Some people even went so far as to believe that the Yondaime, though it was clearly stated that he died fighting the Kyuubi, somehow survived and lived on to become the Akatsuki leader. They believed that everything - from the sealing of the Kyuubi inside Naruto until the hunting of the Jinchuuruki by the Akatsuki - was all part of an elaborate plot concocted by the genius mind of the Fourth Hokage. They believed that what was shown about the Yondaime was just a hoax, he was actually evil despite the fact that all the people of Konoha loved him and that he was willing to die for them.

However, there were many people who disagreed with these believers of 'Yondaime is Naruto's father theory' because they couldn't understand why a father would seal something like the Kyuubi inside his own son. Some believed that it would just be 'too obvious' and that Kishimoto can't possibly write something so obvious - there has to be a twist. Some believed that the Yondaime was Naruto's uncle, or brother, or some other distant relative - just not his father.
