This is my man (he looks like WW but definitely is a Vash)
One headcanon I have for all Vashes across the board is that they're all random noises guys. They go "whoa!" and "wahoo!" and "ough…" and "yeowch!" and "boom!" and even a good old "yippie!" whenever life allows (and, of course, when wildly inappropriate). Man who comes with his own SFX department 🌪️✌🏼
