K'NEX Jammer












Zack Armstrong was chosen for the XTractors Team because of his techno-savvy. While passing through ZeKor's atmosphere, Zack Armstrong realizes that he has merged with the ship's hovercraft - and attached to his body is a glowing PowerCore. Zack Armstrong becomes "Jammer." Jammer's PowerCore enables him to confuse his enemies by "jamming" their brain waves. His mastery of computers and technology makes Jammer an essential part of the XTractors.
