Still needing oxygen just happens to be one of the remaining options, like most organisms. Exclusive would be kryptonite. It isn't exclusive. I never said it was. I am saying that she is the one to encounter it the most. Like Barry may not be the only speedster, but he is the only one with the weakness of passing out after a while because he is the most likely to encounter it. Yes it isn't as exclusive as Kryptonite, but it does limit her from space travel with flight and as such is a weakness.
