During the Standby Phase , " Poisonous Viper " inflicts 500 damage to Jaden . He Summons " Winged Kuriboh " in Attack Position , and both Reggie and David instantly realize that it ' s a spirit card . The shadow watches from the earrings of David and Reggie , and can sense that " Winged Kuriboh " is the last piece it needs to return to its complete self , as a human figure is shown .

He activates " Alchemical Experiment " , Tributing " Winged Kuriboh " to Special Summon " Winged Kuriboh LV9 " by removing " Elemental Hero Stratos " , " Terra Firma " and " Rai - Oh " in his Graveyard from play . " Winged Kurioh LV9 ' s " attack and defense is equal to the sum of the removed monsters . Jaden attacks with the 6200 - attack " Winged Kuriboh " , winning the duel . Jaden declares that he had fun , but Seika is frustrated to have pushed Jaden so far into a corner and still lose . A short time later , David and Reggie confront Jaden in the hallway to ask about his spirit card , and a shadowed human figure is shown standing in front of stone tablet , with only one small piece missing .
