Also, Obito and Madara may not have activated 6 Paths Sage Mode.... there is a possibility that they underwent Sage Transformation, unless the databook says otherwise. Obito and Madara didn't use Six Paths Sage Mode, but according to Madara they did possess a form of Six Paths Senjutsu. The databook refers to the Ten-Tails jinchūriki transformation as. Though it probably means it more as "Sage of the Six Paths Transformation", as in turning into the Sage himself. Not sure if it's meant to be an official title for the form or just a description of it.
