Schraijin

An Asura-like robot. He wields a spear, two swords, a sickle and a pitchfork in battle. He can also spew acidic foam from his hands. Disguised as a headmaster, he helped General Dasmander (disguised as a female worker) and Gatenzone manipulate children with ESP into causing the country to split from the continent. Kotaro encountered Schraigin first, and henshined into Kamen Rider Black RX to fight him. When Kotaro found where the other ESP children were, he was discovered by Dasmander, Gatenzawn, and Schraigin. Schraigin fought Kotaro before shedding his disguise. Kotaro then transformed into Robo Rider and fought the Chaps and Schraigin. After the machine that the ESP children were attached to was destroyed, Dasmander and Gatenzawn fled as Robo Rider engaged Schraigin outside. Robo Rider reverted to Kamen Rider Black RX and used the RX Kick on him. He then called out his Revolcane and disarmed Schraigin before using the Revolcane to destroy him. Episode 34
