Inc.

Appearance
Ink is a skeletal monster, slightly shorter than the original Sans. Characteristic details of the character:

Clothing: overalls tucked into pants, white T-shirt, gloves. The light green color of the gloves alludes to graphics tablet gloves, hinting at his connection to creativity.
Accessories: A scarf that Ink uses to write notes due to his poor memory.
Brush: His main tool, with which he creates and fights.
Eyes: Pupils constantly change shape and color, but are never white.
Lack of shoes: emphasizes his carefree and active nature.
Ink details: sometimes ink literally "pours" out of it - especially when emotions are strong.
The color scheme is bright and “artistic”: lots of yellow, green, and contrasting accents.

Character and features
Mischievous and ironic: he loves to joke, can be harsh at times, but at the same time sincerely supports creators.
Forgetful: Because he has "torn" his soul, he has trouble retaining memories, so he constantly makes notes.
He is afraid of emptiness and whiteness: huge empty spaces and the absence of forms are unbearable for him – this literally frightens him as an artist.
Supports the arts: he patronizes artists and authors, wants them to continue creating, and protects the universes themselves as manifestations of creativity.
A peculiar moral: he does not judge by conventional standards, but rather by how “alive” and productive the universe is.
Capabilities
Ink Manipulation: Creates objects, barriers, clones, uses ink as portals.
Teleportation: Can move through liquids or "cut" space with scissors.
Creating and Animating Objects: Using his brush, he can materialize things and give them properties, but he cannot create full-fledged characters.
Script Reading: Able to see AU code fragments and predict
