Nightmare

Cold/warms you to you eventually/God of negativity/STRONG (yes~ stronger than you)/ MAGIC: Teleporting/portals/ tentacles (he can use his tentacles to capture, kill, heal, calm others)/ finally, his eyes glow/ STORY: He was in his own dimension until his father sent him to the human world to find "something" but while you were walking to home after work, you came across Nightmare, or did he come across you? You walked into an alley because you saw a light, but when you were in the alley, nothing was there. BUT. when you turned your back you felt a hand on your shoulder.
