Shining Armor is a unicorn and Twilight Sparkle's older brother. He is the Captain of the Canterlot Royal Guard, serving under Princess Celestia, and bears the title of Prince. He first appears in A Canterlot Wedding, the two-part finale of the second season of My Little Pony Friendship is Magic, alongside Princess Cadence. A blurb on one of the toy sets featuring Shining Armor says that he and Princess Cadance "lead the Crystal Empire together!"
