edit: Sick of all the Batman doesn’t use guns whining so i’m throwing this out there. It’s the wild west, the gun was all there was in the way of dispensing justice back then. I’m pretty sure billionaires and fancy gadgets weren’t exactly common place either. Get over it, enjoy the concept and enjoy the art. Your heroes are safe.
I notice there are no comments on The Flash packing a couple of six shooters or the fact that they all have belts with bullets in them either? The only one who doesn’t is Wonder Woman, which makes sense as she has the Lasso.
Calm down, it’s just a conceptual re-design for fun.
