Here is a small gallery of some Knuckles images I had laying around that I thought were cool-looking. You're free to use these in icons or layouts if you want, but I posted them mainly just to be looked at. Sorry for the quality of the first three. I had every intention of scanning them, but my scanner gave out, so I just took pictures. I'll try scanning them later if I ever replace my scanner.
The last two were donations from my friend Nori. She scanned them from the Sonic Adventure game guide. They're in much better quality than the ones I contributed. :P
Should you use any of these images, credit is not necessary. All I ask is that you not put the images in your own gallery, as that would defeat the purpose of mine. Thanks.
