How about an “H”?
updated with those letters 
Were there any A’s? You didn’t put any but you also didn’t put the first letter of HANGMANX either. 
No A’s. Sorry missed your post :oops:
So much for my theory that it started with “The cat in the …” 
I’ll guess the E.
The pit of the Netherwitch?
Correct your turn Zax!
All right, let’s try this:
_ _ _ / _ _ _ _ / _ _ _ _ _ _
I’m going to guess: The Zaxx Factor
Haha, yeah, that’s it. There should be a special prize for solving the puzzle without any letters!
Let this stand as evidence that I do know how to spell Zaxx, despite my handle. When I was looking to change my screenname back in 2005 or so, thezaxxfactor was taken on AIM, so I opted for thezaxfactor with one X. Since then I’ve been misspelling Zaxx all over the web. :oops:
Your turn, CoT!
THE * KEYSTONE
Congratulations keaton!
Wrong Guess: The Doomgaze, L
Hanging the man: H A
The Doomgaze? 
If not, I’ll guess an E.
Not The Doomgaze, but there are some E’s.
Is there a “T”?
There are two t’s.
I’ll go for an easy one and guess “H”.
And you got the easy H.
Is there an “L”?
Sorry, no L’s.
How about an “N”?
