A female recurring character in The Legend of Zelda series. She is a descendant of the mysterious Sheikah tribe that has served the Royal Family of Hyrule for many generations, and is Princess Zelda's personal attendant. She often aids Link in his quest by giving him useful information. Her depiction in each game has varied widely; from a withered old woman, to large, middle aged woman, to a lithe, young bodyguard.
The Impa in Hyrule Warriors: Age Of Calamity is the exact same Impa as the one in Breath Of The Wild, except a hundred years younger. This Impa is much closer to Paya, her future granddaughter, than to any previous versions of Impa, and not just in looks.
