They joined the Maverick Hunters after a recent Maverick attack in Central Point, but shortly after joining, they revealed they are Hyper Limit Reploids disguised to infiltrated the base, seeking to gain the trust of the Maverick Hunters and destroy them from within., attacking with several Mechaniloids like Maoh the Giant and Victoroids. Zero takes care of the Mechaniloids while X fights against them, but the four became too strong to him as even their weakness, like Electric Spark and Rushing Burner, didn't work.
