Derived from the question regarding the identity of the person within Sixth Edo Tensei Coffin summoned by Kabuto Yakushi in the Naruto Manga, which appeared to gain a
significant reaction from the normally unshakable Madara Uchiha, which has started a rampant stream of theories and suggestions for the interest of
speculation.
Can be seen and referred to also as a plot device where the appearance of any unseen/unknown character whom holds some key significance to the story, by causing a shocked or emotional reaction/outburst in an
important/major character.
