Cheetahkatatsumuri

Cheetahkatatsumuri appeared in 2015 movie called Super Hero Taisen GP: Kamen Rider 3. Cheetahkatatsumuri (チーターカタツムリ Chītā Katatsumuri, lit. "Cheetah Snail") is a cheetah/snail monster of Shocker. He is as well the alternate reality version of Lt. Genpachiro Otta of Special Investigation Unit.

In an alternate world created by the History Modifying Machine where Kamen Rider 3 killed the Double Riders 1 and 2, Shocker managed to achieve complete world domination. Genpachiro Otta is a lieutenant of Shocker and had been remodeled as one of their cyborg monster, Cheetahkatatsumuri.

During the Kamen Riders' final battle against Shocker, Cheetahkatatsumuri immobilizes Deadheat Mach with his slime, allowing an opening for several Shocker monsters to bombard Mach with their combined power, resulting in Go's death. However, Cheetahkatatsumuri is soon after confronted by the three Riders, #3, #2, and #1. Beaten back by the former Shocker cyborgs, Cheetahkatatsumuri is destroyed by their combined Rider Triple Kick.

When the timeline was seemingly fixed, Shocker still remains in existence, and Cheetahkatatsumuri (no longer being an identity of Genpachiro) as well responsible in one of Go's death during Shinnosuke's Déjà vu. After the truth about the time loops is exposed he battles with and is defeated by Kamen Rider Deadheat Mach.
