First appearance: Batman #676 (June 2008):
Unfortunately, she's only shown as a member of what is being called the "Club of Villains", a group composed of those who have gone up against the international heroes from the "Club of Heroes".
We also don't get to see Scorpiana in action in the following issue, Batman #677.
Things look much more promising for her appearance in Batman #678 (August 2008) when she goes up against Nightwing!
But, alas and alack, we never get to see how that confrontation goes, except for the fact that Dick later winds up imprisoned in Arkham Asylum somehow.
At least in later issues we eventually get to see Scorpiana do more than just stand around and pose.
