S01E131: The Beginning of the End

In another dimension, Z-ONE (who has now returned to his original form) shows Sherry a vision of the future, where everything on Earth is destroyed because of a global Ener-D explosion. Then, Z-ONE brings Sherry into the Ark Cradle, which is already emerging into the Yu-Gi-Oh! dimension. That night, the Signers are messaged by the 3 emperors of Yliaster, who tell them about the floating metallic island, the Ark Cradle, where a God called Yliadus (Z-ONE's real name) supposedly sleeps, stating that if they win the WRGP, then Yliadus will awaken and have New Domino City destroyed, but will rebuild it the way the trio wants it to be, which is without the existence of Ener-D and Synchro Monsters. During the next morning, the WRGP finals begin with Jack facing off against Lester, who both bring out their ace monsters, Red Nova Dragon and Machine Emperor Skiel Infinity.
