I think it's Sasuke's new and awesome true form, and rather than just a mind control thing.
the design looks a lot like a 'main character transformation', so I don't he'll waste the design. especially after the 'evil duck' shit.

Madare. I don't even care enough to speculate. he's not the first villain who just wanted to chat with Naruto (well, he's the second, the first being Itachi), and those conversations never get us anything (other than the joke about Naruto sucking Itachi's big black cock)

Samurais? Really? couldn't they at least do something before fuckin' up so hard? it doesn't even serve a point to say that Sasuke is strong. it just makes the country of iron look like an even bigger land of pussies. Light/chackra sabers? it's nothing new.
