- "When in trouble, Kamen Rider will appear..."
- ―Taki's words to Spike and the other children[src]
Kazuya Taki (滝 和也 Taki Kazuya?) is a fictional FBI agent appearing in Kamen Rider and also in Kamen Rider Spirits, where he becomes a central character assuming the identity of Taki Rider (滝ライダー Taki Raidā?), an homage to the series Skull Man, one of Shotaro Ishinomori's earlier characters, who was adapted for the creation of Kamen Rider 1.
Introduced in episode 13, Taki was assigned to investigate Shocker's activities in Japan. After seeing the original Kamen Rider in action he assisted his temporary successor, Kamen Rider 2, and later both riders in their fight against Shocker and Gel-Shocker, by fighting against the many footsoldiers. After Gel-Shocker's destruction he left Japan and said his goodbyes to everyone from the Tachibana Racing Club, Takeshi Hongo, and Hayato Ichimonji at the Airport.
In Kamen Rider Spirits, Taki is first seen in America explaining Kamen Riders to some of the residents but few people (except children) believe him. One of his young friends, Spike, even called him a Kamen Rider because of his martial arts skills and his use of a motorcycle. Later when Spike is mutated into a Vampire by the evil Father Petrescu, Taki decides to save him going against orders from his superiors, as there were no Kamen Riders present he takes on the Kamen Rider-like persona, Taki Rider. At first he was able to hold his own for a while until Petrescu attacked, removed his mask, and attempted to kill him but was stopped by the untimely arrival of Takeshi Hongo, Kamen Rider 1. Taki then teamed up with Rider 1 and with additional help from Spike, defeated the vampires. Hongo gave Spike an antidote and left. After Hongo left, Taki is seen throughout most of the manga helping the other Riders and other people against the Badan Empire with new equipment that is good enough to fight against the Badan Kaijin.
