Sinister or Creepy?

I've got to consider whether I want my Emcee to have a sinister manner or be creepy. When thinking of these words to different characters come to mind. For creepy it makes me think of the child catcher from Chitty Chitty Bang Bang, he's very sly and sneaks around tricking children and people with his lies. In some ways the Emcee is like this tricking his audience into thinking they are having a good time but yet still telling them the truth in a comical way.
When thinking of the word Sinister the character that comes to mind it the Slender Man from the computer game. He has long extended ligaments and wears a suit. He lurks in the dark and jumps out at you. When you see him up close he has no face. The word sinister to me also means scary, something to scare you and make your heart race. Even though I want my Emcee to be skinny and have long arms I don't want him to be scary or sinister as if he was like this he would attract people into the club.

I want my Emcee to have elements of both of these mannerisms however for me the Emcee is mostly creepy as he touches the girls all the time and try's to allure the audience. Yet just hiding underneath all of this is his sinister side of drugs and and his long limbs.

The Child Catcher- I consider him to be creepy. 

Slenderman- To me he is sinister.
