Kupua
In Hawaiian tradition, kupua are shapeshifting demigods and magical beings who can take many forms, with well-known examples such as Kamapua'a (the hog-god) and figures in the epic cycles collected in the 19th century. The description is condensed to the attested shapeshifter-demi god tradition; the invented 'summoned by kahuna' and 'twilight veil' specifics are removed.
