Unlike Juudai, whose unorthodox plays depend on chance, The Supreme King is straightforward and his arsenal uses a variety of effects that range from card destruction to immunity from opposing card effects that effectively reflect the supremacy and omnipotence of a monarch. It is able to bring out any kind of high-Level Fusion Monster with dreadful effects in an instant. The Supreme King also has access to the 'Super Polymerization' card, which can use Fusion Material from both sides of the field and can't be negated by Spell and Trap Cards or the effects of Monster Cards. While in possession of Juudai's body, he plays an 'Evil Hero' Deck, vile incarnations of Juudai's 'Elemental Heroes.' Like Jaden, The Supreme King's tactics revolve around Fusion Summoning except he uses his own signature card, 'Dark Fusion,' a warped version of Juudai's traditional 'Polymerization.' 'Dark Fusion' prevents the monster being destroyed by Spell and Trap Cards during the turn it was summoned. His demonically golden eyes (and overall visage) show no emotion other than anger and hatred. He is also very taciturn he only talks when necessary or to spite his enemies, and when he talks, he speaks in a slightly condescending tone. The Supreme King is cold, collected and ruthless, and is willing to sacrifice as many people as he has to in order to complete Super Fusion.
