|This article is about a/an monster in Kamen Rider, the original series.|
Wolfsbane (トリカブト Torikabuto, 37 & Rider vs Shocker) – An aconitum monster. His personal mark worn by his Combatants was an aconitum silhouette. He was able to spit toxic fluid that melts an adult human in seconds and extends his white hand into a large tentacle. Killer flowers were spread throughout Japan as part of Operation: G. However, he was seen by a child named Mitsuru Kimoto, and eventually, that led Kamen Rider 2 to find him. Meanwhile, revived monsters were about to test the poisonous gas on children, but were stopped by Taki, who used it against them. Wolfsbane was destroyed by Kamen Rider 2's Rider Punch. Wolfsbane returned in Kamen Rider vs. Shocker, as a member of the large monster army. He faced Kamen Riders 1 and 2 together, trying to capture a girl named Tamami, only to be destroyed by being thrown onto one of his partners for that mission, Sarracenian.
