The four "Valkyries" in world myths and legends usually refer to:
- Athena: The goddess of war and wisdom in ancient Greek mythology, she was the daughter of Zeus and one of the twelve main gods of Olympus. She has been resident in the mortal world since the birth of mankind, teaching them all kinds of survival knowledge and creating the first survival tools for mankind.
- Valkyrie: The goddess of war in Norse mythology, originally meaning "gluttonous corpse eater", later evolved into "the woman who picks the war dead". Valkyries are the daughters of the kings of the earth chosen by the gods, or the daughters of Odin herself, or the virgin warriors who swore to serve the gods and were chosen by the gods to ascend to heaven. They bestow beautiful kisses on the battlefield on the dead and lead them to Valhalla.
- Sehmet: The goddess of war in ancient Egyptian mythology, worshipped by the pharaohs as a protector. She leads the war and is also in charge of medical care, in the form of a lioness or lion-headed woman.
- Nine Heavenly Xuannu: The goddess of war in Chinese mythology, the goddess of justice in charge of the art of war and the number of arts. Although in modern times, the Nine Heavens Xuannu may not be as well-known as Athena in China, its origins are very ancient, dating back to pre-Qin time.
