Gynagiskhan

Gynagiskhan appeared in 1988 TV series called Kamen Rider Black RX. He's known as the "Knight of Wind", Gynagiskhan was an insectoid-like horseman with sensitive hearing who used a glaive in battle and could manipulate winds up to 100 mph. He brought Kohtaro and his friends into the Desert of Fierce Winds where Professor Walter and his followers were exiled. After killing Walter, Gynagiskhan battles RX with Reiko's musical necklace disrupting Gynagiskhan long enough for RX to until he was weakened enough to kill him with the Revolcane.

He returned in the Kamen Rider: Run All Over the World movie to assist Deathgaron, United Triplon and Musalabisala into attacking the Kamen Riders only to be destroyed by a team Rider Kick.
