DFF Images Edit
I was able to find the images for Kain, Tidus, and Ramza's alternate outfits without the watermarks. As for Vayne's, I did find an HD version of his render, but no transparent one yet. I will keep looking, and work on one since the image I found for him is big. I'll also try to make transparent renders for the other three. The other four images you were looking for, I think I've already uploaded similar images to the wiki. Are these the ones you were thinking of? Golbez Sephiroth Cloud of Darkness And, while I didn't upload this one, is this the Noctis one you're referring to?
