Cancer Zodiarts

The Cancer Zodiarts appeared in 2012 TV series called Kamen Rider Fourze. The Cancer Zodiarts (キャンサー・ゾディアーツ Kyansā Zodiātsu) is the Horoscopes Zodiarts form associated with the constellation of Cancer. He has a large pincer claw for the left arm, a thick shell, and can release explosive bubbles from his mouth. His Nova ability allows him to become a giant crab armed with larger pincer claws.

A Cancer Zodiarts was part of a force of twelve dummy Horoscopes which were manifested from a replica set of the twelve Horoscope Switches. Gamou had intended to give these to Foundation X in exchange for ¥100,000,000. However, the transaction meeting was interrupted by Inga Blink who stole the Switches for space warfare. The dummy Horoscopes would make their appearance to stop the Kamen Rider Club from getting to the Exodus shuttle, being engaged by Kamen Riders Fourze and Meteor. The dummy Cancer is the first of the Horoscopes to be destroyed, by Fourze's Limit Break utilizing the power of the Chain Array, Hammer, and Chainsaw Modules.

Cancer Nova was one of Amadum's monsters in the world within the Magic Stone.

A revived Cancer Yummy was one of the various past monsters part of the army of Bujin Gaim in the Sengoku Period world of the Bujin Riders. It is destroyed along with the Kamakiri Yummy, Pisces Zodiarts, and Phantom Khepri by Armored Rider Ryugen Double Arms' Rider Shooting.

A dummy Cancer Zodiarts was one of a quartet of Horoscopes Zodiarts which were summoned by Kaisei Mogami, using the replica Switches created by Foundation X, to defend the "World of Ex-Aid's" Enigma device. They were, however, engaged by Amanogawa High School teacher Gentaro Kisaragi, who had returned as Kamen Rider Fourze. Alongside the Leo Zodiarts, Cancer was destroyed by Fourze's Giantfoot Module which launched them both into Enigma's invisibility screen, exposing the device.
