Crowler reveals that Zane Truesdale has the highest grade average of all the soon - to - graduate third - year students , which means that he will get to take part in the final Duel to held at Duel Academy ' s arena this year . He can choose any opponent he wishes . Zane pays a visit to the Slifer Red dorm , and enters the room that his brother shares with Jaden Yuki . He comments that in his three years at the Academy , this is the first time he ' s ever set foot in this dorm . He informs Jaden that he ' s chosen him for his opponent in the graduation match . Zane wants to see how much Jaden has improved since their first Duel . The whole Academy gathers at the arena the next day . The two Duelists shake hands after entering the arena , and Dr . Crowler announces the start of the Duel . Zane allows Jaden to choose who will go first , and Jaden opts to go second so that Zane will be unable to Summon " Cyber Dragon " without Tribute , because Jaden will have no monsters out . Zane activate s " Polymerization " , fusing the three " Cyber Dragons " in his hand to Fusion Summon " Cyber End Dragon " in Attack Position ( and because of such a strong opening move , Jaden realizes that Zane ' s opening hand had prepared him regardless of turn order ) . He then activates " Different Dimension Capsule " , removing a card in his Deck from play in order to add it directly to his hand on his second Standby Phase after activation . He then Set s a card . Based on their previous Duel , Jaden believes the removed card to be " Power Bond " and the Set card to be " De - Fusion " . Jaden Summons " Elemental Hero Wildheart " , and then plays " Wild Half " , which halves " Cyber End Dragon ' s " ATK and Special Summon s a " Half Token " to Zane ' s side of the Field with the same attack points . He then equip s " Wildheart " with " Cyclone Boomerang " , increasing its attack by 500 . He attacks " Cyber End Dragon " , but Zane plays his face - down " De - Fusion " , splitting the weakened " Cyber End Dragon " into three " Cyber Dragons " with 2100 attack each . Jaden replay s his attack , and opts to attack the " Half Token " instead . Both monsters are destroyed , and " Cyclone Boomerang ' s " effect activates , destroying " Different Dimension Capsule " and dealing Zane 500 damage . Zane draws , and the effect of the " Card from a Different Dimension " that he removed from play with " Different Dimension Capsule " is activated - it returns to his hand and both players draw two cards . Jaden is astonished that the selected card was not " Power Bond " , and Chazz Princeton realizes why Zane didn ' t choose " Power Bond " . He had used four cards just to Summon " Cyber End Dragon " , and had he opted to use " Power Bond " and " De - Fusion " , he ' d have been left with no cards in his hand . Zane attacks with his first " Cyber Dragon " , and Jaden activates his face - down " Draining Shield " , negating the attack and adding the attack points to his Life Points . Zane attacks with his other two " Cyber Dragons " , leaving Jaden with 1900 Life Points . Zane Sets a card to end his turn . Syrus states he ' s worried - and he wouldn ' t be if Jaden was Dueling as he usually does . However , Jaden doesn ' t seem to be having any fun with this Duel and is overthinking things . Jaden activates " The Warrior Returning Alive " to return " Wildheart " to his hand , and then plays " Polymerization " , fusing it with " Elemental HERO Bladedge " to Fusion Summon " Elemental HERO Wildedge " . He then attacks all three " Cyber Dragons " with " Wildedge ' s " effect , believing he ' s neutralized the main threat of Zane ' s Deck . Zane activates his face - down " Return Soul " , returning his three " Cyber Dragons " to his Deck . Zane claims he ' s now regretting selecting Jaden as his opponent , as Jaden isn ' t playing with his heart as he usually does , but with his head . He activates " Future Fusion " , allowing him to fuse the three " Cyber Dragons " now in his Deck to Fusion Summon " Cyber End Dragon " once more , however , it cannot attack this turn . Jaden Sets three cards . Zane draws and activates " De - Fusion " , then plays " Power Bond " to Fusion Summon " Cyber End Dragon " again , but with doubled attack points .
