I am always thrilled to see Supergirl appearing in titles outside of the Superman Family ones. And I am especially happy to hear from others who let me know where I should be looking for these cameos.
So let me thank blogfriend Bookwormwithanattitude for cluing me in on Kara's cameo in Batgirl #8. I definitely would have missed this otherwise.
It's a brief appearance ... just one panel.
In the story, Red Robin and Batgirl are in a confrontation with the League of Assassins who have blanketed Gotham City in a media blackout. Luckily, Oracle is able to get through and send Supergirl out to smash the satellite emitting the jamming signal, allowing Tim and Steph to beat up on the assassins.
It's a nice little spot showing that the friendships between Supergirl and Oracle (as seen in the 2008 DCU Holiday Special) and Supergirl and Steph (as seen in World's Finest #3) are part of the fabric of the characters. I especially like how Oracle's codename for Supergirl is 'bluebird'.
As for the rest of the book, I have to admit that I don't usually get Batman titles and so I only know a bit about Steph and her history. That said, the chemistry between her and Tim Drake in this issue was solid. Even without knowing the details of their history, their exchanges crackled. I don't think I'll be adding this title to my pull list (I get too many comics as it is), but I might stop by every know and then. It seems that this title is really about Batgirl becoming a hero, one of the big themes I like in Supergirl.
Anyways, thanks again for the info Bookworm! This was a fun issue to read.
