Changes

Thousand also revealed that due to the recoil of his engagement against the Original Number, Astral's power was split and became fifty of the "Numbers". Those cards scattered across the [[Earth (planet)|Earth]], designating the location of the [[Numeron Code]]. After that, seven of those "Numbers" suppressed Thousand's power and chose their owners, attaching themselves to various heroes and sages of Earth (shots of [[Alito]], [[Vector]], and [[Girag]] with their respective [[Mythyrian Number|"Mythyrian Numbers"]] are shown over this).

However the arrival of Kite's spirit allowed them to summon "[[Number 100: Numeron Dragon]]", which they used to defeat "Numerronius". Finally, Thousand Summoned "[[Number Ci1000: Numerronius Numerronia]]" which almost guaranteed his victory, but a combination of [[Number 39: Utopia]] powered by the effects of "[[Number 73: Abyss Splash]]" and "Numeron Dragon", allowed the monster to acquire 204,000 ATK points to vanquish Thousand.

=====Barian's Top Guardian vs. ZEXAL Wielders=====

Before dying, Don Thousand asserted that his true curse had not been dispelled while transferring his remaining power and "Numbers" to Nash who challenged Yuma to a final rematch for the Numeron Code .<ref name="ep141">{{episode|Yu-Gi-Oh! ZEXAL|141|ref}}</ref>

When they were resuscitated , they find themselves in a small room surrounded by pillars, while [[Baria Crystal|Baria]] and [[Astrite]] crystals floated around. Before them is a winding staircase, which leads straight into the Astral World, the [[Astral Tower]] visible. Yuma says it cannot be. Turning, Yuma observes another staircase leading to Earth - which is still fused with the Barian World. Yuma questions what is going on - they should have protected the world by defeating Thousand. Nash appears behind them in human form, saying that Earth and the Barian World are still merged - and they are currently in a small location between that merged world and the Astral World. Yuma mutters "Shark..." Nash explains that right now, the two worlds are pulling against one another. If it keeps up, the two worlds will collide, resulting in the Astral World's destruction.

Yuma activated "[[Rank-Up-Magic Astral Force]]" to create "[[Number 39: Utopia Beyond]]". "Barian Hope" would have been destroyed, but Nash countered with "[[Overlay Menace]]" to protect the other Emperors and "[[Xyz Trip]]" to negate the attack. Nash attempted a counterattack, but Yuma's activation of "[[Weaker Overlay]]" and "[[Damage Reactor]]" allowed "Utopia Beyond" to destroy "Barian Hope".

Yuma questions if he really believes they can no longer understand each other. Nash says Yuma doesn't get it - they already understand each other. Nash explains that he's known how Yuma feels for a long time and how he felt when they fought. Yuma mutters "Shark...", but Nash continues that even friends that understand each other may stop being friends. Nash adds that there are people who believe in him and that are still fighting by his side. The spirits of the other [[Seven Barian Emperors|Barian Emperors]], [[Iris]] and the soldiers of the [[United Lands of the Poseidon Ocean]] appear around him as he vows that he cannot betray them by losing. Yuma mutters "lose..." and thinks back to [[the Door]] telling him that he could obtain a new power - but the price would be losing that which is most important to him. Astral turns to Yuma and Yuma thinks about what it is he would lose. Nash tells Yuma to come at him and Yuma wonders if what he'll lose will be Shark or Astral. He determines it must be neither - as he would never allow himself to lose either of his best friends.

Nash weakened "Utopia" with "[[Friller Rabca]]" and brought out "[[Submersible Carrier Aero Shark]]" as well, but Yuma survived with "[[Damage Take-Over]]". Using ZEXAL, Yuma and Astral created "[[ZW - Sylphid Wing]]", but Nash revived "Barian Hope" using "[[Rebirth of the Seven Emperors]]" at the expense of his Rank 3 monsters. Yuma pushed the attack, but Nash used "[[Draw of Fate]]" to negate the attack and force both players to draw a card. If the player did not use the drawn card by the end of this turn, they would [[Victory Condition|automatically lose]]. Nash used Barian's Chaos Draw to draw "[[Glory of the Seven Emperors]]", while Yuma used Shining Draw to draw "Double or Nothing!" Yuma canceled his attack after activating "Double or Nothing!", knowing that defeating Nash would be to sacrifice Yuma's rapport for his enemies, just as [[the Door]] had predicted.

Nash had known he would play "Double or Nothing!", but this action was not predicted. "Glory of the Seven Emperors" would have allowed him defeat Yuma had Yuma done anything else, but canceling his attack resulted in Nash's Life Points becoming 0. Nash encouraged Yuma never to abandon what is most important to him - his ability to believe in others and his pure heart. He mused that he would not witness the future they would create though. The "Numbers" flooded from Nash's body and were absorbed by Astral. Nash told Tori to never let Yuma out of her sight and called Yuma and Astral the best friends he'd ever had. He informed them that he considered this final Duel to be his greatest - and also the most enjoyable. Nash succumbed to his wounds after this, fading away.<ref name="ep143">{{episode|Yu-Gi-Oh!
