Cyclone.
    • Cassis Worm Gladius (カッシスワーム・グラディウス Kasshisu Wāmu Guradiusu, 42-44): The second form is Cassis Worm Gladius. His power in this stronger form is advanced into "Absorb" or the ability to absorb other Worms and tachyon energy to gain their powers. He can only absorb tachyon energy sequentially. Simultaneous application of tachyon-based attacks will result to neutralization of the absorbed tachyon. He was weakened by Kabuto, Gattack and Kick Hopper's (Triple) Rider Kick and ultimately defeated right after by Hyper Kabuto's Maximum Hyper Cyclone.
    • Cassis Worm Clipeus (カッシスワーム・クリペウス Kasshisu Wāmu Kuripeusu, 45, 46): The third form is Cassis Worm Clipeus. His power in this form is "Clone" or the ability to split himself into two entities. In addition to the blade arm gained in the previous form, he now gets armored plates and shields across his body. The first copy was destroyed by Gatack's Rider Kick, while the second one was destroyed by Kick Hopper, Punch Hopper's Rider Kick and Rider Punch.
  • Scorpio Worm (スコルピオワーム Sukorupio Wāmu, 19-46): Tsurugi's alter ego, Scorpio Worm is the Worm that killed Tsurugi Kamishiro and his sister and then mimicked Tsurugi. However, Tsurugi was able to overpower it and suppress his Worm heart, but he loses this resolve as he discovers he is a Worm in episode 46. It is also revealed that his stingers can force Worms to return to their human forms, as demonstrated upon the Clipeus's. He was defeated by Hyper Kabuto's Maximum Hyper Typhoon. He later died in his human form after talking to Jiiya.

Native Class[edit]

Natives (ネイティブ Neitibu) are commonly shown in an altered pupa form, but a few Natives have evolved and reached a higher stage in the Worm hierarchy and are classified as "unique".

  • Sisyra Worm (シシーラワーム Shishīra Wāmu, 31-49): Hiyori's alter ego, Sisyra Worm surfaced after Hiyori was in danger of being killed by Worms. Like Tadokoro, she is a Native who chose not to attack humanity. She is considered a special class of Native as she was naturally conceived through birth rather than mimic.
  • Gryllus Worm (グリラスワーム Gurirasu Wāmu, 48, 49): The form Mishima took on after using multiple necklaces to forcefully transform himself into the "strongest Native", able to contend with the likes of Dark Kabuto and Hyper Kabuto and overpower them. He was destroyed by Hyper Kabuto and Gatack's (Double) Rider Kick.
