Justice never rests!
Even a mythological spirit of protection canít be everywhere all the time. When the Battle Goddess decided that her mission of justice could use a helping hand, she selected a warrior of the ancient world who had proven both his valor in combat and his great love of peace. Granting him the gift of immortality, she gave him golden, winged armor and armed him with a mighty spear of thunder.
Throughout the ages, the Flying Warrior has tirelessly carried out his duty of defending the weak and innocent. To pay the bills (even an ancient hero needs an apartment and the occasional pizza), heís recently become a museum guide. Tour groups are really impressed by his booming voice and first-hand knowledge of centuries of history, and kids on class trips love it when he accidentally knocks things over with his wings!
