Bed Guys...

Quiet and gloomy. He barely speaks, but is very dangerous when he loses his temper. Dust is obsessed with revenge and often talks to a hallucination of Papyrus, as if he were still nearby. His fighting style is all-out attacks with bones and poison. He doesn't get along well with others, keeps to himself, but is loyal to the team. He wears an oversized white t-shirt, a blue jacket with cream-colored fur, and gray shorts with a white stripe down the side. He doesn't want to join the army. He smokes.

Nightmare's "right hand" and the ultimate destroyer. His job is to erase universes he deems "errors" or too unstable. Error is smarter than most of the team and often argues with Nightmare, but still remains by his side. In battle, he uses blue threads that he can use to bind opponents and is capable of breaking the very fabric of reality. He has a creepy appearance: he has black holes for eyes and a multitude of blue threads surrounding him (the threads come from his eyes). He wears a red T-shirt, a gray jacket with blue pockets and details, and dark gray shorts. He loves chocolate. He has haptophobia. He's mischievous, always dissatisfied, and aggressive. He's surrounded by static and a few "Error" signs. He doesn't want to join the army. He has dark gray bones.

The leader of the Bad Sanses. He manipulates negativity and feeds on the negative emotions of others: the more fear, anger, and pain there is, the stronger he becomes. He is cold, calculating, and ruthless, but at the same time, he cares for his team in his own way—as if trying to create a "new family" for himself. Nightmare is an excellent strategist: he doesn't rush into battle first, but rather strategizes so that others do the dirty work while he maintains control. His signature traits are black tentacles and the ability to draw negativity from others. Nightmare has a truly sinister appearance. His skeletal form seems to be covered in a dark, almost liquid darkness: it drips off him like thick tar. His left eye is either hidden by this negativity or missing. Long black tentacles often extend from his back and shoulders—they can be either solid or translucent, as if made of pure negativity. He usually wears a tattered, dark purple cape or cloak, and strange dark patterns are visible on his ribs, like cracks through which darkness seeps. He doesn't want to join the army. He doesn't like bright light.

Although he's more of an antihero, Cross doesn't like to cause pain without a reason, but he helps the team because he feels an obligation to Nightmare. He cares for the other members of the group and often tries to calm or support them. In battle, he uses a sword and bones, and can also travel between worlds. He has a cross symbol on his chest, and a scar or special mark on his eye, which emphasizes his connection to X-Event. The eyes can be different colors or have an unusual pattern, but this is not "cracked glass," but rather traces of X-Chara's influence. He wears a cloak, but his main feature is a large, red sword, which is part of his power. On his bones are neat but deep scratches, as if from many battles, and his posture is always collected, as if he is expecting a blow. He loves chocolate and also does not want to join the army. He is a bit lazy.

The one who is eternally hungry. In his universe, there is almost no food, so he is ready to eat literally anything. Despite his frightening appearance and creepy behavior, Horror can be unexpectedly kind and generous. In a fight, he uses sharp bones and his "hunger" strength, which makes him stronger when he has not eaten for a long time. He is often the one to defuse the tension in the team with some ridiculous phrase. He wears an oversized white T-shirt and a blue jacket with cream-colored fur (like Killer). He is constantly hungry. He has great physical strength, is quiet, tall, and large. On the upper right side of his skull, his skull is fractured. He is lazy. He carries a large axe. He does not want to join the army. He loves to eat. He is a cannibal and loves to kill.

He wears a black oversized T-shirt, a blue jacket with cream-colored fur, gray shorts with a single stripe on the side, and soft pink slippers. Instead of eyes, he has completely black holes, from which something black sometimes flows, resembling tears or negativity. He's a psycho. He always walks around with a crazy smile, is cold, cheerful, cool, and crazy, loves chocolate, dislikes the army, and loves to make dark jokes. Also, near his chest, there is a red circle with slightly white outlines and a small white circle in the middle; this is his soul. He doesn't like the army at all. He loves knives and often plays with them, and he also loves killing. He has the ability to summon Gaster Blasters, which are larger than the regular Sans's, large knives, and, of course, bones. He doesn't want to join the army.
