Hey, guys. I'm so, so sorry about not uploading a chapter earlier. I had a lot of stuff going on, what with work being super busy, as well as me getting distracted by watching other kinds of anime. I apologize for that, and I hope that I don't have a lapse like that again.

By the way, I recently saw a trailer for Lego Dimensions that's pretty cool. It actually has stuff from one of my favorite game series: Portal. You can actually play around in the Aperture Enrichment Center, but even more exciting is being able to play as Chell, the heroine of the Portal games. If this means that there will be Lego Portal kits, then I will buy all of them. No kidding.

Anyways, I won't bother you too much more, so let's get straight to it, then. I don't own RWBY or Sonic. Enjoy!

Outskirts of Vale, near the Forest of Forever Fall, 7:59 p.m.

The sun had just set, leaving Vale covered in a darkness lit only by the moon and the streetlights. Under a light near the edge of town was a gathering of beings that would probably be talked about by the older generation for months to come

The team responding to Eggman's request stood at the designated coordinates, a few miles outside the Forest of Forever Fall. Sonic was practicing his swordplay with Shadow while Yang was watching with interest. Nora and Amy were giggling to themselves, their conversation most likely about the boys they knew. The only motionless being was Omega, but that was because he was in deep conversation with Aeromi deep inside his mainframe.

After Sonic fended off a particularly vicious attack from Shadow, the black hedgehog held out a hand. "We'd better stop. It's almost time for Eggman to arrive."

Yang sat up and stretched a bit. "Thank God, I was getting bored."

Sonic looked at Amy. The pink hedgehog had worry in her eyes, and he had to ask about it. "Amy, what's wrong?"

"Sonic, I'm… afraid," she admitted. "What if Eggman doesn't keep his word after dealing with this threat he mentioned? What if he attacks us when we're all exhausted?"

Sonic was about to say some encouraging words, but Nora beat him to the punch. "I know! We'll break his legs!"

Everyone stared at her fierce expression at a loss for words for a few seconds. Sonic then started laughing, followed by Amy, then Yang. Even Shadow chuckled a little. Omega was the only one not laughing, but they could hear Aeromi's giggles from his body.

Omega moved his arm, pointing at the forest. "Obese being detected, heading from that direction."

Everyone stopped laughing and prepared for the mad doctor's arrival. The sound of maniacal laughter was heard as Eggman arrived in his Egg Pod from the trees a few seconds later. He lowered the pod in front of them. "Aha! Good to see you all! Now, we can get rid of this threat, and I can get back to conquering Remnant!"

Eggman's small speech was soon interrupted by the sounds of guns being drawn on him. Sonic walked up to the pod, Cobalt Shard at the ready. "Alright, Egghead, before we do this, we'll need some more conditions. Specifically, one that doesn't allow you to harm us for at least 24 hours after we arrive at your base. If you don't, well, let's just say we'll let Nora loose." The orange haired girl once again donned her fierce expression.

Eggman put two fingers to his chin, considering this complication. He then nodded. "Very well. If that's what it takes to have your cooperation, then so be it." He then saw Omega and panicked. "I wasn't serious about bringing him!"

"Idiot creator's message seemed urgent, and the option was presented," the robot replied in a monotone voice. "So we took it." Yang stifled a giggle.

Eggman sighed. "Oh, alright. Let's just go." He took out a few small black discs and handed one to each of the group. "These will teleport you directly to my base. I want to at least keep the location a secret for now, so deactivate your GPS systems."

Sonic grinned. "Paranoid about us, much?" Nevertheless, he and the others turned off their GPS systems. Not that it would've mattered.

The mad doctor pushed a button on the dashboard of the pod. "Orbot, Cubot, prepare for our guests' arrival."

"Yes, Doctor." "Yeehaw! Now we can have a real hoedown!"

"So how do these work, exactly?" Yang asked, looking at her disc. There was a small button on the center.

"When I tell you to, just push the button. Are you all ready?"

Sonic did some leg stretches. "Bring it on, Eggface!" The others reported their readiness with less dramatics.

"All right, good. Now, push the buttons in 3… 2… 1!"

Everyone pushed the buttons on the discs at the same time. There was a bright flash, followed by a feeling that their bodies were being pulled apart. They closed their eyes from the feeling and the light. About five seconds later the feeling stopped. Sonic carefully opened his eyes and saw that he was standing in a living room type area that had a long of Eggman-themed decorations. He looked behind him and saw the others, including the doctor himself.

"Well, what do you think?" Eggman grinned proudly.

Amy shook off the dizziness and looked around. "I'm not impressed, Eggman."

He rolled his eyes. "Everyone's a critic…"

Orbot rolled up in front of everyone and popped up. "Greetings. I'm sure you will want to get started right away. Please, follow the Doctor."

"Oo, a ball!" Nora shouted excitedly. She got out Mjolnir. "Who wants to play croquet?!" Orbot panicked and hid behind Eggman. "I'm not a ball, I'm a robot!" he shouted, scared.

"Alright, enough of that. I've got him trapped in the deepest part of my base, but I don't know how long it will last." Eggman started walking into a hallway, and everyone followed him. Nora reluctantly put Mjolnir away and followed him, Amy sitting on her shoulder.

As they walked through the base, they glimpsed parts of Eggman's operations through the windows in the hallways.. Sonic watched as a Beowolf pup was restrained and stuffed into an orb, mostly likely powering a new Dark Pawn. "Pretty big plan you've got going here, Doc."

"Not to mention risky as hell. What are you thinking, using these creatures of darkness?" demanded Shadow.

Eggman glanced over his shoulder. "Would you rather me use small animals? Besides, there are plenty of Grimm on this world, and no one seems to care if I use them as cannon fodder, heh heh," he chuckled. "In fact, I'd say I'm doing this world a favor. I'm decreasing the number of Grimm that you would have to fight anyways. Why not use them for my schemes? It's better than having them killing innocents, riiight?"

Yang and Nora looked at each other uncomfortably. Eggman did have a point in his logic. Since Eggman started using Grimm as power for his robots, the number of Grimm attacks drastically decreased.

Omega's red photoreceptors glared at Eggman. "Your logic is flawed, Eggman. You would use the Grimm-powered Badniks to hurt innocents anyways. No matter what you do that seems beneficial, it's always for your benefit."

"Just like this errand," muttered Shadow. "If there's any constants in this universe, it's death, taxes, and Eggman being a selfish bas-"

"We're here," Eggman interrupted. He stopped in front of what looked like a high security jail cell. The interior was a bare white, and two Dark Pawns were guarding it. "He's in here." He waved an arm into the cell.

Everyone looked through the two-way mirror. "Who's in here? I don't see anyone," said Nora.

Eggman looked in. "What?! Where'd he go?!" His eyes shifted right to left, and he glanced at the robots. On closer inspection, the Pawns were offline. Upon observing this, he started to panic. "No, no, no, no…"

Sonic crossed his arms. "Eggman, if you led us out here for nothing…"

"I swear he was in here!" Eggman thought for a bit, then slammed the intercom. "Orbot, Cubot, where is that outdated abomination?!"

There was the sound of chairs moving around on the other end of the connection. "According to the scanners, he's right next to you," said Orbot calmly.

Eggman became very red-faced. "Not Omega, I mean the other one!" A drop of sweat rolled down his face as he heard Omega's guns loading up from behind him.

Tense seconds rolled by. "He's in Grimm Acquisitions, Boss-man! And he's sure makin' a ruckus! Ah've never seen them like that!"

Eggman turned to everyone. "Follow me, and quickly!" His pod appeared, and he jumped on and hovered quickly down the hallways. The group followed the doctor, Omega looking for an opportunity to deposit Aeromi into Eggman's computer systems.

They stopped in front of a large door, which Eggman was trying to open. "Come on, accept my code, you know it's me!" He slammed a fist beside the keypad. Omega saw a computer outlet near him, and he raised an arm. A cable snaked out from his clawed hand and attached to the outlet, allowing Aeromi into the system. "I'm in," she said in computer speech that only Omega could hear. He spooled the cable back in as Eggman finally got the door open.

Inside was utter chaos. The various species of Grimm that Eggman had acquired were running amok in the room. Some robots were trying keep them under containment, but a few Beowolves leapt into them and started tearing the Pawns to pieces.

In the middle of the chaos stood a solitary figure. He looked like a hedgehog, but a quick glance said that it was a metal one. He turned his head to the new arrivals and snapped his clawed fingers. All at once, the Grimm stopped their rampage. He walked towards Sonic's group, his metal feet echoing in the sudden silence. "Well, well, well… I was wondering when you'd show up, Sonic…" His red eyes glowed ominously. "My loathsome copy."

Sonic's eyes widened as he recognized the voice. He drew Cobalt Shard out of the sheath. "Hello, Metal."

"You don't seem surprised," observed Eggman, hiding meekly behind his pod.

"We met him earlier. Kicked his butt, too!" shouted Yang, activating Ember Celia. The others got their weapons out, ready to fight.

Metal Sonic grunted. "You may have beaten me before, but that was because I was in a machine more inferior than this former weapon." He spread his hands, indicating the Egg ARK as a whole. "Once I've killed all of you, this will be MY base of operations."

Eggman revealed himself from the pod. "And what makes you think that I'll let you do that?"

Metal chuckled and waved an arm at the Grimm. "These Grimm will listen to me." He pointed out his new form, with Deathstalker-like armor plates on it. "It's easy to control them when you absorb the data of the biggest in the packs." He gestured to the group. "Leave the blue one. Kill the rest."

The Grimm leaped forward as the group started firing their weapons. Sonic dashed towards Metal Sonic, and the battle truly began.

Once again, I'm sorry for the late update. If there are any fellow writers following me, I understand why some writers have long breaks between chapters. I can finally sympathize with you.

That being said, work has been tapering off lately for the summer months, so I may have some more energy to write. I'll also be focusing more on this story instead of my Zelda story. It's really hard to write down what you want to when you have one hand on a keyboard and the other on a Game Boy Advance.

Anyways, thanks for reading! Hope to see you in the next chapter!
