In this story, it was prophesied that one of the brothers are gonna turn to the evil side. Dream strongly believes that he will never turn to the dark side and that Nightmare is the one who will. He boasted that he's the good guy and evil will never take over him even to the point of eating one of the the black apples to prove it.
So, in this alternate reality, Dream's personality involves being overly-confident and prideful, he thinks so lowly about his brother and always assumed that Nightmare was and always will be up to no good. Nightmare, on the other hand, is humble and kind-hearted. He's actually proud to be the protector of the bad side of the Tree despite what most thinks of him. He always thinks of it as his special purpose rather than a curse."What have you done to me?!" Illusion choked out at his brother who is enjoying seeing him struggle. "Putting you in your right place, of course!" Delusion replied. "This realm simply cant have two heroes...one of us must have to be the villain and that, my dear brother, will always be you". He smiled smugly. "Now, brother, dont kill that innocent creature beside you" Suddenly, one of Illusion's fiery tendrils grab the said creature by the throat and set it a flame. "NO, STOP!" Illusion sobbed as he tried to save the little critter from his own grasp but it was out of his reach. Then it was too late, the creature gave its last shriek of pain as it finally got devoured by Illusion's flame. "Good...You see? No matter what you do, you are always be inclined to do evil" Delusion said as he turn away and retracted his own flaming tentacles going back to his normal form. "Lighten up, dear brother, it's better this way" He said fixing his crown. "We could even get along..." he then started to walk away. "..as Archenemies"
