Elsewhere...

Gaster is shown to be walking down a corridor of some kind, as his right eye flared, and his left eye flared purple. Gaster is feeling a lot of pent-up rage from what Bete had done, and now...now he is going to make sure that she pays dearly for what she had done to his kind, too all of the monsters that she had killed, all of the humans that she had killed, and how much she had denied the possibility to Coexistence between the 2 species. He continues to walk, until he saw something. It is Bete, and she is ready to strike down her killing blow on Toriel. And lying down onto the ground, was Asgore, who has his chest burnt, almost as if Bete was responsible for the flames by baiting Toriel into attacking Asgore. Not wanting Asgore and Toriel to die like this, he than summoned a dark blue saw from one of his hands, which was able to amputate her arm off, as Bete was in shock at what she had felt. She than looked around, and saw Orange dots around her, as they than exploded, sending her into a wall.

Once Gaster appeared out of the entrance, 7 red hands appeared and circled behind him, as they than fired like mini-guns, the blasts tried to strike Bete, but Bete blocked one of them, with one of them making a large home near her. She than took the chance to go inside of the hole and out into the open.

Asgore barely spoke out one word.

"Why?.."

Gaster than looked outside of the hole, as he sees Bete going behind a wall, as Toriel than spoke out.

"Gaster? Where are you going-"

But Gaster interrupts her, as he than spoke out to her.

"You can do more for him than me. For his sake, at least pretend that you care about monsters this one time."

This made Toriel stop, before she than looked at Gaster. With Bete, she held her stomach, as she than spoke out.

"What is HE doing here..."

As Bete snarled out, suddenly, a purple glow was behind her. She looked, and saw that Sans has arrived. He chuckled a little bit, as he blasts Bete into a wall, and Papyrus than appeared next to Sans, before Bete went out of the wall, and clearly frustrated, spoke out.

"This is what's sent to stop me? A jester and his lackey? Is that all you had? FINE THEN! This time I'll take your brother's soul! YOU TWO DON'T SCARE ME!"

She than attempted to attack the brothers, only for Gaster to hit her and send her to a wall. Gaster looked and saw that Sans and Papyrus are there, as Papyrus waved. Sans stepped forward, as Sans spoke out to him.

"Heya."

Gaster was a little bit conflicted, but he than smiled, as Papyrus wrapped his arms around them both, as one big happy family. Bete recovered, and she than looked to see the skeleton family, as she than spoke out.

"tch...You got me trapped in a chain...But a chain is only as strong as it's weakest link."

Bete than charged at Papyrus, as she went past Sans and Gaster. But Papyrus is no longer as weak as he once was, as he sends her flying into the air, and he pumped his fist, proud that his training is beginning to pay off for him, in being able to stop and defeat Bete Noire. She than lands into a building, before she is than hit by a Duality Hand, and than hit by a Gaster Blaster, which sends her into a wall of a building, which she launches out from.

Bite tried to pierce Gaster's head, but Sans stopped her with his blue magic, as he sends her to a wall, which hurt her. She than landed onto the ground. Not wanting to bother fighting them, she than fired some arrow-looking projectiles at a wall in order to block them off.

The only walls than began to fall down, as Bete ran away. But the Great Papyrus will not allow her to flee that easily. Bravely, he began to chase her, dodging rubble, before leaping up to go over a wall of debris, before blocking Bete's way out. But this made Bete attack Papyrus, who was able to dodge 2 of her blade attacks, but his scarf was sliced by her arm blade. But before Papyrus can react, he is than but by an attack from Bete, which sends him slamming into a wall, and he crashed into it, knocking him unconscious. But when that happened, Bete is now in between Sans and Gaster, as they fired their Gaster Blasters at Bete, who than raised her arms just to stop it. She felt focused at first, but she than felt the HATE within her take over, as she Chan screamed in pure agony at the HATE Overtaking her body, as she made a shockwave that pushes Sans and Gaster back. When Gaster regained his baring, he than was prepared to attack Bete, but she than spoke out.

"STOP RIGHT THERE!!!!"

Gaster looked, and he saw that Bete had wrapped hat hand around Papyrus' body, and than, she began to clench her fist, as Papyrus' body began to crack and break, with Gaster being unable to do anything about it, and Bete is taking a lot of sadistic pleasure in the fact that Gaster is helpless to do anything to stop Bete from trying to kill his youngest son, who he is trying to protect so much.

As Bete continued to crush Papyrus,

Sans than came out of nowhere and blasted Bete with a smile on his face, a smile that is insane and filled with Madness. He than blasted her with a purple blast of energy, and sends her into a building, as Bete got hit with the full might of his power.

As Sans looked at Bete, Gaster than spoke out to Ppayrus, who is injured onto the ground.

"Papyrus!"

Sans turned, and saw Papyrus' shoulder had been cracked, as Gaster spoke out to him.

"Papyrus! Hey. Papyrus...Stay still."

He than held out his hand, and he than used his green magic to heal his wounds. Sans looked shocked and stunned. But he than smiled, as he turns to Bete Noire, as he than began to speak out a line that he had not said in a very long time.

"It is a beautiful day outside...birds are singing, flowers are blooming...in days like these...kids like you..."

He than clenched his fist, as Fire, Spears and Tridents appeared above him, before he than spoke out to her.

"SHOULD HE BURNING IN HELL."

He than launched then at Bete Noire, as she than began to try and do all she can to dodge and avoid the attacks as much as she can, before she than hse she down fireball to counter the ones Sans made. She than saw that Sans is in front of her, a Trident in his hand, as he tries to stab her in the face, which she was able to avoid. She than went behind Sans, and used her scythe to try and slice his back, but Sans avoided the scythe quickly. And now, Sans is facing a problem. Bete, in this new form, and the fact that she has absorbed countless human Souls, is now slightly more faster and stronger than Sans himself in a physical way. Because of this, Sans is now at a serious disadvantage, and he needs to react to her as fast as possible.

As Bete avoided Sans' Trident, he than ran forward, as he than tried to grab her.  It Bete avoided it, and she jumped into the air. Big mistake, as Sans held onto one of Undyne's spears, and stabbed her in the stomach, before reeling her back into his position, and slamming her down to the ground. He than use his Blue Magic to repeatedly slam her onto the ground and the wall of the building, as she felt a lot of pain when this happened. Pellets also formed around Bete, as she than felt pain when they struck her at the same time in the torso, which hurt her immensely.

But Bete is still getting up, just like before, and Sans frowned a tiny bit, before smiling again, as he than spoke out.

"I've had enough."

Sans than made a Gaster Blaster, which he teleported onto, as he than rose up high into the air. Of course, he thinks that her special power is ready, which is why he will use only a small fraction of it for her to take, as he spoke out to Bete Noire.

"Listen kid, I'm tired, you're tired, they're tired. Let's just end it right here, okay?"

Sans smiled, as he than summoned a bunch of blasters, but did not use his Gaster Blastermination. And this is because he wants her to take the bait. Of course, Gaster does not know of the plan that Sans has, and thus, with no knowledge of it, and Bete having no knowledge of what Sans is thinking of either, Gaster shouted out.

"SANS!!!! STOP!!!!"

But it was too late, as the Rhabdophobia activated, the Gaster Blasters taken, and now, Pink-Eyed Blasters are all over the place, and aimed at Sans, as this is what Sans had wanted. But just before he can do anything about it, 2 of Gaster's Duality Hands held onto Sans, as they glowed Green. The hands cracked, and once they were done, the Hands shatter, making Gaster cry in agony, as Papyrus shouted out to him.

"GASTER!!!"

He than ran up to him, as Sans teleported to them both, not wanting for this to happen. But he than friend back to Bete, who made a type of disgusting smile on her face.

Bete held her hand out, as she than fired the Gaster Blasters, in her hopes to try and end Sans and his family. But the thing is, Sans did not use as many of them at once as she thought. He did not even use his Gaster Blastermination. All he used were a smaller group of Gaster Blasters. So, as she fired, Sans used his special attack, and even more Blasters appeared, as he than fired it. As the 2 Blasters countered each other, Bete and Sans struggled with all of their might to try and overpower one another. But because Sans summoned more than expected, he was able to slowly and eventually, he was able to overpower Bete, blast her into the wall of a building, which fell right on top of her.

Sans smiled, as he than saw that she got hurt. And because she used her Rhabdophobia up, she is now going to have even more trouble than ever before. But he than didn't smile, as she than stood up, and than, all of a sudden, fired an attack that sped up to...not at Sans, but at Papyrus, her blast hit him, which made him hurt, before she sped up to Papyrus, scythe in her hands, as she aimed at his neck, ready to decapitate him, with Gaster nearly getting ready to join in on the kill that Bete has sword them both.

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

It is at this moment, that made Sans' eyes widened, as time seemed to stop. He than began to reflect on everything. He reflected back on the very first genocide route, when he did all that he can to make Frisk change back to who he once was in the past. He began to reflect on how he had to witness his brother's death happening again and again, his head being decapitated, and his skull being stomped and crushed under the foot of Frisk, when he was still bad. And more importantly, he reflected on the fact that he had once been forced to kill Papyrus, along with all of the monsters in the Underground, all in an effort to try and put a stop to the human and their constant resetting of genocide and death. He had gained so hard in order to gain a happy ending, and Bete, she was going to ruin what he had worked so hard to accolade. Not again...not again...NEVER AGAIN!!!"

Before Bete to swing her scythe, Sans went in front of the 2 skeletons, and blocked with his trident, as Bete did not expect that to happen. She looked at Sans, and saw that his eyes are now differ. They are of cruelty and ruthlessness and sadism as before, sure, but there is an entirely different shine in his eyes. Now, it is of pure rage and hatred to Bete, as his eyes are now wide and his mouth is as still in his smile, as Sans than sends her back with his blue magic, sending her crashing down into the ground. She than began to slowly stand up, as she than looked to see Sans is now incredibly furious, as he than spoke out.

"How dare you...try and kill Papyrus, my brother."

He than began to walk to Bete, as he smiled a little bit wider, before he than spoke out to Bete, in a calm voice.

"How dare you."

He than made his left eye flare purple, as his hands glowed blue, before he than spoke out to her.

"You have crossed a line...for the late time. Now you will pay dearly, Bete Noire."

As Sans had said that, Gaster began to move forward as well, his face looked just as angry at Sans, but he is not smiling. He is simply looking at Bete, with a blank, expressionless look now present.

He looks much older than he appears to be. Bete narrowed her eyes, and glared, as she reassured to herself, which Sans can hear within her mind.

'It's alright. One of them is too tired to fight anymore. These 2, it will be simple enough for me."

Gaster than stopped walking, as he glared down at Bete, before speaking out to her in one word.

"Come."

This made Bete confused, and Sans can hear her thoughts inside of her mind.

'Come?...Is he underestimating me?...'

Bete felt angry, as she snarled, before she than spoke out to him.

"I beat you once...I'll do it again!"

She than disappeared behind both Sans and Gaster, as her scythe is up in the air, now with a much more larger blade covering the normal blade, and she glared a little bit at Gaster.

She than charged at Gaster, but he than made his hands green and covered them in shields, catching the blade. This made Bete's eyes widened, as Gaster looked behind her, his red eye staring at her, along with his hands turning Red, and the hands blasted her backwards and right into the ground.

But when that happened, the ground began to crack, and both Sans and Gaster looked around, and they saw that the ground began to sprout out pink spikes that are curing down at their position.

It didn't take long for Sans to figure it out. This is Bete's doing, because within the smoke, was Bete, as she did this new attack at then. Bete smiled sinisterly, her eyes pink, as she surrounded her fingers around Gaster and Sans. But Sans has something of his own. Before the fingers could crush them both, Sans summoned vines from the ground and wrapped them around her fingers, before tearing them off, which made Bete flinch, as she retracted her hands, and she looked at how the fingers had been forcibly ripped from her hands. And than, 5 purple webs appeared, as she is than wrapped around, and Sans than began to spin her around, making her a bunch of bindings, which she had crashed into and damaged, before he than swung them down to the ground.

She than looked up, she was a little bit injured from the collision of the buildings, as she stares up at Gaster and Sans, and they are all glaring at her menacingly.

Bete was scared, her hair looking more pink than before. But as that happened, Yellow Hands than appeared and began to rapidly fire at her. Sans even summoned Pellets that he got from Flowey in order to join in with the Yellow Blasts that Gaster is using from his hands.

Not wanting to get hit, Bete ran as fast as she can, and she than changed her arm to a shield, so that she can defend against it all, while Gaster glared at Bete with slight irritation. After they are done firing, and Bete removed her shield arm, Gaster's right eye began to flicker purple, as he than spoke out.

"Is that all?"

Than, Sans felt something in his own soul, as if he is being drained of energy a little bit, but he is still powerful enough to attack as Gaster than clenched his right hand into a fist, as he than spoke out.

"Than...it's my turn."

Gaster liked emotionless for a little bit, but he closed his eyes, and it slowly turns to frustration, and than, Gaster's face turned into an expression of pure rage, as he roared similar to that of a demon. Gaster's roar is immensely powerful, which shook this part of the city that everyone's in, as his 2 eyes and the holes in his hands became purple, and than, Gaster had done something that nobody, not even Sans, expected from him. Suddenly, 7 hands, 2 larger hands for Duality, and a very large Gaster Blaster appeared right above Gaster.

Gaster has than summoned his most powerful technique of them all, Polychromatism, entirely composed of 7 hands, 2 larger hands for Duality, and a very Large Blaster Gaster Blaster behind him, as the cherry on top. The right Duality is red, the left one is cyan, and the Blaster's eyes purple. This is Gaster's most powerful technique, as Gaster sends in one of the Duality hands, as he than shouted out to Bete.

"YOU WON'T ESCAPE THIS TIME!!!!"/❽︎✡︎⚐︎🕆︎ 🕈︎⚐︎☠︎❼︎❄︎ ☜︎💧︎👍︎✌︎🏱︎☜︎ ❄︎☟︎✋︎💧︎ ❄︎✋︎💣︎☜︎✏︎✏︎✏︎✏︎❾︎

And before Bete knew it, her legs and torso are pulled apart from each other, before a sickening rip was heard, as Bete's shrieks of agony were heard by both Sans and Papyrus, and too Sans, it felt like music to his ears. Than, Gaster clenched his fist, as he summoned purple spikes to prevent her from healing any faster, as well as Sans using vines to pierce her body, and one of Gaster's duality hands punched her down to the ground hard. This made Papyrus feel pain, along with Sans, but Sans does not care, as both Gaster and Sans summoned a blast on Bete, as she shrieked into the air, her screams ar e filled with fear, the very trait that she weaponized against the Monsters and Humans, now having turned against her.

Papyrus and Sans felt their souls half full, but Sans continued to endure, as he stood up, and raised his hand, and summoned Gaster Blasters.

The Polychromatism behind Gaster glows red, as he is ready to use all of his power on it, and Sans, deciding to join in, summoned his own Gaster Blasters, as he joined in along with Gaster to try and kill Bete.

Gaster and Sans fired at Bete, although Sans had stuck her first, as Gaster and Sans began to kill Bete off for real. And when Sans blasted and began to kill Bete, he can feel new powers erupting inside of him, his powers are growing stronger, as he continued to Blast Bete to oblivion, along with Gaster. But as they continued to do that...

"GASTER!!!!!"

This made both Sans and Gaster stop, as they heard Papyrus' voice, causing them both to turn around and see what is up, only to see Papyrus in pain, as Gaster is using Papyrus' soul to activate his full power, along with Sans, who is not bothered by it. This made Gaster stop, as he ceased his attack, and Sans eventually did stop as well, as Bete's body looked awful, almost looking decayed.

And needless to say, it is not a pretty sight, as Gaster fell onto his knees, and returned the magic to both Sans and Papyrus, as their souls went back to full health once more. But for Sans, after that happened, he felt something.

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

His LV went up. He checked his stats, and he saw it. His LV is now at 20. His HP is 660,950, and both of his ATK and DEF are at 9999. He than felt his new powers. He now has most of Bete Noire's powers. He kept her mind-reading, her hallucinations, her spears having been fused with Undyne's, but he also now has her Magic Blasts, which are the triangular shaped projectiles, her Magic Sense, and now, he has been able to obtain her Scythe of Fear, which he feels is even stronger the Trident itself, and his ability to manipulate fire having been upgraded and becoming more powerful than they were before, although still weaker compared to the Bones and the other stronger weapons. Basically, he is now the closest to reach Gaster's true magical Strength. He also feels his physicality increase, as he now feels more stronger and faster than ever in his life. While admittedly, Bete was a little bit faster than Sans in her true form.  It after killing her, his Physicality has increased to where he is now much more stronger and much more faster than Bete. But the one thing that he does not have, is Bete's Rhabdophobia. However, Sans does not seem to mind it. After all, he has the power to absorb the magic of anyone that he had killed, as long as he attacks and kills then first. So it doesn't matter anyway.

Sans than hears Gaster speak out.

"I'm so...tired."

Gaster than fainted, as he than landed into Papyrus' arms, who went there to make sure that Gaster is totally unharmed. After that, Papyrus was relieved, because Gaster is still alive.

"YOU DID IT GASTER..."

Sans nodded, as he spoke out.

"No...we did it."

Papyrus nodded, before he than realized something, as he spoke out to Sans.

"WAIT. SOMETHING DOESN'T FEEL RIGHT. I HAVE A BAD FEELING ABOUT IT. WE NEED TO GET US OUT OF HERE."

Sans nodded, as he and Papyrus began to go away. But as they did, Sans stopped, as he hears Bete's voice inside of him.

"Ahh...they killed me...Ironically that seems to be your biggest mistake yet...All this time I've been keeping it under control. But now nothing stands between IT...and you. And it won't stop until there's nothing left."

And Sans realizes what it is talking about, as he shouted to Papyrus.

"BRACE YOURSELF!!!"

Papyrus turned around, and an explosion of blackness and pink erupted from Bete's corpse, and covered the entire area that Sans and Papyrus are in, as the skeleton brothers were hit by the shockwave. Both Sans and Papyrus looked and saw a monstrous behemoth.

What was once Bete's corpse, is now a vessel for Hate, as the eyes of Hate stared at both Sans and Papyrus, it's monstrous form waved with the winds, and it than began rising up. Sans and Papyrus were horrified at the sight that is before their eyes, as they cannot believe what had just happened. But then, something caught Papyrus and Sans' eyes. They looked ken, and saw that Gaster is turning to dust, his body beginning to break apart, as Papyrus looked in horror at seeing his father being dead. But Sans realized something, as he than used his Hallucination ability, which countered Hate's, and it showed Gaster still alive. But Papyrus does not know that. Thinking quickly, Sans than raised his hands, and before Hate can strike at Papyrus, he summoned Bete's Scythe of Fear and blocked Hate's arm blade.

The moment that the 2 blades struck, Papyrus went out it of the Hallucination, as he than looked and saw Sans with the scythe, as Sand pushed Hate back a little bit, not very happy at what it tried to do to his younger brother. And when that happened, a voice spoke out.

"PAPYRUS, SANS!!!!"

The 2 skeletons turned around and saw Chara, and Asriel, as Papyrus spoke out.

"CHARA!!!!!"

Sans than looked at Chara and nodded, as he than spoke out.

"Nice to see you back to your old self, Asriel."

Asriel nodded, as he than looked at the scythe in his hand, and has a good guess as to why he has it. Sans and Chara looked at each other and nodded, as they know what to do next. Sans stepped forward, along with Chara, as Papyrus fled, as Chara spoke out.

"So be it."

Sans stepped forward, and he then spoke out to himself.

"Frisk, this is for you. You ready, Papyrus?"

Phantom Papyrus manifested next to Sans and nodded his head, as he than looks back at the Hate, as Sans spoke out.

"HATE, You have tormented this timeline for way to long. And now, here you are, taking away the happy ending that we had tried so hard to reach."

Chara than stepped forward, as Chara than spoke out to the HATE, that has taken over Bete Norie's corpse.

"You want to see HATE?"

Hate itself than readied itself, as though it accepts Chara's demands, with Sans stepped into forward, his scythe out, with both of Sans' eyes turning purple with red outlines and Chara's scleras turning black, as both than spoke out to it.

"Then let us show you our Animosity!"

???

Back in the location that held the boss of both Horror and Killer, he looked and see that Murder had grown even more powerful than before, as he now has a Scythe in his hands.

"Hmmm...interesting. This version of Murder, or should I say appropriately, Dust, from a fused version of 2 Alternate Timelinew, Dusttale and Glitchtale...he has become much more powerful than before, much more stronger than before, even more so when compared to his original self. He has killed Bete Noire, and he has now absorbed her magical power. And he is at LV 20, is more stronger than even Killer, my most useful servant, and if I were to believe, since he has the Hate inside of him, even though it is tamed, he likely has become more powerful than Chara, and is able to access File 0. Most importantly compared to those facts, he had the power of Determination and the magic of Fear, becoming the most special Monster in Glitchdust.

The figure intertwined his hands, his left blue eyes glowed, as he than spoke out.

"And yet...I don't doubt that he will refuse to come to me. So...I think I need a way for him to come to me, without him suspecting that it is me. I need to make this work on my favor. You can keep rejecting as many times as you might like to do, Dust. But in the end, you will come with me, one way, or another. I do not care how long it takes, I will make sure the you are enlisted into my services, no matter what it takes."
