- Doctor Crane kept me in a box screaming for months, pumping each new iteration of his fear toxin in, perfecting it to use on Batman. I know uncomfortable, Batwoman. And I know deep down that you and Bats are just like us. You experienced something horrible that fractured your mind, and now you're terrified what will happen if you stop fighting. But I can take that fear away... this toxin blocks all fear from the mind... Without that cloud, tell me, do you really want to be doing this? Wouldn't it feel better to just give it up and go home?

Abigail O'Shay was a student who wrote her doctoral thesis on vigilantes like the Batman Family, which she called the "cape and cowl" crowd. She was fascinated by kind of trauma a person would have to go through in order to fight criminals in the manner that they did. Before long, she found out for herself. Kept as the test subject of her own professor, Dr. Jonathan Crane, better known as the Scarecrow, O'Shay was given many iterations of his signature fear toxin to test its readiness to use on the Batman. Even after being saved, she spent more than a year in Arkham Asylum recuperating from Scarecrow's experiments. Blaming the Batman for her trauma, she joined the Victim Syndicate with the intention of making sure no one has to feel the same fear she did ever again.
- Hand-to-Hand Combat (Basic): Madame Crow briefly (and unsuccessfully) took on Batwoman hand-to-hand, demonstrating that she has at least some fighting skills.
- Paralytic Toxin: Madame Crow had access to a paralytic that could be released through one of the needles on her hand, enough to temporarily paralyze Batman.
- Anti-Fear Toxin: In a reversal of Scarecrow's toxin, Madame Crow has a set of gauntlets that fire needles filled with "anti-fear" toxin, which removes fear in the hope of keeping people from fighting to avoid their own trauma.
