That's like saying Jiraiya's and Minato's rasengans couldn't bust a water tower because it never happened in the manga.
Nah ,i only want a clue in which suggests that she actually did ,people use this panel most of the time
You must be registered for see images
but nothing actually shows that she did ,kishi didn't hint it like he does to tsunade or kisame.
but if you're saying that she regenerates because of the fact that she has byakougo then yeah i would have no choice but to agree ,cause databook clearly states that whenever you unlock the byakougo seal ,it can regenerate all the injuries on the body.
What bothers me is that people use that panel as if she actually regenerated in which she obviously didn't ,i know that its possible but being "possible" isn't enough to count it as feat.
