^ Was assuming that was some kind of coincidence. I don't think Kishi does real world references very often, yet he decides on this one?
Maybe he just likes the mechs and exoskeletons.
Anyways, this chapter explained why everyone was afk when Naruto was getting killed (let's face it, that's what Madara was doing). Oh, and Sasuke too.
Pretty surprised that black zetsu is so crazy stronk, though I'm guessing that Tobi's corpse and some assistance from Madara are big parts of it, having five elements you can use at the same time is pretty OP.
