Forum:Film Z

Firstly a question on the actualy film. Didn't they say Z lost his arm to a shichibukai and that's why he had to have that mechanical one? So when Luffy destroyed the robot arm why was Z then able to use both his arms (hence the black fist name) to fight? Shouldn't his right one have been missing?

Secondly the thing with Aokiji... If this is non-cannon then will the straw hats act like nothing has happened when they see Kuzan for the first time in the manga? I assume with his leg missing that they'd remember him, so how is Oda going to mesh the manga with this movie if the film itself is not cannon?
