Valkyries have the power to create doubt, confusion, and intimidation in their opponents. When using the power of confusion the Valkyrie's true form is seen, which resembles a gaunt skull.
They can also restore consciousness to a comatose person, and can cause someone to die by willing it.
Valkyries live several life cycles until their final one, and when they are near the end of one cycle they begin to lose volumes of hair each time they use their powers. When a life cycle has expired and they die, they are reborn with an accelerated aging process between birth and adulthood.
At the start of a reincarnated life, Valkyrie powers and abilities are extremely enhanced. In their final life cycle and similar to puberty, Valkyries "gain their wings" in a process that is painful. Their powers increase as they get older again.
- In Norse mythology, a Valkyrie (from Old Norse valkyrja "chooser of the slain") is one of a host of minor female deities who decides who falls and dies in battle. Selecting among half of those who die (the other half go to Fólkvangr, the afterlife field of the goddess Freyja), the valkyries bring their chosen to the afterlife hall of the slain, Valhalla, ruled over by the god Odin. There, the deceased warriors become einherjar. When the einherjar are not preparing for the events of Ragnarök, the valkyries bear them mead. Valkyries also appear as lovers of heroes and other mortals, where they are sometimes described as the daughters of royalty, sometimes accompanied by ravens, and sometimes connected to swans or horses.
