K-Bee is pretty cool. He seemed like such a dumb ass before, but it was interesting to see that he is friendly with his bijuu. It was sad to see the Raikage worry about his brother -- I guess that explains why Hachibi was the "first" bijuu taken to get an international response. (Yeah right, Shukaku gets that honor). Also, I can't imagine kage-level lightning jutsu being weak.

Also, Pein. Finally. Invades. Konoha. Naruto didn't even make an appearance in the chapter. Konoha is toast.
