These two My Little Pony papercraft are the Shining Armor and the Princess Cadance, created by RocketmanTan. Shining Armor is a unicorn pony and Twilight Sparkle's older brother. He is Captain of the Canterlot Royal Guard. His cutie mark is a blue shield with a pink-purple six pointed star in the middle, and it also has three light blue stars above the shield. He first appears in A Canterlot Wedding, the two-part finale of the second season of My Little Pony Friendship is Magic, alongside his wife Princess Cadance.
Princess Cadance is a Pegasus unicorn pony who is first featured in A Canterlot Wedding - Part 1, alongside Shining Armor, her husband-to-be. She is the former foal-sitter of Twilight Sparkle as shown in a flashback, and becomes Twilight's sister-in-law after the marriage of herself and Shining Armor in A Canterlot Wedding - Part 2. A New York Times ad states she is the niece of Princess Celestia.
