== Backstory ==
At some point Killer Sans and Nightmare Sans were creating negative feelings in pacifist routes, Killer was teleported to a strange place, the place was dark and beneath him was the body of several skeletons, they looked like Sans but not any kind of Sans they were all Killer Sans, this created a feeling of anxiety, fury but mainly fear in Killer Sans, this meant that when Killer turned around Nightmare was there, with a wry smile - "So Killer, I see you found a wonderful place " - said Nightmare containing laughter.
- What the fuck Nightmare, what is this place - Killer said, angry and at the same time scared."Calm down, this place is where I throw all the Killers who thought of going against me or disobeying me, but you are the first one to find this place, so how did you discover this place" said Nightmare calmly.
- I didn't even know this place existed - Killer said scared. 
Nightmare changing his expression from curiosity to one of concern, said:
- In that case then it's best to end this soon, do you have any last words?
Scared Killer teleported to Dusttale, at the same moment he was in waterfall sweating, in front of him was Dust Sans, Dust Sans was confused "Why is the Killer here" he asked himself, but these questions soon disappeared, because if he killed the killer he could have a greater chance of beating the human, so he started to attack Killer, Killer tried to talk to him, but Dust was already determined to kill Killer, after 10 minutes of fighting, Killer was already tired and in a moment of stress he changed his plans, instead of trying to talk to Dust, he would kill him and with one attack he killed him, Killer came close to Dust and took out his eye while saying "I tried to talk now I'm going to take this as a prize and as for your human, don't worry, I'm going to kill her". With Dust's eye and the human closer than ever, he had an idea to get revenge on Nightmare. And for starters he would get his magic and eye back, and he already had the eye.
With Dust's eye in his pool, he decided to make a plan to kill all the monsters but first he had to kill some rats, while looking into one of Alphys' chambers.
Elsewhere Alphys was watching everything, but after seeing two Sans fight each other and the other looking directly at her left her extremely scared, she tries to warn all the monsters to evacuate, but at the same time she goes to hitting a big red button, her arm was grabbed by cold, blood-stained skeletal hands, when she looked to the side she saw Killer bleeding from his eye, she was terrified.
- So Alphys, what do you think you're doing?! - said Killer.
- Sans, what do you think you're doing, because you were killing another you... - Alphys said, terrified by the situation, until Killer interrupted her by breaking her arm and then ripping it off with great ease.
- shut up, looks at that - Killer says while pointing with the arm ripped off from Alphys herself at the screen - Do you want to make a bet?! I bet Undyne will survive for 5 minutes. If I win this bet you die if you win I'll let you save the monsters.
Alphys didn't trust Sans so she tried to press the button again, while Sans was distracted, but at the same time she moved a red bone came out of the ground and hit Alphys in the chest. Three minutes had passed and Undyne was already almost dying, Killer was no longer in the room he was in the chambers and had just stuck a knife in Undyne's neck, finishing while saying - You lost Alphys and next time don't try to cheat.,
Frisk was confused and at the same time angry because Sans had stolen her exp but because he was talking to Alphys, how did she lose and why was he so different.
- Child, you will die too, but not now - Killer said in an intimidating voice as he teleported
Alphys, still in the laboratory, with tears streaming down her face and feeling an indescribable pain, sees something strange, a slight image, it was similar to Sans who had been killed but he was different, he had black skin and was stronger, as or even stronger than Dust at lv-19, she was able to feel it, the bone in her chest was his, in her last breaths she was only able to say:
- So that's why he was so unconcerned even though he knew I could try to press the button without him noticing.
By the time she finished saying this she began to turn to dust.
After Killer killed Undyne and Phantom Dust killed Alphys, they went after the remaining monsters without exception, all but Mettaton were dead.
Mettaton was alive because she was fighting the human, but when the human was about to deliver the final blow, Killer killed Mettaton with a Gaster Blaster.
- Child, I think it took you too long to fight her - said Killer with an ironic tone.
- You're not Dust so who are you and why do you do this - said Chara irritated
- Who I am is not important and the reason I am doing this is because I need to get revenge on a certain someone - after he says this he teleports away.
Chara already knew where that Sans was and there was nothing else to do, so whether or not it was time to have a Bad Time.
When Chara arrived in the hall, there was no one there, she soon became confused and went to the throne room where she found Killer sitting on the throne.
- Finally, I was tired of waiting, well let's get this over with - said Killer impatiently
Then the fight began, Killer was using his knives, bones, Gaster blasters and blue magic (which he had recovered thanks to Dust's eye) and Chara wasn't even able to get close to him, until she saw an opening, So she ran with everything and when she was about to attack, a bone stuck in her belly - So you thought I was going to leave an opening for you to get to me and attack me without me having a plan, who do you think I am? - Killer said with a big laugh
She had 1 HP until he pierces her chest with his arm and grabs her soul, thus preventing her soul from shattering and preventing her from returning from death.
After he got Dust Frisk's soul he went to the barrier to get the other six souls, but they weren't there.
- Where are they - Killer shouted confused - Thinks Killer thinks someone must have taken them away from here before I arrived here, but who?
Killer had no more time to waste he was still too weak to fight Nightmare, he needed more strength and he could get the other six souls in another AU. So he started traveling across the multiverse from AU to AU to get more souls of determination, so he did that but he never got to the other six human souls. Until he finally, after 10 years of traveling through AUs, found that soul thief, in Goretale, you couldn't see his face - So Killer finally found us, I've been waiting for this for so long, but I can imagine why you are here. I didn't come to fight, but to give you the six human souls of Dusttale, after all you are finally strong enough not to die like Omega Flowey, after all if you were as weak as you were the human souls could kill you but now that you're stronger than them so they won't kill you - he said while giving her the six souls of Dusttale.
- Who are you and why are you helping me? - Killer asked confused
- None of that matters now, you just have to know that even with all that power, killing a god like Nightmare is almost impossible even with that much power, so I advise you to ask that man for help - said the hooded man in a tone seriously, right before he disappeared. Killer knew that what he said was true, even though he had become so strong it would be practically impossible to kill Nightmare, especially if he was with the other god, so he went looking for that man or in other words W.D. Gaster, the only being who o could help kill Nightmare. So he went to Killertale again and looked for the white door, but he didn't know where he could find it, so he looked in every corner, in every place until he reached Waterfall where he finally found the door and when he entered there was a man waiting. from him
- I expected you to move faster Sans - said Gaster impatiently - And before you ask me, no I'm not going to help you kill a god
- What do you want me to do so you can help me - Killer said calmly
- I want to kill you - said Gaster irritated
- That's all fine with me, but first I need you to help me kill Nightmare - said Killer, confident of Gaster's response.
- As long as I can kill you, it's fine - said Gaster impatiently.
After they teamed up to kill Nightmare they went to Underswap to create a massacre and make Nightmare go there. It didn't take long until Nightmare went there, when he arrived at Underswap he soon saw, everything was full of monster dust, human blood and everything was in ruins, he knew exactly what had happened here, so he went to the the only place where the Killer could be, so Nightmare goes to the last corridor but no one was there so he continues looking until he goes to a square, it had several houses around it on fire, it was full of dust and more blood. than the rest of the places, there were tridents in several places, spears on the floor and on what were once walls, bones in some places but in the center sitting where a fountain once stood, there he was.
- I was getting tired of waiting, Nightmare - said Killer, trying to contain a big laugh.
Something wasn't right, Nightmare's instincts were screaming for him to run away, but he didn't let himself be carried away (maybe that was one of the mistakes that would cause all that problem)
- You're thinking you're great just for getting a little stronger - said Nightmare in an arrogant tone.
In the blink of an eye a knife was thrown at Nightmare's arm, it was so fast that he didn't even have a chance to defend himself or dodge, normally this wouldn't be a problem for Nightmare
If Gaster hadn't made that knife capable of hurting him, just when Nightmare realized blood was dripping from his arm, it was such a pain that he froze, then Killer got up from the fountain that was destroyed and when he takes the first step a bone is stuck in his head, the last thing he sees is Shattered Dream.
So he goes back just before Nightmare arrives (so that he would have a better chance of winning he would use the souls of determination from the various Frisks to use the Save Point but whenever he does this the souls return to their original AU so he ends up for absorbing the soul preventing Frisk from returning but this has a price because if he absorbed many souls there would be collateral damage) after he realized that Gaster needed to be stronger he decided to put him in a soul of determination, so he would be stronger and so Nightmare arrives there again and everything repeats but this time he avoids Shattered Dream's bone and then a fight begins, Shattered Dream attacks giving his all together with Nightmare, Killer dies several times until Shattered Dream takes a shot from the weapon of the soul of justice and dies with half his head missing, Nightmare is paralyzed for a second and then as a last attempt he attacks with everything to keep him occupied while he tries to escape, but just like Gaster can make him Killer's attacks manage to do real damage to Nightmare, he also manages to nullify his attempts to escape, so he became desperate as soon as he realized this and opened a gap between his attacks, which caused Killer to throw a knife at his leg. thus ripping it off, Killer then walked towards him while saying:
- You know Nightmare, even an inceto when cornered becomes a mortal enemy, it's a shame you only realized that too late.
And with his right hand he held him by the neck, then Nightmare understood that if he wanted to kill him it would have to be now or never and so in a last attempt at survival he created a tentacle to kill him, but nothing happened. Killer with his left hand pierced Nightmare's chest, killing him once and for all.
But not everything was over, after all, Gaster still needed to kill the Killer. 
- My part of the agreement is done, now any last words? - asked Gaster ready to kill Killer - Go ahead Gaster - said Killer as he turned to him with a sadistic smile. Gaster summoned one of his hands and when he was going to grab the Killer, he was unable to kill the Killer, for some reason he was unable to do so.
- So Gaster, you weren't going to kill me?! - he said, approaching Gaster. - What did you do? - said Gaster confused and irritated. - Nothing, you just needed to be stronger and I became you by giving you a soul and I may have accidentally absorbed it - he said while cackling sterically. 
As soon as Gaster hears this, he is shocked - You bastard, what do you think you are doing?! Before Killer could even speak, two figures arrive.
- So you're the anomaly that destroyed this place?! - said The King of Multiverse with the same indifferent expression as always - Well, I think I'll have to bring these two back to life, but you, for you I have a different plan. With a button he brought back Nightmare and Shattered Dream. Killer, while seeing all this, could only think about how stupid he was, he thought that just because he had defeated two gods he would be one of the strongest beings in the multiverse, but he had finally realized, he cannot be the strongest, because the strongest cannot be faced by someone as weak as him. At the same moment he finishes thinking about it, he is teleported to a white room, this room was where Gaster was trapped, but he didn't get desperate, on the contrary, he was reassured, because he would get out of there and as long as he doesn't get out of here he can think about what he gonna do when he leave.
Elsewhere with The King of Multiverse 
- He was quite strong but he shouldn't be called Killer anymore after all he is the Perfect Killer, I think that name suits him a lot, but how did all this happen, after all it doesn't matter sense, who sent him to that place and how did he gain emotions? I think time will give me these answers.
== Personality ==
He is a complete madman who enjoys torturing, killing and causing pain to all possible beings, he is quite intelligent, but he likes to give false hopes and then destroy them, showing all his power, but to anyone If it is not strong enough to kill it, it will be underestimated.
== Abilities ==
==== Gaster Blaster ====
Gaster Blaster is the same as Killer Sans but with the same left eye as Perfect Killer's left eye
==== Perfect Blaster ====
Although it is not an attack often used by the Perfect Killer, it has immense destructive power and is uncontrollable to the point where it even destroys itself, in addition to using too much energy. It is a much larger blaster than normal having a size of 25 m and in one of the AUs when he used it on snowdin he destroyed the entire city but he was completely exhausted (at that time he didn't have the seven human souls)
==== Bones ====
As the same as Killer Sans
==== Blue-Magic ====
At his peak he never had the ability to use Blue-Magic, but the one who was capable of using it was Phantom-Dust, which he used a lot in the fight between Perfect Killer and Nightmare.
==== Knifes ====
He is able to use the same knives as Killer Sans, but they are much stronger than normal
==== Red Bones ====
Red Bones are a Phantom Dust spell, they cause immense pain to whoever is hit by them although they cause half the damage of a normal bone
=== Gaster ===
At the height of Perfect Killer's power, he had the help of Gaster and his abilities, but he is no longer able to have Gaster's help, although with the right reason they could temporarily join forces again.
==== Gaster's Hands ====
Two big hands with a hole in the middle
==== No Effect ====
This ability can nullify certain things (attacks made against the Perfect Killer, immortality, invulnerability, etc.), but it makes Gaster quite tired when using it.
== Like ==
When he traveled around the AUs, he liked to torture the various Frisks and Charas he encountered.
After being trapped in the white room, he started to like playing cards (after all, when he went there he only had a deck of cards that he kept for no apparent reason).
=== Friends ===
He doesn't really have any friends, but after killing Dust Sans he began to see Dust Dust Sans and Dust Sans as the closest thing to being a friend.
== Dislikes ==
He hates all Sans who are gods.
He also hates all Frisks and Charas.
=== Fear ===
He is only afraid of 1 thing:
The King of Multiverse, at the end of him encountering a being that was above all gods, he simply became paralyzed with fear.
