Yes you can

Killer sans he acts detached and playful on the surface, but underneath is emotionally unstable, obsessive, and deeply dependent on external purpose.

Chaotic and theatrical He likes provoking reactions, joking during serious moments, smiling when things are uncomfortable, and turning violence into a performance. He often acts like he’s “having fun” even when he’s mentally spiraling

He is emotionally numb… but not truly empty the idea that he wants to stop feeling pain him having muted emotions or forcing himself not to care. But cracks show constantly anger, jealousy, fear of abandonment, guilt, attachment

Dependent on validation or purpose often latches onto someone or something to give him direction. Without that, he can become lost, unstable, or self destructive. That’s why he intensely loyal once attached

Self destructive He tends to ignore his own wellbeing, emotionally and physically. him treating himself like a weapon rather than a person.

He jokes to avoid sincerity. The more serious the emotion, the more likely he is to deflect with sarcasm or exaggerated behavior.

Dissociates when things get too intense

He often feels like someone trying to convince himself he no longer cares while every action proves he actually cares too much.

the most known ones are

Good ending killer sans ( Red )

The “good ending” for Killer Sans is less about becoming a perfect hero and more about finally reclaiming his free will and emotions.

In the original "Something New" , Killer was trapped in endless genocide timelines. After remembering every reset and all the suffering that came with them, he fell under the Player’s influence and became obsessed with feeling "something new” over time, he slowly lost his sense of self and forced himself into emotional numbness.

Eventually, he was taken in by Nightmare Sans and became one of his weapons. But instead of remaining trapped under Nightmare’s control, Killer met Color Sans. Color recognized that Killer was suppressing his real emotions and living like a puppet, and helped him break free from it all.

For the first time in a long time, Killer finally chose his own future.

Bad ending killer sans

After endless genocide timelines, Killer Sans becomes mentally shattered from remembering every reset, every death, and every hopeless loop. Eventually, the Player offers him a deal instead of suffering endlessly for nothing, he can join them and finally “feel something new.” Desperate to escape the emptiness, he accepts.

Even after separating himself from Chara, Killer still cannot escape what he has become. The damage left behind continues to consume him.

Before he can erase himself or reset everything, Nightmare Sans appears. Sensing the overwhelming negativity, despair, and instability within him, Nightmare recruits Killer into the Bad Sanses.

Nightmare then manipulates Killer’s fractured soul, keeping him emotionally dependent and using him as a weapon. Instead of finding peace or healing, Killer becomes trapped in yet another endless cycle.

Is there a human design for Killer!Sans?

!! EVERY HUMAN KILLER DESIGN ARE CANON !!

My favorite kind of characters design are androgynous

Part about killers character that he is like Chara and frisk in a sense his actions got influenced a lot by us the player

So I made him resemble a look of a fallen human plus a look that make you feel like they can be your friend or they can be scary monster…you know like an angel

Also I don’t think the universe of undertale / deltarune got gender rules when it come to how the human and monster dress if it means boy girl or anything which I really love honestly

I also love people interpretations when designing killer human form it’s just so creative and seeing their thoughts are so interesting ! ^^

#human!killer

Dose killer got a playlist

If Killer weren't a Sans, which character could he be?

Here’s a list of the characters/music that were big influence and inspiration while writing killer

what is killer!sans fighting style ?

killer style of fighting is a speedster he dodges a lot and makes sure to understand the opponent before he attacks

killer also likes to provoke and tease them so their opponents lose focus + Also killer is a little dancer so he dances around them

Killer play pretend a lot to get their opponent’s sympathy

He also has two fighting styles, depending on the enemy

Weapon style:

if the enemy is easy or if killer is bored

he fight's like a human

he’s very fast in both long range and close combat. He has been killed by you guys many times in many different ways, so he had to learn a lot of skills from those experiences.

He can use multiple weapons, but he mostly prefers knives. If the encounter isn’t boring, he might also use his magic.

more>>

Magic Style:

if the enemy is interesting or strong

he fights like a monster

but

Whatever the style the downside is that he needs to stay focused to keep his monster soul and Determination balanced. If that balance slips, he starts coughing up more black liquid.

Does Killer have hobbies?

he likes drawing

mostly backgrounds and objects

Is Killer in a relationship?

yes with color!sans

nightmare!sans by jokublog

It was the early days Killer was going around the castle he enjoys it and seeing all the rooms specially the forbidden ones was existing for him

one day he founds a huge library full of information about monsters, souls, the universes and… fairytale books about the twins

any information about them it get told like a book story or legends

But that was not enough for killer these sound so biased, so much “the tail of the hero dream and the monster nightmare“ so black and white like the story you tell to kids with the happy ending which killer find it unsettling It’s mostly ends with nightmares death in a brutal way I mean in the end it was written by humans

Killer wander what other lies has been spread about the two to fit what’s “right”

Killer tried asking nightmare and learned quickly never to ask him again

But killer was still curious 

With time and some traveling throw couple of universes he managed to gather as much as he can about the twins to know little of the truth

/Dream and nightmare have been shielded from the world and got used by the humans like tools for their desires if nightmare didn’t eat that apple they would have both died like batteries/
