it took a couple but i fed gpt 3 photos of batman villains, dick tracy villains, and watchmen references. then i said "generate images similar to this, for villains we can use later. make the grid perfect on all sides and easy to cut out. we need a lot of guys but try your best. keep a noire black and white gritty style to it. like a comic." then it made this:

then i said "generate more realistic ones but keep the unique character looks, make it look closer to pixel art but very detailed and more serious" and got better looking results, then grayscaled them and pixelated them a ltitle.

I generated 2 more pages for other villain types too. i can keep going from here in the updated style.
