There is no Kill like Uchiha Overkill
so true. that meteor at the end was like a tactical nuke of a surprise. although this has me wondering... would undead madara be evil?
then again, I have a feeling that Tobi is indeed madara, but what must've happened is that he used the same cloning technique as Muu to make a permenant clone of himself that lived on after the big battle with the first hokage to be the menace that we all know and hate.
