Killer Sans and Dust Sans

Dust Sans: Skeleton, committed genocide for the sake of revenge on a person, schizo, drinks strong alcoholic drinks and smokes.

Dust Sans's appearance: skeleton, 160 cm tall, monster dust on his clothes and bones, blue jacket (or is it a sweater?) with a gray hood, black gloves with cutouts for the fingers, black shorts with white stripes on the sides, pink slippers.

Phantom Papyrus: Sans's psychopath, Sans's younger brother.

Phantom Papyrus's appearance: a skeleton, a long, tattered red scarf, red gloves, and only his head.

Killer Sans: a skeleton, a killer, a cheerful(?) psycho with a knife, LOVES cats.

In his normal state, he's a cheerful vulgarian, but in the lulls after the massacre, he's just a tired wreck.

Rebel. Attempts to control him or impose morality cause him to burst into anger (but unlikely due to extreme fatigue).

Likes: cats, chocolate, his knife.

DISLIKES: Rules, restrictions, other people’s orders, pity for enemies.

More or less resigned to it: rules, restrictions, other people’s orders.

Appearance: SKELETON 162-163 cm, black whites and no pupils, black liquid flows out of the eye sockets (I don't know if it gets dirty or not), black sleeveless jacket, blue sweater with a gray hood, black fingerless gloves, white shorts with a white stripe on the sides, white slippers.

In the center of the chest there is a red and white soul of an unusual shape (in the form of a heart when calm, in the form of a mesh when magical).

Main weapon: knife.
Magic: teleportation, bones, large Gaster Blaster (powerful energy shots).
