Madara Because he is one of the most legendary Ninja ever and he knows somthing about Tobi's plan and bunch of other things i want to know what he knows
I'm actually quite interested in Kabuto's backstory at the moment. Need Moar Flashbacks!!! I kinda feel sorry for him 'coz he just wants to know who he really is.
