Who the hell said tsunade could regenerate an arm or her head if they were cut off. Are you joking. that would make her Oro and he can only do that because he used forbidden jutsu on himself
I don't know who said that. But once you're close to Tsunade you can't touch her because a single blitz from her could send you meters away. Or she could interchange your brain shockwaves and change the responsive movements as she did with Kabuto. By only a simple touch.
6/10 is pretty fair imo. idk why though kunais are seen as useless in this fight after one has been casted in genjutsu. could tsunade heal if shes chopped up?
Who could chopp her up? People tend to forget that as her primary skills are the evasive ones. And the secondary ones, medical, are unmatched in the Narutoverse.
Considering Konoha had constant attacks from the uchiha it is possible he developed a counter similar to how gai developed his not saying they are the same but just because she is senju doesn't mean she is supposedly immune to genjutsu
Another special thing about itachi is that opponents don't realize when they are in genjutsu once again orochimaru was used as an example he also as finger genjutsu
The way I see it only someone with sharingan can stand up to otachi's genjutsu if they are caught.
She is the second who could get to the same level of healing as Hashirama.
That was stated and praised by Madara himself, the antagonist no. 1 in Narutoverse.
Yes, a regular opponent won't notice it because it has to do with chakra control, but Tsunade having perfect chakra control I am sure she would notice in a blitz.
People also tend to forget that she knows or can read the pattern of her oponents as she teached Sakura to. Chyio praised Sakura for starting reading the patterns of Sasori's movements herself, not even a single help from Chyio.
If Sakura who is a genin can do that, imagine Tsunade.
That's the way you see it, not necessarily the outcome as the feats presented by Kishimoto for Tsunade show that genjutsu/tsukyiomi can be countered.
