Settling the Score, Part 1.Mizar takes on both Trey and Quinton at once. Vector uses the diversion of the Emperors to his advantage, putting Alito and Girag under Don Thousand's mind control, as part of his plan to overthrow Nash, even while Alito calls Vector insane for resurrecting Don Thousand. Meanwhile, Caswell and Cathy tell Yuma's family where he has gone. Quinton immediately brings out Dyson Sphere, the massive monster's presence alerting Dumon and Marin to the duel. Mizar, despite being prevented from summoning his Chaos Number immediately, tells Marin and Dumon to go after Yuma and Kite, forcing the brothers to trap the three Emperors in a Sphere Field. Mizar summons Number 107: Galaxy-Eyes Tachyon Dragon and destroys Dyson Sphere. In their respective locations, Kite and Yuma dwell on Trey and Quinton's situation. Girag alerts Nash to Yuma's departure in order to trick him, and Nash promptly returns to Barian World to pursue him. Trey summons Atlandis and attempts to use Dyson Sphere to gain its ATK, but Mizar uses a trap to negate this effect. But the brothers have planned for this, and use Argent Chaos Force, ranking Atlandis up to Chaos Number 6: Chronomaly Chaos Atlandis and attacking Tachyon Dragon. Mizar's trap is destroyed to preserve Tachyon Dragon, allowing Trey to equip Tachyon Dragon to Chaos Atlandis, denying Mizar the conditions necessary to use The Seventh One, enraging him.
