The only sprite that looks a bit iffy to me is the chick+butler (can't remember their names) from the battle frontier in platinum.
I'm assuming it's safe to link to his trainer sheet since it's not another forum and every other site I found through google is linking to it.
Extraction and public sharing to like 50 other sites found through google courtesy of Veekun.
EDIT: A new thread with sprite extractions was posted, better if I just linked to that. xD
