The Jade Mountain Prophecy
Harrier was posted by Queen Ruby to watch over Chameleon when he used Darkstalker's scroll to turn Tourmaline back into her Ruby form. Chameleon changed into his NightWing form, Shapeshifter, and knocked Harrier out in a single blow with his tail. Frightened, a female guard fled to Queen Ruby and alerted her about Chameleon's attack, afraid Ruby would hurt her. Instead, Ruby told the guard to go check if Harrier was okay, and that they would not be punished for not notifying their mistake.
