Jin Nomoto is the Dragon Zodiarts and an antagonist in Kamen Rider Fourze.
After receiving his Zodiarts Switch, Nomoto was sent by Libra to kill the Kamen Riders. He revealed himself to be the Dragon Zodiarts when he told Egawa to stay away from Kengo and then went after Gentaro, Yuki, and Shun. Jin was defeated when Fourze assumed Magnet States and crushed him with the Rider Super Electromagnetic Bomber.
A second Dragon Zodiarts later appeared.It was initially believed that Jin had gotten a new Zodiarts Switch. However, after it was defeated by Fourze all that was left was a lump of black hair. The second Dragon Zodiarts was later revealed to be the work of the Coma Zodiarts.
