I'm not sure if I have missed anything in the past, but Madara seems unphased by every attack.
Sasuke stabs a sword through his arm, but this isn't a problem.
All the tailed beasts stomp on Madara with their tails, and Madara doesn't even evade. Instead, he tanks the attack like it is no big deal.
What's going on here? Hashirama's senjutsu should only do so much, but it seems like Madara is simply invulnerable, aside from a little bleeding. Why isn't Madara getting hurt at all?
Is this what we call a plot shield?
