First chapter here is pretty rushed, but that's just to get the ball rolling. Expect better in the future.

...

Team RWBY is in a bind. They're now on a speeding train, seconds from crashing their way into Vale with hundreds of Grimm on their tails thanks to the efforts of the White Fang. With little time, Weiss shares a smirks with Ruby, and encases their team with ice to protect them from the force of impact.

That's when whatever Powers That Be decide to to give the laws of physics a day off.

...

It's an average day in Station Square, the sun is shining, the wind is blowing, the birds are birding (as is evident all over one car parked under a telephone wire), and the kind folks there are milling about their business.

Suddenly the ground starts to rumble, and the steps to the train station explode outwards. Remnants of train cars fly out onto the streets as what can only be described as four comets of energy surge into the air; One red, one white, one black, and one yellow.

Pedestrians scream as thy scramble to safety, lest they be crushed under a few tons of trainwreck. The comets of energy swipe around one another for a while before the red one blasts down into the ground, the others spiral up before scattering in seperate directions, flying beyond the horizon.

Amy Rose had been on her way to Twinkle Park nearby to get a schedule for upcoming events when this all happened. Like the other observers she's stunned at first, and then curious. Getting a sense something important is going on Amy climbs onto the train wreckage, eyeing where the red comet had blasted its way through the side of a train car. She summons up her hammer, and slowly approaches the hole.

Inside she spots a dazed Ruby who blinks a few times at Amy, trying to figure out if she really hit her head that hard. Ruby waves shyly, "...Hello...miss... Pink creature..."

Amy frowns, "Pink creature? Haven't you ever seen a hedgehog before?!"

"Sorry!" Ruby gets to her feet, and climbs out, noting how nimble she is for someone who's hallucinating. She looks around at the people staring at her, humans mostly with the occasional weird animal thrown in. "Uh... Where am I miss hedgehog? This doesn't look like Vale."

Amy wants to put her hammer away, but she notices Crescent Rose all folded up on the back of Ruby's hips. She decides to keep the hammer out in case it's a weapon. "My name's Amy, and you're in Station Square."

Ruby blinks, "Station... Square...? I've never heard of that city."

Amy doesn't see how that's possible, this city has been famous ever since the incident with Chaos. She sighs to herself as she lowers her hammer, "Are you from another world or something? Weirder things have happened here..."

Ruby rubs her head, "I'm pretty sure I just got a Cuncusion if I'm talking to imaginary pink hedgehogs." Her eyes go wide as she starts looking around wildly, startling Amy. "The White Fang! The Grimm! Yang?! Blake?! Weiss?!"

Amy is about to ask what she's talking about when she hears sirens in the distance. "Uh... Maybe we should go."

"No," Ruby says as she starts to search the wreckage. "I have to find my team! The Grimm can't be too far behind, you're all in danger!"

Amy's eyes go wide when she hears this, and looks back at the hole in the train station stairs. Then she blinks a few times, "Uh... Hey, look."

Ruby looks up, thinking that Amy spotted one of her teammates, and then follows her finger to the stairs. There's no tunnel, just a solid cement crater. Ruby is thoroughly confused, "What? But-"

She's cut off as police cars speed up, surrounding the wreckage. She even spots a black armored van with the letters GUN painted yellow on the sides. Ruby is starting to feel afraid as the officers pour out of their vehicles, guns drawn.

"GET DOWN ON THE GROUND, HANDS WHERE WE CAN SEE THEM, BOTH OF YOU!"

Amy is agast, but drops her hammer as she raises her hands, "Excuse me?!

"Amy?!"

Amy turns her head just in time to see her hero Sonic land on the roof of a police cruiser. She smiles at him, and he looks seriously confused, "Amy, what's going on here?"

"That's what I wanna know!"

Sonic waves down the officers aiming their guns at Amy. They know him of course, and he explains she's with him.

"What about the other one," one officer asks.

Sonic shakes his head, "I don't know her... Amy?"

Amy shakes her head as GUN officers take away Ruby's weapon, which one officer has a little trouble lifting, and arrest the Huntress in training. Ruby looks at the two hedgehogs sadly as she's escorted into the the armored GUN van, and taken away.

Amy retrieves her hammer which vanishes in a puff of smoke before she turns to Sonic. "Sonic... We need to talk."
