Royal Pin, or Pinprick, is a male unicorn with a blue coat and a light blue and white mane and tail. His eye color varies between gold, amber, and blue. His cutie mark varies between a safety pin, an hourglass, three chess pieces, and a horseshoe, and his horn size varies. He is unnamed in the show, but he is named "Royal Pin" sometimes with a trademark symbol and "Pinprick" in different merchandise and other media.
