Meanwhile, at Metallic Madness Zone...
Administrator: Sugou certainly fought in a very sloppy way. And I feel bad for what he has done to the child.
Dr. Robotnik: That kid with those dual blades sure showed him. Well, it doesn't matter now that we have other half of the people on the kill list as prisoners. But with the factory destroyed, we'll have to go to the backup plan.
Dr. Cortex: Indeed we must.
Bowser: What is the backup plan?
Dr. Robotnik: This was actually a last resort, but given that we have no other options, we will have to do it.
Meanwhile, inside the cells, two little kids, a boy in blue armor, a man with a bandana, a ninja man with blonde hair, a tall lady with glasses, a group of teenagers, a swordswoman in red, a green dinosaur, a kid with a yellow rat creature, and a swordsman in blue sit down, talking about stuff.
Yoshi: Yoshi...
Heart: Is there really no way of us breaking out of here?
Yumi: We've tried everything, and it would seem the cells can only be open from the outside. Even brute force will not work.
Aegis: Our chances of escape are none. Unless someone comes to help us.
Minato: We've wandered inside a Sonic game and now we're held as hostages.
Junpei: Yeah. Can't believe we got kidnapped by Eggman.
Ash: So you guys know this Eggman? Who is he?
Yukari: Well... He's a fictional video game character in our world. But it seems like in this world, he's real.
Pikachu: Pika...
Ash: Interesting...
Heart: Well, it's really great to see you again, Mitsuru. Same goes for Akihiko, Aegis, and Yumi.
Mitsuru: Yes. We are surprised to find both of you in a place like this.
Minato: You know those two?
Akihiko: Yeah. It's kind of a long story.
Yumi: If you're all here. Does that mean Ragna, Narukami, Team RWBY, and Hyde are here as well?
Ken: Narukami? As in Yu Narukami?
Fuuka: We haven't even seen them yet, so we can't say for sure.
Pyra: You seem to recognize one another.
Marth: Are you friends?
Yumi: We are.
Ash: It's nice to see you guys go a long way. Just like me and Pikachu here.
Pikachu: Pikachu!
Minato: Sure is.
Bayonetta: It would seem that three of you came here just recently.
Mega Man: You mean me, Snake, and Raiden?
Bayonetta: Yes. How did they catch you?
Snake: We were trying to rescue you all, but we got captured trying to do so.
Raiden: And now we're stuck here.
Mega Man: I hope that Cardinal and Orimura will get my distress signal.
As they were talking Heavy Gunner comes walking down the hall, sweeping the hallway while carrying Heavy Magician in a wagon playing Apex Legends on his Nintendo Switch.
Heavy Gunner: Why do I have to get stuck doing this?!
Heavy Magician: Hey, I mean you were supposed to guard the bomb factory, but it blew up thanks to Sonic and those interloper kids.
Heavy Gunner: Oh yeah. But that doesn't explain why you're sitting down on your rusty bum playing Rocket League.
Heavy Magician: Heavy King told me to supervise you. That's why.
Heavy Gunner: Aren't you gonna help me out here?
Heavy Magician: Nope. This is your problem. You still got a whole 6000 trash bags to take out. Including the ones in here.
They look to see a bunch of full trash bins which so happens to be a lot more than they can count.
Heavy Gunner: Grrr...
Heavy Magician: So get to picking them up.
Heavy Gunner: Oh, I'll pick them up alright.
The mischevous gunner grabs a trash bag and pours all the trash inside on Heavy Magician.
Heavy Magician: HEY!
Heavy Gunner: BAHAHAHAHAHAHA!
Heavy Magician: THAT'S IT! YOU'RE GONNA GET IT!
Heavy Magician starts throwing trash at Gunner.
Heavy Gunner: Oh! You want it?! You got it!
The two heavies start a trash fight, throwing garbage at each other, and all of the prisoners watch.
Heavy Gunner: YOU STINK!
Heavy Magician: LOOK WHO'S TALKING!
Minato: I could go for some popcorn right now.
Akihiko: You've read my mind.
Yumi: Is this really necessary?
Junpei: Oh yeah. We gotta have some good music for this.
Heavy Gunner: Luckily I got some good music.
The Gunner puts on Shipping up to Boston by Dropkick Murphys
Heavy Gunner: Okay. Time for the real fun to begin!
Heavy Magician: Let's do this!
The magician throws a bottle of expired milk at the Gunner, who dodges it. But to their bad luck, the bottle hits the Administrator in the face just as she approaches.
Heavy Gunner and Magician: Oh no...
Administrator: What in the world is going on here?
Heavy Magician: Uh... It was him!
Heavy Gunner: What?! No! He did it!
Heavy Magician: Nuh uh!
Administrator: Enough!
Junpei: They're totally in trouble.
Administrator: You are lucky that I'm not the one commanding you. But I'm sure that Dr. Robotnik would be very mad if he were to see such a mess here. So I suggest you both clean this place so he doesn't find out.
Heavy Gunner and Magician: Yes Ma'am!
Administrator: Good. Also, we will be executing the backup plan soon at Quartz Quadrant.
Heavy Gunner: What is the backup plan?
Administrator: We will be using the Phantom Ruby to imbue Tabuu with energy so that he may leave Subspace. But there is a chance that it will destroy everything within a 50 mile radius. That's why we have no other options since we have no more bombs.
Heavy Magician: I see.
Administrator: Now then. I must be going now. And clean this place up.
Heavy Gunner: Yes Ma'am. And watch out for the...
The Administrator accidentally hits a growth beam and grows really big. Her head breaks through the ceiling.
Heavy Gunner: Size beam's...
The now big ex-pontifex puts her hands on her hips and sighs with her low-pitched voice.
Administrator: Goodness. Now I think the Doctor is sloppy as well.
Meanwhile, outside Metallic Madness Zone, Sonic, Tails, Sora, Donald, Goofy the Shiba siblings, Mari, Mayumi, Team RWBY, Ragna, Hyde, Yu, and Joker get ready to move in to save the prisoners.
Tails: Okay. Miss Orimura and Miss Yamada said that the distress signal is somewhere around here. This must be where the Subspace Army has the rest of their targets held captive.
Tatsuya: It's a relief that they're alive.
Ragna: You think we'll find people we know?
Joker: There's only one way to find out.
Blake: I hope they aren't facing the same treatment that Yui did.
Sonic: I'm sure they're not. Even Robotnik's not that cruel. Unlike Sugou.
Weiss: I don't think we need to mention that man's name again. He was way more than a scum.
Yu: So. Are we gonna see Super Sonic right now?
Sonic: Uh, I don't think we need the emeralds right now. They're back at the base.
Yu: Okay.
Sonic: Alright! Let's go!
The whole team charges into the zone, trying to get through the traps and badniks.
Tails: The detention wing should be around here somewhere! Let's keep going.
As they were moving on ahead, a red laser beam shoots down at Miyuki and Ruby.
Miyuki: AH!
Ruby: KYAAAHH!
Tatsuya: MIYUKI!
Yang: RUBY!
The beam causes the huntress and the first high magician to shrink and get tiny.
Tails: Oh yeah. I forgot about this.
Tatsuya: Miyuki?
The two shrunken girls speak with their squeaky voices.
Miyuki: B-Big brother? W-What's going on? Why are you so...
Ruby: W-Why is everyone so huge?
Hyde: Uh. We're not huge.
Sora: Yeah. You both shrunk.
Sonic: Yeah. We completely forgot about this.
Ragna: What's going on?
Tails: Well, basically, this zone has these size beams that shoot down from the ceiling. The red ones shrink and the white ones grow.
Donald: And that red beam shrunk them.
Suddenly, Yang and Mayumi run to pick them both up.
Yang: OH! THEY'RE BOTH SO CUTE!
Mayumi: I KNOW! I JUST WANT TO KEEP THEM!
Miyuki: S-S-Saegusa-Senpai!
Ruby: B-Big sister!
Sonic: Uh, hey ladies. Shouldn't we be going right now?
Mayumi: Aww...
Yang: Fiiiiiine...
Weiss: We should keep going. Though, I would like to pet them later on.
Yang: By the way little sister, we're gonna have to dress you up in a kimono. And show you to Oscar.
Ruby: EEP!
Blake: I'm sure Yui-chan would love to play with little pixie Miyuki. She's even more cuter now that she's tiny.
Miyuki: Oh my... This is humiliating.
Meanwhile, at the command room...
Ganondorf: We have intruders!
Dr. Robotnik: Curses! Did they find out about the prisoners?! No matter... We'll let Heavy Gunner and Heavy Magician take care of them. I'm also sending in Metal Sonic, Bowser, and Dedede.
As a loud thump comes in, they look by the door to see the really big Administrator with her arms crossed.
Dr. Robotnik: Huh?!
Administrator: I suppose you have a way to fix this. Do you?
Dr. Robotnik: Sorry about that.
The whole team arrives at the prison wing. Once they do, a white beam hits Ruby and Miyuki, making them grow back to normal size.
Ruby: Oh! We're back to normal size!
Miyuki: Thank goodness.
Goofy: This is the prison wing?
Tails: Looks like it.
Sora: Okay then. I guess it's time to set them free!
Sonic: Alrighty then! Hello there people!
All of the prisoners look to see Sonic and his friends.
Yumi: Ragna? Hyde? Yu? And Team RWBY as well?
Minato: Is that Joker?
Joker: Long time no see, Minato.
Yu: How are you all doing?
Heart: I can't believe you're here!
Ruby: I know! We really missed you all!
Sonic: Seems like we got some familiar faces here.
Junpei: I don't believe it! It's really Sonic the Hedgehog!
Joker: Believe me. We were surprised too.
Tails: We received the distress signal and we came here.
Mega Man: Great! Thank you so much!
Sonic: Okay! Let's get you all out of here!
?: Oh they're not going anywhere! And neither are you!
Just as they were about to release the prisoners, Heavy Gunner and Magician, along with Metal Sonic, Bowser, and a fat penguin dressed in red and gold with a hammer show up.
Bowser: We're gonna take you down, here and now!
Sonic: I feel so touched right now. But you know what? We're gonna take YOU down.
Sora: Okay. Let's set them free!
Sora points his keyblade at the cell with Mega Man and opens it up, releasing him.
Mega Man: Thank you so much!
Bowser: GRAAAHHH! THEY'RE RELEASING THE PRISONERS! STOP THEM!
Donald: We'll keep them busy, Sora! You get the rest of them out!
Sora: You got it!
Sora starts opening up the other cells.
King Dedede: No!
Sonic: You wanna get him? You have to stop us first!
The villains look to realize that they're completely outnumbered.
Heavy Gunner: We are so dead.
Joker: You ready to go, Minato?
Minato: I sure am.
Sonic: Okay buddy! You still got the subwoofer?!
Tails: You know I do!
The two-tailed fox puts on Reach for the Stars (Re-Colors). And with everyone free from prison, they all finish up the fight.
Sonic: Let's finish this!
Hyde: Grye Vortex!
The spiky haired kid with the red sword creates a tornado, making the villains fly across the room. Then, Ragna charges ahead with his sword.
Ragna: Carnage Scissors!
He uses a distortion skill on them, draining a bit of their life force.
Bowser: Oh boy...
Minato: Orpheus!
The blue-haired teen summons his Persona, which unleashes a fireball at their foes.
King Dedede: Hot! That burns!
Yu: Izanagi!
Yu's Persona unleashes a Lightning attack, paralyzing them.
Bowser: Can't... Move!
Joker: Arsene!
Joker's Persona then unleashes a curse attack on them launching them up in the sky.
Heavy Magician: I didn't have my coffee yet!
Then, Heart starts charging up her fist.
Heart: Iron fist punch of love!
She throws in a powerful punch, sending them flying back.
Yumi: This is where you will fall.
The girl in a white kimono takes out two fans and spins around, making an icy tornado, freezing them.
Metal Sonic: (Beep Beep!)
Ash: Now Pikachu! Use Thunderbolt!
Pikachu: PIKAAA... CHUUUUUUUU!
The yellow rat creature fires an electric beam at them.
Bowser: This is too much!
Pyra and Marth move in and swing swords at them. Then, Mega Man, Snake, and Raiden fire weapons. And Bayonetta summons a giant demon fist, punching them to a wall.
Miyuki: Inferno!
Miyuki sets the foes on fire with her magic.
King Dedede: Not again!
Yang: Okay Ruby. Go for it.
Ruby: Right.
Then, Ruby's eyes begin to glow, and a storm of rose petals begin surrounding the whole area.
Bowser: Now what?!
Ruby: HYAAAAAAAAHH!
The single swing of her glowing Crescent Rose knocks them back. Finally, Sora points his keyblade up in the air, and Donald raises his staff, and Goofy raises his shield, and the trio creates a big ball of light that takes down all of the foes.
Bowser: Oh... boy...
Heavy Gunner: Wha...
Sonic: You guys seem tired now. Must be the thunder.
Finally, Sonic starts charging up his spin dash.
Sonic: Here lies the idiots of the Farting Army. Rest in Peace, thunder!
He releases the thunder and hits the Heavies and the rest of them with his overcharged spin dash, sending them flying away from Metallic Madness Zone into oblivion.
Bowser: SHUUUUUUUUT UUUUUUUUUUUUUUUUUUUUP!
They disappear into the stars.
Tails: Way to go, everybody!
Mega Man: It was nothing. Thanks for your help.
Sonic: Not a problem. Now let's get out of here and go back to West Side Island.
Snake: Right. But we have a situation.
Tatsuya: Situation?
Tails: What kind?
Raiden: We'll explain it when we get back. And thanks for helping us. By the way, you're Sonic, aren't you?
Sonic: That's me.
Minato: You're the actual Sonic? You're a video game though.
Goofy: I guess some of you are from the same kind of world as Joker and Yu.
Fuuka: Well, we are. Just from different times than them.
Sonic: Interesting.
Ruby and Heart give each other a hug.
Heart: I missed you guys so much!
Ruby: Me too! It's been so long!
Yumi: I'm glad all is going well for you.
Weiss: Same goes for you.
Ragna: Everybody's back together it seems.
Hyde: You're right about that.
A group of Robot Bees, Beetles, and Dangos start approaching.
Sonic: Alright! Time to move! We're outta here!
Everybody: Right!
