- The bio-pulse line is a means of monitoring a Warriors bodily functions while flying Vipers, in order to determine the current condition of a pilot. The information from this is said to be "fed to an on-board computer that compares [the current data] with stored records of the Warriors natural responses". From this information, the computer can "make instantaneous corrections by adjusting the pressure in the Warriors g-suit, changing the mix of the breathing solution, or by injecting needed hormones and enzymes directly into the bloodstream".
