jesus christ. He's fighting a fuking god. give him some slack. the fact that he's not acting like his normal self is because he's experiencing trauma from Obito being evil and behind everything.
the only reason Tobirama is reacting to things quicker than Minato is because Tobirama is calm and normal. Minato is dealing with the sadness of his student and trying to protect his son in the process. Minato's got way more on his plate to worry about than Tobirama does.
Edo KCM Minato stomps pretty much anyone in the show besides Juubito.
"But Steinbiz, what about Madara?" Please. Tell again how Madara hits KCM Minato.
Not only right now, but when Obito attacked the village 16 years ago, Minato did damn well having to worry about his family and the entire village while dealing with Kurama(full power) and Obito. Minato is pretty much known for dealing with dire situations, under huge pressure.
