A crossover between RWBY and Sonic The Hedgehog. What if Team RWBY were invited to Eggman's Interstellar Amusement Park to not only see what he has made but also see what he's plotting. I can imagine the girls having a lot of fun there. I also wonder what power they can use by absorbing the wisps' powers. Let's see...


"YAHOO! Let's go!" A red-haired girl was running aero-plane style as she was entering towards the "Welcome" gate. Six heroes have arrived in a strange amusement park which is set in space. There were four girls; Ruby Rose, Weiss Schnee, Blake Belladonna and Yang Xiao Long, and there were two animals; Sonic the Hedgehog and Miles "Tails" Prower. They came here for one reason, to see what Dr. Eggman is doing with this amusement park.

"You idiot! I told you to stop going off on your own like that!" Weiss shouted angrily while chasing her teammate. Blake looked up amazed to see she's not on her home planet anymore.

"I always wanted to go to space once, but I never thought it'd be like this." Blake said.

"I know right? It'd be like a coincidence that something like this happened!?" Yang smiled.

"Well, you know Egghead, he always makes the most weirdest stuff on the old drawing board." Sonic said looking at the buildings.

"Yep! And this one's probably a new one to us." Tails said with a slight sweatdrop. "Why would Eggman build something like this?"

"To entertain people?" Blake asked.

"You know Eggman doesn't care for others than himself." Sonic said with a disappointed look.

"Ah... good point."

"Let's quit yapping already! I wanna see some rides I can go onto!" Yang cried out as she made a dash through the gate.

"But those can be dangerous! Yang!" Blake called out running after her.

"Oh man! I think I'm starting to like these girls already." Sonic grinned as he dashed as well.

"Sonic! Wait up!" Tails flew to catch up with him.


"Well, well, looks like Sonic has finally arrived in my amusement park." The mad scientist, Dr. Eggman laughed in a secret hideout. "And it looks like he brought the RWBY friends too. Guess I'll give them a warming welcome too, along with the hedgehog.

"Ooh! Are you going to surprise them with a poppers?" One of his minions called Orbot, asked. "And maybe have candy and cake as well."

"No, you idiot! I'm surprise them with a beating of their lives. And just why are you still here? I thought I told you to capture more aliens for the ray."

"Well, we came here to chat up with you. You look pretty bored so we brought a puzzle cube to give you." A minon named Cubot, said showing a Rubik's cube in his hand which was swiped away by his master.

"I'm fine on my own! Now stop dilly-dallying and get more aliens!" Eggman shouted as he pointed them to the door which they went through before it closes. There was silence around the room until Eggman looked at the Rubik's cube he was holding in his hand a starts playing with it.


BGM - Sonic Colors - Tropical Resort Map

"Welcome to Eggman's Incredible Interstellar Amusement Park, where you can enjoy five planets to the price of one!" The sound was coming from Eggman's P.A. Announcements.

"He sure loves to hear his own lips flap, but I gotta hand it to the Eggster, this place is epic." Sonic smiled. They've been looking around the park and saw awesome things, such as the rides, the food, the toys and even a Ferris Wheel. "Everyone and their siblings is gonna want to come here."

"I know, I feel like I want to forget about saving the world and start riding all these attractions." Ruby followed.

"Remember that they are Eggman's attractions. They might not be safe and are probably traps." Weiss warned her.

"Maybe. Though now I'm not sure why we're here?" Tails asked himself. "This place looks totally harmless."

"That's probably what it wants you to believe." Blake told Tails.

"Besides, Eggman plus secretly built amusement park equals evil plot for us to foil." Sonic explained. "Lucky for us he's not very good at keeping things hidden."

"I'm pretty sure this amusement park wasn't meant to be hidden." Weiss sighed. "I mean, it can't be easy to miss a giant floating space amusement park surrounded by planets."

"Still, an evil plot? I don't know." Tails said unsure. They stopped for a moment to take a glorious view at the Earth, their home planet. There were 'wows' and 'whoas' coming from the six heroes's mouths.

"Plot or not, you can't be mad at this view." Yang smiled. "This place is takin' beauty to the next level."

"I know, I'm just surprised that it was so easy to sneak in here." Sonic said.

"Uh, I wouldn't say it was that easy." Tails sweatdropped thinking back before they came here.

Flashback

"Whoa! Where did this tall, tall, tall building come from!?" Ruby asked shocked to what Team RWBY was seeing. The girls decided to visit Sonic's world again and this time they found a building that leads to space.

"And what are those planets up there?" Blake asked as the four were looking up.

"They're Egghead's work, duh!" The girls turned to see their Hedgehog friend beside them.

"Sonic? When did you get here?!" Weiss asked.

"About minutes, I thought I'd say hi when I saw you four." Sonic smiled.

"What brings you four here, today?" Sonic's fox friend, Tails, asked them.

"We wanted to see how things are in your world and apparently, it was good time to see this." Blake answered. "You're saying this is Dr. Eggman's work?"

"Who would be crazy enough to make a giant amusement park up into space with planets surrounding it?" Sonic asked.

"Did you say amusement park!?" Ruby asked with sparkles in her eyes.

"First, he uses water monster to take over the world, then he uses a ray that split the planet into pieces and now he builds an amusement park? How stubborn is that mad scientist?!" Weiss asked annoyed. "Plus, how do you make a amusement park in outer space?"

"Makes me wonder how much money he has to pay all of those, heck, where does he get all the money from?" Yang wondered.

"How about we go and talk more when we got up there?" Tails asked. "We'd be wasting time if we stayed here any longer." The heroes nodded as they proceed to enter the building to use the transport elevator.

Much Later

"Hello, happy people! Buckle up as Eggman's Ultra-Accelerating Space Elevator whisks you to an interplanetary wonderland of fun!" Eggman's P.A. voice came from the elevator.

"I can't believe somebody was dumb enough to leave the keys in this thing! It's like Eggman's begging us to sneak in and trash the place." Sonic said.

"I can't wait to see what's in the parks, rollar coasters, bumper cars, cotton candy, or even cookies!" Ruby squealed.

"Of course, that would be in your mind!" Weiss groaned.

"let's be careful, this is built by Eggman so we'd best be cautious while there's fun." Blake informed everyone.

"M-M-Man, this thing's got c-c-crazy fast acceleration!" Tails shrugged feeling the terminal velocity of the elevator.

"You call this fast?" Sonic taunted.

"Well, maybe the elevator is '2 fast 4 you'." Yang teased. Sonic was giving her a glare as his mood changed slightly. "It was just a joke, OK?! No need to give me the evil eye!"

"This amusement park has been constructed entirely out of a sense of remorse for my past transgressions and is no way associated with any sort of evil plot or premediated misdeeds." P.A. Eggman continued.

"Well, that's a relief!" Sonic said sarcastically as the elevator was almost getting to the station.

"Next stop: the Tropical Resort! There you'll find breathtaking views from our giant Ferris Wheel! Amazing deals at the shopping mall! And constant threat of bodily harm."

"Did he seriously just add that in?!" Weiss shouted.

Flashback End


Tails groaned face-palming after remembering that. "Ugh, just thinking about it makes my head feel like it wants to..." He was cut off by an explosion that was heard behind them. They ran to see what's up and found two of Eggman's shape robots chasing down some 3 odd aliens. Cubot was carrying a net and Orbot was shooting with his laser pistol.

The white alien had a basic shape are that of a sphere with three tentacles, two of which are used as arms. It had one pink eye in the center of their heads, and two very alien-like antennae on top of their heads.

The cyan alien has two permanently narrowed orange eyes. It possess three tentacles stemming from the head, one of which is shaped like a lightning bolt. They also have a spike-shaped structure pointed backwards, sticking out from their head.

"Yee haw! Git along, li'l aliens!" Cubot shouted in a western tone.

"Your voice chip is stuck on cowboy again!" Orbot sighed. "Stop talking and net those aliens!" Cubot was chasing the aliens like crazy, sometimes, he himself was being chased by the aliens for some reason. Orbot was shooting the aliens but began shooting at random places and then sighed as he relaxed, was he programmed to not give a darn about work?

"I'm not sure what's goin' on, but I'm sure of what I'm gonna do!" Sonic said as he zoomed closer to where the robots were. He quickly snatched the aliens before Cubot could and went back to Team RWBY.

"Huh?" Cubot gasped as he saw nothing on the net. He was sure he got the aliens, so why aren't they in the net?

"Hey, what's goin' on?" Sonic asked the robot though he doubt he could hear him. But before anyone could say anything, the cyan alien flew inside of Sonic, much to everyone's shock. The hedgehog started to slowly floating with a cybernetic aura as Sonic started glowing cyan and zoom away fast like a laser. He was drastically bouncing everywhere from building to ground to building again. Team RWBY and Tails were stunned by what they just saw.

"Aaaaaand he's gone." Yang broke the silence.

"What happened just now?" Weiss asked confused.

"The alien just went into Sonic and he immediately flew off, it was almost as if he was given a new power." Blake said.

"I know, he went super fast like a laser!" Ruby commented.

"Uh-oh. Looks like we got company." Yang pointed at a band of Eggman's robots coming towards them. "About time we get some robot smashing." She smirked as she cracked her knuckles.

"Time to get blasting!" Ruby agreed taking out her Crescent Rose in its sniper form. But as soon as she aimed her gun towards the robots, a red alien flew in front of her. "Um... could you please move? I'm trying to-" But Ruby was cut off as the alien flew inside of the sniper rifle. "Wha-!? It flew inside of my Crescent Rose!"

The weapon suddenly starts glowing as a fiery aura was flowing around it, especially inside the hole of the gun. Without notice, the gun automatically fired a bullet which was on fire and looked like it was covered in magma and was heading fast towards the robots. Ruby didn't realise this, causing her to be pushed back far and fall to the ground by the force of the shot (Newton's 3rd Law). The bullet magma was getting close to the robots. The moment it touched one of them, it created a massive explosion made out of red fire which decimated all the robots in one place.

"Owie!" Ruby groaned as she rubbed her bottom. The red alien came out of Crescent Rose and was then flew away.

"Are you alright, sis?" Yang came and asked her worried.

"Yeah, that really surprised me. Huh? What happened to the robots?" She asked seeing robot scraps from a distance after getting up.

"The bullet you fired destroyed them, all of them." Blake answered her.

"Wha-?! Seriously?! Just one bullet?! I don't recall firing though."

"I think the alien, your weapon absorbed, enhanced the bullet and turned it into some kind of missile bullet. When you 'fired' it, it exploded with fire and annihilated all of the robots in a single shot." Blake explained.

"Really? That's so cool! I wanna try that again, if the alien came back..." She sighed when she noticed the red alien is gone. Although, one alien is still with them, it had one eye and a twirl hair on top of it. "Um... hello there." Ruby greeted it.

"$&^$#&^!%$?" The alien began speaking some odd language that none of the girls could even understand it.

"...Anyone got any idea what's it saying?" Yang asked. The others shook their heads when Tails caught up with them. He was carrying some kind of tablet pad and a toolbox.

"Hey, guys. Where's Sonic?" He asked the girls.

"Dunno, he zoomed away like a laser and now he's gone somewhere." Yang answered. "So what's that you're holding there?"

"Oh, this? This is something I was working before you guys came here to visit. This is a hand-held translator I'm working on so I can use it to translate beings who speak a different language like that alien."

"Really? So you can tell what this alien is saying now?" Ruby asked.

"I haven't finished it yet, I just need to make slight adjustments. I'll need to connect the framistatic capacitor to the maximizing modulationizor and..."

'I haven't got a single clue of what he's saying now.' Team RWBY thought with sweatdrop.

"But don't worry, I'll get this working eventually." They were hearing the alien's talking again, too bad they couldn't understand it. "We wish we knew what you were saying, little guy, or gal, or whatever you are."

"You're so cute, I think I'm gonna name you 'Squeak'." Ruby said happily while Weiss face-faulted.

"Don't just go naming aliens like that!" Weiss shouted angrily. Before they knew it, Sonic came back as a laser and turned back to normal in front of them. The cyan alien that Sonic absorbed came out of him and flew away.

"Oh, man! That... was... CRAZY!" Sonic cried out.

"Seeing you zooming everywhere, yeah, I can see why you think that." Blake sweatdropped.

"So did you go somewhere?" Tails asked Sonic.

"Didn't you see?! I absorbed those aliens and got powered up with like, some kind of wild energy! And after a few seconds they'd pop outta me!" Sonic explained.

"Oh, I had the same kind of experience!" Ruby piped up. "There was a band of robots that were coming after us. I was about to fire when one of the aliens flew into my Crescent Rose giving the bullet wild powers that beat all of them up! They pop out of my weapon after that! It was crazy!"

"...I find that hard to believe." Tails slowly said.

"That's because you didn't see them in action." Yang told the fox. "Though you could say Sonic zoomed a-'ray'! Get it?" This earned groans from the rest of the girls.

"%^$%#%&%^" The alien was talking gibberish again, but it still didn't catch anything to them.

"Okay, seriously, we need to find Eggman and figure out how catching these aliens fits into whatever heinous plans he's hatching." Sonic stated.

"And wreck that plan, right?" Tails supported.

"Yeah, that's pretty much how we spend our time."

"Really? What do you do when Eggman's not around?" Ruby asked.

"Oh, you know, run around, eating Chili Dogs, the usual days I do." Sonic smiled.

"I just tinker things so I can figure new things I can make with technology." Tails said.

"Oh, how I wish your life could be easy as mine." Yang sighed.

GL: Here it is! The first prologue with lots of questions arising.

To how Team RWBY know Sonic and his friends, this isn't actually the first time. They actually met in Sonic Adventure which is a couple of months ago. I was actually planning to do RWBY X Sonic Adventure first but this one came first. I dunno why, this one might have the funniest moments. I'll make the stories with RWBY and sonic from Sonic Adventure to Sonic Lost World. It'll be a mess of fun.

Instead of giving RWBY wisps powers to their bodies, I've giving them to their weapons. I kinda feel iffy about transforming into a color power and I think transforming their weapons with color power seems more fascinating. So I decided to give color power to their weapons as change.

I decided to add both wisps from the Wii Version and the DS Version, including the stories so the main story will make sense, including the Nega-Mother Wisp fight.

I hope you like the changes. I'll try to make prequels after this story. See you in the next chapter.
