i wonder what kind of attacks the juuby has, it even has a sharingan with 6 tomoes. i assume that it can use dojutsu and all the techniques that the EMS and rennigan user has: amaterasu, tsukoyumi, Space-Time ninjutsu, preta path, deva path... but it can't use sealing techniques and i think that the uzumaki sealing jutsu will be the key for defeating the juuby.
