He loves to cause trouble and mess with everybody. He also steals Hajime's Rouze Cards to push him back into Joker form, giving the deck to Mutsuki in order to enjoy the "mess" to result. He uses telekinesis and can summon his shield by clapping his hands. Though he managed to take his deck from him, Blade managed to beat him and sealed Caucasus with the Blay Rouzer.
