"Justice never rests!”
Even a mythological spirit of protection can't 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), he's 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!
Unlike all of the previous mythological minifigures in the Collectible Minifigures theme, the Flying Warrior doesn't clearly resemble anyone from classical mythology. Perseus wore a winged helmet, served Athena (the basis of the Battle Goddess minifigure) and could fly (albeit with winged sandals, not wings on his back), but no other aspect of the Flying Warrior's biography or appearance corresponds with Perseus. Most notably, Perseus used a sword and shield, not a spear, he didn't own a suit of armour and he wasn't immortal.
