This article is about a/an rider in Kamen Rider Kabuto.

Issei Kurosaki (黒崎 一誠 Kurosaki Issei) was Kamen Rider Caucasus (仮面ライダーコーカサス Kamen Raidā Kōkasasu, Masked Rider Caucasus), a Kamen Rider that only appears in Kamen Rider Kabuto: God Speed Love (when he tries to destroy all humanity). He transforms using the power of the gold Kabutech Zecter, the Caucasus Zecter. His power exceeds the power of most Kabuto Riders.


Kamen Rider Kabuto: God Speed Love

Caucasus kills Hercus

Caucasus instantly kills Kamen Rider Hercus

He first appeared when he kills Kamen Rider Hercus via Hyper Clock Up and drops his blue rose at the corpse. One day later, he was sent by ZECT to go aboard on a space station to ensure their secret mission goes as planned.

However Kabuto and Gatack were able to get onto the space station to discover the real plot. Though at first both riders are outmatched by Caucasus due to the Hyper Zecter, Gatack successfully held him off allowing for Kabuto to steal the Hyper Zecter and eject him into space. Kabuto sends Gatack back to the Earth via an escape pod as he was completely exhausted.

But this doesn't stop Caucasus from having his revenge and killing Gatack by smashing the escape pod's window, sucking the contents of the pod into the vacuum of space. But Kabuto had predicted this and uses the Hyper Zecter to go back in time to prevent Gatack's death, and kills Caucasus by kicking him to the missile before it hits the meteor.
