I'm very curious what makes you think the person who created the villain Onomatopoeia has any skill or interest in presenting a "menacing" villain.
I mean I'm open to hearing the reasons, certainly. It's just... it's Kevin Smith. The "Batman pissed himself" guy. I don't think he can write "menacing" without taking the piss out of it. And I say that as a reasonably big fan of his work.
