Cassandra Cain Batgirl Action Figure :: Mattel 2007
I suppose it shouldn't have been a big surprise, as Mattel was able to re-use about 92% of the parts from the Barbara Gordon figure they had released previously in the same line. But still, she was an unexpected (and hard to find) character.
The headsculpt and sweet massive-pouched belt are the only unique parts to this figure, and the only paint apps are the bat symbol and some silver trim (some of which is completely unnecessary, but you gotta admit the silver stitches on the mask are pretty sweet!)
Comic book logic at it's finest.
Cassandra Batgirl was pretty tough to find at retail, so I consider myself lucky to have her. She's a cool and unique addition to my plastic Bat-family
