There's not much known about her beyond implications such as reality warping (seeing as she can instant-kill and grant immortality to others) and having some form of immortality. As a result, I wouldn't picture conventional methods of attack offing her and you would need a decent level of hax to permanently dispatch her.
I am pretty sure you can blitz someone like her, she still needs to be able to think/react faster than what she wishes to warp, so Goku blitzing her is not out of the question, unless her power is along the lines of someone like Beyonder or something where is just happens casually, in which case he is screwed.
