Prologue: Amazing Genesis

Mobius, Green Hill Zone…A few years ago

A lone Moto Bug is minding its own business in the lush green, busy rolling hilltops of Green Hill. The badnik moves around on its one wheel and wonders what it should do next. Then it heard something break from afar. The sound of the sound barrier breaking. It looks towards the direction of the sound and sees large dust clouds approaching, all being led by a young blue hedgehog with a round belly. Before the Moto Bug could even blink, it was quickly destroyed by the hedgehog's speed, releasing the bird that was trapped inside the robot.

"Excuse me! Sorry! Pardon me! Hehe." The young-sounding Sonic the Hedgehog smirked. He runs on wooden bridges and spins through loop-de-loops, and soon encounters more badniks in the forms of wasp-based Buzzers, the bee-ing Buzz Bombers, and crappy Crabmeats. "Seems we still have some badnik stragglers. I could use some action." The light-blue hedgehog grinned. In a span of a five seconds, he spin dashes the Crabmeats and spin attacks the flying robots out of the sky, landing in front of the explosion he caused with a smile.

"Robuttnik needs to make some robots that are a bit challenging," Sonic joked while speeding through the treacherous caverns, "Haha. Ro 'butt' nik. Eggman hates it when I call him that. That's what he gets for having a stupid name." The child speedster collects some golden rings while destroying more badniks, hopping off a few springs to the upper area to finish off the remaining animal bots, releasing real animals trapped inside. "Think that's all of them. Should probably head home. Tails and the other Freedom Fighters must really miss their favorite hero." He joked.

Sonic leisurely jogs as he makes his way back home. As he does, a loud explosion is heard from the distance, causing him to suddenly brake and stop. "Huh? What was that?" He asked himself. He looks around, wondering where the sound came from.

BGM-Sonic Generations OST-Cutscene 1

"Hmm. Guess it was nothing." He shrugged and keeps on running.

Unaware to the blue blur, a chaotic purple portal has opened in the sky. Huge sharp claws cling out of the portal as a ghostly humanoid-like monster is seen coming out of it. This mysterious beast has a body made up of purple smoke. It has no legs and a wide chest. It also has a dark, low-set face with two horn-like protrusions on top of it, blue-glowing eyes, and a blue-glowing mouth with several sharp teeth. And lastly, various gears float behind its back.

The giant creature roars as it charges up a purple sphere and releases a massive pulse across Green Hill Zone and the entire world. Sonic stops and turns to the sky, "What is…" as everything starts to go white.

Remnant, Patch (9 years ago from the present)

The sounds of a strolling wagon disturb a cloudy, night forest filled with towering trees shedding their leaves. A young eight-year-old girl with orange bows holding her blond pigtails, wearing a light brown shirt with a belt wrapping her waist is seen dragging the wagon on a long winding path. The wagon contains what appears to be her little six-year-old girl half-sister in a crimson hood, sleeping soundly in the wagon. The blond child looks exhausted, panting with every step while trying to ignore the minor cuts and bruises on her body. After walking for what feels like hours, the young siblings arrive at a worn-down house. The blond girl takes out a photo from her pocket and looks at it to check if she's in the right place. After putting away the photo, she hears low growls coming from within the house. Beastly red shapes start to glow from the darkness, slowly walking out to reveal three dark wolf-like beasts called Beowolves, creatures of Grimm. The blond girl lightly gasps in horror, too petrified and too exhausted to move or shout while her little sister is still sleeping in the back of the wagon. The wolf beasts leap into the air, ready to devour their young prey, but then, the sound of a gun-scythe follows the sight of them, and what seems to be an instant, all creatures of Grimm were cut into pieces by a caped warrior with dark spiky hair holding a large scythe.

"Uncle Qrow!" The blond girl finally speaks.

Qrow turns around and hurries to his nephew, putting his hands on her shoulders. "Yang! Ruby! Are you two alright?!" He asked them.

The young Yang nods, "We're fine! We're fine! Ruby's still sleep."

"Good," Qrow says as he stands up, "What were you doing here? Your father called after he found out you disappeared from the house!" He asked, displeased by his nephew's reckless action.

"I was looking for mom… "my" mom." Yang answered.

"Raven…" Qrow said under his breath so she won't hear him, then shakes his head, "But that's not an excuse to drag your sister here! You two could've been killed!" He said, visibly angry

"I-I…" Yang stares her sad eyes to the ground, ashamed that her brash actions almost got them killed.

"Let's get you back home, but we ain't done talking about this." Qrow said as walks past Yang.

BGM-Sonic Generations OST-Cutscene 1

As the young blond turns her head up, she sees something appear in the night sky. The same purple portal that appeared in Mobius now shows itself on Remnant, bringing back that same ghostly entity that attacked Sonic, now hovering over the forest.

"Uncle Qrow?!" Yang exclaimed as the scythe-wielding Huntsmen turns and stares at the mysterious beast.

"What the hell is that…" Qrow asked in utter shock.

The ghostly beast lets out a monstrous roar that's so powerful it almost blows away the whole forest. Qrow was caught from one of the shockwaves, sending him flying to a tree, instantly knocking him unconscious.

"UNCLE QROW!" Yang shouted. She turns back to the purple monster as it charges up the same purple sphere that devastated Sonic's World. It releases a massive purple shockwave across the whole planet that causes everything to turn white. Yang could do nothing but hold onto her sister's wagon tightly in an effort to shield her from the incoming extinction wave. The little Ruby's silver eyes blink a few times as she slowly wakes up, oblivious to the fact that she, her sister, and everything else in the world has been captured by a white light.

Earth, Nueva York (About 100 years after the present)

BGM-Spider-Man: Shattered Dimensions OST-Malicious Wings

It's the year 2099 in this futuristic Earth. Technology has advanced so far that everyone is riding speedy hover-cars and, most, if not all the buildings in the city used to be called "New York City", now called "Nueva York", are so tall it can touch the sky. In between the sky-touching buildings is a costumed man swinging through the city from what appears to be a white web. His high-tech costume is mostly blue with red highlights, which includes the area where his eyes are and the large red spider on his chest that partially resembles a skull. The suit also features red spikes on each of the arms. This web-slinger seems to be swinging away from something, swinging over a laser beam shot by a cop on a hover-bike, accompanied by more cops on hover-bikes and a flying car shooting more lasers at the webhead.

"Spider-Man, you are under arrest! Surrender now or we'll to use deadly force!" One of the cops offered the futuristic web-slinger.

"Like you already weren't!" Miguel O'Hara, the Spider-Man of the year 2099 quipped.

The cops proceed to fire multiple lasers at Spider-Man as he effortlessly dodges them with his incredible spider reflexes and agility. 'The Public Eye. Alchemax's corrupt police force. It's always a shockin' time running to these guys.' He said in his head, narrowly avoiding another laser shot. 'Watch it, Miguel. How 'bout how finish these guys off before you continue monologuing.'

He swings over more lasers and attaches a webline to one of the hover-bike cops to web strike. "Why don't you guys chase actual criminals? That way you wouldn't spend your time getting your butt kicked by me." He quipped as he uses his insane spider speed to zip over and instantly knock out each cop from their bike, then web zips to the flying car's hood. "Here's your stop!" He quips as he punches through the hood, causing it to smoke and descend rapidly. "And here's mine!" He attaches a webline to a building and swings away from the Public Eye.

"Think I lost them." Spidey said after swinging for a few minutes. He jumps from his webline and sticks his feet and hands to the side of a building. "You gotta love the festivities of 2099. It may not be much, but it's all mine to protect. And I won't let anyone destroy it." He said. Then, he feels something, something eerie crawling up his skin, "That's unusual. My Accelerated Vision's picking up something, but what is it?"

BGM-Sonic Generations OST-Cutscene 1

He turns his head to a large building with the name "Alchemax". Hovering above the building is the same portal that appeared on Mobius and Remnant, bringing back that same ghost-like monster that done something to those worlds. "What the shock is that thing?! And why is it hovering over Alchemax?! What are they up to?!" Spider-Man asked himself, thinking Alchemax is behind this. He launches a webline and begins swinging towards the mysterious beast, "Only one way to find out!"

The beast performs the same world-ending shockwave on this world, swallowing all of Nueva York into a white void. "It's sucking up everything!" Spidey commented on the situation, looking at his surroundings to see everything is turning into white. He swings at full speed towards the beast, hoping to stop it before everything is lost. He launches another webline, only for it to casually fall down as there's nothing left to swing on, leaving Miguel with no other choice but to free-fall into the white void. "WHOOOOOOOOA…" He screamed the light swallows him up too.
