William had successfully obtained the Power Stone. After bidding farewell to the Godslayer, Gamora, he decided to return to his own timeline.
He unleashed the powers of the Space Stone and the Time Stone at the same time. Blue and green light intertwined, and he entered a place like a tunnel through time and space. Before him shone rainbow-like radiance, and he vaguely seemed to glimpse something incredible.
Late at night in New York's Hell's Kitchen, rain poured from the sky. Within the curtain of rain, a red figure battled his enemies. He wore a red combat suit, with two devil-like horns on his mask, two overlapping Ds on his chest, and a pair of batons in his hands.
Inside a silent ancient castle stood a Black man in a black leather coat and dark sunglasses. He gripped two sharp blades as bats before him transformed into vampires. He was a vampire hunter, swinging his swords and cutting down enemy after enemy.
Finally came an entirely new world: a mysterious school. A bald man in a suit sat in a wheelchair; one man's eyes could fire lasers, while a woman's entire body was engulfed in flames, a terrifying phantom Phoenix looming behind her.
A helmeted man floated in the air. With a mere gesture, he could twist and deform an enormous steel bridge...
William had seen such visions while in the Quantum Realm. He had seen the Spider-Verse, Venom, and the world of Men in Black.
He knew that the Marvel universe contained countless parallel universes, and the transdimensional rift in the Spider-Verse had already opened entrances to those parallel worlds. He flew toward the X-Men universe.
He knew that the final battle was about to begin. It was time to bring those two people back.
