...I think it must be an enhanced communication function of the suit. When morphed, sometimes I don't entirely have control of my body. That's how I fought as a Ranger before receiving martial arts training---the Power manipulated my limbs into fighting at a professional level. I had some conscious control over which direction to take and what type of strategy to use, but the mechanics were controlled by an outside force.
