Because Cassandra Cain has never really gotten the toy love she deserves-- most Batgirl figures have been of the Barbara Gordon variety, which makes sense because she's the character the rest of the world tends to associate with the identity-- she's been turned into some sweet customs here and there. Here's a link to a very slick-looking Black Bat custom job. The smirk is decidedly un-Cass-like, but the costume is perfect. Actually, the Black Bat identity is more interesting to me as a custom possibility because of the exposed face and hair, the challenge of doing that pointy domino mask and the interesting texture and contrast of the forearm wraps.
I'm going to keep an eye out for more of these.
I love custom action figures. When I was a kid, I was forever painting up different figures to supply cast members of whatever imaginative adventure I'd dreamed up. Of course, mine were rinky-dink efforts compared to some of the skilled craftspeople you encounter online. My idea of a sweet custom was taking a banged-up Kenner C3P0 and painting him blue to represent Han Solo's old droid buddy Blue Max (although he looked more like this custom) from the Brian Daley novels, or painting some greenish-gold Acroyear parts red to make the exiled king from the Marvel Micronauts comics. A couple of years ago I accumulated the raw materials for a Battle Royale Chiaki Kuriyama 1/6th figure but realized I just didn't have the skills to finish the job (someone made a nice one from a Gogo Yubari figure, though). These people today with their 3D printers and their Super Sculpey and whatnot occasionally produce amazing models that look better than a lot of the stuff you can buy from legitimate toy companies.
