Error

Character:
Rough, hot-tempered, selfish, dominant, sarcastic, tough, aloof, calm, very rarely can be gentle and more friendly.

Blue Threads (a concentrated version of telekinesis magic):
Error can pull them from his eyes and hands. Using the threads, he can capture souls, move them, and destroy them. If the threads penetrate the victim's body, Error can transfer his soul into theirs, controlling them and leaving them helpless.

Gaster Blasters (Error Blaster):
Black skull-shaped devices that fire powerful lasers. They're larger, faster, and more powerful than the classic Sans's.

Teleportation:
Capable of opening portals to other universes (one-way and two-way), as well as showing the past of himself or other characters.

Manipulation of higher dimensions and the void (controls the Anti-Void - the realm of nothingness located beyond reality).

Error is a man. (His name comes from the word "error.")

Appearance:
Short black-blue hair, darkish skin, red-yellow and black pupils, blue circles under his eyes. Wears glasses due to poor eyesight.

Cloth:
Most often he wears a black sweatshirt with a blue hood, a red T-shirt, black sweatpants with one blue stripe on each leg, black slippers, and blue glasses.

Chocolate (he loves it), his cat, knitting dolls, watching other ABs, relaxing, destroying ABs (but he rarely does this anymore). Dominance and being in charge.

When he is disturbed, by noise, introverts and similar people, when he is given orders, too much touching (I know that according to canon he hates it).
