During Lady Eboshi's hunt to kill the Deer God, she shoots it as it transforms, turning it into the humanoid-like Night-Walker, releasing its destructive body.
Later, it euthanizes Okkoto and Moro by taking their life. It heals Ashitaka of his bullet wound, yet interestingly leaves the boar's curse untouched.
The Deer God 'Forest Spirit' is the protector of the Cedar Forest and is the god of life and death. It can transform into a gigantic, translucent humanoid during the night called the Night-Walker. The Forest Spirit looks like deer, but with plant-like antlers and a human-like face.
