Sans looked stunned, as he spoke out.

"What...Sark...aligning himself with the Highest, even though he's a demon, a Highest's enemy!"

Knuckles nodded his head, as he spoke out.

"Yeah, even I can't believe it. But...guess having Rosy stripped from him really made him double down the way that he did."

Sans looked down and clenched his hands into a fist, as he narrowed his eye sockets and Sonic spoke out.

"You're kidding me? All because of Amy!! Knew Sark was terrible, but didn't know he'd be so petty in what he does!! Where is he?!"

Tails then stepped forward, as he then spoke out.

"Well, that is what we intend to find out. We know that they were told by Sark of where he would take him, and we need them to see what sort of information they have in their heads."

Sans nodded his head, while he turns around for a bit, as he then unzipped his jacket, and shows what seems to be the second Phantom Ruby, this one in the form of an upside down triangle, as he spoke out.

"Hope this one can work for me."

He zipped his coat back up, as he then turned around and walks back over to Tails and Knuckles, as he spoke out.

"So where do you plan to take them to see their memories."

Tails looked at the remote in his hand and spoke out.

"Got a machine that is back at Exetior's place. Should be strong enough to be able to handle both Cream and Sally's power. So...let's get moving."

Tails then pressed the button, and everyone is temporarily surrounded by a green sphere, which then rose up, and then slid down, as everyone got transported, even Giga Metal, despite the fact that he is very large in size.

The entire place looks red in varying shades, as Sans and Sonic and the others looked around, as Sonic spoke out.

"Huh...seen this thing when I was still back in my normal body, with Exetior taking over it. Didn't think I'd see this again."

Sans looked and spoke out.

"So where's the machine for all of this?"

Tails pointed at it, it was a pair of machines that have extendable helmets that attach to the head. Sans used his blue magic to lift Cream and put her onto the machine, as metal clasps appeared and are over her hands and feet, while Sage does the same with her telekinesis and sends Sally to the other one, and she too has her hands covered by clasps, as Tails goes to the machine and spoke out.

"And don't you all move. I'll get this done in a jiffy."

However, Tails looked down and whispered to himself unhappily.

"Better not take too damn long."

Tails then began to type onto the computer, as Knuckles turned to Sans and spoke out to him.

"Hey...Sans...how's...how's Julie-Su doing?"

Sans looks at Knuckles and spoke out to himself.

"She's doing fine, I guess. Her and the kid, but they are not happy still seein' ya, especially since you 'did' almost try to kill her when u was taking her to Mount Ebott."

Knuckles looked down and sighed a bit, as he spoke out.

"Yeah, figured she'd react like that."

Knuckles shook his head, clearly not happy how the circumstances went. But as that happened, 3 new voices spoke out.

"Oh, we have some visitors..."

Everyone turned, as Rosy realizes that more demons are coming. Appearing are Robotnik, and Exetior's Amy and Sally. Amy looks and sees her alternate self, and spoke out.

"Woah...Rosy...is that you?"

Rosy looked and nodded her head, as she spoke out to her.

"Yes...it's me."

Sally looks at her and spoke out.

"Wow, how'd you...I thought you were still with Exetior...where is Exetior, though?"

Knuckles then took the turn to answer.

"It's Sark. He betrayed Exetior. He's now going to try and kill him."

This made the others stunned and spoke out.

"What? He's going to kill Exetior? But why?!"

Sans then took the turn to spoke out.

"Mainly because of the fact that he is a sore loser in that he cannot stand having Rosy be refused to be returned to her. Especially since Killer had to be the one to rescue her from Sark. Not to mention...apparently, he decided to make an alliance with the Highest for an unknown reason."

Sally clenched her fist angrily, and spoke out.

"This sort of act is unforgivable! Sark is going to pay for this act of betrayal."

Robotnik, hearing this, then spoke out to the girls.

"Even though he is already a terrible person to begin with. Because let's face it, he always is the worst of the Demons."

Sans shrugged a bit and smiled, as he then spoke out.

"I mean, you're not wrong in this one."

Sage looked a bit at Sans, and as she did, Robotnik took notice of her, as he then almost realized who it is, as he spoke out.

"Wait a minute...are you-"

Sage turned to look at Robotnik, and Robotnik was about to continue to speaking, but then, Tails spoke out to everyone that's present.

"Okay, did it. I found Exetior's location, no doubt that Sark is there as well."

Sans nodded his head, and spoke out.

"Good, but before we do that, we need to get some stuff brought with us, this includes the Chaos Emeralds, which are back at Mount Ebott. We're gonna need then to fight against Sark. And Sonic, along with them, you best take the Silver Sonic battle armor also."

Sonic nodded his head, as Tails spoke out.

"Wait a minute, the Chaos Emeralds are in Mount Ebott?!"

Sans nodded and spoke out.

"Of course they are. They are placed inside of Mount Ebott to try and power up the shield further. But ever since Exetior broke through it, it broke and the Emeralds just remained there, until we needed them again. But now, though, we do need it."

Tails almost looked unhappy, as he spoke out.

"Damnit!! Had we known the Emeralds are there, it'd be useful in making sure that Exetior does not get taken down by Sark!!"

Sans shrugged a bit, as Amy spoke out.

"Do we come along?"

Knuckles shook his head and spoke out.

"No, you stay in case Sark decides to bring in some of his own minions to try and attack the base. After all, I wouldn't be surprised if he had some demons of his own that are waiting for it to be vulnerable. Me and Tails, along with Sonic, Metal, and Sans, we'll be coming along."

As he said that, Rosy then spoke out.

"I'll join in as well. I want to make Sark pay dearly for what he has done to me, for ruining me the way that he did."

Knuckles and Tails look surprised at how confident she sounded, but they nodded, as Shadow spoke out to Knuckles.

"What do we do with Cream and Sally, though? Dark's Cream and Sally?"

Tails looked at them and spoke out.

"Let's just pin them onto many piles of rubble outside. Best make sure that they do not escape and help Sark."

Sans nodded, as Tails teleported everyone back outside, as Silver then all the boulders up, as many as he can, before making them crash down on top of both Sark's Sally and Cream, with Sally top half of her body pinned underneath the rubble, and Cream's bottom half of her body pinned. This made Cream cry out in pain, as she looked up at them with sheer rage in her face. As that happened, a voice spoke out.

"Wh...who are you both doing here?!"

Everyone turned around, as they see both Cream and Vanilla present, with Tails looking at her with distress on his face, and Vanilla looked at Tails and spoke out.

"So...you are the one that killed my alternate self...and left my alternate daughter to fend for herself..."

Tails looked down in shame, as as Vanilla clenched her fist, and Cream looked distressed a bit, as Sans spoke out.

"Hey, Vanilla...as much as I want to let you do this, we have bigger problem right now, and it's very important. You remember Sark?"

Vanilla flinched a bit and spoke out.

"Yes, since I'm from the Mobius he invaded. Why?"

Silver narrowed his eyes and spoke out.

"Sark went too far this time. Now he's betrayed everyone and aligned with some even worse people."

Vanilla closed her eyes and spoke out.

"I am oddly not surprised, considering he is so grotesque and horrible in his behavior."

Sans nodded, and spoke out.

"Well, we need to leave. Sonic, let's go and get the armor and the Chais Emeralds."

As Sans said that, Shadow joins in.

"I'm coming along as well."

Sans looked at Shadow and nodded, as Sans also spoke out.

"Okay, and bring Metal along. Want him to scan as many people he can, so that he can be strong enough to face Sark when he is depowered."

Shadow nodded, and Sans puts a hand on Sonic's shoulder, Shadow putting his hand on Metal's foot, and all 4 of them teleported away, as Sark's Cream hissed out.

"All of you...all of you will fucking..."

As she said that, Sage pulls Cream back and Silver does the same, as Vanilla stepped forward and spoke out.

"I never thought I would see you so tainted and horrible, Cream."

This made Cream madder, as she then raised her head to see that it is Vanilla.

Vanilla looked down...at the daughter that once loved with her back when they were normal, back on their Mobius. But now...seeing her like this...it filled her with great shame. She looked down at her, on the outside, her feelings seem to be cold and disappointed, but deep down...she is sad at became of her beloved daughter, although she dares not show it. She then spoke out to her daughter in a very cold way.

"To think that this is what you decided to embrace. I am so disappointed in you...going along with that monster in his vile ways."

Sark's Cream snarled at her, as she spoke out.

"Who are you to judge me, you bitch?! He brought me back and allowed me to serve him!"

But Vanilla shot that down, as he spoke out.

"No, you serve him because you want to, by your own choice. You did not do that because of permission he allowed you too. Even Rosy here has made her own choices. But to see this from you...my own daughter...it is so disappointing and disgraceful to see this from you."

Sark's Cream snarled and shouted out in a rage, as she spoke out.

"Quit saying calling me your daughter, you bitch!! You aren't my mother!!"

But when she said that, Fream herself ran and kicked her in the eye, making her howl in pain, as she spoke out.

"Do not dare say that to her!!"

Vanilla, however, extended her arm in front of her, as she spoke out.

"It's okay...Cream...I can handle it from here."

She clenched her fist in sheer anger, as Rosy puts a hand on her shoulder, and the both of them stepped back, and Sark Cream hissed in agony, as Vanilla spoke out.

"You are right about one thing...I am not your mother...because the daughter I once knew of and raised...she is dead...and you aren't her anymore. It sickens me to see what you have decided to become, Cream."

Vanilla looked down, and the other Cream held her hand, as Vanilla held onto Cream's to assure to her that she is alright, as Tails spoke out.

"Cream...listen, what I did I-"

But Cream shouted out.

"Don't finish it, Tails. Save it...I don't want to hear it."

After hearing that, Tails remained silent and looked down, as Cream looked up at Vanilla and spoke out.

"Mother I...I want to go with Sans on this. I...I don't want Sans have to deal with this."

Vanilla, hearing this, crouches down and spoke out.

"No, Cream...you shouldn't. You saw what Sark had done to...to her..."

Vanilla points at Sark's Cream, as she spoke out.

"I...I don't want you to become this also."

But Cream shook her head, as she spoke out.

"I won't mother...because Mr. Sans is here. And this time...I have Mr. Sonic to back me up in protecting me also. I have full trust and faith in them to be able to help me."

Vanilla looked down nervously, in fear that her own daughter is resigning to getting killed by Sark...but she closed her eyes and hugged Cream tightly, as she spoke out.

"Just...please don't die, Cream. I don't...I can't..."

Cream hugged her mother from Sark's Mobius, and spoke out.

"I know...mother...I know."

Both Cream and Vanilla hugged one another, and as that happens, Sage looks at this sight, as she looked down at herself, and hugged herself for a little bit, as she thought of the times that she was with Sans, even if it is just a week at best. She has seen how Sans interacts with his brother, Papyrus. She has seen how Sans had interacted with Cream, and seen how he interacted with Rouge, as she then spoke out.

"Such a beautiful bond...a family born out of both love and genetics, and sometimes not both at the same time. I wonder...how much it feels...when I have this bond."

She looked down and now thought to herself for a bit, but she knows that she cannot feel for this one now. Because right now...she needs to focus on the task at hand. She needs to aid both Sans and Sonic in order to take down Sark once and for all.

Unknown Location...

At a different location that is likely in the demon world or just a converted part of Mobius, either Exetior's, Sark's, or just a random Mobius, it is an area that seems to be composed of green pipes and mechanical buildings, the sound of a Buzzsaw was heard, as laughter was heard.

"HAHAHAHAHAHA!!!!"

The one responsible for this laughter...was none other than Sark, and down to a lower part of the ground, is Exetior and Negagen, the latter is knocked out.

Sark smiled arrogantly at Exetior and Negagen, as he spoke out.

"It seems like the tables have finally turned! This is your end, Exetior! You should have thought twice than to not heed my demands and ignore it!! Now you will pay...with your life!!!"

Exetior looks, as he sees the Buzzsaw blade about to cut both him and Negagen into halves. Sark laughed at this, as the buzzsaw is about to come close to the both of them and saw them to pieces. But then...all of a sudden...before it can get close to the 2 demons, the Buzzsaw suddenly stopped. This made Sark confused, as he spoke out.

"What...why the fuck did that piece of shit stop working?' How did it-"

Sark looked up, and Exetior did as well...and they saw someone that they have never seen before.

Sage is shown extended her hand out, as she then raised her hand up and ripped the Buzzsaw out of the way, and sent it elsewhere. Sark looked up in shock and anger, as he shouted out.

"What the fuck? Who are you to dare to interrupt with my execution?!"

As he said that, all of a sudden, a giant silver-shaped claw appeared and swung at Sark, slicing his chest and knocking him back a bit, as a voice spoke out.

"We dare, Sark!!"

Sark looked up to see Sonic appear, inside of the Silver Sonic battle suit.

Needless to say, Sark isn't happy to see Sonic having to appear so suddenly, as he then spoke out.

"Oh, so the original bitch decides to appear to me right now, huh?"

Sonic clenched his fist, as he spoke out.

"Yeah, and he's here to make sure you pay for what you have done!!"

Sonic leapt up and goes to punch Sark, and Sark goes in for a punch as well, but Silver Sonic's punch knocked Sark as far away as possible. Sark crashed into a wall, as Sans teleported between Exetior and Negagen, before grabbing them both by the shoulders and teleported them both behind a rock, far away from Sark, as he then teleported back to the battle, and sees Sark lookong pretty enraged.

"You fucking asshole!! Alright, you're in for it!!"

Sark does a homing in at Sonic, who then catches him with Solver Sonic's own hands.

Using the small thrusters on the feet, Silver Sonic kept grabbing onto Exetior and not letting go, refusing to let Sark attack him. He then threw Sark into a wall, which he then crashed into rather painfully. Sonic then fired Silver Sonic's laser eyes at Sark, burning him as much as he can and causing the area he crashed in to explode continuously. But Sark came back and spins while he flies, and Silver Sonic spins at Sark to try and take him on. The both of them hit each other as Sark and Silver Sonic push against one another to try and take each other down. However, as that happened, all of a sudden, a purple laser beam fired out of nowhere and hits Sark, sending him crashing to the ground. Sark looked up and recovered a bit to see who it is, and needless to say, he was not happy. Because it was Giga Metal, who now decides to attack with a gigantic vengeance. Giga Metal fired bombs at Sark, while Sonic fired missiles from Silver Sonic's arms in order to try and blow up Sark, and Sark did get blown up in the face directly, but he still recovered and retaliated against Giga Metal.

Giga Metal tried to raise his hand to defend, but Sark punched him in the glass chest, breaking it and shattering the Phantom Ruby. When that happened, Giga Metal began to shrink down to size. However...he did not shrink back down to his normal form. This is because Sans brought Gigal Metal inside of the Underground, and he got him to scan other people, such as Cream, Blaze, Tangle, Jewel, Whisper, the Chaotix, Asgore, Muffet, Undyne, Rouge, and E-123 Omega. And due to this, it changed his base form into something else.

When Giga Metal shrunk down to normal size...instead of resembling his normal self...he now has a much different appearance, having 5 very long quills like Sonic with white lines, the arms shaped like sleeves, black shoulder pads, and He also sports a spiky belt with a black cape that protrudes out of the back of his waist. This is not normal Metal Sonic. No...this time, this is a form called Neo Metal Sonic.

Neo Metal Sonic looks up and glares at Sark, as he spoke out for the first time.

"You will pay for your treachery."

Sark looks at Neo Metal Sonic and sneered a bit at him, as he spoke out.

"I'd like to see you fucking try, you hunk of pathetic scrap!!"

Neo Metal Sonic clenched his fist, while Sonic in the Silver Sonic battle suit stepped forward, his fists clenched tightly as he looked at Sark, before both Neo Metal Sonic and Sonic looked at each other. Although they may not like each other and may even despise one another to an extent, they both agree on one thing. Sark must be taken down. And luckily, Shadow, Silver, and Rosy appeared, as they landed around Sonic, as Sark notice of Rosy and spoke out.

"Aw...if it isn't the pathetic, defective garbage herself...hehehehehe...I should have known you would come back. Did you decide to return to your rightful owner?!"

Rosy narrowed her eyes, as she raised her hammer at Sark and spoke out angrily.

"No...I am here to make you pay for what you've done to me, Sark!! You ruined my life for your sick, twisted amusement. This time...I'm gonna do the same to you!!"

Sark looks at her and almost laughed a bit, as he then mocked her.

"Really...you, making me suffer?! How fucking hilarious, since all you do is bitch and cry all the time. You were a coward, and you cannot dare to fight or even talk shit back against me!"

Rosy clenched her fist, as she spoke out.

"Well, that was then, and this is now. This time, you will pay!!"

Rosy then suddenly appeared behind Sark, and swung her hammer, making him crash down to the ground painfully. Sark snarled in sheer rage, as he shouted out.

"How, fucking dare you!!!"

She then flies at Rosy and fires red spikes at her, only for a Rosy to swing her hammer and parry the spikes away. And all of a sudden, Sark suddenly hit a wall of blue energy, as Sage appeared in front of Rosy, stopping Sark from attacking her, as Sans then appeared and stabbed Sark from behind using a trident, as Sans spoke out.

"I think Rosy here's got a 'point' there."

He then swung the trident and launched Sark at Rosy again, who swung her hammer 4 times, the 4th one sent Sark crashing back down to the ground again. Sans then launched Gaster Blasters at Sark, who roared in such ungodly pain, as Sans' karma caused excruciating agony that Sark has never felt before. But Sark teleported out of here, and tried to attack Sans, only for Silver to use his psychokinesis and slammed him to the ground in a painful way. Shadow then fired his Chaos Spears while jumping above Sark, which exploded onto him, as Sark teleported in the air, his wounds regenerating, but then got hit by Cream, who hits Sark in the face. Sans looked in alarm, as Sans spoke out.

"Woah, kiddo, stay outta this one. It's too dangerous! I said just stay hidden and watch, not get into the action!"

Cream shook her head at this, as she then spoke out.

"No, Mr. Sans. I have seen way too much of my friends and family by people like him! Besides...I am done being useless for no reason."

Sans looked unease at this, as Sark snarled. He teleported and tries to grab at Cream, but Sans teleported in front of Cream and grabbed Sark by the hand, as both Sark and Sans glared at each other, while Sans spoke out.

"Keep your hand off of the kiddo."

Sans then made vines erupt, as they wrapped around Sark and swung him to the ground. As that happens, Cream jumps and kicks him hard in the face, sending him skidding to the side, as Sark shouted out.

"You little brat!! I will enjoy fucking your body!!"

Sans felt disgusted, realizing what he meant, as he then fired bones and pierced Sark, as he then spoke out.

"Okay, that is disgustingly. Welp, you're dead."

He then launched fire at Sark, with the fire being similar to a flamethrower in how it is shot, as Sark gets continuously burned by the flames. Sark roared in pain, and Sans narrowed his eyes, but then another fire appeared out of nowhere and a female voice spoke out to Sans.

"Mind if I can join in?"

This made Sans blink his eyes a little bit, and he turned around to see that it is none other than Blaze, who has her hand out. Sans spoke out.

"What the hell? Where did you come from, Blaze?"

Blaze looks at Sans and spoke out.

"I followed all of you here. I figured you would need some help with the situation that you are in."

This made Sans blinked a little bit, but he shrugged his shoulders, as he then summoned some Gaster Blasters and fired them at Sark, doing as much damage as he can to him. Sark roared even louder in the sheer agony of what Sans and Blaze are doing, but he'a now had enough, as he roared and made a shockwave, causing both Sans and Blaze to skid back, and Cream was almost launched backwards, but Sans manages to catch her, as Sark snarled in sheer rage and is about to speak, but Sage fired a laser beam at Sark and he began to skid back from the attack, while Neo Metal Sonic launched Chaos Spear-like projectiles and then Energy Beams from his hands. Sonic in the Silver Sonic suit fired lasers from the wrists and from the eyes to try and deal as much damage to Sark as possible. But Sark began to slowly stand, and eventually sped up and out of the firing beams. He then goes to attack Neo Metal Sonic, who made the black shield and got knocked back, before he goes to attack Sage, who teleported away. Then he goes to attack Sonic inside Silver Sonic, who fired grappling cables and wrapped them around Sark before slamming Sark to the ground. Sark crashed down to the ground, before he then stands up and snarled in sheer rage at this, as everyone gathered around, with Tails and Knuckles having joined in also, and they are now happy with Sark extremely petty betrayal. Tails then shouted out.

"Sark!! How dare you betray us like this?!!!"

Knuckles stepped forward, his eyes flared red, as he shouted out to him.

"It is bad enough that we tolerated your disgusting behavior, but betraying Exetior and siding with the enemies we're against?!"

Sark scoffed at him, as he spoke out.

"He should have thought twice then to let that asshole skeleton keep what belongs to me from me and instead heed my demands!!"

Rosy then stepped forward, as she shouted out.

"Come back to you?! I would never come back to you after what you put me through!! Besides, I'm defective garbage to you, right? That means I disposed myself so you wouldn't have to see me!! And you go with the Highests all just because I'm gone!!"

Sans stepped forward, and spoke out.

"Geez, pal. How petty can you get? You oughta be happy that she's outta your hair. Not be some sort of brat with a temper-tantrum all because a toy you didn't like is discarded."

Sark shouted out in sheer rage of what Sans has said.

"Shit the fuck up, you sack of bones!!! You do not mock me at what I decide to do!!"

Sans then clenched his fist and spoke out.

"On the contrary, I can. And I wonder...that expression you had before...you clearly made a deal with the Highest to join their side. Tell me...what sort of deal did you make that allowed them to enlist you to their services?"

Sark snarled a bit, but smiled.

"Really, it's simple. It is merely to give Exetior's head to one of them, Stitch-Lite, in exchange for keeping my world, my rule, nothing more!!"

Sans scoffed a bit, thinking that what he decided to do is downright pathetic, as he spoke out.

"Shameful for you then, that it will be cut short. Because now...you are so dead."

As he said that, a red glow appeared on Sans' chest, and everyone took notice of it, but Blaze spoke out to Sark, her voice defiant and not wanting him to win.

"That is right, and for your crimes against all of us, and for this act of betrayal in such a callous way, you will pay for what you have done."

Blaze held her hands out, and then, the Sol Emeralds appeared and surround her, as Sonic realizes what she is about to do, as she spoke out.

"Hold it, Blaze. Don't this this sort of thing alone."

Sonic opened the Silver Sonic Head up and jumped down from the ground, and Sans teleported it away, as he spoke out.

"Let me join in."

He held his hand out, and the 7 Chaos Emeralds appeared around Sonic. But as that happened, the Chaos Emeralds appeared began to increase in the spinning range. It first got Shadow to be surrounded in them, then Silver, then Neo Metal Sonic, and then, surprisingly, Cream. Cream looked around in confusion, as she spoke out.

"Wh-Wht?"

As that happened, Sonic looks and smiled a bit, as he then spoke out to her.

"Heh...guess you have that inside of you as well, Cream...welcome to the club."

The Chaos Emeralds spun around the 3 main hedgehogs, Neo Metal Sonic, and Cream, as the Sol Emeralds spun around Blaze. Sans stepped back; with Rosy also leaping beside him. Sage teleported beside Sans to witness what is about to happen. They watched, as the 6 Mobians began to glow brightly, as Sans and Rosy closed their eyes at the very bright shine of light. When the light died down, the both of them looked and they are stunned at the sight that is before their eyes.

Sonic, Shadow, Silver, Neo Metal Sonic, and even Cream, they all went into their super forms, while Blaze goes into her burning form. Although, Cream's super form is different, wearing a white dress with a gold line at the bottom of said dress, golden shoes of different shades, 2 golden rings on each of the wrist, a red tie, and a crown on her head. On both the crown and the tie is what seems to be a Chaos Emerald that is the same color as her brighter fur. Her eyes opened, as they are shown to be red, and Cream looked at her hands, feeling amazed at what she is feeling inside of herself. She smiled, before she looks at Sark with a determined expression, and Sonic floats forward, in which he then spoke out.

"Now Sark...your madness ends."

Sark snarled a bit at seeing that most of the group had went into their Super form for combat, and he floats up a bit and looks at the group, as he snarled in sheer rage.

"It doesn't matter how many of your fuckers there are!!! ALL OF YOU, WILL SUFFER BY MY HANDS!!!"

However, as he said that, unbeknownst to everyone, a certain one-eyes experimental Gap Demon is shown to be present, and looks unamused at the sight.

Pervision looks down at what Sark has decided to do, as he then spoke out, knowing that Sark will not hear him from this far away.

"You have made the biggest mistake to betray Exetior the way you decided to do...Sark. And now...you will pay dearly for this petty treachery."
