All these awesome baddies can be found in the sweet reprint volume Bat-Manga! The Secret History of Batman in Japan. Since I just totally sold out to Amazon, you can click the thumbnail to the left to go directly to where you can order a copy. (Assuming I'm doing this product link thingy right.) Or order it from your local comics-type retailer. Or you can do what I did and borrow it from your library, assuming your local library is as supercool as mine.
