Ambassador Hell

 Ambassador Hell is an executive member from Shocker's branch in the West Coast of USA. Hell takes command of Japan's branch after Doctor Shinigami's destruction. Hell captures the rider's friends and calls out Kamen Rider 1 and becomes his Inhumanoid form, Garagaranda, a rattlesnake kaijin able to use his whip arm as a weapon, similar to the whip he uses without his Inhumanoid form. He also has the ability to burrow underground. While Ichimonji frees their friends Rider 1 engages Hell in combat. He then manages his Rider Kick on Garagaranda reverting him back to his human form. He curses the Riders and screams to Shocker's perseverence before he explodes and the Great Leader scatters Shocker.

In Birth of the 10th! Kamen Riders All Together!! it is revealed that Hell has a cousin named Ambassador Darkness who is the leader of the Badan Empire and is destroyed by Kamen Rider ZX's ZX kick.
