The Supreme King has revealed himself to be Jaden Yuki . Jim Crocodile Cook questions him on why , but he refuses to respond , and the King ' s strongest minions begins attacking him . Axel Brodie rolls away and Summons " Fire Trooper " , which distracts them long enough to allow him and Jim to escape . When the Duelists of Death suggest they chase them down , the Supreme King orders them to let them go , stating he has no interest in warriors who wish to run instead of fight before returning back to his castle . As they hide , another flashback of Jim ' s past is shown . After saving Shirley from a , Jim awakens with his right eye now bandaged up , as it is in the present . An old man has saved him and Shirley and he reveals the under the bandages he has placed the Eye of Orichalcum . He says that at some point , this eye will create a miracle and allow him to save a friend . In the present , Jim believes that the time has finally come , and again moves towards The Supreme King ' s castle . Jim yells for The Supreme King to come out , but The Duelists of Death exit first . Jim says he has no business with them , and wants their King . The Supreme King exits the castle and tells The Duelists of Death that he ' ll show them no mercy if they interfere with the Duel . The five stand down , rushing to the side to watch . The Duel begins and Jim deals 500 damage on his first turn by Summoning " Shell Knight " . Axel comments that it was a good first turn , while The Duelists of Death counter by saying that it was a horrible turn , and The King usually defeats his opponent in one turn . Despite this statement , Jim survives the turn with 1900 Life Points after taking damage from the attack and effect of " Evil Hero Inferno Wing " . This attack destroys the bandages covering Jim ' s face , and The Eye of Orichalcum reveals itself . Jim states it will allow him to save Jaden from himself . The eye glows , and the screen pans to show what ' s going on in Jaden ' s head and the eye allows Jim and Axel to " enter " it . They find Jaden sitting on the ground , wearing his Slifer Red uniform rather than the armor of The King , though his eyes still glow the yellow of The King ' s . He repeatedly questions what he did wrong and why things have turned out this way . Jim attempts to speak with him , but he is completely unresponsive . Jaden thinks back to his Duels with Mr . Stein and Thelonious Viper , when both told him that he has nothing to fight for , as he only Duels for fun , and therefore cannot win and lacks the " darkness of heart " ( The flashback with Mr . Stein is cut from the English version ) . Despite this , he won both Duels . But Jaden now questions whether they were correct - that he won ' t ultimately win this conflict , because he lacks a true reason to fight . With his mind at its weakest , The Supreme King ' s dormant personality within him begins to speak to him , again telling him that he must become evil to defeat evil , and urging him to complete Brron ' s " Super Polymerization " card by gathering the souls of Duelist s . They return to the Duel , and Jim reduces the King ' s Life Points to 1850 , and hopes the attack will release Jaden from the darkness . Jaden ' s eyes briefly show through , before turning yellow once more . Featured Duel : Jim Crocodile Cook vs . The Supreme King .
