Tobi is not Kagami. Why? He was a character who was shown in 1 chapter, and never even spoke a word. The ONLY reason people even make Tobi theories about this guy is because they know his name and he is an Uchiha. And then they come up with WONDERFUL fanfictions about how he got to be evil, his connection to Madara, and all of this crazy stuff. But the fact of the matter is that he is a character who has NEVER said a word, was NEVER spoken about by ANY ninja ever (no hype AT ALL), has NOT been developed or affected the plot AT ALL, and the only panels he's been in he has been sitting down. Honestly, Kagami being Tobi theories have started to get more annoying to me than Obito being Tobi theories, and that is REALLY hard to beat.
