(Sonic's POV)

I looked at my hand of cards. Knuckles took one of his cards and he played it.

Knuckles: Changing the color to red.

Tails: Stop changing it to red. I don't have any red cards.

Shadow: This Uno game is stupid.

Sonic: Then why are you still playing?

I heard my scroll go off. I took it out my pocket and saw Ruby is calling me. I answered the call.

Sonic: Yo. What's up?

Ruby: We need you guys over here! We found the scientist's base!

Sonic: We are on our way!

I turned my scroll off.

Sonic: Cmon guys! Let's get going!

Tails: Let's go Sonic!

Knuckles: Time to give the fat cyborg a piece of my fists!

I looked over at Shadow.

Sonic: You coming?

Shadow: ...Fine.

I stood up and grabbed the green gem off the table.

Sonic: Alright guys! Let's help out team RWBY!

(Time skip)

The four of us are running towards Ruby's location. I looked ahead and saw a huge building.

Sonic: So that's the base, huh?

Tails: How much money did it cost to make it?

Shadow: Won't matter. Since I'll be destroying the hell out of it.

Knuckles: Leave the wrecking to me!

I looked around and saw team RWBY looking at the base.

Sonic: Hey guys!

They turned around and saw us. We stopped in front of them.

Ruby: Thanks for coming as soon as possible.

Sonic: No problem.

I looked at the huge base.

Sonic: Whats the game plan?

Weiss: We need to get in there somehow.

Tails: No doubt the place is heavily secured.

Knuckles: I say we just bust through.

Yang: I like that idea.

Shadow: Let's just get this over with. I've got several things I need to get done.

Blake: Like what?

Shadow: Not this.

Yang and Knuckles walked up to one of the walls. They reeled their fists back and punched the wall, busting a huge wall into it. We all stepped inside. We're in a room with three doors.

Knuckles: Knock knock, it's Knuckles.

Ruby: Let's find (Y/N) and get out of here.

Sonic: He can be anywhere in this place.

Tails: Let's split up in groups of two. We'll be able to cover a lot more ground.

Weiss: Good idea.

Blake: When one of us find (Y/N), call everyone else and we'll group up again.

Knuckles and Yang jumped up to the ceiling and punched a hole through it. They went through the newly made hole.

Sonic: That's one way to get to the next floor.

Shadow and Blake went through one of the doors. Tails and Weiss went through another door. I looked at Ruby and she nodded at me.

Sonic: Let's hurry up and save the day.

Ruby: You read my mind.

We walked through the last door. I looked around the room we entered and I saw a camera. It turned and looked at us. Ruby shot it, destroying it.

Sonic: Looks like the Egghead knows we're here now.

An alarm started to go off. Robots came out and looked at me and Ruby. We rushed over at the robots. I kicked one, sending it into a wall. Ruby slashed a couple at once, cutting them in half.

Sonic: Let's blast past these pieces of scrap metal!

I started to charge up energy. A blue aura surrounded my entire body. Ruby turned into rose petals. Ruby rushed over and picked me up, turning me into blue rose petals. I used my light speed attack, making me and Ruby dashed forward at high speeds. We went through the robots and went through a wall. We continued to go through walls. We made it to a huge room. We landed on the ground and Ruby stopped using her semblance.

Ruby: I'm a little dizzy.

Sonic: Where are we now?

I looked over and saw Metal Sonic. He looked at me.

Sonic: Whats up faker? Did you miss me?

Ivo: I know I sure didn't.

I looked behind metal me and saw the man himself.

Sonic: Heya Eggman. We're here for our friend back.

Ivo: You won't be getting him back. I still have plans for him.

Ruby: You give (Y/N) back right now! Or you're going to regret it!

He started to laugh.

Ivo: I'm so scared of two children. Metal Sonic! Take care of the trash!

Metal me nodded his head.

Sonic: We took you out once and we can do it again.

Metal me dashed forward at us. He certainly gotten faster since our last encounter. I tried to kick him away, but he caught my foot.

Sonic: What the?!

He slammed me into the ground. Ruby slashed at Metal, but he dodged and kicked Ruby away.

Sonic: How did you get so strong?

He grabbed me by the neck and tightened his grip. I grabbed his arm and tried to move it, but it wouldn't budge.

Ivo: This is quite the sight. This is the best show I've ever seen.

I looked at the Egghead and Ruby is right behind him.

Ruby: I said you'd regret it.

Metal me let go off me and quickly went over Ruby. I got out my scroll and quickly sent a message to everyone, telling them to come to my location. Ruby jumped up and landed next to me. She helped me up.

Sonic: Thanks.

Ruby: Don't thank me yet.

Ivo: Metal Sonic, finish this now!

Sonic: Now wait. I have an offer for you.

Ivo: What ever it is, I don't care.

I pulled out the green gem from my back pocket. I showed it to him.

Ivo: A Chaos Emerald?!

Sonic: So that's what they're called. Give (Y/N) back and I'll give you this.

Ivo: No. I'll have Metal Sonic kill you and I'll take the Chaos Emerald.

Sonic: Oh... It was worth a shot.

Metal me dashed at us. Me and Ruby put our arms up to defend ourselves. The ground started to break and Knuckles uppercutted through the floor, sending metal me in the air.

Knuckles: So there's the scientist. He's fatter than I thought.

Yang jumped up through the hole in ground.

Yang: Time to take on the robot blue boy.

Ivo: There's more of you here?!

Shadow and Blake came crashing through the ceiling.

Shadow: Chaos Spear!

He shot out a spear of energy and hit metal me. A door opened and Tails and Weiss walked in.

Tails: We got here as fast as we could.

Ivo: No way! I can't believe this!

He reached into his pocket and pulled out a white Chaos Emerald.

Ivo: This sure will be interesting. Metal Ruby!

A pair of red eyes appeared in a dark corner. The Rubybot walked out of the darkness.

Weiss: It's already repaired?

Ivo: Let's see how you all beat my two greatest creations!

Rubybot rushed over and stood next to metal me. Everyone got ready for a fight. We all stopped when we heard a banging noise.

Blake: Whats that?

We looked over at a wall and it started to crack. It broke open and a bunch of dust covered the area.

Ivo: Can you all stop busting through my walls!

Nora: Where are the gems?!

The dust cleared up and team JNPR are there.

Jaune: Hi guys.

Nora is hold four different colored Chaos Emeralds. A red, cyan, purple, and blue.

Pyrrha: We found four of the gems.

Nora: I'd told you I'd find them all!

Ruby: We got the yellow one from the robot of me.

Ivo: So all the Chaos Emeralds are here...

He smiled to himself.

Ivo: Today is my day.
