>>119950073The problem then lies in the fact that:
#1 she could've told them to go faster than normal. And if she didn't, why not?
#2 even if the Flashes were moving at their most "basic" super speed, it still would've been more than a cat burglar with some martial arts training could've taken on. If it were just one Flash, with her knowing well in advance, I could buy it. But these are three Flashes within seconds, if not microseconds, of each other getting the shit kicked out of them.
The velocity alone would've made it far too difficult for Catwoman to kick all of them, keep momentum AND balance, and still have enough strength to knock each one down.
