Click Here Click Here I've notice that after summoning the statue, AL performed a jutsu and it was done by the statue itself. What if the purpose of the statue is after gathering the power of all bijuus inside it, to become a mobile remote controlled weapon of mass destruction? Like Kyuubi once attacked Konoha, Akatsuki's ultimate goal might be to use a all in one bijuu creature to attack and control the entire ninja world. AL said "If we include the Kyuubi, everything will be in our hands". The only creature that could fight such weapon would be the Kyuubi himself. So if they also harvest his power into the summoning, nothing can match it.
