The group reach a door standing alone in the meadow. After opening it, they wind up in a hanger, similar to the place where the blimp landed. They are confronted by [[Nezbitt]], who has taken the form of "[[Robotic Knight (anime)|Robotic Knight]]". Nezbitt plans to Duel them one by one, starting with Serenity, but after much debate ends up facing the three of them at once.<ref name="ep 106" />

Duke and Tristan spend the first two turns, trying to correct Serenity's mistakes. Tristan Summons weak monsters in [[Attack Position|Attack Mode]] to draw Nezbitt's attacks to him rather than Serenity. After pumping his new Deck Master, "[[Perfect Machine King (anime)|Perfect Machine King]]" to high [[ATK]], Nezbitt attacks one of Serenity's monsters, but Tristan uses his Deck Master, "[[Super Roboyarou (anime)|Super Roboyarou]]", to take the attack and prevent her from losing. He also uses its Deck Master effect to [[Set]] 1 card, raising its ATK to 2200. "Perfect Machine King" destroys "Super Roboyarou", defeating Tristan.<ref name="ep 106" />
