If my Kingdom Hearts OCs were ponifed, i would like them to be unicorns (since they can do magic like their brothers). Kiana's cutie mark would be a Kingdom Key, Xikana's cutie mark would be Oathkeeper and Oblivion, Aura's cutie mark would be a Wayward Wind, and Vanity's cutie mark would be a Void Gear. Kiana's magic aura would be black, Xikana's aura would be purple, and Aura's aura (hehe) would be a mixture of black and purple, and Vanity's aura would be red. Kiana's mane would be dark brown, Xikana's mane would be light brown, Aura's mane would be light brown as well, and Vanity's mane would be black. Their coats would be tan, Kiana's, Xikana's, and Aura's eyes would be dark brown, and Vanity's eyes would yellow.
