King is the human form of the Category King of Spades Undead, the Caucasus Undead, who poses as a teenage boy with an annoying personality.
He loves to cause trouble & mess with everybody. He also steals Dirk's Rouze Cards to push him back into Joker form, giving the deck to Andy in order to enjoy the "mess" to result. He uses telekinesis & can summon his shield by clapping his hands. Though he managed to take his deck from him, Spade Warrior managed to beat him & sealed Caucasus with the Spade Rouzer.
- Despite being referred as the Caucasus Undead, his design is more similar to a rhinoceros beetle than an atlas beetle.
