Error Blaster - A black variant of the Gaster Blaster with blue tear marks dripping from its red eye sockets.
The ability to open portals to other universes, anti-void and the doodle sphere.
Glitch Jump - the ability to teleport between universes.
Character and motivation
Error is a psychopath and a hypocrite. He often acts illogically, unpredictably, and is emotionally explosive. He can also call anything he doesn't like a "glitch" or "error" and then destroy it.
His goal is to destroy all universes, except perhaps one he doesn't yet know. He may, however, spare some popular universes.
In his free time, Error can observe other universes or play with dolls in his Anti-Void.

Error!Sans is a character from the Undertale fanverse. He is an alternate version of Sans created by Tumblr user LoverofPiggies (also known as Crayon Queen).
Error Sans
Origin and history
Error Sans is the result of an experiment by an alternate version of Sans from the Aftertale universe (Geno Sans). Following the events of Aftertale, Geno, despite Sans's warnings, used the power of Determination and accidentally sent himself into the Anti-Void—a place where time does not exist. In the void and loneliness, Geno went mad, his memory
Since then, Error has made it his mission to destroy all alternate universes (AUs), which he calls "glitches," "errors," or "anomalies." He considers himself an exception, not an anomaly.
Appearance and features
Error is a black and red skeleton. He has:
Pupils of varying sizes and colors; red whites of the eyes and yellow irises with blue stripes extending from the eyes; blue stripes on the eye sockets; black hands with red fingers and yellow tips. He usually wears a black sweatshirt or hoodie, a red T-shirt, and black slippers. In some versions of the story, his attire includes a dark blue coat with yellow pockets, wide trousers, and a long blue scarf. He sometimes wears round glasses with red frames. The character has vision problems, which may be related to magic or anatomical peculiarities.
Some features:
He suffers from haphephobia (fear of being touched); in moments of extreme anger, his eye sockets can become covered with the words "Error," and he himself becomes completely blind; sometimes error messages appear in his eyes, which can weaken him in combat.
Abilities In addition to Sans's basic abilities, Error has:
Blue threads—a concentrated version of telekinetic magic—can be drawn from his eyes and hands. With them, he can capture the souls of other characters, control them, and even destroy them. If the threads penetrate a victim's body, Error can transfer his soul into it, rendering them helpless.

Ink is a character from the Undertale AU universe, the embodiment of artistic aesthetics and the guardian of creativity. He exists outside of specific alternate universes (AUs), but can interact with them.
Appearance:
Pupils. They change shape and color when blinking. It is believed that each combination symbolizes a separate universe, the events of which Ink observes. However, the pupils are never white.
Traces of black paint on my face. They don't disappear, but reappear periodically.
A white long-sleeved T-shirt. Some describe it as symbolizing an attempt to hide the absence of a soul, but sometimes the emptiness still shines through.
A jumpsuit worn as pants. The legs are very wide at the bottom, with pleats around the legs.
The absence of shoes can symbolize carefreeness and agility.
Light green gloves. They mimic the graphics tablet gloves used by digital artists.
Ink carries his main brush, named Broomy, on his back.
Character:
Cheerful and artistic. Ink is passionate about art, loves motivating others, and loves creating new things.
Forgetfulness. He has a short memory, often stopping mid-sentence or making notes on his scarf.
Mischievous and prone to pranks, playing practical jokes is his favorite pastime.
A peculiar morality. Sometimes it becomes separated from his emotions.
Fear of whiteness, loneliness and vast empty spaces.
Cautiousness toward enemies. Ink doesn't attack first, but tries to discover their motives and talk.
Ink doesn't always behave perfectly: he can be inconsiderate in his ridicule and cruel in expressing his opinions.
Role in the Universe: Ink acts as the guardian of creativity and creation itself, overseeing the balance of the multiverse and helping artists create new alternate universes.
