His animal form is the Black Dragon and his stellar animal is the tortoise-snake. By virtue of his association with the north, he has been identified and revered frequently as a representation of the supreme God of Heaven.
His planet is Mercury. His animal form is the Black Dragon and his stellar animal is the tortoise-snake.

## Taoist myths involving the Black Deity

A Taoist title of Heidi is the "Dark (or Mysterious) Heavenly Highest Deity" (玄天上帝; Xuántiān Shàngdì). According to a myth, during the fall of the Shang, the Demon King ravaged the world, so that Yuanshi Tianzun ordered the Jade Emperor to appoint Heidi as the commander of twelve heavenly legions to fight this evil. Heidi defeated the Demon King and was subsequently granted the title of Mysterious Heavenly Highest Deity. In temples dedicated to him, the bronze tortoise and serpent under the feet of his image signify that the good always prevails over evil.
