A pneumatic action figure doll is disclosed with articulated limbs controlled by a hand operated pneumatic pump. The articulated limbs may comprise connected limb members and links configured to move in a plane. Operation of the handheld pump may cause the articulated limbs to extend and retract. When the limbs are arms, operation simulates arm swinging motions similar to fighting or boxing. The doll may include actuators to extend articulated arms in response to operation of the pump. The doll may be articulated at the waist to provide movement of the torso when articulated arms extend and retract. The doll may be used alone or with other similarly configured dolls. The dolls may be placed opposite each other. Simultaneous extension and retraction of the doll arms in response to simultaneous operation of the handheld pumps may resemble fighting or boxing between the dolls.
