Nago

"Disgusting little creatures. Soon, all of you will feel my hate, and suffer as I have suffered!"

Nago was a boar god who turned into a demon after being shot by Eboshi and later killed by Ashitaka with his arrows. When Nago's curse touches Prince Ashitaka, it curses him as well, and dooms him to be killed by the mark.
