People keep missing my point. This is not even remotely unique to Catwoman and takes advantage of a vulnerable window in wakeup attacks. Any string will work as long as it doesn't just outright whiff and you have the execution to time it correctly. I mentioned Deathstroke because his wakeups hit while he's still in invincible frames, and is therefore never vulnerable to this particular tech. It's not about whether there's other ways to blow him up, it's just that people seem to think there's some special property at work here.
I have to wonder how anyone fights Raven not knowing the above.
