Also, Kisame called Madara a former Mizukage, and he's the only one that's seen Madara without his mask during this series, so is it possible that Madara is not Madara, but is actually the 4th Mizukage?
I don't remember the numbers, but I think it was:

-Jinjuriki Mizukage
-Madara
-Woman Mizukage

Madara's the bloody mist guy.
