Leo Zodiarts

The Leo Zodiarts appeared in 2011 TV series called Kamen Rider Fourze. The Leo Zodiarts (レオ・ゾディアーツ Reo Zodiātsu) is the Horoscopes Zodiarts form associated with the constellation of Leo. He has superhuman strength, sharp claws, and can emit sonic balls from his mouth. His Nova ability allows him to move at superhuman speeds.

A Leo 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 Leo is the eighth and last of the Horoscopes to be destroyed before Wizard appears to deal with the remaining four, by Fourze Cosmic States' Rider Super Galaxy Finish Limit Break.

A dummy Leo 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 Cancer Zodiarts, Leo was destroyed by Fourze's Giantfoot Module which launched them both into Enigma's invisibility screen, exposing the device.

In an event witnessed by Sento Kiryu, a Leo Zodiarts was among numerous monsters whom engaged the first 18 Heisei Riders before being wiped out by the Vortex Time Break of Kamen Rider Zi-O BuildArmor.
