This article is about a/an kaijin in Kamen Rider (Skyrider).

Uni Demon (ウニデーモン Unidēmon, 39 & 40): A sea urchin Neo-Shocker monster.


His plan is to convert middle age mothers into a female oni army (on a supplementary side they serve as his personal brothel crew). His first attack was a cabaret troupe on a cruise liner. He uses one of the dancers to lure Tsukuba Hiroshi in a trap and captures him. He is destroyed by Kamen Rider 2's Rider Kick.


Apart from his "Oni-Ray" (fired from the red crest on his head) that converts women to oni monsters, his spiky body makes physical attacks useless, and he wields a giant/long spiked club. Any impact causes massive damage and explosions.

Behind the scenes


Uni Demon is voiced by Ritsuo Sawa (沢 りつお Sawa Ritsuo) and portrayed by an unidentified suit actor.
