Aatxe
（重定向自Aatxegorri）
Aatxe ([a.atʃe]) is a spirit in the folk mythology of the Basque people. His name is literally translated as "Young Bull", and he is sometimes known as Etsai. He is a cave-dwelling spirit who adopts the form of a young red bull, but being a shapeshifter, sometimes takes the shape of a man. At night, more so in stormy weather, he arises from the hollow which is his lair. He attacks criminals and other malevolent people. He also protects people by making them stay home when danger is near.
