This article is about a/an kaijin in Kamen Rider, the original series.

Kinokomorgu (キノコモルグ Kinokomorugu, 24, 25, Rider vs Shocker & Rider vs Ambassador Hell) – A mushroom monster. He is able to spit a white dust that causes permanent sleep and is equipped with a knife. His emblem, worn by the soldiers of the base that modified him, is a two-headed mushroom. A condemned criminal was taken from prison by Shocker soldiers. After hearing the organization's goals, he thought they were interesting and decided to join them. Fused with a special mushroom, he became Kinokomorgu. Kinokomorgu went on a parade alongside several Shocker soldiers, quickly capturing children curious enough to follow them. He defeated and captured Rider #2 with his special ability, but the Kamen Rider was saved by Taki. They fought again later, but he was destroyed by Kamen Rider #2's Rider Kick. The explosion created by his death destroyed his own Shocker base. Kinokomogu returned in the movie Kamen Rider vs. Shocker, fighting against Kamen Rider #2 again to capture a researcher's daughter, but he was destroyed easily by Kamen Rider #2's Rider Kick. Rebuilt once again by Shocker, his last appearance was in the movie Kamen Rider vs. Ambassador Hell. He helped in delaying Kamen Rider #1 from reaching a Shocker base and was left behind, alive, by Kamen Rider #1 afterwards.
