I always welcome more Batgirls, but I don’t see it happening for the following reasons.
1. All of the Birds of Prey know Cassandra Cain and know her well. Sure, White Canary in Birds of Prey was wearing a half-mask, but they’d still know her. And wouldn’t it be a little awkward to introduce this big mystery character on the last page of Birds of Prey only to have the characters go, “Oh, hey Cassandra,” in the next issue? I guess we’ll see.
2. White Canary? Really? That’s the title? A spin-off of an already shuffled around character? That’s not the strongest title for a book. ‘Cassandra Cain,’ would be a much better title all on its own. You have the alliteration, the allusion to the homicidal Cain in the Bible. It’s like Damian Al Ghul. That’s an evocative enough name, and by this time a well enough known name, to stand alone.
3. As I understand it, when Ian Sattler was asked at Heroes Con, about any upcoming Cassandra Cain books, he said they planned to leave the character alone for a couple of years. In my experience, the default answer for these things is ‘sure, ____ might come back soon,’ no matter how unlikely it is, so if someone is actually willing to say that there’s nothing planned, there’s probably nothing planned.
Or are they running a double game on us?
