However, when he loses in a duel against Aster Phoenix following his graduation, he starts participating in underground duels and takes on a more aggressive personality, earning him the name "Kaiser" in the Japanese version. However, all the underground duels, in which he battles using shock collars, causes his heart to become weak. He uses a Cyber Dragon deck which he later passes on to Syrus.
