Nexticker

A blue robot sent to attack Kotaro while he was looking for Hitomi. Controlling Joe as a puppet, Nexticker forces him to fight Kotaro when he almost saved Hitomi. After surviving the attack, Kotaro is ambushed by Joe while on his to the Valley, fighting him as RX before disabling the robot's mind control abilities. Assuming the form of RoboRider, RX converts Acrobatter to Roboizer and overwhelms Nexticker before blasting him with the Voltic Shooter.
