Yusei begins his battle against Jakob, using Crow's trap to bring out Stardust Dragon when Black-Winged Dragon gets destroyed. Jakob then activates a trap, which brings out Grannel Attack 3, while reducing Yusei's life points to 2,800. Jakob shows Yusei and the others a twisted future where New Domino City is completely destroyed. Due to Synchro Monsters and Ener-D evolving the world at an incredible rate, a war broke out and the Ener-D reactor eventually exploded, destroying most of the world. The Yliaster trio also unveil their memmories of despair. In the future, they see everybody Synchro Summoning, and as a result of them using Synchro Monsters to achieve their own greedy desires, the Machine Emperors show up one day, and begin killing humans. In the vision, as Lester was running with his parents to safety, a Grannel shot his parents down. Lester in the vision, then wails at the death of his parents, the ones who loved him. Then, Primo reveals that he joined the Freedom Fighters, a group of military people who destroy Machine Emperors, to restore freedom to mankind. He also reveals that he fell in love with one of their number, and they often fought together. When they ambush another Grannel, it retaliates, by shooting down the building, killing his girlfriend in the process. Primo then cries over her death, and when the Grannel comes to kill him, he angrily shoots it down. Jakob then reveals that he was the "last survivor" of the Machine Emperor attack. Then then says that he tried for years to find other humans, but to no avail. In the future, Jakob then sheds some tears over the destruction of humankind. Back in the duel, although the Yliaster trio said that the events the Signers just saw were their memories of humanity's destruction, Yusei refuses to believe that any of it was true. Yusei then brings out Shooting Star Dragon, and manages to destroy Machine Emperor Grannel Infinity, which reduces Jakob's life points from 12,000 down to 3,900. Just then, Jakob activates the Yliaster trio's infinity patches, and then the sky glows red, and a huge green infinity symbol appears in the sky. Jakob, Primo, and Lester then get launched into the sky, towards the huge green infinity. Then, they fuse together to form the true Emperor of Yliaster, Aporia, who is the true form of the Yliaster trio, and then the green infinity disappears. (Lester is his childhood counterpart, Primo his teenage one, and Jakob his form during his old age, and Aporia is the mid-age adult counterpart, who appears at the peak of his life, formed only by the 3 other counterparts fusing.)
