Hi i just wonder why people still claim that Tobi is Izuna Uchiha .. at first it sounds Possible but after Edo Madara entered the Battlefield he stated that Izuna left him and all what he gave him where does Eyes. That Implements that madara thinks that Izuna is dead and i think Madara knows Tobis true identity because there working together excuse me when im wrong. And again sorry for my bad eng.
