**Insanity Sans** is a Sans made by Zero Danteero. In this AT Sans becomes a psychopath and murders everybody (or almost everybody) in the Underground, including his only brother, Papyrus.

## Backstory

His father (presumably Gaster) infects Sans with one of his experiments. This infection caused him to become a psychopath. The chemical (which is the previously mentioned experiment) removed crucial parts of his mind, namely **Happiness**, **Confusion**, **Common Sense**, and **Empathy**. Upon meeting Chara, Sans discovers the power of **RESET**, the ability to commit murder and get away with it. Upon knowing of this power, he uses it to Reset and kills everyone once the timeline reset.

As a psychopath, he enjoyed every moment of it. He has a rather sick personality and is portrayed as "unbeatable" due to his immense power.

## Profile

### Appearance

His appearance is similar to Undertale Sans's. His left eye twitches whenever he kills people. He has blood on his mouth, scattered throughout his teeth. Insanity Sans has an unusually large smile, so large in fact that it meets with his eye sockets. He has unusually small pupils that shake from time to time. He has wounds in some parts of his body, indicating the areas where his victims tried to attack, most notably his head. It has multiple cracks because it is the most practical area to strike.

### Personality

As the name implies, Sans is shown as very insane, incapable of feeling love and empathy towards others. He skewers monster's heads to show a sense of victory, but always carries Papyrus's head. Sans is so insane that he will attack anything, from noises to insects to movement and anything that can potentially hurt him. However, Sans will not do this while battling his victims, giving full concentration to them. Sans has a weak body, but endless energy.

Whenever he fights, he will be full of adrenaline that he will viciously shake and strike with insane power at random moments. He talks, but never to others. He repeats his victim's movements and makes random whispers to himself, further portraying his insanity.

## Abilities

### Spiked bones

Unlike other versions of Sans, his bones are sharp and can deal a large amount of damage. He holds them in his hands and stabs his victims with them. These can vary in size like normal bones.

### Hard hitting punches

He is able to punch very hard, harder than a normal human. He uses this, and the bones, more than his blasters and telekinesis, as he prefers hand-to-hand combat.

### Insanity Blaster

Like a normal gaster blaster, except it is cracked and blooded. He doesn't use this as much as its a bore for him.

### Shortcuts

Sans can travel or teleport anywhere instantly.

### Telekinesis

It's the same as the other versions, but he also doesn't use it that much. He prefers hand-to-hand combat.

## Trivia

* Faku's original Insanity Sans’ sprite was inspired by another one of Zero Danteero's Sanses, called Madness sans. Madness and insanity are technically different, but can be considered the same.
* People often mislabel Insanity Sans’ Alternate Timeline as an AU called ‘Insanitytale’. This is completely wrong.
	+ There is a different Au named Insanitytale, these aren't related at the slightest.

* There was drama surrounding Insanity Sans’ ownership around late 2020, as a YouTuber called FanOverDell had falsely claimed ‘official’ ownership of Insanity Sans and rebranded his entire story and relabeled his AT as an AU called Dirtytale. this name was made because sans here was the ‘Dirty Brother Killer’.
* Insanity Sans’ Megalovainia remix was posted without any information on the sans in the thumbnail. It was revealed later that Zero Danteero had a story that described him, incase it was ever required.
* The Papyrus head is still alive, which is why it has not dusted.
* Mirrored Insanity is not canon to Insanity Sans.
* Insanity Sans’ HP is presumably less than 20, as in the VS. Frisk short music video, Frisk notes that ‘One hit’ then sans will be dust. Considering that frisk has stumbled into an empty underground, they still probably have the stick as their weapon.
* He's not Canon to Team Void/Team Hope Universe, if he was, he'd be recruited by Dust after Mirrored Insanity, instead of dusting Insanity, he recruits him.
