Nike (or Nicé) was the winged goddess or spirit (daimon) of victory, both in battle and peaceful competition. When Zeus was gathering allies at the start of the Titan War, Styx brought her four children, Nike (Victory), Zelos (Rivalry), Kratos (Strength) and Bia (Force) into the service of the god. Nike was appointed his charioteer, and all four were appointed as sentinels standing beside the throne of the god. Beyond this Nike never acquired any distinctive mythology of her own.
Nike was depicted in ancient Greek vase painting with a variety of attributes including a wreath or sash to crown a victor, an oinochoe and phiale (bowl and cup) for libations, a thymiaterion (incense burner), an altar, and a lyre for the celebration of victory in song. In scenes of the Gigantomachia (War of the Giants) she often appears driving the chariot of Zeus. In mosaic art and coins Nike isoften shown holding a palm branch as a symbol of victory.
Nike was closely identified with the goddess Athena, sometimes appearing merely as an attribute of the goddess. Sometimes the goddess was pluralised into Nikai.
Nike can change her appearance and turn into her Roman counterpart, Victoria. As Victoria, she becomes more disciplined, warlike, and militaristic. If the minor gods are honored there, it is distinctly possible that she has more children at Camp Jupiter. Although Nike was greatly praised in Ancient Greece, it was Victoria who was truly worshiped in Rome.
Nike has not yet appeared in the series, however her domain suggests she has some level of influence over victory and competition.
