Invisible Man could work for some pretty creepy audio moments, but I'm not sure he could hold an entire show with that.
Meanwhile with Wolfy, you could really go all in with both audio and special effects (think the floor rumbling as he's running around, or (like AE) the sound and feel of him sniffing and breathing right on your neck as he's looking for his next victim).
I think the closest monster there is to that would be Drac, which would also be pretty epic.
