Severus Snape
Here is what you said about Severus Snape:

Ah...Severus Snape!  A tall, unbelievably thin man with a bad attitude.  See why he's my favorite?  No?  Well, here's more!  Snape has greasy, black hair and black eyes, that are like cold, long tunnels.  From a child, Snape knew his curses better then the seventh years.  Often seen insulting people or taunting, it's obvious he's Slytherin Head.  Slytherin at heart, man of great ambition, Severus Snape is by far the COOLEST!
