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 Dasmader (disguised as a female worker) and Gatezone manipulate children with ESP into causing the country to split from the continent. Kohtaro encountered Schraijin first, and transformed into Kamen Rider Black RX to fight him. When Kohtaro found where the other ESP kids were, he was discovered by Dasmander, Gatenzone, and Schraijin. Schraigin fought Kohtaro before shedding his disguise. Kohtaro then transformed into Robo Rider and fought the Chaps and Schraijin. After the machine that the ESP kids were attached to was destroyed, Dasmander and Gatenzone fled as Robo Rider engaged Schraijin outside. Robo Rider blew off one of his hands with the Vortech Shooter then reverted to Kamen Rider Black RX and used the RX Kick on him. He then called out his Revolcane, disarms Schraijin and cuts off one of his hands before using the Revolcane to destroy him.
