Organization ZERO has one purpose, to collect all of the bijuu and use their fierce combat abilities and godly caliber chakra to spark a world wide disaster and war. After this, through a forbidden sealing jutsu, they will begin to awaken and give new life to a beast named tragoedia, a well known demon from the sage of the six paths era that was however, sealed away far in the core of the earth from the sage, like the juubi that was sealed into what is now called the moon.
