Sans is shown to be putting some sort of Liquid Metal of some sort in a sort of fuel injector, and injects it into the Silver Sonic combat suit, as Sonic and Sage are shown to be together and looked up at him, as Sonic spoke out.

"So...you almost done, Sans?"

Sans nodded his head and spoke out.

"More liked, I am now."

He then takes the empty injector out and jumps down to the ground and spoke out to him.

"We got the energy shield in place that acts and shaped around the body of the machine as armor, and now we made some nanobots that can self-replicate and repair the suit in the possibility that its indestructible hide is somehow damaged in a fight, since we are reversing and altering the process of that metal virus that Robotnik had made. I'd say that this gigantic hunk of scrap metal is ready to roll."

Sonic nodded his head, as he made a thumb's up, while Sage flies up and spoke out to him.

"Hmm...I see this suit of armor remaining intact and working as intended in thousands of scenarios, with only very few scenarios that show of it being destroyed."

Sans looked and nodded.

"Well, no surprise there. And this is all the upgrades that I can give it. Still, really hope that it can lost long enough to the very end of this fight that we are in."

Sage looks at Sans with a curious look in her eye. It had been a week since Sage had woke up, and now has began to live with Sans. She had been following Sans since her first day, and is very curious of what is around her, as well as what she is in. Although, she is shown to be both cold and mechanical in her speech, with very little hint of emotion. Sage, although knows that Sans is not a genuine creator of her existence, which he admits since he told her that he simply just finished the original creator's work, she will stayed with him and doesn't even ask him to tell her of her true creator to find him, even though she has every chance to do so and meet him. Even Sans is a bit perplexed at why she doesn't bother to think about it. But he is not complaining, as he simply lets her go along anyway.

Also, he gave the Metal Tails, Knuckles, and Amy to Robotnik, who had been looking for them and took them in to reactivate them. But Mecha Knuckles...Sans activated him and made him work with Mecha Sonic in guarding the Master Emerald, and also acts as Julie-Su's personal guard in a way, especially to protect her and the baby. Sans smiled a bit, but also felt a bit sad that Julie-Su is gonna have to possibly raise the baby without her actual husband. But...even so, he hopes that they can still keep on going and living in the end.

Anyway, Sans looks at Sonic and spoke out to him for a little bit.

"So...anyway, Buddy...since Silver Sonic is finally operational, it's safe to say it is ready to throw down against any highest in the way. But...maybe best use it when you absolute have to and not every time. After all, best keep some of our most powerful weapons hidden from our enemies until the time is right, y'know."

Sonic looked and nodded his head, as he then walked away from the Silver Sonic robot and looked at it, as he then spoke out.

"You know, I never imagined that I would be using a Silver Sonic as a suit again, but one that actually accommodates more with what I am capable of. So...honestly feels amazing to use this sort of thing again."

Sans looked and spoke out.

"Well...the circumstances would have been better of when you'd use that again."

Sonic nodded, as Sage looks at Sans, as he then spoke out.

"Anyway, let's go back outside...while in Mount Ebott, that is. Think we've done enough for the day."

Sonic nodded, as he spoke out.

"You said it."

Sans puts his hand on Sonic's shoulder, and both Sans and Sonic teleported, with Sage also teleporting, as Sage and Sonic looked around to see that they are in Snowdin. Sans smiled a bit, as Rosy spoke out.

"Sonic..."

Sonic looks and sees Rosy walking up to him, as she then hugged his arm, with Sonic smiling down gently at her. Sage gawked a bit, curious at this display, as another voice spoke out to Sans.

"Mr. Sans!"

Sans blinked and turned, before he smiled and saw Cream coming at him, as Sans bent down and picked her up, as he spoke out to her softly.

"Heya kiddo. How've you been doing?"

Cream smiled a bit, as she spoke out.

"I'm doing great, Mr. Sans! Been having fun with Mother!"

Sans smiled and spoke out.

"Nice...and I already said you don't have to call me Mr. Sans. Mister makes me sound so old."

Cream looks at him, as both Cream and Sans chuckled a bit, with Sage looking down and holding her left wrist, not exactly sure what she is feeling, but...for some reason...she cannot help but feel like she wants to experience this sort of body that Sans is giving to the rabbit. However, as this happen, the sound of an explosion happened nearby, as this made Sans, Sage, and Sonic turned to the source of it, and Sans spoke out.

"Not good. Cream, best get back to your mother. This might be bad."

Cream looked and nodded, as she then flies away as fast as she can, as Rosy still is present, and could almost tell who has arrived, as Sans snapped his fingers and teleported everyone outside, now in what appears to be Green Hill Zone, which is bloodied as covered with bodies, as they looked to see who has arrived.

It was the Sally and Cream of Sark's Universe, and judging by the look on their faces, he can tell the they are not here for a welcoming hello. Sans looked unamused at the sight, as he steps forward and spoke out.

"That expression on your faces...you both seem desperate to take something, huh?"

Sark Cream scoffed a little bit, as she stepped forward and spoke out.

"Of course, captain fucking obvious!! We're here to take back who belongs to him!!"

Sark Rosy, having a guess of what she meant by that, stepped back, and clenched her fist, as Sonic gets in front of her and spoke out.

"Well, you're wasting your time. Your master has nothing to gain from taking Rosy. So why don't you both come crawling back to where you came from?!"

Sally stepped forward, and spoke out to them in a hushed tone.

"I'm afraid that we can't do that...he may hate her, but still prefers her as belonging with us."

Rosy narrowed her left eye, as she spoke out.

"Oh I'm part of you and Sark alright, part of it enough to torture me and consider me garbage. Sark doesn't need garbage like me as being part of your group, so you should be happy that I am no longer with him and the rest of you!"

Sark Cream narrowed her eyes, as she stepped forward and spoke out to Rosy.

"And I'd be happy to, bitch, but Sark still think you do not belong anywhere but with him and him alone!" So quit your whining and return, or we will make you!!"

Rosy glared at Cream and spoke out.

"Says the one whining herself. And it seems you never learned your lesson from the last time I beat you. Allow me to give you a proper reminder...of what I'll do you."

Sark Sally clenched her fist, as she raised her head and spoke out.

"If you will not come along with us quietly...we will make you come along by force."

Rosy clenched her fist, as Sonic stepped forward, and spoke out.

"She ain't coming back with you both! If you want to take her, you'll have to get past us first!!!"

As he said that, Sans and Sage also moved forward and Sans spoke out.

"That makes it 2 of us."

Sans and Sage looked at the duo, with Sans smiling sinisterly, and Sage looking coldly at them, as Sans spoke out.

"The both of ya, I think I'd say that you made the biggest mistake attackin' us out of the blue like that. So...perhaps it is time I gave you both an idea on what I'll do to ya."

Sage has red pixels floating around her hand, as she then spoke out.

"You made the biggest mistake arriving here for such an unreasonable demand...and dare threaten the ones that I am loyal to...now you will pay the price."

Rosy took out her Piko-Piko Hammer, looking almost angry, as she spoke out to to them.

"I allowed my life to become suffering because I was too pathetic and scared to stand up to Sark...too scared to stand up to you both. This time...I'm done allowing you to do this to me. I'm taking what remains of my life back...and there is no way you are stripping this from me again."

Cream snarled a bit and spoke out to her.

"So be it!!"

[There should be a GIF or video here. Update the app now to see it.]

Cream then fired some spikes at Rosy, as Rosy then swung her hammer at then, breaking them impact, as Sonic then jumped into the air and tries to do a homing attack on Cream, who then jumped out of the way. She then goes in to attack Sonic up close, but Sonic moved out of the way fast. However, Sonic felt the shockwave of each punch, which really shows that this Cream's physical prowess, due to her demonization, had been enhanced greatly, as he kept jump and moving out of the way. Sonic then kicked her away, and shouted out.

"Sonic Wind!!"

All of a sudden, a blue gust of wind appeared and knocked Cream back, as Cream snarled and fired spikes at Sonic, only for Rosy to break them with her Hammer yet again. She then runs forward and swung then at Cream, who dodged the hammer, before she leapt forward and tried to kick Rosy's head off, only for Rosy to duck down and, in such a great burst of speed, swung the hammer and hits Cream, sending her crashing to the ground, making a crater. But Cream leapt back up and snarled at her.

"You'll pay for that, you sl-"

Before she could finish, Rosy kicked Cream hard and sent her up into the air, as Sonic spoke out.

"Hey, mind battering me upwards?"

Rosy smiled, as she readies her hammer, as Sonic does a spin dash and moves towards Rosy, who then swings her hammer upwards, sending Sonic into the air, as Sark Cream, who herself is also in the air, looks and sees Sonic above her, who then kicked her as hard as he can, sending her crashing back down to the ground, making a pretty big crater of sorts, as Sonic landed down next to Rosy. However, as that happened, Cream leapt back up and snarled, as she spoke out.

"You fucking Bastard!! I'll give Sark your head as a trophy for him!!!"

With Sans, he is shown to be firing his Gaster Blaster at Sark Sally, who is somehow able to move out of the way, despite the fact that she cannot see. It is almost as though she feels it coming. Sans then launched bones, and Sally kicked them away, as she ran to attack Sans. She tries to kick and punched Sans, but he constantly gets out of the way, dodges to the side, ducks, and jumps, all worn his hands in his coat pockets, as Sans spoke out to her.

"Is that best you can do? Sark needs some better toys to send."

Sark Sally did not appreciate this, as she goes in front of Sand to punch him, only for Sans to grab her fist and hold it in place, both of their arms shaking, as Sage then launched some rocks and parts of the ground at Sark Sally, who is launched away by the attack. She also fired a laser from her hands together, as Sally moved to the side and looked up at Sage, as she then tried to attack her, but Sage simply went through her, almost like a ghost, as Sally landed down onto the ground and looks up to 'sense' a Gaster Blaster firing at her, only for her to dodge and get out of the way quickly. Sally turns her head at Sans and sort of glares a little bit, as she than ran at him fast, as Sans also ran at her, but this time he summons a Trident and swings it at her, yet Sally jumps and dodged out of the way, not wanting to get skewered by the weapon, as Spears then fired at Sally, which she dodges quickly. She looks at Sans and clenched her fist, as she spoke out.

"You are already such an annoying pest."

Sans looks at her and spoke out to Sally.

"And you are insanely delusion and stubborn to think that you'll be able to win against me."

Sally clenched her fist and looked a bit madder, as she spoke out.

"I'll show you what it means when I am Sark's second-in-command."

She then rushed at Sans with a burst of speed, and tried to punch him, only for Sans to move out of the way without care, as he then used his blue magic to send her flying away and made her crash into a cliff of sort, only for her to jump back and try to punch him, only for Sans to make a scythe and tried to slice her arms off, yet she then jumped onto the weapon to keep her arms intact. When she landed onto the ground, Sans launched fireballs at Sally, who then dodged out of the way, as she goes to Sans and punches him, only for Sans to make a trident and blocks her punch with both weapons in a defensive position. Sans was pushed back a little bit, as he looks up at Sally with narrowed eyes, and he spoke out to Sage.

"Hey, Sage...best I take this one on my own. Mind you can step out of the way for a bit?"

Sage looks at Sans and nodded her head, as she then vanished temporarily into some light blue pixels. Sans looks at Sally, as she then goes to punch Sans, only for Sans to dodge out of the way, as Sans then tried to stab her with the Trident, only for Sally to jump back, before trying to kick him, before Sans duck down and Sally had missed him. Sans looks at Sally, as Sans decided to think of idea, because it is something that he kept on his pocket. He was about to fish it out and use it, but all of a sudden, yellow projectiles appeared out of nowhere and exploded onto Sally, sending her back and launched her away in pain, as a blue aura is then summoned around some rocks and boulders, and they are launched at Cream, causing her to jump back and fly away. A voice then spoke out.

"Mind if we can join in?"

Sans and the others looked up, Sage also appearing, and they see that Shadow and Silver are coming down, with the both of them landing to the ground, as Shadow looks with a smile on his face.

"Heh...normally, I wouldn't attack kids...but for your case...I'll make an exception."

Cream snarled a little bit at this, as she screamed out to him.

"Who are you calling a kid, you asshole!!"

Shadow smirked wider, as he spoke out.

"You, I'm calling you kid!"

Cream got enraged at this, as she shouted to him.

"You're pissing me off!!!"

Cream then fired some spikes at Shadow, who then shouted out.

"Chaos Spear!!"

The yellow projectiles fired and launched at the spikes, as some of the other spears are heading towards Cream, as Cream jumped out of the way, only for the spears to explode and send her flying backwards, as Shadow skates towards Cream fast, before grabbing her by the leg, and slamming her down to the ground all over the place. But Cream kicks Shadow's arm, which surprisingly hurts, which made him throw her away, before he then used Chaos Control to appear next to Cream and punch her down. When both Cream and Shadow landed, Cream flies up and began to get up close to fight him. Surprisingly, for a kid of her build, Cream's own punches and kicks somewhat hurt Shadow in a way whenever her blows made contact with his skin, but Shadow was faster, as he began to kick, punch, and even head butt Cream on the face, sending her back and with a somewhat bloody nose. Shadow smiled dangerously, as Cream snarled with sheer rage. She jumps up, as she goes straight at him.

With Silver, he is launching rocks and debris at Sally, who is getting out of the way as fast as she can. But Silver then launched some boulders, and Sally had to kick and punch them away as far as she could. Sally looks at Silver, as he then flies in towards her, and kicks her hard, yet Sally raised her arms to block the attack. Despite this, however, Silver manages to push her back. He then flies upwards, but Sally goes in to try and grab his leg, so she can tear it off, only for Silver to use his psychokinesis onto her, in order to send her crashes back down to the ground. Sally, however, stood back up from the ground, hardly worse for wear, but not looking very happy, as she raised her head, her facing directing to Silver, who has his arms crossed.

The others looked and saw that the 2 hedgehogs are surprisingly doing well against them. But not wanting to have this be kept up, they all turned to each other and nodded. They decided that they need to end the fight quickly, not wanting to continue it. However, as the others goes into step in and help the 2 Hedgehogs, all of a sudden, a blue blur from above crashed down in front of the groups, which made them both stop. But Sans and Sonic could already tell who this is, since they encountered this one before. The smoke cleared, as the figure rose up, his back facing them, as he looked at the fight.

Metal Sonic then appeared, and needless to say, he looks as though he is finally repaired, now back to full power, and now able to move normally, now that both of his feet are together, and his arms again. Metal Sonic looked, as he began to scan both Shadow and Silver's powers for a little bit, and he clenched his fist. However, he then turns to look at Sans, and Sans got back, as he prepares to fight against him, but then he began to glow a cyan color and is unable to move, as Metal Sonic then fished into Sans' pocket, and pulled out a Phantom Ruby, the one that is Icosahedron in shape, as Sonic blinked and spoke out.

"What...you had a Phantom Ruby this entire time?!"

Sans looked and spoke out.

"Was still practicing and trying to figure it out how it works first. Didn't want to, say, accidentally kill you guys with it."

Sonic and Sans than turn back to see Metal Sonic, as red and yellow electricity began to spark all over, in which he prepares to integrate the Phantom Ruby into his being. Sans and the other stepped back, as Sage prepares to make a shield in case, and then, Metal Sonic began to glow, and everyone closed their eyes due to the scene shining bright. After that...the glow died down, and everyone looked to see what has happened. And they are stunned at the sight.

Metal Sonic has now changed into Giga Metal, and needless to say, he is insanely huge and more bulky, with a larger torso and a smaller head. His metallic quills on the other hand have grown longer and now extend down his spine. His ears and nose have also grown longer, while his eyes have become a lot narrower, being little more than a red line. His arms are likewise more massive and end with sharp claws on his hands. He also now has yellow bolts on his cheeks and a yellow cannon below his chin. His shoulder plates have become larger and longer as well, with their coloration having changed from gray to blue. They also have several cables attached to them that extend underneath them. now that he has integrated the Phantom Ruby on his chest for his new form, encased in glass. Metal Sonic looked down at the 2 demon duo, and fired his mouth cannon, launching bombs at the both of them. They both tried to get away, but they got blown up by the bombs because Sans launched them with his blue magic, which made them collapse to the ground. And then, Metal Sonic got close and deciding to unleash his most damaging blow.

Giga Metal fired a purple laser at the girls, as they are sent flying back from the blast, as well as severely burnt and charred from it. Sally and Cream tried to get up, but because they were too busy with fighting against the group, they tired themselves out. As they struggled, Sans snapped his finger and vines wrapped around both of the demon girls, as Sans spoke out.

"Okay, I think that's enough of that. Nice one, Metal...I guess."

Metal said nothing, but Sans didn't care, as Sage looked at Sans and spoke out.

"What are you going to do with them, Sans..."

Sans looks at then and spoke out.

"Simple...kill them."

He raised his hand and prepares to fire his Gaster Blaster, but then...a voice spoke out.

"SANS, WAIT!!!"

Sans stopped and he turned to look and see that some demons have arrived.

It was Tails and Knuckles...their Tails and Knuckles, have appeared before them. And it seems Tails finally recovered somewhat from what Sans had done to him. Sonic looked at the sight and spoke out.

"Tails..."

Tails heard Sonic and turned, as Sonic gripped Rosy's hand and looked at him. Judging by the look on his face, it's obvious that Sonic knows what he had done to Vanilla, and Tails looked unhappy, sad even, realizing why Sonic is lookong at him, as Knuckles spoke out.

"Sans, don't kill them!!"

Sans looks at Knuckles with narrowed eye sockets, and spoke out to him.

"Why shouldn't I?"

Knuckles looks at Sans and spoke out.

"We need them...because their master had went against Exterior's deal and took him down and sent him elsewhere so that he can be killed."

This made Sans' eyes widened, as he spoke out.

"What?"

Tails looks at Sanse and felt frightened at the sight of him, mainly because he did not forget what it is that he had done to him the first time they met, when Sans stabbed Taiks over and over with a sadistic grin and a cruelty that was close to Sark, but nevertheless, Tails still took the opportunity to answer.

"In other words...Sark had betrayed Exetior, and is about to make an alliance with the Highest!"
