The Zodiarts are monsters themed after the 88 Western constellations and the antagonists of Kamen Rider Fourze.
A Zodiarts is created when an ordinary human uses a Zodiarts Switch to transform into a being of Cosmic Energy, bestowing upon them incredible powers. While the human (known as a "Switcher") can at first shift freely between his or her normal and Zodiarts forms, after a certain number of uses the Zodiarts Switch will mutate into a form known as "Last One". If the Switcher uses the Zodiarts Switch in its Last One state, they will be irreversibly turned into a Zodiarts.
After being switched off, a Zodiarts Switch vanishes, preventing it from ever being used by its Switcher to become a Zodiarts again. However, a user whose switch vanished can use a different switch to become another Zodiarts.
