[Batman] Batman wants to be an agent of fear and dread to the criminals of Gotham, so why not wear some kind of fangs or set of sharp teeth? Doesn't his mouth just give away the fact he's just a guy in a suit?

I mean he's got glowing eyes and a menacing voice modulator. Why not go the extra mile and cover his mouth with something equally scary. I don't mean a comical Dracula fang, but more like a set of animalistic teeth or something?

I mainly got this idea because in Batman begins when scarecrow is induced to the fear toxin and sees Batman, he looks freaking demonic! Those sharp teeth really do make him completely different.

He fights in the shadows, uses smoke, can seemingly silently teleport using grapples or moving silently, he has two large horns protruding from his head, and makes a habit of sending thugs into comas. Anyone who gets close enough to see his teeth is either unconscious or is a near equal fighter (ie not scared by the tactics)
