Uni Demon

Uni Demon (ウニデーモン): A sea urchin Neo-Shocker monster from Neo-Shocker's Philippines branch located in Manila.

Biography
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.

Abilities
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.

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