Small detail regarding Kisame and Tobi's meeting
Remember when Tobi first revealed himself to Kisame?
I just found this on the wiki:
When Tobi reveals his face to Kisame Hoshigaki, the latter identifies him with "Mizukage-sama" (水影様, Mizukage-sama). In the tankōbon version, he instead refers to Tobi using "former Mizukage-sama" (元水影様, Moto-Mizukage-sama).
That means it was fixed to "former Mizukage-sama" in the newer tankobon version. Now I think we can interpret this in two ways:
1. Kisame was being a bit sarcastic, which means he was only saying that Madara/Tobi can now stop pretending to be the Mizukage, thus making him the former Mizukage in a way. This is more probable for now.
2. It means that he recognized him as the Third Mizukage, meaning that at some point Madara had some affiliation with the Hidden Mist, perhaps because of his hatred towards Konoha. Not sure how this would fit into the timeline, but I would label is as improbable.
This particular part of the Tobi/Obit thing still bugs me. How could Kisame recognize him as Madara? I'm pretty sure he wouldn't be fooled by a transformation jutsu. What do you think?
