|This article is about a/an kaijin in Kamen Rider Black RX.|
A blue robot sent to attack Kohtaro while he was looking for Hitomi. He is able to teleport, emit repulsion force from his hands, and could fire energy blasts from his eyes. Controlling Joe as a puppet, Nexticker forces him to fight Kohtaro when he almost saved Hitomi. After surviving the attack, Kohtaro is ambushed by Joe while on his to the Valley of Miracles, fighting him as RX before disabling the robot's mind control abilities by using one of Joe's Sai. Assuming the form of RoboRider, RX converts Acrobatter to Roboizer and overwhelms Nexticker before blasting him with the Vortech Shooter.
