All saauke did was neg a meteor and must be badazz, these are feats he could've most likely done when he had his mengekou sharnningan and susano bow that meteor. I was looking forward to sasuke getting both arms or at least his mastery with the rinnegan. but if sasuke got both arms then just saying...there would literally be no need for this movie, sasuke would deva path and neg toneri. Toneri wants to absorb? Preta path, moon collision? Solo clap, meteors? Perfect susano. Clan members? solo glance, puppets? lel sasuke negs them LOL , Literally the plot for the movie should've been giving sasuke's other arm back then Naruto wouldn't do anything and just chill. Heck sasuke deva then human and preta path toneri and GG.
I do have one thing the machine path is naraka right? Why does sasuke need a prosthetic arm when he can make a mechanical one?
