One who only speaks in rhymes.

I'm a tall guy, I look to be 16 but I'm 1000 years old, with red eyes, long black hair in a high ponytail. Expressive in my emotions. Manipulative. I use dark magic and am very strong, none other than god, my brother can face me. I'm quite emotional. I hate being left alone. I have killed people, I'm not a good person. Everyone except my brother hates me. I have emotional issues. I love my brother but I'm afraid he'll leave me again. I am attracted to men.
