Spy Smasher (Katarina Armstrong)

Katarina is a high-ranking anti-terrorism agent who is affiliated with several American, Commonwealth, and United Nations agencies. Her relation to Alan Armstrong has not been revealed, though her secret identity and costume seem clearly inspired by him. She has a domineering demeanor, and is not hesitant to kill or order deaths in order to complete a mission. Having forced Oracle to work for her, she plans to take over the Birds of Prey organization and usurp Oracle's position. Katarina and Oracle were friends in college. At some point prior to Katarina's debut, they became rivals. They both competed in a race, with Katarina beating Barbara by cheating but immediately confessing to the judges after she had won.

Katarina accompanies the Birds on a mission in Russia, and in a conflict with the Secret Six, Katarina finds her equal marksman in Deadshot. Katarina assumes leadership of the Birds from Oracle and fires Lady Blackhawk for dissent. Back at Oracle's base, she is challenged to a fight by Oracle, who then manages to give Katarina a proper beating. She is humiliated when she faces the united front of every single one of Barbara's living former agents. Spy Smasher leaves disgraced after being threatened by Black Canary, but before doing so also gives Oracle information on Misfit's background.
