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

Torikabuto (トリカブト Torikabuto, 37 & Rider vs Shocker) – An aconitum monster. His personal mark worn by his soldiers was an aconitum silhouette. He was able to spit a strong green acid that melts an adult human in seconds and extend his white hand into a large tentacle. Spread throughout Japan various artificial flowers able to release poisonous gas. However, he was seen by a child, and eventually that led Kamen Rider #2 to finding him. Meanwhile, revived monsters were about to test the poisonous gas on children, but were stopped by Taki, who used it against them. Torikabuto was destroyed by Kamen Rider #2's Rider Punch. Torikabuto returned in Kamen Rider vs. Shocker, as a member of the large kaijin army. He faced Kamen Rider #1 and 2 together, trying to capture a girl called Tamami, only to be destroyed by being thrown onto one of his partners for that mission, Sarracenian.
