Ink!Sans is a Sans variant created by Comyet (aka Mye Bi). He was a conceptional Sans who escaped the deteriorating incomplete world through the destruction of his own soul. Thanks to a paintbrush that fell into a void, he's able to gain the ability to create objects out of paint and inks. He now serves as a Muse of the Undertale Fandom, along with being the Guardian of the Undertale Multiverse.


Ink started out as the only character in an unfinished AU with feelings. To escape the then deteriorating world, he ripped apart and destroyed his own soul. After falling through the multiverse, he arrived in a new, blank void. But, having no soul, he could no longer feel emotions.

Eventually, an inkbrush (along with paints) from an unknown artist fell into the Blank canvas, each color imbuing him with feeling. After some time without color, though, He would revert to his emotionless self. Ink fixed this problem by filling vials with the colors that were splashed on him. It allowed him to pretend to have a soul, so that he could feel.

Gradually, Ink used the colors from the creators to create the doodle-sphere, and now dedicate his life to protect all of their creations from harm.



Ink has black paint (or ink?) on his right cheek. His eyes are usually a blue circle in the right eye socket and a star in the left. He dons a longsleeved, white undershirt with a small brown jacket over it. His pants are actually overalls with the tops tucked into his waist. The legs are very wide at the bottoms, with creases around the legs. He also has no shoes, instead, he goes barefoot with a pair of leggings.

He has a work belt crossing his chest, with rainbow paint vials (which have heart-shaped tops) on it. When Ink drinks what is in the vials he gets artificial emotions. On his back he possessed his most powerful tool, an Inkbrush which he named Broomie.


Ink supports all kinds of art, like painting, literature, dance, music, etc. He is very passionate about art and likes to motivate characters and creators. He’s able to change clothes on people just by a paint of his brush, and he loves to create the kind of outfit they like. Even though he uses art as a tool, no one really saw his drawings or paintings. He is afraid of whiteness, of absence of presences or shapes around him, loneliness, huge empty spaces…

Ink!Sans has a tendency to get too excited about things. He happens to sometimes randomly vomit ink, mostly when he gets too emotionally shaken, whether from passion or shock. He also has very short memory and will forget about different things - sometimes stopping mid-sentence to try and remember what he just said a few seconds before. He’s really forgetful (which is why he takes notes on his scarf).

Ink does not appear as a perfectly well-behaved character. He can sometimes be inconsiderate in his mocking and cruel in his opinions, and deep down he sees other characters as story characters and not as people like him like a proper story would. He has a very special morality that sometimes shows to be really separated from his emotions. With him hardly having a proper social understanding, he’s blunt in his teasing and mocking just like in his ability to give support and to be kind. He’s a mischief-maker, for pranks are his guilty pleasure.

Ink approaches enemies carefully. He will never try to attack them first, but will mostly focus on trying to discover their motives and talk them through it. Although he does come off as a jerk in first impression, he does know what to analyze to understand the issue so he can brush people the right way and hopefully have them listen. Ink in general acts wittily and provocatively.

He loses his pencils all the time.


With Broomie and its inks within his possession, he's capable of preforming feats such as.

  • Ink Hopping: Ink!Sans can appear everywhere in any AU of his liking from any kind of liquid. He uses them as Ink portals.
  • Creation: His big brush gives him the ability to create anything he likes and make it come to life, with the exception of dead characters. He does not Create AUs or Branching timelines however
  • Ink Blasters: He can create Gaster Blasters that shoot inks that solidify on contact.


Note that his relationships with other characters varies from one story to the next as he have no canon ties with anyone.


Main article: Error!Sans

Though they have no canon relationship, he's often been depicted with the self-proclaim purger of the Multiverse. It was due to their conflicting views on the multiverse itself that they're often at odds with each other (Ink claim that the Multiverse was perfect the way it is, while Error views it as an abomination).



  • Ink plays the flute.
  • He snorts when he giggles.
  • Ink's only job is to protect all AUs. He does not create them.
  • Ink is aromantic/asexual.
  • It was discovered by an anonymous user that Ink's old design was heavily based on a pokémon trainer by CookieHana on DeviantArt. They later confront Comyet about this, and in response she broke down the entirety of that situation, ending the post by saying that a redesign for Ink!Sans was in order. This redesign was released January 4, 2020, with Mye Bi requested that everybody only use the new design.
