The many red spheres along a Yanmega's body, frequently mistaken for segments of the exoskeleton, are in fact fully functional eyes. Although smaller in size than the two larger eyes at the pokemon's front, they are sufficiently numerous to give these creatures 360-degree vision. The greater size of a Yanmega's front eyes is actually a means to compensate for their smaller number, and Yanmega are often found using their tails to aid their relatively weak front eyes in order to get a better view of things in front of them.
A Yanmega's signal beam, like those of most pokemon who learn this technique, is fired from the eye, but a Yanmega's sixteen eyes allow them to shoot multi-colored lights from virtually any angle. This ability is particularly useful in aerial combat, where pokemon maneuver for advantage in three dimensions and a direct hit is often necessary to cancel out the weakness of this attack against flying pokemon. Yet even against grounded targets, Yanmega can use their eyes to gain much greater precision than most pokemon, and, rather than seek to hit a distant target, can aim for the eyes from afar to leave their foes unable to fight back.
A few powerful Yanmega learn to shoot light not in one direction, but in all sixteen at once, a fact which mythologies around the world have connected with the Sun's rays of light. At times, the Sun itself was represented as a giant Yanmega; at others, they were perceived as messengers of the Sun God or Goddess. Despite the beauty which drove many onlookers to this pokemon, this association was always reinforced by the danger these signal beams and the brightness of the Yanmega emanating them pose to the retina; after all, one should never look directly at the Sun.
