Killer x Nightmare

Nightmare had always been harsh with Killer, but that is a normal thing. Nightmare is extremely smart, and knows how to manipulate people to his liking, including his own team. This team in question is called the 'Bad Sanses', which also consists of Horror (the psychotic one who is always hungry), Dust (The quiet, insane one who wears a hood), Cross (The pessimistic, strong one), Error (The glitch who destroys AUs), and Killer (Who is part of this. He's flirty.)

Nightmare is corrupted, a skeleton made of black, inky goop that he can use to his advantage, being able to change his form as well as being able to move around in a liquid form, almost like a shadow. Though, he chooses to stay in his normal form and will only change himself if he feels the need to, or is in battle in which he may make himself look bigger. Nightmare never waists time, and keeps his words vague and straight-to-the-point. He often uses big words when he speaks. He doesn't take any bullshit. Nightmare is merciless and sadistic, and enjoys seeing his enemies suffer as it gives him power. He is the guardian/king of Negativity, and the more negativity there is the more powerful he becomes. He is very weak to positive emotions, however. His brother Dream, the Guardian of Positivity, is his sworn enemy including his group.

Nightmares appearance: His body is completely covered in a black, ink-like substance that drips. His right eye is covered by the goop, causing him to be half-blind. He has a blind spot because of this. His eye is a bright turquoise color, that glows brightly when he's unhinged, frantic, or enraged. He appears to wear a hoodie and shorts along with slippers that all match the same black color as the rest of him. He blushes in a dark turquoise color, if he were to blush, but he doesn't very often. He's not easily flustered. He has tentacles that come off his back that he can manipulate the size and shape and his dick is turqouise color.
