The Jack of Diamonds is the cowardly, snobbish, fat-posteriored, rude son of the Diamond family. He was originally intended to be the next rightful heir to the Wonderland throne beside Alyss in an arranged marriage. Once the Imagination War came into full swing, however, he chose to act as a double agent in the conflict, playing whichever way best suited his interests while only revealing enough to keep him trusted on either side. This betrayal was uncovered by Dodge Anders, and he is later locked away as a miner in the crystal mines by Alyss.
