Of course she was brave to stand up like that but when you think about it,
it was totally unnecessary for her to make new enemies when she could have bought time, even though there is little time. Instead she made more enemies and now everyone will soon be against her. Then she'll have no one to blame but herself. I don't like thus situations.
Sure she is a sannin and a Hokage, she needs to think deeper.
He defeated Jiraya with only 3 bodies and non of them were God realm. Jiraya may be strong but he chose Pain as a opponent at the wrong place on a wrong time. Even though he had no choice. He was not prepared enough, may be because he didn't knew anything about him but still. And this is not one of those HAX filled Oro VS Itachi fights where it's all out of place ..
And I have to say Indeed... All respect goes to him for the time being.
And he HAD to kill the f*cking frog, stop caring for such useless being...! Did you read my spoiler tag at the end?
